However........... 2) I will posit it's not necessarily a 100% "for sure/correct" suggestion to opine, "If you do not have resonant antennas for all bands, then you will want the KXAT3." 'cuz, it really depends.................the below scenarios should provide examples that support my above posit: Scenario #1: If you have installed a "non-resonant antenna" of sufficient length to operate at the lowest frequency of interest, with a properly fed auto-tuner at the base (a vertical) via a short (< 10') run of low loss coax OR at the center feed point (a dipole, including OCF) via open wire feed line to the auto-tuner located outside with coax between the auto-tuner input back to the shack AND you intend to never take that $1300.00 + radio out of your shack, an internal ATU is worthless. Scenario #2: You erect a vertical or dipole of sufficient height/length ("sufficient" means tall enuff to be nearly a 1/4 wavelength at the lowest intended frequency of operation), can employ open wire feed line all the way back to the shack where an efficient auto-tuner that costs less than the KX3 resides, understand how to wind a matching transformer (do not infer I am including a balun or un-un in the discussion of a matching xfmr), will employ same xfmr to transform the 600 ohms of the open wire line to near 50 ohms AND intend to never take that $1300.00+ rig out of the shack, you don't need to purchase Elecraft's internal ATU. 72 de Jim Rodenkirch K9JWV On 1/30/2016 12:24 PM, Tomy Ivan via Elecraft wrote: > Looking to buy a nice KX3 Package.Please let me know what to have. 73! > Tomy KF7GC > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] -- View this message in context: http://elecraft.365791.n2.nabble.com/WTB-KX3-tp7613318p7613384.html Sent from the Elecraft mailing list archive at Nabble.com.

It's noise cancelling and everyone I talk with loves the sound quality over the cell phone mic. I would need a Y connector that has an output for the headphones on the K3 and a 2nd one with a mic plug for the K3. I have a female with a cable & bare wires at the end that I thought was for a mic but apparently it's for the headset and the internal connections don't match that for the mic. The male plug is like a stereo mic; same overall length with the tip and first ring the same dimensions but instead of a long sleeve on the headphone plug, the sleeve is cut in half and there is a 2nd ring. Anyone know of a good adapter that will fit this to the K3?

It's a Y with a TRRS-F to 2 TRS-M. Search Amazon for "TRRS Adapter" and you will get lots of choices. Make sure you get the right genders on both ends. You will likely have to set bias and TX equalizer to make it sound right.

You might find this URL helpful, just focus on the pictures on the first page. http://www.murata.com/~/media/webrenewal/products/emc/emifil/knowhow/26to30.ashx Figuring out what type of noise you're dealing with is the first step to reducing it. You might find it easier to replace the LED driver you're using with another unit and see if you get an improvement. 73 Matthew VK5ZM On 2 February 2016 at 14:18, johnpierce wrote: > My kitchen, under cabinet lights, are LEDs.

From this and your description, I would speculate the power supply is the guilty party that is creating the RFI and it should be replaced. Case and point, I went through three different chargers for my HP laptop before I found one that didn't create RFI issues. And note too, they were all "certified" according to the labeling on their cases. 73 Bob, K4TAX On 2/1/2016 9:48 PM, johnpierce wrote: > My kitchen, under cabinet lights, are LEDs.

It's a problem that any RBN node potentially has depending on their equipment. It's a known problem with simpler SDRs, or with a more expensive SDR with something on the fritz. Don't tear your K3 apart looking for the problem or send it to Big E. AC0C will have to deal with it. 73, Guy K2AV On Tue, Feb 2, 2016 at 12:27 AM, Milt -- N5IA wrote: > Mike, > > From my remote station which was operated by KY7M in the contest, I > noticed the same thing from the AC0C RBN box. > > However, in this case the QRG of KY7M was 1.820.6 and the other recorded > transmission by AC0C was 1.864.7, a 44.4 kHz difference. > > Your noted difference was 25.4 kHz. > > Perhaps someone smarter than me can figure it out.

This could happen if the receiver in use was subjected to a signal beyond its usable dynamic range. For example, a very strong carrier could mix with another strong station's CW to create "ghost" signals (third-order intermod) for the duration of the carrier. Another possibility is demodulating a strong signal due to a spur in the receiver's local oscillator. Such scenarios are much more likely during heavy contest activity.

The keying LED lit, but no power output was seen. K3 is #1504 and it has new synthesizers (2) in it. I also recently replaced the connector pins to the 100 watt amp, but I think that the first episode happened before I had the rig apart to fix the pins. It almost sounds like the LO is dead when first turned on. There were no error messages, and all looks OK, except that no signals are heard. I am going to check a bit deeper. First thing is to look for a proper LO signal to the receiver. (TMP connectors etc) Any ideas from the gurus?

When I change from CW to SSB, the FC is 1.75 instead of 1.50, so I have to move it to the left to get it back to 1.50. How do I get it set to 1.50 and stay there on all bands.

This was proven to be the broad RF input for the RF remote control portion of the receiver. No amount of ferrite on the cables helped. Even after they were switched to IR Remote, no improvement. Finally I wrapped the units in Aluminum Foil leaving a small 1/2" window for the IR remote signal access.

(Among others, I copied BG4GOV in Shanghai.) Many of the signals were not copyable until I turned on APF (audio peaking filter). This filter's center peak is very narrow (around 30 Hz), but the response broadens out quickly below the 3-dB points in the curve. This brings up the desired signal without allowing noise to cause ringing--something often heard with narrow filters of the "brick-wall" variety. On a noisy band, the effect is just short of magic. APF is very narrow, so you'll need to tune in 1-Hz increments when it is turned on. Also, APF works best when used with a DSP/crystal filter WIDTH setting of 300-500 Hz. Use of APF differs for the three transceivers. KX3: 1-Hz tuning is selected automatically on the when the APF switch is pressed. K3/K3S: APF is accessed via a hold of the XFIL switch. This function is labeled "APF" on a K3S, or "DUAL PB" on the K3). Use CONFIG:DUAL PB to make sure the selected filter function is APF. See the K3/K3S owner's manual for a description of the alternate setting. 1-Hz tuning can be selected by tapping FINE. You might want to give APF a try if you haven't already. 73, Wayne N6KR From rmcgraw at blomand.net Tue Feb 2 09:44:57 2016 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Tue, 2 Feb 2016 08:44:57 -0600 Subject: [Elecraft] APF (audio peaking filter) on the K3/K3S/KX3 In-Reply-To: <4FE5BED3-C547-464E-B696-423E23A52EC5@elecraft.com> References: <4FE5BED3-C547-464E-B696-423E23A52EC5@elecraft.com> Message-ID: <56B0C0E9.1060402@blomand.net> As a new K3S owner {since last August}, I agree.

CFLs draw more current as they age. Eventually the power supply is overwhelmed by the current demand and fails. All the CFLs I've seen use a tiny (1/8 or 1/16 watt) resistor as a fuse. Before anything else gets overloaded enough to fail, the little resistor acts as a fuse and opens. But, being a resistor, it fails like a resistor often with some smell and brief puff of smoke. I suppose it might be possible for a flame as the covering burns, but that should be inside the base enclosure. I've never seen anything but a small puff of smoke if I am looking in that direction when it goes. 73, Ron AC7AC -----Original Message----- ... a couple of those so called "5000 hour" Chinese CFL's actually burned up (yes, smoke, fire and flames) Jim - W0EB From k2av.guy at gmail.com Tue Feb 2 12:50:12 2016 From: k2av.guy at gmail.com (Guy Olinger K2AV) Date: Tue, 2 Feb 2016 12:50:12 -0500 Subject: [Elecraft] SSB shift frequency In-Reply-To: References: Message-ID: I am assuming that FC refers to the "FC" in the VFO B display and you are referencing filter center.

Guess I've been lucky over the years. After finding some brands of CFLs that are don't generate hash across the HF spectrum, I am just starting to experiment with LED replacements as the CFLs die. One trait of the CFLs that I miss in the LEDs is that CFLs take several seconds to come up to full brilliance. I found that much less jarring on the eyes, especially in a darkened room. 73, Ron AC7AC -----Original Message----- From: Robert Nobis [mailto:n7rjn at nobis.net] Sent: Tuesday, February 2, 2016 10:22 AM To: Ron D'Eau Claire Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] Noise from LEDs Ron, I have had two CFL?s fail that were well beyond a ?puff of smoke?.

Many of the cheap foreign LED modules use very cheap components in their drive circuitry. There are very RF noisy and cover a wide bandwidth, The RV industry switched to interior LED modules in the last few years and there have been loads of complaints of interference with radio and TV signals. If you have a linear power supply you can connect to drive the LEDS you can isolate the problem. -- View this message in context: http://elecraft.365791.n2.nabble.com/Noise-from-LEDs-tp7613396p7613426.html Sent from the Elecraft mailing list archive at Nabble.com.

Two in one bathroom do. Especially 15m & 6m. I have both generic & Cree bulbs in use. If there's LEDs made anywhere but China I've not found them. On 15m & 6m it's bad enough I make sure they are off before chasing weak DX. I believe the VP8 Dxped is running K3s. The standard these days. One of them they're using on SSB has what I'd call 'mushy' audio. Others have noticed it too. Whether it's mis-set or the generators I don't know. Still very readable but not quite right.

Message-ID: <1454455503221-7613427.post@n2.nabble.com> Hello group, I've found minimal information on whether or not the K3/0 actively handles audio from the front 8 pin microphone jack before exiting the rear 1/8" connector feeding the mic input on the RRC Control unit. I can change settings for the K3/0 such as Bias, FP-H/L etc., when disconnected from the network but don't think the changes actually do anything. Is the front 8 pin mic connector hard wired "DC connected" to the rear 1/8" connector and simply a pass through? I know that when connected through to the remote K3 the settings are normally to the K3. I wasted several hours trying to eliminate some "buzz" audio noise when connecting my Heil headset through the 8 pin connector on the K3/0. I finally made up a connector to go from the Heil directly into the RRC control unit. The noise then was gone! So noise is being picked up inside the K3/0, a ground loop possibly? The noise is not 60 Hz, but varies in frequency with the Advances settings in Microbit for the Remote rig. Ideally some minimal settings could be configurable from the K3/0 such as Bias ON or OFF for the local 8 pin mic input. But if the wiring is hardwired and simply pass thru where is the buzz coming from? Documentation and an internal schematic would greatly help! 73, John W1AN -- View this message in context: http://elecraft.365791.n2.nabble.com/Is-K3-0-Audio-pass-through-or-processed-in-K3-0-tp7613427.html Sent from the Elecraft mailing list archive at Nabble.com.

Another possibility is that one of the connections from the rear panel ANT1 and ANT2 connectors is not properly seated in the mating connector on the KAT3 board. If you've not been inside your K3 before, just remove the top cover. If you need a guide as to which of the plethora of screws are involved, download the KAT3A installation manual from the Elecraft web site by clicking on this hyperlink: http://www.elecraft.com/manual/E740266%20KAT3A%20Option%20Installation%20Rev%20A.pdf Figure 1 on page 7 shows you which screws to remove and how to "pop" the cover loose so you can lift it off. (DON'T GET CARRIED AWAY PULLING THE COVER OFF - You'll need to unplug the speaker wire and you don't want to jerk on the connector). Figure 5 on page 9 shows you the one screw that must be removed to free the KAT3 board. Also it indicates one of the rear panel screws that, if removed, will allow you to move the rear panel back enough to wiggle the board around in its connector. Figure 10 on page 12 shows you the two wire connections to the rear panel SO239 connectors I mentioned. OTOH, a rubber mallet might be more fun if you have visitors although I'm sure that will give Wayne and Eric heartburn and, if one of those antenna connections is loose, will likely stop working. As an aside, many years ago I bought a brand new MGA roadster (yeah, I'm an O.T.). Although a thoroughly modern 1960 automobile it had provision for a hand crank to start the engine in an emergency. I had a fun relationship with the agency staff and one time when I was leaving I saw a couple that was considering buying one looking at my car sitting in the lot talking with the salesman. I approached, said "Hi", took out the crank, put it in the bumper hole and gave it a whirl. The engine started immediately while the couple stood there in amazement. I had to stop and explain that I was "pulling their leg", but I never had to worry about a jump if I left my headlights on! The moral of the story is that sometimes the "Armstrong" solutions are more fun. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Allen Griffith Sent: Tuesday, February 2, 2016 4:36 PM To: Elecraft Questions Subject: [Elecraft] Use a hammer? blockquote, div.yahoo_quoted { margin-left: 0 !important; border-left:1px #715FFA solid !important; padding-left:1ex !important; background-color:white !important; } Hello fellow K3 owners,Unusual thing happened while tuning the internal tuner.

Check the settings in the TX EQ first. I would suggest that you initially set all bands to flat. For communications quality, normally you want to reduce the first 2 bands to the lowest settings and the 3rd band by 3 to 6 dB. The lower frequencies take a lot of power but do not improve communications and intelligence. OTOH if your listeners are of the ESSB kind, they like a lot of bass in the response. I have known one instance where that symptom was cured by calibrating the Reference Oscillator. Follow the instructions for Method 2 (Zero Beating) in the manual. Do not overlook the fact that you may have a bad microphone. Take an inexpensive computer microphone and plug it into the rear mic jack, set the MIC SEL to the rear jack and turn bias on. Those computer mics normally produce good quality audio. 73, Don W3FPR On 2/3/2016 1:09 AM, Steve Wilson via Elecraft wrote: > Hi all, > I have a newly acquired slightly used K3.

Close, but if you?re used to using a scope for monitoring, you won?t call it ?live?. Also, the vertical height of the display is always normalized to the peak RF signal and there are no sweep width/rate adjustments. I have not experimented with the CW display modes to see how useful they are. My opinion is that the P3 envelope display isn?t a match for a scope, and probably wasn?t intended to be. I do like having the SWR/PWR indication on the P3 display, though.

I had a business partner who hated fan noise in computers, so would always replace the stock fans with quieter ones (better blade profiles and lower vibrations) and the cost never seemed to be much more than the stock ones. Even though I thought the standard fans didn't make noise, the difference was quite obvious when you ran a pair of machines, one upgraded, the other not.

You've gotten pretty good advice, but I'll try to summarize it to step-by-step. With speech, content below 400 Hz makes almost no contribution to speech intelligibility but uses a lot of transmitter power. That low frequency energy gives the voice more "body," but it also contains breath pops, handling noise, and room noise. We will be louder and easier to copy if we get rid of that low frequency content. That typically gives us 3 dB, Compression adds 10 dB more. The result is to give our 100W radio the effectiveness of a 2kW radio. 1) Go to TXEQ in the menu and check the settings of all the bands. Like Don and Bob, I suspect that the prior owner has set them badly. 2) Set all bands to 0 dB (flat). 3) Now, set the three lowest bands (50 Hz, 100 Hz, and 200 Hz) for maximum CUT (-18). Set the 4th band (400 Hz) for a cut of -3 dB. 4) Make sure Compression is turned all the way down. 5)Now that we have EQ set properly, adjust Mic Gain per the manual. 6)Turn up Compression and adjust it until you see 10 dB on voice peaks in the Comp display when you transmit. 7) Get some signal reports. Ask those listeners to set their receive IF to a fairly wide setting, like 2.7-2.8 kHz. Depending on your voice and your mic, you may want to cut the 400 Hz band a bit more or less, and you may want 3-6 dB peak for the top two bands (this will make you "brighter"). 73, Jim K9YC From wunder at wunderwood.org Wed Feb 3 13:21:53 2016 From: wunder at wunderwood.org (Walter Underwood) Date: Wed, 3 Feb 2016 10:21:53 -0800 Subject: [Elecraft] help with improving transmit eq In-Reply-To: <56B2441D.1030907@audiosystemsgroup.com> References: <1881967253.934639.1454479785549.JavaMail.yahoo.ref@mail.yahoo.com> <1881967253.934639.1454479785549.JavaMail.yahoo@mail.yahoo.com> <56B2441D.1030907@audiosystemsgroup.com> Message-ID: <5B5DB9EE-80E5-4874-85B0-A8985D9B9153@wunderwood.org> I seem to remember that the 3-6 dB boost in the top band was to correct for rolloff in analog receive filters.

I had hum on xmit audio and very low receive audio. I sent it back to Elecraft, they sent it back to me saying it was working - to eliminate digital noise getting on the audio, later K3/Minis have a big honking low pass filter in the audio chain between the rear panel connector and the front panel connectors - that introduces a lot of loss. Their recommended solution was to turn up the audio level in the RRC, but I'm never in favor of amplifying then attenuating. This also would not solve the TX hum/distortion, which the Elecraft tech didn't hear. So, I just connected mic/headset directly to the RRC. Makes the cabling ugly but the audio is FB now. If you have an older Mini (I don't know the serial number cutoff) you might have the noisy audio board. If you have a later Mini, you have the attenuating/hummy audio board. Either way, I think cabling to the RRC directly is a work around. I quickly regretted buying the Mini, should have went with a bare bones K3/10 - I don't really need the KX3 like form factor, have never actually taken it on the road. 73 John K3TN -- View this message in context: http://elecraft.365791.n2.nabble.com/Is-K3-0-Audio-pass-through-or-processed-in-K3-0-tp7613427p7613455.html Sent from the Elecraft mailing list archive at Nabble.com.

Not that I want it to be. Using the analogue line out I get normal L&R channels into MMTTY in SO2V mode running in Logger32. The SO2V channel goes dark if I turn off the Sub RX. All is normal as I have been running it for years If I use the USB audio which presents itself to MMTTY as: Reception: Microphone (USB Audio Codec) Transmission: Speakers (USB Audio Codec) I only see the audio from the main RX in both channels despite the main being configured as left and the sub channel configured as right. Turning the sub RX on or off has no effect except for in the headphones. I would suspect that I have some horrible Win7/64 audio configuration problem which at present I just can't figure out. Anyone got any thoughts on this.

Within the package size dictated, you can only move so much air in a given timeframe, "silently". Quiet is at very best a secondary consideration when spec'ing a fan to protect a multi $K transceiver. If you are really interested in all the factors that I consider when setting the specs for a part in a thermal design, contact me offline. BOTH of the fans that Elecraft have chose/are using are quality ball-bearing units, cool properly, and meet the other engineering limitations. You can go broke purchasing "boutique" parts for ancillary purposes. All that aside... I will likely IMMEDIATELY replace my stock fans with units that meet the airflow, et al requirements, but that meet MY requirements, too. I'll put the stock fans in the box that will hold any OEM parts needed to return the set to 100% original when my heirs sell my estate.

It is, indeed, a matter of compromise between cost and how many customers care about whatever the characteristic you're trying to optimize. At least 90% (and 100% of my serious operation) is wearing headphones, and the times I'm using the speaker I'm monitoring while in the shack doing something else. So I've NEVER been bothered by the fans in my K3/100. I DO hear the fan in my KPA500 when I push the TX duty cycle, so I've guessing that a few bucks spent on making it quieter without compromising cooling would be appreciated by a much higher percentage of users. 73, Jim K9YC On Wed,2/3/2016 1:51 PM, Clay Autery wrote: > Well, there are laws of economics for manufacturers, too.

The first mic I know of that provided that compensation was the Shure 440, as far back as the '50s. The current model is a 444D. The D104 does much of the same thing. Those mics also roll off the low end a bit. Heil's contribution was to use exactly that principle in mics that are smaller, or "sexier," or in more convenient packages, to advertise them as if they had invented the idea, and to raise the price a lot. 73, Jim K9YC From dave at nk7z.net Wed Feb 3 17:48:13 2016 From: dave at nk7z.net (Dave Cole) Date: Wed, 03 Feb 2016 14:48:13 -0800 Subject: [Elecraft] Genovation 24 Key pad software Message-ID: <1454539693.29767.59.camel@nk7z.net> Hello Gents, I have completed testing on the CP24USBHID upgrade software and am happy to report it appears to work flawlessly in allowing the Genovation 24 Key pad, (CP24USBHID), to send macro triggers to the P3.

First, they do introduce some conversion inefficiency themselves - they will draw about 10% to 20% more power from the battery than will be delivered to your radio. Just the nature of boost converters. This will put quite a strain on your battery in any event. You won't get a full 22 amp hours of use from it, i.e. I wouldn't expect much more than an hour of operation at best before it became unusable, but until then everything should work well.. Second, since it is a switching type power supply it may introduce birdies on receive. Naturally this will be worse if near the antenna, or if there isn't a choke on the coax going to the antenna. N8XJK does have a more expensive converter that senses RF and only activates boost during transmit, and takes the converter out of the line on receive. That should take care of the birdie problem. I have used one of their converters in a marine environment, and it worked well. I haven't used one in portable ham operations.

Pressing a CW "M" button starts keying the K3. While the message is being sent, when a second "M" button is pressed (it could be the same or a different button), the word "CHAIN" is displayed and the second message immediately follows as expected. This works great when calling DX. I store "K1HTV" in the "M1" memory. If I want to drop my call multiple times, I can press the M1 key while the previous message is being sent and get my call sign sent as many times as desired. One would expect the same chaining results on voice modes when using the K3's KDVR3 Digital Voice Recorder (DVR). However this is not the case. It is NOT possible to chain DVR messages! One must wait until the 1st message ends before pressing the same button or a different one. If you press a memory button while playing back the recording in a DVR memory, it can adversely affect the message being played. While playing back a DVR message (i.e. sending your call sign twice), if you press a second "M" button, the first message terminates abruptly after 3 seconds or so. Some times a partial syllable burp is heard. What would it take to correct this DVR anomaly so voice messages can be chained in the same way as CW memory messages? 73, Rich - K1HTV From jackbrindle at me.com Wed Feb 3 19:18:09 2016 From: jackbrindle at me.com (Jack Brindle) Date: Wed, 03 Feb 2016 16:18:09 -0800 Subject: [Elecraft] K3S Computer Audio Question with Sub RX installed In-Reply-To: <018801d15ee0$3e74eaf0$bb5ec0d0$@carolinaheli.com> References: <018801d15ee0$3e74eaf0$bb5ec0d0$@carolinaheli.com> Message-ID: <8022D6E7-6D2A-41AA-B41C-B07FA4B0A10E@me.com> Yes. You will then have to separate receivers in the K3, each with its own antenna. They can go to any band they wish, independently. The only limitation is the need for separate antennas. As an example, I have been monitoring VP8SGI on both 20 and 17meters simultaneously. 20m in my left ear, 17m in the right.

In many cases it produces dramatically improved blanking, at least in narrow-band modes (CW, PSK, FSK). I've been able to hear many weak signals that I simply couldn't hear before. It may also work for SSB signals in conjunction with a 15-kHz crystal filter, but I haven't tried that yet. The kind of noise I'm talking about is often quite unstable, with a buzzy sound, possibly drifting around a bit in frequency and amplitude. Light dimmers, switching power supplies, and various other devices create such noise. The noise may be narrowband: as you tune the VFO, you may find there's a "hump" of noise that's anywhere from 2 kHz to 50 kHz wide. It may also have very complex waveform with multiple noise pulses back-to-back in a burst. These types of noise are difficult to deal with. The IF blanker's signal path may be too wide (0.2 to 2 MHz), resulting in too little energy in-band to trigger the gating signal. The DSP blanker's RF signal path may be too narrow, making it hard for the DSP to distinguish noise from desired signal. * * * Setup: 1. Connect the radio to a computer running K3 Utility. Go into the Configuration / Configure Crystal Filter setup screen. 2. Find your 6-kHz filter (probably FL1 or FL2). Now the fun part: fake out the firmware by entering a bandwidth for this filter that's just 50 Hz wider than your narrow CW filter (ideally 250-500 Hz). *Do not* change the filter offset. But *do* make sure that the 6-kHz filter's CW and DATA enable boxes are checked. 3. Click "OK" to save this experimental crystal filter configuration setup. 4. You will now find that when the WIDTH control is rotated from, say, 0.40 to 0.45, the XFIL selection will jump from something like FL4 directly to FL1 or FL2 (your 6-kHz filter). That, hopefully, is the boundary where magic may occur, below. * * * The Experiment: 1. Find one of your most offensive local noise sources. I have them on most low bands. The stronger the amplitude the better. Narrowband sources may provide the most dramatic results. 2. Back down the AF gain control, then *turn off AGC*. You may need to use the RF gain to keep the signal from clipping. NOTE: The reason for doing this test without AGC is to make sure you can hear the full effect of applied noise reduction. AGC flattens out the receiver's audio response, making it hard to compare different settings. (If you find that the noise-remediation trick works, you can later turn AGC back on, and while the effect won't be as obvious, any benefit in signal-to-noise ratio will still apply.) 3. Select CW mode and adjust the WIDTH control for your narrow filter's bandwidth (example: "BW 0.40"). 4. Turn on the noise blanker (tap NB) and hold NB (LEVEL) to access the blanker parameters. 5. Set the IF blanker to OFF (VFO B). Then experiment with the DSP blanker settings (VFO A) to obtain the best possible reduction in signal. 6. While still the LEVEL parameters are still displayed, adjust the WIDTH control to the next step up (example: "BW 0.45"). This should kick in the 6-kHz filter, *but the DSP bandwidth and filter graphic will still show a narrow passband*. In other words, you're widening out the crystal filter but making very little change in the DSP's internal filter bandwidth (15 kHz IF, and AF). 7. Now re-optimize the DSP noise blanker settings for the 6-kHz filter case. Did the noise drop? (If you have a signal generator, e.g. an Elecraft XG3, you might put an antenna on it and generate a weak signal right in the middle of the noise to get more definitive results.) 8. Try it on other noise sources. It may help on some but not others, due to the wide variance in noise signals. Please log your results and report them to the list, at least until Eric shuts down the thread :) * * * IMPORTANT: As you can imagine, opening up the crystal filter bandwidth much wider than the DSP bandwidth will make the receiver more susceptible to in-band interference. If necessary, use RF GAIN, preeamp, and attenuator settings to reduce all interfering signals to a manageable level. I find there are many occasions on which better blanking is really critical, even if gain must be reduced in order to take advantage of it. * * * If we get enough positive responses from this experiment, we'll provide a simply, intuitive way of selecting the 6-kHz filter for noise blanking purposes. And maybe the 15 kHz filter for SSB use, if applicable. For example, we might add more selections to the DSP blanker parameter (presently t1-1 to 3-7).

Haven't tried it yet, so it's even more experimental. Still, if you're game, just set the bandwidth of the FM filter (always FL1, if it's present), to a bandwidth just a little over the bandwidth of your normal SSB filter. For example, if the SSB filter is 2.8 kHz, set the FM filter bandwidth to 2.9 kHz. Remember the caveat: Widening the filter will allow more in-band interference to slip through, which may require that you reduce gain (RF GAIN, preamp, or attenuator). AM and FM already use wide crystal filters, so the experimental technique I described will not offer any further improvement in these modes. It sure works well (for me, at least) in narrow modes.

(The idea is to blank out the noise, without blanking out a lot of the signal.) The wide filter passes the narrow noise pulses to the DSP, which can then blank them out like a hardware blanker. The result is passed to DSP bandpass filter. I don't have the 6 kHz filter, but I'd like to know how well it works. One of my (few) disappointments with the K3 is the noise blanker, which never seems very effective on line noise. The conventional noise blanker in my old FT-1000 can often reduce the noise dramatically, but only when there are no strong signals nearby. Alas, that means it never works during contests. Long, long ago, someone (Collins?) proposed using a second receiver to control a noise blanker, with the second receiver tuned to a nearby clear spot wide enough for a filter much wider than that of the primary receiver, say 15 kHz. That might be just outside the ham band, for example. Then the main receiver would retain its excellent immunity to strong nearby signals. Now, if the subreceiver in the K3/K3s could be made to do that, I'd buy the 15 kHz filter instantly. 73, Scott K9MA -- Scott Ellington K9MA Madison, Wisconsin, USA k9ma at sdellington.us From frantz at pwpconsult.com Thu Feb 4 00:27:31 2016 From: frantz at pwpconsult.com (Bill Frantz) Date: Wed, 3 Feb 2016 21:27:31 -0800 Subject: [Elecraft] K3S Computer Audio Question with Sub RX installed In-Reply-To: <019b01d15ee2$88f39660$9adac320$@carolinaheli.com> Message-ID: You need a way to separately decode both the left and right audio channels.

Woohoo. I was tuning around the bands, and I noticed birdies *everywhere*. Every 20-30Hz on 40m there was one -- and it was LOUD. I thought that something was up with my build, but then started doing an internet search for "K3 birdies". I saw one person (from a 2010 post on this list) note that the birdies could be coming from network devices (routers). A-ha! Initially, I thought it had something to do with my ASUS wireless router being extremely close to my operation location. I unplugged it, and the noise went away. Then I plugged it back in and removed, one by one, the connections to various devices (network storage, my shack computer, and the line that runs to my upstairs office). It just so happens that I had installed a network switch recently (produced by Linksys, and on sale at Best Buy last week). I unplugged the cable going to that switch, and the noise went away. I then plugged it back in, and went to the office and disconnected the power from the Linksys switch. Noise is gone again. So, I'm looking for a new network switch. Does anyone have advice on what has worked for them? Alternately, any idea on how to get the network switch from producing these awful birdies? I'm *not* looking for a new router -- but just a switch.

You NEED to use headphones to hear the difference because the cell recording has crappy audio. This test is done on 75 meters, dialed into a plasma TV generating noise. There is no intelligent signal present - just the noise floor and the plasma tv. In this test, I found that a DSP NB setting of 2-3 worked best - incidentally, is usually use 2-2 or 2-3 on a daily basis but I've never been really happy with any of the NB settings. Incidentally, I also tried it in the video with the AGC turned ON and that had good results, as well. I need to find an actual intelligible signal to do this on, but the preliminary results are quite impressive. I'd LOVE to have a DSP NB setting that would activate this without having to permanently alter the filter settings.

The technique described is suboptimal because you sacrifice the roofing filter function in order to narrow the blanker's passband. Is there some way to do this without interfering with the filters? My guess is that it would require a hardware modification. But maybe it could be a plugin replacement for the noise blanker board? Noise is a huge problem for many of us and it will only get worse in the future. Any improvement to anti-noise features would be a big advantage over the competition.

Light dimmers, switching power supplies, and various other devices create such noise. The noise may be narrowband: as you tune the VFO, you may find there's a "hump" of noise that's anywhere from 2 kHz to 50 kHz wide. It may also have very complex waveform with multiple noise pulses back-to-back in a burst. > > These types of noise are difficult to deal with. The IF blanker's signal path may be too wide (0.2 to 2 MHz), resulting in too little energy in-band to trigger the gating signal. The DSP blanker's RF signal path may be too narrow, making it hard for the DSP to distinguish noise from desired signal. > > * * * > > Setup: > > 1.

You can use a command-line argument to tell fldigi which configuration files to use You would run two instances of fldigi with different configuration files, one configured to use the left channel of a sound card on receive and the other configured to use the right channel of the same sound card. With this kind of setup there is no need for two sound cards. Programs like MMTTY that store their configuration information in a file in the program directory can also be used for dual receive. Simply set up two separate copies of the program in different directories, and then configure them to use the left and right channels of the sound card respectively. For basic dual RX receive that's all you need. Rig control and transmit capability add complications that depend on the specific hardware and software you are using. Note that if you want to be able to transmit on the VFO B frequency, both receivers must be in the same band. This is a transceiver limitation - the K3/K3S will not do cross-band transmit. 73, Rich VE3KI AE6JV wrote: > You need a way to separately decode both the left and right > audio channels.

It follows: "Personally, I don't want to "tinker" with 483 possible adjustments. As I've said before,with a radio with this much computing horsepower and the design talent at Elecraft I fail to understand why blanking thresholds and duration aren't nearly automatic. I would also like to see a technical description beyond the hand-waving in the manual of how noise blanking is performed. For example, I fail to see any dedicated delay in the signal path to create timing coincidence between the noise pulse and the blanking gate. Perhaps it's inherent in the design, but I would like to see some words that say so. If it's going to be necessary for me to set a blanking threshold (something I think could be automatic) then why can't the radio generate a blanking pulse that persists as long as that threshold is exceeded. Why do I also have to adjust that? If the pulse is so long that intelligibility suffers then that noise isn't amenable to being blanked and blanking needs to be disabled. The K3 blanker is okay. Although I no longer have it around to compare to, I designed a pretty effective one in 1977. Perhaps the best blanker I've run across was in a lowly Yaesu FT221R 2-meter multimode. The worst was in my TS870SAT that otherwise was a good performer and had great ergonomics. I've said more than once that Kenwood wasted panel space putting in a control for the noise blanker."

Light dimmers, switching power supplies, and various other devices create such noise. The noise may be narrowband: as you tune the VFO, you may find there's a "hump" of noise that's anywhere from 2 kHz to 50 kHz wide. It may also have very complex waveform with multiple noise pulses back-to-back in a burst. > > These types of noise are difficult to deal with. The IF blanker's signal path may be too wide (0.2 to 2 MHz), resulting in too little energy in-band to trigger the gating signal. The DSP blanker's RF signal path may be too narrow, making it hard for the DSP to distinguish noise from desired signal. > > * * * > > Setup: > > 1.

Now the fun part: fake out the firmware by entering a bandwidth for this filter that's just 50 Hz wider than your narrow CW filter (ideally 250-500 Hz). *Do not* change the filter offset. But *do* make sure that the 6-kHz filter's CW and DATA enable boxes are checked. > > 3. Click "OK" to save this experimental crystal filter configuration setup. > > 4. You will now find that when the WIDTH control is rotated from, say, 0.40 to 0.45, the XFIL selection will jump from something like FL4 directly to FL1 or FL2 (your 6-kHz filter).

AGC flattens out the receiver's audio response, making it hard to compare different settings.

I previously had a K3, so I am familiar with the menu and configuration. I configured the filters in the K3S as follows FL1 - 6 kHz FL2 - FL3 - 2.7kHz (-0.95 offset) FL4 - 700 Hz (+.04 offset) FL5 - 400 Hz I have tuned to a strong carrier (on CW) and then progressively narrowed my bandwidth. When I hit FL5, the audio is strongly attenuated. It basically disappears. I thought that something was wrong with my configuration, so I checked it again. FL5 was set for 400 Hz, which the filter in FL5 is. I performed several experiments. Choosing the filter with the XFIL button does the same thing. Audio is present with FL3 (2.7kHz) and FL4 (700Hz), but gone with FL5 (400Hz). Then, I went into the firmware and changed the bandwidth of FL5 to a narrower value (e.g. 250 Hz). I returned to listening to the audio and using XFIL produced the same results as before; however, when I tuned down from 700Hz to 400Hz, the audio was still there. When I went to 300Hz it was still there -- but it disappeared at 250 Hz (as I had set the filter's bandwidth in the firmware). Help! There's gotta be something simple but critical I'm missing...somewhere. Before you suggest it -- yes, I have tried to up the dB of the filter compensation for FL5 (400Hz). I increased it to the highest value, and the signal is still basically gone -- but maybe slightly higher. -john NE4U From jdwalkerjr at aol.com Thu Feb 4 10:41:30 2016 From: jdwalkerjr at aol.com (James D.

From my experience with radios on the desk, past and present, the hardware noise blanker works quite well. On the other hand, DSP/software noise blankers have always been found to be marginal. It seems we are insisting on tighter and tighter bandwidths {filters} to fight QRM. While at the same time, the use of a tighter the filter has the adverse effect that causes the noise pulse to be fattened. This is what Wayne was discussing in his recent post. In another approach, use a wide filter ahead of the NB thus it can become more effective on blanking. Wide pulses when blanked will punch holes in the audio. There's a lot of history with Collins Radio and the implementation of noise blanking methods. None of these use DSP schemes and in one system, a separate antenna was used to feed noise pulses to the blanker circuit. I suggest one research the topic in this vein. One of my current radios on the desk uses a hardware noise blanker while the other one uses a DSP/software blanking system. Both radios are from the same company. It is amazing how much better the hardware noise blanker performs over the two radios which use DSP or software noise blankers. 73 Bob, K4TAX K3S, s/n 10163 On 2/4/2016 8:45 AM, Wes (N7WS) wrote: > Maybe this is an opportunity to rant about the K3/K3S noise blanker. > > Back on 12/8/15 K2AV wrote: "To those trying to get rid of a certain > noise, remember that there are 21+21+(21x21) combinations of IF and > DSP blanking.

My units are the full size K3/0s, so it's unlikely any low pass filtering is in place. I checked the continuity between pin 1 of the 8 pin front mic connector and the tip connection on the rear mic connector and found they are tied together measuring less than 10 ohms. The very fine traces on the circuit board might account for this resistance. Sadly no schematic or board layout is available to confirm. The PTT from pin 2 on the 8 pin mic connector also checks to be directly connected to the rear PTT RCA jack. So this tells us the "local" K3/0 settings do nothing to change the mic audio. I also determined the problem is a ground loop where noise from the RRC control unit is being picked up by the interconnecting mic leads. After adding further ground loop isolation directly at the rear 1/8 mic jack with a 600/600 ohm transformer removes all the noise. This might have been my final solution but you cannot pass DC mic bias through a transformer if you need it. But next the real answer! Close inspection of the "factory" AUX/MIC cable from Remoterig shows no conformity to the schematic provided in the manual! The cable provided is a lengthy CAT5/6 4 pair cable with short breakouts at the end with the PTT RCA connector and 1/8" mic connector. This factory cable is unshielded. Wires used for mic audio and mic return are from separate pairs, not from one twisted pair. Consequently, shielding is close to non-existent. PTT wiring is similar. Making up my own cable with longer shielded wires connected to a very short piece of CAT 5/6 at the RJ45 works much better! Leaving a long length of exposed mic cable is not good practice. This may work OK with high level signals but is a no-no for low level mic signals. A shielded piece of CAT 5/6 might also work. 73, John W1AN -- View this message in context: http://elecraft.365791.n2.nabble.com/Is-K3-0-Audio-pass-through-or-processed-in-K3-0-tp7613427p7613521.html Sent from the Elecraft mailing list archive at Nabble.com.

This has to do with Macros and command sequences used to program or alter some specific setting in a temporary (maybe) way. Many of these are posted here as well as found on some web sites including Elecraft. But, there is something missing that would be nice. And, that is a documented library hosted on Elecraft?s web site as well as a utility program feature to automatically download and manage the macro programs. As a library, the documentation should be embedded in the Macro file itself per a standard format that declares the purpose (brief abstract), more detailed user instructions, and any known side effects. Also, author?s name and date and maybe a revision history. The utility programs would include a new feature to download (maybe abstracts or complete macro file) and list available macro programs displaying the brief abstract on the display. The utility program would allow the user to select macros for download that copy them to a known location on the user?s computer managed by the utility program. Also, this new feature set would support the loading of the macro to the K3/K3S/KX3. Actually, a very nice ?extra? would be to undo the macro act. Of course, this could get complicated since a Macro can do anything and many things that should not be done. But, one way to undo is to automatically save and then allow restoration of the rig settings, say in some kind of test mode. Of course, this could be done by the user but it might be faster to do it as part of a test sequence supported by the utility program. It seems like the only complicate part of this process is setting up a repository and managing it in a way that ensures the integrity of the standards: documentation, layout, and anything else. The enhancements to the utility programs do not seem to be all that hard to do (I am a retired programmer of about 50 years programming experience). There could be a network of volunteers that accept the new macros to be included and they test and vet those macros per the definition of purpose and the standards set forth for this repository. 73, phil, K7PEH From rpfjeld at outlook.com Thu Feb 4 12:19:09 2016 From: rpfjeld at outlook.com (Richard Fjeld) Date: Thu, 4 Feb 2016 11:19:09 -0600 Subject: [Elecraft] Fwd: Re: P3 TX MON envelope display In-Reply-To: References: Message-ID: From billamader at gmail.com Thu Feb 4 12:24:10 2016 From: billamader at gmail.com (Bill Mader) Date: Thu, 4 Feb 2016 10:24:10 -0700 Subject: [Elecraft] Elecraft Digest, Vol 142, Issue 4 In-Reply-To: References: Message-ID: <0b0801d15f70$dc971600$95c54200$@gmail.com> Great advice Fred! I use K3_Ez and the K3 Utility to save, then modify, and then retrieve configurations. I experienced a problem for a long time that I corrected using this approach. For some reason, when using N1MM+ (or its previous version), my Mic Gain would intermittently go to zero after invoking any one of the DVR memories. I "assumed" it was an N1MM+/K3 anomaly. I ran into one other ham who experienced this too. It turns out, when I re-loaded the out-of-the box K3 configuration, the problem finally disappeared, or at least it hasn't re-appeared. If a computer is involved (including firmware), always back-up to save configurations (data) because you will likely need that back-up someday. I keep K3_Ez available at all times. I can quickly change the TX equalization with a mouse click or two. Now that I have the Genovation keyboard, I will likely dedicate a couple of keys for this purpose. 73, Bill, K8TE ------------------------------ Message: 14 Date: Wed, 3 Feb 2016 14:12:25 -0800 From: Fred Jensen To: elecraft at mailman.qth.net Subject: Re: [Elecraft] help with improving transmit eq Message-ID: <56B27B49.2040000 at foothill.net> Content-Type: text/plain; charset=utf-8; format=flowed I'm thoroughly convinced that I'm as bright as I'm ever gonna get. :-) I followed Jim's advice for both RX and TX EQ after wasting a whole bunch of time trying to figure it out myself [see first sentence above].

Message-ID: <027701d15f80$b682e7e0$2388b7a0$@net.nz> Greetings fellow Elecrafters, Being very interested in Wayne's initial comments regarding his experiments, and because I share his noise problems here; I've had an initial play. A brief summary of my initial results are as follows: I was copying VP8SGI on 10110KHZ around about 1000UTC- they had a very fluttery polar signal on a rather "hissy" band with the usual bursts of QRN as well. (Both VP8STI & VP8SGI are very difficult for us ZLs, as it's a bad polar path...) I'd faked my 6KHz filter to operate at 300Hz width, and it did help quite a bit with the NB activated, to clean the signal up. For me, the sweet point seems to be t2-6, and the readability of the signal was much improved over using my 400Hz filter at 400Hz width, with or without noise blanking or noise reduction. I also listened to some poor signals on 40 metres in the VP8's pile up there, and found exactly the same results. In fact, some signals were improved from being audible but barely readable to being quite good copy, and again, t2-6 seemed to be best. On 80 metres this morning, digging out the Europeans at the bottom of the band, t3-2 seemed best. I'll continue to play, it's certainly worth investigating further, even if it does mean tweaking the NB setting from time to time. I don't mind tweaking a knob or two if it lets me notch up a new one. 73, Tony, ZL2AGY.

If you hit it with 1500w it might survive, but that will cause a couple of low power resistors to dissipate up to 35W, so they might be in danger of failing. Note that the 2000W coupler is good down to 1W and is what I use for all my operating, QRO or QRP. The 200W coupler is good down well below a watt, for those who like to go even lower..

The antenna in question is a simple 75 meter dipole fed with coax. You tune the antenna at 3922, 2955 and 3975 - just for example. When you return to those frequencies, a few hours later, the tuning is all off and the KPA500 demos its displeasure by beeping and flashing lights. Retuning will again hold for a few hours, then all goes haywire again. I have given shake test to the antenna/halyards - with an analog SWR bridge in line - and see nothing to indicate breaks or damage. I replaced the feed line and it still does everything the same. All coax lines inside have also been changed out - to no avail. I should mention that this problem exists on an alternate antenna also. The alternate is also a dipole type. No remote baluns, nothing other than simple center insulators. Chances are they are built properly - been doing it for over 55 years and have never experienced anything like this. I have reset the KAT500 to default a couple of times - reinstalled the software - all the things you do with black boxes - went through the training thing. I spoken with Elecraft and followed their instructions to the letter also (which were the same as what I had been doing). It all holds well for a few hours, then goes wacko. If I have to push the buttons every time I QSY, there is little reason to continuing using the KAT500. Of course that makes using the KPA500 more difficult or impossible. Shipping is expensive and so are service charges - the tuner is way out of warranty. Anyone have experiences such as these or suggestions? I am seriously considering regressing to a manual tuner.

Keep in mind that a 1:1 balun is really just a length of feed line, usually wound on a toroidal core to make the required length shorter than if it was in open air. The "old-school" baluns were just a pair of air wound coils. If your balanced feed line is at least 1/4 wavelength long, the currents will be "balanced" (equal and out of phase) at the antenna. That assumes your antenna is perfectly balanced to provide a perfectly balanced load, which "balanced" antennas almost never do. There are just too many variables. So expect excellent results even with shorter feed lines. The amount of radiation (or pickup) from the feed line even at the rig end is small in any case. Connect one side of the open wire feed line to the KAT100 SO-239 center pin and the other to the KAT100 ground terminal. 73, Ron AC7AC -----Original Message----- K2/100 and KAT100 here.

And for open wire fed antennas: http://www.dj0ip.de/open-wire-fed-ant/ To answer your question, a high power 1:1 current balun is likely best. Of course you could built a balanced tuner as I did. Problem solved. That's another story. Keep in mind that balun power ratings are for "matched" conditions. Which in fact is never the case with a center fed wire and open wire or a balanced feed line. At a mighty 5 watts it would not be of concern. If at all possible, run the balanced feed line from the antenna feed point all the way to the operating position. Keep the coax run between the tuner output and balun input as short as practical. After all, the reason to use balanced feed line is to take advantage of the low loss properties. Never fear, the use of balanced feed line is not near as critical or fussy as the "masses" will so tout. Many hams express fear in using balanced feed systems, largely because of what they have heard. Mostly because it frankly isn't fact. Mine feeds a 256 ft center fed wire and comes down the tower supported on home made 9" PVC stand-offs, through the attic eve vent, across the roof rafters, and drops down through the ceiling to the tuner on the shelf above the desk. Not bad for a 160M - 10M antenna. {see my pix on QRZ.COM that shows a bit of the line going up the wall.} 73 Bob, K4TAX On 2/4/2016 2:55 PM, Jim Allen wrote: > K2/100 and KAT100 here. > > I am changing around my modest antenna configuration now.

I have scoured Rick's website for some time, on this and other topics, and corresponded with him extensively about various ideas. I've also read dozens of web pages about baluns, any number of threads at QRZ.com on the topic as well. There are confusing, contradictory and often mutually exclusive points of view and no clear direction how to go for those of us whose understanding of these things is fairly shallow. Each approach has disadvantages, detractors and claimed limitations, it seems. I could easily make a balun with a ferrite toroid core, as shown by G3TXQ with 10-12 turns of some RG8x, which I have in hand, pop it in a box with a couple of connectors, and have a go with that. I am sensitive to losses, since with QRP and modest antennas due to external limitations, I have no dbs to waste. I need to have one, or two, good multi band antennas. I try to avoid store bought antennas, and anything with radials are a no-go here on the Rock Ranch.. I just started using the KAT100. Pretty slick. With a good quality balun, it has some attractive features, replacing the AH-4. I have also been tempted by the MFJ974HB balanced tuner. No balun needed but no KAT100 needed either. I wish I could find the parts to roll my own! I have been using balanced feed lines for the various antennas since I moved here ~30 months ago with gratifying results. Keep the suggestions coming! 73 de W6OGC Jim Allen Message: 23 Date: Thu, 4 Feb 2016 17:10:39 -0600 From: Bob McGraw K4TAX To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Balun suggestions Message-ID: <56B3DA6F.3090208 at blomand.net> Content-Type: text/plain; charset=windows-1252; format=flowed As one that has personally used a balanced fed antennas for years, I suggest you review the info on this site. http://www.dj0ip.de/balun-stuff/ Good stuff on evaluating or building a proper balun. And for open wire fed antennas: http://www.dj0ip.de/open-wire-fed-ant/ To answer your question, a high power 1:1 current balun is likely best. Of course you could built a balanced tuner as I did. Problem solved. That's another story. Keep in mind that balun power ratings are for "matched" conditions. Which in fact is never the case with a center fed wire and open wire or a balanced feed line. At a mighty 5 watts it would not be of concern. If at all possible, run the balanced feed line from the antenna feed point all the way to the operating position. Keep the coax run between the tuner output and balun input as short as practical. After all, the reason to use balanced feed line is to take advantage of the low loss properties. Never fear, the use of balanced feed line is not near as critical or fussy as the "masses" will so tout. Many hams express fear in using balanced feed systems, largely because of what they have heard. Mostly because it frankly isn't fact. Mine feeds a 256 ft center fed wire and comes down the tower supported on home made 9" PVC stand-offs, through the attic eve vent, across the roof rafters, and drops down through the ceiling to the tuner on the shelf above the desk. Not bad for a 160M - 10M antenna. {see my pix on QRZ.COM that shows a bit of the line going up the wall.} 73 Bob, K4TAX Sent from my iPad From jtmiller47 at gmail.com Thu Feb 4 19:51:40 2016 From: jtmiller47 at gmail.com (Jim Miller) Date: Thu, 4 Feb 2016 19:51:40 -0500 Subject: [Elecraft] Balun suggestions In-Reply-To: <56B3EF1D.4010702@embarqmail.com> References: <52D8BB1A-8E2F-4CBE-8410-5BBAB60B4851@gmail.com> <004401d15f98$29351f30$7b9f5d90$@biz> <56B3EA1A.7020801@triconet.org> <56B3EF1D.4010702@embarqmail.com> Message-ID: <4724E0DF-C70B-4765-BE4B-29C89256C9B7@gmail.com> I suggest reading work by w9cf before getting concerned about balancing tuners. http://fermi.la.asu.edu/w9cf/articles/balun/index.html On Feb 4, 2016, at 7:38 PM, Don Wilhelm wrote: Wes, I don't mean to be contentious, but under ideal conditions, what Ron said is true.

Message-ID: <1454634261772-7613568.post@n2.nabble.com> I thought I would try VP8SGI this evening on 40M, since I had not tried 40 due to the horrible DQRM almost every night on their TX frequency. They were pretty loud tonight here in NTx (10-15 dB above noise floor). I use a Delta Loop at 50 feet. A DQRM was "almost" zero beat on their frequency and 20 to 30 dB louder than them, making it near impossible to copy them. And to top it off, there were also a few signals very near their Tx frequency also. I cranked the K3 filter down as far as it would go (50Hz) and tuned the VFO A just ever so slightly to maximize the SGI copy and throw a few dB more rejection on the DQRM. After a few seconds, I could copy him clearly to make the contact. This was the first time I have had to use that much filtering to make a contact! ----- Roger W5RDW -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-in-Very-Heavy-DQRM-on-40M-CW-tp7613568.html Sent from the Elecraft mailing list archive at Nabble.com.

I almost always run 5 watts, all CW You didn't say what your antenna is or what bands you want to work. Antennas, feedlines, and tuners are a SYSTEM, and must be considered as a system. Why do you want to use "balanced" line? Has someone told you it's lower loss, and you can use any random wire (or some "magic" length of wire on all bands? Are you trying to use a non-resonant antenna on multiple bands? If so, why? Is that the only sort of antenna you can hang? There are serious issues with this sort of antenna. First, there can be significant feedline losses. Second, these antennas are nearly impossible to choke to kill common mode noise, so they can be noisy. Off-center-fed antennas are unbalanced by their nature, so they're inherently noisy. Even a center-fed antenna will be unbalanced by its surroundings -- sloping ground, variable height, proximity to other conductors on one end but not the other, etc. Take a look at the antenna planning tutorials on my website. All of the options shown there are superior to most "all-band" wires. 73, Jim K9YC From wes at triconet.org Thu Feb 4 23:42:41 2016 From: wes at triconet.org (Wes (N7WS)) Date: Thu, 4 Feb 2016 21:42:41 -0700 Subject: [Elecraft] K3/K3S noise blanker performance greatly enhanced (at my QTH) -- need testers In-Reply-To: References: <8C1A61DA-B2A4-46E0-9321-896FE8579C3D@elecraft.com> <000301d15f7f$0f8d7870$2ea86950$@windstream.net> <1454628590892-7613554.post@n2.nabble.com> <56B3E2EE.40106@blomand.net> Message-ID: <56B42841.6010209@triconet.org> It's called topic drift.

The characteristics of a pulse that can be blanked are: 1) its amplitude is sufficiently greater than the desired signal so it can be detected as undesired (noise) 2) its duration isn't so long that the "hole" punched in the signal appreciably degrades intelligibility. Note that *one* pulse is all that is needed. A repetitive pulse train that satisfies 1) might not satisfy 2, if the pulses are too close together. Conversely, totally random pulses can satisfy both 1 and 2. Now in common ham lingo, what you say is true: "repetitive noise" is something like ignition noise and "random noise" is static crashes or the like, so those terms meet my previously stated criteria.

Sorry, that is NOT the definition of "balance." Balance is defined by equal potential to the reference plane, which for most land-based antennas is either the earth or the chassis of the transmitter that feeds it, which is usually ground referenced. > Consider the currents between the center conductor and the inside of > the shield for coax. They must be equal and opposite. It is the > common mode current on the outside of the feedline that produces any > unbalance. No, the common mode current is the RESULT of imbalance. AND -- common mode current is present in two-wire feedlines when the antenna or the transmitter is unbalanced. In those 2-wire feedlines, common mode current is the DIFFERENCE between the current in the two conductors. Note also that feedlines have wavelength, and both voltage and current vary along the line. The DIFFERENTIAL voltage and current vary as a function of the behavior of the line as a transmission line, with Vf being that of the line. The COMMON MODE voltage and current vary along the line as a function of the line's behavior as an ANTENNA, where Vf is determined by the insulation on the outer conductor(s), so is 0.98 - 0.99. I laugh at those who attempt to measure current in both sides of a 2-wire line and think that what they have measured is the current at every point on the line. It is not -- it's only the current at the point you measured it, and it's only right there if your measurement technique is without error. Which ain't easy. 73, Jim K9YC From ab2tc at arrl.net Fri Feb 5 02:13:07 2016 From: ab2tc at arrl.net (ab2tc) Date: Fri, 5 Feb 2016 00:13:07 -0700 (MST) Subject: [Elecraft] VP8SGI In-Reply-To: <0590A50C79AE417A8450ED883A5C95A4@LAPTOPEPVQLR1I> References: <954F806165404283996E41F98922580C@LAPTOPEPVQLR1I> <0590A50C79AE417A8450ED883A5C95A4@LAPTOPEPVQLR1I> Message-ID: <1454656387008-7613582.post@n2.nabble.com> Hi all, Darn, I must have missed them.

Another benefit for digital modes is being able to receive THE SAME signal (frequency) but through two antennas with two receivers, two digital programs (can be the same program twice or dissimilar apps), two decoder filters - improving your chance of solid signal decoding under marginal conditions.

You can use a command-line argument to tell fldigi which configuration files to use You would run two instances of fldigi with different configuration files, one configured to use the left channel of a sound card on receive and the other configured to use the right channel of the same sound card. With this kind of setup there is no need for two sound cards. Programs like MMTTY that store their configuration information in a file in the program directory can also be used for dual receive. Simply set up two separate copies of the program in different directories, and then configure them to use the left and right channels of the sound card respectively. For basic dual RX receive that's all you need. Rig control and transmit capability add complications that depend on the specific hardware and software you are using. Note that if you want to be able to transmit on the VFO B frequency, both receivers must be in the same band. This is a transceiver limitation - the K3/K3S will not do cross-band transmit. 73, Rich VE3KI AE6JV wrote: > You need a way to separately decode both the left and right > audio channels.

Woohoo. I was tuning around the bands, and I noticed birdies *everywhere*. Every 20-30Hz on 40m there was one -- and it was LOUD. I thought that something was up with my build, but then started doing an internet search for "K3 birdies". I saw one person (from a 2010 post on this list) note that the birdies could be coming from network devices (routers). A-ha! Initially, I thought it had something to do with my ASUS wireless router being extremely close to my operation location. I unplugged it, and the noise went away. Then I plugged it back in and removed, one by one, the connections to various devices (network storage, my shack computer, and the line that runs to my upstairs office). It just so happens that I had installed a network switch recently (produced by Linksys, and on sale at Best Buy last week). I unplugged the cable going to that switch, and the noise went away. I then plugged it back in, and went to the office and disconnected the power from the Linksys switch. Noise is gone again. So, I'm looking for a new network switch. Does anyone have advice on what has worked for them? Alternately, any idea on how to get the network switch from producing these awful birdies? I'm *not* looking for a new router -- but just a switch.

Twin feeder happily supports both differential (equal and opposite, balanced) currents and common-mode current at the same time. So, in the real world, there is no such thing as "balanced" feedline unless YOU actually DID something to FORCE it to be balanced. And the way to do that is to insert a common-mode choke that enforces equal-and-opposite currents at that particular location... though even then, it can do nothing to prevent the regrowth of common-mode current elsewhere along the line. 73 from Ian GM3SEK -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Wes (N7WS) Sent: 05 February 2016 00:18 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Balun suggestions I just pinched myself; I'm not dreaming and it's not April 1st, so I guess you're serious.

There are a LOT of CAT-5 and CAT-5e labels on cables out there that simply aren't. There's a list of specs involved, fairly lengthy one, all of which must be met to qualify a cable at a specific grade. Most cables that fail a check because they missed something in the termination procedure (not signal routing). ______________________ Clay Autery MONTAC Enterprises (318) 518-1389 On 2/5/2016 3:48 AM, Larry Gauthier (K8UT) wrote: > John, > > I had a similar situation here with a LinkSys switch.

If the problem is not present, you can blame it on RF-in-the-shack being picked up by the audio input or your computer. If you do have an RF problem, the cure is in the antenna field.

The power level bars indicate exactly where I set the pwr at....looks to me like the KX3 will display then set pwr when you start transmitting in JY9/65 and, if you touch the pwr knob after you start transmitting the KX3 display your ALC setting.....just sayin'!!!

My experience with APF is that it will indeed pop a signal that is already copyable, if a bit weak, out of the noise. Makes for easier copy. However the ringing is so bad on a really weak signal that it is of no help. I guess it depends on what you view as 'weak' and your noise level. I was hoping it would make previously un-copyable signals copyable, but that does not happen. Instead it improves the copyability of weak but already copyable signals. I find that simply narrowing the filters to 50, 100, or 150 Hz will give essentially identical results as using the APF and is much easier to do. As for the super critical tuning, I do not find it to be all that critical. The signal can be improved somewhat by going to the 'fine' tuning, but it makes only a small difference. 10 Hz steps are OK and much quicker. The APF has a BW of about 30 Hz so tuning cannot be all that critical. +/- 5 Hz out of 30 is not that big of a deal. This has been one of my biggest disappointments with the K3. After reading all the hype about APF I was hoping for a real improvement. But does not happen. OTOH, the narrow filters of the K3 are outstanding. 73 de dave ab9ca/4 On 2/5/16 8:53 AM, David Kuechenmeister wrote: > I tried this the other day with no success.

Wayne told me there had been no change in code, but I have never understood that.

Most hams seem to use excessive RF Gain which will force noise through the filter and all of those undesirable artifacts will be heard. If in doubt, reduce the RF Gain. Using this technique, I can tune the band with the APF engaged, adjusting the RF Gain a bit, and actually hear signals with this configuration which without the APC no signal could be heard. I view this gives one the ability to actually "dig signals out of the noise". 73 Bob, K4TAX On 2/5/2016 9:56 AM, dave wrote: > > I'd agree.

I am citing the definition upon which IEC and AES Standards are based, which are established by international bodies of first rate engineers. I'm a member of the AES Standards Committee. It may come as a shock to some, but almost everything fundamental about electricity, electronics, audio, radio, and transmission lines was well understood and documented nearly 100 years ago, and much of it decades earlier. There's a slide presentation on RFI on my website that addresses the topic of balance.

I have mostly tried APF at times of high lightning activity. I think we in the SE get more of that than other parts of the country. The higher noise level means more weak signals. You need all the help you can get. But that noise differs from the usual band noise. And it may depend on each individual's hearing.

If you have a roofing filter in that range stay within it. Turn on NR set to mF5-3 or there about. The wide BW helps the NR work well. The "mix" mode lets a little unprocessed signal+noise through. This is a good weak signal search mode. When you find a signal you want to copy, turn on APF and peak it in the filter. Fine tuning helps. There is little ringing because NR has reduced the noise amplitude. You can decrease the DSP BW a little but the NR is more effective with uncorrelated noise. This technique has gotten me many pelts in the QRP Fox Hunts. 73, Brian, K0DTJ From rcrgs at verizon.net Fri Feb 5 11:57:49 2016 From: rcrgs at verizon.net (Robert G Strickland) Date: Fri, 05 Feb 2016 16:57:49 +0000 Subject: [Elecraft] K3/K3S noise blanker performance greatly enhanced (at my QTH) -- need testers In-Reply-To: <8C1A61DA-B2A4-46E0-9321-896FE8579C3D@elecraft.com> References: <8C1A61DA-B2A4-46E0-9321-896FE8579C3D@elecraft.com> Message-ID: <56B4D48D.4080905@verizon.net> My widest filter is 2.8MHz [the optional, 8-pole ssb filter].

Light dimmers, switching power supplies, and various other devices create such noise. The noise may be narrowband: as you tune the VFO, you may find there's a "hump" of noise that's anywhere from 2 kHz to 50 kHz wide. It may also have very complex waveform with multiple noise pulses back-to-back in a burst. > > These types of noise are difficult to deal with. The IF blanker's signal path may be too wide (0.2 to 2 MHz), resulting in too little energy in-band to trigger the gating signal. The DSP blanker's RF signal path may be too narrow, making it hard for the DSP to distinguish noise from desired signal. > > * * * > > Setup: > > 1.

You will now find that when the WIDTH control is rotated from, say, 0.40 to 0.45, the XFIL selection will jump from something like FL4 directly to FL1 or FL2 (your 6-kHz filter).

I used the 13kHz filter because it was in my K3. DSP 2-3 or 3-3, IF Blanker OFF. The main improvement is on the DSP blanker, the hardware blanker remains only mildly effective on strong electric fence pulses and is little use if any with FL1. Some overload on strong signals as expected because of wide roofing filter. Setting the bandwidth to activate either my 500 and 200 filter each side degrades NB performance to previous. I will try with a 6kHz filter in due course.

Rob Sherwood has had a lot to say about this. Elecraft has taken steps to minimize the effect. Yes different types of noise clearly have different characteristics and thus the reason for suggesting reducing the RF Gain, it reduces the noise. Fortunately this time of year in our location in TN the noise is quite low, unless a line of thunder storms is located within 500 or so miles. Hear this morning no thunder storms close by, the neighborhood is reasonably quiet, and the noise on 40M is about -103 dBm. With the APF a signal at -113 dBm can be easily copied, yet without the APF nothing but noise is heard. My technique is to observe the S meter, no signal, RF Gain at max for the given band and antenna. Then with the antenna disconnected, actually by a switch, I adjust the RF Gain until the S meter indicates the same value as the noise coming in on the antenna. Then switch the antenna back to the receiver. Also the AUTO SPOT feature is a big aid to optimum tuning. The result is signal present and no noise. 73 Bob, K4TAX On 2/5/2016 10:49 AM, dave wrote: > >> one must also discover the >> artful use of the RF Gain control as well > > Adjustment of the RF gain control is not mentioned in Wayne's note on > using APF. > > When I tried it here, the RF gain might have made some small > difference but it still did not allow un-copyable signals to be > copied.

Just for fun I tried tuning some of the same VP8SGI signals on a Drake 2B/2BQ and found adding the 2BQ in the mix more user friendly and making a bigger difference, but hey, the 2B was starting from a worse spot. Still it would be nice if the APF was user adjustable like the 2BQ or the old outbaord audio filters, peak magnitude, and maybe even frequency, within a selected passband. Not sure why Wayne picked only 3 db - I'd like it to be user adustable to try a bit more peak if conditions permit. If APF is user adjustable in that way and I missed it somebody please point out the page number....or if the experiment's been done and it's not workable would like to know that too. 73 Scott ka9p In a message dated 2/5/2016 11:08:53 A.M. Central Standard Time, ho13dave at gmail.com writes: > one must also discover the > artful use of the RF Gain control as well Adjustment of the RF gain control is not mentioned in Wayne's note on using APF. When I tried it here, the RF gain might have made some small difference but it still did not allow un-copyable signals to be copied. When testing APF I have made all adjustments the I thought might affect signal quality. IIRC correctly I also tinkered with the AGC parameters. But the APF never produced results any better than simply narrowing the filters. Usually the regular narrow filters worked better. I know I had not switched APF on for months. I did switch it on to recheck before sending my note. But the noise is not currently high enough to give it a good test. I have found, in general, that careful adjustment of the RF gain control can be useful. This applies to all receivers I have tried it on. I'm wondering if the difference is in the type of noise. I have mostly tried APF at times of high lightning activity. I think we in the SE get more of that than other parts of the country. The higher noise level means more weak signals. You need all the help you can get. But that noise differs from the usual band noise. And it may depend on each individual's hearing. I have always puzzled over why some rave about how great APF is while for myself, and obviously others, it is of no help at all. 73 de dave ab9ca/4 On 2/5/16 10:13 AM, Bob McGraw K4TAX wrote: > While I find the APF works really nice, one must also discover the > artful use of the RF Gain control as well.

Set up as described, only using a 13KHz filter in F1 position... ? Using a florescent light, which makes a rather ugly wide band noise, only on 18 MHz., I performed a sort of blind test.... ? After doing the full setup as you described on a very weak CW station, I hit the NB button as fast as I could for several seconds while looking away from the radio... ?This confused me as to if it was on or off... I then while still looking away from the radio brought the NB on and off line, and stopped on teh CW that was easiest to copy. ? I did this five times, and after each test, I re-scrambled my memory by again, hitting the NB switch many times, and looking away from the radio. ? Five out of five times the NB was off when I stopped, indicating that the NB made the CW harder to copy. ? Sorry... ?I will try later tonight, when all the Horticultural lights come on line on 40 meters, which has tons of RFI from them. ?I will report again... -- 73's, and thanks, Dave For software/hardware reviews see: http://www.nk7z.net For MixW support see: https://groups.yahoo.com/neo/groups/mixw/info For SSTV help see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Wed, 2016-02-03 at 19:03 -0800, Wayne Burdick wrote: > Hi all, > > If you have... > > - really ugly noise sources that neither of the K3/K3S noise blankers > completely clean up, and? > > - a 6-kHz crystal filter, and > > - a narrow crystal filter (200-1000 Hz) > > ...then you may want to try an experimental technique I've been using > the past couple of days.

I went with linsys AE1200s which were on sale cheap from an Amazon partner. My only regret is that linksys, oddly, does not have linux drivers for this dongle. If you don't plan on using linux not a problem. I also put the wireless router, an SMC wireless G, at the other end of the house. I gave away an Apple Airport as even at the other end of the house it spewed all kinds of trash, annoying on 80 and 30M. Switches in the shack are likely to be noisy and their noise may propagate via the cables if you put them elsewhere. Wireless G is plenty fast unless you do a lot of file xfer between computers. You might also want to lay on a good stock of 31 material toroids with 1.5" or better IDs so you can wind rig cables at both ends. I have found USB cables to be a pipeline for RF into and out of PC and rigs. So I use a 2 port PCI serial card from StarTech for rig cat to K3 and IC7000.

Several of us lobbied for an APF feature shortly after the K3 debuted in 2007, drawing on our experiences with the FT-1000D. There /were/ two firmware versions that Wayne developed, and the consensus among some of us was that the first one was better than the second. As I recall, the second version cleaned up some artifacts and unintended consequences, but, we felt, at the cost of diminished "peaking." Wayne was adamant that the APF part of the code was not touched. We eventually chalked up the difference between the two versions to subjectivity among the testers and left it at that. Barry, by the way, is also correct in saying there were two versions of the APF circuit in the FT-1000D over the years. It has been the consensus of owners that the earlier version was superior to the later version. The APF in both the K3 and KX3 is excellent, in my opinion. 73, Kent K9ZTV K3/KX3 s.n. 21 On 2/5/2016 10:03 AM, Stephen Prior wrote: > I've seen it written that it helps to offset the IF slightly, although to > be honest I have never myself got the APF to work to my satisfaction. > Oddly, and I communicated with Wayne about this at the time, the first beta > (I think) implementation of it was stunning, but a later release lost it > for me.

This release includes two new features: The new 15-watt level applies only to 80-20 meters, and is still considered somewhat experimental. Several dozen field testers have been using it with excellent results, but we can't guarantee that every KX3 will actually put out a full 15 W. Supply voltage is one limiting factor. We strongly recommend the use of 13.8-14 V whenever possible. This is especially important when you're driving an external amplifier and using one of the linear modes (SSB, AM, PSK-D, or audio data modes). PSK63 is twice as fast as PSK31. Rather than copy it on the KX3's VFO B display, you may want to use the Terminal function of KX3 Utility, or use a PX3 with text decode turned on. This data mode is especially popular in Europe. Rev. 2.38 also corrects a problem with some KX3-4M (70 MHz) modules that had lower than normal power output. 73, Wayne N6KR * * * MCU 2.38 / DSP 1.37, 01-03-2016 . POWER OUT NOW 15 WATTS MAX, 80-20 M: On 80-20 meters, the PWR control can now be set as high as 15 W (max is still 12 W on other bands). Supply voltage must be over 12.8 V on key-down as indicated by the KX3's voltage display (tap DISP, rotate VFO B). Note: The KX3 will automatically reduce power as required if current, SWR, or temperature is excessive, or if supply voltage is too low. If a band other than 80-20 m is selected, power output will be cut back to 12 W max. It must then be manually set above 12 W after switching to 80-20 m. . PSK63 MODE ADDED: Tap DATA, rotate VFO B until PSK D is displayed, then use VFO A to select 31 or 63 baud. The default is PSK31. . 4-METER POWER OUTPUT IMPROVED: Changed IF band-pass filter configuration to increase drive level on 4 meters. This should improve 4-meter power output in cases where it was marginal due to filter rolloff. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to ki4d at arrl.net From Gary at ka1j.com Fri Feb 5 16:16:16 2016 From: Gary at ka1j.com (Gary Smith) Date: Fri, 05 Feb 2016 16:16:16 -0500 Subject: [Elecraft] K3 - Most desirable form of AK3 to sell Message-ID: <56B51120.4641.19633676@Gary.ka1j.com> I love my K3, nothing wrong with it in the least and it works exactly as I expect it to.

So the decision I have to wrangle with is what to leave in my old K3 and what to migrate in my K3, over to the K3s. Do I want to leave in the 100W or move that to the K3s, the internal tuner? leave it or migrate? The new synth board... & so on. It seems like the K3/100 is more desirable selling-wise than the K3/10 but what is the advantage in selling price if I leave the tuner in the K3 as considering the selling price?

I have an inverted V antenna with the peak at about 12 meters (44'). When I started, I could barely hear him. When I got the APF tuned in, I could hear him clearly, and actually managed to work him with 100W. I had to send my call 5 0r 6 times before AA7A, the op on the other end got it, but I could easily hear when he got it. To pull me out of the muck means he must be really good. When it worked well for me, there were no signals near the DX, and it worked with less ringing than going to a 50 Hz DSP bandwidth. I find when the CW gets up above about 25 WPM, the ringing makes it more difficult to interpret, although honestly, 30 WPM is well above my CW speed of competency. 15 is more like it for English text (W1AW practice). On the other hand, if there are nearby signals -- and I am using a 2.1KHz roofing filter when I have APF on -- then narrowing the DSP to 50 or 100Hz with the 250Hz roofing filter seems to work better. 73 Bill AE6JV --------------------------------------------------------------------------- Bill Frantz |"Web security is like medicine - trying to do good for 408-356-8506 |an evolved body of kludges" - Mark Miller www.pwpconsult.com | From drewko1 at verizon.net Fri Feb 5 22:35:12 2016 From: drewko1 at verizon.net (drewko) Date: Fri, 05 Feb 2016 22:35:12 -0500 Subject: [Elecraft] K3/K3S noise blanker performance greatly enhanced (at my QTH) -- need testers In-Reply-To: <1454695065.3174.124.camel@nk7z.net> References: <8C1A61DA-B2A4-46E0-9321-896FE8579C3D@elecraft.com> <1454695065.3174.124.camel@nk7z.net> Message-ID: <56B569F0.4090301@verizon.net> I'm glad that noise solutions are being investigated.

I thought I made that point clear. And it's not just common-mode currents. It all depends upon the load. A "dipole" antenna, for example, is seldom exactly the same distance from surrounding objects on each half, which will "unbalance" the load and so unbalance the currents on the feed line. As Don points out, the currents emanating from the SO-239 connector are balanced when you consider the current flowing on the outside of the center conductor and on the inside of the coax shield (what goes on along the outside of the shield is a totally different situation - RF flows along the surface of a conductor so completely different currents can appear on the inside and outside of the shield, assuming it's a good shield.) 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Ian White Sent: Friday, February 5, 2016 2:24 AM To: 'Wes (N7WS)'; elecraft at mailman.qth.net Subject: Re: [Elecraft] Balun suggestions Wes's point is that twin feeder is not automatically "balanced" - very far from it! Twin feeder happily supports both differential (equal and opposite, balanced) currents and common-mode current at the same time. So, in the real world, there is no such thing as "balanced" feedline unless YOU actually DID something to FORCE it to be balanced. And the way to do that is to insert a common-mode choke that enforces equal-and-opposite currents at that particular location... though even then, it can do nothing to prevent the regrowth of common-mode current elsewhere along the line. 73 from Ian GM3SEK -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Wes (N7WS) Sent: 05 February 2016 00:18 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Balun suggestions I just pinched myself; I'm not dreaming and it's not April 1st, so I guess you're serious.

I lifted the "original" FT-1000D APF from the schematic in 2009 and Al W6LX did a circuit simulation on it. Al's description provided the roadmap for what Elecraft eventually implemented in the K3's DSP in 2010. http://www.mail-archive.com/elecraft%40mailman.qth.net/msg105227.html As Wayne has suggested previously, APF works best if you use a relatively wide DSP setting (I use 400 Hz). I trick my K3 into using my 200 Hz XFIL at DSP=400 by setting the XFIL BW to 400 (similar idea to what Wayne recently suggested with the 2.7/2.8 XFIL for better NB). The wider DSP BW keeps the ringing down and gives your ear/brain a better background to discriminate signals through the 30 Hz APF without ringing while the wide (5 pole) 200 Hz XFIL still gives good protection from nearby strong signal overload. Setting the VFO is not as critical compared to narrow DSP settings, and I use APF virtually all the time...even in contests. This signal path may help visualize what I'm doing: signal >> 200 Hz XFIL >> 400 Hz DSP >> 30 Hz APF >> ear/brain 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/APF-audio-peaking-filter-on-the-K3-K3S-KX3-tp7613416p7613632.html Sent from the Elecraft mailing list archive at Nabble.com.

I love it! I've found it necessary to use both the shift and Fine tuning-- these are not optional for effective use of APF. I've been using macros to engage and dis-engage the APF. One reason I keep combing through the Elecraft Reflector postings is for gems such as Brian's suggestion below. There is always something new to learn. Thanks, Brian. 73, Chuck NI0C KX1, K2-10, K3 Quote: The technique I'm using with the APF also involves NR like so: On an uncrowded band, set the DSP BW to 700 to 1000 Hz. If you have a roofing filter in that range stay within it. Turn on NR set to mF5-3 or there about. The wide BW helps the NR work well. The "mix" mode lets a little unprocessed signal+noise through. This is a good weak signal search mode. When you find a signal you want to copy, turn on APF and peak it in the filter. Fine tuning helps. There is little ringing because NR has reduced the noise amplitude. You can decrease the DSP BW a little but the NR is more effective with uncorrelated noise. This technique has gotten me many pelts in the QRP Fox Hunts. 73, Brian, K0DTJ From k2vco.vic at gmail.com Sat Feb 6 08:08:58 2016 From: k2vco.vic at gmail.com (Vic Rosenthal 4X6GP/K2VCO) Date: Sat, 6 Feb 2016 15:08:58 +0200 Subject: [Elecraft] K3/K3S noise blanker performance greatly enhanced (at my QTH) -- need testers In-Reply-To: <1454754874893-7613631.post@n2.nabble.com> References: <8C1A61DA-B2A4-46E0-9321-896FE8579C3D@elecraft.com> <56B4D48D.4080905@verizon.net> <1454754874893-7613631.post@n2.nabble.com> Message-ID: <56B5F06A.901@gmail.com> I just discovered the same thing.

Something like: Change VFO A to frequency at bottom of band TUNE //the value for that match is stored in memory of tuner Change VFO A to previous frequency plus some delta (for example, increment by 10kHz) TUNE //the value for the match is stored in memory Repeat until at end of band.

First, no birdies found on any of the bands. WHEW! Noise on the 160M center fed wire w/balanced feed line is about S-3 this morning, noise on the coax fed 75M inverted V is S-2, and noise on the coax fed 40M inverted V is S-3, and noise on the coax fed 20M inverted V is S-3. These seem to be a bit higher then normal but it is Saturday and everybody is home in the neighborhood. Our system arrives with fiber underground to the box the TELCO provided on the end of the house. Out of that box runs a CAT5E cable up the wall, into the attic, across the attic and drops through the ceiling, then around the bookcase desk to the modem/switch sitting under the desk. The modem/switch is a CISCO LinkSys EA4500. Two of the ports are being used, printer and laptop, and the other two are open. The power for the modem/switch, power for the computer, the printer, the CLF lamp on the desk along with the radios all come from one power source being a dedicated 20A service back to the main breaker panel, again at the far end of the house, on the inside wall, being the same wall the CAT5E cable runs up to the attic. The run from the TELCO box to the station is about 75 ft. Same from the breaker panel to the operating position for station and amp power. Those feeds are #12-2 w/ ground and #10-3 w/ground respectively. Being in the middle and upstairs of a 2 story house there is no station ground to the outside world, other than the provided safety 3rd pin ground as required. I do have a dedicated 240V 20A service for the amp and that service is in the attic back to the main breaker panel. Antennas are all above the roof, no more than 50 ft and less with the tower at the corner of the house, and mostly less with a couple, 40M wire and 20M wire actually having the ends terminated at the eve of the 2nd story. The point being, there is not a lot of physical separation between the CAT5E cable and the antennas and power wiring. To me it is very puzzling why so many seem to have issues and a few do not. I could elaborate about station equipment connectivity. It would most likely start a controversy as to what is correct and what is incorrect. My point, if one is having issues, this should trigger a thought to investigate how and what is configured with the station. In some cases, I'm sure certain equipment is more prone to generate noise/birdies than others. 73 Bob, K4TAX On 2/6/2016 11:24 AM, Larry Gauthier (K8UT) wrote: > John > > I think I have been mis-understood; or perhaps I mis-spoke. ;-) > > I could not migrate to gigabit ethernet from 10 MBPS because the CAT5 > cable I was using only had two available pairs.

It is coax wrapped around a ferrite core, with appropriate connectors in a plastic weathertight box. I used RG8X coax, a 2.4" core, not sure exactly what mix, and 11 turns. How do I test this device to get its properties, impedance at various frequencies, etc? It appears to function when I put it inline. The KAT100 seems happy. It produces a decent match on 40-10m using the 44' long rotating dipole at ~37' fed with 450 ohm twin lead. I have no idea how efficient it might be, of course, if at all.

I have a new K3S radio that uses the new USB for Sound and Radio Control. For RTTY contesting I use N1MM+ with the MMTTY interface. Since the USB Codec control appears to act differently than a standard serial port, I need to put the Radio in VOX to key RTTY in N1MM+. In the past with my older K3 which used a standard Serial port connection, I did not have to do this. My K3 Settings are: Tx Data Mode (AFSK A), with PTT-KEY in rts-dtr . No difference in Safe versus unsafe modes. It also requires the VOX on in FSK mode too. When I use must MMTTY by itself, I can key with the correct Com port. I am sure this has something to do with how N1MM+ interfaces with the new K3S USB Codec . I have not tried this with other RTTY programs such as FLdigi, etc. Everything works fine in CW, DVR Memory keying with the correct codes, etc. With Ham Radio Deluxe, since it uses a TC/IP connection between the software and radio, I do not need to have TX Data in VOX on mode. I am not sure to eliminate the requirement for VOX on, if it requires an update in either K3S firmware or how N1MM+ interfaces with the K3S USB Codec commands. - Or we just stay with VOX on when contesting. Food for thought and what are others experience with the K3S and N1MM+/MMTTY in RTTY contesting?

Cat5/6 cable in and of itself is pretty immune to noise pickup because of the twist in the conductors. That twist is there to knock down crosstalk on the 4 pairs when in full duplex Ethernet service. The only warning I'm aware of concerning routing of Cat5/6 is to keep it away from power runs. Most definitely do not run it parallel for any distance with unshielded romex, and if you have to cross romex do it perpendicular to the romex run. I've seen new houses built with all the wire running parallel in a piece of conduit in the wall. Looks pretty but a recipe for all sorts of problems like slower than expected or advertised network performance etc....Power up from the basement and Ethernet down from the attic is a good idea.

The significant parameter is the common mode (CM) impedance. G3TXQ discusses a way to measure it here: http://www.karinya.net/g3txq/chokes/#measurement You can back into whether the CM is high enough by terminating each output with a resistive load to ground and measuring the two output voltages and phases with something like an HP8405 Vector Voltmeter.

I've seen cases where even "solid" dielectric did that over time because, after all, it is not really solid. The dielectric is plastic so the coax can be bent. All coax has a minimum bending radius specification. Specific data is available on line but, in general, RG58 size cable usually has a minimum radius of 1 to 1.5 inches (2.5 to 3.8 cm) and RG8 size cable has a minimum radius of at least 2 inches (5 cm). Note that is radius. If you curl the cable into a circle the minimum diameter of that circle should be at least twice that or 3 to 4 inches (7.5 to 10 cm). It's not something I've found especially critical in HF applications at least around my shack, but tighter bends, which may not actually cause a short (yet), alter the impedance as the center conductor migrates toward one side so it is no longer equally spaced within the shield. This can be a serious issue in microwave and even UHF installations. 73, Ron AC7AC -----Original Message----- I would have concern that long term usage of RG-8X, being foam core dielectric material and bent in a tight radius, may allow the center conductor to migrate to the inside radius of the bend. The Minimum Bend Radius for RG-8X is 2.50". Thus the tight bend will allow the center conductor to short to the shield.

There are three separate connections needed for operation in data modes (possibly four in FSK). The first of these connections is for rig control from N1MM+. On a K3, this is the RS232 port. On a K3S, you can use the USB connection instead, provided the K3S's CONFIG:RS232 is set for USB. Either way, this represents one serial port in the software. N1MM+ must be configured to use this port for rig control, and this port cannot be used by MMTTY when it is run from within N1MM+. This last limitation (inability to share a serial port between the two programs) is why the configuration that you use in MMTTY stand-alone does not work when you run MMTTY from N1MM+. The second connection is for audio to and from MMTTY. On a K3, there are actually two cables for audio, one in and one out, but on a K3S, these can be replaced by a single USB connection to the USB codec inside the radio. This happens to be shared with the same USB cable that conveys rig control, but there are two separate and independent devices as far as the software is concerned - one is a serial port, the other is a sound card, and there is no interaction between the two in the application software. This audio connection is used for receive audio, and in AFSK, for transmit audio. MMTTY is configured to use the radio's USB codec as its sound card; N1MM+ does not need to use the sound card at all in data modes (SSB is another story, but I won't go into that here). The third connection is for TX/RX control, or PTT. There are several ways of doing this on the K3/K3S, and it can be controlled either in the radio, or in N1MM+, or in MMTTY - pick one. In AFSK (or in CW), the method internal to the radio is VOX. If you use VOX, you do not need to, and for the sake of avoiding confusion you should not, configure any other method of PTT either in N1MM+ or in MMTTY. However, VOX does not work in FSK D. If the radio is in FSK D, PTT must be controlled some other way (either via radio command or via a hardware PTT connection). A second method is to use software radio commands from N1MM+ over the radio control line to control PTT. This method can be used by MMTTY when it is run stand-alone, but it is not available to MMTTY when it is run from within N1MM+ because of the inability to share the port. If you use this method, you do not need either a hardware connection or VOX. A third method is to use serial port keying, by convention usually done on RTS, although it is possible to use DTR. In most radios, this has to be a separate port from the radio control port, and it has to be through a keying circuit. The K3 and K3S are exceptions - you can use RTS on the radio control port without any keying circuitry by setting CONFIG:PTT-KEY to RTS-OFF (or RTS-DTR to allow CW keying on DTR). This must be done from N1MM+, not from MMTTY, because the radio control port cannot be shared between the two programs. You can also use a different serial port for PTT control, in which case it would be connected through a keying circuit to either the PTT IN jack or to the ACC connector on the K3/K3S. Since this is a different serial port from the radio control port, you can choose to use it either from N1MM+ or from MMTTY. The fourth possible connection (which may be shared with the third PTT method) is for FSK keying from MMTTY, which is applied via the ACC connector. This can be done from a serial port through a keying circuit, but it must be a different serial port from the one used for rig control. This is a hardware limitation, not just software. The FSK serial port must be configured in MMTTY, and there is normally no need to mention it at all in N1MM+. MMTTY can also use this same port for PTT control, in which case you do not need to configure a PTT method in N1MM+. It is possible to configure a serial port used by MMTTY in N1MM+ in such a way that N1MM+ only uses it in CW/SSB and hands it over to MMTTY in data modes, but this is only necessary if you need to time-share the FSK port with other uses in other modes, or if you want to use FSK with the built-in MMVARI engine in N1MM+. There is another way to do FSK, and that is via radio control commands embedded in CAT1ASC macros in N1MM+, but this method is not supported by the N1MM+ programming team, i.e. you are on your own if you try it. There is no TCP/IP connection to the radio. HRD may use TCP/IP for intercommunication between its software modules, but the K3 or K3S has no Ethernet connection and no way to use TCP/IP. Bottom line: You may use VOX in AFSK if you choose to do so, but it is not necessary if you have correctly configured one of the other PTT control methods. 73, Rich VE3KI KD3TB wrote: > I have a new K3S radio that uses the new USB for Sound and Radio Control. > For RTTY contesting I use N1MM+ with the MMTTY interface.

I made a 1/2 wave balun for a 432 yagi. I used Times FM-8 foam coax. (RG-8 sized with low loss foam dielectric) and it was bent in a U shape that did not exceed the bending radius. I tested it with a 700 watt output amplifier and the VSWR went through the roof in under a second. The coax center conductor drifted away from the center at the midway point of the balun and caused the high VSWR. It did not short out, but was rendered unuseable. I ended up making a 1/4 wave balun with copper pipe and a Delta match. Don't use foam coax for high voltage either!

One important point to note is that noise reduction is normally aimed at reducing subjective noise and therefore reducing fatigue. Generally what you are doing is actually recognising signal, then suppressing those frequencies that are not conveying the signal. The noise on the same frequencies as important parts of the signal still gets through. You cannot remove noise unless you have first identified the signal, so you cannot remove the noise that is masking an unknown signal. The simplest noise reduction is a narrow band CW filter! The ultimate noise reduction for CW would be to decode the signal, and regenerate it, but that is currently only possible for signals that are already clean an well formed. Decode and recreate might be the ultimate solution for hearing aids, as well. -- David Woolley Owner K2 06123 On 06/02/16 03:35, drewko wrote: > I'm glad that noise solutions are being investigated.

RG400 uses a fine stranded silvered copper center conductor that is more flexible than its Teflon dielectric. It has a double shield made from silvered copper strands. That's silvered strands whose silver sulphide patina or tarnish is conductive as opposed to the green copper sulphate that separates copper strands that have been water soaked. Wind the coil form with RG59 to get the length and buy just what RG400 you need. You can buy brand new RG400 by the foot. With the Teflon dielectric you can solder the RG400 without worrying about melting it.

I'm thinking it is still here, one of the many things yet to be uncovered in his shack. Its in a blue plastic enclosure, I'll know it when I see it. He'd been a ham since 36 or 37 and he was an EE, worked for General Dynamics in their Sub division. He made an audio filter for CW that managed to not have noise affect the generated signal unless the signal was garbled past intelligibility, in which case no tone was generated. I remember him remarking how much more narrow the audio was and that it was narrower by far than the narrowest CW filter on his Collins. It would regenerate that garbled CW tone into a regenerated tone devoid of any noise in the background. It had to have a decent enough sound to work with but I remember hearing the pure generated note being free of any garbage with it. 73, Gary KA1J > The simplest noise reduction is a narrow band CW filter!

I'm confused by this statement. CAT5, 5e, and 6 are four pair cables. The pairs have a tight twist but each has a different twist ratio ("lay") to minimize crosstalk. If the cables are wired per the Ethernet standard, each circuit should utilize one of the pairs, and in a specified order. What am I missing? Now, we can do lots of things with that cable besides Ethernet -- I use it for RS232 and for running telephone pairs around my home. 73, Jim K9YC From jim at audiosystemsgroup.com Sun Feb 7 00:35:15 2016 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sat, 6 Feb 2016 21:35:15 -0800 Subject: [Elecraft] Balun Questions In-Reply-To: References: Message-ID: <56B6D793.5000104@audiosystemsgroup.com> On Sat,2/6/2016 4:33 PM, Jim Allen wrote: > Almost all of G3TXQ's tests on his website with ferrite core baluns involved RG58, so I figured RG8X would be even better. I have a lot of it, and no RG58. Did you study the material on my website? My measurement method is clearly described in several of the publications, including the RFI tutorial, the AES Paper, and the Power Point for talks I've done for several ham clubs and conventions. The equipment consists of an HP Generator and HP Spectrum Analyzer (which was used as a terminated RF voltmeter). My work, and its publication precedes G3TXQ's by at least five years. His work is clearly inspired by mine (and I would think by W1HIS's), yet he fails to credit either of us. All of my writing credits others who have made important contributions on the topic I'm writing about. I did, for example, reference work and texts by Henry Ott, Clayton Paul, W1HIS, E. C. Snelling, Neil Muncy, Bill Whitlock, Jerry Sevick, and Doug DeMaw in the RFI tutorial. The "Cookbook" that is part of my RFI tutorial is based directly on the measured data that is discussed throughout the tutorial and summarized in Appendix One. 73, Jim K9YC From k2av.guy at gmail.com Sun Feb 7 01:07:48 2016 From: k2av.guy at gmail.com (Guy Olinger K2AV) Date: Sun, 7 Feb 2016 01:07:48 -0500 Subject: [Elecraft] Balun Questions In-Reply-To: <7DC6F8DC-4E7D-4D84-A709-8C5D807EC83C@nobis.net> References: <41082E94-7E41-49AE-935B-2AB630359126@gmail.com> <56B64DBC.1080502@blomand.net> <000301d1612e$719a69f0$54cf3dd0$@biz> <7DC6F8DC-4E7D-4D84-A709-8C5D807EC83C@nobis.net> Message-ID: RG303 is not rated for the tight bends.

I can recall Googling a topic and having a paper come up on some Canadian's website that appeared to be written by him but in fact was my ladderline paper. I emailed him and asked him nicely to remove it and simply link to my site. He refused to do so, so I contacted his ISP and made them aware that he was violating their TOS. I guess he gave them a ration of crap so they closed his account. Bill Orr had my noise blanker circuit in his Handbook for years without me even knowing about it until a friend mentioned it. Of course, Ham Radio Magazine held copyright and I suppose gave him permission but it would have been nice to know. It would have been even nicer to have received a copy. Another example: A good friend of mine who is a stunning photographer https://www.flickr.com/photos/gauchocat/ had someone tell him, "Hey Glenn, I saw your photo in Audubon Magazine." You guessed it, downloaded from Flickr. Jim does excellent work; he should get credit for it.

Pure tone, no noise CW, as from a practice oscillator or an S9++ signal quickly becomes boring and I loose concentration(or something). It's perhaps why I prefer to dig out weak signals (ESP) from the noise on the band.

Several years ago I decided to try to minimize network caused birdies by obtaining some clamp-on ferrites, but also bought some shielded Cat 6 cable to replace generic Cat 5e in the shack. The shielded Cat 6 was very effective in minimizing many 2m birdies. The clamp-on's were largely ineffective. I did this mainly to improve 2m for eme operation. I did not check HF frequencies. Generally atmospheric noise floor is high enough to bury birdies; 10m and 6m seem most effected. We bought a new Netgear router (replaced Linksys) and I had some thoughts to enclose it in a shielded enclosure with ferrites on outputs and cooling fan, but then my wife acquired a ipad and kindle which all run on wifi...so shielding would interfere. I am considering building onto the garage a new 18x26 foot ham shack so that might improve isolation from the router which would be 72 feet at the other end of the house. I still run wired internet cabling to shack computers. I suspect the wifi in neighborhood is bigger issue as is picked up thru the eme antennas and preamps. I am about to disconnect the XP desk top computer from internet and run e-mail and internet only on my laptop. Be interesting to see if that impacts VHF birdies any appreciable amount (K3 and KX3 are connected to the XP computer). I can eliminate the 5-port ethernet switch when I do that and only run a single 25-foot +cable from the router to laptop. Other thing will be elimination of all wall wart PS in new shack (only have the one laptop PS unit). ---------- My laptop just acquired a 21-inch monitor (from my wife's old XP desk top which is being recycled; she bought a new laptop last year with win7 now upgraded to win10...and the desk top was never used after that. Going thru a general "spring cleaning" to reduce household clutter and computer got added. So the shack now has two full-time computers with monitors which will be handy when monitoring prop loggers and running special ham sw, simultaneously. 73, Ed - KL7UW ----------------------- Date: Fri, 5 Feb 2016 07:43:37 -0600 From: Clay Autery To: elecraft at mailman.qth.net Subject: Re: [Elecraft] slightly OT -- acceptable network switch (aka Linksysproduces birdies) Message-ID: <56B4A709.5020102 at montac.com> Content-Type: text/plain; charset=windows-1252 If changing the cabling was the solution for your "birdies" then it would appear the issue was not with the switch hardware, but with poorly constructed cables. There are a LOT of CAT-5 and CAT-5e labels on cables out there that simply aren't. There's a list of specs involved, fairly lengthy one, all of which must be met to qualify a cable at a specific grade. Most cables that fail a check because they missed something in the termination procedure (not signal routing). ______________________ Clay Autery MONTAC Enterprises (318) 518-1389 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From Andy at rickham.net Sun Feb 7 05:18:29 2016 From: Andy at rickham.net (Andy McMullin) Date: Sun, 7 Feb 2016 10:18:29 +0000 Subject: [Elecraft] K3S and RTTY Contesting with N1MM+/MMTTY In-Reply-To: <56B67AEA.7050608@storm.ca> References: <56B67AEA.7050608@storm.ca> Message-ID: <58BF948E-36C1-42E8-8B52-7852F2BEC02C@rickham.net> Excellent answer Richard.

On a K3, this is the RS232 port. On a K3S, you can use the USB connection instead, provided the K3S's CONFIG:RS232 is set for USB. Either way, this represents one serial port in the software. N1MM+ must be configured to use this port for rig control, and this port cannot be used by MMTTY when it is run from within N1MM+. This last limitation (inability to share a serial port between the two programs) is why the configuration that you use in MMTTY stand-alone does not work when you run MMTTY from N1MM+. > > The second connection is for audio to and from MMTTY. On a K3, there are actually two cables for audio, one in and one out, but on a K3S, these can be replaced by a single USB connection to the USB codec inside the radio. This happens to be shared with the same USB cable that conveys rig control, but there are two separate and independent devices as far as the software is concerned - one is a serial port, the other is a sound card, and there is no interaction between the two in the application software. > > This audio connection is used for receive audio, and in AFSK, for transmit audio. MMTTY is configured to use the radio's USB codec as its sound card; N1MM+ does not need to use the sound card at all in data modes (SSB is another story, but I won't go into that here). > > The third connection is for TX/RX control, or PTT. There are several ways of doing this on the K3/K3S, and it can be controlled either in the radio, or in N1MM+, or in MMTTY - pick one. > > In AFSK (or in CW), the method internal to the radio is VOX. If you use VOX, you do not need to, and for the sake of avoiding confusion you should not, configure any other method of PTT either in N1MM+ or in MMTTY. However, VOX does not work in FSK D. If the radio is in FSK D, PTT must be controlled some other way (either via radio command or via a hardware PTT connection). > > A second method is to use software radio commands from N1MM+ over the radio control line to control PTT. This method can be used by MMTTY when it is run stand-alone, but it is not available to MMTTY when it is run from within N1MM+ because of the inability to share the port. If you use this method, you do not need either a hardware connection or VOX. > > A third method is to use serial port keying, by convention usually done on RTS, although it is possible to use DTR. In most radios, this has to be a separate port from the radio control port, and it has to be through a keying circuit. The K3 and K3S are exceptions - you can use RTS on the radio control port without any keying circuitry by setting CONFIG:PTT-KEY to RTS-OFF (or RTS-DTR to allow CW keying on DTR). This must be done from N1MM+, not from MMTTY, because the radio control port cannot be shared between the two programs. > > You can also use a different serial port for PTT control, in which case it would be connected through a keying circuit to either the PTT IN jack or to the ACC connector on the K3/K3S. Since this is a different serial port from the radio control port, you can choose to use it either from N1MM+ or from MMTTY. > > The fourth possible connection (which may be shared with the third PTT method) is for FSK keying from MMTTY, which is applied via the ACC connector. This can be done from a serial port through a keying circuit, but it must be a different serial port from the one used for rig control. This is a hardware limitation, not just software. The FSK serial port must be configured in MMTTY, and there is normally no need to mention it at all in N1MM+. MMTTY can also use this same port for PTT control, in which case you do not need to configure a PTT method in N1MM+. > > It is possible to configure a serial port used by MMTTY in N1MM+ in such a way that N1MM+ only uses it in CW/SSB and hands it over to MMTTY in data modes, but this is only necessary if you need to time-share the FSK port with other uses in other modes, or if you want to use FSK with the built-in MMVARI engine in N1MM+. > > There is another way to do FSK, and that is via radio control commands embedded in CAT1ASC macros in N1MM+, but this method is not supported by the N1MM+ programming team, i.e. you are on your own if you try it. > > There is no TCP/IP connection to the radio.

I am curious to know if you see something different. Using Mode DATA A (Important because it turns off any transmit equalisation and compassion you may have set on SSB mode). Initially turn Power down to 0 while setting up. To prevent any accidental QRM, or use a dummy load. While sending data from the digital software, adjust mic gain and or level from sound card interface to get just over 4 bars on the "ALC" bargraph. This is not really ALC but rather audio level that the bargraph is displaying. It is not until 5 bars that ALC is actually produced, so try to keep it just below 5 bars. The transmit audio level is now set correctly and should need to be touched again. Still while transmitting data you can now adjust POWER with the control and you will not see any change in the ALC level, however the power that you have set will be shown in numerals on the display. If you have an external RF power meter you can confirm that indeed the power level is adjusted in realtime as you vary the POWER control while transmitting in DATA A. [It is this part that you seem to have a different result? Are you saying the POWER control does not adjust the power out while transmitting ? - It most certainly does on my KX3] It is important to not try and adjust power by varying the audio level from the sound card interface or the mic gain control, as that will lead to an unstable power level. Ignore any online instructions that tell you to adjust power and ALC by audio level adjustment, they refer to non Elecraft radios which work in an entirely different manner. 73 from David GM4JJJ > On 5 Feb 2016, at 16:37, Thorpe, Jeffrey wrote: > > I actually noticed the same thing too...the only difference was that I was transmitting Contestia 4/250. > > Jeff - kg7hdz > >> On Feb 5, 2016, at 08:36, Jim Rodenkirch wrote: >> >> Hey, guess what I found out.....I saw the same thing while operating JT9/65. >> >> BUT, every time I rotated the pwr control knob, the ALC was exactly where I >> had adjusted it to, SOOOOOOOOOOOOOOOOO, I experimented a little and varied >> the pwr out prior to transmitting.....guess what????

Isn't it a wonderful day to be alive! :-) Ed, what follows is not directed specifically AT you... or anyone else for that matter. I am just trying to put this whole thread into perspective. I can only speak to the subject from the perspective of my experience, which at the time was to design and construct networks for customers that exceeded the requirements of "normal customers". For these customers, for whom money was less of an object, and things like signal integrity, operating "overhead", and signal security were essential priorities. 1) As best as technology provided, allow no external signal to invade the data network's signals paths to either alter or obstruct that which was intended to travel within it. 2) As best as technology provided, allow no internal signal to escape via the data network's signals path to either be intercepted and/or become an interference source to coincident systems. 3) As best as technology provided, design should provide an operating margin (or overhead) of NLT 50% excess to that contained in the minimum requirements list. The equipment/systems I was to provide was to be housed in a series of (for lack of a better word) vaults with something like a "super Faraday cage" build into the panels. The rooms were connected by a series of separate cable-ways having the same construction (separated by signal and power and by signal type). If you zoom out on the whole structure, it would resemble a series of 100% shielded device chassis, interconnected by shielded, multi-conductor cables, with the 100% shielding terminated at each chassis structure to which it connected. Sound familiar? It should certainly LOOK familiar... Add a good connection to ground, and you have a series RF to ground system to keep RF off the device chassis in the shack... MY task was to construct the data network within the space described above to include the provision of power systems to feed the network. Yet, everything I provided was required to perform with the ASSUMPTION that ALL of what I JUST described above had been totally compromised as to be assumed NON-existent. So, the testing phase of our build-out was done under as close as possible to "real world" operations utilizing a bogus data set IN FREE AIR, meaning in an otherwise unprotected environment (like an office building or your home or out in the center of your front yard really). Point is... We build that network and tested it. Then the customer tested it with equipment I was not even allowed to look at (really well-made device chassis with little to no indication as to function, separate security/shipping boxes that contained what I can only presume were remoted control heads, etc, etc... racks of the stuff. I and my folks were put out of the facility, and they tested items 1-3 (not inclusive) above "IN FREE AIR". We passed... The mystery test equipment and people went away. We went to work. I tell you ALL of the above to tell you this. I hand-made every single Ethernet jumper cable used in the system above (RJ-45 on either end). EVERY SINGLE ONE. I made the terminations for almost every single modular plug. I made every single termination on every patch panel. I used off-the-shelf, quality CAT-5/5e UTP cable stock in stranded/solid varieties rated for where it was to be installed. I used quality RJ-45 (4P8C) modular connectors and connector boots and/or modular plugs. I used quality tools. I terminated each end of every cable using the specification for the standard. I tested every single cable for signal routing and quality of signal. But I did not use SHIELDED TWISTED PAIR cable. There was not ONE SINGLE INSTANCE of my CAT-5/5e standard cables being the SOURCE of a "birdie" or any other RF signal that violated the stringent signal requirements placed upon me. NOT ONE. Were there some RF issues to deal with? A few... But as I remember it, none in HF or low VHF. Using my and other equipment we used logic and proper troubleshooting to drill down to the SOURCE OF THE OFFENDING SIGNAL... every single problem SOURCE was DEVICE related. We either corrected the issue, designed a mitigating solution (rarely), replaced the device causing the issue, etc. Signal cabling REVEALS problems. If properly made, they do not CAUSE them. Bottom Line: 1) Do not pinch pennies on cabling. But do not THROW money at cabling to create a band-aid over the REAL source of a problem 2) Use logic and proper troubleshooting to ID the source of the problem instead of trying to HIDE the symptoms. Once the source of the problem is located, ONLY then do you start searching for a solution to ELIMINATE THE PROBLEM, not cover it up. I and an unrepentant over-engineer. But even I choose the RIGHT places to over-engineer.... and in this case, cabling is not one of the places I'd choose. Maybe I'll change my mind some day. I doubt it. ;-) Maybe I should come out of retirement... Y'all have a wonderful morning. LIFE is GOOD because you read this... which means you are alive! 73, ______________________ Clay Autery On 2/7/2016 4:04 AM, Edward R Cole wrote: > Clay, > > Perhaps.

Pure tone, no noise CW, as from a practice oscillator or an S9++ signal quickly becomes boring and I loose concentration(or something).

However I do really appreciate the tools available in the K3 to do this :) APF works great if you really learn how to use it.

Definitely would not work in high activity contests, but fencer clicks would be buried in all the other mess anyway. ;-) I do have a 2.1 in Main which I'll try the next time I experiment. Unfortunately I don't have that in Sub which precludes diversity, which I use for weak signals that the clicks bother. BTW you can NEVER select a narrower TX filter than 2.7/2.8 because the firmware/software will not allow it (even for CW). I know because I tried to do that years ago in an attempt to further cleanse my CW signal. Now the KSYN3A does a great job of that anyway. When I do another experiment with the 2.1, I'll report the results here. 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-K3S-noise-blanker-performance-greatly-enhanced-at-my-QTH-need-testers-tp7613491p7613681.html Sent from the Elecraft mailing list archive at Nabble.com.

See the link to it on the main Elecraft.com web page. Here's the detailed answer from it. Q: Can I move the KPA3 100-watt PA module from my K3 to a K3S, or do I need the new KPA3A module? A: A KPA3 can be used in a K3S. However, we recommend using the KPA3A PA module, because the K3S RF board was optimized for use with the KPA3A's MOSFET power transistors. In a K3S, a KPA3A will typically provide 1 to 3 dB better transmit IMD performance, on average, than a KPA3. Hope that helps.

This is something I was considering myself and investigated. Wayne said the KPA3 and all other K3 options could be used in a K3S. Wayne pointed out that the basic design and specifications of the KPA3A are no different than the KPA3. The KPA3A does have more pins than the KPA3 connecting it to the K3S RF board. Wayne said they did this to minimize voltage drop. So it appears you can put a KPA3 in a K3S, but you can't put a KPA3A in a K3. As I was considering buying a K3S/10 and moving the KPA3 and other options from my K3 to a K3S/10 I saw a post from Don W3FPR advising another poster against this as the KPA3A has current production RF transistors and other components. Meaning how long will the current components in the KPA3 be available. Taking Don's advice I decided to purchase a K3S/100. It arrived Thursday and I will be moving the sub-receiver, filters and other options from the K3. Another thing to consider, if you are going to sell the K3, as I am, a K3/100 will probably be an easier sell than a K3/10. I did purchase the KAT3A tuner because I feel selling the K3/100 with the KAT3 will also make it an easier sell. One other point, the KXV3B is not an option with the K3S as the KXV3A was with the K3. It is standard equipment and comes with the purchase of a basic K3S/10 or K3S/100. If you have the KXV3 or KXV3A in your K3 you can let that go with the sale of the K3. Also, if you have the sub-receiver in the K3 and are moving it to the K3S, you will have to purchase a K3SYNA board for the sub-receiver. 73, Mark, WB9CIF -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Eric-Jan PA3CEV Sent: Sunday, February 7, 2016 12:08 PM To: elecraft at mailman.qth.net Subject: [Elecraft] KPA3 vs KPA3A Guys, Is it possible to pull the KPA3 and KAT3 from my K3 and use them in a K3S? 73 Eric PA3CEV ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to markmusick at sbcglobal.net From frantz at pwpconsult.com Sun Feb 7 12:47:38 2016 From: frantz at pwpconsult.com (Bill Frantz) Date: Sun, 7 Feb 2016 09:47:38 -0800 Subject: [Elecraft] K3 band data lines In-Reply-To: <871t8o698l.fsf@snoopy.tippete.net> Message-ID: I have built a similar switch controller.

But it can cause problems as well. You should add isolation in the form of either small diodes (cathode towards K3) or small resistors (maybe 100 ohms). The problem is that if the Arduino is left powered on when the K3 is off, the Arduino can actually leak power into the K3 through these connections and can actually power parts of the K3 (as in parts, but not all, of the cpu). This false power can lead to other problems, which is why we suggest the isolation diodes. The second thing is to remember that 60 meters is coded as all zeros. The K3 has pullup resistors on the band lines, which will pull the band lines to whatever Vcc happens to be at that time. When the K3 is off, Vcc is zero, which will be the value of the band lines (i.e. not high-impedance). Thus when the K3 is off, you will see a band selection of 60 meters. KPA500 users see this as the KPA500 switches to 60 meters if it is left powered up after the K3 is switched off.

Actually, I miss small variations we used to see regularly on the CW bands - slight chirp on some sigs, variations in keying by people using bugs and hand keys, etc. Gone are the days one could tune across the bands and recognize individual operators and their rigs after hearing just a few characters. All we have left is a little noise to create a listening "environment". Listening to keyers and keyboards on rigs with pristine keying characteristics is to me a lot like listening to a phone band filled with identical computer-generated "voices".

Pure tone, no noise CW, as from a practice oscillator or an S9++ signal quickly becomes boring and I loose concentration(or something).

No, it is limited to the bandwidth of the preselector filters at best. Since the two meter transverter uses 28 MHz as an IF, that would be roughly 28 - 30 MHz. Front end (at 2 meters) RF splitting is not practical since the transverter does not have an externally accessible RX Ant loop (like RX Out/RX In on the KXV3/A/B). 73, ...

That would give you more bars on the ALC meter when in USB mode as compared to DATA A. Are you certain the DATA submode is set to DATA A? The receive path (signals on the waterfall display) is a function of the KX3 audio gain setting and the soundcard input setting. Be certain the computer soundcard is set to LINE IN and the volume slider is set between mid-way and 2/3 of maximum. That is quite different than the transmit path which is from your soundcard output - again set the slider for your soundcard output to about 2/3 of maximum and try again for 4 to 5 bars on the ALC meter when in DATA A mode. 73, Don W3FPR On 2/7/2016 2:26 PM, Steve Watkins wrote: > I recently connected my KX3 with a Signaling USB interface and using FLDIGI on my Macbook Pro. > > I was NOT receiving any signals on the waterfall display when I was in the DATA mode recommended in the KX3 Owners Manual.

That would explain what happened in 2m digital mode eme the other day. I tried changing drive level to my 8877 by raising the K3 PWR level and the amplifier stopped outputting (anode went from 780ma to 80ma (quiescent load)). Checking drive level on my bird power meter showed it dropped from 55w to 5w?? K3 PWR level had dropped to 0.10mw (running transverter mode). So I reset it to 0.39mw and re-keyed into transmit and I again had 55w drive and 1300w output; never repeated the fault. I wondered what had caused this. This was using the K3 and not a KX3 but perhaps the firmware does strange things if you try readjusting RF PWR while in xmit mode (PTT keyed)? If the display switches to ALC then one could be adjusting AF drive instead of RF power (but how? since Line-in is adjusted by the SPEED/MIC knob and not CMP/PWR. (could I have grabbed the wrong knob?). Hasn't repeated so may be just one of those "things". 73, Ed - KL7UW sorry this is old e-mail; catching up reading the digest today.

Not much RFI from photons. Not everyone has access to fiber. Recently our commercial power was knocked off by a falling tree so only I had power (from my Honda Gen) and I noticed that the "RF world" was a whole lot quieter. One could surmise that this was due to no line noise, but also no neighbors had power for their wi-fi's, plasma TV's, grow lights, garage arc welders, etc. This also told me my home appliances were clean! So that limits what one can do short of hooking up dummy loads for antennas. On HF you might try RF filters but that is not a smart thing to do in front of eme low noise figure preamps (i.e. filter insertion loss translates directly into higher NF and the sensitivity of your eme system is destroyed). Be nice to have fiber...maybe we'll get it about the time you install quantum-linked internet. ;-) 73, Ed - KL7UW --------------------------------------------------- Our system arrives with fiber underground to the box the TELCO provided on the end of the house. ==snip To me it is very puzzling why so many seem to have issues and a few do not. I could elaborate about station equipment connectivity. It would most likely start a controversy as to what is correct and what is incorrect. My point, if one is having issues, this should trigger a thought to investigate how and what is configured with the station. In some cases, I'm sure certain equipment is more prone to generate noise/birdies than others. 73 Bob, K4TAX 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From foxfive.vjc at gmail.com Sun Feb 7 17:29:08 2016 From: foxfive.vjc at gmail.com (F5vjc) Date: Sun, 7 Feb 2016 23:29:08 +0100 Subject: [Elecraft] APF (audio peaking filter) on the K3/K3S/KX3 In-Reply-To: <000301d161e0$e3d746c0$ab85d440$@biz> References: <4FE5BED3-C547-464E-B696-423E23A52EC5@elecraft.com> <1454757578638-7613632.post@n2.nabble.com> <000301d161e0$e3d746c0$ab85d440$@biz> Message-ID: Strangely enough, I miss the wide open no filters receiver of my young SWL days.

I usually use my K3 connected to a Focusrite 2i2 external sound card for digital modes. I use a Mac - OS X 10.11.3. It works very well and I like it (the 2i2) even better than the previous USB sound card I used. Yesterday, I got a wild hair and decided to test the KX3 with the 2i2 using WSJT-X for JT65. I connected the KX3 mic to line out and the speakers to line in on the 2i2. The first thing I noticed was the audio seems really low when trying to listen through the sound card to receive audio. Now, this may just be where I?m trying to monitor the receive audio - from the monitor jack on the front. I also noticed a large spike with a dip and then another smaller spike before leveling out on the waterfall display of WSJT-X. I have *no* audio interface going into the sound card from the KX3 so I?m wondering if this is a ground loop issue. I do not have this issue with my K3 and I have no way to connect a ground to my computer other than to use a self-tapping screw and drill a hole in the case which I am not going to do - forget it. Unless you have an iMac, you won?t understand. I switched between LINE and INSTRUMENT on the inputs of the 2i2 but didn?t get much of a change. I did *not* try turning on the 48V phantom power on the inputs. From all I can research and look at on the case, there is no ?ground-lift? switch on the 2i2. On the transmit side, I never could set the ALC to four bars with the fifth just flickering *and* keep output at 5 W. The power would dip down to about 3 W and then go back up to 5W. In addition, there seemed to be a little ringing when transmitting. Now the KX3 is not my main radio, my K3 is. This is not an issue with the K3, but I?d like to see this work with the KX3. I know it works because others have made the KX3 work on JT65 with WSJT-X. Is there anything else I should try before building an audio isolation circuit? Some setting I?m missing? Something I haven?t done correctly? Thanks for the help. 73, Joel - W4JBB From gm4jjj at yahoo.co.uk Sun Feb 7 18:44:26 2016 From: gm4jjj at yahoo.co.uk (David Anderson) Date: Sun, 7 Feb 2016 23:44:26 +0000 Subject: [Elecraft] Wide Spectrum support on Pan Adapter/SDR w/ K3 or KX3 In-Reply-To: <56B7C8DE.6050809@mediacombb.net> References: <56B7C8DE.6050809@mediacombb.net> Message-ID: <4462D2B6-E632-4C82-8B3F-CA03E40F683D@yahoo.co.uk> Kevin, I am doing something like this. I use a KX3 with an external transverter for 144 MHz. I have a 3dB splitter on the IF out of the transverter (14MHz) and send half the signal to the KX3 and half to an SDRPlay RSP running HDSDR. It can display in to 8MHz bandwidth, though I only need a view of about 500 kHz normally to monitor the weak signal portion of the band. The HDSDR software can be configured to control the KX3 via CAT by point and click and the KX3 can control the tuning of the HDSDR whichever you require. SDRPlay works pretty well for this. I have used the SDRPlay directly on 144 MHz rather than on the IF from the transverter, but it does require a band pass filter ahead of it if you have strong out of band signals, it doesn't have great RF preselection unlike the Funcube Pro+ which has a SAW filter on 2m. 73 from David GM4JJJ > On 7 Feb 2016, at 22:44, Kevin Stover wrote: > > Software Radio Labs QS1R will do 2MHz as a standalone SDR covering 10 KHz to 62.5 MHz. > > >> On 2/7/2016 12:33 PM, Bert Rollen wrote: >> All, >> >> >> I have a young friend who wishes to do the following - >> >> >> (my summary, not his words) >> >> >> - Panadapter (or SDR) with 4Mhz or more display (not just a few >> hundred kHz) >> >> - Capable of 144 MHz - 148 MHz >> >> - Point & click control a rig (K3, KX-3, Flex-6700, rig w/ 144 MHz >> transverter etc.) >> >> >> Essentially, he wants typical pan-adapter display and control, but 4000 kHz >> wide (or more) >> >> >> >> SO, do I recall some folks here who have run a separate SDR to drive >> controls on a K3?

As such, they are high impedance, so I don't think there is any way to drive them from the Arduino (short of changing the program/sketch). I normally leave my switch controller powered on with the K3 powered off, and have not experienced any problems. If there were other things in the shack driving the lines, there might be a over voltage issue for the Arduino, but I think there would also be issues with the K3 driver circuitry.

RG400 has the same diameter as RG-58, i.e. 0.195?. See K9YC?s tutorial here: http://audiosystemsgroup.com/RFI-Ham.pdf All of the RF common mode chokes I have made using small cable (i.e. RG400 through RG6) use radii of 1-3 inches with the RG6 tending toward 3? and greater due to the foam dielectric. --- Chuck, AE4CW From: Mel Farrer [mailto:farrerfolks at yahoo.com] Sent: Sunday, February 07, 2016 17:54 To: Chuck Catledge ; 'Guy Olinger K2AV' ; 'Robert Nobis' Cc: elecraft at mailman.qth.net; 'Ron D'Eau Claire' Subject: Re: [Elecraft] Balun Questions SORRY, but the min static bending radius for RG-303 is 25 mm and RG-400 is 35 mm.

The price I've paid is always less than $1.00 per foot, sometimes much less. I've used it to make dozens of RF chokes (1:1 baluns). The small size of RG400 allows the use of a single medium to large clamp-on #31 ferrite that works effectively from 10-160M, conditioned by the number of turns. The large snap-on ferrite will accommodate 10-12 turns; the medium snap-on will handle 5-6 turns. Jim, K9YC's tutorials are excellent. Consult the Fair-Rite website for additional technical data.

The silvered copper strands stand up to migration of dampness in a way not possible with same size copper strands minus the silvering. I have *measured* the dry RF resistance at 1.83 MHz of a 67 foot length of corroded #14 stranded plain copper at 62 ohms. When new this wire had resistance at RF of less than an ohm. I have never found the silvered copper equivalent in anything remotely approaching that degraded state. RG400 wound on the proper core for the job will last a lifetime. 73, Guy K2AV On Saturday, February 6, 2016, Robert Nobis > wrote: > I have used RG303/U for chokes.

Take away the electricity from a couple of miles around and you'd be surprised how quite things become. As to fiber, I can't say our previous copper installation contributed to noise unless the offending signal was piggybacked as a host and thus induced into the copper service. As I have done a bit of EME, VHF & UHF , I do understand how every 0.1 dB of any loss contributes to a higher NF on receive. I'm surprised to learn that your Honda Generator is clean. Mine sure isn't. Of course it is an inverter style thus it has switching pulses. 73 Bob, K4TAX On 2/7/2016 4:22 PM, Edward R Cole wrote: > Bob, > > Could it be that fiber optics cable is the reason?

The choke hangs just below the feed point of my 160M dipole/80M inverted V. The antennas are at 44' (12M). The choke appears to work well and seems to have knocked the noise levels on 160M down an S unit or two. I was able to hear and work DX during the CQ contest further away than before. The cores are separated by about an inch each and the total diameter of the windings is about 8 inches (200mm). I don't think you need to wrap tightly to the cores.

Three things are necessary in a K3 to get receive down to 100 kHz. 1) the new synthesizers 2) the KBPF3 option 3) an added capacitor on the output of a voltage regulator. If you already have the KBPF3 option, there are some changes to be made to that option board. If you have a subRX with the KBPF3 option in it, the capacitor addition and the changes to the option board must be done too. If you are buying a new KBPF3 option, those changes are already present on new boards (purchased after May 2015). 73, Don W3FPR On 2/8/2016 3:02 AM, Gary Smith wrote: > I've already placed the order for a K3s/10 and will be ordering the > Amp and ATU which I can migrate to the K3s.

NI0C KX1, K2-10, K3 Quote: The technique I'm using with the APF also involves NR like so: On an uncrowded band, set the DSP BW to 700 to 1000 Hz. If you have a roofing filter in that range stay within it. Turn on NR set to mF5-3 or there about. The wide BW helps the NR work well. The "mix" mode lets a little unprocessed signal+noise through. This is a good weak signal search mode. When you find a signal you want to copy, turn on APF and peak it in the filter. Fine tuning helps. There is little ringing because NR has reduced the noise amplitude. You can decrease the DSP BW a little but the NR is more effective with uncorrelated noise. This technique has gotten me many pelts in the QRP Fox Hunts. 73, Brian, K0DTJ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to n4kd at bellsouth.net From hhoyt at mebtel.net Mon Feb 8 11:37:53 2016 From: hhoyt at mebtel.net (Howard Hoyt) Date: Mon, 8 Feb 2016 11:37:53 -0500 Subject: [Elecraft] KX3 beta firmware rev. 2.38: 15 Watts max output on 80-20 m, and PSK63 mode Message-ID: <56B8C461.2010202@mebtel.net> Hi Don, Running the new software revision on our development units here (s/n 1403 & 7420), we see 15W output on 80-20M, with the KX3 pulling 2.2-2.5A depending on SWR.

If you have hum or low or distorted audio or something that should tell you. Have you the standard heatsink? If you have sufficient transmit AF going into the KX3 the power should be stable. Start with a low level of audio, because if it is too high it will shut down and this can cause confusion as you think it may be too low. In WSJT-X you get a strange looking spectrum if you have the flatten spectra selected. This is because of the sharp sided filter in the KX3. Untick that option. I presume you have widened the filter out in the KX3 for DATA A. What do you mean by ringing on the transmission? Looking forward to hearing how you are doing. Good luck. 73 from David GM4JJJ > On 7 Feb 2016, at 23:07, Joel Black wrote: > > Need a little help here - or at least someone to tell me if this is normal for the conditions or not. > > I usually use my K3 connected to a Focusrite 2i2 external sound card for digital modes.

For data modes you said you are using the USB codec in the KIO3B, which is not connected to the PC speaker. Try using a speaker connected to the K3's SPKR output (or the internal speaker) to monitor the audio instead. You can adjust the volume of received sounds using the AF control; it shouldn't have any effect on the audio level in the codec (that should be controlled by CONFIG:LIN OUT). You can also adjust the level of monitored transmitted sounds using the K3's MON control, again without impact on the actual transmit audio level (4-5 bars on the AGC meter, adjusted using the LINE IN gain control). 73, Rich VE3KI W4RKS wrote: > Using a K3 > KIO3 B (The new board) > "Y" cable connected to P3 via the RS232/P3 connection > USB cable from the K3 USB to a Windows 7 (32) PC USB port > The P3/Config RS232 is set to "USB" > > Using Ham Radio Deluxe (HRD) Version 6.3.0.450 > The PC shows "USB Audio Codec" for Transmit and Receive. > > CAT control works.

I got a 7805 and powered it from a separate power supply. The negative of the 7805 is connected to the GND of the arduino. If I connect the 5V from the 7805 to one of the digital inputs, the arduino powers up and executes my program, lighting up the leds as expected. If I add the diodes as suggested by Jack, this doesn't happen anymore. But I can't read the 5V from those lines anymore, either. I'm now trying to figure out how to replicate the BAND line driver circuit that is mentioned on Cady's book on my breadboard. Not sure if I can simulate the mosfet by just shorting that line to ground between the 2.2k and the 220 ohm resistors. In any case, in this configuration I have to use the arduino internal pullups, and if I disconnect the external 5V power, I still measure around 1.3 V in the place where there would be the K3's 5V, if I have the arduino still powered up. Also, the logic signal of the lines seems to be reversed. I'm seriously thinking that the safest way for me to proceed at this point would be an optoisolator.

Just a low-voltage-drop diode (1N5711 should work) with cathode towards the K3, pullup resistor (47K to 100K) to +5V (or whatever the Arduino runs on, might be 3.3V), then the Arduino input pin. This will protect the Arduino from being falsely powered from the K3. This is standard design for devices that are separately powered (think hot swap systems) in order to keep the unpowered one from being falsely powered by the one that is turned on. In other words it will keep the K3 from falsely powering the Arduino through the IO pin. The real problem with this is that if the device is powered in this fashion it can actually latch up part (or all) of the chip, damaging it. Adding a diode and pullup resistor (or even using the internal pullup in the Arduino if it has one) is very cheap protection for this scenario. This is something that surprises everyone the first time they see it. It is easily handled once you know what is going on. The pullup resistors were added sometime after the K3 shipped in order to help external devices that don?t have their own pullup resistors. It is not surprising that they do not appear on early schematics, but they are on current schematics. The circuit shows a 2.2K ohm pullup to +5V followed by a 220 ohm series resistor. This will deliver about 2.2mA of current to the IO pin, enough to power some micro controllers. Thus the need for the protection circuit. - Jack, W6FB > On Feb 8, 2016, at 12:48 PM, Pierfrancesco Caci wrote: > > > I've done an experiment. > I got a 7805 and powered it from a separate power supply. > The negative of the 7805 is connected to the GND of the arduino. > If I connect the 5V from the 7805 to one of the digital inputs, the > arduino powers up and executes my program, lighting up the leds as > expected.

The balun you made with a ferrite torroid and a length of coax is a straight piece of coax with the two ends supposedly isolated for CMC common mode current., right?? How do you make a simple measurement on the lowest frequency?? Expensive equipment, right?? Well, what is the next best way to determine the isolation at RF, Hummm.? If I measure the inductance across the two ends of the balun that is shield to shied to make it easy,? the ferrite increases the inductance of the many turns through the core, right??? If you take the number in uH and put it into the: ( Xl= 6.28*F(HZ)*inductance(H)), formula you get an equivalent reactance in ohms at the frequency of interest.? Yes, I know there are other factors, but it gives you a figure of merit against any other current choke baluns, or other designs you would like to try. Remember More is better. ?? Funnnnnn.

So, if you are applying 5V to an input without powering the circuit, in other words, Vcc=0, then you are forward biasing the protection diode. This is very likely what is powering the Arduino via an input port. That's bad because the internal clamp diodes are not designed to conduct much current and you risk damaging the part. Once you understand and look at the actual input circuit and driving output circuit, you'll know if this is something that needs to be fixed. For example, pushing a small current through the diodes when Arduino is unpowered may be fine. Or a series resistor on the input to limit the current. The problem you see with your test may not be relevant since the K3 output line can't source current like a 5V supply. I saw Jack is suggesting a diode, with cathode toward the K3 output port. This is allowing the K3 to pull-down the Arduino input, but not pull it up. That may explain why you can't read the port with the diodes in place. Assuming inputs are directly connected to the Arduino's ATMega processor, you need to make sure the internal pull-ups are enabled in the processor. You can directly measure the port voltage with a DVM to see if they are being pulled up as needed. Sorry for some ignorant conjecture about circuits I haven't looked at, hopefully it's of some use! 73, Josh W6XU On 2/8/2016 12:48 PM, Pierfrancesco Caci wrote: > I've done an experiment. > I got a 7805 and powered it from a separate power supply. > The negative of the 7805 is connected to the GND of the arduino. > If I connect the 5V from the 7805 to one of the digital inputs, the > arduino powers up and executes my program, lighting up the leds as > expected.

The voltage readings below are the average observed on two different KX3s on 40M powered by a Pro Audio Engineering Kx33: Voltage at the DC jack measured on an HP34401A: Rcv: 14.45 VDC Xmit: 14.15 VDC Voltage from the KX3 display PS value: Rcv: 14.1 VDC Xmit: 13.5 VDC The lower readings on the KX3's display are due to the polarity protection diode and other I*R voltage drops /internal/ to the KX3. Elecraft's spec for the 15W power level specifies a supply which can deliver /at the DC power jack/ at least 13.8V at the 2.3-2.5A level needed for 15W output. The PAE-Kx33 design will deliver at the DC power plug 3A at >14.0V, and 4A at >13.9V. If your Kx33 supply is not delivering better than 13.8V at the plug running 15W then please contact us!

Hi Robert, I have wrapped RG400 on a two stack of FT240 form factor toroids with never an issue, without any change in electrical characteristics I could measure. These were a little less than a half inch radius, something I would never try with 303 or 142. A one inch radius or two inch diameter winding, per the listings you have quoted, would hang loose on most forms. In effect this specifies the 303/142/400 cables useless for winding on toroid cores of any HF suitable size in use by hams, including even the monumental T500A series toroids. ***However,*** I respectfully suggest that the minimum bending radius that you see published for RG400 can be ignored for ham purposes at HF and low VHF, and common sense is better suited to the problem. IMHO the ANSI standard (ANSI/SCTE 39 2007) uses a crude method better suited to measuring metallic sheathed cables, and ignores testing the needed characteristics directly, simply to avoid testing cost and complexity. I also suggest that everyone carefully study the ANSI standard until it is clear what they are doing mechanically and see what they are actually measuring: http://www.scte.org/documents/pdf/standards/ANSI_SCTE%2039%202007.pdf The method of measuring is in section 4. They are looking for a limit of 1% surface deformity when bending. In the case of RG400 with .195 inch OD, that would be 2/1000 of an inch (yes, that's three zeros, two one thousandths of an inch) bending deformity at the surface of the teflon jacket, or half the thickness of an average human hair. Anyone who works with teflon knows that the teflon jacket on the outside of the bend will stretch and the teflon on the inside of the bend will bunch, due to the difference in the radius, and particularly due to it being a soft material with no constraint to its outside surface. And there is the problem of managing to measure the thickness of something soft like teflon so as not to compress the teflon 2 mils during the measurement of something with a curved surface. The teflon dielectric between the inside of the shield and the center conductor, all we care about, is confined by the double shield, which opposes the teflon's tendency to deform. Further, the difference in the radius is smaller inside the shield, dividing down the differential measured at the surface of the jacket. The 19 strand center conductor in RG400 will easily follow the teflon in multiple bendings. The solid center conductor versions (303,142) to a degree will remember their first bend and will apply that deformity in the second and later bends, accumulating deformity at that point in the cable unless the second bend is identical to the first. That is why you see "once" or "bend once" in some of the listings for RG303 and RG142. I have no argument with the "bend once" specification in the 303 and 142 listings. It's relates to the reason I use RG400. RG400 is the only coax listed for certified aircraft installations in a lot of aircraft service vendor's web pages. I find 142 mentioned a few times as being easier to fit with connectors. I have not seen 303 mentioned on an aircraft service vendor web page. 73, Guy K2AV From joe at selectconnect.net Mon Feb 8 20:32:59 2016 From: joe at selectconnect.net (Joe Moffatt) Date: Tue, 9 Feb 2016 01:32:59 +0000 Subject: [Elecraft] 160 meters RX antenna for K3 advice Message-ID: I am needing advice from any with a K3 for 160 receive antennas.

It is interesting that the ANSI test is based on physical ?outer surface" deformity, rather than electrical (rf) performance. Although there is probably a degree of correlation between physical deformity and electrical (rf) performance. I agree the ANSI spec outlines a rather crude test. The data I provided came from several manufacturers of coax. I just wanted to point out that the manufacturer?s specifications for both RG303 and RG400 are the same at a 1.0 inch static bending radius. They did not indicate how they came up with these specifications. I believe there is plenty of margin in these specified values that may be required for use in military applications, since both cables are MIL spec rated. However, for ham radio purposes, I believe these specs can be safely ignored, within reason. Although, I probably would not try to bend either RG303 or RG400 any tighter than maybe 0.40 to 0.45 inches. I have used RG303/U because that is what I had. If I had RG400/U, I would have used that. In my case, I have seen no measurable performance issues with the tightly wound chokes that I have made with RG303/U. If care is taken in winding the chokes, I feel either type of coax will do the job. Maybe if I find some RG400/U at the next hamfest I attend, I will buy some and try it. I could then compare results. It would be interesting to do some actual tests of the electrical impact of bending coax at radii needed for 2.4 inch OD cores, either single or stacked. Possibly some type of TDR test could be done to see if any deformaty would impact performance of the coax used in chokes, over the HF ham bands. Again, thanks for sharing your insight and experience. 73, Bob Nobis - N7RJN n7rjn at nobis.net > On Feb 8, 2016, at 18:01, Guy Olinger K2AV wrote: > > Robert Nobis wrote: > > After reviewing specs from several manufacturers, the ?recommended? minimum bend radius for RG303 and RG400 is essentially the same at 1.0 inches. > > Hi Robert, > > I have wrapped RG400 on a two stack of FT240 form factor toroids with never an issue, without any change in electrical characteristics I could measure.

IMHO the ANSI standard (ANSI/SCTE 39 2007) uses a crude method better suited to measuring metallic sheathed cables, and ignores testing the needed characteristics directly, simply to avoid testing cost and complexity. > > I also suggest that everyone carefully study the ANSI standard until it is clear what they are doing mechanically and see what they are actually measuring: > > http://www.scte.org/documents/pdf/standards/ANSI_SCTE%2039%202007.pdf > > The method of measuring is in section 4.

And there is the problem of managing to measure the thickness of something soft like teflon so as not to compress the teflon 2 mils during the measurement of something with a curved surface. > > The teflon dielectric between the inside of the shield and the center conductor, all we care about, is confined by the double shield, which opposes the teflon's tendency to deform. Further, the difference in the radius is smaller inside the shield, dividing down the differential measured at the surface of the jacket. > > The 19 strand center conductor in RG400 will easily follow the teflon in multiple bendings. The solid center conductor versions (303,142) to a degree will remember their first bend and will apply that deformity in the second and later bends, accumulating deformity at that point in the cable unless the second bend is identical to the first. That is why you see "once" or "bend once" in some of the listings for RG303 and RG142. I have no argument with the "bend once" specification in the 303 and 142 listings. It's relates to the reason I use RG400. > > RG400 is the only coax listed for certified aircraft installations in a lot of aircraft service vendor's web pages.

I had my transmit audio too high. Thanks to you and my KE7X KX3 book, I reset my audio in and out of the radio and got consistent transmit output. I think the ringing I was hearing was from me overdriving my transmit audio and hearing it and the monitor on the sound card. I was actually receiving on the sound card what I was transmitting. In KE7X?s book, he recommends setting the audio to LINE IN (@ 50%) to KX3 phones (AF ~ 20 - 30) and LINE OUT (@ 10%) to KX3 mic (Mic Gain = initially 0). I finally wound up with a Mic Gain of about 20 - 21 and could see solid output with the ALC and Wattmeter on the KX3. I *do* have the standard heatsink and, as far as I know, the temperature compensation has *not* been done on this radio. At least I didn?t do it and I don?t think the previous owner did it either. I?ve looked at the heatsinks and will probably buy the Cooler KX Plus from VE7FMN. I just haven?t sat down and ordered it. Is there any one particular you recommend? Thank you for the advice on *unchecking* flatten in WSJT-X. I do have the filter widened out to at *least* 3.0 kHz and sometimes run it on out to 4.0 kHz. Again, I think the ringing on transmit was from me overdriving and hearing both the transmit audio and monitor audio at the same time on the sound card. With the transmit audio now set correctly, I no longer hear the ringing I was hearing previously. Thanks again for the help and advice. 73, Joel - W4JBB > On Feb 8, 2016, at 11:58 AM, David Anderson wrote: > > Joel, > > A few questions for you: > > Can you tell what the transmit audio sounds like by listening using monitor on the KX3?

Yes I use one of VE7FMN's excellent heat sinks, it was an earlier one than the Plus model, and It fitted perfectly and looks and acts the part. I do advise doing the temperature compensation, you will need it for modes like JT65B. If you don't have the XG50 you can use a harmonic of a 10 MHz TCXO or GPS locked source. The exact frequency does not matter, just the stability during the temperature calibration procedure. Once done you won't have to worry about drift. There is a way to tell if the temperature compensation has been done. The menu item REF?CAL will be shown as REF*CAL if it has been done. 73 from David GM4JJJ > On 9 Feb 2016, at 11:35, Joel Black wrote: > > David, > > Once again, thanks for the help. > > I had my transmit audio too high.

You should then be able to get K3Utility to communicate with the K3 over USB. Once you accomplish that, you should be able to download the new firmware through the USB port. If that does not work, set the switch on the back of the board to the RS-232 position and connect the PC (with a USB to serial adapter) to the dongle provided with the upgrade kit - be sure to set the RS-232 menu parameter back to 38400 to use RS-232.

Message-ID: Jim, Thanks for the heads up. I'll try and listen. I wonder if there is any particular band or time of operation. Otherwise, I guess I'll just have to watch the DX cluster. I didn't realize that operating from a ship, in territorial waters, didn't count for DXCC. However, I'm not surprised that I didn't know this tidbit since I'm not an avid DX chaser. I suppose that is because actual location might be a bit "fuzzy" when operating that way, but it sure seems if a ship is docked it ought to count! Hi. So, if I would be operating from a house boat in San Francisco Bay, or maybe San Diego harbor, I guess that wouldn't count as being in California either! Hi. Anyway, it will be interesting to see if I can hear them with that antenna system. A bunch of us on the PQRP reflector have been tinkering with just such an antenna system. 73, Dave W7AQK From w3fpr at embarqmail.com Tue Feb 9 09:39:05 2016 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Tue, 9 Feb 2016 09:39:05 -0500 Subject: [Elecraft] KIO3B Upgrade Kit for the K3 In-Reply-To: References: <0FA2F6D3-6CCF-4E24-A9F6-082577BCBA94@gmail.com> <56B9DB9B.5030206@embarqmail.com> Message-ID: <56B9FA09.4090800@embarqmail.com> I did not check the firmware release notes.

Be certain the switch is returned to its normal position afterwards. Also be certain the RJ-45 plug is fully inserted. You will hear a definite click when it is fully seated.

Finally, I got motivated to finally get my KAT500 connected to my computer! I installed the latest version of the utility and all was good. I was able to view the SWR and FWD/REF power as the unit trained itself (after clearing the memories, first). Then, without warning, the utility stopped recognizing the KAT500. The COM port is still there and it hasn't changed, but the KAT500 is no longer found. Many options are now grayed out. I've tried changing the COM port assignment for the KXUSB adapter, but that does nothing. I tried removing then reinstalling the adapter, which also results in no change. Any ideas what is going on? Could RF have somehow gotten into the controller in the KAT500 to make it not respond to the KXUSB polling? The KAT500 still tunes as usual, but I'm just not able to access the unit at all via the computer interface.

If you exceed the bending radius of your coax, you stand a higher percentage chance of causing a shield to center connector short, (due to center conductor migration), than if you don't exceed the bend radius. ?When running high power, you also stand a better chance of heating up your core material, (and hence your coax), which makes it easier for the center conductor to migrate, and if you have exceeded the bend radius-- well-- ?we're pretty sure where it will migrate too... One has to pick one's fights so to speak, and I would not pick bending radius as one of my fights... ? If you lose, it is never good when the center conductor shorts to the shield at Kilowatt power levels. ?Use loops large enough to stay within the bending radius of your coax. ?Now if this is QRP, you could probably get away with it. -- 73's, and thanks, Dave For software/hardware reviews see: http://www.nk7z.net For MixW support see: https://groups.yahoo.com/neo/groups/mixw/info For SSTV help see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Tue, 2016-02-09 at 09:01 -0600, Bob McGraw K4TAX wrote: > I'm one of the other Bob's or Robert's........ > > Since the assembly of coax wound around a toroid doughnut style > bobbin? > is typically not exposed to vibration, such as might exist in an? > airplane, boat or space vehicle, the use of a solid conductor coax > such? > as RG-303 would not seem to be of concern.??The more important point > and? > my experience and as related by others, the use of coax which has > foam? > dielectric in a tight radius bend has been proven or shown to be? > problematic.????As to if the manufactures bending radius dimension > is? > being violated, I find to be of little concern. > > After all, as a rule, hams are noted for pushing things to the limit > and? > then some and getting buy with it.??If hams choose to "stick to the? > rules 100% in all aspects of their stations"............I'd say 75% > of? > the stuff we use and methods employed would put most of the station? > stuff in the trash. > > 73 > Bob, K4TAX > > > > > > On 2/9/2016 8:45 AM, Guy Olinger K2AV wrote: > > Hi Bob, et al, > > > > Thank you all for your careful attention. > > > > I read it wrong, as several have pointed out overnight.

It's still too early to tell how well Icom will pull it off. I really don't see it as being K3s competition, a more apt comparison being TS-590 and FT-1200. Icom has been quite clear that this will be an entry level radio only. I suspect that compared to the K3s, the IC-7300 will fall short in terms of dynamic range, QSK, etc. 73, Barry N1EU On Tue, Feb 9, 2016 at 10:16 AM, Bill wrote: > Icom is about to release their IC-7300 with rx from .03 to 74.8 mHz, with > a live display, auto tuner, 100 Watts, 15 included bandpass filters, and a > direct sampling receiver.

There are coax cables out there that can run safely too hot to handle. Teflon dielectric and FEP outer cover. It's used in multi kW industrial amps and power combiners, wrapped around many ferrite cores, often with fan cooling, for the ferrite, not the cable! Commercial (Broadcast) baluns too are sometimes immersed in oil, much like power transformers, for cooling. That's at the 10's of kW power level. But the coax is the high temperature stuff again. Use suitable cable for the job, not cheap polyethylene stuff. Dave G0WBX.

There's also text that goes with it, noting that winding radius should follow mfr recommendations for bending radius, that close spacing should be used to lower the resonant frequency and wider spacing to raise it. Note also that the dielectric constant of outer jacket material can have a quite significant effect on the bandwidth of ferrite chokes. For example, the bandwidth of those THHN chokes is MUCH greater than chokes would with typical RG8, RG213, RG11. Years ago, someone sent me a length of one of the teflon coaxes and I measured some chokes. As I recall, their bandwidth was lower than those wound with conventional coax. 73, Jim K9YC 73, Jim K9YC On Tue,2/9/2016 7:45 AM, James Robbins wrote: > > Good morning Jim, > > I am wondering if you could opine about how ?tightly? coax needs to be > wound around a torroid for balun use (or other uses, for that matter)? > > In other words, while there have been so many Elecraft postings about > the bending radii of various types of coax, there is no information > posted about how tightly (closely) the coax needs to be wound around > the edge of the toroid.

I wonder if there is any particular band or time of operation. Otherwise, I guess I'll just have to watch the DX cluster. I didn't realize that operating from a ship, in territorial waters, didn't count for DXCC. However, I'm not surprised that I didn't know this tidbit since I'm not an avid DX chaser. I suppose that is because actual location might be a bit "fuzzy" when operating that way, but it sure seems if a ship is docked it ought to count! Hi. So, if I would be operating from a house boat in San Francisco Bay, or maybe San Diego harbor, I guess that wouldn't count as being in California either! Hi. Anyway, it will be interesting to see if I can hear them with that antenna system. A bunch of us on the PQRP reflector have been tinkering with just such an antenna system. 73, Dave W7AQK From matt.vk2rq at gmail.com Tue Feb 9 13:38:21 2016 From: matt.vk2rq at gmail.com (Matt Maguire) Date: Tue, 9 Feb 2016 18:38:21 +0000 (UTC) Subject: [Elecraft] Competition from ICOM?

The build was complete except for the P/A and Sub Receiver at about 9:45 last night. I completed the 5 watt power calibration, REF CAL and receiver RF Gain calibrations and shut down for the night. Installed the P/A module this morning and ran the 50 watt TX Gain cal. All passed with no issues. I still have the Sub Receiver to go, but my roofing filter set won't be complete until the pair of 6.0 KHz filters arrives tomorrow from Elecraft so I'm holding off on the Sub so I won't have to remove it to install the 6.0 KHz filter on the main board. This was an easy (though intricate) build and even with my somewhat impaired vision, I had no problems with it other than a minor glitch in configuring the filters to leave the FL1 slot open temporarily. My suggestion to anyone else needing to leave FL1 open (for later install of a wider filter and not have to move everything around), use the K3/K3S utility's Filter Configuration app to do this. If you try from the front panel first and not through the computer utility, it may or may not work right. After a couple of tries with the MENU and then back to the Utility, everything finally set up properly. Now when the filters get here, I'll be able to install the Sub RX and change out the older K3 for the K3S.

This is all normal for most shipboard installations. A random length of wire can be matched to effectively transfer RF from the transmitter. Precise length measurements are not necessary. Keep ground loss and other component loss to a minimum and one has a rather decent antenna. Thus one uses an insulated back stay on the vessel. 73 Bob, K4TAX On 2/9/2016 1:06 PM, Barry N1EU wrote: > I think the only important measurement is that it avoids being near a half > wavelength on any bands.

I am on page 4 of the procedure and am pretty sure I have followed the instructions verbatim. I cannot get the CWT indicator to show. Yep, I have auto spot turned on as indicated by the CWT on the display. The pointer never comes up. I never hear a change in pitch either so I?m not sure if any adjustments are being made. Yes, it did occur to me that no adjustments may be necessary but without the CWT marker, I cannot be sure. I am going to go through the procedure again and triple check that I didn?t miss anything. If anyone knows or remembers if the CWT indicator should not be there, that?s fine. It?s just that what I?m seeing and what?s in the procedure are not matching up.

It measures to 250 ft, +/- 1/16". The only challenge is to estimate the wire sag in measuring a long length of wire. The laser is always measuring straight line. For shorter lengths, I stretch the wire tight on the floor of the shop or laying over reasonably level ground and shoot the laser along side. In general hams will construct the antenna and then trim the length {add or subtract length} to get the SWR value to 1:1 or such. 73 Bob, K4TAX On 2/9/2016 1:38 PM, Lynn W.

Case and point, construct a 1/2 wave antenna using insulated wire, put it up and determine the resonant frequency or point where the SWR is 1:1. Then take it down, carefully strip off the insulation and put it back in the same place. Make the same measurements to determine resonant frequency or point where the SWR is 1:1. You'll find it changed due to the K factor contributed by the insulation. 73 Bob, K4TAX On 2/9/2016 1:46 PM, Dave Cole wrote: > Hi Jim, > > I have been reading about your exploits with THHN, and the 100 to 50 > ohm change caused by the insulation... > > I am going to pick some up today and wind a choke using it, (as opposed > to enameled 14 GA copper), to see just how close to 50 ohms it will > come...

Zero sag = infinite tension. Unfortunately, center-fed dipoles are not uniformly loaded. Just lay the wire out on the ground in a straight-ish line and measure it. I use a 50' steel tape. Lots of things will affect its ultimate electrical length when installed, you'll need to prune it some anyway. I just fold the ends back on the wire until I've got the right length and then cut it and belay it to the insulator(s). 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 2/9/2016 12:22 PM, Bob McGraw K4TAX wrote: > The only challenge is to estimate > the wire sag in measuring a long length of wire.

If you have a 100 foot tape measure, just pull out 53 feet and match the wire to that length - that is the way I do it. If you only have a 50 foot tape, measure 25feet, 6 inches and double it back on itself. If you have only a 25 foot tape, measure 18 inches from the end, put the end of the 25 foot tape at that point and measure out the remaining 25 feet, then double it back on itself. 73, Don W3FPR On 2/9/2016 4:12 PM, Lynn W.

I have to come clean and admit that despite more hours with a soldering iron than I would care to count, I made a major error when I completed my recent K3S build. You know that REF CAL procedure where you zero beat WWV? Well... let's just say that I somehow managed to set the oscillator to a value way out of the expected range. I swear I heard that slow beat note about 2Hz away from where the value should have been, but now I don't know how. I re-did the REF CAL procedure using 15MHz WWV today, and now things are hunky dory. The gents at Elecraft provided too much kind support to help figure out my problem and I hope they can forgive me for the time of theirs I wasted. :-) Now, as for the KXUSB not communicating with my KAT500 -- that one is still a mystery, but it appears to be an issue with a KXUSB instead of the KAT500 (whew!). I crafted a serial to stereo cable to connect the KAT500 to my computer, and things worked just fine the first time. I hate to use that serial port for this, but I may have to as the KXUSB is out of warranty (purchased November 2014) despite its first use being last night. Ah well. Thanks for listening, and I hope that this can be a lesson to each of you. Take time on your builds. Don't stay up too late, or do things when you're tired -- or you might completely mess up the REF CAL procedure and cause your narrow filters to "fail". 73 -john NE4U From Gary at ka1j.com Tue Feb 9 17:16:09 2016 From: Gary at ka1j.com (Gary Smith) Date: Tue, 09 Feb 2016 17:16:09 -0500 Subject: [Elecraft] K3s & Rx antenna Message-ID: <56BA6529.21297.107BF524@Gary.ka1j.com> My order is in Queue for a K3s.

Multiply the number of steps times the length of your foot (or feet if necessary). This is very similar to how to count the number of cows in a field.

If you also want the RX antenna to feed the main RX when the RX antenna is selected, you will have to connect it as you have it for the K3.

A short wire (< 1/4 wavelength) depends upon a very, very good "RF ground" or counterpoise system of operate with any efficiency. Above about 5/8 wavelength there is no length that radiates better than any other in general. Only the pattern changes. As you noted, the so-called "magic" lengths that I've seen published are simply those that avoid a voltage loop (high impedance node) at the tuner since most ATUs are not designed to deal with very high impedance loads and if the rig doesn't have a good "RF ground" one easily experiences "RF in the Shack" issues. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Barry N1EU Sent: Tuesday, February 9, 2016 11:06 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Slightly OT: non-resonant wires I think the only important measurement is that it avoids being near a half wavelength on any bands.

You can build your own magic-T splitter from plans at Clifton Laboratories: I've used old "broadband" MATV/cable splitters (typically specified 10 - 1000 MHZ) from the "old days" with no issues all the way down to 160 although the isolation may not make full specs that low.

How long is long enough will vary from temperature to temperature. I suggest that power off for 30 minutes or more will give good results. You need to measure the temperature directly below the PA transistors - which is difficult to do. The best solution is to let everything to acclimate to ambient and set CAL TMP at whatever the ambient temperature may be (in degC). How much do you trust your infrared thermometer is the real question. 2 degrees may not make a big difference. Light on the heatsink can create an apparent difference in temperature. The heatsink can absorb light and make it warmer than the ambient temperature. IMHO, 2 degrees C will not make that much difference in when the fan comes on to either low or high speed. In other words, go with whatever is comfortable with you. The CAL TPA parameter only defines when the fan will be activated. Some KPA100 owners who want to see the fan come on sooner than normal will set the CAL TPA menu parameter to a greater temperature than ambient. In other words, setting CAL TPA to 30 degC when the ambient is 23 degC will turn on the fan earlier than the normal heatsink temperature. Bottom line -- it is an individual decision (but don't go to extremes). 73, Don W3FPR On 2/9/2016 8:22 PM, Brian - N5BCN via Elecraft wrote: > I may be wandering into nit-picky land, but I noticed using a hand held > infrared thermometer that the heat sink of the KPA100 is usually about 2 > degrees warmer than ambient air temperature (when the unit has been sitting > idle for several hours).

Therefore, the 250hz roofing filter will engage at the same time as the 250hz DSP filter. However, since the 250hz roofing filter has an actual BW6 of 370hz, aren't there times when it would be more beneficial to have the "configuration bandwidth" of the 250hz roofing filter set to 350 or 400? I'm thinking this may be especially true when operating RTTY since the average RTTY bandwidth is aprx. 370hz. Perhaps there are times when this would be beneficial when operating other modes as well? Likewise, the 400hz roofer has a BW6 of 450hz, so perhaps for certain modes a "configuration bandwidth" setting of 450 rather than 400 could be beneficial as well? If anyone is wondering where I'm getting the term "configuration bandwidth" from, it's a configuration heading on the K3 Utility programs filter configuration page.

If you need a certain bandwidth for a certain mode, use the narrowest roofer you have in there; just like in any other conventional transceiver. So if you want 350Hz as bandwidth, use that 250 filter (which is actually 370). That's common sense. Don't let the 250Hz tag on the filter fool you. They say they sell you 250Hz, that's just not true. It should have stated 350Hz or so. And in ham spirit: just try out different settings and decide what works best. 73 Arie PA3A Op 10-2-2016 om 6:05 schreef Dick via Elecraft: > snip> > > The factory default roofing filter "configuration bandwidth" setting is to > set the 250hz filter at a setting of "250".

And it's expensive How are you feeding the loop? 450 or 300 ohm line is best. If your going to use it on multiple bands stay away from coax. You will need a good outdoor Balun that the window line will hook to then you feed the bottom of the Balun with a short run of RG8 or 214. The impedence matcher in your K3s ( PLEASE tell me you ordered it with one, some people call it an antenna tuner ) will handle this setup very sweetly !

My hope is that the 7300 is an excellent radio- so that it drives the price down for some of the radios I want to own. I'm not into the knobbed radio tradition, so the 7300 isn't for me. But if it's great, we might see a little price drop on other SDRs. That's my taske.

If the knee is 250 Hz wide at the 3 dB points then measuring the 6 dB points may be 370 Hz wide. So without the position of the filter where the measurement takes place, the number relating to bandwidth is inadequate to describe the filter. There is really no standard with regard to filter measurements, thus the value is simply arbitrary. Yes a given filter can be 250 Hz at the 3 dB points, can also be 370 Hz at the 6 dB points and also 500 Hz at the 18 dB points. So........what is the bandwidth of the filter? 73 Bob, K4TAX K3S, s/n 10163 On 2/10/2016 5:49 AM, Arie Kleingeld PA3A wrote: > Hi Dick, > > Just do it.

In that case your K3 is transmitting to one of the main ANT1 or ANT2 ports and it receiving from RX ANT IN port.

Hi Bill, Thanks for posting. My hope is that the 7300 is an excellent radio- so that it drives the price down for some of the radios I want to own. I'm not into the knobbed radio tradition, so the 7300 isn't for me. But if it's great, we might see a little price drop on other SDRs. That's my taske.

I have to say I'm very surprised and impressed at how well it works. I'm in the process of buying the newer/faster version and a metal shielded case. The Plan is to mount the RASPI case inside a rugged enclosure having a +12v DC to DC converter to +5V AND my +12v powersupply mounted. The idea is to have something I can take mobile. The only downside is the cost. For around $200 I could have a laptop that is faster + does more but also weighs more and has more RFI. The Pi with a used thrift store monitor, keyboard, mouse, I'm right at $100 without the DC-DC converter (running an AC linear converter aka Wall wart). I need to think about it some more. The end goal is something around 30w mobile without spending a fortune. The Raspberry Pi has been impressive so far.

For someone running in a contest, those are meaningful settings where is is *desired* to have the DSP and roofing skirts concurrent for sharp adjacent channel rejection. As to where those numbers came from they are the exact same filter (different mounting) as the INRAD 8 MHz 400 and 250 Filters for the Yaesu MP series. Those are part of a *cascade pair* with a 455 kHz IF filter that give razor sharp performance at 400 and 250 bandwidth, where the pairs really are 400 and 250. In the MP you put the "400" filters in the 500 slots. The MP skirts are still going down at -100 dB. I've never been able to measure the bottom. In any event, E's use of the 8 MHz as a roofing filter makes perfect sense. When needing very narrow settings, the DSP skirts inside the 350 roofer's skirts works well enough for me so far. 73, Guy K2AV On Wed, Feb 10, 2016 at 8:32 AM, Bob McGraw K4TAX wrote: > Filter bandwidth is defined by two points either across the top or at the > knee of the filter.

My use of 12 meters is seldom so it wasn't very high up on the list of things to track. When I was reminded of it while listening for VP8STI recently, I did a little more snooping and realized it was actually splatter from a BC signal at the low edge or slightly below the 12 meter band, centered about 24.89 mHz but audible from 24.87-24.91 mHz. The distorted splatter is audible as a BC station, all talk, no music, but not clear enough to decipher any ID. A few days ago I decided to try to pinpoint the source, so listened to the RFI on one ear while scanning the AM and SW bands with the sub RX on the other ear. But I could find no matches, though did find the splatter popped up centered on these additional frequencies: 813 kHz 996 kHz 2.820 mHz 3.626 mHz 19.4 mHz Figuring it must be an FM BC station, I started going through a list of Delaware FM stations and on the third one, 91.1 mHz, matched the audio peaks to my splatter. Further research determined this was a public radio station with a transmitter on a commercial tower just a half mile west of my QTH! While I of course was aware of the tower, which I knew to carry a couple of cell sites and trunking radio, I hadn't been aware of the FM station, which has apparently been there about 2 years. FCC data shows it has 2.1 KW ERP. I had not had any previous issues with the site over the past 17 years. Thinking that mixing or rectification might be produced either at the TX site or on my own QTH, I decided to track with my mobile rig, an IC-706 MK2G. But there was NO evidence of the splatter on the 706. Further debugging found that I was hearing the same splatter on BOTH of my K3 radios (no. 3021 and 3057). Even when ALL cables are removed (only the power lead connected). Grounding or ungrounding made no change. I tried the radios on a battery but still had the RFI. Tried some ferrites on the power lead but no change. So I'm thinking now there's some internal mixing in the K3 going on, and wondering if any others have had similar issues and found any solution. 73/Jon AA1K Felton, Delaware www.aa1k.us From jim at jtmiller.com Wed Feb 10 10:09:29 2016 From: jim at jtmiller.com (Jim Miller) Date: Wed, 10 Feb 2016 10:09:29 -0500 Subject: [Elecraft] 160 meters RX antenna for K3 advice In-Reply-To: References: Message-ID: Regardless of which RX antenna you chose make sure to detune your transmit antenna when receiving.

I used Inrad 250Hz filters in my Yaesu FT1000MP Mark-V and they worked great on RTTY but I found the 250Hz setting to be too narrow on my K3S. Is anyone doing this? John KK9A RLVZ at aol.com RLVZ at aol.com Wed Feb 10 00:05:30 EST 2016 A question regarding roofing filter "configuration bandwidth" settings on the K3: The factory default roofing filter "configuration bandwidth" setting is to set the 250hz filter at a setting of "250". Therefore, the 250hz roofing filter will engage at the same time as the 250hz DSP filter. However, since the 250hz roofing filter has an actual BW6 of 370hz, aren't there times when it would be more beneficial to have the "configuration bandwidth" of the 250hz roofing filter set to 350 or 400? I'm thinking this may be especially true when operating RTTY since the average RTTY bandwidth is aprx. 370hz. Perhaps there are times when this would be beneficial when operating other modes as well? Likewise, the 400hz roofer has a BW6 of 450hz, so perhaps for certain modes a "configuration bandwidth" setting of 450 rather than 400 could be beneficial as well? If anyone is wondering where I'm getting the term "configuration bandwidth" from, it's a configuration heading on the K3 Utility programs filter configuration page.

I have to say I'm very surprised and impressed at how well it works. I'm in the process of buying the newer/faster version and a metal shielded case. The Plan is to mount the RASPI case inside a rugged enclosure having a +12v DC to DC converter to +5V AND my +12v powersupply mounted. The idea is to have something I can take mobile. The only downside is the cost. For around $200 I could have a laptop that is faster + does more but also weighs more and has more RFI. The Pi with a used thrift store monitor, keyboard, mouse, I'm right at $100 without the DC-DC converter (running an AC linear converter aka Wall wart). I need to think about it some more. The end goal is something around 30w mobile without spending a fortune. The Raspberry Pi has been impressive so far.

Pulleys yes. Cord at a marine store will be expensive. Here's a link to the company that makes great antenna rope that is resold by several large ham vendors. 3/16-in is enough for strength, but 5/16-in is easier to grip if you need to pull it to put a lot of tension on it. http://www.synthetictextilesinc.com/supportham.html > I would recommend using hard drawn copper for the wire rather than > THHN. You can find THHN at your local DIY store. For hard drawn > copper, look at The Wireman www.thewireman.com. The only issue with THHN is that it stretches if under load. I have high dipoles under about 100# tension, and I have to trim them every few years. Another way to do hard drawn copper is to buy #8 bare copper at your local big box store and stretch it yourself. Cut a few hundred foot length, tie one end to a tree or telephone pole, the other end to a trailer hitch, and pull VERY slowly until it breaks. The result is hard drawn copper that is 15-20% longer. Before you commit resources to a loop, take a look at the antenna planning applications notes on my website. k9yc.com/publish.htm In general, low horizontal antennas have poor efficiency. Antennas that lack common mode chokes at the feedpoint are noisy on RX, and it's not practical to choke most non-resonant antennas. If ground conductivity is good in your area, a roof-mounted multi-band vertical could be an excellent choice. Study the FCC map. To choose a vertical, study the N0AX/K7LXC report on their measurements of the performance of a dozen or so HF verticals. Available from Champion Radio Products. Well worth the $35 or so that it costs. While you're there, also buy the report on tri-band Yagis -- you'll benefit when buying something to put on that tower when you get around to it. This work was done about 15 years ago, but the laws of physics don't change. :) N0AX is now editor of the ARRL Handbook and the ARRL Antenna Book -- he's a fine engineer who really knows his stuff. https://www.fcc.gov/media/radio/m3-ground-conductivity-map 73, Jim K9YC From jz73 at verizon.net Wed Feb 10 12:10:35 2016 From: jz73 at verizon.net (Jon Zaimes) Date: Wed, 10 Feb 2016 12:10:35 -0500 Subject: [Elecraft] 12 meter K3 RFI from nearby FM station In-Reply-To: <56BB5505.1090901@gmail.com> References: <063c01d16413$90fb9ca0$b2f2d5e0$@verizon.net> <56BB5505.1090901@gmail.com> Message-ID: <064b01d16425$f5a9d290$e0fd77b0$@verizon.net> Thanks for the tips. Any filter likely would have to be inserted internally, since I am getting this RFI without any antennas connected to the radios.Unless it is coming in on the 12v power cord, which is still a possibility. I only tried a couple ferrites and they may not have been the right one for choking out the FM signal. I did observe that I am only hearing it on the main receiver in my K3 that has a sub RX, but not on the sub RX. Also, while checking for this, and then going back to the main RX, the RFI signal on the main RX was greatly reduced. Perhaps a relay contact issue. It is still just as strong as previous on my other K3 (which has no sub RX). Toggling through PRE and ATT did not eliminate it (though changed signal level as it would for any signal). 73/Jon AA1K -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Vic Rosenthal 4X6GP/K2VCO Sent: Wednesday, February 10, 2016 10:20 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] 12 meter K3 RFI from nearby FM station Jon, I had a similar problem with a 50 kW AM BC station a few miles away.

It was fed through a ferrite bead balun. Power output was 600 watts. The rx antenna was a K9AY and one side of the rx antenna was about 6' from the radial! UGH! I 1) used rx protection; 2) decoupled the tx antenna by a relay in the coax at the 1/4 wavelength point; 3) used ferrite bead chokes on the feed line of the rx antenna, at the antenna and at the rig.? The K9AY loop has a broad rx pattern so when I set it up, it was orientated for the noise source to be in the null. I tried a magnetic type loop and it seemed to work ok but the "AY" loop was better BUT I could play with diversity reception and occasionally that made the difference between hearing and making a Q. My ON4UN low band handbook is highly dog-eared and I did manage over 150 countries at that QTH (now I am in the country).

Message-ID: I agree fully with Jerry (his message below). Good service costs money, which can be supported only through service-based charges or product revenues. Including service costs in product pricing acts as a form of distributed-premium insurance for all of us. So, while in my view Elecraft products aren't cheap by any means, for me the net value has been and continues to be outstanding. I also agree with Jerry's statement that this level of service is nearly unique. All around us consumer companies attempt to cast the service burden on the customer - self-checkout at supermarkets is one example, self-checkin at airline counters is another, pump-your-own gas, and so on. The apotheosis of this trend came for me when on a United Airlines flight the passengers were asked to clean out the seat back pockets to tidy the aircraft for the next flight of passengers. This, from an airline that no longer gives us peanuts (either literally or metaphorically.) I remember a sign I once saw in a high-end telescope shop: "Buy the best first and cry only once." Amen.

The day that radio costs get to the point of being disposable we'll see the quality and quantity of support drop to primarily community and self help. For me personally it's a pleasure to support Elecraft and their products primarily because they are aggressive to engage me in resolving any issue I may experience.

From my perspective, it seems like the cost of radios is driven primarily by what it costs to build, sell, (and with some manufacturers, support them). This is clearly Elecraft's biz philosophy -- prices are determined by those costs, and Elecraft minimizes sales costs by selling direct to as much of the world as practical. Radios will get cheaper when they get cheaper to build and sell. That can happen when new technology makes them less expensive to build, but it can also happen as quality is reduced (the bottom of the barrel Yaesu, ICOM, and direct sampling rigs are great examples). My advice is that if you want to spend less for a rig, look for a top quality used rig that's a generation or two old. My K3s were the first new rigs I bought in nearly 30 years; prior to that, I used rigs like a TS850, Omni V, and FT1000MP that I bought used, all for a fraction of their initial cost. Today, a used TS590 would be a great choice, or if you're a bit more flush, a used K3. 73, Jim K9YC From k2asp at kanafi.org Wed Feb 10 12:56:23 2016 From: k2asp at kanafi.org (Phil Kane) Date: Wed, 10 Feb 2016 09:56:23 -0800 Subject: [Elecraft] 12 meter K3 RFI from nearby FM station In-Reply-To: <56BB5505.1090901@gmail.com> References: <063c01d16413$90fb9ca0$b2f2d5e0$@verizon.net> <56BB5505.1090901@gmail.com> Message-ID: <56BB79C7.2060208@kanafi.org> On 2/10/2016 7:19 AM, Vic Rosenthal 4X6GP/K2VCO wrote: > You would need a low-pass filter in your case.

That does make it more complicated. The fact that you get it on the main but not the sub points to the T/R switch, since the sub receiver does not go through the T/R switch if the sub is set to AUX to use either the non-transmit antenna or the BNC input. If you don't know, turn on the sub and hold BSET -- you will see either MAIN or AUX. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 10 Feb 2016 19:10, Jon Zaimes wrote: > Thanks for the tips. > > Any filter likely would have to be inserted internally, since I am getting > this RFI without any antennas connected to the radios.Unless it is coming in > on the 12v power cord, which is still a possibility.

Any filter likely would have to be inserted internally, since I am getting this RFI without any antennas connected to the radios.Unless it is coming in on the 12v power cord, which is still a possibility. I only tried a couple ferrites and they may not have been the right one for choking out the FM signal. I did observe that I am only hearing it on the main receiver in my K3 that has a sub RX, but not on the sub RX. Also, while checking for this, and then going back to the main RX, the RFI signal on the main RX was greatly reduced. Perhaps a relay contact issue. It is still just as strong as previous on my other K3 (which has no sub RX). Toggling through PRE and ATT did not eliminate it (though changed signal level as it would for any signal). 73/Jon AA1K -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Vic Rosenthal 4X6GP/K2VCO Sent: Wednesday, February 10, 2016 10:20 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] 12 meter K3 RFI from nearby FM station Jon, I had a similar problem with a 50 kW AM BC station a few miles away.

It will work back and forth in the wind and as trees move. The constant flexing will take its toll on the wire. A stranded wire with insulation I have found preferred and lives longer. Also, use large diameter pulleys to keep the bending to a minimum. With a fixed terminating point and three pulleys, forming somewhat of a square, only one counter weight is required at one corner to keep the wire tight. And yes, feed it with a balanced line of your choice. Do bring it all the way into the house, thus avoiding any coax runs to the balun or matching network. On QRZ.COM, you can see my balanced line section from the tuner, running up the wall, through the ceiling, to the attic and to the outside. Lightning protection is on the outside before the line enters the house. 73 Bob, K4TAX K3S, s/n 10163 On 2/10/2016 12:37 PM, Nels Nelsen wrote: > Copper is fine for conductivity but: > > multistrand copper coated steel > > is longer lasting.

If the mix product result is 8,215 Mhz you can hear it. I'm 3 km away from a BC tower hosting 10 station with >20kw each. Used SDR-radio on the K3-IF at 8,215 Mhz to identify the FM stations. That was easy, stereo and even RDS could be decoded via the K3-IF. the "mixing" frequencies could quickly be found. You can calculate where 91,1 pops up For the 3th VCO harmonic ((BCfreq-8,215)/3)-8,215 and ((BCfreq+8,215)/3)-8,215 That is 19,413 Mhz and 24,890 Mhz (you already knew :) ) For the 5th 8,362 Mhz and 11,648 Mhz For the 7th 3,626 Mhz and 5,973 Mhz And so on, With a strong enough signal from a generator, mixing of the 11th harmonic could be detected. I have only seen the BC mix phenomena when using the RX-in with MainRx and the SubRX on separate (wideband) antenna. When using the RX-in, the K3 LPF is bypassed and with the Subrx, there is no LPF in the KRX3 ! The LPF in the main antenna circuit has enough attenuation to stop BC FM leakage to the K3 mixer in my situation. Since you have such a strong signal on 91.1 Mhz Check if the products can be heard with the suggested external LPF connect to a dummy load on Ant1 (K3 LPF is inline too) If that is still the case, the antenne input(s) is probably not the route the BC signal makes to the mixer. Hope you find a solution. 73 Hugo pa4la From wunder at wunderwood.org Wed Feb 10 16:08:18 2016 From: wunder at wunderwood.org (Walter Underwood) Date: Wed, 10 Feb 2016 13:08:18 -0800 Subject: [Elecraft] 12 meter K3 RFI from nearby FM station In-Reply-To: <56BB70D2.7050102@blomand.net> References: <063c01d16413$90fb9ca0$b2f2d5e0$@verizon.net> <56BB5505.1090901@gmail.com> <001e01d1641d$f90bbbe0$eb2333a0$@biz> <56BB70D2.7050102@blomand.net> Message-ID: <44F60E9A-1144-4983-ABC8-6B6F914BEA5B@wunderwood.org> A long time ago, I visited the transmitter room at the top of One Shell Plaza in Houston.

I can replace broken 14 AWG THHN 3 times for the price diff... IF it breaks... and I will simply use a non-stretching down-line on the tension weight and monitor its descent toward the ground to determine if and when to trim the loop back and re-terminate. I'd use that snazzy, 30% copper over steel stuff if I didn't have the system/access to maintain/replace the loop and I needed it to stay put for years and years... the insulation vs. bare wire has some measurable impact on radiation characteristics, but at this point, I'll just get a loop in the air so I can get on the air when I finish assembling and testing my K3s. Thank you and ALL of y'all for y'alls help and opinions, et al.

This goes way back to the original "International Radio" as a spin off of the Fox Tango club. Yaesu (and Kenwood) specified their filters for operational bandwidth - with two filters (1st and 2nd IF) in cascade. Thus 250 Hz at - 3dB in each filter/IF resulted in an overall 250 Hz at -6dB for the two in cascade. A *single* 250 Hz filter - typically the 1st IF - was a very good RTTY filter since it had a 370 - 400 Hz bandwidth and relatively low group delay (phase distortion) at the "corners". Unfortunately, that doesn't quite work with the K3 where the DSP is set to 250 Hz because the DSP has very sharp skirts (high levels of phase distortion). However, it will work if the "250 Hz" filter is set to kick in at 390 Hz in RTTY and the DSP is also set for 390 Hz. You achieve a very sharp 390 Hz bandwidth (the DSP "cleans up" the skirts of the IF filter) with minimum required bandwidth for 45 baud 170 Hz shift RTTY. Going back to the original question in this thread ... setting the 400 Hz filter as a 450 Hz and the 250 Hz filter as a 370 Hz filter results in the sharpest skirts with overall bandwidth (at - 6dB) roughly the same as the 450/370 settings. That may not be enough difference to justify the cost (price and "slot") of both IF filters and is one reason I prefer the "400 Hz" along with the Elecraft 200 Hz - 5 pole filter when it is available. I don't see enough improvement with the "250 Hz" filter in RTTY to justify both. 73, ...

If you can support it so it will not flex, you can tension it greater than plain copper. But it 'remembers' the coils it had on the wire spool and will spring back to those coils if allowed to remain free and untensioned. If you pull it while it has a kink in it, the game is over, that kink will become a spot for failure. That is part of why I prefer hard drawn copper wire for my antennas. I use stranded #14. The stranded will endure more flexing than solid wire, and will not kink as easily as copperweld. Any antenna wire will be subject to some flexing (from wind if nothing else), so plan on that - that is especially true if you are using trees as supports. Even though you may have a system that allows the trees to move in the wind without stressing the antenna wire, there will still be flexing of the wire when those trees move. Those reasons are why I use stranded hard drawn copper wire. All my antennas are resonant. For those who are using non-resonant antennas, stranded copper wire (not hard drawn) will usually suffice because some elongation of the wire is not likely to hurt anything. So the bottom line answer is "it all depends" on your planned antennas and how much variation you can tolerate. 73, Don W3FPR On 2/10/2016 6:42 PM, Jim Brown wrote: > On Wed,2/10/2016 10:37 AM, Nels Nelsen wrote: >> multistrand copper coated steel is longer lasting. > > Not in my experience -- my neighbor hung a dipole strung with > copperweld (what you're describing, I think) in some trees with > tension on it and with pulleys and weights to deal with tree sway.

Jim makes some very good suggestions for 'taming' that problem. It would be very difficult to cure the K3 of the "pin 1" problems. For those who are not familiar with the "pin 1" problem, that is a situation where the shields of interconnecting cables are connected to the circuit boards rather than directly to the outside of the transceiver enclosure. That allows any pickup on attached cables to be imposed into the boards of the transceivers. In days of old when we mounted all connectors to the enclosure rather than to the circuit boards, the enclosure itself provided a shield for whatever trash was picked up by the external wiring - because those trash signals would flow on the 'outside' of the enclosure and not affect the circuits inside. With modern transceivers where cable jacks are connected to the ground plane of the circuit boards rather than to the enclosure, the external signals are coupled to the ground plane of the internal boards, and will couple the offending signals into the transceiver. In other words, "board ground plane" does not equal "ground" - variations in the ground plane reference will cause "funny happenings" within the interior circuits. In other words, the enclosure does not offer a sufficient shielding effect for the circuits inside the enclosure. The K3 is not alone in this problem, it is shared by any transceiver that does not ground the connectors directly to the enclosure. 73, Don W3FPR 73, Don W3FPR 73, Don W3FPR On 2/10/2016 6:57 PM, Jim Brown wrote: > Yes, this hit me between the eyes as well.

Jim makes some very good suggestions for 'taming' that problem. It would be very difficult to cure the K3 of the "pin 1" problems. For those who are not familiar with the "pin 1" problem, that is a situation where the shields of interconnecting cables are connected to the circuit boards rather than directly to the outside of the transceiver enclosure. That allows any pickup on attached cables to be imposed into the boards of the transceivers. In days of old when we mounted all connectors to the enclosure rather than to the circuit boards, the enclosure itself provided a shield for whatever trash was picked up by the external wiring - because those trash signals would flow on the 'outside' of the enclosure and not affect the circuits inside. With modern transceivers where cable jacks are connected to the ground plane of the circuit boards rather than to the enclosure, the external signals are coupled to the ground plane of the internal boards, and will couple the offending signals into the transceiver. In other words, "board ground plane" does not equal "ground" - variations in the ground plane reference will cause "funny happenings" within the interior circuits. In other words, the enclosure does not offer a sufficient shielding effect for the circuits inside the enclosure. The K3 is not alone in this problem, it is shared by any transceiver that does not ground the connectors directly to the enclosure. 73, Don W3FPR 73, Don W3FPR 73, Don W3FPR > On 2/10/2016 6:57 PM, Jim Brown wrote: > Yes, this hit me between the eyes as well.

I built a dipole one time and fed it with the 450 Ohm window line everybody likes to use. I twisted the ends of the window line and crimped a couple of terminals on the ends. If it was going to be a permanent antenna I would have soldered it. Two years later when I took it down I disconnected the window line from the 1:1 current balun and the terminals came off in my hand. Apparently when I twisted the strands before crimping the connectors I removed some of the copper. The steel wire underneath had rusted to dust a good six inches back. No more window line here, doesn't matter who sells it, and no more copper weld. On 2/10/2016 5:59 PM, Don Wilhelm wrote: > Copperweld is "nasty" stuff IMHO.

This crystal filter remains engaged as the DSP bandwidth is narrowed, to the point where another crystal filter's "configuration bandwidth" is reached. In choosing the configuration bandwidth, one consideration is the cascade effect of the crystal and DSP filter bandwidths. In general, the cascade bandwidth will be less than either of these two filter bandwidths. The extent to which this is true depends on how close the two filter bandwidths are to one another. This reduced cascade bandwidth is the underlying reason for the KFL3A-250 crystal filter from INRAD being called "250 Hz" but actually measuring about 370 Hz at -6 dB and about 310 Hz at -3 dB. (See http://www.elecraft.com/K3/K3_filter_plots.htm.) This filter was originally designed for the Yaesu first IF and intended to be used in conjunction with another "250 Hz" filter in the second IF. Each filter is actually wider than its marketing name because when the two are cascaded, the resulting bandwidth is about 250 Hz. The cascade effect of the K3 crystal and DSP IF filters is less than the Yaesu and Kenwood cases where both filters were crystal filters, each with a somewhat "round" shape. The K3 DSP filter is more "square" in the transition between passband and stopband. Since the K3 DSP bandwidth is continuously variable, it becomes more important to consider this cascade effect because it may or may not be significant depending on how close the crystal and DSP filter bandwidths are to one another. It is also more important with the K3 to be aware of the actual crystal filter bandwidths. For RTTY operation, the minimum cascaded bandwidth should be about 400 Hz. This is because modern software decoders, e.g., MMTTY and 2Tone, use algorithms that make use of the sidebands of each tone in order to minimize error rate. Using narrower IF filters, including the DTF, in the radio attenuates these useful sidebands. For the same reason, the K3 (and, Icom) dual-tone filter removes sideband information that could be used by the decoder to improve copy. Anecdotally, in pileup and QRM situations such as DXpeditions and contests, I've found a cascaded IF bandwidth of 400-500 Hz to be superior to the narrower bandwidths, including the DTF, that I used several years ago. Accordingly, I've chosen the INRAD 500 Hz 8-pole filter for CW and RTTY, setting my DSP bandwidth to 400-500 Hz as desired. I think this gives marginally better, and more versatile, filtering than the KFL3A-250. For very heavy QRM CW situations, e.g., 160 meter contests, the 5-pole 200 Hz crystal filter is useful. Ed W0YK ____________________________________________________________________________ ___ Dick K9OM wrote: A question regarding roofing filter "configuration bandwidth" settings on the K3: The factory default roofing filter "configuration bandwidth" setting is to set the 250hz filter at a setting of "250". Therefore, the 250hz roofing filter will engage at the same time as the 250hz DSP filter. However, since the 250hz roofing filter has an actual BW6 of 370hz, aren't there times when it would be more beneficial to have the "configuration bandwidth" of the 250hz roofing filter set to 350 or 400? I'm thinking this may be especially true when operating RTTY since the average RTTY bandwidth is aprx. 370hz. Perhaps there are times when this would be beneficial when operating other modes as well? Likewise, the 400hz roofer has a BW6 of 450hz, so perhaps for certain modes a "configuration bandwidth" setting of 450 rather than 400 could be beneficial as well? If anyone is wondering where I'm getting the term "configuration bandwidth" from, it's a configuration heading on the K3 Utility programs filter configuration page.

In reading the original post, he was getting splatter on 12M which would indicate the antenna was connected. Nothing mentioned about the Preamp being on or off. Normally for 12M it is on, maybe PRE II is on as well. There are precautions stated n the manual in this regard. As a result of any reactive input termination, it could be oscillating. If so, all bets are off. Birdies abound! Then disconnecting "all cables" and I don't take this to mean antenna disconnected as well, but powering from a battery still show evidence of the problem. I could see with the antenna connected, corrosion on the antenna element(s) or feed line connectors acting as a diode or even a metal gutter, downspout and etc. and being excited by the FM carrier plus subcarrier/pilot making it appearance as multiple birdies modulated by the FM audio. However, with "everything" disconnected except for power cable and the problem remain, very strange. The K3S is built better and shielded better than this. 73 Bob, K4TAX On 2/11/2016 11:03 AM, Alan wrote: > On 02/10/2016 03:57 PM, Jim Brown wrote: >> Yes, this hit me between the eyes as well.

I would not expect the integral shielding of the K3 radio to be that poor. Most of the box is metal and most connectors are mounted on the metal box. For an AM BC station, I would not think anything related to the carrier frequency, harmonics or parasitic , to have anything near 14 MHz existing. So, it seems there are issues internal to the radio which contribute to the spurious reception. The worst thing causing spurious is near field dis-similar metals, in effect diodes, excited by the RF. I've found in more than one case, the metal fence around the BC tower and guy anchor points to be a contributor. Better defined as poor site maintenance. In another case, poor lighting conduit bond to the BC tower and also metal gutters and downspouts around any build in the near field causing the same effect. These will radiate like crazy at the resonant point. For example, a 8 ft downspout attached to a 33 ft metal gutter makes a nice 20M inverted L. That 1100 watt station wouldn't just happen to be on 890 kHz or close by would it? If one is experiencing activation of the front end protector, then a coax stub at the offending frequency should be of great assistance. The only issue is the length of coax required to make the stub. {about 125 ft or so depending on BC frequency and velocity factor of the coax} As to insertion of filters, unless attention is paid to negate the common mode current, i.e current induced on the feed line from the BC station, then the current simply flows around the outside of the expensive filters and they are not effective. The problem is solvable, identifying it is the challenge. That will take some detective work. 73 Bob, K4TAX On 2/11/2016 11:33 AM, Chris Hallinan wrote: > I have a similar problem.

(2) Wrap the tree with a tarp or heavy cloth to protect its bark from damage. (3) Then wrap it with 2" nylon webbing at least 3 times. Use a water knot to join the webbing. Leave the knot facing the load and pull the rest of the loops out to a carabiner or quick link rated for the expected load. This arrangement gives you a chance of being able to untie the know when you are finished. (2" tubular webbing is rated at 4000#. If you pull two loops, that is 4 strands and 16000#. Derate by 50% for knots, bends around carabiners etc and get 8000#.) (4) If you are breaking things, such as #8 copper wire, cover them with blankets to minimize the danger of having them snap through the air. (5) Keep everyone far enough away so flying wire won't hit them, or keep them in a closed vehicle. 73 Bill AE6JV On 2/11/16 at 6:34 AM, edauer at law.du.edu (Dauer, Edward) wrote: >I wondered what 700 or 800 pounds of shear force would do to an >automobile frame, assuming attachment to a suitable bolt >somewhere.

I'm assuming this means nothing at all plugged into the back of the rig -- no control, no audio, nothing to the BNCs, nothing to the Aux power jack. By all means choke the 12V DC cable. Since the RFI is VHF, this IS an application for a "string of beads" choke. #43 clamp-ons would be the weapon of choice, either single turn or two turns. #31 would also work. What you want is a clamp-on with two turns through it, a short length of the power cable, then another clamp-on with two turns, a short length of cable, then another clamp-on with two turns, and so on. Select the size of the clamp-on to fit the number of turns. Turns should be widely spaced. Do NOT run two turns through a string of clamp-ons -- that will take the resonance too low in frequency to work at 90 MHz. You can see data for the choking Z of individual Fair-Rite parts with one, two, and three turns on the data sheets for those parts. Click on the part number in the table of parts to get that data sheet, then scroll all the way down for the impedance plots. You may need to click on that to get the three turn plots. 73, Jim K9YC From w0eb at cox.net Thu Feb 11 15:41:31 2016 From: w0eb at cox.net (Jim Sheldon) Date: Thu, 11 Feb 2016 20:41:31 +0000 Subject: [Elecraft] OT FS -K3 #5027 with many options Message-ID: My wife bought me a new K3S for my upcoming birthday so my original K3 is up for sale.

Bind LOW on the tree to make the pull closest to the anchor of the tree (the roots). Vehicle frames are much stronger than a piece of typical (for antennas) copper wire, no worries. Even the smallest car can handle the strain of a SMALL trailer (or passengers of large girth), BUT one should move slowly to not shock load the wire or vehicle AND (in addition to the excellent advice given) the safe zone is any place further away than the total length of the wire plus at least 20% (factor in stretching) since it may whip upon snapping. While it's slightly possible that it could snap in multiple places and become airborne, distance is your friend. When in doubt, use another tree as a shield PLUS distance and safety equipment (hard hat, goggles etc.). Rick nhc On 2/11/2016 12:13 PM, Bill Frantz wrote: > Trees are quite strong.

Sometimes that actually works out. ;-) The tension that is suddenly released, has to dissipate SOMEwhere, the trick is to not be in the way when that happens. Copper, because it is soft, uses less energy to stretch, but ... hanging cloths on the wire is good because it's a visual indicator that the wire is still intact (the cloths are not on the ground) as well as acting as a shock absorber should the wire fail.

A piece of copper wire which is thoroughly annealed will allow stretching of 62% before it fails at the ductile-brittle transition. This transition point is temperature dependent so a warmer day is better. Once you have stretched the copper you can stretch it again as long as you anneal it first. I did not look up the annealing temperature of copper. Thus, for safety's sake, stretch the line to a 50% increase or less to avoid having it part on you. Copper alloys allow for less ductility so decrease the amount of stretching to avoid an accidental parting. GL, Kevin.

It should be no different than adding a USB to serial adapter (because that is what is inside the KIO3B). I suspect that "USB Composite Device" is what you might be looking for - is there a COM Port number associated with it? That kind of stuff is computer dependent. If you did not obtain anything reasonable, unplug the USB cable from the computer and try another USB port. Wait until the computer indicates that the device is ready to use. I know that works on Windows 7 and Windows 10 (should work in Win8). If you are using XP, that may get a bit 'dicey' and you may have to explicitly load the FTDI driver. Once you know the COM port that the computer has assigned, just tell LP-Bridge to use that COM port. 73, Don W3FPR On 2/11/2016 4:39 PM, N2TK, Tony wrote: > I tried installing the USB cable from the K3 to the PC.

That can be computer dependent, so no specific advice can be given. Select that soundcard in your data mode application and you should be "good to go" other than adjusting the soundcard levels. Use DATA A rather than SSB because the K3 automatically turns off compression and sets the TX EQ flat.

It should be no different than adding a USB to serial adapter (because that is what is inside the KIO3B). I suspect that "USB Composite Device" is what you might be looking for - is there a COM Port number associated with it? That kind of stuff is computer dependent. If you did not obtain anything reasonable, unplug the USB cable from the computer and try another USB port. Wait until the computer indicates that the device is ready to use. I know that works on Windows 7 and Windows 10 (should work in Win8). If you are using XP, that may get a bit 'dicey' and you may have to explicitly load the FTDI driver. Once you know the COM port that the computer has assigned, just tell LP-Bridge to use that COM port. 73, Don W3FPR On 2/11/2016 4:39 PM, N2TK, Tony wrote: > I tried installing the USB cable from the K3 to the PC.

Mine is a custom true condenser mic, suspended from a shock-mount on a Heil PL2T boom, using a Canare XLR to feed the audio signal to a Mackie ONYX Black Jack, 2-channel preamp, used for -48vdc phantom power and impedance boost. There is a pop filter fitted in front of the mic. The boom can be swung clear when not in use. The mic/pre is powered by the USB connection to my shack/studio computer. (The outgoing audio can be recorded realtime whether for recording voice-over OR outgoing traffic via the transceiver. The Mackie is connects to the transceiver via the rear mic in jack and a TRS cable. The Mic: 1) Beginning with the body and frame of a donor MXL-990 condenser mic. 2) Custom large diameter capsule chosen specifically for the build. 3) Custom PCB, stuffed and soldered using 4% silver solder, and electrically tested, thence all high impedance connections triple washed and coated with special conformal coating to prevent corrosion. 4) Custom capsule pedestal designed to electrically and physically isolate capsule from the rest of the mic. 5) Replaced head-basket with one designed to break up audio standing waves. 6) PCB has pattern switch allowing omni for recording or cardoid for radio work. 7) Body and frame are filled with vibration damping material. 8) Frequency response was adjusted via component changes to provide a low-cut to reduce power waste and reduce band-width on SSB. Frequency response was adjusted further on the high end to smooth and roll off the highs. 9) Mic body, and shock mount custom powder coated to match the black in the boom and almost a match for the Elecraft chassis. Audio/electrical testing reveals a near perfect neutral sound, and an almost pure voltage signal and low current to reduce load on the K3s audio input circuitry. Sound is absolutely amazing... better than some $2K+ condenser mics I've used. All for less than the cost of some of Heil's dynamic mics. I built this double duty to perform both jobs with minimal space consumption. I have very little space to work with for my "shack". A lot of detail work, but the results are nothing short of phenomenal. I was told a condenser could not be used for a HAM mic. That was a mistaken assumption. If you are interested in getting into a mic project like this, email me offline and I'll turn you on to the company that provided me the PCB kit and the capsule, and assisted me in tailoring it for dual use. Y'all have a good night! ______________________ Clay Autery, KG5LKV MONTAC Enterprises (318) 518-1389 On 2/11/2016 11:20 PM, grif80128 at comcast.net wrote: > As a new owner of a K3S, I'm wondering what the mix of microphones being used is.

Working distance to the face of the mike is 4" to 5" on axis {one fist} so as not to enhance bottom end due to proximity effect, typical of dynamic mikes. The MIC SEL is set for FP.H with the mike gain at 40 and the COMP at 15. The PR 781 is mounted on a small spring loaded desk boom that allows for easy placement for operation and moves easily out of the way when not needed. I did make my own mike cable using some Belden 8771 which is 3 conductor shielded cable connecting between the XLR connector and the Foster connector. The cable shield connects at the radio end only. 73 Bob, K4TAX K3S, s/n 10163 On 2/11/2016 11:20 PM, grif80128 at comcast.net wrote: > As a new owner of a K3S, I'm wondering what the mix of microphones being used is.

That is correct although with the K3/K3S since the Elecraft mic RFI change it should not matter (both pin 7 and pin 8 are connected to the "ground" foil on the front panel circuit board). Early K3 front panels included an RF choke in the mic *and* PTT returns which made the "pin 1 problem" much worse. With the RF choke removed (bypassed) the issue is significantly reduced but there may still be a problem if the overall station installation has any "RF on the coax." 73, ...

As to radio set-up, see page 33 of the manual for details. I use DATA A mode for PSK & other data modes. The software is usually FLDIGI, HRD/DM780 or WSJT-X which all work under Windows 10 successfully and do control all aspects of the radio. The DATA A mode is not the typical or normal USB/LSB mode in that it releases any TX EQ and CMP values used for SSB. The computer Device Manager reports the radio under "Ports (COM & LPT)" as "USB Serial Port (COM 5)". Depending on your computer, your port number may be different. Audio, PTT and CAT control of the radio is handled by the single USB cable installation. None of the rear panel connections are used other than the USB port on the radio. 73 Bob, K4TAX On 2/11/2016 3:34 PM, John Shadle wrote: > I looked in the K3S manual, and the instructions on setting up data modes > (p. 33) fail to mention the use of the KIO3B internal sound card.

I am using the K3 to send WSPR at 0.2W, band hopping but on almost continuously on one band or another. The driving program is WSTJ-X in WSPR2 mode with scheduling enabled. Whilst it always works OK to start with and I get reports, I notice that after it has run for a few 10s of minutes I get no reports. It is as if there is no o/p from the K3. If on the other hand I run at 2W and put a 10dB attenuator on the output socket, it all seems to work as expected for as long as I run it. So is this a known problem with the K3, a broken K3 or have I made a mistake somewhere?

It should be no different than adding a USB to serial adapter (because that is what is inside the KIO3B). I suspect that "USB Composite Device" is what you might be looking for - is there a COM Port number associated with it? That kind of stuff is computer dependent. If you did not obtain anything reasonable, unplug the USB cable from the computer and try another USB port. Wait until the computer indicates that the device is ready to use. I know that works on Windows 7 and Windows 10 (should work in Win8). If you are using XP, that may get a bit 'dicey' and you may have to explicitly load the FTDI driver. Once you know the COM port that the computer has assigned, just tell LP-Bridge to use that COM port. 73, Don W3FPR On 2/11/2016 4:39 PM, N2TK, Tony wrote: > I tried installing the USB cable from the K3 to the PC.

I have my existing K3 set up the way I like to use it and have saved the configuration via the excellent utility. The K3s is coming completed, I will immediately put the 100W module and the ATU in place. I currently have a sub Rx in the K3, I will move it to the K3s once I have completed upgrading the low frequency modules and perform the needed updates on the Sub Rx. I haven't done any soldering to surface mount components and need to first practice on a junk component so I may not get those soldering changes done right away. Soon, but not till I feel 100% secure I will do a perfect job. I'd like to start using the new rig ASAP but would like the setup to be like my K3 is, using as examples; my saved selections for RTTY & DSP. - Will I encounter any unexpected problems if I load my K3 configuration to the K3s and start operating? - If the answer is no, will there be any negative issues to the normal operation of the K3s if I change the configuration of the K3s to that from my K3 which has the sub Rx, if I do so before adding the sub Rx to the K3s? Or will I need to put the Sub Rx in before importing my K3 configuration? If there will be issues then I should run through all the various configuration settings and write each of them down. There's a lot to do if that's the case and it will be awhile before I get all those settings in a list. 73 & thanks, Gary KA1J From pkirley at fuse.net Fri Feb 12 12:05:39 2016 From: pkirley at fuse.net (Paul Kirley) Date: Fri, 12 Feb 2016 12:05:39 -0500 Subject: [Elecraft] K3 LCSET not working for KAT3 Message-ID: <3.0.6.32.20160212120539.01f37b28@pop.fuse.net> My K3 1322 has an original KAT3 and firmware 5.38 2.86 1.25. Last night I tried to use the LCSET feature of the KAT3 item on the Configuration menu. I have used this successfully in the past, but no luck this time. I was able to make the L and C values show on the display, but rotating the VFO knobs changed the values on the *previous* display. I could hear VFO A start to test relays as I rotated it to the right, and once I found myself changing the date after rotating VFO B and then A while the unchanged L and C values showed on the display. Exiting from LCSET did not seem to go correctly either. In order to return the KAT3 to Auto, I had to fully exit and re-enter the Configuration menu. Has anyone else had LCSET problems, or am I the only one? For the benefit of the reader, I quote the relevant manual wording, part of the KAT3 item on the Config menu: ******************** Mode LCSET allows manual adjustment of L/C settings (you must exit the menu first). When in LCSET mode, tapping ATU TUNE shows the L and C values; C is changed with VFO A, L is changed with VFO B, and ANT toggles between Ca and Ct. ******************** 73, Paul W8TM From erusst at att.net Fri Feb 12 12:16:53 2016 From: erusst at att.net (Russ Tobolic) Date: Fri, 12 Feb 2016 17:16:53 +0000 (UTC) Subject: [Elecraft] K3S Microphones In-Reply-To: <56BDD94C.5090209@blomand.net> References: <56BDD94C.5090209@blomand.net> Message-ID: <241027734.3162172.1455297413201.JavaMail.yahoo@mail.yahoo.com> I have K3 S/N 732 and use a $2 electret computer mic I bought at a yard sale. ?They had a white one that was only a $1 but I chose to go the more expensive route and buy the $2 black one to match the K3. ?My settings are -16db ?up to 400 Hz, 0dB at 800-1600 Hz, and +16 dB at 2400 up and I get good audio reports. ?After 8 years I did recently splurge and upgraded to the Koss SB-45 which works great.?Russ, N3CO From: Bob McGraw K4TAX To: elecraft at mailman.qth.net Sent: Friday, February 12, 2016 8:08 AM Subject: Re: [Elecraft] K3S Microphones I use a Heil PR 781 with great success.?

Probably...because Config Save will copy your K3 calibration constants into the K3S. You would at least need to go through all calibration steps again. I doubt the K3 Utility will even allow you to copy K3 settings into the K3S but I honestly don't know. Hopefully someone from Elecraft will respond. You do bring up a good point that it would be nice to have a Config Save Lite that would affect only common menu choices for the K3/K3S but not calibration constants and items unique to the K3. I doubt Elecraft has thought of this but it would be nice if possible. If I were you I'd go through the K3 CONFIG settings, write everything down and then manually duplicate into the K3S.

As such, the good ones tended to be expensive and often fragile. Nowadays, both optics and mic elements are manufactured using highly automated processes that provide uniformly outstanding quality at very low prices. The specs on the little RS electret mic element available for a few dollars are something one would pay king's ransom for back then. I have used the RS elements in my own mics as well as replacements in commercial applications with excellent results. 73, Ron AC7AC -----Original Message----- I have a woodworker nearby, built a perfect example of an RCA 44 - except the internals are a RadioShack electret element.

The K3 will ignore the "pipe" character in CW mode, but will end the transmission immediately when it encounters it in RTTY (FSK D) mode. The "pipe" character is the upper case character on the same key as the backslash character. You can use the "Edit CW Memories..." function in the K3 Utility to add this character to your messages. 73, Bill - NA5DX >I'm sure this has been brought up before but I've been told that there's a >hang time issue when I'm done transmitting RTTY.

Those do have computer and OS dependencies that I cannot give specifics for. In addition, how MMTTY interacts with your computer is another area that must be looked at. You must tell MMTTY which soundcard to use. Then in your Operating System, open the sound panel and set the sliders for output to about 2/3 of maximum. In the K3S, set MIC SEL to LINE and adjust the input level (MIC Gain with LINE selected) to produce 4 bars solid on the ALC meter with the 5th bar flashing. If you can achieve all that, you should be able to transmit RTTY with the K3S in AFSK A data submode. 73, Don W3FPR On 2/12/2016 5:40 PM, Irwin Darack wrote: > I am in the process of setting up a second K3S that I just built and having > difficulties setting up RTTY using MMTTY > > Using the USB Codec, I can key the rig, receive Audio in and copy RTTY, but > no Audio from the computer to the radio. > > I have the correct speaker in the computer selected (USB Audio Codec) .

There are no menu settings to accomplish that feat, you must build an adapter to route the AF and PTT and their Return paths to the appropriate pins on the K3/K3S microphone jack. The CM500 has a stereo mic plug, but the tip and ring are connected together. That is no "never mind" for the K3, but for the KX3, it does cause a problem. Without building an adapter, you can turn off bias and turn MIC BTN off, and it will work. The bias is supplied from the residual voltage of the digital voltage designed for the MIC BTN. If you find that digital voltage produces digital noise in your signal, the only cure is to build an adapter to isolate the ring from that digital voltage and if you do that, you will have to turn BIAS on for the CM500 to operate. 73, Don W3FPR On 2/12/2016 5:55 PM, grif80128 at comcast.net wrote: > Thanks for all the responses.

The K3 will ignore the "pipe" character in CW mode, but will end the transmission immediately when it encounters it in RTTY (FSK D) mode. The "pipe" character is the upper case character on the same key as the backslash character.

To receive RTTY directly on the VFO B display: 1. Tap DATA 2. Rotate VFO B to select FSK-D 3. Tap any switch to exit DATA setup 4. Hold TEXT DEC to turn on text decode 5. If you were using DISP to look at supply voltage, etc., that will override text decode, so tap DISP to exit Then just tune in RTTY signals and watch the decoded text scroll by. To transmit, you can use either a keyer paddle attached directly to the radio, or a keyboard attached to a PX3 or P3, or use your PC keyboard from within K3 Utility or KX3 Utility. Happy hunting!

I've used both since their each started and have the paid-for versions of them (the free HRD is not the same as the paid-for version). 4K3 can read/write the KX3 memories and their internal little labels. HRD can't control the KX3 memories directly, BUT it does have its own internal "favourites" (with longer labels and a hierarchical structure) which may be used to set the Tx/Rx frequencies, which I find more useful. If 4K3 implemented such functionality I probably wouldn't use HRD at all. Both applications are complex (easy to understand if you've grown up with them but far too many options at first sight if you haven't) but 4K3 is less so. Probably HRD is more complex because it is more general purpose and supports far more radios. It includes modules to do far more than 4K3 including digital modes, more logging options, rotator controls, satellite tracking etc. Both have "manuals" that explain the menus - which is not the same as explaining how to use the applications to perform specific tasks - obviously written by the developers not by users. Both could do with a "how to ..." manual. Both work fine under Windows 10 and are regularly updated to add new functionality. Because 4K3 is more rig specific, the updates seem more useful, updates to HRD seem recently to be concentrating on more peripheral functions. I hope this helps.

They do overlap on some functions, where they can do the same thing. IMHO the W4K3 is excellent for the PanaFall display of the band, and is also excellent for getting to menu functions quickly, and everything you need is one mouse click on the display. HRD is good for it?s logging program, digital modes rotor control, cluster - point and click on a DX spot and instant QSY etc etc They both talk to each other so it would be best to get both, but to save on costs get the free version of HRD. 73 John > On 13 Feb 2016, at 03:23, Clay Autery wrote: > > I would be interested to hear supported opinions as to which is better > and why between: > > Win4K3Suite and Ham Radio Deluxe. > > W4K3 is $50 > HRD is now $100 for a new license and $50 a year for support (optional) > > Go! > > PS - I would have avoided this IF I could remember how to search the > archives... maybe.

I do however, use both HRD and Win4K3. I don't run the HRD main program, but allow Win4K3 to launch and control DM780, HRDlog, WSJT-X and JT-AlertX. They all play well together and I can keep using my HRD Logbook which holds +45 years of QSOs.

One issue when comparing the onboard Codex to the outboard M-Audio Delta 44. I am running two versions of MMTTY at the same time. AXETTY set up for main receiver and using left MMTTY channel. Second MMTTY set up for second receiver and right channel in MMTTY Line out on K3 - 001 With M-Audio Delta 44 Using Line 1/2 - Left Channel Recording Level - 33 AXETTY - Main K3 receiver decoding fine all the time MMTTY - Second receiver - nothing decoded with SUB off. Decoding fine with SUB ON. I like it this way Using Codex and Cable from Delta 44 still plugged in - it doesn't matter if the other end is plugged in or pulled out of the Delta 44. Using Codex Microphone Recording level - 3 AXETTY - Main K3 receiver decoding fine all the time. MMTTY - Second receiver - nothing decoded with SUB off. Decoding fine with SUB ON. Using Codec and Cable from Delta 44 removed from the K3. Using Codex microphone Recording level - 3 AXETTY - Main K3 receiver decoding fine all the time. MMTTY - Second receiver - with SUB off decoding strong signals (>s8) from the Main receiver. Second receiver RF gain has no effect on reducing the signal on the second receiver decoding. The RF gain on the second receiver works fine as it should with the SUB ON and decoding is fine. The problem is that if I am listening to a strong signal on the main receiver and operating split mode and the receive signal in the second receiver is not strong, the decoding is a combination of both signals scrambled on the second receiver. I use the second receiver to find out the pattern and where the DX is listening. Any ideas why the crossover with the Codex? If I reduce K3 Line out any more or reduce Codex microphone recording level any more there is no signals on either receiver. Interesting that plugging in a jack in the K3 Line out solves the problem. Tnx for any feedback. Sri about all the recent KIO3B posts.

The rest of the stuff is all fluff to me - unused. I run both my K3 and TS480 from the screen by chasing the mouse. There are a couple of buttons that do not indicate as they should, and I would buy the new version if I thought the problem had been corrected. I asked HRD support and they said to buy it and I would be happy - never did directly answer my three or four simple questions. I did not buy it. I have asked a couple of other times about the button issues and never received a real answer. I would buy the new HRD immediately IF the button issues have been corrected. If not - I'll stay with the free. Digital? Very simple - I use Airlink on my 480. Super easy - turn on the SignaLink, start Airlink, and make contacts (25 Watts). To go back to SSB - just turn the SignaLink off and pick up the mic (PTT) for 100 Watts. Got carried away - sorry.

K3 Terminal is there for convenience, and while is does the job, it was not intended to be a "logger", so no serial number incrementing is possible. For FSK D, take a look at MMTTY - it can do both soundcard AFSK A and FSK D if you build a "one transistor keying device" to 'wiggle' the FSK IN pin on the K3 ACC connector. 73, Don W3FPR On 2/13/2016 10:01 AM, Peter Pauly wrote: > I'm using the K3 Terminal and FSK D mode for the RTTY contest and am doing > "okay" but have the following questions: > > 1.

You have a tuner so no internal ATU unless you want the internal automatic convenience. You have a good mike, I use one of those myself. As to filters, the standard filter is most adequate and always and one can add additional filters if desired. If you intend to operate CW perhaps a 500 Hz or 400 Hz filter would be a nice initial choice. As to the 10 watt vs. 100 watt radio, if you wish to operate lower power then the 100 watt will easily back down to 10 watts or less. However, with the somewhat compromise attic antenna, a bit more power is likely preferred. Thus I'd opt for the 100 watt version. As to 2 meter operation, unless you intend to work SSB, I'd opt for a dedicated VHF/UHF FM radio for repeaters and FM simplex. So in summary, K3S-100 either F or K being factory assembled and tested or the kit. 73 Bob, K4TAX K3S-100-F, s/n 10163 On 2/13/2016 11:28 AM, Tom Brohl wrote: > Hello Elecraft subscribers, > > I've been a ham for quite some time as a Technician class using > 2-meter.

So pulling it will cause it to stretch but when it breaks it does not return to its original length releasing a lot of energy. It will simply separate at the point of failure, as others noted. Even so, I am careful any time I'm applying a lot of pressure to anything.

When building my two K3 radios, I always first built a 10 Watt unit and got it working before adding the amplifier. One of the nice features of the K3 / K3S is the ability to add modules later. Just consider the DVK and 1 ppm TCXO for your initial purchase. You may not want to remove the front panel later. Additional filters are easy to add later. What ever you do Bob you will like the K3S. 73 Doug EI2CN -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bob McGraw K4TAX Sent: 13 February 2016 17:40 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3s pre-purchase question Based on your current operation and your present listing of equipment, I'd suggest the K3S-100.

The instructions in the K3S assembly manual are excellent and very gratifying once you have built it. Just take your time. I only dedicated 3 hours each day to make sure I did not make any mistakes. I would go simple to start with. Given your antennas, you really want the 100 watt option. K3S - 100w Kit, Digital Voice Recorder, Auto Tuner, Filters - 400 Hz for CW/ Digital, and 2.1 and standard 2.7 kHz for SSB. Unless you are really into contesting, forget the second Receiver for now. You can always add it later. That's all you need to get started. I do not do much 2 meter operation, so I have not added that option. Primarily I am on FM local repeaters. The same goes for the general coverage option/filter. Consider adding the P3 option in the future. Good luck and enjoy the radio.

I also have an LP-100A which is in series right next to the monitoring head of the P3 monitor. The KPA500 and the KAT500 both indicate an SWR of between 1 and 1.2 and the LP100A indicates an SWR of 1.05 into my 500watt 1.3GHz 50 ohm dummy load. However the P3 TX mon says SWR of 1.67. Now it is not a cabling issue as it does not matter which way round the monitor heads are (the LP100A head either before or after the P3 Mon head) the results are the same. My question is why the big difference - I had every expectation that the P3Mon would say something very close to that shown by the LP100A, the KAT500 and the KPA500. Any ideas as to what is going on. BTW my P3 firmware is uptodate.

CONTRATULATIONS!!! >>>I've built many Heath kits in the day, so the Elecraft kits are striking my interest. Excellent choice!! >>>I'm trying to configure a K3s kit and would sure like some help from you experienced hams.

Definitely do a full inventory/count prior to starting. >>>The up-front price is a lot for me so I'm trying to understand the necessities? With an upgrade path every 6 months or so. My opinion: Unless you're a hardcore contester the DSP does a WONDERFUL job of filtering. I chose to grade the stock 2.7khz to 2.8Khz and add the 400Hz filter. It's my view now (and the advice I was given prior to my purchase) that you won't go wrong just going with the stock 2.7Khz filter (comes with) and use the radio to determine if you want anything else. I've turned off the 400hz filter to test and found the DSP is much more powerful than anything I've seen or used. The 400hz filter helps when the band is crowded/loud/noisy. >>>First, would I be disappointed with starting out with the 10-watt version? I imagine I'll be doing more listening in the beginning. But if 100-watts is important up front I'll get it. 10watts is fine. Put a lot of cash into low loss feedline and good antennas. If you can do a yagi you'll be amazed what an antenna with gain will do. If you CAN afford it then 100w is the standard. Understand what I'm trying to say. If you have high loss coax run into a non-resonant antenna then 1000W won't be of any value because you can't HEAR. Focus on hearing, If you can hear them then all things being equal you can work them, especially on CW. If you plan to use SSB mostly then definitely do the 100w. >>>How about filter options? I'm guessing the standard filter will be ok to start out with? Already answered >>>I may add the 2-meter option since my current radio needs replacing. If I do is the K144XV Reference Lock Board necessary for 2-meter operation? My opinion is KISS, keep it simply simple. If you want 2m then decide what modes you want. Since you're upgrading to General I'm guessing you already have some 2m gear. My view is to keep 2m separate unless you plan to do more expensive things like moonbounce..etc.. For Sat work there are better options at this time. Just my opinion. >>>How about the KBPF3A General Coverage Receiver Filter? I'm not sure what this is for. I listen AM stations now and don't have that add on that I'm aware of. >>>My antenna is a Cobra UltraLite Junior: 80-10 Meters 73 feet, installed in my attic. I also have an Astron VS35m Power Supply, Heil PR-781 mic, MFJ-993B Auto Tuner. Get low loss feedline and ensure you have good station grounds. >>>Please recommend what options I should get with the K3s kit. Personally: Kit + 100w + ATU to start. Later add crystals if you think you need them, if you catch the contesting bug the DVR is nice, I purchased it but haven't even used it to date. Remember if you can't hear it then you can't work it anyway. TX power has limited value.. better to be the elephant with big ears than an alligator...all mouth no ears... :) 73 ..

Which DATA sub-mode? If you are using the K3's internal decoder for RTTY, it's probably AFSK A. AFSK A is a *lower sideband* mode while fldigi is brain dead and will only work with *upper sideband* signals for most modes. fldigi can be "faked" into working with LSB on AFSK by clicking the "Rv" (reverse) button but that may not work for other modes. 73, ...

I've built and installed a KAF2? kit with several component changes to make it a little wider in bandwidth, so as to be more useful in general CW operating, scanning the bands?and contests rather than being focused on pulling the weakest signals out of noise and QRM.? It also retains the full bandwidth of the OP1 filter when off (but still switched in) and so does not impair wideband digital mode operation, as I believe the stock KAF2 will, to a degree.?

Since you will be a newcomer to HF, I would suggest you start with the basic 100 watt K3S until you discover what you really want and develop your HF operating style. With your antenna situation, I would suggest that you add the KAT3 internal antenna tuner. If your operation on 2 meters will be mostly FM, then stick with your current FM gear. If you want to operate FM and/or AM with the K3S, you will need the 13 kHz filter. Yes, order the K3S kit, it is no solder, but plenty of exercise with a screwdriver. The main advantage is that you will be familiar with the inside of the K3S and you will not hesitate to add whatever additional options you might want later. 73, Don W3FPR On 2/13/2016 12:28 PM, Tom Brohl wrote: > Hello Elecraft subscribers, > > I've been a ham for quite some time as a Technician class using > 2-meter.

I have read about and seen plans where someone has installed a solar panel charge controller inside a K2 and added an extra jack (or used an existing unused hole) to feed in the power from a solar panel. If your panel generates enough voltage to charge the battery but only has a 2.5 watt rating it is going to take a long time to charge a 7 amp hour battery. -- Cheers!

The important thing is to count the turns correctly. Each time the wire passes through the center of the core, that is one turn - in other words, a straight wire through the core is 1 turn, a full wrap around the core is 2 turns. The advantage of using the winding direction you had for L10 is that the finished toroid will rest on the board like its outline. Electrically, they can be wound either way. Do check the stripping and tinning of L9. The one lead that is in the photo looks like it may be poorly stripped and tinned. The indications I see are that there is some red in the solder and there is a sunken ring in the solder around the wire. One of the most common failures in kit building is PTTL - Poorly Tinned Toroid Leads. 73, Don W3FPR On 2/13/2016 1:54 PM, Mark Petrovic wrote: > Hi. > > I'm not sure how perfect the wound inductors need to be when > assembling the K1 filter board. > > Here's mine: > > https://drive.google.com/open?id=0B2mjyTRatLHGNXZwVFZXc0FISFU > > Do these look good enough?

Since cost is an important consideration for you (isn't for all of us?): KX3-K = $949.95 MH3 = $59.95 KXFL3 = $149.95 (optional) KXAT3 = $199.95 (optional) total = $1009.90 ($1359.80) to add 100w: KXPA-100-K $749.95 total = $1759.85 ($2109.75) vs K3s/10-K = $2099.95 MH2= $59.95 total = $2159.90 to add 100w: KPA3A = $599.95 total = $2759.85 difference = $1000 ($650.10) I have best of all worlds (my opinion) with both K3/10 + KX3-2M + KXPA-100. I have several options added but left them out of the basic comparison (above). Since you have a mic probably delete the MH3/MH2 in the comparison. If just starting out on HF the options are all something one can add to Elecraft equipment as you decide if they are needed/wanted. But if you know for-sure, now, then buy them with the radio. Its your money! If 2m-SSB?CW is not on your list better to buy a 2m-FM rig. I cannot comment on the K144XV but the REFlock is probably a good choice if running SSB (an especially digital modes). 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From kilo6te at yahoo.com Sat Feb 13 16:33:31 2016 From: kilo6te at yahoo.com (Wim Dewilder) Date: Sat, 13 Feb 2016 21:33:31 +0000 (UTC) Subject: [Elecraft] For Sale K3 / 100 References: <464426707.3061522.1455399211135.JavaMail.yahoo.ref@mail.yahoo.com> Message-ID: <464426707.3061522.1455399211135.JavaMail.yahoo@mail.yahoo.com> I posted my K3 / 100 for sale on QRZ https://forums.qrz.com/index.php?threads/elecraft-k3-100.511487/ Options installed and that come with the radio - Elecraft MH2 microphone - KAT3 Internal Tuner - KPA3 100 Watt internal PA - KXV3 RX Ant.

That's in the same category as the ten FM transmitter diplexer at Stonehenge Tower in Portland but not all of the stations are 100 KW ERP. In addition to those on the master antenna, there are several FM low power/translator/auxiliary transmitters as well as a few ham repeaters on different antennas on the same tower. Stonehenge Tower itself is a self-supporting three-legged monster, with the coax sewer pipes running up a center 4-foot diameter shaft. The site ground level is 303 m AMSL and the center of radiation of the antenna is 170 m above that. It is a work of art. Our SBE chapter gets up there for a weekend potluck meeting every other August (we go to a different nearby 1000-foot tower site in alternate years). We haven't tested how an Elecraft will operate in any of those fields although one of our members lives in the house adjoining the base of the tower, a former radio studio building. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon Vice Chair, SBE Chapt. 124 From ron at cobi.biz Sat Feb 13 21:46:57 2016 From: ron at cobi.biz (Ron D'Eau Claire) Date: Sat, 13 Feb 2016 18:46:57 -0800 Subject: [Elecraft] how much to stretch copper wire In-Reply-To: <56BFBF90.6090206@kanafi.org> References: <005c01d16529$9049df80$b0dd9e80$@erols.com> <56BD2BCE.60101@nycap.rr.com> <56BD7263.3060908@audiosystemsgroup.com> <56BFBF90.6090206@kanafi.org> Message-ID: <000901d166d1$f8d3e790$ea7bb6b0$@biz> Yep.

Those who don't will find them on the ground in the first good storm. Ask me how I know! A few years after I moved here, I put up several wires and was one weight short of having enough for all the antennas.

At the beginning, you want contacts to come easy. I do a fair amount of QRP, but I've been on HF for decades. At the beginning, when I fumbled around a lot (people would argue I fumble around now ;-)), it would have been nice to have a rig that made up for my fumbling. For this reason, I suggest that you get the 100 watt PA and the auto antenna tuner (it's very fast, efficient and easy to use) and nothing else. I agree with the earlier poster who said that, although the 400 or 500hz roofing filter is nice (I have the 500hz), the DSP does fine unless you're in a contest environment. Given your antenna system, you'll find that this setup will get you plenty of contacts with a relative degree of ease. I wouldn't bother with the general coverage receiver filter. Shortwave listening was a lot of fun when I was a kid but today, I find myself doing none of it. So I have never missed that filter. As for the 2 meter option, I don't have it in mine, since I have a fully capable FT-736R that I use for satellite work. However, I'd focus on making your K3s functional for HF before you decide to make it functional on VHF (I realize the K3s has 6 meter capability). Good luck and hope to see you on the air. 73 de Bernie, KF0QS, K3s/100 sn 10323 From kevin.stover at mediacombb.net Sun Feb 14 12:07:28 2016 From: kevin.stover at mediacombb.net (Kevin Stover) Date: Sun, 14 Feb 2016 11:07:28 -0600 Subject: [Elecraft] K3s pre-purchase question In-Reply-To: References: Message-ID: <56C0B450.1080804@mediacombb.net> In a previous post you received advice suggesting you download and read the assembly and operating manuals before buying the rig.

Message-ID: Tom; Lots of good suggestions to your original questions and I'll add a couple more. I built my K3 from a kit and it was an absolute joy to put together (much more than I expected). The instructions are all very clear and easy to follow. So, if you take the plunge into assembling your own: 1) Get a good anti-static mat with a wrist strap and always use it while building. I grounded my Radio Shack mat via the third pin on a wall outlet (and I made sure it was a good ground with a 3-prong circuit tester beforehand). 2) A big plastic fishing tackle box like those sold at Wal-Mart was invaluable for putting all the many different sized screws in separate cubbyholes. Also, get a little screw size chart like those sold in Home Depot or Ace. After a little use you'll be able to tell a 3/8th from a half-inch easily as well as differentiate the different head types, washer types and so on. 3) A quarter-inch nut driver and/or crescent wrench is practically essential as well as a set of tiny screwdrivers. Harbor Fright sells these for a couple of bucks. They also sell magnetic parts cups that come in handy when you get a set of tiny bits together ready to install, too. 4) Have a clear table or work surface ready in advance. Arrange good lighting and a big magnifying glass on standby---especially if you are an old guy like me! 5) Lastly, budget your time for building---don't rush or try to get it done quickly. I found the whole process of building my K-Line rather therapeutic, like painting, hiking or enjoying a good concert. I will always look back at the good time I had putting it together and then utilizing it to go out and snag some great DX out of the airwaves with great fondness. A lot of folks are selling their K3s now to fund a purchase of a K3S---but I would rather hang onto the first rig I ever built and make upgrades now and then instead (but I'm a sentimental old fart). I guarantee you will enjoy the building process and you'll save a little dosh that can be put towards a better antenna or improvement down the road. Btw, the general coverage bandpass filter you asked about lets you SWL the shortwave broadcast and MW broadcast bands with much greater signal strength---they're suppressed without it. As long as you have the 13kHz or 6kHz filter you'll be good to go for SWLing---but just either filter is sufficient for casual SWLing as I sometimes do. I do recommend adding the ATU and sub-receiver option if you can afford to do so (and want to chase DX). The sub-receiver is great for split operations and I can't imagine not having one---but that's just me. You can always add these and all the other goodies later on but it is more convenient to install some options like these early on as the sub receiver will need to be removed and reinstalled if adding more filters or some other options that fit underneath it. I've rambled more than I intended to but when I think back to the time when I was getting ready to spring for the K-Line I had lots of questions, too---and I'm glad I did my homework as it paid off well once the big boxes from Aptos arrived.

The K3 and K3S are quite easy to upgrade, so feel free to buy only what you need now. I too would go for the 100W amp and tuner, and buy no extra roofing filters. By all means, buy it as a kit, which saves you $250. The only reason not to do so is if you have some sort of physical handicap that makes it difficult for you to do relatively simple mechanical assembly. And, especially if you're tight on dollars, strongly consider a used K3. I own three, which I have upgraded with the new synth board and the new KXV3B (both come with the K3S), and I see no need to replace these radios with the newer model. 73, Jim K9YC On Sun,2/14/2016 9:07 AM, Kevin Stover wrote: > In a previous post you received advice suggesting you download and > read the assembly and operating manuals before buying the rig. > ABSOLUTELY DO THIS!

There are however, exceptions such as the 3905 century club which has a great bunch of very decent people on it and they very much welcome newcomers. It is a county hunter's net though and absolutely not a net to argue whatever topic is out there and then grandstand your position like so many 75M nets are. http://www.3905ccn.com/newsite/index.htm Worth a listen if you wish to work 75M and if you do, your K3 will be an excellent radio for you in all ways. 73, Gary KA1J From n1rj at roadrunner.com Sun Feb 14 15:42:59 2016 From: n1rj at roadrunner.com (Roger D Johnson) Date: Sun, 14 Feb 2016 15:42:59 -0500 Subject: [Elecraft] abject buffoonery In-Reply-To: <56C0BC0F.3020507@audiosystemsgroup.com> References: <6D360A6C6E24467FAFFF6660526EEF9C@Johnlabibm> <56C0BC0F.3020507@audiosystemsgroup.com> Message-ID: <56C0E6D3.9030708@roadrunner.com> For an international sewer; see 20 meters!

Since you will be a newcomer to HF, I would suggest you start with the basic 100 watt K3S until you discover what you really want and develop your HF operating style. With your antenna situation, I would suggest that you add the KAT3 internal antenna tuner. If your operation on 2 meters will be mostly FM, then stick with your current FM gear. If you want to operate FM and/or AM with the K3S, you will need the 13 kHz filter. Yes, order the K3S kit, it is no solder, but plenty of exercise with a screwdriver. The main advantage is that you will be familiar with the inside of the K3S and you will not hesitate to add whatever additional options you might want later. 73, Don W3FPR On 2/13/2016 12:28 PM, Tom Brohl wrote: > Hello Elecraft subscribers, > > I've been a ham for quite some time as a Technician class > using 2-meter.

Nets where I can find a wealth of information on nearly any topic - including ham radio. Knowledge with real-world experience, not just spouting theory and numbers as if knowledgeable. A place where contacts amount to much more than another little check in the LOTW or "you are 59 - please repeat your callsign slowly three or four times." A place on the bands where antenna building and conversation is always welcome. A place where equipment design/mods can be discussed, rather than just purchase price complaints. The home of some really fine armchair signals - on SSB and on AM. Elitists? Not so much!

There are still many fine operators here as there were in the US. Just don't be drawn into making a comment is the best advice. These types of folks enjoy what they do even though it disgusts the vast majority it's best to move your VFO. I have chatted with some amazing people over the years, too many to mention obviously, but if I may, I will single out ONE in particular. During a field day here in VK, I had a call from a ham I not only respected, but one who I had heard so much about and getting that call simply blew me away, I was so humbled that day, and that QSO, along with many more have made me realize what a truly great hobby we have.....enjoy the ride! Oh, the guy who called me?....why of course, it was WA6HHQ and after I literally picked myself up off the ground I had a great conversation with Eric. This list has some of the best minds in our hobby (you know who you are) always willing to help, active on the bands as well as here and for me, this is another reason our hobby is strong and growing in relevance. I hope I can work you on HF from VK some day, I sniff the ether daily for signals from the US, lived there for many years and consider it my second home. 73 Gary -----Original Message----- From: "Brendon Whateley" Sent: ?15/?02/?2016 7:07 AM Cc: "Elecraft Reflector Reflector" Subject: Re: [Elecraft] abject buffoonery Guys, as a relatively new HAM, although I do have my extra, I'd like to say that I find this kind of negative discussion is really off putting. - Brendon KK6AYI On Sun, Feb 14, 2016 at 12:42 PM, Roger D Johnson wrote: > For an international sewer; see 20 meters! > > On 2/14/2016 12:40 PM, Jim Brown wrote: > >> On Sun,2/14/2016 9:17 AM, John wrote: >> >>> "A third word of advice...until you have some HF miles under your belt, >>> stay away from the abject buffoonery known as 75 meters." >>> Is there a problem with one of our bands? >>> >> >> There is in much of the United States.

I have cordial email and sometimes phone exchanges with customers, and they are always gentlemanly. I have been repairing gear for Elecraft owners of those now legacy transceivers since 2004 and have never had a problem with payment for my services and communications with those owners has always been quite pleasant. Perhaps Elecraft owners are an 'elite' group, but for my part I find that most hams are quite the gentlemen. There are exceptions, but I believe they are in the minority. When those exceptions do appear, they seem to 'take the stage' - I count the "UP cops" and some of the conversations on 75 meter SSB or AM as some of those exceptions.

I spent considerable time trying to find the best way to do RTTY with RUMlogNG. RUMlogNG can use the RTTY support built in to the K3 via the RS-232 link. It works well for transmit, although given the number of times I had to repeat my call, I wonder if there was a slight frequency difference between the audio coming in to the computer thru the sound card from the radio and the transmit frequency. It seemed like there was enough of a difference that the running OP had to fine tune my signal to decode it. I did center the CWT tuning indicator on the K3, and when I turned on Dual PB, the computer was getting the signal on the right frequency. My big problem was on receive. I never got the radio to cleanly decode. It missed almost all the call signs, regardless of strength of the signal. I tried using fldigi, which did work, and cocoaModem which seemed to decode better than fldigi. I ended up using cocoaModem and logging manually. (Next time I'll probably steal the VGA screen from the P3 and use it as a second screen on the computer so I can see all of both programs windows.) The question is, what am I doing wrong with getting decoding to work on the K3? 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | Truth and love must prevail | Periwinkle (408)356-8506 | over lies and hate. | 16345 Englewood Ave www.pwpconsult.com | - Vaclav Havel | Los Gatos, CA 95032 From dave at nk7z.net Sun Feb 14 19:57:15 2016 From: dave at nk7z.net (Dave Cole) Date: Sun, 14 Feb 2016 16:57:15 -0800 Subject: [Elecraft] CQ WPX RTTY Contest In-Reply-To: References: Message-ID: <1455497835.7878.54.camel@nk7z.net> Hi, Did you have Data Submode "AFSK A" turned on? -- 73's, and thanks, Dave For software/hardware reviews see: http://www.nk7z.net For MixW support see: https://groups.yahoo.com/neo/groups/mixw/info For SSTV help see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Sun, 2016-02-14 at 16:51 -0800, Bill Frantz wrote: > I just finished casual operation in the contest.

Hams are no better or worse than any other slice of humanity, I suspect. We just get to radiate it to a bigger audience than most. I don?t operate on any ?phone" band (SSB, FM or AM), but I know from personal experience that similar nonsense occurs elsewhere including where I do operate - CW on 80 through 10. The intentional QRM, DQRM, especially on 20 and 15, isn?t just buffoonery - it?s malicious and it?s illegal. So far as I know there is no band plan that reserves a segment for utopia, not even the bottom 25 Khz where Extras reside. But, to access the pretext of making this subject not utterly OT, isn?t it nice to have an Elecraft rig to navigate through the reality?

I?ve used this method of RTTY operation on the K3 for casual operation, and my biggest difficulty was tuning to the exact correct frequency on the K3 to get solid decoding of the received signal. I?m used to working with MMTTY on the computer, with the simulated crossed ellipses on the screen to tune in the signal; without that aid, even though I know what the signal is supposed to sound like, I have to play with the tuning to get it exactly correct for decoding (I can usually get it to work OK to make the contact, though). With that in mind, maybe your problem with the other station copying you is the same problem you?re having with decoding: even with the CWT indicator, you?re not getting exactly on the correct frequency, Are you using FINE tuning on the K3? That seems to be almost a necessity to make the fine adjustments needed to tune the RTTY signal correctly for receiving and decoding. Hope this helps.

I used my KX3 with the PX3 and a USB keyboard for S&P calling and reply including the serial number using function keys. I used logging to keep track of the few contacts I made on a separate computer. I operated on 80m and used FSK D on the KX3 to display on the PX3. I found having the bandwidth as narrow as possible plus just a tad wider. I think something about 250 Hz wide worked well and I had very little problem copying call signs or serial numbers. One time I did have to wait for his next contact to conform the number. I DID have a problem with some stations needing a repeat of my serial number as I was running 5 watts (using an 80m horizontal loop - 15' above ground). With the PX3 keyboard messaging and \c for serial number I sent the \c twice but if I needed to re-send the \c string, the number would increment and it is NOT easy to decrement the number. I just sent the number "by hand". It would be nice yo have \d to decrement the number before sending again. With the PX3, tuning was easy and accurate. With CWT alone, tuning needs to be "somewhat" even on either side of CWT and then watch how it decoded. Without the PX3, I would have used fldigi, a USB sound card, and the KX3 using DATA A (because I can use all the modes fldigi has)... 73, steve WB3LGC On 14-Feb-16 8:30 PM, John E Bastin wrote: > > On Feb 14, 2016, at 19:51, Bill Frantz wrote: >> >> My big problem was on receive.

Portable will be an issue - unless you have a very small screen for logging (I personally use a school notebook - and just retype when I get home). What ever your choice - Raspberry/Phablet/Notebook/Laptop/Road-Warrior battery life will be your governing issue. It seems pointless to me to drag a 14V power source just to power a laptop (school notebook requires even less wattage the the KX3) - use those stored Watts to radiate a signal. The KX3 - will do digital modes very well - so even /P you do not need a computer (I would not suggest you try and do contests without one mind you) - you just need to be able to send Morse (it is amazing to hear the PSK/RTTY being generated). You could do some large Macro?s (using the KX3 Utility) and not bother with most of the CW - but you will always need to say the other parties call-sign etc. And soon you will want to join the fun of CW operating (which the KX3 does amazingly well also) Whatever you choose the KX3 - is a great rig?. and so similar to the K3-S it makes switching between them almost seamless.

My set up though is a bit different than your's I think. I use the K3 set to FSK D and cocoaModem as a back up. I tune the signals using my P3 set to about 15 Khz span and tune to the Right (space) signal. The only repeats I needed to give didn't surprise me since I am running only 100W to a wire. I found that cocoaModem was slightly better at decoding but most of my decodeing and therefore grabbing call signs, etc. was from the RUMlogNG display with cocoaModem used mostly as an occasional backup. Interestingly enough, I found a few situations, especially on weak and/or fluttery signals, where the K3 did a much better job of decoding than cocoaModem. I also spent some time running FLDIGI on the side but found it was not nearly as good as cocoaModem or the K3 in decoding.

That is correct although with the K3/K3S since the Elecraft mic RFI change it should not matter (both pin 7 and pin 8 are connected to the "ground" foil on the front panel circuit board). Early K3 front panels included an RF choke in the mic *and* PTT returns which made the "pin 1 problem" much worse. With the RF choke removed (bypassed) the issue is significantly reduced but there may still be a problem if the overall station installation has any "RF on the coax." 73, ...

Without diving into the details, I helped W6OAT chase down RFI issues in his station. He had a MicroHam box with an "interface" to the radio that was a jumble of wires. Virtually NO attention had been paid to the fundamental concept of a transmission line in the interface between it and the radio. While that is acceptable at baseband (audio), it is monumentally foolish when RF is present (i.e. an antenna on the roof). Current flows in loops, whether at DC or at RF, and the loops form both antennas and magnetic loops whose coupling is proportional to the loop area. In the near field, magnetic coupling dominates, so the loop area can be a VERY big deal. EVERY signal path between devices must be treated as a transmission line of RFI is a potential issue. That means EVERY signal path should be a twisted pair or a coaxial pair, so that the path forms a transmission line. Any interface that does not do this is an invitation to RFI if the antenna is close enough, or if the power is high enough, or both. This is NOT an indictment of Microham -- at a CQP expedition a few years ago, a team member showed up with an interface betweeen is radio and his amp to key the amp that was an RCA to RCA cable with a single wire, no shield. Chassis to chassis was depended on for the return. That works fine at DC to key the amp, but the resulting current loop area gives that circuit VERY STRONG coupling to an RF field, both as a magnetic circuit and as an antenna. Noted RFI guru Henry Ott talks about understanding where ALL the current flows, which is revealed by "the hidden schematic lurking behind the ground symbol" that causes most issues with RFI and crosstalk. 73, Jim K9YC From gm3sek at ifwtech.co.uk Mon Feb 15 06:42:32 2016 From: gm3sek at ifwtech.co.uk (Ian White) Date: Mon, 15 Feb 2016 11:42:32 -0000 Subject: [Elecraft] K3 KIO3B - FSK - stereo In-Reply-To: <56BE546B.9030905@storm.ca> References: <56BE546B.9030905@storm.ca> Message-ID: <005301d167e5$fab96200$f02c2600$@co.uk> VE3KI wrote: > >Also, make sure that the USB Audio Codec is not selected as the Default >Device or the Default Communications Device - these should both be set >to the motherboard sound card in your PC.

The RasberryPI - will work to the KX3. I have used mine on and off for some development stuff. Portable will be an issue - unless you have a very small screen for logging (I personally use a school notebook - and just retype when I get home). What ever your choice - Raspberry/Phablet/Notebook/Laptop/Road-Warrior battery life will be your governing issue. It seems pointless to me to drag a 14V power source just to power a laptop (school notebook requires even less wattage the the KX3) - use those stored Watts to radiate a signal. The KX3 - will do digital modes very well - so even /P you do not need a computer (I would not suggest you try and do contests without one mind you) - you just need to be able to send Morse (it is amazing to hear the PSK/RTTY being generated). You could do some large Macro?s (using the KX3 Utility) and not bother with most of the CW - but you will always need to say the other parties call-sign etc. And soon you will want to join the fun of CW operating (which the KX3 does amazingly well also) Whatever you choose the KX3 - is a great rig?. and so similar to the K3-S it makes switching between them almost seamless.

If you failed to do that, the K1 would show a low power even though it was actually developing full power output. Make sure the ATU menu is set to CAL P. If you are measuring power output with an external wattmeter, then check the soldering of the KAT1 toroid leads. You should not see any enamel on the solder side of the board and you should see a bit of tinned lead above the board. 73, Don W3FPR On 2/13/2016 11:11 PM, Michael via Elecraft wrote: > I just built a new K1 and had some problems with the output power.

Interestingly enough, I found a few situations, especially on weak and/or fluttery signals, where the K3 did a much better job of decoding than cocoaModem. I also spent some time running FLDIGI on the side but found it was not nearly as good as cocoaModem or the K3 in decoding.

There I can participate in relatively nonsense free and enjoyable rag chews with others. About the only time we get substantial craziness on that mode is when there is some sort of DXpedition going on. For the most part, I don't think that, for the most part, these clowns (I actually have a much stronger, more profane term for them!) can even copy CW. So, it's not much "fun" for them to jam conversations they can't even understand. I also think that alcohol has a great deal to do with what you hear on 75 meters. Sometimes it is completely obvious! I don't know about the rest of you, but I would be willing to pay a significant additional fee, and every year if necessary, if FCC could then do serious enforcement on the bands. I know right now they don't have any real staff to do it. You wouldn't even need a particularly high percentage of successful enforcement situations to generate substantially beneficial results. Just having a real threat that such actions might be successfully captured could be enough to put "the fear of God" into a significant number of perpetrators. Right now, there is little, if any, risk of being caught. So, it is like having speed limits, but no enforcement whatsoever! A lot of people say "just ignore" the incidents. I tend to agree with that, since confrontation only excites the perpetrator--particularly if alcohol is involved!!!! You can't argue or reason with a drunk! I do think recordings could be helpful, and if you have the capability, a little "DFing" might add some useful info if there was any place such info could be collected for further analysis. I think every ham radio club in the country should take this issue seriously. Not only should members "pledge" to avoid such conduct, they should also agree to be actively involved in identifying it. It's hard to believe that a number of these perpetrators aren't close enough to someone else that they couldn't be better identified. We need to take some responsibility ourselves for trying to reduce such infractions. That doesn't mean direct confrontation, but serious information could be useful to authorities. Just my thoughts.

In addition to Windows sounds, you wouldn't want sound clips from your Internet browser playing through the radio codec, to pick an example. Another reason might be that if the K3S or K3+KIO3B is turned off or disconnected from the computer, the device would disappear and Windows would change the default to some other (possibly unpredictable) device. There may be yet another reason: I believe that in recent versions of Windows, when a device is selected as the default device, Windows routinely disables other inputs on that sound card or codec. If, for example, the microphone input were selected as the default device, I believe that the line input on that same card would be disabled. I don't know whether the KIO3B codec has multiple inputs, so I don't know whether this actually applies to it. 73, Rich VE3KI W3FPR wrote: > Ian, > > The operating system plays its sounds through the default soundcard. > You really don't want to transmit those sounds on the air. > > 73, > Don W3FPR > > On 2/15/2016 6:42 AM, Ian White wrote: >> VE3KI wrote: >>> Also, make sure that the USB Audio Codec is not selected as the Default >>> Device or the Default Communications Device - these should both be set >>> to the motherboard sound card in your PC. >> Please could you explain the reasons for that? >> >> From gm3sek at ifwtech.co.uk Mon Feb 15 11:09:19 2016 From: gm3sek at ifwtech.co.uk (Ian White) Date: Mon, 15 Feb 2016 16:09:19 -0000 Subject: [Elecraft] K3 KIO3B - FSK - stereo In-Reply-To: <56C1E3E0.4060707@storm.ca> References: <56C1E3E0.4060707@storm.ca> Message-ID: <009b01d1680b$3f491c60$bddb5520$@co.uk> Many thanks to Don and to Rich.

Your situation is only exceeded in nastiness by being next door to a 50 kW AM station and maybe not then. Your induced common mode RF voltages on conductors can be double and triple the desired signal voltages on the cables and ridiculously more than microphone voltages. One CAN get lucky and get by, but if one does it's only by dumb blind luck and any change to cable routing or position and count of station equipment can disable or polute electronic functions. If you succumb to the temptation to attribute the changes to the last thing changed or moved, you will be sent down the rabbit hole to join company with Alice and the Mad Hatter where nothing makes sense any more. This can include complaints to manufacturers straight from Wonderland requiring apologies afterward. Been there, done that. Know whereof I speak. It is quite probable that replacing the box changed cable specifics. Any connection that is not a tenth of an ohm or less needs to be replaced or repaired. I have no idea where you got 2 ohms as a satisfactory connection resistance. Maybe the USB signal itself will tolerate that under otherwise non-stressed circumstances but it's far away out of bounds for RFI proofing. In your case, QRO on the roof, you need to take maximum anti-RF measures on **ALL** conductors in the shack. Otherwise just changing orientation of cables may remove or incite RFI, or worse makes RFI intermittent leading to suspicions of poltergeist. I have finally gotten to the point where all retail audio cables need to be replaced with soldered coax or shielded pairs with WOVEN shields. ESPECIALLY audio cables terminated in RCA plugs which typically have the cheapest shields known to man. No retail manufacturer is testing them for RFI susceptibility in rooftop QRO conditions. There is a good selection of shielded pair and coax cable with Teflon dielectric/insulation and woven shields easily soldered to *quality* RCA plugs or other connectors without melting the wire. I know that QRO on the roof is all that's available for many folks. Just understand that's the very stiffest possible demand on all RFI proofing issues. No cheapies, no short cuts, no omissions allowed in the protocol. 73, Guy K2AV On Monday, February 15, 2016, > wrote: > Dear all, > > just an update..the Microham Microkeyer II has definitely a problem with > RF! > I replaced the Microkeyer with a homebrew USB and soundcard interface > (Built in 2008) and made new cable distribution box..And the problems are > gone. > > I have S-NO 280 on the microkeyer..hope the newer ones are better.

I would suggest you turn the SUB on (not Diversity) by tapping the SUB button (HOLD will get you into Diversity). With the SUB on, tune to your receive frequency with the VFO A knob. Then tap A > B twice to transfer the frequency, mode, etc to VFO B Then tune with the VFO B knob to your proposed transmit frequency. Now turn on SPLIT. Note the arrow in the display next to the TX label to the right side now points to VFO B. That arrow points to the frequency where you will transmit. You will hear the main receiver in your left ear, and the right ear will hear what is on your transmit frequency. If you want to use Diversity, the K3 will behave more like a single receiver, but if using 2 antennas (one on the main and the other on the sub), you may be able to hear better through QSB. In diversity, both the main and the sub are controlled by the VFO A knob. If you are in diversity and want to go split, tap the A>B button twice and then go to SPLIT. Move VFO B to your desired transmit frequency. You will not be able to hear on your transmit frequency unless you hold the REV button - while holding that button you will hear the TX frequency (but not your RX frequency). I hope that helps. 73, Don W3FPR On 2/15/2016 1:17 PM, Jeff wrote: > Can someone please help me understand if I am doing this correctly?

He does mention the flashing RIT and XIT annunciators. It might just be the way I use a quick reference. Usually, I know the menu items I use for CW so I rarely have to look something up that I want to do. Instead, I use a QR when I've done something inadvertently and get unknown annunciators or error code. So if I see the C flashing, I have no idea what it could be. I was looking for something that would tell me it means I'm in Test mode, not something that tells me how to select Test mode. hi. Anyway, thanks for the link.

The P3/SVGA was losing characters making the decode unreadable, as was RUMlogNG. If I quit RUMlogNG, the P3/SVGA stopped dropping characters and seemed to be showing the same decode as the K3.

I suspect that the K3s is like the K3. The setting for semi-break-in is to put the K3 into CW mode and then repeatedly press & hold the QSK switch until you see the word SEMI in the display. The connector for key out to operate the linear is an RCA female labeled key out, so the standard RCA male-to-male cable works fine between the rig and the amp. The paddle and key each require a standard, old-fashioned, large, phone plug. If you put the rig into semi-break-in mode on a given band, then go to SSB, you can turn up the CW speed and use the keyer to generate dots while the K3 is in SSB mode, as you use your output meter to tune up into your dummy load without having to operate with a steady carrier. This is the cheap ham's "pecker." I have been quite pleased with the operation of the AL-82 and the K3. 73, Jan, KX2A > I am getting my K3S soon.

Februar 2016 18:15 An: Horst Bernhard, MZ-LR; Elecraft Reflector Betreff: [Elecraft] Microham Microkeyer II, RFI in mike with my K3 Hi Bernie, If you are running QRO over your roof, your RFI proofing needs to be perfect. Your situation is only exceeded in nastiness by being next door to a 50 kW AM station and maybe not then. Your induced common mode RF voltages on conductors can be double and triple the desired signal voltages on the cables and ridiculously more than microphone voltages. One CAN get lucky and get by, but if one does it's only by dumb blind luck and any change to cable routing or position and count of station equipment can disable or polute electronic functions. If you succumb to the temptation to attribute the changes to the last thing changed or moved, you will be sent down the rabbit hole to join company with Alice and the Mad Hatter where nothing makes sense any more. This can include complaints to manufacturers straight from Wonderland requiring apologies afterward. Been there, done that. Know whereof I speak. It is quite probable that replacing the box changed cable specifics. Any connection that is not a tenth of an ohm or less needs to be replaced or repaired. I have no idea where you got 2 ohms as a satisfactory connection resistance. Maybe the USB signal itself will tolerate that under otherwise non-stressed circumstances but it's far away out of bounds for RFI proofing. In your case, QRO on the roof, you need to take maximum anti-RF measures on **ALL** conductors in the shack. Otherwise just changing orientation of cables may remove or incite RFI, or worse makes RFI intermittent leading to suspicions of poltergeist. I have finally gotten to the point where all retail audio cables need to be replaced with soldered coax or shielded pairs with WOVEN shields. ESPECIALLY audio cables terminated in RCA plugs which typically have the cheapest shields known to man. No retail manufacturer is testing them for RFI susceptibility in rooftop QRO conditions. There is a good selection of shielded pair and coax cable with Teflon dielectric/insulation and woven shields easily soldered to *quality* RCA plugs or other connectors without melting the wire. I know that QRO on the roof is all that's available for many folks. Just understand that's the very stiffest possible demand on all RFI proofing issues. No cheapies, no short cuts, no omissions allowed in the protocol. 73, Guy K2AV On Monday, February 15, 2016, > wrote: Dear all, just an update..the Microham Microkeyer II has definitely a problem with RF!

That is correct although with the K3/K3S since the Elecraft mic RFI change it should not matter (both pin 7 and pin 8 are connected to the "ground" foil on the front panel circuit board). Early K3 front panels included an RF choke in the mic *and* PTT returns which made the "pin 1 problem" much worse.

The antenna on the roof transmitting high power is doing its job, putting a lot of RF in the shack. If it didn't (based on proxmiity), it would be a lousy antenna. The problem is that the interface (wiring plus electronics plus termination) does not reject RF because it fails to conform to fundamental principles that reject RF. That is, every cable must be a transmission line, every shield must be terminated at the shielding enclosure of the equipment at both ends, and every equipment chassis must have a short, fat, bond to every other equipment chassis. Yes, the signal is audio, but the interference is RF, and it takes proper transmission line techniques to reject that RF. I have VERY limited experience with MicroHam, but the jumble of wires that I encountered with the MicroHam unit at W6OAT violated all principles of good engineering practice for operation in a high RF environment. It was nothing more than a multipin connector with a lot of wires soldered to that connector. Indeed, it would darn near impossible to do it right without starting from scratch withunit a properly made cable from the MicroHam unit to the radio, with each signal path having its own coaxial cable. I have no idea if that describes ALL MicroHam units, but it does describe Rusty's. And don't ask the model number -- I was so disgusted by what I saw that I just rolled my eyes. 73, Jim K9YC On Mon,2/15/2016 10:43 PM, Bernhard.Horst at bmw.de wrote: > Hi Guy, > > Fully agree with your statement, but as stated I have chokes in all Coax, rotor and control cables. > I am using double shielded USB cables, extra grounding for each device?no idea what else could be don. > Regarding the 2 Ohm, there is a recommendation by Microham to check that the USB / Molex connector resistance should not exceed 5 Ohm otherwise your PC has a USB/Chassis grounding problem. > > I had RFI in the Microham already with 300Wtts?now I can run 1200Watts without any problems with is over the legal limit over here anyway! > > Several HAMs observed problems with the Microham and in combination with K3/other rigs. > The cheap homebrew USB/Soundcard interface works now, that?s all what counts. > > 73 > Bernie > DL5RDP > > Von: guyk2av at gmail.com [mailto:guyk2av at gmail.com] Im Auftrag von Guy Olinger K2AV > Gesendet: Montag, 15.

The band changes all work fine. I'm certainly not a technical guy, but it seems to me the transfer from radio to amp to key the amp is working fine. There is something after key down that is shorting or somehow malfunctioning that shuts the amp down. I can turn the power on the K3 down to 10 watts and tap the paddle and the amp works, but put two dits in a row and it shuts down. I've inspected the inside for transformer damage and there is nothing visible. The one lead that Elecraft gave me was that the screws for the tilt bar were installed backwards, leading to the possibility of a short with the transformer. I had to remove the transformer to reverse those screws, (they sent me the procedure), but that wasn't the problem either. I didn't use a configuration that would require the interrupter. Thanks for your comments and thoughts. 73, Mike AD5A -----Original Message----- From: Mark E.

This eliminates the antenna. Yes, I know the SWR is 1:1, but it eliminates it as a possible problem and you are not putting a signal on the air causing QRM. Go into the KPA500 menu and make sure RADIO is set to K3. Are you using the key out of the K3 to the key in (PA KEY) on the amp for keying the amp or are you keying the amp through the cable connected to the K3 accessory socket? If you are using key out to key in, did you put the keying interrupter for pin 11 on the K3 accessory jack? Try the basic cabling setup as described in the manual. Just connect RF IN from the K3, RF OUT to the dummy load, KEY OUT on the K3 to PA KEY on the KPA500. Leave the cable from the K3 accessory socket to the KPA500 AUX socket disconnected. See if it operates in this configuration. Let us know the results.

It arrived from the seller, well packed and complete with cables, manuals, etc. I turned the amp on, interfaced it with my K3, keyed the radio and the KPA500 immediately shut-off. No fault light or error code, nothing. It shuts down just as if I had pressed the power button, the fan runs, etc... The antenna is resonant 1:1, I've lowered input power to 10 watts, swapped coax, hooked it up to another K3, used RCA to RCA cable, the Elecraft cable, etc.. When down to 10 watts input, I can tap the paddle like a straight key lightly and the amp works, but put two dits together and it shuts down. Has anyone had an experienced anything like this. I keep thinking this has to be something simple.

The connector for KEYOUT is an RCA connector. Both the Key and Paddle jacks are 1/4 inch phone jacks. You would benefit by downloading the K3S manual to see the connectors on the rear panel and also look at the list of CONFIG Menu items to get an idea of how the K3S can be customized for your use. Normally the menu defaults are usable, but better operation suited to your operating preferences can be achieved by varying those parameters. One thing I insist on changing for my personal operation are the AGC Threshold and Slope parameters. If you want to see a discussion on what happens when you change those parameters, look at the "Noisy K3" article on my website www.w3fpr.com. 73, Don W3FPR On 2/15/2016 7:05 PM, Scott James via Elecraft wrote: > I am getting my K3S soon.

One piece of info I can give - there is no scenario in firmware where a fault will power off the amplifier. All faults will leave the amplifier in the STBY state with the amplifier on. With some you won?t be able to transmit, but the amp will still be powered. Make sure all connections are right, that no cables are offset or otherwise misconnected. What version of firmware is in the KPA500? If not V1.38 or later, you should upgrade. Otherwise talk to the CS folks in Watsonville. This is a strange situation. It would be interesting to see the fault table for the amp (you might send me a fault table for analysis). With the amplifier shutting down so quickly I doubt if anything is being saved, though.

One piece of info I can give - there is no scenario in firmware where a fault will power off the amplifier. All faults will leave the amplifier in the STBY state with the amplifier on.

The frequency on the waterfall of the Px3 and the skimmer are correct. Within skimmer I have narrowed it down to 30 Hz difference between the CW Pitch and Audio IF And this is the known differece between Kx3 and official frequency. I need a better source for calibrating. But later I switched from 20m to 40m and still no offset between Kx3, Px3 and Skimmer. But after 30 minutes I got from RBN the warning, that I am -1.8 kHz off.

One of the reasons people get a KPA500 is because they can't get 240 to the shack and the KPA will run on 120V. That makes it non-idiotic to inquire upon the 120V supply. I heard of a problem something like this, not a KPA500, that turned out to be a defective wall outlet. I would imagine that the KPA500 is unforgiving of a precipitous drop in AC voltage. In the case I cite, all kinds of wierdness in the shack went away when the wall outlet was replaced. The defective wall outlet had internal blades that were badly pitted. It was also very old by any means of estimate. I also heard of a power cord that was not crimped correctly inside the molded plug, discovered upon dissection style autopsy afterwards. Other issues would be aluminum wiring that had not been tightened up, a single bad socket in a power strip, etc. Also have heard of a wall socket connection where one of the screws on the outlet had never been tightened. A KPA500 is a hard pull on a 120V socket. It would not matter to the AC power that you were just hitting 10 watts, because you turn on the idling current as soon as any RF is sensed. Do not assume that the 120V supply is A-OK. Verify everything on that 120V circuit, up to and including the breaker in the breaker box. Breakers go bad too. In any event the very best of luck chasing this aggravating problem. Please let us all know what finally turns out to be the actual problem and what you did to fix it. 73, Guy K2AV On Tue, Feb 16, 2016 at 11:48 AM, Cliff Frescura wrote: > Can you measure the 110V line voltage on key down?

Turning the main tuning knob did not change the frequency. I microsofted it (turned it off and rebooted) and it was restored to proper operation that time. Now, it is frozen once more and that has not fixed the problem. The only thing I could find in the documentation dealt with locking the VFO, and unlocking. I have verified that it is "nor."

Or a long run of relatively small wire to the outlet from the panel. Or a bad splice at another outlet between your outlet and the breaker panel. Or perhaps you're not plugged directly into the wall, but into some other device or multi-outlet box. A good way to check this is to hang a voltmeter across another outlet wired directly in parallel with the power amp (most wall outlets are duplexes, two outlets in a single enclosure) and watch the AC voltage as you key the amp. Start with fairly low power (100-200W) and gradually increase it until the amp shuts down. As I recall, the KPA500 pulls about 10A at 120V for full power. There's a very useful device to measure voltage, current, power, VA, power factor, and even kWh. It's called Kill A Watt. You plug it into the outlet, then plug the device you want to test into it. There are several version of it. Here's one, which is what I have. http://www.p3international.com/products/p4400.html 73, Jim K9YC From joe at k2uf.com Tue Feb 16 14:16:12 2016 From: joe at k2uf.com (Joe K2UF) Date: Tue, 16 Feb 2016 14:16:12 -0500 Subject: [Elecraft] 10.118.288 dead carrier In-Reply-To: <00e301d168eb$ca3be060$5eb3a120$@gmail.com> Message-ID: Peaks here in upstate NY at about 210 deg. 73 Joe K2UF -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Mike Flowers Sent: Tuesday, February 16, 2016 1:57 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] 10.118.288 dead carrier Yep - I hear it too.

In the "good old days" the FCC's HF DF net would on request locate it as a routine matter and the field engineers/agents would follow up. No longer - sadly. Unless the problem involves Homeland Security, interference to public safety or other governmental communications, or criminal activity they don't do that any more, relying on us amateurs to solve our own problems. Of course, once we locate it, we have no authority to either access the premises or order the station off the air.

It doesn't appear to be RUMlogNG because it also occurs with the K3 utility. (Note: I found thi problem before communicating with Tom DL2RUM.) Here's my message to support describing the problem: When running the K3 utility (Mac version, but the problem might also occur with Windows and Linux), with the terminal window open, and having the P3/SVGA data display turned on, both the P3/SVGA and the terminal window lose characters during RTTY decode. The correct characters appear on the K3 display. Turning P3/SVGA data display off clears up the characters in the terminal window, and switching to one of the other windows in the K3 utility clears up the problem with the P3/SVGA. Simular problems occur using RUMlogNG's contest mode for RTTY. Given the easy workaround, this problem isn't super high priority, but if it will be with us for a while, people should learn about the workaround. 73 Bill AE6JV ------------------------------------------------------------------------- Bill Frantz | The first thing you need when | Periwinkle (408)356-8506 | using a perimeter defense is a | 16345 Englewood Ave www.pwpconsult.com | perimeter. | Los Gatos, CA 95032 From bparris23 at nc.rr.com Tue Feb 16 16:43:31 2016 From: bparris23 at nc.rr.com (Bill Parris) Date: Tue, 16 Feb 2016 16:43:31 -0500 Subject: [Elecraft] 10.118.288 dead carrier In-Reply-To: <001a01d168ef$1ab3abb0$501b0310$@cox.net> References: <72CDB7BF-CA87-4F83-B280-67F9078A96CF@optonline.net> <00e301d168eb$ca3be060$5eb3a120$@gmail.com> <001a01d168ef$1ab3abb0$501b0310$@cox.net> Message-ID: <9577D9D009154F08970F3FF49186B999@Billpc> it is S9+ here in Pinehurst, NC .... on all 5 antennas, none of which are cut for 30 m.

(The P3 with P3SVGA gets this data over the same serial path the external program does and the K3 flushes out the buffer after each read.) This is a one application at a time interface. Running a second app simultaneously will cause the loss of text you are experiencing. 73, Eric /elecraft.com/ On 2/16/2016 12:46 PM, Bill Frantz wrote: > Thanks to some off list advice, I think I have tracked this problem down.

If so, both the encoder board and the area of the Control Board behind the encoder board must be flush trimmed - and I mean really flush trimmed. Contact between the encoder board and the control board will cause problems like you describe as well as other "funny happenings". You can move the lockwashers on the Front Panel board for the standoffs between the front panel and control board from under the screwhead to the other side of the board (under the standoff) to provide a little more clearance. If you have the older encoder (without the PC Board), then check the soldering of the encoder pins and the wires to the Front Panel board. Also reflow the soldering on all the connectors that carry the ENC A and ENC B signals - there are connectors on the Front Panel, the RF board (2 connectors) and the Control Board. If all else fails, order a new encoder. It will be the encoder with the circuit board, so the cautions in the first paragraph apply, and you will have to ream the front panel encoder shaft hole slightly to pass the threads of the new encoder. The new encoder kit comes with a new knob - the old one will not fit the shaft. 73, Don W3FPR On 2/16/2016 1:57 PM, Jim Allen wrote: > I had this happen the other day.

The idea being to get the power reqs, size, and weight down for portable use. I've still not figured out RTTY in FLDigi but have chalked that up to not knowing FLDigi well enough yet. The K3S is 100% on RTTY and is sending audio over.. One other potential thing to work out is apparently when I run two sessions of FLDigi the audio device is only available to the first instance. I'll likely need to either figure out how to get it to share or setup a software mixer to connect to.. not sure yet. Eventually I want to add the SUB Rx and monitor two bands.

I know this is an often cited problem, but in many cases it is real. Given that it happens only infrequently, the source may be difficult to find. For instance, do you have an antenna swaying in the wind that can have a bad connection somewhere in the system that rears its ugly face and spits RF into the shack only when the wind blows in the right direction. It may be beneficial to create a log of conditions just before the problem occurs. What band, what power level, which antenna. In time, you may find a pattern. I can assure you that it is not a firmware problem or a general K3 hardware problem - if it were, yours would not be the only complaint about that behavior we have seen reported. That of course does not suggest that your particular K3 does not have a problem, only to suggest that it is not a problem that has been previously reported on the reflector. That means there is likely something happening that is either RF-in-the-shack, or something special about your shack interconnections to the K3. For instance, are you using computer keying in addition to the key or paddles? Something like that may be a contributing factor. Sorry, but no real answers, but a few things for you to consider as possible problem areas. 73, Don W3FPR On 2/16/2016 7:53 PM, Steve via Elecraft wrote: > I suppose I should look for this in the database, but I'm not really sure > what to call it.

Amplifier relays, bandpass filter relays, antenna selector relays are all suspects. It also could be a poorly soldered contact in the antenna, or an oxidized PL-259 center pin.

With the taps set so the key-up HV is near max (85V), the HV drops to close to the minimum voltage (60V) at 500 watts on some bands. That's all due to the 120V feed droop. There's no benefit from having the tap set for a mid-range voltage if the HV droops below 60V on key down. Below 60V the amp won't make full output on some bands and IMD is compromised. A self-protective circuit will kick in and shut the power supply off if the key-up voltage is too high. In that case you will get an immediate fault indication when you press the ON switch to apply power. It is useful to not have other heavy loads on the same circuit - especially loads that switch on and off (Microwave oven, household vacuum cleaner, etc.) Even if such loads do not cause the circuit breaker to open, they can cause the voltage at your outlet to shift even further. 73, Ron AC7AC -----Original Message----- > > On Feb 15, 2016, at 11:11 PM, Mike Crownover wrote: > > > > I just bought a lightly used KPA500.

Has anyone else encountered this? 73, Dick, WO1I ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to k6ll.dave at gmail.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to rlindzen at mit.edu From jim at audiosystemsgroup.com Wed Feb 17 01:41:00 2016 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 16 Feb 2016 22:41:00 -0800 Subject: [Elecraft] Pigtails on ANT1 and ANT2 UHF Bulkhead Connectors In-Reply-To: <56C3E1FC.7060009@montac.com> References: <56C3E1FC.7060009@montac.com> Message-ID: <56C415FC.9060103@audiosystemsgroup.com> On Tue,2/16/2016 6:59 PM, Clay Autery wrote: > I've decided to replace the SO-239 bulkhead connectors for ANT1 and ANT2 > with N-Connectors, but I don't want to de-solder the pigtails from the > stock UHF connectors.

Putting ferrites in the Original Microham cables improves the situation but does not solve it. I got feedback with similar problems when antennas are in close proximity, again only with Microham interfaces. Others work Be happy when in works in your environment. Lets close this thread, I found my solution that works but lost confidence in the Microkeyer II. 73s Bernhard -----Urspr?ngliche Nachricht----- Von: Joe Subich, W4TV [mailto:lists at subich.com] Gesendet: Dienstag, 16.

I've been making all my own cables for 25+ years. N-Connectors and BNC connectors are no harder and "UHF" connectors are not any easier. If you've terminated enough cables with most any series connector, it gets easier. Has something to do with the right tools and experience. Bottom Line: I did not ask anyone to offer an opinion on UHF vs N-Connectors. I asked if anyone could tell me the name of the PCB pins used on the pigtails and a wire/cable spec for the lead. It only needs to make sense to me. Thanks!

The microHAM supplied cables have been the same from the very start. Again, schematics are on the web site. The cables consist of special multi-cable bundles with six individually shielded coaxial cables and one shielded four wire cable in a common jacket. The outer jacket is cut back and the individual cables "fan out" to the appropriate jacks on the transceiver end. The mic cable is separate and in the case of the DB37-EL-K3R is two individually shielded coaxial cables. Again, the cables/interfaces work without RFI if the installation uses good engineering practice. No active external interface will be 100% "RFI free" if the user fails to keep the RF voltage well below the levels of the desired signals (~5 mV for dynamic mic audio). 73, ...

Yes... a quality Amphenol or other name maker, the right tools, and experience make them quite easy to use in terminating coax. I have also had good experience with the TImes Microwave TC series AND EZ series. The EZ series makes it "literally" a snap to do with the right strip tool and crimp dies for your frame. But the original question remains: What is the nomenclature for the pins on the leads? Heyco makes a pin that looks similar, but it is 0.187" dia... too big I'm sure.

Then tune back and forth over that frequency and listen for a drop in signal strength.

N-connectors have a well known problem with migration of the center conductor. Many, including me, consider a soldered connector superior to crimps. I note that you use crimps. Many consider a UHF connector more robust. Constant impedance simply doesn't matter below high VHF. As to weatherproofing, I would never consider ANY connector waterproof, and carefully seal all outdoor connectors. I do use some N-connectors in my station, mostly to terminate some runs of 7/8-in and 1/2-in hard line, most of which is used for long runs to HF antennas. 73, Jim K9YC From riese-k3djc at juno.com Wed Feb 17 12:42:19 2016 From: riese-k3djc at juno.com (riese-k3djc at juno.com) Date: Wed, 17 Feb 2016 12:42:19 -0500 Subject: [Elecraft] Pigtails on ANT1 and ANT2 UHF Bulkhead Connectors Message-ID: http://www.wa1mba.org/UHFconn.htm0 bob k3djc On Wed, 17 Feb 2016 09:31:28 -0800 Jim Brown writes: > On Wed,2/17/2016 6:21 AM, Clay Autery wrote: > > Please cite your authority for the "superiority" of "UHF > Connectors" to quality N-Connectors. > From wa6nhc at gmail.com Wed Feb 17 12:50:13 2016 From: wa6nhc at gmail.com (Rick Bates (WA6NHC)) Date: Wed, 17 Feb 2016 09:50:13 -0800 Subject: [Elecraft] Pigtails on ANT1 and ANT2 UHF Bulkhead Connectors In-Reply-To: References: Message-ID: Remove the trailing zero (.htm only) and the link will work.

The pin is soldered to the center conductor with a 0.050" standoff from the PE insulation. The shield is crimped to the connector shell with a 0.255" hex crimp die against the shell body leaving a slight uncrimped ring at the cable end for strain relief. Finally, the supplied or supplemental adhesive/sealant lined shrink tube is installed over the appropriate area of the crimp to offer weather resistance. The same method is used to terminate the TC-series BNC connectors. It is quite and easy process with the proper strip, de-bur, and crimp frame/dies, and provides a very consistent termination. I have used the EZ-series connectors in the past especially for static wireless point-to-point antenna feed lines using LMR-400 and larger cable. The de-burred center conductor of a properly stripped end "clicks" into the connector and crimped as above. I have feed lines on PTP installs that have been in place for 10 years using these connectors with ZERO problems. Additionally, there is a third method that some cable makers use where they use a proper die to crimp the center pin on FIRST, and then solder the pin as a secondary connection. This is generally over-kill, but I have used this method in the past for terminations that MIGHT see some rougher handling. It all depends on the specific connector design, manufacturer, cable type, installation considerations, et al. Use the right connector and tools with the right cable stock, combined with patience and skill. I DO use crimp only connectors for 75-Ohm audio/broadcast cables (Canare exclusively). Almost exclusively indoors on apps where cable will not be disturbed a lot. Proper tools/dies and cable center conductor prep as to straightness, deburring, cleaning insulator of stray shield bits, center conductor length correct for crimp well and insulator contact, et al. insure proper signal integrity and low/no leakage. ALL connectors are vulnerable to mis-handling, weathering effects, etc. And you are correct, ALL exterior connectors should be adequately protected. Personally, I use self-fusing tape or liquid products over the entire connection, and then a quality UV resistant electrical tape over that. The electrical tape is then secured at the open end with a UV resistant cable tie to guard against tape release. The principle being to restore the connection area to as close to an unbroken cable outer jacket as possible. Further, I generally use a cable stock like the Times -DB series which is impregnated with a moisture excluding substance anywhere that is tough to work on, long runs, etc... in addition to direct burial of sub-surface conduit. Bottom Line: It may be over-engineering, but I've been making cables for 25+ years; they work well and setting aside catastrophic situations; they've never failed me. But the original question remains: "What are the pins on the ANT1 and ANT2 lead ends that plug into the PCBs called?"

Message-ID: <00ee01d169af$8b6c2a10$a2447e30$@carolinaheli.com> Final edits: sorry for the resend but I keep needing to update the email as it's missing parts. Hi, I thought I had the sound issue licked with the loose case screws but I still hear the buzz. I believe I found the issue and it's NOT the speaker (well I don't believe based on my findings). Hypothesis: I strongly suspect loose transformer cores are the cause of the buzzing that are especially louder at different harmonics. Steps to reproduce and isolate the issue: 1. CW mode, Test (so no TX), Monitor all the way up (60? I think from memory..Rig is disassembled atm..). 2. Send a string of code, you can hear the tones but a buzzing, listening to received code results in the same buzzing distortion and appears harmonic. 3. Remove screws from top Cover, Hold cover in Hands, Repeat step2 - Notice NO buzzing or distortion, the speaker sounds are clear. 4. Disconnect all power/cables except ground. 5. Tap the covers, top, sides, front back, bottom, Found tapping the rear bottom results in a perceptible rattle. 6. Remove bottom covers and inspect, no discernable cause, tapping board results in a perceptible rattle. 7. Remove Fan assembly, PA-100 unit. Tapping results in perceptible rattle. 8. Inspect KLPA3A board - There's a transformer core that's loose to the board. 9. Tapping the KPA3A board results in a perceptible rattle. 10. Inspect the KPA3a board - it contains a transformer core that's loose to the board. Conclusion: I believe that using a high temperature silicon, other adhesive, or other method approved by Elecraft to secure the transformer cores to the circuit boards will resolve the issue. Request: I'd like to have an Elecraft representative review my information and make a determination as to its validity AND recommend an Elecraft acceptable solution if they agree there's an issue.

Nice article. Good references. Other than the potential center pin overheating at 1kW+, I don't see anything there of concern to me in my installation (and I can address that potential in other ways... namely, higher quality connectors with proper materials used in the pin and shell construction, plating, proper fitment to center conductor, use of appropriate solder spec, et al. Most of which I already do as a matter of course). If someday, I am running a high-power PA in the 1kW+ range, I will address this concern more completely through data acquisition at the terminations (temp monitoring) and mitigate any negative outcomes with appropriate means. Keep in mind that I am NOT maligning the UHF connector. It's cheap and effective. That's why it is used. "Cost" is lower on my engineering priority list than standardization of connector types, et al. in my station. Again, with the proper tools, materials, and experience, terminating an N (or BNC) connector is no "harder" than a UHF connector. ______________________ Clay Autery, KG5LKV (318) 518-1389 On 2/17/2016 11:42 AM, riese-k3djc at juno.com wrote: > http://www.wa1mba.org/UHFconn.htm0 > > bob k3djc From dfmaase at aol.com Wed Feb 17 13:30:19 2016 From: dfmaase at aol.com (Dan Maase AC6DM) Date: Wed, 17 Feb 2016 11:30:19 -0700 (MST) Subject: [Elecraft] KPA500 problem In-Reply-To: <102001d16870$287de460$7979ad20$@gvtc.com> References: <102001d16870$287de460$7979ad20$@gvtc.com> Message-ID: <1455733819282-7614230.post@n2.nabble.com> Mike: Suggest changing fuses in input fuse block.

(See pg 46 of the Rev H KRX3A manual.) If that pad (or the magnet shield) is missing you'll have the speaker in close proximity to the steel sub receiver enclosure and any vibration of the top cover would be coupled to the sub receiver itself.

Even after wedging the ferrite beads I can get the case to buzz harmonically if I lower the monitor tone significantly. I'm happy because it works where I listen. Once I finish with Morse Academy classes it will probably be rare for me to use the built in speaker. I would like a permanent fix for it but that's probably not going to happen. I'm feeling pretty bad about the whole thing but am throwing in the towel. I'm cursed with being a technician, engineer, and now a systems analyst. It's hard for me to let go of things that should work. Why have an internal speaker if the case has loose components/audio harmonics that will result in distortion. Why have a monitor adjustment that will go to 60 if you are going to question WHY a customer want's it that high. (I have hearing loss from the Navy). Why deny there's an issue when recent forum posts and reflector posts ? Chalked up to "bent speaker", "old dsp code".etc.. They've offered for me to send it in for their repair/review -( presumably at my expense for shipping, I'm east coast.. ) or replace the speaker. I find it interesting that nobody at Elecraft seems to be able to reproduce the issue. At this point I'm going to just glue the ferrite beads down and chalk it up to bad engineering and apparently I'm the only person in the world with a new K3S that does this. I'm still happy with the radio and would probably still buy it again. I am starting to question overall value to cost. To be fair I believe Howard has done all that he can. I also believe Elecraft has either an image to uphold or a K3s audio reputation to repair. If Elecraft will be at the Charlotte, NC Hamfest I might just cart my rig up and show it off. Might be interesting to see what the sales folks say.

But I have just added it to the list, because I AM using the internal speaker. External speakers are on the list, but some way down, so I will be using the internal speaker (or actually phones) for some time. In all fairness, I would think this issue is only rarely an "issue" for the VAST majority of ops... Between external speakers, not having the PA to begin with, or using headset/phones, most folks probably don't use the internal speaker at audio levels sufficient to reproduce the issue. I would prefer to do the fix myself than to have the additional labor involved in fixing the beads/conductors down (and the accompanying increase in price/avail of PA modules). I examined my K3s closely as I assembled it... I consider it a supremely well-engineered piece of equipment and worth every penny I paid. :-) Have a super day! ______________________ Clay Autery, KG5LKV (318) 518-1389 On 2/17/2016 1:57 PM, Jerry Moore wrote: > Have you done this ? > From mike at ve3yf.com Wed Feb 17 15:20:26 2016 From: mike at ve3yf.com (Mike VE3YF) Date: Wed, 17 Feb 2016 20:20:26 +0000 Subject: [Elecraft] WTB P3 With SVGA Adapter Message-ID: <82f78063-d9c6-4105-b0b3-ec8c3018d8a1@getmailbird.com> I have found a P3.

I do not believe "currently" there is a way to make this happen via macro commands. ? If you perform the needed steps by hand, with lots of space between commands, it works, if you then place the exact same commands in a macro it fails. I tested by placing each command below in its own macro key using the P3 Macro tester software included with the P3 utility. ?Here is an example: I have a DX station at 14.010, and I want to move 14.010 to the left edge of the P3, showing the upper 5 KHz ra Macro 1: #SPN000100; Sets span to plus and minus 10 KHz. Macro 2: UP7; Moves K3 up 5 KHz. Macro 3: #FXT1; Places the P3 in sticky mode, (Fixed Tune), locking the transmit frequency to the center of the P3 screen. Macro 4: DN7; Moves the K3 down 5, dragging the transmit freq down with it, and putting the transmit freq on the left edge of the P3, exposing the upper 10 KHz of the signals on the P3. If I then fire them one at a time, everything works as expected, the transmit frequency is on the lower left edge for an up split. If I place them in a single macro, it fails, every time... 73's, and thanks, Dave For software/hardware reviews see: http://www.nk7z.net For MixW support see: https://groups.yahoo.com/neo/groups/mixw/info For SSTV help see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Wed, 2016-02-17 at 12:30 -0600, Grant Youngman wrote: > You could -- > > Tune up 1/2 of your span width (in your example up 2.5 kHz).

If you intend to feed a multi-band antenna with open wire line, you'll need some sort of tuner at the point where you transition from open wire to coax: - if you plan on doing that out near the base of your antenna (the most efficient spot) then save your money and purchase an auto tuner, e.g., an LDG Z11 ProII, and place it at the point where the open wire line transitions to coaxial feed. - if you plan on doing that inside the shack and can keep the coaxial run short, the internal auto tuner would work, albeit you could employ an LDG Z11 ProII there as well. If you plan on feeding any multi band antenna with coax of a length longer than 10' to 15' an auto tuner inside the shack isn't worth much -- place an LDG Z11 ProII style auto tuner at the base of the antenna, 'tween the coaxial fee line and the antenna feed point and call it a day. If you plan on taking the K3S on portable trips....its auto tuner wud be 'da way to go, as long as you keep coaxial runs 'tween the K3S and the antenna feed point short...."short" means < 10' to 15' or so. 72 de Jim R.

Tape/silicon the ferrite beads on both boards and install x5 30mm strips of black tape in specific places. Easy fix.

No, I have not done this mod. But I have just added it to the list, because I AM using the internal speaker. External speakers are on the list, but some way down, so I will be using the internal speaker (or actually phones) for some time. In all fairness, I would think this issue is only rarely an "issue" for the VAST majority of ops... Between external speakers, not having the PA to begin with, or using headset/phones, most folks probably don't use the internal speaker at audio levels sufficient to reproduce the issue. I would prefer to do the fix myself than to have the additional labor involved in fixing the beads/conductors down (and the accompanying increase in price/avail of PA modules). I examined my K3s closely as I assembled it... I consider it a supremely well-engineered piece of equipment and worth every penny I paid. :-) Have a super day! ______________________ Clay Autery, KG5LKV (318) 518-1389 On 2/17/2016 1:57 PM, Jerry Moore wrote: > Have you done this ? > From k6dgw at foothill.net Wed Feb 17 16:51:47 2016 From: k6dgw at foothill.net (Fred Jensen) Date: Wed, 17 Feb 2016 13:51:47 -0800 Subject: [Elecraft] Amp or tuner / Chicken or Egg In-Reply-To: <1455744717620-7614247.post@n2.nabble.com> References: <56C4E22F.4833.26C16EF6@Gary.ka1j.com> <1455744717620-7614247.post@n2.nabble.com> Message-ID: <56C4EB73.2070305@foothill.net> I don't think that's what he asked.

Loose screws, speaker fastening not being solid, speaker shield, missing foam pad under speaker over KXRX3: all of these have been addressed, but I don't remember the center stiffener being the culprit before. You have now added another item in the list, but the entire list is the result of people like yourself, tirelessly tracking done the source of some anomaly and reporting it to the support staff.

Since the KAT3 tuner is just a plug-in, I'd suggest installing it and the KPA3 shield first (do everything in the KPA3 instructions down to "Installing the KPAIO3A Interface Module"), since the both require more mechanical disassembly. Put everything back except for the K3 top cover and check out the KAT3 at 10 watts (don't forget to enable the KAT3 as described on the last page of the installation instructions!).

If they aren't broken, then build resonate antennas. They just work the best.? Well, not everyone has the luxury of enough real estate for a bunch of resonant antennas. When one wants to be able to operate multiple HF bands, a multi-band antenna (like a doublet), with tuner, works quite well. I, for one, would love to have several towers with resonant yagis, quads, etc. But living on a standard city lot with CCR/HOA restrictions pretty much sets a limit on what sort of antenna(s) can be erected. I use an 88 foot long doublet (skinny wire, stealthily hung in the trees) fed with home brew 600 ohm ladder line. It works great and I can operate on 60 - 6 meters with it. Without a tuner, that would not be possible.

I have the ATU kit and the amp kit in my hands, I'm not sending them back. Why I want an ATU has nothing to do with my question. FWIW, I do have resonant antennas; all of them from 160 through 10 are resonant. I sometimes take the radio out where I use a random wire. It's difficult to make a random wire resonant when I'm on a trip. When you buy an assembled K3S, you do not get an assembly manual with it. I guess I could download the Pdf but do I want to do things in the same order as if I were assembling a K3s kit or when adding two separate but related modules to an assembled K3? I don't know. All I asked was; in an already assembled K3s/10, which of the two should I install first. A couple of replies have said I should install the ATU first. That's what I'll do. Thanks to all that replied. 73, Gary KA1J > Just got my factory assembled K3s/10 delivered. I need to install the > 100W amp and internal tuner.

The K3/K3S uses the enclosure to assure the best shielding. When you add that tape, you are reducing the points of contact between the covers of the K3 and the internal shields. The impact of the tape may be small in your particular case, but may not in other cases. It is dependent on just how much RF is floating around in your shack when you transmit. 73, Don W3FPR On 2/17/2016 4:49 PM, Jerry Moore wrote: > I had someone contact me off list to suggest putting some small bits of tape > where the cover touches the center stiffener.

The assembly manual tells builders to build up the K3S with the LPA first, then do the 5 watt calibration - that has already been done for you in your K3S/10 Factory assembly. After that, install the KAT3 (if you have it), and then install the KPA3, and then do the 50 watt TX Gain Calibration. That order is not really important because there is no direct relationship between the KAT3 and the KPA3. You might want to check the K3S assembly manual and turn to the parts after the 5 watt TX Gain calibration has been done and proceed from there. I say that only so you have a sensible guide to completing your assembly with the KPA3 and KAT3. 73, Don W3FPR On 2/17/2016 4:12 PM, Gary Smith wrote: > Just got my factory assembled K3s/10 delivered.

Just the fact that elecraft won't officially acknowledge the issue OR that you've not personally seen it doesn't mean it doesn't exist. Do a little research then come back and tell me nobody else has the issue. I'm just venting a bit but my plans to buy the sub RX are on hold indeterminately. I've been in support for a very long time and know the difference between operator error/ID10T and an issue. What puts me off the most is posts like yours that assumes because you haven't heard or seen the issue then it must not exist over the entire 11k user base. The reality is that you don't have the knowledge to support that AND most ops apparently use a headset/external speaker. I'd think the manufacturer of a $3500 radio (what I bought) would have a bit more pride to fix issues rather than ignore/discount/punish customers. Anyway, I'm putting myself in time out because the general consensus seems to be that I'm a complete idiot with a speaker buzzing sound that none of the other 11k users can hear because they don't use the speaker even after I've taken the time to logically and methodically spell out steps to reproduce the issue and my findings. I'm not answering email on this for a few days until my blood pressure comes down.

I'm sorry you lost your "Warm, Fuzzy" feeling for Elecraft. But, in all due respect, this is the first time I've heard this issue come up. So, if it is not an issue for the other ~11,000 owners, how is it that they should have a "ready fix" for the unusual example? Loose screws, speaker fastening not being solid, speaker shield, missing foam pad under speaker over KXRX3: all of these have been addressed, but I don't remember the center stiffener being the culprit before. You have now added another item in the list, but the entire list is the result of people like yourself, tirelessly tracking done the source of some anomaly and reporting it to the support staff. I feel certain that if this was seen as a potential problem, it would have been addressed long before now. There are a lot of K3 and K3S radios out in the world and "Stuff happens". I hope in the end, that you will like your radio as much as I like my two. ...bill nr4c On Wed, 17 Feb 2016 16:49:35 -0500, Jerry Moore wrote: > I had someone contact me off list to suggest putting some small bits > of tape where the cover touches the center stiffener.

I have worked with David Anderson, GM4JJJ, on setting up my KX3 trying to minimize the connecting and disconnecting of cables to my Focusrite 2i2 sound card. The more I thought about the advice he gave me, the more curious I became. I got to the point of could I connect my K3 too? Problem is that I know very little about audio mixers so please go easy on me. I have been reading and looking online for several days now. I have read through Jim Brown?s, K9YC, documentation on his page and I can handle what needs to be done there. Here?s the potential scenario: I have a K3 and a KX3. I have one sound card to share between the two of them. Yes, I do realize that just adding another sound card may be the simplest thing to do at this point. I have thought of that and that solution is not off the table. I have the Focusrite 2i2 sound card. This is a fairly new purchase and so far I am pleased with its performance. I have a mic for each radio - the MH2 for the K3 and the MH3 for the KX3. I could see where going to just one studio-type mic would be beneficial. With the TX and RX EQs in both radios, I really do not need the parametric EQ of a mixer. I also use an FM-only VHF radio for local repeater contacts but consider it out of scope. What I have been looking at is an 8-channel audio mixer (either the Mackie ProFX8v2 or the Alesis Multimix 8 USB). My thoughts are: Install a single mic into mic input one on the mixer. This mic would serve both the K3 and the KX3. Have the LINE OUT from the K3 into Inputs 3 and 4 Have the SPKR OUT from the K3 into Inputs 5 and 6 Have the SPKR OUT from the KX3 into Inputs 7 and 8 Have the Focusrite 2i2 LINE IN L and R to Main Out L and R on the mixer Have the Focusrite LINE OUT L to Input 2 on the mixer. Now I run into trouble. The Mackie has ST (studio?) return. I could run the L to LINE IN on the K3 and R to MIC IN on the K3 but I cannot figure out how to get MIC IN wired to the KX3. The Alesis adds an AUX SEND. Could I use that to feed the MIC IN of the KX3? I realize this borders on off-topic for this group so if you?d rather respond directly, I understand and I apologize for using the bandwidth for what may seem like an off-topic subject to some. 73, Joel - W4JBB From tnnyswy at yahoo.com Wed Feb 17 17:59:50 2016 From: tnnyswy at yahoo.com (tnnyswy at yahoo.com) Date: Wed, 17 Feb 2016 22:59:50 +0000 (UTC) Subject: [Elecraft] Amp or tuner / Chicken or Egg In-Reply-To: <77DDA8ED-EFB1-47F3-94F0-3F26E7871CD6@me.com> References: <77DDA8ED-EFB1-47F3-94F0-3F26E7871CD6@me.com> Message-ID: <599380759.6216904.1455749990916.JavaMail.yahoo@mail.yahoo.com> Jim!

If they aren't broken, then build resonate antennas.? They just work the best.? Well, not everyone has the luxury of enough real estate for a bunch of resonant antennas. When one wants to be able to operate multiple HF bands, a multi-band antenna (like a doublet), with tuner, works quite well. I, for one, would love to have several towers with resonant yagis, quads, etc. But living on a standard city lot with CCR/HOA restrictions pretty much sets a limit on what sort of antenna(s) can be erected. I use an 88 foot long doublet (skinny wire, stealthily hung in the trees) fed with home brew 600 ohm ladder line. It works great and I can operate on 60 - 6 meters with it. Without a tuner, that would not be possible.

To avoid it, I use a Shure Model SCM800 8/9 input mixer ($50 to $150 on that auction site) and a Dave Clark headset. I have audio on demand from 4 hf rigs, a vhf/uhf rig, and XM radio. Not a word of complaint from the XYL when I listen to 2 or more sources at once! Antennas managed by two MFJ 6-in/6-out switches. Now I just need to do something about the key! I am considering using an old RS-232 mechanical switch to solve that problem. I don't do microphones. BTW, everything is mounted in standard 6 foot relay rack, on wheels for easy access to rear.

I have worked with David Anderson, GM4JJJ, on setting up my KX3 trying to minimize the connecting and disconnecting of cables to my Focusrite 2i2 sound card. The more I thought about the advice he gave me, the more curious I became. I got to the point of could I connect my K3 too? Problem is that I know very little about audio mixers so please go easy on me. I have been reading and looking online for several days now. I have read through Jim Brown s, K9YC, documentation on his page and I can handle what needs to be done there. Here s the potential scenario: I have a K3 and a KX3. I have one sound card to share between the two of them. Yes, I do realize that just adding another sound card may be the simplest thing to do at this point. I have thought of that and that solution is not off the table. I have the Focusrite 2i2 sound card. This is a fairly new purchase and so far I am pleased with its performance. I have a mic for each radio - the MH2 for the K3 and the MH3 for the KX3. I could see where going to just one studio-type mic would be beneficial. With the TX and RX EQs in both radios, I really do not need the parametric EQ of a mixer. I also use an FM-only VHF radio for local repeater contacts but consider it out of scope. What I have been looking at is an 8-channel audio mixer (either the Mackie ProFX8v2 or the Alesis Multimix 8 USB). My thoughts are: Install a single mic into mic input one on the mixer. This mic would serve both the K3 and the KX3. Have the LINE OUT from the K3 into Inputs 3 and 4 Have the SPKR OUT from the K3 into Inputs 5 and 6 Have the SPKR OUT from the KX3 into Inputs 7 and 8 Have the Focusrite 2i2 LINE IN L and R to Main Out L and R on the mixer Have the Focusrite LINE OUT L to Input 2 on the mixer. Now I run into trouble. The Mackie has ST (studio?) return. I could run the L to LINE IN on the K3 and R to MIC IN on the K3 but I cannot figure out how to get MIC IN wired to the KX3. The Alesis adds an AUX SEND. Could I use that to feed the MIC IN of the KX3? I realize this borders on off-topic for this group so if you d rather respond directly, I understand and I apologize for using the bandwidth for what may seem like an off-topic subject to some. 73, Joel - W4JBB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to ktalbott at gamewood.net From Gary at ka1j.com Wed Feb 17 19:06:28 2016 From: Gary at ka1j.com (Gary Smith) Date: Wed, 17 Feb 2016 19:06:28 -0500 Subject: [Elecraft] Amp or tuner / Chicken or Egg In-Reply-To: <1455752048280-7614267.post@n2.nabble.com> References: <56C4E22F.4833.26C16EF6@Gary.ka1j.com>, <56C4F9BC.8421.271D6AE0@Gary.ka1j.com>, <1455752048280-7614267.post@n2.nabble.com> Message-ID: <56C50B04.18350.2760EF0E@Gary.ka1j.com> No worries Jim, I found out what I needed to know before proceeding, thanks for the reply.

Can we all just step back for a second? This list, at times, can be downright infuriating to those of us who ask a question in good faith, only to have the thread go off the rails in a matter of minutes. I've been victimized countless times. When it happens I say to myself, "Well, there goes any hope of getting an answer to my question." This list is no different than any list -- you have your Curmudgeons, your Know-it-Alls, the Complainers, the Alligators, etc., etc.-- and this tends to make people gun-shy or at least very tentative about posting. I can't blame them. Maybe we need to view each post primarily as a *request for help with a specific problem*, and not really as an invitation to expound, discuss, and bloviate. Simply this: Let's make sure the Original Poster always gets our best in the most direct and expedient manner. There are a handful of guys who regularly stick to this rule and my hat's off to them for the dozens of times they've patiently come through for me. I stick around here mainly to pay back by helping others when I can. Replying off-list is fine. Certainly we're not losing any learning opportunities if we choose to do this for the common questions ("What's the best pair of gym shoes to wear while using my K3?") and I've had some of my best technical exchanges off-list, which I'm sure is true of a lot of us. If you don't get a satisfactory answer here probably the best thing is to then go contact Elecraft support privately. Ultimately, this list doesn't replace Support. One more thing, and this is directed to the Original Posters out there: There is nothing in the Elecraft list guidelines that says you *must* post the resolution of a problem to the list, but common courtesy probably dictates that you do so. A single wrap-up message by the original poster would seem sufficient: "My problem was caused by two mourning doves that nested in my balun enclosure." I was left hanging in the past month by two baffling but fascinating problems that I fear we'll never understand... Whatever happened to that K3 that was hearing broadcast stations by E.S.P.? Was that Wayne's new psychic firmware?? Self-moderation is definitely part of the solution. Here are two guidelines that if followed diligently could benefit us all: 1. If your response contains the sentiments, "Me too," or, "Why do you want to do that?" it probably isn't worth sending. Or maybe should be sent off-list. 2. Delay all responses overnight. If the next morning your response still seems needed, go ahead and send it. Finally I would like to add that, if there's a thread not to your liking, kindly spend the few seconds deleting it rather than adding yet another post to an already long thread complaining that the thread is getting too long or too off-topic. It's kinda like yelling, "Quiet!" in a noisy theater-- it doesn't accomplish anything, and it just makes the problem worse. This is all personal opinion and I welcome Elecraft telling me I'm full of beans as they see fit. I'll even post a resolution message reporting how many people told me, off-list, to go take a flying leap of a galloping goose.

Please save this for future reference. The most important thing to remember is that this is a hobby - Let's have fun! The PRIMARY purposes of this list are to provide a polite and enjoyable forum for discussing Elecraft products, share mods, new ideas, feedback to Elecraft, share experiences using our products, troubleshooting ideas etc. The Elecraft email list server (reflector) is provided to further the discussion of Elecraft products and related items. It serves as a forum for the discussion of both technical and operating topics including product features, construction and debug problems, sharing your enthusiasm and impressions from using our products and more general ham radio related topics of interest to our customers. (Please -strongly- resist the urge to reply to an OT topic once it has gone to 5 posts. Once it hits ten posts do not reply at all (go off list if you feel the urge to continue.) Also, please do not try to always get the 'last word'.. 1. YOU MUST BE SUBSCRIBED to the [Elecraft] list TO POST to it. (This is done to stop advertising spammers from hitting the list.) Any postings sent to elecraft at mailman.qth.net by addresses different from the exact ones it shows as subscribers will be rejected. This includes alias (forwarded) addresses like w1xyz at arrl.net. If you use an alias to subscribe you must have it as your from: and return address too. Subscribing with w1aw at arrl.net from your physical address of joe at aol.com will allow you to receive postings, but your postings to the list will be rejected if their from: and reply to: address does not match your subscribe address.. Go to http://mailman.qth.net/mailman/listinfo/elecraft to subscribe and to change your list preferences. To unsubscribe or to change your list preferences (digest, no mail on/off etc.), scroll to the bottom of the page and log in with your subscribed email address and the password that was sent to you by email when you subscribed (and sent to you each month). 2. If you want to provide an attachment, .JPG picture or other large file for use on the list, first post it to your personal web page and then post a link to its address in an email to the list. The list strips all attachments to prevent viruses from propagating and to keep the archives at a reasonable size. 3. Top posting is the official standard for this list, and its especially important for those of us who also read our email on smartphones, iPads etc. Scrolling though a long thread before getting to the reply text is difficult on these devices and costs everyone a lot of time. Reading the response first, at the top, is a huge time saver, especially when you have to read hundreds of emails daily as we do here. We really appreciate your adherence to this. Please also delete -all- footers and as much of the prior email text as possible when replying to cut down on overall email size. Please keep the amount of copied text from previous posts to an -ABSOLUTE MINIMUM- in your replies. 4. EMAIL OVERLOAD: If you are overloaded by the volume of individual messages on the list, You can view the daily Elecraft list messages for each month in web format at: http://www.elecraft.com/elist.html . These archives are updated hourly and list postings by subject. (the Nabble archive looks very useful.) Just click on the ones you are interested in to read. You can also set your Elecraft list email preferences to 'no mail' delivery, which still allows you to post to the list when reading via the digest. You can also change your subscription to the DIGEST version, which sends you a single compilation each day. To change your email list options or to subscribe / unsubscribe, go to: http://mailman.qth.net/mailman/listinfo/elecraft Scroll to the bottom of the page to log into your preferences page and set your mail options to 'no mail'. 4a. Please make an effort to keep list volume under control by resisting the urge to post a comment on every long discussion thread (CW, Soldering etc.) With thousands of list subscribers volume can quickly get out of control if everyone feels the need to comment. While we do not overly restrict the subject matter on this list, please remember that its primary focus is on Elecraft products, and their use. Many people rely on it for pointers on building, using and troubleshooting their rigs. Other ham Radio topics are OK, but please keep the posts on non-Elecraft topics under control. 4b. *** When emailing about a specific rig or option, please add the rig/option name(s) to the first part of your email subject line. (K1, K2, K3, KX1 etc.) This will be a huge help for those experiencing email overload and will allow automatic filtering based on subject line. Examples: "Subject: [K3] Filter Options" "Subject: [KX1] How to use ped portable?" "Subject: [XG2] Wow! Its a big help. 5. *** IMPORTANT - PLEASE KEEP ALL POSTINGS CORDIAL. Restrain the urge to email someone admonishing them about a posting, or snidely commenting on it. The last thing we want to do is to scare anyone off the list. Overly aggressive postings, arguments and negative comments about other posters only serve to scare away new potential Elecraft community members. Waiting over night before hitting 'send' really helps to put things in perspective.. Remember that -everything- you post here is archived and publicly visible for as long as the internet exists. Do you really want your friends, employers, kids etc. reading what you just posted in anger, foolishness, arrogance etc? If you have a complaint about someone or a thread please email it directly to me ( eric at elecraft.com ) and I'll address it. Please do not post complaints about other postings to the list. 5a. Do not post publicly or privately asking people to stop a particular thread, no matter how long, off topic or repetitive it gets. Email me instead. I will step in when I feel it is necessary to end a thread. (eric at elecraft.com) 5a1. Please exercise restraint in posting when a thread is getting heavily covered. 10-15 posts on one topic in a day is excessive. Please do not vote yay/nay or with 'me too' postings. That only clogs our email in-boxes. 5b. Please do not post any direct attacks or snide comments directed at a list member. Enthusiastic arguments are encouraged, but please keep everything cordial. Members who verbally attack or denigrate another (either via the list or via direct email) may be removed from the list. As the only official list moderator, I'll jump in as necessary to keep everything orderly. I do this off line and occasionally to the list when it is appropriate. Our goal is to keep the Elecraft list a fun, relaxed and informative central clearing house for Elecraft information and enthusiasm. 6. There are -no- stupid questions. Please feel free to post your technical questions and comments to the list. (And absolutely do not criticize posters for their questions either on list or via direct email.) Elecraft owners are your best source for quick answers (and they NEVER sleep!) If you don't get the answers you need from the list please email us direct at support(at)elecraft.com , which is our customer service address. We do try to watch the list traffic, but we may not respond to everything immediately and may miss some postings sent to the list or our personal addresses. 7. Please do post your experiences with your Elecraft kit, DX worked, crazy ideas, product ideas, complaints (yes - we do want to hear them, but please keep it polite . 7a. Commercial postings are allowed if they relate to Elecraft products, QRP, QRO, home-brewing, building etc. and are of interest to this list's membership. Please keep them as short as possible and provide web links to more detailed information. I'll step in if we feel someone is posting too many messages of this type. 7b. Please limit commercial postings to one per month per offering or product area (i.e. Builder for Hire postings, ham radio related products etc.) 8. Also, please -DO NOT USE CAPS- to emphasize words or phrases. This is interpreted as shouting rudely on the internet. If you want to emphasize something, surround it with -dashes-. 9. Send parts requests direct to parts at elecraft.com, instead of to the list. 10. If you don't get an answer to a question from the list, or by searching the list archives, don't forget to check the Builder's Resource Page at http://www.elecraft.com and our support email address: support at elecraft.com 11. Please note that Wayne, I and our support staff do not read 100% of the emails on this reflector - especially when we are busy at hamfests, ramping up new products in production etc. If you expect us to reply to a posting, and we do not do so, please email us directly or contact our great guys at support at elecraft.com 12. And above all, HAVE FUN!. We hope that this list is both a good technical resource and that it serves as a Elecraft community gathering place. We enjoy reading it every day and it really helps us keep our energy level high so we can continue getting exciting new products out the door to you! 73, Eric WA6HHQ Elecraft COO, List Moderator, Modulator etc. From k9jri at mac.com Wed Feb 17 21:17:02 2016 From: k9jri at mac.com (Michael Blake) Date: Wed, 17 Feb 2016 21:17:02 -0500 Subject: [Elecraft] KX3 Knob Removal In-Reply-To: References: Message-ID: Don and Craig, thanks for the input.

You should feel good that you contributed to the process. I am sure someone in the loop is monitoring this thread and making notes for possible documentation/design changes. As it turns out, YOUR buzzing had/has multiple components sourced from multiple causes. Adding chassis stiffener vibration isolation to the list... although that would be an issue requiring just the right combination of stiffener and top cover bowing in the correct directions to create and interstitial interface such that certain frequencies setup a sympathetic/harmonic vibration. Reminds me of the days I used Sorbothane to mount HDDs, fans, et al. in tower chassis to reduce vibrations and other noise. No one was doing it then... lots of folks do it now. ______________________ Clay Autery, KG5LKV (318) 518-1389 On 2/17/2016 3:49 PM, Jerry Moore wrote: > I had someone contact me off list to suggest putting some small bits of tape > where the cover touches the center stiffener.

I've reported a few defects to Elecraft over the last 8 years. Usually they get fixed and are sometimes folded into production. There are thousands of guys using K3s that include a fix that was developed using my radio as a prototype after I demonstrated it to an Elecraft engineer. (It also involved vibration by the way and two months in the Elecraft hospital) I've had similar experiences recently with the same chorus singing, "We don't see it here", when I reported issues with the ARRL NPOTA website and the software for my DG8SAQ network analyzer. Even posting screen shots won't convince some of the naysayers. It takes one other guy saying he sees it too, then it gets addressed. In the DG8SAQ case, he saw it personally and fixed the software. Of course, he's competent, the ARRL problem is ongoing. Don't let them get you down.

I used a SoundCraft EPM-8 (EPM-6) will also work. The 8 says 8 channels, but it?s really 12. 8 mono and 2 stereo. Right now I only have KX3, a nice used K3 is in the very near future and is why I set this up. Channel 1: Microphone Channel 2: Output from USB sound card Channel 7: Receive main from KX3 Channel 8: Receive sub from KX3 Aux 1: Mic input to KX3 Monitor Left: Left speaker Monitor Right: Right speaker Master Mix Left: RX Main for USB sound card Master Mix Right: RX Sub for USB sound card The K3s will plug in as follows: Channel 5: Receive main from K3s Channel 6: Receive sub from K3s Aux2: Mic input to KX3. I can mute individual channels, adjust volume and EQ for each. I can dial down the monitors so I?m not hearing the speakers if I want to be silent during digital modes. Also using the faders on channel 1 and 2, I can mix it into the monitors during transmit so I can hear myself. I will have make a box to switch the PTT, keyer to the proper radio. Not a big deal. The other cool thing is I can adjust what I hear in each ear of the headphones when running Dual watch on the KX3. Plus I can swap the ears with a turn of the knob so the watch matches what I see on the PX3 (e.g. which ever frequency is lower goes to the left ear, the higher frequency goes to the right). That way ears match the visual. Most of this setup came from W3YY (http://w3yy.com/audio_control_system.htm). He has it setup with isolators and level shifters since pro equipment runs at higher levels than consumer. I also used the isolators and line level shifters. Works well. I?m planing on setting the headphone output of the computer into one of the stereo channels. That way I can use the same speakers for music when I?m not on the radio. 73, Joe - KO8V > On Feb 17, 2016, at 5:28 PM, Joel Black wrote: > > Yep, I?ve looked and there is a *lot* of information on this reflector about the subject. > > I have worked with David Anderson, GM4JJJ, on setting up my KX3 trying to minimize the connecting and disconnecting of cables to my Focusrite 2i2 sound card.

I have one sound card to share between the two of them. Yes, I do realize that just adding another sound card may be the simplest thing to do at this point. I have thought of that and that solution is not off the table. I have the Focusrite 2i2 sound card. This is a fairly new purchase and so far I am pleased with its performance. I have a mic for each radio - the MH2 for the K3 and the MH3 for the KX3. I could see where going to just one studio-type mic would be beneficial.

If there is, it thinks it is in TX mode even if the rig is not in transmit. I had that problem and it was a poorly soldered resistor on the front panel board, but a shorted TX line (RCA cable) would do the same thing. Elecraft replaced the board. You should not have an asterisk when you switch to operate until you key the transmitter.

It has two stereo mixing busses, Main and Sub, so really four channels. You can route any input to either or both and fade from left to right as you wish. I have all the sources from rigs and the PC sound card and mics going to inputs. I route anything I want to transmit with to the Main mix and take those outputs, through attenuators to the inputs to the rigs, in my case, left to one rig and right to the other. I route anything I want to hear to the Sub mix and have the headphones and external speakers connected to that. This is very flexible, I guess I could even set up a crossband repeater where it was legal to do so! The sub mix also goes to a tape out to the pc sound card input, so I can record off the air and play back what was recorded. There are many mixers with this type of setup. I bought this one used on Craigslist. It does not have a USB interface, which is desirable, so it was not too expensive. I also use the usb audio interface to the rig, in my case another manufacture's but the K3s has usb also. You wind up with many sound cards in the PC, and most programs allow you to choose the input and output sound card. If you screw up with the selections you can get awful feedback! 73, Mark W7MLG On Thu, Feb 18, 2016 at 9:12 AM, Joe DeVincentis wrote: > I?m using a mixing board for my setup as well.

No replies, try again Message-ID: <56C6B31A.2040608@storm.ca> Don, as described that was NOT the opposite sideband. On the video the stronger signal was at 14091.883 kHz on the dial. That is the frequency of the mark tone; the space tone would have been at 14091.713 kHz. The pitch in use was 915 Hz mark, so the suppressed carrier frequency would be 14092.798 kHz and the center of the filter bandpass (the notch in the dual passband filter pattern) would be at 14091.798 kHz (1000 Hz below the suppressed carrier). The second slightly weaker signal in the video was at 14091.720 kHz, i.e. the higher of its two tones was virtually coincident with the lower of the two tones from the first signal, and the second tone would be 170 Hz lower, at 14091.650 kHz. A true opposite sideband signal response would have been at 14093.713/14093.883 kHz, nowhere near what was observed. This resembles audio IMD more than an opposite sideband response. For example, a heavily overdriven audio signal with two overlapping simultaneous tones at 915 Hz and 1085 Hz might develop spurs at 745 Hz and/or 1255 Hz, and one of those spurs combined with one of the intended tones in the first signal would look a lot like the second signal in the video. My next question would be, do you see something similar if the dual passband filter option is turned off, or only when it is turned on? I am wondering whether some kind of aliasing phenomenon could exist in the dual passband filter that might account for this. 73, Rich VE3KI W3FPR wrote: > For strong signals the filtering may let some of the opposite sideband > get through the filters. > What is the relative S-meter reading for the true sideband and the > opposite sideband?

Yes, I do realize that just adding another sound card may be the simplest thing to do at this point. I have thought of that and that solution is not off the table. I have the Focusrite 2i2 sound card. This is a fairly new purchase and so far I am pleased with its performance. I have a mic for each radio - the MH2 for the K3 and the MH3 for the KX3. I could see where going to just one studio-type mic would be beneficial. With the TX and RX EQs in both radios, I really do not need the parametric EQ of a mixer. > From aj4tf at arrl.net Fri Feb 19 06:34:47 2016 From: aj4tf at arrl.net (aj4tf) Date: Fri, 19 Feb 2016 04:34:47 -0700 (MST) Subject: [Elecraft] Tx Gain Cal failed Message-ID: <1455881687202-7614318.post@n2.nabble.com> Hello, New build, K3S s/n 10669. Everything went well, but when I got to the TX Gain calibration (low power) something isn't quite right. Using the K3 Utility (ver. 1.15.6.27), the utility says that the "power won't settle" and won't get past the 160m band. Watching it, the displayed power value fluctuates around 5.0 W. You can see it in this video: https://youtu.be/mKK9PYv8fFg Manually setting the band, and doing the tune at 5W setpoint shows pretty much the same thing on every band ... the displayed power 'hunts' around 5W. The power measured at the external power meter, however, does not seem to be moving, it is pretty stable. Reported SWR is 1.1 : 1. This radio does not have the KAT3 in it. The 100W amp is not yet installed. Firmware: MCU 5.38; FPF 1.25; DSP 2.86 Any advice would be appreciated.

No replies, try again Message-ID: <56C73339.5080501@cableone.net> Mike, What I see in your video is that you have the RTTY signal properly tuned at 14,091.883. "Properly tuned" means that you have the Mark energy and the Space properly aligned in the dual passband filter and the data conveyed by the mark and space energy is being decoded and displayed. In a normal "ham radio" RTTY signal the RF energy for the Mark and Space is 170 Hz apart, with the Mark frequency 170 Hz higher, in RF terms, than the Space frequency. When demodulated by a receiver operating in Lower Sideband (LSB) mode, this results in two audio tones, with the audio tone representing the Space energy 170 Hz higher than the audio tone representing the Mark energy. In the video, when your radio is tuned to 14,091.883, the tone representing the Mark energy is passing through the "Mark" side of the dual passband filter and the tone representing the Space energy is passing through the "Space" side of the dual passband filter, and the RTTY data is decoded properly. When you tune down to 14,091.720 in the video, a 163 Hz difference, you have the tone representing the Space energy passing through the "Mark" side of the dual passband filter and the tone representing the Space energy is outside of either portion of the dual passband filter. There is no anomaly revealed in your video, that's just the way that RTTY, the receiver, and the dual passband filter works when you tune away from a properly tuned RTTY signal. The reason the data on the Space tone sounds like an inverted version of the data on the Mark tone is because that is exactly what it is. In an RTTY signal, the same data is carried by the both the Mark and Space energy and the state of one is the inverted state of the other. 73, Bill - NA5DX Message: 23 Date: Thu, 18 Feb 2016 09:56:06 -0700 From: Mike Murray To: "Wes (N7WS)" Cc:elecraft at mailman.qth.net Subject: Re: [Elecraft] K3 - AFSK anamoly?

When you tune across an RTTY signal using your 400 Hz filter with the dual passband filter turned off, first one shift, either Mark or Space depending on the direction you are tuning, will enter the passband of the filter and then both shifts. Assuming you have the Shift control on the front of the K3 centered, when the Mark and Space energy is centered on either side of the center of the filter (and the decoder), the RTTY will decode properly. Besides seeing the decoded text, the CWT indicator in the meter area of the K3 display will show you when you have the Mark and Space energy centered for proper decode. As you continue to tune same direction, you will lose the first shift you acquired as it passes out of the other side of the filter passband, and then finally you will lose the other shift as you continue to tune away. 73, Bill - NA5DX On 2/19/2016 10:06 AM, Mike Murray wrote: > Bill, > > Excellent analysis and I suspect you are correct in exposing my > current, very limited knowledge of RTTY signals.

He explained that before Elecraft settled on the KPA500 they built three different sized prototype amplifiers for proof of concept and to establish the cost for each. He explained that when that effort was complete the KPA500 was thought to be the best fit for the market at that time. When a member of the audience asked what happened to the legal limit amplifier, Eric replied that it was in his shack. Eric can correct me if I have failed to remember his presentation accurately. 73, Bill - NA5DX From k2av.guy at gmail.com Fri Feb 19 15:30:19 2016 From: k2av.guy at gmail.com (Guy Olinger K2AV) Date: Fri, 19 Feb 2016 15:30:19 -0500 Subject: [Elecraft] KPA1500 In-Reply-To: <56C72E37.8020909@montac.com> References: <1455817083878-7614288.post@n2.nabble.com> <07433BA3-3823-4230-B367-D9A0A5DDB595@woh.rr.com> <56c67088.8e59620a.3716f.ffffd445@mx.google.com> <56C67E0C.8030900@montac.com> <56C6803D.7060404@gmail.com> <1455871555886-7614313.post@n2.nabble.com> <56C6E90F.7060804@gmail.com> <56C72E37.8020909@montac.com> Message-ID: Lots of possible reasons why Elecraft might not do a 1500, but specifically price breaks and unwillingness to adopt a product that from other manufacturers has proven problematic at our price range for well understood reasons. Elecraft has been conservative about introductions, and that plays well for what they *do* produce. Ignore the boo-bird gallery on this reflector and note long term performance of other ham manufacturers including near death brushes or full on encounters with bankruptcy. Elecraft *grew* their business during the great recession. Financially stable and responsive to customers with great products. Hard to find combo, generally. Personally I'll let 'em do whatever they want (as if I could really affect that). They *might* put out a 1500, which I would buy in a heartbeat for the integration. But it wouldn't be a hacksaw job and it wouldn't put their balance sheet near the edge, and it *would* have gotten past all those issues that 1500's seem to be dogged with. 73, Guy On Friday, February 19, 2016, Clay Autery wrote: > Shhhhh...

When set at 100W output, I am getting the following approximate output values: 10m ~55w 12m ~40w 15m ~50w 17m ~60w 20m ~60w 40m ~70w 80m ~70w 160m ~70w My testing methodology involved connecting the short (~12") coax out of ANT1 to an HF power meter's input. I then connected the power meter's output to a 300w dummy load. I then tuned to the band to test, put the rig in CW mode, and keyed down for a few seconds. The power meter is set to read peak output, not average output. As a self-check, I would randomly run the test using AFSK-A RTTY, just as a double-check to ensure I was getting 100% duty cycle. The results are the same. After discovering these power output values, I ran the TX Gain Calibration via the K3 utility. It ran through the 5w and 50w calibration tests successfully. After running the TX Gain Calibration, my output power readings didn't change significantly. My readings then are: 10m ~50w 12m ~60w 15m ~50w 17m ~60w 20m ~60w 40m ~70w 80m ~70w 160m ~70w Is there something else I should check before I plan a call back to the Elecraft mother ship next week? If it needs to go home for repair and testing, it will have to wait until after the Georgia QSO Party the second weekend in April. I'm getting good signal reports when I'm on the air, but it seems odd to me that, with the rig set for 100w out, and in a full duty cycle mode, I'm only getting 50%-70% of my rated power.

I have tried to solve the problem when using TrueTTY and K3s APF. Everything works fine without APF (using rev data) but if I turn APF on I lose all the tracks on the waterfall. I have tried all mark and shift combination. APF works ok with MMTTY but it is too clumsy program for me so that's why I want to use TrueTTY. MMTTY use LSB and Truetty use USB. I have tried to turn TrueTTY to reverse (LSB) no luck.

Reason I ask is I now have 3 10W rigs (K3, K3S and a K2) and may be building a 4th soon (another K2/10). And in the very rare event when do go QRO, it would probably be cheaper to just get one 100W amp to use with them all than 4 100W amp modules for each. So my idea is a KXPA100 for my QRO ops with each one. So just curious how well this amp works with the K3 and K3S? I would imagine it'd be similar to using it with the K2 or ?

If you want an SSPA that will do 1.5K spend the $8K for the SPE 2KFA. If you think Elecraft can produce an amp of that caliber for less than $8K I've got some lakefront property for sale. There simply aren't enough hams ready, willing and able to spend that kind of money to make it economically viable. They'll get killed by the amp competition. As soon as all the fan boys with money are exhausted the market will dry up. $8K+ for an Elecraft SSPA or less than half that for an Ameritron AL-1500...and before you go down the "Ameritron is crap" road... a bunch of real famous contesters use the AL-1500 and win with it.

The spring-loaded solder sucker worked FB for me, used just as Kevin describes. On a couple of occasions I had to do it from both sides of the board to get everything clean. I also found it the case that shouting a familiar four-letter expletive immediately upon realizing that the error had been made was strongly associated with success in doing the fix. There is no theoretical reason why that should be so, but the correlation is empirically perfect.

That's not to say I didn't make mistakes :D. I did, however, take some advice to heart when assembling it (I believe it came from the website or the manual), in that for a section, I would add all the components, bending their leads to stay in place and then come back to solder after checking things again. As to whether this helped prevent mistakes, I can't really say for certain, but I will say I was lucky enough to not experience many issues with my build. Anyway, I digress... I was lucky enough at the time to inherit a Pace desoldering unit (a MBT-100 in fact) that came from the old circuits course at the local college. For through-hole type projects, those things are a godsend. I still have it too, having just replaced the handset along with acquiring a handful of new tips. If you have it in the budget (and plan on doing more kits), I highly recommend keeping an eye out for one. They're discontinued now from Pace, but there's still plenty out there with lots of life left in them and parts are available if you look. That said, I think I used that thing more than not as my "skill" with wick has only really come to fruition in recent times.

You don't know what it would cost them to produce the amp. My speculation is that they could do a better job than SPE -- if they chose to do it. How many would they sell? Who knows? The ham population is growing older fast and a lot of us old codgers can "afford" a new amp of that caliber. I have nothing against Ameritron amps...happen to own one myself...in addition to three Alphas and the KPA500 -- so no I don't "need" a KPA1500. But I would buy one just because I know the integration with the K3 and quality that would go into it would be fantastic -- not to mention that it would be from an American manufacturer with the best service in the industry. Furthermore, Elecraft is competing quite successfully against competition so I disagree that they would be "killed" by the amp competition. Alpha used to be the "Cadillac" but the company has deteriorated significantly. Acom and OM Power represent competition but neither one has a full bore solid state 1500 watt amp with headroom...Ameritron is OK but not the same craftsmanship or quality of Elecraft. My original question to Wayne or Eric was how many people putting money down would it take for Elecraft to produce such an amp. It's strictly a business decision that only they can make.

Surrender is not an option. Then I remember a trick I've known since my first encounter with PCs and solder wick. Reflow the joint with fresh solder. Wick that away. It usually leaves a nice clean hole. Sometimes, I reflow the joint more than once being careful not to overheat the area. If it isn't clean enough to insert the new component, use a stainless steel needle to gently poke through the hole. Don't forget there may be a delicate via that will come out with too much force. I use an upholstery needle that is about 10" long. It keeps your fingers out of the way so you can see what you're doing. And it doesn't get lost on the bench as easily as small needles. To aid that, I slipped a piece of flourescent lime parachute cord over the non-business end to make it look more like a tool with a handle.

When you are faced with that necessity, remember that the most valuable part is the board - avoid damage to the board at all costs. Elecraft boards are constructed with thru-plated holes, so be careful that the solder pad on both sides of the board is preserved - DO NOT drill out the holes. Those thru-plated holes are often used not only to solder the component lead, but also to continue the circuit from one side of the board to the other, so preserving the thru-plated hole and solder pads is important. If you do not have de-soldering tools to accomplish the task, or you have tried what you have and it was not successful, forget about salvaging the part. New parts are inexpensive compared with the investment in the board and the other mounted parts. *Sacrifice* the part. For two (and sometimes 3) lead components, you can heat each lead alternately while slowly working the part out of the holes in the board. For multi-legged critters, use flush cutters and clip the lead as close to the body as possible, then heat each of the remaining leads and remove them one at a time. For relays and other parts that cover the leads on the component side, use pliers or whatever tool works and crush the body of the component so you can remove the leads one at a time. Once you have removed the leads, clean up the remaining solder with solder wick. If additional solder remains in the hole, use a wooden toothpick (or a stainless steel needle), heat the solder pad and push the remaining solder out of the hole - task accomplished. Even though I have a Hakko 808 which is usually successful for removing the solder and the part intact, there are times I resort the destroying the part and cleaning up the holes with a stainless steel probe that I keep handy. 73, Don W3FPR On 2/20/2016 10:11 AM, Mark Petrovic wrote: > I'm assembling an Elecraft K1, and get the distinct feeling that > unsoldering really is the last thing you want to be involved in.

I don't use it on SMD components that have a small number of leads. Those with 2 leads, I heat the leads alternately until the component has absorbed enough heat to allow it to literally float off the pads. Those components with leads formed so I can get a *very* thin knife blade tip under the lead, I can start at one end and heat the pad until the tip of my knife can lift the lead off the pad. Note that I have sharpened my pocket knife for many years and the blade has a tip which is more slender than the most narrow Exacto knife. If those techniques will not work, I use Chip-Quik. The only downside to Chip-Quik is that *all* the Chip-Quik residue and special flux must be cleaned up or the new solder will not stick. 73, Don W3FPR On 2/20/2016 12:50 PM, Wayne Burdick wrote: > I really should update the Desoldering Primer to mention Chip-Quik.

They all have advantages and drawbacks. Acom and SPE both build to a high standard and in my experience are most reliable. The Acom 1000 is perhaps the very best buy in a non-automatic self tune vacuum tube amp. The Acom 2000A is a beautiful auto-tune and runs quietly but waiting for it to warm up takes a long time! The SPE Expert 2KFA is solid state and instant on. It is a great except for two things: 1)This is a very noisy amplifier and I wonder if this is not a problem with most solid state amps. Cooling is critical to keep junction temperatures down. The noise problem remains even if running on the 600 Watt power level at the 400 Watts allowed in EI for non contest QSOs. I can not operate with the SPE unless wearing headphones preferably ones with good noise rejection. 2) If one runs the SPE 2kFA without the built in automatic ATU then even with an SWR of around 1.5/1.6 you will create terrible distortion on either SSB or CW. This distortion will quickly make you unpopular on the bands. One must be careful of this. Dropping the power level does not seem to solve this problem. Of course it has a good internal automatic tuner which works wonderfully so if you use the tuner there is no problem. A multiband antenna which did not require a tuner normally but did on one band could prove slightly problematic. You would need to change it over to another of the six antenna output connectors and use the built in auto-tuner. I must say something else in favour of the SPE it does not excessively heat the room while having the Acom 2000A in use is like having Wayne's daughter's electric heater on. The SPE is definitely more efficient when it comes to power consumption. I am an almost fanatical Elecraft user but do not own a KPA500 as I saw no point. A KPA 1500 would certainly interest me but I wonder if it would not be priced at too high a level for my pocket. Alphas do not appear to be overpriced but these days have a poor reputation in Europe. This surprises me but is the case. I have at times seriously considered Alpha and backed off because of the advice of friends whose opinion I value. Ameritron amps also get bad press but seem to do the job for relatively little money. I have a friend with an old Ameritron who is still very fond of it and would not part even though he now also owns an Acom 1010. So the lower cost alternative continues to fill a need. My friends with KPA 500 amplifiers are all fond of them and have nothing negative to say though I am told on air by some others that the KPA 500 is not so quiet. However the EI Elecraft guru EI6IZ says that the KPA 500 is quiet. Not having used one I can not say. No one seems to be selling their KPA 500. Some of us really want it to be as quiet as a library. Before you purchase an amplifier try using one of visit a ham with one. Consider noise, turn on time, distortion, reliability, band coverage, power efficiency and your pocket book. If you are an old goat like me with a fragile back think of weight as well. The KPA 1300 looks good for DXpeditions as of course does the KPA 500 which has been so popular of late. Elecraft is first class in all respects. Design, service and support are just unbeatable. We are fortunate that they exist and have brought higher standards to our hobby. I suppose a KPA 1500 would have me drooling. 73 Doug EI2CN -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of john at kk9a.com Sent: 20 February 2016 18:02 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KPA1500 It would likely cost over $10,000 like the Ohio based Dishtronix Prometheus and I do hear of many stations using them.

I particular I would suggest looking at the LDMOS amp kits and assembled amps recently available (e.g. W6PQL) http://www.w6pql.com/1_kw_sspa_for_1_8-54_mhz.htm I have built some of his 2m amp and his 23cm amp kits. Really have to wonder where the ham "build-it" spirit has gone? But Jim will build on contract if you got the money (which apparently there are quite few that do). Maybe someday I will have Jim build the amp pallets for me to incorporate into a full amp of my own design. He really offers a lot of subassemblies which one can combine. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From kl7uw at acsalaska.net Sat Feb 20 14:37:19 2016 From: kl7uw at acsalaska.net (Edward R Cole) Date: Sat, 20 Feb 2016 10:37:19 -0900 Subject: [Elecraft] Unsoldering Message-ID: <201602201937.u1KJbKtb020832@mail40c28.carrierzone.com> Mark, I have not built a K1 so do not know how it is designed. If you are wanting to remove surface-mount components the simple method is to first wick excess solder away and then use two solder irons on either end of the device to unsolder and lift the component. If this thru-hole construction then resistors and capacitors should not be too difficult to unsolder each lead at a time. Removing leaded transistors can be tough. Sometimes one has to just clip the leads and remove the transistor and then remove each lead remnant individually with a solder iron. The transistor is usually junk if you do that. A solder-sucker is handy with small leaded devices. High power transistors with large metal "ears" can be a challenge. One needs a high power solder iron with large tip. Heat and remove solder with wick then use knife edge to lift a lead while heating with solder iron. Once enough is lifted a flat screwdriver can help lift the rest. Caution that applying heat too long can cause high power transistor failure. All this is a good reason to double-check installation in the first place. But have been there and done it. 73, Ed - KL7UW From: Mark Petrovic To: elecraft at qth.net Subject: [Elecraft] Unsoldering I'm assembling an Elecraft K1, and get the distinct feeling that unsoldering really is the last thing you want to be involved in. I have solder wick that has embedded flux, and I have a solder sucker that seems huge compared to the size of the features I'm dealing with. The wick works ok at getting some of the solder out, but not all of it. And a little bit of residual solder is still a major physical blocker to correcting a misplaced component or bad joint. I feel like I'm a pretty good solder-er, but I have not had good luck with unsoldering. Is it just me or does everyone have this problem? Thanks.

My antenna will be an inverted V at 30', and I'd like recommendations for a battery technology and brand, assuming I don't use the internal batteries (I think I would rather not). I'm looking for something that will work with a KX3 as well as an IC-706 MKIIG. Ideally, I'd like to get several hours out of it if possible, but I do know that that's hard to say based on number of contacts and SSB/CW. What's the best method of making a connection from said batteries to the KX3? I suppose powerpoles to the standard KX3 connector would be idieal.... Anyway, thanks so much!

It is less than reassuring not to be able to see exactly what the connectors are doing, but it does work - as you found out. To your comment, if you have Rev H of the manual, that step is immediately before Figure 47 on page 43. Figure 47 it identifies the length of the cable as 5" (13 cm) for the J5->J82 cable and 10" (25 cm) for the J84 -> J85 cable. So that 5" cable was originally scheduled for the J5->J82 run. The left over cable should have been the 12" (30 cm) cable that would run between J92 and the KAT3 ATU. It was installed as described on pages 28 and 19 "Installing the Auxiliary KRX3A Antenna Input via the KAT3A". Yes, the current firmware (5.38) displays KRX3 instead of KRX3A. I thought that was being changed, but apparently not. I'll make a note of that in the manual for others. Thanks for noting it. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bob Novas Sent: Saturday, February 20, 2016 1:16 PM To: elecraft at mailman.qth.net Subject: [Elecraft] KRx3a Install Today I installed a KRX3A in a K3S. Not my favorite day. On the plus side, I plugged the K3S in and everything seems to be working. Big grin! On the negative side. 1. I do not believe there is anywhere described installing the TMP cable between KREF3 J5 and KRX3A J82, other than in Figure 47. I didn't know which length TMP cable to use, so I used a 10" one. 2. I have a 5" TMP cable left over (I chose to go the Aux Antenna BNC Connector route). Is this expected? 3. I hate the way the KRX3A has to be blindly inserted onto the input/output connectors. I guess I got it right. 4. The config menu says that a KRX3 is installed (not a KRX3A). Is that ok? (latest firmware all around). All in all, a harrowing 4 hour experience I don't want to repeat.

I did a rough and fast add up of all the stuff needed to build one of his 1KW designs using assembled and tested boards. I came up with right at $2K. That's just parts. No sheet metal, no fasteners, no wire, no fans, NO 50V - 40A switching power supply. You won't be running it on 120V and it won't fit in a K3 case. The LPF he uses could be improved. He uses a 5 pole Chebishev with SMT Mica caps. I'd use the 5 pole Cauer from the SSPA project in the 2012 Handbook, sized for 1.5KW. It uses ceramic SMT caps (more expensive but worth it for a clean amp). Using the Cauer design means tuning the LPF with a network analyzer to place the nulls on top of the odd order harmonics. Someone has commissioned Jim to build a 2KW version of his 160-6m SSPA. Basically two of his 1KW amps throttled back to 750W, in one box with a high power splitter/combiner. The power supply jumps to 50V, 60A and it still won't fit in a K3 case. The two 10"x10"x4" aluminum heat sinks weigh 10 pounds combined. It will not be a quiet amp but might actually do full power RTTY all day.

The real question is just how soon can a technician get to a particular repair. I work on the legacy gear for Elecraft (K2, K1, KX1, XV series transverters) and the total turnaround time depends on how much backlog I have stacked up. I do all work on a first in, first out basis depending on when the radio arrives here. My personal backlog varies from 1 week to 3 weeks. The work queue at Elecraft for the K3/K3S, KX3 is similar, and I believe is handled in the same way - first in, first out. The RSA forms currently being issued by Elecraft state a 3 week turnaround time. In some cases, it can be shorter, but normally not longer that that 3 weeks unless highly unusual situations exist. 73, Don W3FPR On 2/20/2016 8:56 PM, Bruce Osterberg wrote: > Hello: Curious about the turn around time for a K3 sent into Elecraft > for Repair?

The problem, I gather, is that with a small radius turn the inner conductor can migrate through the dialectric. I filed the point away but didn?t think much about it at the time since I don?t (as of this moment) use coax chokes. But today, as I was doing some tidying up of the rat?s nest of cables behind my desk?s misleadingly neat fa?ade, I noticed something. The coax ? RG8 ? connecting the KPA500 to the KAT500 sitting atop takes a very sharp bend. The same is true of the cable coming out of the K3, making a sharp right turn, travelling under the desk and then making another sharp turn to connect to the amp. The same is true of the K2 and its tuner on which it is perched ? a short, sharp turn. I am going to guess that any change to the characteristic impedence, if the center conductors in the interconnects do migrate, would not itself be a problem over very short lengths. But the possibility of a dialectric breakdown caused by a severe migration is more troubling. So a question for those who know about such things: In the zeal for tidyness and the shortest possible cables, is there a significant risk? How fast does migration occur ? should these sharp-U-turn interconnecting cables be replaced on some regular basis?

The problem, I gather, is that with a small radius turn the inner conductor can migrate through the dialectric. I filed the point away but didn?t think much about it at the time since I don?t (as of this moment) use coax chokes. But today, as I was doing some tidying up of the rat?s nest of cables behind my desk?s misleadingly neat fa?ade, I noticed something. The coax ? RG8 ? connecting the KPA500 to the KAT500 sitting atop takes a very sharp bend. The same is true of the cable coming out of the K3, making a sharp right turn, travelling under the desk and then making another sharp turn to connect to the amp. The same is true of the K2 and its tuner on which it is perched ? a short, sharp turn. I am going to guess that any change to the characteristic impedence, if the center conductors in the interconnects do migrate, would not itself be a problem over very short lengths. But the possibility of a dialectric breakdown caused by a severe migration is more troubling. So a question for those who know about such things: In the zeal for tidyness and the shortest possible cables, is there a significant risk? How fast does migration occur ? should these sharp-U-turn interconnecting cables be replaced on some regular basis?

Those 'jumpers' are usually only a few feet long. Once you exit the station, you will likely have longer coax runs to the antenna where the larger coax makes sense. The coax cable loss is proportional to the length and the inherent loss of the connecting cables. Smaller and short coax cables will have insignificant loss at HF. Smaller coax diameters will have smaller bending radius requirements than larger coax. 73, Don W3FPR On 2/20/2016 9:34 PM, Dauer, Edward wrote: > A week or two ago there was a thread here on the permissible bending radius of various types of coax, occasioned by a discussion of ?ugly balun? chokes.

Seriously, desoldering is not easy and not easily learned even if you have a good teacher. Two people trained alike will not do it alike. It takes lots of patience in personal self-taught learning. Patience is also the key word in the actual removal process. I think women are better at it because they don't lose patience and resort to brute force. The best paid person on the production line will be the rework specialist because they earn every penny. You have already been given much good advice. The only thing I would add is to buy some junk boards at surplus or flea market and practice before you try the expensive boards. 73, Fred, AE6QL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Mark Petrovic Sent: Saturday, February 20, 2016 7:12 AM To: elecraft at qth.net Subject: [Elecraft] Unsoldering I'm assembling an Elecraft K1, and get the distinct feeling that unsoldering really is the last thing you want to be involved in.

A simple RF sense ckt would be 1pF coupling cap from the coax line (maybe use a coax tee and connect the RF sense box to the tee). At HF the tee will not show significant impedance bump. The cap feeds a diode like the BAS-16 followed by bypass caps to ground (0.01uF and 10uF ought to suffice). This feeds thru a 1K resistor to control a NPN transistor that will key the amplifier to ground. You might add a 1uH choke in line before the resistor if concerned that the RF is not completely smoothed to dc. The circuit I described is used in the W6PQL 2m 80w amplifier for RF sensed PTT (except different values for bypassing 2m). http://www.w6pql.com/2_meter_80w_all_mode_amplifier.htm Another way is to buy a kit. W6PQL sells an ALC detector board which passes RF thru and detects RF providing a negative voltage. The kit includes 750-ohm resistor which is good for 1-2w. Probably better to use a 2K resistor for 10w. I am using this board kit with 10K resistor to sample 2m 80w RF for a RF output meter. http://www.w6pql.com/Sampling_RF_Power.htm#alc Let me also comment about using the KXPA-100 with either K3/10 or KX3. I recently bought a KXPA-100 for just those two radios and its a perfect companion. One plus is heat is kept out of either radio which reduces frequency drift when running digital modes. Of course digital modes don't need 100w but you can reduce drive to 20w with either radio driving the KXPA-100. I don't plan to use my K3 outside the shack but the KX3 may go mobile with the KXPA-100. I incorporated a PTT switch in my new station control panel to select either K3 or KX3 PTT which is provided to several accessories including the KXPA-100. 73, Ed - KL7UW From: Brendon Whateley Cc: Elecraft Reflector Reflector Subject: Re: [Elecraft] K3/K3S 10W models with KXPA100 Message-ID: Content-Type: text/plain; charset=UTF-8 Ron, Would it be possible to put some sort of RF detector between the rig and the amp to trigger the KEY line?

Unless you have a time-reversal device, the amp won't switch until RF is already flowing. Maybe it wouldn't damage the amplifier in this case, but it would certainly mess up the shaping of CW elements. Much better to add an amp key circuit to the transceiver if it doesn't have one. If done correctly (like the N0SS circuit for the K2 that was mentioned), the amp key line is activated a few ms before RF is produced.

Current Draw per meter in K3 was 1.05A. Well Since I had two Boards, I figured I would swap them, so I changed position of the two KSYN3A SYNTHESIZER boards, reconnected the cables. Main Receiver is now dead with only white noise. Sub receiver dead also as before. I pushed the DISP Button and noticed that the current draw was now 1.4 amps, and the KYS1 and KYS2 were gone! No indication they were installed. Put boards back to original position, main receiver working OK, Sub receiver still nothing. when DISP button Pushed KYS1 and KYS2 showed up again as OK, and current draw back to 1.05 Amps. I believe the Auxiliary KSYN3A SYNTHESIZER board is bad. I could test further and set the K3 back up as a single Transceiver with no Sub. But that would mean taking out the Sub, Installing a Jumper on the input connector for the Sub and removing one of the Synthesizer boards and setting the K3 up as a single KSYN3A SYNTHESIZER as per figure 12 on Page 15 of the KSYN3A SYNTHESIZER Manual.

I modified Tim's Python scripts to work correctly under Windows and perform the same action in SSB mode. Though, if the serial port is changed as noted, it should work under Linux as well. I have included two versions of each, one "win" version and the other "linux", the difference only being the CR/LF encoding of the file. I modified a few of the commands to suit my preferences and had to fix a slight issue where multiple commands didn't execute reliably when combined in the same statement. (the whole reason for running it in a loop in python was to add a delay!) It doesn't quite put the DX station on the left "margin" of the P3, but is close enough and gives you a peek of what is just below the DX. It runs slow due to the one second delay between commands, however it works pretty well otherwise. I have included a modified reset script as well. If in the future, a NOP (No Operation) or delay macro is discovered in the K3 that could be used to allow proper pacing, the python script can be retired. I have posted them on Dropbox here: https://dl.dropboxusercontent.com/u/24789865/Elecraft-K3-Pan-Pile-Up-SSB.zip Warren Merkel, KD4Z The new SSB version script looks like this: import serial import time # Original script : Tim Seed # Modified: Warren Merkel, KD4Z # modified for SSB mode and split commands into single steps for robustness # Used to configure the K3 and P3 to shift the display so that a DX station # currently tuned in VFO A, is moved to the left side of the P3 screen, # and the P3 span and tracking modes set to allow easy VFO A movement # without causing the P3 to shift the position of the DX station # from the left side. # Note, you likely have already set the K3 into Split mode before executing # this script, so that isn't handled here # Requires Python 2.7 or 3.x and appropriate PySerial library # #FXT - Fixed or Tracking Select # options are: # FXT0; Tracking # FXT1; Fixed-tune (used below) # #FXA - Fixed-tune Auto-adjust mode (screen pan method) # options are: # #FXA0; Full screen # #FXA1; Half screen (used below) # #FXA2; Slide # #FXA3; Static # SPN - Display Span size # options are dependent on size desired, xxxxxxx in 100 Hz units # for example: # #SPN000500; sets to 50 kHz # #SPN002000; sets to 200 kHz (used below) # DN - Move VFO A Down # UP - Move VFO A Up # the options are in fixed values.

Why would you want to log 'NN' as 100? 'NN' is probably the original cut number (5NN) and I don't remember seeing any indications of rounding up (i.e., 99 to 100) any numbers. Doubt you would consider copying 5NN as 5100. Just curious. Mike / W8DN On 2/21/2016 4:15 PM, Chester Alderman wrote: > OK...but what if you receive 'NN'?

Not just for kit building. Just for fooling around with various ideas on a circuit board where you much more prone to making mistakes. Having one of these tools gives me a much greater sense of confidence. I can solder in an entire 16 pin IC backwards and get back out in minutes. Not that you should allow this to be an excuse to be less careful. But accidents happen. Especially when your eyes are getting older and components are getting smaller. Circuit Specialists has several other desoldering tools. If the price is within your budget, it's a great tools to have. 73, Doug -- K0DXV On 2/20/2016 8:16 AM, Chip Stratton wrote: > Using solder wicks and cheap solder suckers is tough.

Naturally many early Hams were old railroad men and the single long dash instead of five dashes for zero became common very quickly on the bands even before the spark gaps were silenced. When keyers and keyboards came along it was no longer possible for people using them to send the American Morse zero so "T" was substituted. Another adaption of Railroad Morse that makes a good bar challenge is to ask why Hams send "es" for "and". Dit, dit-dit-dit is Railroad Morse for an ampersand.

Of course, I agree with you that using a simple RF sensed PTT is hard on amplifier and TR switch. My reply was to a question how to build an RF sense ckt and not how to design one into an existing amplifier. One usually finds these on VHF amps designed for FM. I suppose they just suffer hot switching for the price they get. In the cited W6PQL 2m amp, he actually addresses this by adding a bias delay ckt so the amp does not pass RF until TR relay has switched. I suppose one could duplicate that, but if done on a KXPA-100 it would likely void any warranty. Way better to use external PTT which is provided for the KXPA-100. The K3/10 has min 8ms delayed RF upon PTT to provide proper sequence of operations. I suppose the KX3 has a similar delay keying ckt. How this affects QSK operation is beyond scope of the original question - which is all I answered. But good that you pointed out the hazard of simply adding RF sensed PTT. 73, Ed - KL7UW ----------------------- From: Vic Rosenthal To: Edward R Cole Cc: Elecraft at mailman.qth.net Subject: Re: [Elecraft] K3/K3S 10W models with KXPA100 Message-ID: Content-Type: text/plain; charset=us-ascii I don't like circuits like this because they guarantee hot-switching of the amplifier. Unless you have a time-reversal device, the amp won't switch until RF is already flowing. Maybe it wouldn't damage the amplifier in this case, but it would certainly mess up the shaping of CW elements. Much better to add an amp key circuit to the transceiver if it doesn't have one. If done correctly (like the N0SS circuit for the K2 that was mentioned), the amp key line is activated a few ms before RF is produced.

Presuming that both of you have the internal tuner in your K3s and no external tuner, then, yes, what you're seeing is expected and normal. Remember that the internal tuner provides a match to the receiver and transmitter but cannot change the complex impedance that is present on the feed line. I do have an external tuner and the TXMON sampling unit is connected between it and the amplifier. I also have an internal tuner on the K3 and sometimes use it instead of the external tuner. When I do, the P3 SWR meter is predictably reading much higher than the radio's SWR meter. 73, Nate N0NB -- "The optimist proclaims that we live in the best of all possible worlds.

It's FB all the way above 1 KW as long as it's not subjected to very high SWR's at high power. (Actually RG-58 can handle 2 or 3 KW at an SWR of 1:1). Power handling is only one property of coax. Another is SHIELDING, and one measure of shielding is the Transfer Impedance, which is the ratio of the voltage between center and shield as a result of shield current. The lower the transfer impedance, the better the shielding. Transfer impedance is the result of shield quality -- density and uniformity -- and its resistance at the frequency of interest. The lower limit on transfer impedance is the RESISTANCE, so a shield with lower resistance will provide better shielding. Since shield resistance is largely a function of skin effect, larger diameter coax generally provides better shielding than a smaller one. THAT'S why all the coax in my station is RG8, specifically Davis Buryflex. What's the big deal about shielding? Well, for several years, I've been working on my station to minimize issues with harmonics when I'm running SO2R on harmonically related bands. I have very good bandpass filters, and I've added double stub networks to kill harmonics on several bands. But I wasn't getting as much suppression as I expected (and measured on the networks on the bench), so I suspected issues with coax. Last summer, I replaced all the inside cable with hand-soldered Amphenol 83-1SP connectors on cables cut to length. The result was an improvement of about 10 dB in harmonic suppression! The lesson -- when you're looking more than about 50 dB down, little stuff really matters. 73, Jim K9YC From aldermant at windstream.net Mon Feb 22 00:00:27 2016 From: aldermant at windstream.net (Chester Alderman) Date: Mon, 22 Feb 2016 00:00:27 -0500 Subject: [Elecraft] OT: CW Contest logging question In-Reply-To: <56CA36CF.3060000@roadrunner.com> References: <000001d16cec$feb743c0$fc25cb40$@windstream.net> <56CA36CF.3060000@roadrunner.com> Message-ID: <000001d16d2d$f29fcd50$d7df67f0$@windstream.net> Thanks Mike.

I received a number of different constructions for the power exchange in ARRL DX, and I just used common sense to determine what I entered in the log. NN is 99, 1K, K, KW and such got entered as is. The low power ops were a treat. I got a lot of 5 and 1 reports for power, some would try to lessen confusion and sent 5W or 1W. I entered those in the log as received. I had one exchange with a (very weak) station who sent 1M. Maybe a milliwatt? Who knows? I put it in the log as I received it, hopefully it will go through OK. As long as he puts that in his log as the data sent, I would think it shouldn?t be a problem. 73, John K8AJS bastinj at gmail.com From n4zr at contesting.com Mon Feb 22 08:50:15 2016 From: n4zr at contesting.com (Pete Smith N4ZR) Date: Mon, 22 Feb 2016 08:50:15 -0500 Subject: [Elecraft] OT: CW Contest logging question In-Reply-To: <56CAA485.4050409@audiosystemsgroup.com> References: <000001d16cec$feb743c0$fc25cb40$@windstream.net> <56CA36CF.3060000@roadrunner.com> <000001d16d2d$f29fcd50$d7df67f0$@windstream.net> <56CAA485.4050409@audiosystemsgroup.com> Message-ID: <56CB1217.6090102@contesting.com> Can this thread please go back to CQ-Contest where it (unfortunately) belongs? 73, Pete N4ZR Download the new N1MM Logger+ at .

When set at 100W output, I am getting the following approximate output values: 10m ~55w 12m ~40w 15m ~50w 17m ~60w 20m ~60w 40m ~70w 80m ~70w 160m ~70w My testing methodology involved connecting the short (~12") coax out of ANT1 to an HF power meter's input. I then connected the power meter's output to a 300w dummy load. I then tuned to the band to test, put the rig in CW mode, and keyed down for a few seconds. The power meter is set to read peak output, not average output. As a self-check, I would randomly run the test using AFSK-A RTTY, just as a double-check to ensure I was getting 100% duty cycle. The results are the same. After discovering these power output values, I ran the TX Gain Calibration via the K3 utility. It ran through the 5w and 50w calibration tests successfully. After running the TX Gain Calibration, my output power readings didn't change significantly. My readings then are: 10m ~50w 12m ~60w 15m ~50w 17m ~60w 20m ~60w 40m ~70w 80m ~70w 160m ~70w Is there something else I should check before I plan a call back to the Elecraft mother ship next week? If it needs to go home for repair and testing, it will have to wait until after the Georgia QSO Party the second weekend in April. I'm getting good signal reports when I'm on the air, but it seems odd to me that, with the rig set for 100w out, and in a full duty cycle mode, I'm only getting 50%-70% of my rated power.

Well, The Plato Zero/TechSpray Unfluxed - (now is labeled as Unfluxed desoldering braid) is dedicated for applications where water-soluble (water-based) flux has been used. It is no-flux coated wick. The Plato/TechSpray No-Clean - (now is labeled as No-Clean desoldered braid) is dedicated for all applications where No-Clean flux has been used for soldering the parts. It is No-Clean flux coated wick. Usage of this wick will not leave ionic residues.

Out of curiosity, I turned it on, wrapped wire around it and connected it to the antenna terminal on my KX3. It was just enough antenna to bring WWV in weakly on 10 MHz and the noise background was just perceptibly higher than with no wire attached to the antenna term. It still didn't register on the S-meter. Pressing keys did not produce a rise in background noise on any band from 160-6 meters. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of GRANT YOUNGMAN Sent: Sunday, February 21, 2016 9:12 PM To: elecraft Subject: [Elecraft] Keyboard RF Interference Can anyone suggest a COMPACT keyboard used with a KX3/PX3 in a ?near antenna? portable environment that you have found to be clean of RF hash? I purchased a small USB keyboard (Gearhead, from Fry?s), and its matrix scanner is generating tons of RF garbage ? spreading noise spikes at around 8 kHz intervals all over 40/20M. It?s coming from the keyboard itself. Ferrites on the USB cord have no discernible impact on the garbage. Touching the metal bottom plate significantly increases the level of the noise. When portable I?m generally only 5-15? from the antenna (a Buddipole). At least the keyboard was cheap enough to be a non-painful throwaway. Thanks ?

I inherited some "previously driven" (aka used) coax from work thinking to save money -ha! It dates from before I began working at my last employer as comm tech else would never have been purchased. I found in preparing for installing connectors the shield density so poor one could not make good connections -- only useful buried in ground as radial. I ran into the coax shield quality issue in a different situation but is the same isolation or "radiation" problem. When I increased power from 600w to 1400w on 2m eme I suddenly started blowing preamps. There were multiple "suspects": My TR relays were not rated for 1200w nor had the Rx port isolation needed. I try to keep RF into the preamp < 0 dBm (1mw) and 1200w = +61 dBm. My relays were only spec at 45-dB isolation. Also turned out only good to 800w. I replaced all after melting down three of them!! Now using NARDA sem123N rated 1200w & 80 dB isolation. But to the point the high emf of being installed at the antenna subjects connecting coax jumpers to high RF fields so shielding is critical. I was using RG-58. I swapped for RG-142 double-shielded coax. I also fed 12v to the preamp thru shielded power wiring (RG-6 or RG-58). Preamps has feedthru bypass caps so that path should not as critical. So changing three things means I do not know which was the "cure" but no longer blow up preamps. Double-shielded coax is commonly used as jumpers with repeater duplexers for the same reason cited by Jim. I wonder if better coax jumper in the shack would improve isolation from wifi type RFI? Probably couldn't hurt. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From PKA at telepost.gl Mon Feb 22 13:49:16 2016 From: PKA at telepost.gl (=?iso-8859-1?Q?Poul_Erik_Karlsh=F8j_=28PKA=29?=) Date: Mon, 22 Feb 2016 18:49:16 +0000 Subject: [Elecraft] QSLS from VP8STI and VP8SGI In-Reply-To: References: Message-ID: <52CDCAF0-B910-48E8-87F8-7C724B99C1D5@telepost.gl> Nice for u, but why did u post it on Elecraft site?

When set at 100W output, I am getting the following approximate output values: 10m? ? ~55w 12m? ? ~40w 15m? ? ~50w 17m? ? ~60w 20m? ? ~60w 40m? ? ~70w 80m? ? ~70w 160m? ? ~70w My testing methodology involved connecting the short (~12") coax out of ANT1 to an HF power meter's input. I then connected the power meter's output to a 300w dummy load. I then tuned to the band to test, put the rig in CW mode, and keyed down for a few seconds. The power meter is set to read peak output, not average output. As a self-check, I would randomly run the test using AFSK-A RTTY, just as a double-check to ensure I was getting 100% duty cycle. The results are the same. After discovering these power output values, I ran the TX Gain Calibration via the K3 utility. It ran through the 5w and 50w calibration tests successfully. After running the TX Gain Calibration, my output power readings didn't change significantly. My readings then are: 10m? ? ~50w 12m? ? ~60w 15m? ? ~50w 17m? ? ~60w 20m? ? ~60w 40m? ? ~70w 80m? ? ~70w 160m? ? ~70w Is there something else I should check before I plan a call back to the Elecraft mother ship next week? If it needs to go home for repair and testing, it will have to wait until after the Georgia QSO Party the second weekend in April. I'm getting good signal reports when I'm on the air, but it seems odd to me that, with the rig set for 100w out, and in a full duty cycle mode, I'm only getting 50%-70% of my rated power.

That requires you to do the TX Gain Calibration (see 5.14 Release Notes). K3 Utility makes the task easy - just connect a dummy load that is good for 1.8 to 54 MHz and capable of 50 watts or greater and the process is automatic - follow the prompts in K3 Utility, it will take only about 2 minutes to complete after the dummy load is in place. If K3 Utility fails the TX Gain, there is one more chance - do each band manually (see the Calibration part of the manual). If that does not correct it, contact support. 73, Don W3FPR On 2/22/2016 11:21 AM, Ian Kahn wrote: > Reposting, since this didn't seem to get out when I originally sent it last > Friday evening.

I suspect that the K3 Transverter ports reflect the same frequency limits as programmed into the radio as the main antenna port. The K3 is apparently software transmit ham band limited as far as I have read. It can be unlocked for "MARS" use, and that apparently gives general coverage transmit except around the IF and certain restrictions on power on the 27 MHz band. I don't have a K3 yet, I am thinking about one, but am also considering all other options. The KX3 with PX3 that I have performs exceptionally well on receive with my VHF transverter, but the transmit wideband noise at 50 kHz offset and beyond and some rather bad discrete spurious outputs are poor by comparison and I am not particularly happy running it into a Legal Limit amplifier if there are stations in close proximity (20km). I realise that the KX3 is really designed as a QRP HF rig where such transmit noise and spurious outputs would be buried in the RF pollution on HF, but on VHF that isn't the case and greater care has to be taken. So, armed with recently published figures comparing various transceivers I am looking at alternatives, the K3S is the best of the bunch, then the K3. I am excluding the top of the range Flex, as I prefer a real radio with knobs on. See RadCom Magazine March 2016 p22-27 High Performance VHF/UHF contest stations by Alwyn Seeds G8DOH. Of course finding a used K3 with the right options that I need (and they quickly add up) may be a problem. Prices in the UK from the dealer are ? for $, so buying direct from Elecraft in the USA is a still a better deal even with today's high shipping costs and 20% VAT. At one time it was cheaper to take a transatlantic trip and bring a K3 back and still save money. Slightly below the K3 but better than the KX3 in transmit purity at 50 kHz offset is the TS-590SG and it has an easy hardware mod for general coverage transmit coverage, so that is another option. However I do like Elecraft so provided it can do what I need that is what I would prefer. I was surprised to find how out of calibration my transmit carrier null and opposite transmit sideband suppression was on my KX3 when I put it on an analyser. I was able to improve it by a great many dBs on all bands. I wonder as it was "built" by the UK dealer and I believe they align them. 73 from David GM4JJJ > On 22 Feb 2016, at 22:36, Don Wilhelm wrote: > > David, > > I don't know if the K3 transverter IF output is limited to the ham bands or not.

If you order the kit version, it should not be subject to customs fees, but VAT will still have to be paid. I believe there are benefits to ordering from Waters & Stanton, or from QRP Project in Germany. Extended warranty is one, and more local warranty service without the expense of shipping back to Watsonville, CA. I am lead to believe (but do not quote me), that W&S as well as QRP Project service only what they sell. There is an Elecraft Service Center in Italy that I believe services the full line.

I'll be getting one as soon as my tool budget allows. So many things require skills. But to get the skills, you have to do it! I'm sure putting in the effort will pay off. Also, I encourage the kids to build kits and such, so I'm not too worried about the dangers of tools like soldering irons or the hot-air stuff -- I've let them try the oxy-acetylene torch with supervision. I'm more cautious around tools that are unforgiving and will remove limbs. Who here hasn't burned themselves with a hot soldering iron? The kids are old enough to experience the price of carelessness... - Brendon On Sun, Feb 21, 2016 at 11:44 PM, Fred Townsend wrote: > Brendon there is no doubt a rework station will make things easier.

The blank display would be associated with the Front Panel board and the surrounding components (refer to the schematic to identify those components) and reflow those first. Ask him to reflow the soldering with an iron temperature of 750 degF or a bit more. Add a bit of additional solder (actually the additional flux is what is required). Observe the solder as the connection is heated, it must flow out onto the component lead and the solder pad fully before removing heat. There should be a small visible fillet of solder around the component lead. A solder "ball" can mask a bad connection, and if there is a ring around the component lead, that is also a problem. As one builder stated - the solder connection should look like a mountain, but not a volcano - I forget the source of that original comment, but it is a good description of a good/bad solder connection. Note also that the front panel switch leads do not project very far on the solder side, and it is possible to have soldering over the solder pad that does actually contact the switch lead. Re-flow the soldering with a tip width that allows the switch lead to be heated. Na alternative is to solder the switch leads from the component side of the board. Be careful not to let the soldering iron to contact and melt the switch body if you take that alternative. If he is using lead-free solder, bump the soldering temperature up to 800 degF. Note that lead free solder does not flow well. The use of lead-bearing solders is my recommendation (although Elecraft cannot officially acknowledge that fact due to RoHS compliance restrictions). The RoHS restrictions do not apply to ham built kits, but do apply to factory built assemblies. Since the K1, K2, KX1 and XV series transverters are kit built, the use of lead-free solder is not required. Since a K1 is not likely to be destined to the landfill, using leaded solder is not an impact to the environment - consumer "throw-away" devices are the major contributor to landfill lead, and properly should be RoHS compiant IMHO. If the soldering turns out not to be the problem, I would suggest that the next step is to refer to the DC Voltage chart in the last few pages of the manual. 73, Don W3FPR On 2/22/2016 5:34 PM, George Davis wrote: > A fellow club member is building K1 and has reached the Rx alignment stage.

Message-ID: <201602230223.u1N2NdME013301@mail41c28.carrierzone.com> David, I don't have an answer for your question though well aware that bandpass filter affect on use of K3 IF for transverters. For Rx, if you have the KBPF3 installed, it will extend beyond 14.350 but unknown if that is true for Tx. I use 28-32 MHz as IF for my VHF/UHF transverters up thru 1296. Many are probably unaware that the K3 will receive up to 32-MHz in transverter mode. However RF output drops off severely above 30-MHz. My 50w transverter output at 146.52 (IF=30.52) is 6w due to low drive from the K3. At 146.000 output is 15w. At 145.800 35w. And 144.000-145.500 50w. Use of my KX3-2M is for the full 144-148 MHz band, making it way more usable as a multi-mode 2m radio. But my use of the K3+ 2m DEMI transverter is primarily for the bottom end 144-144.200. I have 2m FM radios for the rest of the band (and the KX3-2M, of course). 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From W2NED at frontiernet.net Mon Feb 22 22:32:43 2016 From: W2NED at frontiernet.net (Ned Asam) Date: Mon, 22 Feb 2016 22:32:43 -0500 Subject: [Elecraft] [KX1] For sale on ebay Message-ID: <56CBD2DB.7010504@frontiernet.net> FYI: I just listed a KX1 for sale on ebay.

My query was a bit brief as I was not certain if I was still a registered user of the Reflector. A bit more information. Dave, the builder, and I were doing the Rx alignment, we had the intermittent fault which Dave had had before and he had associated it with the front panel and display board. Dave took off the front panel and the fault disappeared. We then carried out the alignment which went according to plan. Dave then refitted the front panel, the last part of which, fitting the two control knobs, brought back the problem. He is now going to follow the advice received and reflow soldered joints. George.

Yes I would not have the brass neck to expect the UK dealer to help if I had a problem after bypassing them on the purchase. It is unlikely I will buy anything other than a kit from the USA. So no customs duty, though sometimes the customs get that wrong and you need to appeal. There was a letter about that in Radcom this very month. Either that or a I get a used unit from someone in the UK. That is my preferred option and I have had one lead so far from a fairly local ham. I found some interesting info on the K3 transmit phase noise on various bands today. 14 MHz looks like one of the best bands to use as the IF provided I can transmit up to about 14.4 MHz. http://www.ok2kkw.com/next/staronove_vyzvy.htm and http://www.ok2kkw.com/xyz/om3w/transvertor_om3w_en.htm 73 David Anderson GM4JJJ > On 23 Feb 2016, at 00:16, Don Wilhelm wrote: > > David, > > Ordering direct from Elecraft, my understanding it that if you order the K3S-F you will endure both customs fees and VAT.

Assuming you're not using cross-mode, then you can just change the rate for A, and the rate for B will be the same. Normal tuning rate is 10 Hz per step. Tapping RATE switches to 1-Hz tuning. Holding KHZ switches to coarse tuning. All will apply to both VFOs. To change the coarse tuning rate for a give mode, use MENU:VFO CRS. To change the total steps per VFO knob rotation, use MENU:VFO CTS (128 or 256 counts per turn). 73, Wayne N6KR On Feb 23, 2016, at 9:15 AM, "Tim Cook" wrote: > Is there any way to change the tuning rate for VFO B?

Faced with exactly that issue, I chose Davis RF BuryFlex as the best compromise between shielding effectiveness and flexibility. I use only Amphenol 83-1SP connectors that I carefully solder myself. And I use only Amphenol adapters where required (elbows, barrels, Tees). When a male N-connector is required, I use the excellent Andros connectors. 73, Jim K9YC From gm4jjj at yahoo.co.uk Tue Feb 23 13:26:16 2016 From: gm4jjj at yahoo.co.uk (David Anderson) Date: Tue, 23 Feb 2016 18:26:16 +0000 Subject: [Elecraft] PX3 noise generated on KX3-2M In-Reply-To: References: Message-ID: <8510CA90-8DEE-47DF-9DE8-B480DF3CE491@yahoo.co.uk> This is something I had too using an external transverter for 144 MHz with my KX3 Chad. I wrote about my experience and how better grounding of the DC socket of the PX3 to the chassis reduced the radiated noise. Here are the details again: Since I purchased my PX3 I have suffered from radiated noise at 144 MHz. It takes the form of various buzzy spurs evenly spaced across the band and quite easily seen on another SDR. Even with just a power connector and no other leads connected I got this QRM. I was told this was normal and had to be expected with the switched mode regulators inside the PX3. Putting my hand near the screen of the PX3 made the noise stronger and louder, but sometimes putting pressure sideways on the DC power plug would almost eliminate it, unfortunately as soon as I released the pressure it came back again. I almost considered hiring someone to hold the plug for me while I operated the rig ;-) Getting totally fed up with this annoying noise, especially as one of the spurs was on 144.300 the SSB calling channel, I decided today to see if I could improve the situation, and I have. I had already checked that the DC Jack was grounded properly to the side panel. However what I hadn't appreciated is that the common of the PCB is connected to a switch in the Jack and is not directly connected to the chassis of the Jack. What was happening was the barrel of the plug was connecting to the pole of this switch and the PCB common, but only loosely to the chassis of the Jack. Movement of the plug sideways with enough pressure did connect the plug better to chassis and resulted in the noise going away. I opened up the back of the PX3 and connected the chassis part of the Jack to the PCB common side of the jack's switch by soldering a small piece of copper EMI tape across the gap. This ensures that the PCB common is stoutly connected directly to chassis at the DC Jack. This has had the desired effect, no more intermittent increases in spurs heard in the receiver as the leads are touched or moved, and no forest of spurs visible on the SDR when I turn on the PX3. I can now listen to relaxing white noise on 144.300 now without having to put the notch filter on to remove the heterodyne ;-) The usual caveats apply, don't do this modification unless you need to, and only then if you know what you are doing, take anti static precautions, and accept that it may or will invalidate any warranty you may have with Elecraft. 73 from David GM4JJJ 73 from David GM4JJJ > On 23 Feb 2016, at 18:06, Chad Wasinger wrote: > > Hi Group, > I wanted to post this question as it relates to noise generated by the PX3 that interferes on the KX3's 2 meter module.

David, Thanks for posting this. I've been bugging Wayne about these issues for more than ten years, and he still hasn't gotten the message. This is a great example of ignoring what EMC guru Henry Ott calls "the hidden schematic lurking behind the ground symbol," and which is a primary cause of EMC failures (RFI, hum, buzz). In the pro audio world, we call it "the Pin One Problem," whereby cable shields fail to contact the shielding enclosure at the point of entry, but instead go to the circuit board, finally reaching the chassis via a path established by the whim of the PC board layout artist. One VERY important correction to your post. This connection is NOT a "ground" or "earth," it is a BOND between the cable shield and the shielding enclosure. Or in the case of the power connector, between DC- and the shielding enclosure. The significance of this is that without that bond, RF can be coupled to that cable and radiated by simple antenna action. In addition, RF can be coupled from one cable shield to another, and from there to an input circuit. A connection to actual EARTH is NOT part of a solution to these problems, proper bonding IS critical to the solution. Neil Muncy, ex-W3WJE (SK) put this quite poetically in the tutorial workshops he did for audio professionals. Neil said, "Buy a six pack of your favorite beer, grab a chair and a set of good binoculars, and sit at the end of the runway of O'Hare (substitute your local airport) and CALL ME COLLECT when you see an aircraft take off trailing a ground wire." 73, Jim K9YC From jim at audiosystemsgroup.com Tue Feb 23 14:42:28 2016 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 23 Feb 2016 11:42:28 -0800 Subject: [Elecraft] Best Coax for Jumpers and Interconnections for SO2R operation with K3 & KX3 In-Reply-To: <922600342fc9e7ff93d57a109563679a.squirrel@www11.qth.com> References: <922600342fc9e7ff93d57a109563679a.squirrel@www11.qth.com> Message-ID: <56CCB624.60006@audiosystemsgroup.com> On Tue,2/23/2016 10:35 AM, john at kk9a.com wrote: > I have not seen any issues with Belden 9258 RG8X and Amphenol (solder) > connectors.

Tests have been done at 2 locations; my own home station and here at another property ( work in progress as we politely say..) about 125km south of Auckland. The same second harmonic garbage is heard at both places. Over the last day I have completely swapped out all the 80m and 40m antenna and feeder components here in the provinces. No change. What I now strongly suspect is the only common point at both locales; both properties have burglar alarms installed. Both are almost identical well known European name brand units. There is no detectable RF radiation from the processors or wiring. The clincher now that I think about the last time we ran 2 stations here without any drama was before the alarm was commissioned here. I have dropped the supply and backup DC to the alarm here without any change, Likely 3.5 meg RF is simply hammering the PIR's, cable runs are in the roof cavity. Can't %100 prove this without fairly major re-wiring, will leave it as is for the meantime, thanks again guys cheers from ZL Paul zl1ajy -- View this message in context: http://elecraft.365791.n2.nabble.com/Slighty-off-topic-80-meter-second-harmnic-how-to-stop-tp7614506p7614534.html Sent from the Elecraft mailing list archive at Nabble.com.

Do you mean "resellers," who take a percentage of our money for the wonderful "service" they provide? Like Elecraft, Davis RF has a website and you can order from them direct. This means no markup from a reseller, so we get the best bang for our buck. I've bought from Davis twice, and been quite pleased with their price, quality, and service. In addition to BuryFlex, I bought a spool of their RG11, which measures just like the much more expensive Belden 8213 RG11. The difference is advertising and markup by the dealers who sell Belden. My neighbor, W6GJB, has also bought from them, and has been quite pleased. Like any other good cable vendor, price will go down with quantity. I've bought 500 ft and 1,000 ft spools, but they will happily sell you much shorter lengths. 73, Jim K9YC On Tue,2/23/2016 1:41 PM, Robert Nobis wrote: > Thank you.

I had a bad problem with mine, cured by a 5th order 200 kHz lowpass filter where simple ferrites and caps did not work. The alarm system has low frequency digital data. I built it with some caps and a few turns on mix 31 cores I had. Since it is not a 50 ohm system, the filter is not exactly as designed, but it worked well enough to completely eliminate the problem. I put it at the alarm controller that was getting affected. 73, Mark W7MLG On Feb 23, 2016 2:04 PM, "paulb" wrote: > > Hello again folks > > Thanks to all for the suggestions and hints to what this problem could be. > > Tests have been done at 2 locations; my own home station and here at > another > property ( work in progress as we > politely say..) about 125km south of Auckland. > > The same second harmonic garbage is heard at both places.

Here are answers to many of those questions: 1. The meter I'm using in the test is a known-good MFJ-815B HF power/SWR meter. 2. I'm using a known-good 300W dummy load for my "antenna", so any reflected power is minimal, as is SWR. 3. I do have the internal ATU installed, but it is in BYPASS, as I have a resonant antenna on 20m-10m and use the KAT500 for 40m/80m, or when I run power. 4. Test results at lower power levels: 10m 10w out - 10w on meter; 25w out - 19-20w on meter; 50w out - ~30w on meter 12m 10w out - 10w on meter; 25w out - 20w on meter; 50w out - 30w on meter 15m 10w out - 10w on meter; 25w out - 20w on meter; 50w out - 35w on meter 17m 10w out - 10w on meter; 25w out - 20w on meter; 50w out - 35w on meter 20m 10w out - 10w on meter; 25w out - 20w on meter; 50w out - 40w on meter 40m 10w out - 10w on meter; 25w out - 20w on meter; 50w out - 40w on meter 80m 10w out - 10w on meter; 25w out - 20w on meter; 50w out - 40w on meter I also ran the TX Gain Calibration from the K3 utility one more time, with a different cable. Here are the results of that calibration (note - I didn't run the milliwatt calibration because I don't use a transverter with the IF Out. It just goes to my P3): K3 Tx Gain Calibration data written on 2016-02-23 at 22:18:30 K3 Serial Number 00281 K3 MCU revision 05.38. RS-232 speed 38400 bit/s.

It seems as if I am losing about 20% of my output power for any setting above 10w, except on 10m, where at 100w I seem to be losing about 50w. It also seems as if maybe there is an issue with the internal 100w PA, based strictly on my observations and a wild guess. If there are any other suggestions/recommendations, I'm all ears. If not, the next step is an email to the good folks in Aptos.

There were alarm wires running through the attic, and when I first tried it I actually vaporized a terminating resistor at one of the windows. Those wires were quite long and possibly resonant lengths. I solved the problem by installing no. 31 ferrite toroids on the alarm wires and also the power supply wires at the alarm control box. I wrapped as many turns of wire as I could on them. That might fix your issue.

I'm curious, however, why removing the 100W PA and running calibration tests at 10W would matter, if I'm already seeing expected results at the 10W power level. That is, I set the output power on my K3 to 10W, and transmit using a full duty cycle mode. On the external power meter, I see 10W, on all bands. This would seem to me to indicate that there isn't an issue with the low power amplifier.

Set the K3 to 5.5 watts and check power output on each band. Then set the K3 to 10 watts and check power output on each band. Then repeat the process at 55 and 100 watts. That should tell you if the LPA or KPA is compressing and will allow Elecraft Support (when you e-mail or call them) to focus on the source of your problem. If you have 5.5 and 10 watts (or close) at the low power test the LPA is OK and the KPA is going into compression for some reason (check power supply and the +13V pins on the headers). If you do not have 5.5/10W on the LPA test, your LPA is going into compression and it may need to be swapped or connections checked. 73, ...

With the 100w amp in place and the jumpers configured the data is speculative as to which circuits are in operation. The key to troubleshooting is to isolate. Don't assume data. Measure. You stated that your wattmeter is "known good", how/how recently did you get the calibration checked? Verify switch settings for the ranges? I usually trip on the simple things that, if known, would make me appear simple minded...but we won't discuss my past lumberings... :) Since the PA is trivial to remove is there any good reason to not do so? Logical assumptions based on the data so far: 1. The 100w amp is working by netting greater than 10w 2. We don't know the status of the 10w amp but since it drives the 100w amp we're getting something out of it. 3. We don't know how much power the 10w amp is outputting at full drive. 4. The rig was most likely OP assembled or an add on installed --- you may clarify the case here. 5. Wiring is suspect - Personally I had challenges here when installing the ATU and some other things.

It is not necessary to remove the 100W amp. Simply dial the power back below 12W and it will be bypassed. Thus my procedure to check power at 5.5/10 and 55/100 W ... using 5.5 and 55 avoids triggering the power calibration routines which occur at 5.0 and 50 W. Since the output is compressing at 60 to 80 Watts, the compression point will be readily visible with the 5.5/10 and 55/100 tests. 73, ...

I need to cover from 14.000 to about 14.400 MHz on transmit for the weak signal end of the band. I believe that the K3 can be enabled via software to transmit outside the limits of the ham bands. The question is do I require the general coverage bandpass filter option to allow transmission just for that extra 50 kHz above 14.350? I will be using the transverter output not the HF antenna for this.

I originally thought that it would be considerably less expensive, though risky if warranty repair was ever required, to directly import. I now realise that with the fall in Sterling against the Dollar, that there is very little in it as far as price goes, by the time shipping and VAT at 20% is added to the total. I am still trying to decide whether to go the whole hog and get a new K3S kit or hold out for a used K3 with the options I want. I could upgrade the K3 with new synth etc later, but in order to bring it up to the K3S spec would require about ?860, so the max I could pay for the K3/10 would be ?1190 and that would have to be a pretty new bare K3/10, I would think it is unlikely I would find one at that price. Looks like a new K3S is the most sensible option, but if a good K3 came up at a very good price I would still go for that. 73 from David GM4JJJ From ab7r at cablespeed.com Wed Feb 24 12:26:34 2016 From: ab7r at cablespeed.com (ab7r at cablespeed.com) Date: Wed, 24 Feb 2016 12:26:34 -0500 (EST) Subject: [Elecraft] panavise and hakko 963 In-Reply-To: <1161095086.52739043.1456330756725.JavaMail.zimbra@cablespeed.com> References: <1161095086.52739043.1456330756725.JavaMail.zimbra@cablespeed.com> Message-ID: <1382011241.52743756.1456334794208.JavaMail.zimbra@cablespeed.com> Typo....it is a Hakko 936....sorry. ----- Original Message ----- From: ab7r at cablespeed.com To: Elecraft Reflector Sent: Wed, 24 Feb 2016 11:19:16 -0500 (EST) Subject: [Elecraft] panavise and hakko 963 The Panavise is sold.....Hakko 963 still available.

The aluminum tape shield oxidizes in presence of moisture with resulting change in impedance and attenuation. I just replaced a 45-foot run of LMR-600 which hangs off my eme tower supported by a pilot cable. Because it is run vertically water entered the upper connector and pooled at the bottom connector such that when I pulled off the N connector water poured out in a stream for a couple minutes. I finally had to replace the run as SWR would rise every time temperature went above 32F. After removal I cut away sections of the bottom end of the cable to reveal that about 18-inches had badly corroded. New LMR-600 run has my 2m SWR lower (0.14) than it has been for about three years (so this condition had been increasing over time). I run LMR-400, LMR-400UF, LMR-240 and LMR600 outside (along with LDF7-50A and LDF5-50A Heliax). Heliax appears to totally isolate moisture to outside the copper shielding if connectors are well constructed and sealed. I use the LMR-240 for receive lines after my preamps to run down to ground level where I connect LMR-400 to continue to the "shack". LMR works just fine if you keep moisture from entering the coax. Only runs of RG-213 are to my 600m inverted-L, 80/40m inverted-V and to my tribander yagi. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From cautery at montac.com Wed Feb 24 13:26:10 2016 From: cautery at montac.com (Clay Autery) Date: Wed, 24 Feb 2016 12:26:10 -0600 Subject: [Elecraft] Best Coax for Jumpers and Interconnections for SO2R operation with K3 & KX3 In-Reply-To: <201602241739.u1OHdjS9006321@mail41c28.carrierzone.com> References: <201602241739.u1OHdjS9006321@mail41c28.carrierzone.com> Message-ID: <56CDF5C2.8020100@montac.com> For exterior use, I choose to use the LMR-xxx-DB series which is impregnated with a moisture reduction substance.... intended for direct burial, it adds an additional measure of protection. ______________________ Clay Autery, KG5LKV MONTAC Enterprises (318) 518-1389 On 2/24/2016 11:39 AM, Edward R Cole wrote: > Just a comment on Times Microwave LMR cables: > > In outdoor application its "VERY" important to seal connectors properly. > > The aluminum tape shield oxidizes in presence of moisture with > resulting change in impedance and attenuation.

(Spectra view or other SDR from the radio would also work.) I also used an audio frequency counter to monitor the stability of the cw note. I think it took two runs because by the second time, I was familiar with what the radio would do and was familiar with the functions. Anyway second time was the charm. ??

I think the relays are on the new Synt-boards? Everything works.

With the new synth boards and the updated software, you can do diversity without matched filters, but the K3 handles the synthesizers differently that it does with matched filters. If you do have some unmatched filters, the K3 will use both synthesizers (instead of slaving the sub off the main synth) - and that could be the reason for the relay clicks. 73, Don W3FPR On 2/24/2016 6:13 PM, Bill OMara via Elecraft wrote: > Thanks Arie...

The problem with fragmented disk volumes is that the parts of a file get scattered all of the disk. That means it takes multiple seeks to get an entire file. De-fragmenting organizes each file in neighboring blocks on the same cylinder, so the file can be accessed with the fewest number of seeks. SSDs don?t seek. Any block anywhere on the SSD can be read with no delay. The only effect of de-fragmenting an SSD would be to shorten its lifetime by doing unnecessary writes. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Feb 24, 2016, at 1:22 PM, Bill wrote: > > Identical SSDs.

Your RX EQ settings will have to be customized to your ears and the listening devices you typically use (headphones, speakers, etc.). I just leave mine set flat for both SSB and CW. Make it sound 'natural' to your ears. For the SSB Lo and Hi cut points, I generally start out with 200 to 300 Hz as the lo cut point, and 2800 to 3000 for the high cut point. If I find interference on the high frequency side, it is an easy matter to reduce the hi cut, and you will be surprised how much it can be cut while still maintaining intelligibility. Interference on the low frequency side is more difficult to combat since you will lose significant intelligibility if you increase the low cut significantly. With the NR settings, you will have to experiment. It will depend on the type of noise you are trying to deal with. 73, Don W3FPR On 2/24/2016 6:29 PM, Doug Renwick wrote: > Have a new K3S and need to find the best settings. > What are people using for their SSB and CW RX EQ 8 band settings. > Same for the SSB Lo and Hi cut points. > What seems to be the best NR settings. > From vk1zzgary at gmail.com Wed Feb 24 19:13:13 2016 From: vk1zzgary at gmail.com (Gary) Date: Thu, 25 Feb 2016 10:13:13 +1000 Subject: [Elecraft] K3 RX EQ Settings In-Reply-To: <56CE4191.2060601@embarqmail.com> References: <120CB62A60D145F1B90187039C54E36E@DOUG8PC> <56CE4191.2060601@embarqmail.com> Message-ID: <56ce4736.da10620a.ccd30.1df8@mx.google.com> This is me, not for all folks ok? 1.8 filter installed, Hi Cut set to 1.7 - 1.8, Lo Cut set to .10.

Best you look in Task Manager (with show process from all users selected) to see what the differences are between the two instances of the OS. Do that BEFORE starting HRD, and after. Assuming you are the same class of user on both systems, and both HRD's have EXACTLY the same configuration. ~~~ On 25/02/16 00:13, elecraft-request at mailman.qth.net wrote: Date: Wed, 24 Feb 2016 15:49:37 -0500 From: Bill To:elecraft at mailman.qth.net Subject: [Elecraft] HRD question Message-ID:<56CE1761.6030104 at nycap.rr.com> Content-Type: text/plain; charset=utf-8; format=flowed Has any one experienced a distinct slowdown of HRD initiating on Win 10? I just put a Win 10 drive on my computer from about six weeks ago and it initiates in about six seconds. On the current Win 10 drive, it takes about 25 seconds. The only difference between the drives is that the slower drive is current with updates. This makes me think there is something wrong with an update. Anyone else experiencing this?

What are good reliable places to sell my radios? (FT-950 and FT-857D). I've successfully used eham classified for many years. As with any public site like this there are scams. Read the advice on the site and use common sense. I specify in my ads that I will sell only to a US licensed ham for shipment to his FCC address. That makes it awfully hard for scammers, and I don't have to deal with shipping out of the country to an address I can't document. 73, Jim K9YC From w2blc at nycap.rr.com Thu Feb 25 13:53:06 2016 From: w2blc at nycap.rr.com (Bill) Date: Thu, 25 Feb 2016 13:53:06 -0500 Subject: [Elecraft] HRD question In-Reply-To: <56CF0186.6010806@googlemail.com> References: <56CF0186.6010806@googlemail.com> Message-ID: <56CF4D92.6030005@nycap.rr.com> A full reinstall of Win 10 was made and the problem went away.

From pauls at elecraft.com Thu Feb 25 17:42:34 2016 From: pauls at elecraft.com (Paul Saffren N6HZ) Date: Thu, 25 Feb 2016 15:42:34 -0700 (MST) Subject: [Elecraft] P3 v1.57 / SVGA v1.31 BETA firmware available Message-ID: <1456440154088-7614603.post@n2.nabble.com> BETA firmware packages for the P3 & SVGA are now available for download from the Elecraft website. These BETA versions contain new features as well as several bug fixes. With these versions we introduce the ability to embed P3 commands within SVGA keyboard macros. Also new is the ability to map the first 8 keyboard macros to any of the 8 FN keys located on the front panel of the P3. Refer to the release notes below for more information Please direct all issues/questions/etc to: alan at you know where dot com pauls at you know where dot com 73, Paul n6hz To load beta firmware on to your P3/SVGA: 1) Create a temporary folder. 2) Download the beta firmware from: ftp://ftp.elecraft.com/P3/firmware/beta/P3_0157_SVGA_0131_BETA.zip 3) Extract the contents of the zip file into the temporary folder. 4) With your P3 connected via serial cable, start P3 Utility and select the Firmware Tab 5) Click on Browse and select the temporary folder that holds the extracted files. 6) Click on "Send all new firmware to P3" Release notes: MCU 01.57 / 2-2-2016 Version 01.57 requires SVGA firmware 01.31 to support all SVGA features. * P3 commands in keyboard macros: Added support to allow P3 commands to be embedded in SVGA keyboard macros. When entering a keyboard macro using a USB keyboard attached to the P3/SVGA, P3 commands can now be intermixed with K3 commands by preceding the command with the ?#? character. Example: set up a macro to set the K3 to PSK31, frequency 14.070, P3 span of 100 kHz, fixed tune enabled: FA00014070000;MD6;DT3;#SPN001000;#FXT1; * SVGA keyboard macros as function keys: The first 8 SVGA keyboard macros can now be executed from the 8 front panel function keys. First, using a keyboard, program the macro and make sure to save it into one of the first 8 locations (mem 1 ? 8). Then on the P3, press the MENU button and using the encoder, select the SVGA menu and press the encoder to enter. Then using the encoder, choose ?Macro 1? through ?Macro 8?, then press the function key (short tap or long hold) to map the macro to the function key. * Enable/disable TX sensing at the TxMon coupler: Added TxSensEn to TxMon sub-menu. This allows enabling/disabling of transmit sensing at the coupler. For K3 and K3S users, TxSensEn can be set to ?disabled?, which will use the serial connection from the K3 to determine the TX state. Setting TxSensEn to ?enabled? will use forward power sensed at the TxMon coupler to determine TX state (useful for non-Elecraft radios). * K3S attenuator support: The P3 now properly scales the display when the four-step attenuator in the K3S is enabled. * SWR meter blanked: Both the analog and digital SWR displays are now blanked whenever the transmit power is too low to give a valid reading. * Serial #DSM command: The Display Mode (#DSM) command now controls the Transmit Monitor's power/SWR meter display as well as enabling and disabling the waterfall window. #DSM0 = Spectrum display only, #DSM1 = Spectrum + waterfall, #DSM2 = Spectrum + meters, #DSM3 = Spectrum + waterfall + meters. * New #FON command: The display font can now be selected via a serial command. #FON0 = 5 x 7 pixels, #FON1 = 7 x 11 pixels, #FON2 = 9 x 14 pixels. * New #XCV command: The transceiver type can now be selected via a serial command. #XCV00 = "K3", #XCV01 = User-defined, #XCV03 = 455 kHz IF, etc. The command uses the same number order as in the "Xcvr Sel" menu item. * Transceiver definition bug fix - Exiting: When exiting the "Xcvr Def" menu page, if the user-defined transceiver is already selected, it will reflect the new values inmmediately, rather than having to re-select it. * Transceiver definition bug fix - IF Invert: The USER transceiver that is defined in the "Xcvr Def" menu item may now specify "Not inverted" IF tuning even if the "K3" control language is selected. * SVGA resolution / main waterfall bug fix: The main waterfall height had been switching to the default value after changing SVGA resolution. * VFO B cursor = VFO DATA A bug: The VFO B cursor had been matching the VFO A cursor in DATA A mode, even when VFO B was in a different mode. P3SVGA 01.31 / 2-3-2016 * SVGA Keyboard Added support to allow P3 commands to be embedded in SVGA keyboard macros. Added support so P3 can execute keyboard macros from front panel function keys. Keyboard / USB thumbdrive can be used when not in data display mode. Cleaned up the text message sending, and use of the IM character ?|? for better handling of short text messages. -end -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-v1-57-SVGA-v1-31-BETA-firmware-available-tp7614603.html Sent from the Elecraft mailing list archive at Nabble.com.

The important note # 5 I overlooked during manual scanning.. a bit obscure I personally would probably promote that to a section in the manual called dual sensor operation. JM2C When you are using 1 meter with 2 antennas and have installed both sensors, hold down the sensor button and that puts the sensors into a polling mode. It is reflected by a rapid flickering of both sensor lights. Then the software and meter will reflect the RF to the sensor currently being transmitted. The flickering lights are a bit.. err. much.. but it all works FB. Just down drive RF through both sensors at the same time or it will confuse the electronics and not display useful info.

This is not possible with the W2 and you would need 2 wattmeters. But it works for 2 antenna SO2R. Perhaps with a W3? ;-) ;-) ~C./WM -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Chris Tate - N6WM Sent: Thursday, February 25, 2016 4:21 PM To: Dave G3WGN M6O ; elecraft at mailman.qth.net Subject: Re: [Elecraft] and now something completely different.. the w2 Hi Dave hope all is well, haven't seen you for quite a while now.

The important note # 5 I overlooked during manual scanning.. a bit obscure I personally would probably promote that to a section in the manual called dual sensor operation. JM2C When you are using 1 meter with 2 antennas and have installed both sensors, hold down the sensor button and that puts the sensors into a polling mode. It is reflected by a rapid flickering of both sensor lights. Then the software and meter will reflect the RF to the sensor currently being transmitted. The flickering lights are a bit.. err. much.. but it all works FB. Just down drive RF through both sensors at the same time or it will confuse the electronics and not display useful info. I Again thanks to the W6FVI and W6FB for your help and G3WGN/M6O for your calls and pointing to us 6 landers!

The accessories that I have match well with the "Buddipole deluxe" version that the manufacturer now sells. Included are a tripod and mast, buddipole matching carry bag, clamp for vertical configuration (with counterpoise), 25-foot coax feeder with choke and rotating arm kit. Everything is in good working order. One of the telescopic whips has a very minor bend in it that has not affected performance. I am looking to sell for $295, plus shipping. (Or local pickup in the Dallas, TX area.) This includes the Buddipole, tripod, mast, feed line, vertical configuration adapter with counterpoise and carrying case. Paypal is preferred. If you are interested please feel free to email me at n1ko at arrl.net, or reply here. I would be happy to send you pictures of all the items .

The important note # 5 I overlooked during manual scanning.. a bit obscure I personally would probably promote that to a section in the manual called dual sensor operation. JM2C When you are using 1 meter with 2 antennas and have installed both sensors, hold down the sensor button and that puts the sensors into a polling mode. It is reflected by a rapid flickering of both sensor lights. Then the software and meter will reflect the RF to the sensor currently being transmitted. The flickering lights are a bit.. err. much.. but it all works FB. Just down drive RF through both sensors at the same time or it will confuse the electronics and not display useful info.

That is the first thing I was attempting to do after updating to P3 v1.57 -- Although have yet to get it to work completely. It appears that some of the individual commands in the sequence are not being executed due to the speed at which they are executed from the macro. The P3 is single threaded so inputted commands could be missed while it is handling other things. Using Tim's (A45WG) idea for a CW pileup macro, I recently extended it for an SSB view in a python script run from a serial port connected host. The meat of that script boils down to this macro form: #FXT0;#FXA0;#SPN000300;UP7;UP7;#FXT1;#FXA1;DN7;DN7; There may be other ways to accomplish this feature however. When this string is assigned to a P3 macro position and executed, only a few of the pieces get executed properly. I have been advised that inserting other commands that do "inquiries" may be useful to add pacing to the sequence. These queries are commands that ASK for a result, like FA to get current frequency from the K3. The response is discarded of course, but the delay might be useful in wasting time while the P3 is "busy." I'm still tinkering with getting this concept to work. Feel free to help me tinker with it. I have however, gotten it to work perfectly using a Genovation keypad. I have split the above string into seven distinct macros in the P3, then I trigger each one in sequence from a single key on the Genovation keypad. The software for the Genovation keypad allows you to put in a selectable delay between "keystrokes" so I have got it working well with 100ms of delay after each # command. The K3 UP and DN commands seem to operate well without any pacing between/or after them. I only tried this a few times, first starting with about 30 ms of delay, and that wasn't enough. It started to work at 100ms. Your mileage may vary.

I believe it is more or less general coverage transmit out of band, and if you are a good bit out of band the KBPF3 will be required as well. The only fly in the ointment is that 27 MHz is never properly unlocked in case CB guys try to use the rig, and the power amplifier isn't enabled for 27 MHz (don't know the exact frequency limits). However this probably means that the transverter ports would still work at those frequencies. Best to drop a line to Elecraft Support or phone and ask the question. Hope it goes well. 73 from David GM4JJJ > On 26 Feb 2016, at 02:45, Bert Rollen wrote: > > Rats.

If you are doing high volume, that makes sense. http://pages.ebay.com/sellerinformation/stores/Subscriptions.html For the regular user, having a store doesn't make sense. Fees for regular folks are 10% on the final value of the auction price (more if you have a reserve price or other options). Plus, PayPal takes ~3% off the transaction off the top. Then, eBay takes 10% of the amount of shipping you charge, too (!). http://pages.ebay.com/help/sell/fees.html If a regular seller (not someone with a Store) can get away with not using PayPal, I'd love to know how.

In-Reply-To: References: Message-ID: For eBay, I do have a few recommendations (having just sold a couple of laptops). When you're creating the auction, there's an option to use the advanced listing tool - do that. You can require that people pay immediately when they use the Buy It Now option. This helps avoid a lot of scams where people try to "wire funds in a few days" outside of eBay. You can also list at a fixed price and avoid the auction altogether. eBay does a really good job of telling you the range of prices you can expect to sell something for and even suggests a price that's likely to get it sold in a short time frame.

Long story on how I arrived at this question in terms of troubleshooting something I've noticed in my K3 and K3S, but I'm just curious if there's supposed to be a noticeable difference? My assumption is the 8 poles are going to have a little more attenuation than the 5's, perhaps by as much as 3 db or more. Is that the case that ya'll have noted? I've looked through the list archives and haven't found a prior discussion of this, so just wondering.

The problem is likely that the K3 commands take a little longer to execute and there is no waiting in the P3 for the K3 to change frequency. In other words, the P3 executes the serial commands in sequence. It gets to a K3 command (DN7, UP7 etc) and simply sends that over to the K3. It then continues to execute the commands in the macro. Using the P3 and/or K3 utility delivers the same results as would any program (Python, etc) that does not query the K3 for a reply. While adding a delay after the K3 commands may help, there is probably a better way to do this. Let me think about it for a while.

Yes, but the difference doesn't matter -- it's in the IF, not the front end. Further, there is an menu adjustment for each filter to equalize the IF gain when switching between filters. The advantage of 8-pole filters is smoother response in the passband of wider filters, and steeper skirts. In general, roofing filters are only needed for high QRM conditions like contesting. Their function is to protect the DSP from overload by strong signals outside the desired passband. When the DSP IF is set to a bandwidth close to that of the roofing filter, the two filters cascade to provide even steeper skirts. Again, needed only under contest conditions. It's amazing the things one can learn by reading the manual. :) 73, Jim K9YC From lstavenhagen at hotmail.com Fri Feb 26 12:22:37 2016 From: lstavenhagen at hotmail.com (lstavenhagen) Date: Fri, 26 Feb 2016 10:22:37 -0700 (MST) Subject: [Elecraft] K3 5 pole vs 8 pole filters - attenuation in the passband In-Reply-To: <56D08637.5020402@audiosystemsgroup.com> References: <1456505456690-7614635.post@n2.nabble.com> <56D08637.5020402@audiosystemsgroup.com> Message-ID: <1456507357324-7614639.post@n2.nabble.com> Well, yes, to spill the beans on this: it was when I was reviewing the filter gains on my K3 the other day that this came up. I built my K3 with the stock 2.7khz 5 pole filter in FL1 and an 8 pole 400hz in FL2 - however, to even out FL1 and FL2 requires the gain to be nearly maxed out for FL2 (8 db gain, IIRC). My K3S, however, has 8 pole 2.8khz and 400hz in goth FL1 and 2, respectively. But they're almost dead even in terms of attenuation with FL2 set at only 2 db gain. So that led me to wonder if the 5 pole in my K3 had less attenuation in general, accounting for the difference. Just a curiosity for me. 73, LS W5QD -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-5-pole-vs-8-pole-filters-attenuation-in-the-passband-tp7614635p7614639.html Sent from the Elecraft mailing list archive at Nabble.com.

Or check if you know your buyer/seller and have trust (or endure 10-20 day wait for checks to clear). I buy/sell for personal use and also run a "small" ham business. I have been building DEMI transverter kits and recently began building a 80w 2m linear amp. I was just notified that DEMI has sold off the VHF/UHF transverter part of their business so I am "out of business" building their kits.

At least for domestic payments, checks are normally truncated at the bank of 1st deposit (paper checks generally no longer get moved around like the ?good old days") and the exchange of funds is handled through ACH/ETF. A check should actually clear in 2-3 days at most. I've frequently taken a personal check payment if I know the buyer personally or by reputation, and I don?t recall having to wait any extraordinary time for a deposited check to show as ?cleared?. I?ve used the QTH list, reflector postings and eBay for buying and selling (mostly buying, to the chagrin of my bride). They all work fine. eBay takes too much, but then I?ve found you often get a higher selling price on eBay, too, because the market is just bigger. The thing that bothers me about eBay the most is that they actually consider ?shipping? to be part of the item's ?value? and take a cut of what is your COST to ship. It?s only a few $$ usually, but it just makes me grit my teeth in disgust. Hamfests are at the bottom of the list ? no matter how little you think you?re asking for something compared to perceived value, someone will stop by and tell you how (1) they won?t pay the eBay price, (2) they?d never pay that because they found one on a curb once or (3) they got theirs for $25 from a dying widow. I was once told that, because I wouldn?t come down another $5.00, it was MY fault that her grandson couldn?t have an ice cream on the way home. And from bitter experience I won?t ever buy anything at a hamfest from someone that I don?t know and who promises that if I ignore the rust (just needs some paint) ?it works perfectly? ;-) Grant NQ5T K3 #2091, KX3 #8342 From n1al at sonic.net Fri Feb 26 14:41:46 2016 From: n1al at sonic.net (Alan) Date: Fri, 26 Feb 2016 11:41:46 -0800 Subject: [Elecraft] P3 v1.57 / SVGA v1.31 BETA firmware available In-Reply-To: <1456506318750-7614637.post@n2.nabble.com> References: <1456440154088-7614603.post@n2.nabble.com> <56D05A1A.5050700@gmail.com> <1456497171.2828.5.camel@nk7z.net> <1456506318750-7614637.post@n2.nabble.com> Message-ID: <56D0AA7A.6020500@sonic.net> Yes, the issue is that after the P3 sends the UP7, DN7 command, etc. to the K3 it doesn't receive the new frequency back from the K3 right away. So when the #FXT1 command (go to fixed-tune mode) is executed it is based on the old K3 frequency, not the new one. Adding a delay in the Genovation keypad solves the problem because it gives the K3 time to update the P3 with the new frequency before executing the #FXT command. Paul and I have been talking about it and may have come up with a better way to do this. Stay tuned.

I will rephrase-- the P3 fails to control the K3 when using some macros in sequence, due to the P3 failing to implement flow control, and the P3 overrunning the K3. End result is the same however-- the P3/K3 cluster fails to execute some macro strings correctly. ?My problem is that I tend to be P3 centric as it is the device sending the macros, hence why I was calling the P3 as the issue. Today a solution was offered on the mail list, which allows the offsetting of the P3 screen, (for pileup use), if one is using the Genovation pad, or a Python Script. ?I will be implementing it later today via the Genovation, and testing via Python as well.? I spoke to Alan via email, and he was suggesting a fix, so something might be in the works already, you may want to check with him! ? I sure hope so! ?I don't really want to use up 5 or 6 macro positions in the P3 unless I have to...

A friend wants to buy my K3 and fit it with the most advantageous filters for his contesting methods. I remember when selecting filters back in 2009, the consensus was the 8 pole 250 Hz filter was more desirable than the 5 pole 200 Hz filter. Now its 7 years from back then, I don't know what is the current consensus. I bought the 8 pole 250 for the main & Sub Rx boards. Which filter between the 5 pole 200 & 8 pole 250 Hz filter is currently the most desirable for contesting conditions? Thanks & 73, Gary KA1J Hi all, Quick question - do the 8 pole roofing filters have more attenuation, as a general rule, in their passbands than the 5 pole? Long story on how I arrived at this question in terms of troubleshooting something I've noticed in my K3 and K3S, but I'm just curious if there's supposed to be a noticeable difference? My assumption is the 8 poles are going to have a little more attenuation than the 5's, perhaps by as much as 3 db or more. Is that the case that ya'll have noted? I've looked through the list archives and haven't found a prior discussion of this, so just wondering.

I am currently upgraded to ver. 9 because it had a KX3 interface. As I have been using it in the learning mode, I find that the error trapping is not good and the program constantly crashes when I try to do something the software does not expect. It is extremely frustrating to use. I would be interested in changing to another logging/tcvr interfacing software program. What has been your experience with these programs and what do you think are the best one's out there at this time. I want something that will look up callsigns as I enter the calls, and it would be nice to have forms that can be edited and the fields moved around.

Do you have a saved configuration file from sometime before this problem came up? If so, try an EEINIT (Reset to Factory Defaults) and then restore the configuration file. The Reset to Factory Defaults will wipe out the calibration and configuration data that is particular to your K3. That is why saving a configuration file is important. K3 Utility makes it easy to save and restore a configuration file. Reloading the firmware will not change the configuration settings. If you do not have a saved configuration file, you can still do the EEINIT, but you will have to do all the calibration procedures listed in the manual and activate whatever options you have installed in the menu. 73, Don W3FPR On 2/23/2016 4:31 PM, Jeff Schmidt wrote: > I can no longer select low cut/high cut (vs. shift/width) in LSB/USB. > A little homework reveals that this as a known side effect of changing > the passband shift from its default. > I'm sure I must have changed the PB CTRL to .01 at some point, but I > can't seem to change it back; a firmware reload didn't help.

It is not a "pin 1" problem. The metal shell of the chassis-mount power supply connector is mounted directly to the metal side panel of the PX3 and the paint is masked around the hole to make sure it makes a good connection.

The power jack has three pins, the connector shell (tied to the printed circuit board ground plane in the PX3), the center pin (connected to the +12V input) and a switch. The switch shorts to the connector shell when nothing is plugged in and opens when a power plug is inserted. But the thing is, the switch is not used and that pin is not connected to anything inside the PX3. (The only reason I used a jack with a switch was that it was the only suitable chassis-mount type I could find.) Besides, that pin is internally disconnected whenever the plug is inserted anyway. I just confirmed all that by double-checking the PCB artwork and by measuring an actual PX3 with an ohmmeter. If you'd like to check it yourself, the three connector contacts are arranged like this: The switch pin is the one on the side of the connector. The +12V pin is the one farthest from the panel. The shield/ground pin is the one that is almost hidden underneath the connector. > I opened up the back of > the PX3 and connected the chassis part of the Jack to the PCB common > side of the jack's switch by soldering a small piece of copper EMI > tape across the gap.

It sounds like you probably connected the switch contact to the connector shell, but I don't see how that could have affected anything since that contact is disconnected whenever a plug is inserted and it's a no-connect on the PC board. You might check to make sure the mounting nut on the power connector is good and tight and the connector body is making a solid contact to the inside of the side panel. I'm guessing that's the most likely cause of the noise radiation.

The switch doesn?t connect to anything, BUT the contact connection to the barrel of the plug makes much better contact to switch contact spring than the regular connection. > Movement of > > the plug sideways with enough pressure did connect the plug better to > > chassis and resulted in the noise going away. This is the problem, not the connection from the socket to the chassis which is perfectly fine. It is the relatively poor connection between the plug and socket. Exerting sideways pressure decrease the contact resistance from DC return to the chassis. Note nothing to do with the tightness of the nut on the socket, that wasn?t moving and was not slack. > > I'm trying to understand that.

(The only reason I used a jack with a switch was that it was the only suitable chassis-mount type I could find.) Besides, that pin is internally disconnected whenever the plug is inserted anyway. However using the unused switch contact switch is a much better connection from plug DC return and connecting that to the chassis reduced the intermittent poor contact bonding between the DC plug and the chassis. > > I just confirmed all that by double-checking the PCB artwork and by measuring an actual PX3 with an ohmmeter.

It sounds like you probably connected the switch contact to the connector shell, but I don't see how that could have affected anything since that contact is disconnected whenever a plug is inserted and it's a no-connect on the PC board. By connecting that very good connection between the switch contact and the barrel of the DC plug to the chassis of the PX3 with a very short wide piece of copper tape the resistance from barrel to chassis was consistently low and the radiated noise was eliminated. > > You might check to make sure the mounting nut on the power connector is good and tight and the connector body is making a solid contact to the inside of the side panel. I'm guessing that's the most likely cause of the noise radiation. No, that was not the case, it was the very first thing I checked. It is purely the contact resistance from plug outer to the socket not being good enough, and the solution was to reduce that by using the unused contact going to the switch and bonding that contact to the chassis as well. It completely eliminated the problem I had. 73 David GM4JJJ From rodenkirch_llc at msn.com Sat Feb 27 07:51:00 2016 From: rodenkirch_llc at msn.com (Jim Rodenkirch) Date: Sat, 27 Feb 2016 05:51:00 -0700 (MST) Subject: [Elecraft] Logging Programs In-Reply-To: <56d133f0.0c46620a.dc36b.620c@mx.google.com> References: <000001d170ed$b410e060$1c32a120$@comcast.net> <56d133f0.0c46620a.dc36b.620c@mx.google.com> Message-ID: <1456577460560-7614666.post@n2.nabble.com> I'm surprised no one has suggested N1MM....I believe it meets his requirements...or, did I miss something? 71.5 de Jim Rodenkirch K9JWV -- View this message in context: http://elecraft.365791.n2.nabble.com/Logging-Programs-tp7614653p7614666.html Sent from the Elecraft mailing list archive at Nabble.com.

I do find that a bandwidth less than 400 Hz is sometimes useful in heavy QRM, but I think the 400 Hz filter and DSP would be adequate.

A DSP filter of 250 Hz is a bit narrow, but with a 350 Hz DSP setting and the 250 Hz roofing filter, I still get good copy. That being said, most of the time I operate RTTY with a 500 Hz roofing filter and the DSP filter at 400-450 Hz; I only use the 350 Hz setting when there is a strong signal shoulder-to-shoulder with the one I am trying to copy. 73, Rich VE3KI WK6I wrote: > For RTTY the sweet spot is 400.

That's not enough to make a real difference *as a roofing filter* since the primary selectivity of the K3/K3S is in the DSP. 370 Hz is the minimum necessary bandwidth for a 170 Hz shift 45.45 baud FSK signal ... any tighter than that and the loss of sideband energy creates increased inter symbol interference (one bit gets "smeared" in to the next). The 400 Hz filter is really the one to have for RTTY - even if the DSP is tightened below that on occasion. It is a shame the Elecraft 200 Hz filters are no longer available - they were superior overall for very tight CW (tighter than the 250 Hz, 8 pole filters all the way to -40 or - 50 dB) and provided a real difference from the 400 Hz filters. If one really *must* have the 250/370 Hz filter, the next filter to have would be the Elecraft/Inrad 1000/1060 Hz, the custom UnPCBS 700/785 Hz filter, or perhaps the Inrad 500/550? Hz 8 pole filter (although the difference between the "250" and "500" is rather small but not as small as between the 250 and 400 nominal filters). Remember, the purpose of the first IF ("roofing") filter is to protect the If and Analog to Digital converter (ADC) from strong, adjacent signals, *not* to provide the final selectivity as in the case of a conventional superhetrodyne receiver. 73, ...

In the manual, it shows that for that group of capacitors, it could be a disc ceramic type OR a monolithic. Most likely it will be monolithic, either yellow or possibly blue. Not sure why the part you mention has 330 on one side and 470 on the other. One helpful reason to do an inventory at the start is to help work out through a process of deduction/elimination how to interpret the markings in cases where there is ambiguity. Maybe if you posted a closeup picture of both sides we would help identify the part. 73, Matt VK2RQ Sent from Outlook Mobile On Sat, Feb 27, 2016 at 9:04 AM -0800, "Rick A." wrote: Hi all, I am working on assembling my K2 and for component C73, 47uf, all I have in my kit is a yellow colored cap that has 470 on one side & 330 on the other side.

Have to remember that the 250 filter is the filter that INRAD designed for use in the FT1000MP series, as part of a cascaded PAIR of filters where the pair was a top shelf 250. The pair was the 8 MHz IF and 455 kHz IF filters in series. The "250" 8 pole and the DSP set at 250 work very well together, good enough for any of my needs. With the "250" defined as 350 in the K3, and the DSP at 350, you have very sharp skirts eminently useful for crowded contest work. 73, Guy K2AV On Sat, Feb 27, 2016 at 11:21 AM, Scott Ellington wrote: > I have both the 8 pole 400 Hz and 250 Hz filters.

I have not had to increase the price of my mini-module enclosure line in over three years. But with steady increases in my raw material costs and their associated shipping costs, I am forced to raise my prices 5 - 10% (typically $1 - $2 per enclosure). I am constantly looking for lower cost alternative sources for my materials but with my low volumes I don't get much of a break. The price increase will go into effect March 5th, 2016. Also, due to the recent USPS price increases in January of this year, I can no longer offer the flat $8.50 domestic shipping charge. I have restructured the shipping charges based on weight and zip code zone (by state). In the zones closest to my location (MI), the rates have actually dropped from the $8.50 flat fee for single enclosure orders. Obviously, the farther out from my location, the higher the cost. PayPal is now allowing the use of First Class mail for packages 16 oz or less. Most of my enclosures, with packaging, weigh in around the 15 - 16 oz mark, so I will be implementing this as a shipping option for single enclosure orders in the near future. This will be a lower cost option compared to the current Priority Mail option. Please contact me for a direct shipping quote for 5 or more enclosures. And as always, contact me for a quote for all international and custom orders. I have already implemented the Priority Mail changes to the site, but I will honor the old enclosure prices for another week. Thanks for the bandwidth. 73, Dave W8FGU Website: http://www.w8fgu.com email: dave at w8fgu dot com From gm4jjj at yahoo.co.uk Sat Feb 27 13:59:35 2016 From: gm4jjj at yahoo.co.uk (David Anderson) Date: Sat, 27 Feb 2016 18:59:35 +0000 Subject: [Elecraft] PX3 noise generated on KX3-2M In-Reply-To: <56D1E8CD.4030509@sonic.net> References: <8510CA90-8DEE-47DF-9DE8-B480DF3CE491@yahoo.co.uk> <56CCB512.10702@audiosystemsgroup.com> <56D135BA.1030201@sonic.net> <5A9135B7-DBF8-4F55-B3ED-E787E5ED3EAC@yahoo.co.uk> <56D1E8CD.4030509@sonic.net> Message-ID: <74B73BCA-9B8A-48EE-A997-F207BF5C6989@yahoo.co.uk> That is how I fixed my problem then, I have connected the real common on the top of the socket to the flange which is connected to the case. I used a piece of copper tape as shown in last email photo. This stops the connection between the flange (case) and the common on the board being reliant on the plug being a tight fit in the barrel. It all makes sense now. Sorry if I had confused the situation with my description written from memory, but I did send photos clearly showing what I had done. ;-) I was adamant that this fixed a problem for me with radiated crud on 2m, especially annoying as it could be intermittent depending on how much pressure was applied sideways to the plug. This type of connector is used in other pieces of gear, like the KX3, is there a similar pin 1 type problem as a result of the same thing I wonder Alan? I am sure you folks at Elecraft will come up with a more elegant solution than I did. :-) 73 from David GM4JJJ > On 27 Feb 2016, at 18:19, Alan wrote: > > However I did find out something that was news to me. I had to remove the power supply board from the PX3 and do some more ohmmeter measurements to discover it. It turns out that the metal body of the connector that screws to the panel is not connected to its ground pin! In other words, there is no electrical connection between the side panel and the ground pin (PCB ground plane) when the power plug is not inserted. > > When the plug is inserted, the mounting flange and the ground pin are connected only through the plug's outer sleeve. That solves the mystery of why wiggling the plug caused the radiated noise to go up and down. If the plug's sleeve does not make good contact with the connector flange, then there is a "pin 1" problem because the sleeve is grounded only via the PC board, which has a long return path to chassis ground.

The website has a list of the devices that are known to work. You will need to make sure the device has USB hosting enabled. Some devices do not, and some wireless carriers apparently cripple this feature in their devices. You will need the Elecraft KXUSB cable and an aftermarket OTG adapter; the latter is available on Amazon and I've used examples from two different vendors.? The 2013 Nexus 7 is a couple of generations old, but shows no sign of being limiting in processing speed. The KX3 is doing the heavy lifting: decoding CW, RTTY, and PSK and generating I/Q outputs. The app is just displaying the decoded text, waterfall, and spectrum, and sending commands to the KX3. The tablet setup also works fine with the KX3, PX3, and KXPA100 all hooked up in series, although decoding needs to be turned off in the PX3.? I find the 7" tablet size to be the perfect compromise; small enough for 24-7 portability, not too small to read and use, and big enough to use the full complement of 20 programmable macro keys. You may find a smaller device to be much less convenient to use.?

See if that "330" isn't really "33G". If so, it is the 47pF that you seek. If it is marked "470J" then it is for certain the 47pF. Sort your capacitors. You should have 4 33pF and 4 47pF. Once you have them all sorted and can compare the markings, it should become obvious. The manual may show a disc type, but the type of capacitors has changed to mono in many cases. The color of the capacitors has changed over time too. One thing I can tell you is that you have a 2.2pF capacitor that is now labeled "229" - the '9' indicting that the decimal should be moved to the left by one place (9 is a negative 1). That 2.2pF capacitor used to be a disc ceramic too, and is likely shown that way in the manual. Sorry that this is confusing, but component procurement is getting more and more difficult as the industry moves to surface mount, and the sources of thru hole components is drying up. 73, Don W3FPR On 2/27/2016 12:03 PM, Rick A. wrote: > Hi all, I am working on assembling my K2 and for component C73, 47uf, > all I have in my kit is a yellow colored cap that has 470 on one side > & 330 on the other side.

That will be very useful. Now all I will need is a save/restore function for the center frequency and the span. I use fixed mode and have set up those parameters differently for each band. For example, on 18 MHz I have the center set to 18.084 and the span to 32 kHz. That gives me a fixed display of 18.068 to 18.100. If I had #RCF and save/restore, I could make one macro to save and drill down to the pileup, and another to restore to the normal setting. The #RCF would allow me to restore the center, as long as I didn't change VFO A! But I often fiddle with it.

My own experiments have used WinE and VirtualBox on Raspbian Jessie with the newer quad-core RPi model 2. App performance has been remarkably good, with Windows 10 on VirtualBox showing the most promise. The stumbling block always seems to be getting CAT working with Windows serial ports talking through the Linux /dev/tty* devices. Unfortunately, this pursuit is at the bottom of a long list of programming projects and I am not likely to make further progress anytime soon. But I am interested in the topic and look forward to hearing about your findings. -larry (K8UT) -----Original Message----- From: Jerry Moore Sent: Saturday, February 27, 2016 12:02 PM To: jim at audiosystemsgroup.com ; elecraft at mailman.qth.net Subject: Re: [Elecraft] Logging Programs Any Of these run natively und r linux?

I'd go with his advice that 400 Hz is right for RTTY. He's not the only one who thinks so. So do W0YK (another winning RTTY contester) and G3YYD, the author of 2Tone, an excellent RTTY decoder. Switch to narrower IF only when the QRM gets really bad. And so do I.

SSB or a soundcard data mode? For SSB, did you first set Compression to zero? If not, you should do that (Data modes do that automatically for you). For SSB, you want 5 to 7 bars, but for DATA modes, you want 4 bars solid with the 5th bar flashing. Set the soundcard output sliders to about 2/3 of max and adjust the rest with the MIC Gain control (controlling LINE IN). A few checks - do you have MIC + LINE set in the menu? If so, turn it off. Is there a possibility of RF feedback? Even if you think NO, please check it - set the K3S into TX TEST and no RF will be produced but all the other TX controls will work as normal. If it turns out to be RF feedback, you have a different problem to solve. That is usually most effectively controlled first by having good common mode chokes at your antenna feedpoint and possibly another at the shack entry point. See the RFI documents of Jim Brown K9YC for information on effective common mode chokes. Yes, some "baluns" claim to be good common mode chokes, but others are woefully lacking. Keeping the RF out of the shack is always the best approach, but if you have a difficult situation such as an antenna close to the shack, you will receive direct RF in the shack area, and then the best cure is ferrite material on your connecting cables. 73, Don W3FPR On 2/27/2016 5:17 PM, Sid Frissell wrote: > Howdy > Been using my K3s (S/N 10462) for JT-65/JT-9 and am struggling with setting the ALC.

You can see from the answers that not one logging program fits all. It very much is a matter of taste. It should be very easy to move your log from any one logging system to another, so you dont have to worry about missing logged QSOs. I have used the free version HRD for many years and it fits my needs. I use another logging system (Ham Quicklog) on this iPAD (when operating RC from the iPAD) and from time to time I "synchronize" the HRD and Ham Quicklog logs. Takes a few minutes but no sweat.

You cannot reliably check the inductor relays without removing one lead of the inductors. Do that first. Then in menu ATU CLP you should have continuity through all the inductor relays. L0 is the state where no inductors are selected, similarly, C0 is the state where no capacitors are selected. I can draw no conclusions from the relative power output between 40 and 20 meters. You will have to lift one lead of all the inductors and see if there is end to end (input to output) conductivity. You should be able to do that with a DC ohmmeter. If you do not have end to end continuity, you can check each of the relays that short out the inductors to see which is the problematic one. 73, Don W3FPR On 2/27/2016 9:53 PM, Michael via Elecraft wrote: > Still have not figured out what's wrong with my newly built K1 w/ ATU. > > For some reason everything is fine on the 40 M band but once I switch to 20 > M the power output > drops way down.

I became aware of the program as someone close to me did tech support prior to becoming an SK. It does have a healthy yahoogroup for questions. They make no bones about it NOT being a contest software program. Otherwise, it does virtually everything a logging software needs to do. For contesting, I use the W3FJP software, as it is easy to use. My goal is to learn N1MM, as that is what I believe to be the de facto contest program. I then export the contest log as an ADIF file, and import it into logger 32 which has my main log. Both will do Cabrillo format which is the format in which contest files are generally submitted.

There is an addendum to Page 4 which reads: After installing the K3EXREF module, you must enable it in the K3 menu before it can be used if your K3 is equipped with MCU firmware 4.57 or later. Enable the K3EXREF module as follows: * Turn the K3 on. Confirm that TECH mode is on (CONFIG:TECH MD On). * Turn the VFO B knob to locate the CONFIG:REF CAL menu entry. * Tap the REV / 2 switch and note that the VFO B display flashes between XREF IN (K3EXREF module active) and XREF OUT (K3EXREF module disabled). Tap the REV /2 switch so that XREF IN is displayed. Ii is important to disable the module in the menu if you remove the K3EXREF module in the future. http://www.elecraft.com/manual/E740156E%20K3EXREF%20Errata%20A2-5.pdf I hope that helps. 73 de David G4DMP In a recent message, Tighe Kuykendall writes >I picked up the Leo Bodnar frequency reference and a K3EXREF board >after reading a couple of threads here.

It should give you a general guideline on what to initially adjust, look for, and set up for your K3 / computer / software package. My specifics are a KX3/KXPA100 with Windows 10, no rig interface (kx3 connects to computer directly via audio cables and usb cables) and WJST-X. Antenna is a 40 meter extended double zepp fed with open wire feed for multiband operation. I make all my JT contacts in DATA mode and not SSB mode, and while I can and have made data contacts in SSB mode, I find it much less worrysome from an ALC settings standpoint to use DATA mode for digital contacts. I make hundreds of JT contacts on the bands, 40-15 meters mostly. First, make sure you have your computer and JT software set up to control rig keying correctly. It is important to make sure the computer, JT software and the K3 all talk together properly and perform as expected with regard to rig keying first. In WSJT-X, I use cat control to key the radio. I do not use VOX. On the radio side, in DATA mode, I have the mic gain on my KX3 at 25. This is generally where I run the mic gain when I make SSB contacts and should serve as a good initial starting point for you. Be aware that, at least on the KX3, too high of a mic gain setting will show no ALC indication and can give erratic rig performance regard to TX output stability (what I would call as ?power hunting??a cycling or slow oscillation of ALC indication and indicated power output as the KX3 tries to maintain a stable output). I would imagine the K3 to be similar. Generally speaking, err on the low side of mic gain settings as you can easily make ALC fine tuning adjustments for higher ALC within the JT software later. Once the mic gain on the radio is set where you have solid radio keying and power output performance, do not touch it again in normal JT operation. You can always come back later after performing the below rough adjustments and make any minor settings for optimal performance later. As a general guide, once the mic gain is set for good solid operation, you never touch it again. On the computer side, specifically with regard to the audio slider settings in Windows, I have the Playback device level set at 50 (midscale). If your soundcard in your computer allows for advanced settings such as audio equalization or audio effects, make sure all of these are turned off. On the Recording side, it too is set for midscale or 50. Make sure you have any special audio effects on the recording side turned off. Pay special attention to any mic gain or boost settings if your soundcard has these features and ensure they are all turned off. Once set within Windows, I do not touch the audio slider settings again. There is a lot of variation here with regard to proper audio settings you will end up within Windows due to hundreds of different possible audio cards found in various computers and the final mic gain setting you choose on the K3, but generally speaking, you are looking for non-overdriven audio input as indicted by the ALC display on the K3 with the mic gain set as described above. In your JT software, you should have some sort of audio sliders that do basically the same thing as the Windows sliders settings. In WSTJ-X, there are two controls you will use to make the necessary audio fine tuning adjustments. Set the RX audio input slider so that you have acceptable RX audio levels for good decode. In WSJT-X, this control can be found on the main program window, on the far left hand side of the display. I find the best decoding performance to be when the RX audio slider is adjusted so that the software displays a levels of approximately 25-30 dB in RX mode with no stations transmitting (ie, monitoring a quiet band). This is approximately midscale on the visual display. Once the RX level is set, you can then adjust your waterfall visual display so that you have whatever visual settings you prefer to see (all of these visual sliders are at the bottom of the WSJT-X Wide Graph window.) The takeaway here is to have the AF gain settings on the rig and recording audio sliders within Windows to give approximately 30db of indication within WSJT-X. Fine tuning here can be done within WSJT-X or even with the AF gain control on the K3 if need be. With regard to TX audio levels in WSJT-X, the slider you want to adjust for proper ALC indication on the K3 is the Pwr slider, found on the far right hand side of the main program window. Set the Pwr slider to be approximately midscale initially. Key up the K3 with the TUNE function within WJST-X and while transmitting, slide the slider using your mouse wheel (don?t drag the slider by clicking and holding with the mouse), up or down, to obtain 4 solid bars as displayed on the K3. It wont take much in the way of adjusting the Pwr slider to obtain the correct ALC indication if the mic gain on the K3 and the Windows audio settings are correct. Hovering your mouse over the power slider should show you WJST-X?s TX digital gain level. For my setup, I show approximately -20db, but this exact value will be different for your specific rig settings and computer audio settings. I generally like to see the Pwr slider about midway of the scale. This gives you ample adjustment, up or down, as needed to get the ALC as displayed on the K3 correct. The general takeaway at this step is that you want your K3 mic gain and Windows playback audio sliders set so that you use approximately a midscale level on the Pwr slider in WSJT-X in order to give a good ALC indication on the K3. After the initial adjustments described above, make all of your fine tuning ALC settings for the K3 through WSJT-X. Don?t touch the mic gain setting on the K3 or touch the Windows audio sliders. The Pwr slider in the WSJT-X software has a much better fine tuning control of the ALC settings displayed on the K3 than you can obtain with either the radio or within Windows. As you change bands, and even as you change specific audio TX frequencies within the waterfall display, monitor the ALC display on the K3 and use the WJST Pwr slider to make any minor fine tuning adjustments for proper indication of ALC. Once its all set correctly, it only takes one or two mousewheel indent rolls, up or down, to bring ALC into the correct level. The main thing to takeaway with this approach of ALC control is that you have better fine tune level of control of ALC indication using the WSJT Pwr slider as the WSJT?s slider is not nearly as sensitive and touchy as trying to control ALC via the KX3?s, (and likely the K3?s) mic gain. You?ll have better fine adjusting of ALC control overall using this approach. One last general comment. I know the instructions on setting the ALC level for proper transmit in DATA mode say to look for 4 solid bars and the 5th bar to be flickering. In my experience in operating JT modes heavily for several months, I have found the best performance in making contacts is to set the ALC for 4 solid bars and not worry about a flickering 5th bar. If I happen to see the 5th bar flickering, that?s fine and I don?t worry about adjusting it lower, but I always shoot for at least 4 solid bars and find it to be a solid performing setting when making JT contacts. When set this way, I have just the occasional flicker of a 5th ALC bar...sometimes I may see an occasional flicker the 5th bar, but most of the time I don?t see any 5th bar flicker. If I have been playing around with rig settings or other computer settings and I need to get things back to a stable value for JT operation, its always done first by making sure I have the general mic gain and windows audio slider set as I outlined above. I make any necessary final ALC adjustments with the Pwr slider in WSJT. It never takes more than a mousewheel roll one way or another to bring it right back where I want it. Hope this helps and here?s hoping to see you on the waterfall! 73 Dave, N5XL Sent from Mail for Windows 10 From r.tristani at gmail.com Sun Feb 28 10:04:34 2016 From: r.tristani at gmail.com (Tristani Ramon) Date: Sun, 28 Feb 2016 10:04:34 -0500 Subject: [Elecraft] ALC adjustment on K3S In-Reply-To: References: Message-ID: <5A7A6280-AA47-4A01-B8BD-2E6E23A0757D@gmail.com> Dave: This is a great post.

I've mentioned it here in the past more in reference to the built-in sound card super sensitivity affecting VOX setup. The best I've done is to go into the Windows Sound setup and reduce the output (speaker) gain to about -30 dB. This will reduce the touchiness of the Mic (Line Level). Still I find it near impossible to set up for "flickering" bars, however. This isn't an issue with my old K3 using the computer sound card and analog audio in and out of the K3. Progress?

So do not change them, they need to be configured as needed on the remote side. For the mini there's no selection. The front panel mic socket is enabled as long as you do not plug-in anything into the left mic socket. As soon as you do it will disable the front panel socket and take audio from the 3,5 mm plug. Internal to the K3/0 mini is a jumper that sets mic bias for the 3,5 mm socket. Maybe you need to check if it is set accordingly. Mine was, I had to disable it to allow me using my non-electret mic there. 73, Olli - DH8BQA Contest, DX & radio projects: http://www.dh8bqa.de Am 27.02.2016 um 20:16 schrieb jlbates4: > I'm beyond frustrated... > > Situation: I've got a K3/0 attached to Remote Rig boxes to my K3 in the > shack.

So far I've been pretty impressed with it's ham radio capabilities. FLDIGI was pretty easy to get running though I haven't progressed to the USB hookup on my K3S yet (a few other programs to get running first). In the Logging Programs thread, CQRLOG was mentioned as a good Linux based logging program and I have successfully gotten it running on the Pi 2. It is a little tricky to install and there is at least one depencency (mysql) that isn't in the CQRLOG package so you're on your own finding and installing that first. There are others out there that apparently have some version of the RPi running as a K3/KX3 control computer, so this is really nothing new, just a reiteration of the fact it can be done and the little single board Linux box seems to be up to the task. I'd look forward to seeing how someone else has done the K3S USB interface (off line please to avoid Eric's wrath for too much clutter on the reflector) and as I get time I'll continue the attempt myself. As far as I have gotten, everything appears to work well and using WiFi, I have a stable internet connection which is absolutely necessary to keep frustration to a minimum when looking for and installing programs on the Pi 2.

Message-ID: <56D33B0E.2010808@snet.net> The manual for the K3/0 says: "It uses its internal speaker and front headphone jack for receive audio, and its front microphone connector for your mic input." In other words you need to use the front mike connector on the K3/0. The mike connector on the back of the K3/0 is actually an output to the RemoteRig box. This is different than the back of your K3/10 K3/100 radio, where it is an input. You need the special E85051 (or homemade equivalent) cable that connects the K3/0 "SPKRS" and "PTT IN" to the RRC1258 "AUX/MIC" jack. BTW, the "PTT IN" on the K3/0 is actually a PTT output from the K3/0 to the RRC1258. You may be able to make a direct connection to the RRC1258 "AUX/MIC" for your headset. I've never done this, but it may be possible. The HM2 mike is an Electret that needs bias on. Both Heils are probably Dynamic and need bias off. You'll have to check the Heil literature. I don't know how bias is controlled in the K3/0 so I don't know how bias on/off woks at the K3/0 but it's worth mentioning as a possible problem. If you are using the E850511 that came from Elecraft, there is a possibility of a "digital noise" problem. The pairs used for mike audio are split between two pairs, causing an imbalance. This may or may not show up in your K3/0. There is also a small noise problem in the E980207 speaker cable that goes between the K3/0 and the RRC1258. I fixed that with isolation transformers. 73, Joe, K1ike From kevinr at coho.net Sun Feb 28 14:20:47 2016 From: kevinr at coho.net (kevinr at coho.net) Date: Sun, 28 Feb 2016 11:20:47 -0800 Subject: [Elecraft] Elecraft CW message Message-ID: <56D3488F.6030308@coho.net> Good Morning, Earlier this week I lost the transmit function of my K3 during a contact. In a subsequent email message I was informed the K3 went off the air like the house had lost power. Such was not the case; I was copying just fine.

Conditions being what they are it will be difficult to tell if the K2 is working or not. If this does not succeed I will try one of my other radios next week. None of them had heard of using PIN diodes for T/R switching so they drive me crazy with their relays rattling. Currently the weather is trying to switch from winter to spring. Not all in one day though, there are still high winds and rain. Antenna repair will have to wait for a less windy week.

Some are RF quiet; some are not. There are three potential sources of RF leakage I have personally experienced: 1) Variable speed inducer motor - this is a small motor used on higher efficiency furnaces to provide draft air to the combustion changer. Some manufacturers have a kit that MAY reduce or eliminate the noise from this motor. 2) Variable speed blower motor - this is the large motor used to move air through the heat exchanger and into the duct system. I have a 3/4 HP variable speed motor in one system that is dead quiet; I also have a 1 HP version of the same motor from the same motor manufacturer in another system that is very noisy. The engineer that designed the motor confirmed that in the 1HP version it was difficult to manage RFI emissions. 3) Variable speed condenser fan motor - this is the motor on the outside compressor/condenser unit. Some manufacturers use a variable speed motor running at a fixed speed for this application. The one I have is very noisy. --- Chuck, AE4CW -----Original Message----- From: John K7JLT [mailto:k7jltextra at gmail.com] Sent: Saturday, February 27, 2016 18:03 To: Mailman Subject: [Elecraft] Furnace RF Noise I am blessed with a low noise level that matches my K3 and need to replace my gas furnace without degrading my low noise level.

Further, I had intended on installing the MFJ 1164B AC Line RFI Filter (a 4-plug rugged RFI filter with a separate external ground), so I plugged it into a separate AC circuit and that combination made the AEX happy. 500 watts no problem. Like so many people, I have several Mac computers, two printers, an audio system, lamps, misc. gear all in proximity to the K3S and KPA500, and even though I do run a separate AC line for the ham gear, the non-ham gear is powered with a hodgepodge of power strips and extension cords. Clearly I need to get those in order also. So, case closed ? happy to advise anyone who might have the same issue on my steps to resolve it. Back to my Oscar party. :?)

Great tip -- totally forgot the "tap" "2" step. My EXREF had quit some time ago and checking 10-MHz sources all tested good so I figured my "beta test" unit had given it up. Too busy to investigate further. It stopped after I had a firmware glitch so now guessing that shut off the EXREF. So I did the tap-2 and REF CAL showed no asterisk - uh oh. I changed 10-MHz source (I have a 4-way distribution amp) and still nothing. So "utilizing my trouble shooting skills" I decided to check the coax and found the sma connector not fully tightened at the K3. About 1/2 turn is all it took and REF * CAL with asterisk blinking and the 49.380.000 oscillator is shifting upward again compensating TCXO drift (mine tops out at about 49.380.072). Its my belief the upward drift is from initial radio warm-up and once it reaches operating temp** is reached its fairly stable varying only a few Hz. My Beta Tests indicate my EXREF holds my K3/10 within 2-Hz at 28-MHz (which is my IF for transverter operation). I have a mw frequency counter (with internal TCXO) for checking and also a Rubidium oscillator which I use as my Frequency standard. Counter TCXO is never off 1-Hz from the Rb source. The OCXO requires adjustment about 2 times per year for long-term drift. **NOTE: I have a K3/10 so the 10w amp doesn't produce a lot of heat. When I operate in transverter mode the K3 operates at 1mw with no extra heat in Tx. If you have a K3/100 that could be different when on HF/6m. I did find one of my four port distribution amp has no output (BNC appears loose so probably has broke off the wire inside). I have a 432 and 1296 transverter that both use a synth-PLL LO locked to 10-MHz. My source is a $45 e-bay Russian surplus OCXO. My Point: Beware that sma must be properly tight to have good contact. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From sidfrissell at gmail.com Sun Feb 28 21:23:10 2016 From: sidfrissell at gmail.com (Sid Frissell) Date: Sun, 28 Feb 2016 19:23:10 -0700 Subject: [Elecraft] Setting ALC for JT-65/jt-9 Message-ID: <15A75CC4-F5F6-4A92-9686-6682B76FEF8A@gmail.com> Well, let me do a final summary of what I learned from many kind fellow hams here and via personal eMail. There are two schools of thought on how you accomplish four solid bars and a fifth blinking (ALC meter). 1. Several people sent me fairly long, complex discussions of the problem with final recommendations to use the Mic Gain control to control old "blinky 5". Well meaning but not helpful as that was exactly what I was complaining about. That control is irritatingly sensitive!, especially for us older gentlemen. 2. The alternative approach was very well-explained by Ian, N8IK (short form) and Dave, N5XL (long form). After very usefuL steps re. Windows audio sliders etc, they both set radio audio with mic gain level in the Menu. Then (trumpets and drum rolls here) the final adjustment of Blinky 5 was done with the Power Slider in WSIT-X. Wow. That slider seems much less sensitive and does the job nicely. I will wrap up this thread with a cheer and many thanks to you who shared your knowledge. This group rocks!

To prove that, I removed every control and sensor line from the furnace enclosure and "hot-wired" the internal control board to run the blower at full speed. Thus isolated, the RFI from the blower motor was completely contained and not visible on the spectrum display nor audible on the radio. So, the solution is that EVERY wire that exits the furnace enclosure must by filtered or bypassed. Since all these lines carry low-voltage DC, a simple bypass capacitor on each line will work. --- Chuck, AE4CW -----Original Message----- From: Jim Bolit [mailto:jbollit at outlook.com] Sent: Monday, February 29, 2016 10:28 To: 'Chuck Catledge' ; 'John K7JLT' ; 'Mailman' Subject: RE: [Elecraft] Furnace RF Noise Carrier air conditioning offers an add on filter IF the consumer complains.

I'm also planning to try getting time information from the Bodnar device into a Raspberry Pi.

I have 5 Pole 2.7s in both receivers, but multiple 8 Pole narrower filters as well as a 5 pole 200Hz that always was hard to listen to. I read through the manual and Fred?s excellent K3 book and found that higher gain was not recommended. I had 4dB or more gain on a few filters especially narrow CW. I decided to experiment with lower gain settings. When I reduced the gain to 2-3 dB the ?ringing? in the narrow filters reduced a LOT! That coupled with the new Synths has made the old K3 come to life all over again. It is truly amazing in pileups. Individual signals just pop out of the mess. Thanks to Howard at Elecraft for digging up old invoices with factory mods and updates. And thanks to Elecraft for engineering such an amazing upgrade to an old radio!

Do you have a stereo 1/4 inch phone plug that has nothing connected to it? If not, can you borrow one? Plug it into the jack and see if you still get the ERR KEY. If not, the K3 is OK and the problem is with the paddles, the cable or the plug.

Message-ID: Dear Group, I think I might have to send my PX3 back to Elecraft, but thought I would post and ask here first: My PX3 seems to be inhabited by gremlins. I turned it on today (haven't used it in a while) only to find that nothing is functioning as it should. The power is not coming on with the KX3, and the knob isn't functioning properly. I went ahead and put the latest firmware in, and for a few minutes it seemed to work. When I turned the knob I could get it to make some adjustments (except the markers) and cycle through menu options. When I tried to cycle the power, it did not follow the KX3, so I turned it off via the power switch, but when turning it back on again, nothing worked. I did a factory reset: hold LABELS and cycle the power, but no joy. Never been dropped or wet. It's been in my carry bag since last fall.

My design team in the Philippines did a variable speed power supply (4-6 kW range) where we also had to design a simple common and differential mode AC filter that was an available option if any "ham guys" (it was referred to as the "ham guys" filter in our communications with the customer) raised a noise issue with the power supply.

To prove that, I removed every control and sensor line from the furnace enclosure and "hot-wired" the internal control board to run the blower at full speed. Thus isolated, the RFI from the blower motor was completely contained and not visible on the spectrum display nor audible on the radio. So, the solution is that EVERY wire that exits the furnace enclosure must by filtered or bypassed. Since all these lines carry low-voltage DC, a simple bypass capacitor on each line will work. --- Chuck, AE4CW -----Original Message----- From: Jim Bolit [mailto:jbollit at outlook.com] Sent: Monday, February 29, 2016 10:28 To: 'Chuck Catledge' ; 'John K7JLT' ; 'Mailman' Subject: RE: [Elecraft] Furnace RF Noise Carrier air conditioning offers an add on filter IF the consumer complains.

Some are RF quiet; some are not. There are three potential sources of RF leakage I have personally experienced: 1) Variable speed inducer motor - this is a small motor used on higher efficiency furnaces to provide draft air to the combustion changer. Some manufacturers have a kit that MAY reduce or eliminate the noise from this motor. 2) Variable speed blower motor - this is the large motor used to move air through the heat exchanger and into the duct system. I have a 3/4 HP variable speed motor in one system that is dead quiet; I also have a 1 HP version of the same motor from the same motor manufacturer in another system that is very noisy. The engineer that designed the motor confirmed that in the 1HP version it was difficult to manage RFI emissions. 3) Variable speed condenser fan motor - this is the motor on the outside compressor/condenser unit. Some manufacturers use a variable speed motor running at a fixed speed for this application. The one I have is very noisy. --- Chuck, AE4CW -----Original Message----- From: John K7JLT [mailto:k7jltextra at gmail.com] Sent: Saturday, February 27, 2016 18:03 To: Mailman Subject: [Elecraft] Furnace RF Noise I am blessed with a low noise level that matches my K3 and need to replace my gas furnace without degrading my low noise level.

It?s had a few mods/upgrades along the way and its firmware is current. Last Field Day 2015 at W5YA, the K3?s LPA failed after a close lightning strike. I was able to successfully repair the LPA replacing both discrete and SMD components. Performed a Pout calibration using the K3 Utility program afterward and it passed. My 9500 amplifier (driven by the K3) has had a few instances of a high plate current faults since new in December 2010. These faults had been infrequent enough to ignore. More recently though the problems have been occurring more often. Swapping the tube did not help nor did careful inspection inside the amplifier reveal anything. Evidence that the problem is related to the K3 and not the amplifier presented itself by accident a few days ago. I had the K3?s output set to 40w and the Alpha was off. I inadvertently bumped the key and noted an instantaneous output of 54w on the Powermaster II wattmeter. A few more dits, and the power output settled back to 40w. Hmmm? if the amplifier had been in line, the K3?s drive set for full legal limit and a first dit resulted in an additional 30% drive, a high plate current fault might certainly happen. This morning I was using the KPA500 amp with my K3?s power set to 28 watts. After an early AM CW fix I left the station on, walked away and came back in a few hours hours. On first dit the KPA?s instantaneous power showed 650w on the Powermaster II and illuminated a red LED on the KPA500, then settled back down to <500w. OK, so it IS the K3 causing the problem BUT the power output spikes occur very infrequently. It?s difficult to nail down the cause or even the conditions under which the problem is most likely to occur. Reading the archives, others have had power spike issues over the years. Is there a known fix? I?ve looked briefly at Elecraft?s alerts and mods but nothing jumps out. 73, John K1JD Santa Fe, NM From n7tb at comcast.net Mon Feb 29 15:36:13 2016 From: n7tb at comcast.net (Terry Brown) Date: Mon, 29 Feb 2016 12:36:13 -0800 Subject: [Elecraft] Final Thoughts on Logging Software Message-ID: <000301d17330$da85eed0$8f91cc70$@comcast.net> Hello All Elecraft Users, Several days ago I started a thread asking for recommendations for logging software. I later reported that I was in the process of deciding what way I wanted to go. I thought it would be helpful to the group to share what I found after a day or so reviewing, installing and comparing logging programs that interface with the KX3, with the understanding that logging software is a very personal preference. I had been using LOGic9 which I recently upgraded to after about a 9 year hiatus from amateur radio. I had been using LOGic8 for years. With the upgrade, I was getting crashes and at one point the program locked up. What I found was that all the logging programs that were suggested were very good and would do most of the things any ham would want. I spent a great deal of time with the DX Suite of programs and found them very thorough but a bit of learning curve ahead of me. When I imported my log data, it threw out many of them. I was running Amateur Contact Log and was amazed to find that when the spotting window was opened, I could click on the spot and my radio would go to that. (later I found other programs, including LOGic, did as well). I was about to switch but found that the QTH field was not in that program. I finally decided to go back to the new LOGic documentation and re-read it, because I had not done that for 9 years. You would think that with a Ph.D., I would have done that first, but no, I didn't think I "needed" to! Long story short, I found that LOGic9 was an amazingly powerful yet customizable all-in-one logging, contesting, and awards package. Regarding changing my radio frequency to the spot frequency, LOGic 9 did it extremely well. In fact, i have a friend in Rarotonga who is on periodically. I found I could set his call in the filter, let LOGic run recording spots and if his call was recorded, LOGic would send me an email telling me he was on. It will even give you an audible announcement, or send email, if a contact comes up that one might need for any of the many awards that one might be going for. Logic tracks all the awards that are most common, and you can create your own awards that LOGic will track as well. Having an audible notification is helpful if you are doing other things in your shack. There are multiple spotting sites that one can configure to run with LOGic. The logging form is totally customizable with preselected fields with the capability of creating your own custom ones as well. I run LOGic on a computer that is on 24/7 for a weather station I have, so keeping LOGic running in the background will be great for giving me notifications. Contesting forms are included that are fully customizable, and I don't think you have to download your contacts into your regular database at the end of a contest, but can have them automatically recorded there if you desire. As one would expect, LOGic has full capability to interface with LOTW and download contest logs. I found LOGic was probably the most all-inclusive, customizable software I came across, and I looked at a lot. I like the fact that when I am using my laptop portable, I can copy my log, then when I go to my main computer, it will import, if I select it, only the QSO's that are not already in the log. Going from one computer to another is very easy. Anyway, most of my problems were self-imposed. If I had spent some time with the manual (and the program itself has extensive and thorough help available) I would have avoided a lot of my frustrations and crashes. The software is so customizable, that I had created some fields without the proper properties. When I reread the manual, I realized again why I chose LOGic years ago. I am now happy using LOGic9 and enjoying all its power and flexibility. It is not free, however, it is $129.00. With the amount of time I spend in my shack, and the amount of money I paid for my wonderful Elecraft equipment, it was a small investment in the greater scheme of things. I believe my upgrade was less than $90. With a registration, you get free updates for a year. It has great importing flexibility so you can import your logs from other logging software to see how it works in LOGic. There is a free 30 day trial you can use to try it out if you are interested. I understand from the author that they are still working on polishing up the interface software for the K3 (KX3), occasionally there are issues. Things are running well for me now. The author gave me detailed instructions for using OmniRig with the software if I have problems in the future. I suspect any remaining issues will be resolved shortly anyway. I hope these ramblings are useful for others who may be looking to start using or change their logging software. For sure, logging software is a personal preference, and it was clear to me from all the direct emails I received and from those on the group, that most people are very happy with the software they are using. Sometimes it is good to take a fresh look at what is out there. With the log importing capabilities of most packages, going from one to the other is pretty easy to do "test runs." If I had not had problems, I never would have taken the time to look at the various products out there. I am glad I took the time to do it. Others might find it useful to take some time to do the same.

Two 1/2 inch beads on each line with 3 turns through each bead as close to the cabinet exit as possible. Took the noise from S7 to my usual -125 dBm band noise level. No need for a line filter. Remember that the number of turns required will depend on the frequency(ies) where there is RFI. 3 turns peaks more or less around 10M. If you have noise below that, you'll want more turns (a lot more for the lower bands like 80 and 40). 73, Jim K9YC From kl7uw at acsalaska.net Mon Feb 29 20:15:47 2016 From: kl7uw at acsalaska.net (Edward R Cole) Date: Mon, 29 Feb 2016 16:15:47 -0900 Subject: [Elecraft] DEMI transverter sales Message-ID: <201603010115.u211FlSh010128@mail42c28.carrierzone.com> Sam, OK, and thanks for the clarification. I was notified last week that they would no longer sell me kits for resale as assembled units (ergo - I am out of business building DEMI kits). Apparently that was a condition of the subcontract made with whomever is now building VHF/UHF transverters (it does not necessarily mean the subcontractor is making ALL DEMI transverters - guessing its just 50-MHz thru 432-MHz). I discussed buying out the VHF/UHF DEMI transverter line from DEMI about a year ago when they were wanting to shed the work load to be able to focus more on the mw end of the business. I decided the financial cost/risk was too high for me plus work load more than I wanted (one person). Since DEMI has not made a public announcement, I was in a predicament what words to use (if any). Apparently they have no problem with you making this public. On my website I removed all my text pertaining to building DEMI kits and replaced it with a vague statement about "a change of business at Down East Microwave". Your clarification answers a question that I had so DEMI will continue to handle all sales, just not fabrication of transverters (VHF/UHF). I will suppose DEMI will continue to build in-house the mw line (>902 MHz). My reply to Steve's e-mail has not been returned. I have long supported and promoted DEMI products (long before I began selling assembled kits). And I will maintain a link to their website for those that may seek me to build a kit. Steve and Sandra were very kind to permit me to run my "little" kit building "business". In fact I feel my efforts helped them maintain a customer base that might have gone to competition (they still sold the kits thru me). I sold at the same price so I would not be "competing" on price...only reason I got customers was delivery speed. It was fun and gave me a little pin money for ham radio. Now it is over. I have moved onto other products. Thought this was better said direct than on the Elecraft reflector. 73, Ed - KL7UW BTW do you know the disposition of the DEMI Flex amplifiers? The catalog no longer shows them. I had an inquiry for one from a Flex6700 owner. Date: Mon, 29 Feb 2016 15:48:49 -0500 From: "Sam Carson" To: Subject: Re: [Elecraft] Best Place to Sell Equipment?

Both the PX3 and the KXPA100 act like they have a mind of their own. The system slowly rights itself... first KXPA100 comes on and cycles with the KX3, then the PX3 just starts working rando. Once all three are up and talking to each other, the system is good until the next time I do a complete power down and disconnect the antennas. Before you ask, I have tried to reseat all cables, I have checked to make sure PA is enabled in menu, and I have pushed the power on switch on the PX3. I have also switched to different USB dongles (I have 3 Elecraft KXUSB units). My solution is not to completely shut the station down unless I have to because of lightning.
