Message-ID: <201509010830.t818UDED006697@mail42c28.carrierzone.com> This thread is probably just about over- I ship using USPS Priority Mail almost exclusively. Small box = $5.25* Medium box = $11.30* Large box = $15.80* *If you pay online - a bit more if you pay at the PO Priority Mail is 2-day delivery which translates to 3-day in Alaska (it gets to the Anchorage Airport Sort Center in 2-days and is delivered by truck 180mi to my PO the next day). But I allow up to 5-days delivery time for Priority Mail out of AK for my customers. Parcel Post takes a min of 18-days and usually 20-days. Overnite Express Letter - takes two days! UPS/Fedex 2-day delivery for the same item in AK is about 2x to 3x as expensive (of course shipping in/out of AK requires using a NASA Launch to the nearest planet). Guess what it still takes 3-days with them, too! I ship world-wide using flat-rate International Priority Mail (even to Canada which costs more than within the 50-states). Medium box to UK or EU is $76.50 vs $19.30 inside the US ($8 added for $500 insurance). So you guys in the lower-48 got nothing to bellyache about cost of shipping. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From gm4jjj at yahoo.co.uk Tue Sep 1 06:25:59 2015 From: gm4jjj at yahoo.co.uk (David Anderson) Date: Tue, 1 Sep 2015 11:25:59 +0100 Subject: [Elecraft] [KX3] CW +SSB with external transverter problem Message-ID: Scenario: KX3 with external transverter and amplifier on 144MHz. (Transverter RX/TCswitched from KX3 keyline out). Wish to use CW+SSB feature where hitting the key in SSB mode transmits CW. This is an option in the CW WGHT menu, selected by tapping 1. CW in SSB is something that is used on VHF DX where fading sometimes means having to quickly switch to CW from SSB during a QSO. Result: Tapping the key in SSB mode now keys the PTT line to transverter at the keying rate, irrespective of DLY setting or whether VOX or PTT is selected. So it cannot be be used as the relay switching in the transverter and amplifier is not capable of switching at the CW keying rate. Questions: Is this how this feature was meant to work? Could it be altered so that the CW VOX delay is honoured when using CW in SSB mode? This would then allow the feature to be useful with external PTT (Keyline) driven transverters.

I've published some SSB bandwidth measurements using pink noise as excitation. Because pink noise contains all frequencies, the spectra resembles music and speech, and is dynamic, it excites IMD in a manner comparable to speech. http://k9yc.com/P3_Spectrum_Measurements.pdf http://k9yc.com/FTDX5000_Report.pdf So far, I've measured only a few rigs using pink noise, but of those I've measured, I've seen very little difference between them. On the air is a very different story -- it's VERY common to see distortion on SSB signals in the form of both upper and lower sidebands on audio peaks. Because it is present in both sidebands, I strongly suspect it's caused by power amps that are over-driven, or poorly tuned, or improperly biased. We hear it as splatter (sometimes as wide as 10-20 kHz), and see it on the P3 and horizontal lines corresponding to audio peaks. 73, Jim K9YC ______________________________________________________________ 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 jermo at carolinaheli.com From ae4pb at carolinaheli.com Tue Sep 1 07:26:37 2015 From: ae4pb at carolinaheli.com (ae4pb at carolinaheli.com) Date: Tue, 1 Sep 2015 07:26:37 -0400 Subject: [Elecraft] K3S trouble doing PSK31 w DM780 In-Reply-To: References: Message-ID: <00eb01d0e4a9$120f8f80$362eae80$@carolinaheli.com> Check your HRD configuration in the sound card settings: HRD/DM780/Options/Soundcard - verify the output transmit device shows the K3S sound card.

Do you have anything connected to the Line In jack? The USB audio in is disabled if there is a plug in the Line In jack. Adjust the slider on the computer soundcard control to about 2/3 of full and then adjust the K3S Line In (Mic gain used in DATA mode) to produce 4 bars solid with the 5th bar flickering on the ALC meter - you can do that in TX TEST mode so no RF is transmitted. 73, Don W3FPR On 8/31/2015 11:44 PM, Steve Muenich wrote: > Hi all, > > It's my first time posting to this group as I recently got my K3S #10121 on the air.

I think I have it working reliably now with my external keyer in SSB +CW now. It is still a bit funky even with the internal keyer chosen after a start up with VOX AUTO OFF enabled, you have to switch to CW put VOX ON then back to SSB mode to get CW in SSB to work with VOX. It might have been better if the VOX was off for the paddles not to key the PTT at all in SSB + CW as it is rather disconcerting and not good for relays in the transverter for it to have the keyline keyed at the CW speed. 73 David Anderson GM4JJJ > On 1 Sep 2015, at 16:16, David Anderson wrote: > > Hi Jim, thanks for replying. > > I am running the latest firmware and I do have VOX delay set in CW mode.

Hi Bob, I've got one of these, in addition to a vintage HP 8590D. Specs are similar, the HP is a bit better, but not a lot. Both are blown away by some of the best of SDRs, including the K3 with P3/SVGA. While the P3/SVGA can display only 80 dB, the front end is good for about 100 dB, the display can be scaled up to view down to that level. Not as good as the Rigol or HP, but P3/SVGA frequency resolution can go down to 1 Hz (2048 point FFT for a 2 kHz span), two orders of magnitude better than the Rigol or HP. Rigol phase noise is specified as -80dBc/Hz at 10 kHz; the original K3 (with original synth board) was measured by ARRL as -140dBc/Hz. Bottom line -- the Rigol and HP are fine for looking at harmonics and spurs, but useless for looking at occupied bandwidth. Take a look at the plots in this link, especially slide #8, K3 steady carrier at 25W. I can't do this with my Rigol or my HP! http://k9yc.com/P3_Spectrum_Measurements.pdf 73, Jim K9YC From gm3sek at ifwtech.co.uk Tue Sep 1 13:44:19 2015 From: gm3sek at ifwtech.co.uk (Ian White) Date: Tue, 1 Sep 2015 18:44:19 +0100 Subject: [Elecraft] K3S IMD Questions In-Reply-To: References: Message-ID: <007d01d0e4dd$d9b900f0$8d2b02d0$@co.uk> I found very much the same as Rick did, with a completely different test setup (SDR-IQ). The details vary somewhat with frequency and supply voltage but the three main features reported by Rick remain the same: >the ten watt PA has worse IMD just before the big PA kicks in, in the >11-12 watt range. >Then it is very clean (approximately -40 db for third >order) at its best, and ok in the 30 watt range (where it would be set to run >my 8877 amp) > but then gets quite ugly above 65 watts. And I mean in the -20 db range at 100 watts. My figures confirm those three main features (assuming we're both reporting 3rd order IMD, "dB below either tone"). The other important feature is that the levels of higher-order IMD do not fall quickly when tuning away from the main signal. If we had reported "total occupied bandwidth at -60dBc", those results would not look pretty at all! Those measurements were first made about 7 years ago on my original low-serial K3, and today I made similar measurements on the new K3S. The 10/12W PA is different from the one in the K3 (two TO220 RF power transistors in the K3S, where the K3 had three). However, the 100W PA is the original module from my 7-year-old K3, so the IMD performance of that module may not be representative of current production. Today, anyone can make 2-tone IMD measurements using a modern SDR and a little care in setting up the input levels. The K3 itself provides the 2-tone test signal (CONFIG:2TONE On). If anyone can report comparable results for an all-new K3S/100, that would be very interesting to see... but don't expect any radical changes in those three main features reported by Rick. 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of >Rick Stealey >Sent: 01 September 2015 16:18 >To: elecraft at mailman.qth.net >Subject: Re: [Elecraft] K3S IMD Questions > >I have been playing with a Flex 6300 here in my shack recently.

Let's not forget that the response of any measurement is the combined response of both the measurement system and the device under test (DUT). An important test of any spectrum measurement system is its frequency resolution, which can be tested by its response to a steady unmodulated, unkeyed carrier. Like slide #8 in http://k9yc.com/P3_Spectrum_Measurements.pdf Likewise, we must qualify the dynamic range of the measurement system -- when does it begin to contribute distortion due to its own non-linearity. This is what K2XT ran into in his tests.

Yes, the K3 and K3S are a bit cleaner with higher power supply voltage. K6XX showed this in a presentation to NCCC a few years ago. It's on my website. All of my testing has been done with power supply in the range of 12.3 - 12.6V. 73, Jim K9YC From mtkoszew at gmail.com Tue Sep 1 14:27:47 2015 From: mtkoszew at gmail.com (Marty) Date: Tue, 1 Sep 2015 14:27:47 -0400 Subject: [Elecraft] P3 - SVGA Monitor Compatibility Suggestions In-Reply-To: References: Message-ID: <4E609E9D-2B9E-45A9-8271-C5AD8778E7AC@gmail.com> Thank you for your responses.

You probably also know that the phase noise of the analyzer should be, as a rule of thumb, 10 dB better than the device you're measuring. The 6300 claims -140dBc at 10 KHz offset for its reference oscillator. I believe that's more or less the same number Elecraft claims for the K3 synthesizer.

But with MMTTY I have my Windows slider at 20% and the Mic/Line Level control is still so sensitive that a change from 6 to 7 takes the ALC from 3 to 5 bars. These low setting then require an increase in VOX gain that then makes it too sensitive on SSB. Lowering the Windows gain exacerbates the problem. VOX and Mic gains should be totally independent. Sadly, in the K3 (both vintages) they are not. If I had the appropriate serial cable I would go back to serial control and Line In/Line Out.

Message-ID: My apologies if this is a FAQ. I've been looking all through the archives and can't seem to find an answer, so I'm turning to the good folks of the Elecraft reflector for some guidance. I'm considering my first home HF station radio upgrade since 2000, and I'm looking at the K3S. The number of options are overwhelming at first, so I've been reading and trying to narrow down what I'd need to get started. I chase DX and do some contesting (all modes), so I'm thinking I'll get some tighter filters, I know I'd like to be able to run an RX antenna for low band work, possibly look at the sub-RX option as well for listening to the other side of a split operation, etc. Here's my main question: If I'm building from kit, are there any particular options I'd want to make sure I install first as to not make things more difficult later? For example, if I add filters now, then add the sub-RX later, am I making things more difficult than if I added the sub-RX first? Would I be putting myself in the position of having to tear the roof off the house to just upgrade the kitchen? (Sorry, best analogy I got at the moment.)

In-Reply-To: References: Message-ID: <55E62F05.3080806@embarqmail.com> Chuck, There is no one good answer, your ideal K3S configuration depends on your operating goals and aspirations as much as anything else. My advice (remember it is free and may be worth all of what it costs:-) ) is for you to order the basic K3S/100 (perhaps with the KAT3 if you do not have resonant antennas) and use it for a while to determine the more frequent bandwidths that you use. The DSP does provide very narrow bandwidth filters, but they cannot help if a strong station near your operating frequency triggers the hardware AGC (S-9+40 dB). Once you have determined your filter width needs, then purchase filters that come close to those bandwidths and add them. Operate some more, and when you think you are ready, add the KRX3 (with filters the same as you selected for the main RX). I am assuming that you are looking for the lowest K3S entry price that you can find, and the above is it. If price is not the object, order what will be suitable for your goal of working DX - the SubRX is indispensable in the long run, but if you have not been using dual receive in your operations yet, it can wait - you still have 2 VFOs and can work split easily without the SubRX. Extra filters are good for CW operation where your receiver will be bombarded with strong stations on nearby frequencies - they can result in the hardware AGC kicking in and desense your receiver - preventing that is the purpose of the added roofing filters. The K3S comes with the KXV3B as standard, so that will allow you to use an RX antenna (as well as transverters and IF output). The thing I am advocating is that you need to consider your desired filter set first. The situation is that the filters in the main RX are physically covered by the SubRX, so if you already have the subRX installed, it must be removed to add/change the filters in the mainRX. It is not really that difficult if you have built from a kit, but is just an extra step. Adding filters to the SubRX entails removing the cover and the board from the SubRX enclosure metalwork - you need access to both the top and bottom of the board to install and secure the filters. So IMHO, your choices for incrementally building your K3S to what you ultimately want centers around the filters that you want to install. If you want to 'do it all at once', and your operating style is mainly CW oriented, I would suggest installing the 400 Hz filter in both the main and the sub, although you may want to use the 250 Hz filter either in addition or instead. If you are more SSB contest and DX oriented, choose either the 2.1 or 1.8 kHz roofing filters (but not both). You will find the KRX3 useful for contesting/DXing, but whether you add it initially or later is your decision. In other words, the best K3S configuration for you is based on your operating desires, goals and preferences. As confusing as it is, the fact remains that Elecraft has provided a transceiver that can be customized for your individual needs, and that is what makes it complicated. 73, Don W3FPR On 9/1/2015 5:02 PM, Chuck Milam, N9KY wrote: > My apologies if this is a FAQ.

I re-ran the same tests today and reconfirmed that, across a 60dB range of input levels to the SDR-IQ, the measured IMD3 levels change by less than 1dBc. Making further tests at 100W PEP, I measured IMD3 levels close to -30dBc at 1.9MHz and -27-28dBc at 14.2MHz... but then deteriorating with frequency towards -20dBc at 28.5MHz. However, I do confirm Jim's measurements that the IMD3 values at the 50W level are at least 15-20dB better. When driving a PA at 30-50W, the K3 or K3S will almost never be the limiting factor in determining IMD. Responding to Don's point: all of these IMD measurements were made at an indicated supply voltage of 14.5V. Following discussions in this forum some years ago, the supply voltage had been deliberately increased to help improve the TX IMD performance. I must repeat the warning that these measurements were made with a 7-year-old KPA100 module in a new K3S so they may not be representative of recent examples of either the K3 or an all-new K3S... but in other respects the trends are clear. 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of >Jim Brown >Sent: 01 September 2015 19:28 >To: elecraft at mailman.qth.net >Subject: Re: [Elecraft] K3S IMD Questions > >On Tue,9/1/2015 10:44 AM, Ian White wrote: >> Today, anyone can make 2-tone IMD measurements using a modern SDR >and a >> little care in setting up the input levels.

Studying this measurement, I have several thoughts. First, the resolution bandwidth appears to be about 30-40 Hz at -70 dBc, compared to 60 Hz for the K3 with P3SVGA. That's very good. Also, those peaks that show up in the range of 260-310 Hz either side of the carrier are visible in the waterfall and are moving in the waterfall, so I suspect they are some sort of modulation. Note that they are not visible earlier in the waterfall. > Do you know, when you say you see X dbc what effective bandwidth that > is? i.e. how to translate that into signal power in a 1 hz bandwidth > like ARRL does? No, I don't know, because we don't know the effective bandwidth of our measurement systems. > Because with the FFT spectrum analyzers there is no fixed bandwidth > filter sweeping across the spectrum. Right. We've been working with both swept measurement systems like TDS (Time Delay Spectrometry) and dual channel FFT since 1980. I had a TDS system in 1982. Cost me $12K. > ex: at 1 khz offset (14051= 5 divisions) phase noise is ~-95 dbc. but > what would that be in a 1 hz bw? No good answer, for the reason noted above. But this measurement shows that this test setup is very good for measurement occupied bandwidth as long as you stay out of non-linearity (that is, either too close to the top or bottom of the A/D). By all means save this measurement and compare it with what you see with the new synth board. 73, Jim K9YC > > Rick K2XT > > > > From fptownsend at earthlink.net Wed Sep 2 14:11:09 2015 From: fptownsend at earthlink.net (Fred Townsend) Date: Wed, 2 Sep 2015 11:11:09 -0700 Subject: [Elecraft] Probably a long shot here but I need a MH2 part In-Reply-To: <5FA6F3DB-766F-450A-9BCA-167CBA8DA5A3@gmail.com> References: <5FA6F3DB-766F-450A-9BCA-167CBA8DA5A3@gmail.com> Message-ID: <004f01d0e5aa$cee21b30$6ca65190$@earthlink.net> Hi Frank: Just a guess, I really don't know, but Bob Heil has always been quite supportive of parts requests.

It will have a list of other associated upgrade kits. If you think some of the upgrades have already been installed, download the instructions for each and do a physical examination of the K2 to see if any of those have been previously installed. In addition to those upgrades, look at the designations on the IF crystals. If they do not end in "-S", those crystals should be updated as well for better filter performance. If the KSB2 is installed, look at those crystals as well. If you need to update the KSB2 crystals as well as the main RF board IF crystals, order the matched set of 14 crystals - if only the RF board needs updated, order the set of 7 crystals. If you are replacing the crystals on the KSB2 board, consider widening the OP1 filter width to 2.4kHz instead of the original 2.1kHz. Of course, you should update the firmware. In addition, the AF Gain control is likely to be scratchy, so order a new AF Gain pot and install the Alternate AF Gain Control Wiring mod. I would advocate doing all the upgrades at once while you have it open. The cost of each of the mod kits is quite reasonable ($10 to $20 range), but the firmware is priced at $54 and is the most expensive part of the upgrade. If there is no KSB2 board, then the 2nd Xtal Flattening Mod can be skipped, but I would install all the others, including the crystal change. 73, Don W3FPR On 9/2/2015 5:28 PM, Mike Herr wrote: > I am looking to upgrade a friend's older K2, sn 280.

Yeah, I hope so too. I then hope that Elecraft will say "Screw all this touch screen nonsense". I mean, unless they plan to write an eyes-free interface for it. Which I'm sure Icom has not. It's sure gonna suck if something breaks that pretty touch screen sometime. How about having tactile controls and voice output so that drivers who put these things in their mobile stations can watch where they're aiming their cars instead of looking at their radios?

For me, keeping my fingers as near to the keyboard as possible is one of those little things that contributes to the score. Think about how much effort is wasted messing with a mouse and then getting your fingers back to proper keys. Give me a few simple knobs and a keyboard and I'm happy and efficient. I'm happy that Elecraft has put the horsepower in the radio and not gone overboard with the flashy light stuff. Is the tide turning?

The nice thing about the ic7300 is that it uses direct RF sampling, which is probably the way to go in the future. I'm not sure if the touchscreen will add real value for operating. I'll have to try. As I wrote before, I expect that the K4 will be a direct RF sampling device, high performance, just as easy and flexible to use as a loaded K3/P3, and all the features. 73 Arie PA3A From glen.torr at gmail.com Thu Sep 3 06:52:13 2015 From: glen.torr at gmail.com (Glen Torr) Date: Thu, 3 Sep 2015 20:52:13 +1000 Subject: [Elecraft] Icom IC-7300 In-Reply-To: <55E7EF99.8010701@xs4all.nl> References: <55E78B78.6090403@aol.com> <55E7EF99.8010701@xs4all.nl> Message-ID: Hi Wayne, Thank you for the thoughtful comments on the IC7300.

Simple and efficient interface was part of my decision. 2. Although the rig lacks band switches, it has function buttons that support limited macro's to set band/mode/other which fits 99.99% needs for anyone who will RTFM and utilize it. 3. While integrating the P3 would be nice it adds $700 to an already premium feature /cost rig. I'm purchasing incrementally so I'd find it unacceptable to have a large blank space on my radio if /until I decided to purchase the P3. 4. My background is Electronics/Computers and I currently work as a Systems Analyst ($4 dollar way of saying really high level support engineer). "Modern" isn't always better in my view. There are MANY more modern looking rigs that don't perform at the level of the K3S in my opinion. I'd rather put $4 into performance, support, and upgradability, than $2 into pretty/modern looking. The point being the more complex the system the more likely to fail and higher expense. Here's a crazy idea if you want modern with touch screen. Get a tablet(windows) with rig control software. That will give you the bleeding edge technology with full touch screen control. Personally I'm surrounded and use fancy tech all day long. When it's time to get on the air I want simple, straight up, and reliable. Not intentionally bashing anyone. Just my $0.02.

When I use a BW of 1.8 KHz or higher in SSB mode, everything looks good on a waterfall display. But when I reduce the BW to 1.7 KHz or lower, a chunk approximately 250 Hz wide and centered at 1500 Hz is removed from the waterfall display. I originally thought it was related to the roofing filters as the effect happened at the same time that FL2 was selected, but after I set the roofing filters to "not installed" so that FL1 was used for all bandwidths, the problems still occurs. Any suggestions would be appreciated. KX3-K serial #1691 with latest production release firmware installed. The roofing filter option was ordered with the transceiver. 73, AL - VE3RRD From w7ox at socal.rr.com Thu Sep 3 10:59:00 2015 From: w7ox at socal.rr.com (Phil Wheeler) Date: Thu, 3 Sep 2015 07:59:00 -0700 Subject: [Elecraft] Comparisons K3S/KX3/K2 etc?

K3S is at 107dB, KX is at 104dB, and K2 appears twice, 80dB for the new model and 70dB for the older model. I presume if you apply the mod kits to an older model K2, it will bring the performance up near where the newer K2s sit. Rob mentioned in one of his presentations that for CW you need a better receiver that for SSB, and that ideally you want at least 80dB narrow-spaced dynamic range when working weak CW stations in crowded contest conditions with strong stations nearby. An up-to-date K2 meets this criteria, but the FT991 is quite a but further down the chart at 71dB. Don?t know where this Icom IC7300 will fit in, but I think, like the Flex radios, it is a direct-sampling SDR architecture, and it will be very interesting to see where it ends up. --? 73 de Matt VK2RQ Le 4 septembre 2015 ? 12:59:38 AM, Phil Wheeler (w7ox at socal.rr.com) a ?crit: All three are on this Rob Sherwood chart, Curt: http://www.sherweng.com/table.html 73, Phil W7OX On 9/3/15 6:19 AM, Curt wrote: > I hadn't been paying too much attention, guess > the K3 has been replaced by the K3S.

I bought the K-Line is because it was straightforward and not overly (and unnecessarily complex) and somethingthat I could work on if it breaks.

For typical, day-to-day operations, I would say anything over 200 watts is high power. Most contests recognize high power as anything over 150 watts. If you are a QRPer, anything over 5/10 watts (CW/SSB) is considered high power. Personally, if I have my KPA500 on and am using it, I consider myself running at high power, even if I'm only getting 300-350 watts out. 73 de, --Ian Ian Kahn, KM4IK Roswell, GA EM74ua km4ik.ian at gmail.com 10-10 #74624, North Georgia Chapter #2038 PODXS 070 #1962 K3# 281, P3 #688, KAT500 #860, KPA500 #1468 -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of David Ahrendts Sent: Thursday, September 3, 2015 12:35 PM To: Elecraft List Subject: [Elecraft] OT - High Power?

As for the IC7300, most of the time you will likely be using the most commonly used functions which appear to be tied the physical knobs and buttons, and not have to touch the screen that much. SDR is the way of the future, heck it is the way now, and I think this is Icom's way of dipping their toe in the water and not upsetting their fan base by introducing an SDR in convention looking hardware. I am confident that they will be releasing a whole line of stand alone SDR rigs...

That puts them right there next to the knob to be 'touched.' While I don't have an experienced opinion on touch screens, I can see the sense of that setup. I have frequently thought of a series of three adjacent similar knobs for selections and settings. Selection / Setting / Value. Using knobs that function similar to Shift/LO / HI/Width / Speed/Mic and CMP/PWR on the K3 might save a knob, but could perhaps lead to more user error / miss-taps. I'm not going to attempt to figure out what might go with each knob. The selection knob might have a few banks in it. I'll leave the sorting out to those who design interfaces, if there is any interest.

I thought this would only occurred when the filter was installed but from your observation I'd say that's not so. I think what you're seeing is normal. There's an IF shift (or something similar) which moves the centre of the demodulated space up to 8KHz. This will also prevent the KX3 from switching to weaver mode and supress the hole in the centre of the demodulated audio but will confirm there's nothing un-natural going on. Weaver mode is essential to provide the minimal roofing filter width in direct conversion SDR architecture. In SSB mode the hole is of no consequence and not audible. In digital modes it can be supressed by keeping the IF bandwidth high. The 8KHz IF mode is really there to supress low frequency punch through from things like local AM broadcast station interference. 73's Peter VK4JD -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Al Duncan Sent: Friday, 4 September 2015 12:56 AM To: elecraft at mailman.qth.net Subject: [Elecraft] KX3 PBT problem I have RX xFIL set to "normal" in the menu so that the PBT control adjusts bandwidth.

Absolutely! The FT-991 will be much more noisy, suffer much more QRM from adjacent signals and suffer much more blocking from strong signals on the other end of the band.

I was the first buyer from Ham Radio Outlet. I just sold it. Having spent the last part of my career as a Usability Engineer - I was not impressed with the FT-991. Not from a performance stand point and most importantly not from a usability stand point. However, I think that larger, color, touch-sensitive displays are the future of pretty much all U/I's. I personally expect that Elecraft plans on the K3S to remain as a main line product for many years to come. However, I think we're at the cusp of a tidal change. It's the way of technology. Faster, more powerful, more specialized processors will probably make super-hetrodyne obsolete. It certainly has been an enduring technology and one that is still remarkably capable. I might add that I truly appreciate the K3 and the K-Line. I sold my first set a few years ago and went with a high-end Icom. After about 6 months I sold it and bought another K-Line. I will not make that mistake again! All the arguments supporting the current K3 front panel arrangement are all valid and I completely support them. I like having the kind of control the K3 gives me. On the other hand, I'm working on a complete flat-panel, touch sensitive interface using both Windows 10 and Linux (Probably OS/X as well) because I designed U/I's for a living and I'm curious to see what can be done. I can easily envision a knobless, buttonless, completely integrated flat-panel transceiver whose entire user interface can be reconfigured at will be the user. Truly - it's only a matter of who will do it first. I would probably buy one. But - it would not replace the K3. 73, Doug -- K0DXV On 9/3/2015 8:48 AM, Henry Pollock - K4TMC wrote: > Sherwood Engineering test data is available at > http://www.sherweng.com/table.html. > > The FT-991 was added back on 8/05.

The question will be what quality ADC Icom uses in the front end of the 7300 and how clean (phase noise) they can make the synthesizer (clock). If they have enough ADC bits to provide dynamic range, their claimed synthesizer phase noise comparison should put the 7300 at about the same level as the Ten-Tec Eagle in the Sherwood "chart" (e.g., 92-95 dB IMDDR3, -134 dBc @ 10 KHz phase noise, 125-130 dB 100 KHz blocking [ADC limited]). If Icom "cheaps out" and uses an ADC with limited resolution (number of bits) like some of its commercial products, the 7300 is likely to fall way down the list - into the neighborhood of the IC-7000 or FT-2000. 73, ...

On mobile installations, they are very distracting, therefore very dangerous. If there isn't a labeled button for it, it isn't easy to use.? Also, long presses to activate a function don't always work well when you are on a bumpy road, which describes a lot of our major highway and city streets these days, especially in southern Arizona. Meanwhile, one of the big problems even on base-station rigs is that you are still faced with MENU choices that can be several levels deep and completely non-intuitive.? How much time do you want to spend just getting the radio ready to listen in your preferred mode?? There can be literally hundreds of choices, some labeled in someones tech-speak.? (When was the last time you referred to mic input gain as multi/ch or digital mode input level as dAtA DT GaIN - menu item 65 of 178?)? Or worse yet, you select menu item 50, only to be told to press SUB to enable changing it. The KX3 isn't immune to this, either.? It sometimes requires that you press and hold KHZ for 3 seconds to enable changing a setting. I started operating FLDIGI in RIGCAT mode specifically so I could create macros that would : ? ? [1] change the mode, ? ? [2] set rig frequency, ? ? [3] set display freq, ? ? [4] change the bandwidth, ? ? [5] display a message to the user,? and ? ?

A major difference between these rigs and something like the IC-7300 or Flex 6xxx series is that our A-to-D converters (ADCs) are protected from wideband interference by a narrowband I.F. The K3/K3S uses crystal filters, while the KX3 uses precision, narrowband low-pass filters. In direct-sampling SDRs, the ADC is right at the front end of the radio, protected only by wideband LC filters. The result is typically 15-20 dB lower blocking dynamic range. More subtle is the effect of multiple signals, which can combine in phase to hit the limit of the ADC, resulting in unwanted images. It's a tradeoff; a direct-sampling SDR can allow you to look at multiple MHz of bandwidth on its spectrum display, if that's of interest.

I was intrigued by the SD-slot - probably has several uses. Subjectively I would prefer this one over the FT-991 mainly due to the screen and its general layout of controls.

When the band gets crowded, however, you'll start to deal with QRM. some of that QRM will be from people transmitting "dirty" signals, but if your receiver has distortion, some of the "QRM" you hear will be "generated" by the receiver itself as signals get mixed together. It is hard enough to hear that weak station with all the QRM on the band without having your receiver add "QRM" of its own. We care about the lab measurements because they help indicate whether the receiver is likely to be the weakest link or not.

On mobile installations, they are very distracting, therefore very dangerous. If there isn't a labeled button for it, it isn't easy to use. Also, long presses to activate a function don't always work well when you are on a bumpy road, which describes a lot of our major highway and city streets these days, especially in southern Arizona. Meanwhile, one of the big problems even on base-station rigs is that you are still faced with MENU choices that can be several levels deep and completely non-intuitive. How much time do you want to spend just getting the radio ready to listen in your preferred mode? There can be literally hundreds of choices, some labeled in someones tech-speak. (When was the last time you referred to mic input gain as multi/ch or digital mode input level as dAtA DT GaIN - menu item 65 of 178?) Or worse yet, you select menu item 50, only to be told to press SUB to enable changing it. The KX3 isn't immune to this, either. It sometimes requires that you press and hold KHZ for 3 seconds to enable changing a setting. I started operating FLDIGI in RIGCAT mode specifically so I could create macros that would : [1] change the mode, [2] set rig frequency, [3] set display freq, [4] change the bandwidth, [5] display a message to the user, and [6] start auto-tune and do all this with ONE click of a labeled button.

Funny thing is that I never think of the K3 as *functionally* an SDR radio, I guess because I don't have access to the I/Q signal -- unless it accessible in some sneaky way I don't know about. OTOH in principle it seems one could take the I/Q output of the KX3 and build their own "back end", playing all sorts of games -- not that I plan such an adventure. However, last Summer I did build one of the Tiny Python Panadapters in the April 2014 QST which was a fun project made possible by the KX3's I/Q port, though I soon replaced it by the much more capable PX3. Aside from its "cosmetic" features, which don't particularly appeal to me, the Icom-7300 looks like a radio not well suited for operation in crowded bands, DX pile-up situations, a strong-signal environment or Field Day. It will be interesting to see what the QST and Sherwood tests reveal. There are some SDR dongles which will provide a "look at multiple MHz of bandwidth" at very low cost :-) Such a capability can be useful in monitoring a band you're not currently operating. 73, Phil W7OX On 9/3/15 3:47 PM, Wayne Burdick wrote: > Hi Phil, > > Just to clarify: Both the KX3 and K3/K3S are SDRs. A major difference between these rigs and something like the IC-7300 or Flex 6xxx series is that our A-to-D converters (ADCs) are protected from wideband interference by a narrowband I.F.

Of course, it hinges on a number of factors -- including those you brought up below -- and I could be surprised. Even so, while I'm not spring-loaded against SDR rigs (the KX3 is basically an SDR radio, after all, and I enjoy mine), I can do without a touch-screen interface.

The nice thing about knobs is that over time you develop "muscle memory" where each one is and how to adjust it. You can make the adjustments without thinking about it, so you can keep your mind focused on operating.

You can make the adjustments without thinking about it, so you can keep your mind focused on operating. A touch screen might be handy for some things, but the prime operating controls should be knobs IM (not so) HO. :=) Alan N1AL ______________________________________________________________ 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 vk1zzgary at gmail.com From wunder at wunderwood.org Fri Sep 4 00:39:27 2015 From: wunder at wunderwood.org (Walter Underwood) Date: Thu, 3 Sep 2015 21:39:27 -0700 Subject: [Elecraft] Icom IC-7300 In-Reply-To: <55E9099F.6010303@embarqmail.com> References: <6877B97C-6E82-4624-B0C8-EFFB5F2997DE@comcast.net> <55E9099F.6010303@embarqmail.com> Message-ID: <07BB7756-CC51-4DE5-9206-E081DDCD955E@wunderwood.org> I apologize in advance if this is getting far off topic, but there is a blog that reviews audio equipment purely on the basis of ?knob feel?.

But, being an OT, I like my knobs and switches. Surprisingly, I haven't bought a TS-991. At the Huntsville Hamfest, I ordered a Flex 6700, as well as a K3S. As a concession to the knob-twiddler in my personality, I pre-ordered the Maestro console for the 6700. Aside from having some actual knobs, I can operate it anywhere in the house, on the patio, etc. as long as it can reach my wireless signal. 73 de Jim - AD6CW On 9/3/2015 7:33 PM, Brian Denley wrote: > I'm with Chris.

The K3S is unbeatable. That being said, my forays into the world of direct sampling DDC/DUC radios suggest that their receivers may have an edge in simply sounding "better" - subjectively cleaner/less fatiguing with slightly more readability on very weak signals, compared to my K3 and Orion. The direct sampling radios have a long way to go to become all-around great radios, but my impression is that 5-10 years down the road, they will dominate (in a knobbed form).

I would appreciate some advice on how to proceed with diagnosis and correction. First the basic background information: KX3 #8094. Firmware versions: MCU = 2.33, MCU = 1.33. I'm running the KX3 configuration utility Ver. 1.14.4.11 on Linux Mint 17.2 [uname -a => 3.16.0-38-generic #52~14.04.1-Ubuntu SMP Fri May 8 09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux ]. To calibrate I did the following: I attached a suitable 100W dummy load to the KX3. Then I ran the KX3 configuration utility. I executed the TX Calibration Gain. It runs fine with no errors until it reaches 52 MHz. The relevant lines with the failure message on the computer screen are: Calibrating 52.000 MHz TxGainStartTune Invalid response to "TQ;" Calibration failed I then decided to try the TX calibration instructions in the KX3 manual. As with the KX3 utility all went well except for the 4.0 W at 52 MHz test. When I got to 4.0 W on 52 MHz it appeared that the output was stable. That is the 4.0 W was holding steady. When I pressed the button to turn off the tuning the message in VFO A displayed was "d=017." The message in VFO B was "ERR TXG." I repeated the test at 4.0 W. The message in VFO B stayed the same. The message in VFO A changed to "d=042." A third attempt produced "d=046" message in VFO A. VFO B had the same "ERR TXG" message. I then ran the test at 6.0 W. There was no error. The error does not suggest what to do next. Any advice would be appreciated.

This one isn't really rare but does have some things going for it. It has the tan base rather than black or chrome. These were available but very few were ordered on the "Original" version of the bugs. Also, the serial number puts it in the first production run after Vibroplex moved from their Broadway St, NYC address to Portland, Maine. The Portland factory started serial numbering their production with much lower numbers sometime after this one was made. It still has the Broadway St. NYC label on it but Vibroplex's historical records indicate it was actually made in the Portland factory. It's in good (not super) shape, showing normal wear and tear from use and the label has been re-glued. It will come with an original Vibroplex carrying case that is all original except the leather carrying handle has been replaced (by me). The old handle had gotten torn and was lost. Carrying cases in this condition are getting hard to find. Asking $150 shipped anywhere in the US for the package and high resolution pictures will be emailed on request.

And I don't think we have to worry about that. However, before Elecraft goes the touchscreen route I would much rather see them use a colour LCD screen on their transceivers than the type they use on the K3/K3S/KX3. They are OK, but so much more could be displayed (or at least less cryptically) when you aren't constrained by a predetermined display. Firmware upgrades could give you new display options, like reducing the size of one display item (or temporarily removing it) to give you more room to look at something else!

Technology is "stampeding ahead" and all ham gear makers are susceptible to the changing landscape. I hated win8.0/8.1 because it was geared to touch screen tablets (which I do not have). I'm now waiting for my free upgrade to win10 and return to more reasonable UI. I have no smart phone or any cell phone. My wife has a MOT "flip phone" that does phone calls...enough for us. She lives on her I-pad3 but already got her win10 upgrade on her laptop which had win7. My phone is a ten-year old Panasonic wireless 5-GHz phone that does speaker-phone for my OTE hearing aids. I'll get blue-tooth on my next pair. I chose the K3 partly because it has "knobs", which are more comfortable for making adjustments than using the mouse. Yeah I'm an old f--t ham, 5-years retired, and heading toward 60-years on ham radio (2018). K3/10 and KX3 with 2M satisfy my needs (until I can afford a KXPA100); saving for my new Synth's for the K3. 73, Ed - KL7UW From: Jim Rogers To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Icom IC-7300 Message-ID: <55E98265.8000302 at gmail.com> Content-Type: text/plain; charset=windows-1252; format=flowed Can we be done with the IC-7300 stuff?

But touchscreens have been around for a long time and a lot is known about them. The all time great defining application for them is in restaurants for wait staff to enter your food selection. Repetitive operations using touchscreens require physical use research which includes designing a mounting scheme that does not produce physical strain under normal operation. Normal accuracy of touch point taps has to be accommodated in screen apps. Large tap points that appear and vanish with an appropriate logic produce the great workplace improvements. E.g. the wait staff screens. The stuff behind successful touchscreen apps is mind boggling, often involving years even now decades of incremental research and program changes. This touchscreen editor I'm using right now on my smartphone is one such. Any one of the list of must-do's ignored and the app is likely doomed. Touchscreen radio? Not wishing anyone bad luck but they've bitten off quite a piece of work. Radio ops are very repetitive in contests. You'll never sell me a pure touch radio for contesting. Maybe a talky with the form factor of my iPhone 6+ with a Bluetooth linked manual control and separate Bluetooth linked amp/transmitter. The obvious (to me anyway) touch interface is to use a smart phone app that can also run on a tablet. Most people have already bought it and will replace it when it breaks for dozens of unrelated needs. Don't have to embed that cost and development into the radio. Let me use my house wifi or Bluetooth to link to my K3. The K3 change is to provide the interface. An internal board that listens to wifi and Bluetooth. All single chip stuff these days. Will be interesting to see what survives of touchscreen radio when the latest and greatest crowd has lost interest and moved on. 73, Guy K2AV On Friday, September 4, 2015, Bill Stravinsky via Elecraft < elecraft at mailman.qth.net > wrote: > Not sure why I needed to know about an Icom 7300 and am guessing it has a > touchscreen.

Hi, The KX3 is usually set up by default to run at 9600 baud. There is a menu option in the radio (RS232) to set it at 38400 which is what I usually tell people to do. The Elecraft utility auto senses baud rate, so it doesn't matter but Win4K3 doesn't so you need to have it set up in the KX3 itself. Let me know if this fixes the issue please.

You're a ham, pull out your soldering iron, and the manuals for the K3 and the headset to see what pins are used for mic and earphones and make your own. XLR4 connectors are widely available and easy to wire. So are 1/8-in plugs if you buy good brands like Switchcraft and Neutrik. My favorite vendor is Full Compass. Part numbers for the 1/8-in plugs are near the end of http://k9yc.com/GroundingAndAudio.pdf > From what I hear most headsets that heil manufactures has a 1/8" mini plug at the end of the cable.

If installing a DVK in the K3/K3S disabled the front panel microphone jack there would have been much howling and gnashing of teeth on this list for years. > Of course if I connect the microphone to the rear jack it bypasses > the DSP board. Not true. Both mic sources are processed by the same DSP circuits. The rear mic jack audio is routed from the KIO3 (P76/J76) to the AF DSP (P50/J50). The front mic is routed from the mic jack to the AF DSP via P32/J32. On the DSP board, audio from each microphone passes through its own buffer/preamp and the desired mic elected in U4. If the front mic does not work after installing the DVK, and resetting the mic selection (and bias) does not fix the issue, the most likely cause is improper (re)installation of the DSP board - either bent or misaligned pins on P50/J50. 73, ...

I installed a KDVR module yesterday in which my K3 recognizes that. But I cannot get any power output or ALC when I connect my microphone to the front microphone connector. According to the service people at Elecraft they tell me that the microphone connector in the front is connected to the DSP board. And you must not have one of the pin connector seated correctly. Well, I have taken the K3 apart 4 times and put it back to together again making sure that everything is seated the way it should be and it still will not work. So I connected my microphone to the rear connector and lo and behold it gives me output power and ALC. Of course you need to use the PTT to get it to work. That is the only drawback to that theory. But, I thought I would try PSK/Rtty this morning. So I started FLDigi and connects to my K3 via Digi Keyer II, but I don't see any receive audio on the waterfall display. And I also tried MMTTY and got the same exact thing for Rtty. I did switch the mode to AFSK. Would this issue that I am having also effect the receive audio for PSK31 and also Rtty? I did write an email to K3Support this morning, but I doubt I will hear anything until Tuesday. Any suggestions/help would be very much appreciated.

Receive audio is on a different connector than the front panel mic audio. However, if the DSP board (or front panel) was not installed correctly (misaligned/bent/broken pins on one or more connectors) it could impact Line Out audio. Connect a set of powered speakers to the Line Out jack and see if you have audio there. 73, ...

Unlike the CM-500, it is readily available in Europe (see Amazon). For a more lightweight on-ear style of headset, I can still recommend the Koss CS-100. As Jim so often says, the K3, K3S and KX3 don't need a "gold-plated" microphone or headset. They perform superbly with almost any computer-style headset. Make your own choices about comfort and ruggedness, but those transceivers can make them all sound equally good. The "best in class" transmit audio quality of the K3, K3S and KX3 has been almost overlooked amid all the other publicity about receiver performance and phase noise. In more than 50 years, the K3 was the first transceiver that had *ever* brought me unsolicited compliments about audio quality. With their different voices, my wife and guest operators still receive the same kinds of comments, and it's all done with those cheap headsets. 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of >Ken >Sent: 05 September 2015 13:20 >To: elecraft at mailman.qth.net >Subject: Re: [Elecraft] K3 Microphone Connection > >I'm with Jim, I have a Koss SB/45 that plugs directly into the rear of >the K3.

However, on your second point, "toss them in the garbage" is a no-no from an environmental standpoint. ANY electronics disposal should be via proper recycling. There are multiple local dropoff points for e-waste here in rural "flyover country" so I'm sure anyone in a more populated/more environmentally conscious area should have no problem finding a recycling center. /rant off HI HI!! That being said, perhaps someone could establish a clearinghouse for unneeded/unwanted boards leftover from upgrades such as your SYN boards. If Murphy has anything to do with it, a few days or a week after you decide to dispose of the boards someone will be looking for one or both of them.... 73, Al On Sat September 5 2015 1:27:32 pm Barry wrote: > Installed the 2 KSYN3A boards yesterday.

The 10 dB rule-of-thumb is a *minimum* and it would be better if the measuring instrument were more than 10 dB better. I'm not sure that the Flex radio originally mentioned meets that phase noise requirement. If its phase noise is on par with the K3's then it's not suitable for an accurate phase noise measurement. Depending on the numbers, you *might* be able to say "A is better than B," but you couldn't say how much better with any certainty.

Works great with a Logitech K360 wireless keyboard (a real steal at $19). I made a few QSOs in both CW and RTTY mode (FSK-D on the KX3) to check things out. The PX3 won't work with just any USB keyboard. For example, those that include other built-in USB devices such as trackpads will not work with this implementation. So I strongly recommend not purchasing one until we provide a list of those we've tested. There are a still a few wrinkles to work out, but it is most definitely a nice addition to the PX3.

Since you report that switching from ANT1 to ANT2 and back corrects the symptoms, I would suggest that you check the tightness of your antenna coax to make certain all connectors in your antenna system are tight. A loose connector or bad coax link can often behave like you describe. 73, Don W3FPR On 9/5/2015 7:37 PM, KE1B wrote: > I put my new K3S under ?contest conditions? for the first time this weekend, and discovered an intermittent problem. > > Running SSB (it may happen in other modes as well, I don?t know), the radio will stop outputting power.

It is indeed a very challenging user interface to design. I'm sure that there will be dozens of solutions that work on iOS and Android. Building Bluetooth into a radio and allowing full control through it would be the gateway that needs opening. I favor a touch enabled flat panel connected directly into the radio's microprocessor. Everything I've done so far shows that the latency through the serial port is a usability inhibitor. It's never going to feel natural until it is updating visual objects within a few milliseconds. What I'm envisioning is something like 20 to 30 objects that are completely customizable for size, color, function and location. The user could develop a particular layout and save it. Each band and mode can be a different layout. And then there is the interactive voice interface with commands like "go to fourteen zero seven zero mode PSK", "send CQ", "answer K0DXV" or "load contest configuration three". Might be handy to be able to just tell you radio what to do and watch the interface change to accommodate you. I expect that 10 years from now I'll walk into the kitchen in the morning and say "Mr. Coffee - Make a large regular coffee". My coffee maker will say "Right away" and the beans will start grinding. I'll then take my coffee into the shack and say "K5 on" and a marvelous radio will come to life... 73, Doug -- K0DXV The real key is going to be the degree of customization available.

I am experimenting with "FA;" which will retrieve the VFO A frequency. After I send the command, I get back responses three bytes at a time which I accumulate in a ring buffer until the response is complete. Sometimes I get the correct frequency in the response, sometimes only an "FA". Manual frequency change from the K3's front panel does not seem to be acknowledged. FA followed by the frequency does effect a frequency change. Is there a use group dedicated to UART K3 control?

I mostly work SSB with my K3?but am working on code speed. I use WIN4K3 as a control program and panadaptor. ? These differences are purely subjective and without measurement. All computer controls unchanged and K3 controls returned to previous settings. ? Before?going to the new synth I had a no signal noise floor S meter reading of 4 or 5, occasionally 6 The panadaptor background had scattered 'clutter' noise and I could see very?close adjacent signals but not read them. The noise floor 'line' on the display was at about -102 db and 4 to 6 db wide peak to peak ? After the mod I had a no signal noise floor S-meter reading of 2 to 3 sometimes 4 The panadaptor background was much clearer, signals more distinct and close together signals were easier to?separate and copy? The noise floor line was at -106 to -108 and the line was thinner by a couple db. ?

The K3/0-Mini was delivered with an Owner's Manual. The manual is limited to describing how to set up the Mini to work with a PC, how to operate with the RemoteRig 1258 MKII System (which we are not using), and how to update the Mini's firmware. The Owner's Manual does not contain any information about how to use all of the controls on the Mini, or any information about its Menu and Config selections. Since the person who will be using the Mini is not familiar with at all with the Mini, or its big brother, a K3, we will need a user-oriented manual that provides the all the information that an operator will need to know. I can download copy of a K3 manual, however, I don't know if the explanations described for a K3 also pertain to the functions of the K3/0_Mini. Please let me know if there is a more complete user-oriented Operator's Manual for the MIni, or will the K3 manual correctly explain all the functions of the Mini? Thanks, George.

Keep in mind that the front panel of the K3/IO-mini (including all knobs, menus, etc.) directly controls the corresponding settings of the ?remote? (or ?target?) K3 that it is connected to. When you change a setting on the K3/IO-Mini, it is actually changing the settings on the target K3. If you go into the configuration menus, you?re changing the configuration of the target K3. The only exception off hand that I can think of to this general statement is that K3 must be set for ?rear panel? microphone so that the mic feed that is coming from the ?remote? K3/IO-Mini to the target K3 which in fact is fed to the rear panel connection of the target K3, is utilized. Otherwise, if a front panel mic source is selected, the audio will not be fed into the target K3 from the K3/IO-Mini. The real question is whether the operator is familiar with using a K3 and knows how to configure settings to meet their needs. Thus, reviewing the K3 operating manual makes much sense since that is what is being controlled by the K3/IO-Mini. My comments are based upon using the K3/IO-Mini via remote rig directly to my remote rig controller at the target K3 (e.g. the 1258MK II system) and NOT using remotehams.com service. I am not familiar with remotehams.com setup, but presume that the same concepts apply.

Message-ID: Bill: I just finished installing the new boards in both my K3's. I did one radio complete and then did a quick test on 80m and 20m with both radios. I found the new boards quiets the receiver down somewhat and makes it easier to pull out the weaker signals. I have pretty quiet conditions at my QTH, all utilities are underground. My simple test was comparing Rig A (New KSYN3A boards installed) to Rig B (Old KSYN3 boards installed). I have not done any real tests to further evaluate the new boards, but in my case they have helped somewhat.... Maybe the new boards do really help, or perhaps it was me sub consciously wanting to believe that to justify the cost. 73 De Mike VE3YF http://www.ve3yf.com From p_hippenmeyer at bluewin.ch Sun Sep 6 04:12:58 2015 From: p_hippenmeyer at bluewin.ch (paul hippenmeyer) Date: Sun, 06 Sep 2015 10:12:58 +0200 Subject: [Elecraft] [K1] X-Lock & K6XX mounting?

Cool. I purchased my batch of stuff in stages too. Got the K3 in Nov of 2014 and then added the P3 (with SVGA interface for flat screen) along with second RX (SUB RX) couple of months later. It's all working great. Oh.....I added the AUX addition so that I could run diversity from a Beverage on the second receiver SUBR; and, I'm usually using the APF (audio peaking filter) with that. Use of the Beverage on 20-meters with the above has dropped my noise floor more than 12 dBM! The combo has really been helpful since I live just two blocks from a noise-generating shopping center. Don't think we can attach pictures here but I posted a picture of my current setup on my QRZ profile page. It shows a second flat screen for the computer side of things. Having fun drilling on the CWT weeklies sessions, using N3FJP's CWT logger. 73 and enjoy those new toys!

Vox operation still works to key the radio, but it is just an empty carrier. When I have the alc/comp meters up, I can see the audio levels rise and fall with my voice. TX power is set to 10W, not in split mode to a different mode. All the MH3 settings from the manual are correct.

If you have something plugged into either headphone jack (front or rear) it mutes the speaker by default. You can override this with a menu setting, and you can assign that function to one of the two soft buttons (I use SF2). Once you do that, SF2 toggles the speaker on and off.

Well after 3600+ QSOs with my KX3/SN190, I now have a couple of problems: 1- The DC plug is working intermittently.Think that I have to resolder it. Since I got the factory-built version, I would like to know what is the shortest way to (de)-assemble the rig to do the repair...? I Have the battery charger, tuner and roofing filters options in the radio. 2- The second pixel on the SWR display is lighted even without signal. Not a major problem .. just want to know what is going on ...

I'm just wondering if I could send the unit back and just cut my losses on it. I have it assembled except for the SSB? Module. For the past couple of months I have been trying to align the unit. Every single step of the process has been a battle. I have received help from the Elecraft Email subscription but I am just tired of fighting with it. I have gone over all of the solder point and made sure that they are good along with the components being inserted correctly, I also had electronic engineers go over it. I just can't get it to work. I can get it to generate a tone for the tone generator test but that is as far as I can get. I'm at the point that if I can't get Elecraft to look at it, then I'm just going to dump it in the trash and sign my thousand bucks that I have invested in it as a loss and try to save up for another radio. I don't know what else to do. I am really tired of fighting with it and it has become and object of frustration instead of a way to communicate with the world.

Use DATA A (or AFSK A for RTTY) instead of SSB to avoid that condition. 73, Don W3FPR On 9/3/2015 10:55 AM, Al Duncan wrote: > I have RX xFIL set to "normal" in the menu so that the PBT control adjusts > bandwidth.

In-Reply-To: References: Message-ID: <55ECDE95.1050907@embarqmail.com> Doug, I don't know about X-Lock, but I can comment on the K6XX CW Tuning Indicator. Just cut the leads to the prescribed length (do not dress them any shorter), and then just let the board lay on the RF board in the right front corner. It will do no harm there, and if you ever have to move it out of the way for service on that area of the RF board, it is easy to move it. Make all the connections with stranded wire because solid wire will break after some number of moves. 73, Don W3FPR On 9/5/2015 4:22 AM, Douglas Hagerman wrote: > Has anyone come up with a good mounting technique for the X-Lock and the K6XX tuning indicator in the K1? > > From ns9i2016 at Bayland.net Sun Sep 6 21:03:00 2015 From: ns9i2016 at Bayland.net (DGB) Date: Sun, 6 Sep 2015 20:03:00 -0500 Subject: [Elecraft] K3 ERR 12 V In-Reply-To: <55EC4C13.4000409@roadrunner.com> References: <248879FE3CD4490E84077A095E23FA01@D816K82J> <55EC2E05.5080404@subich.com> <55EC4C13.4000409@roadrunner.com> Message-ID: <55ECE244.1000800@Bayland.net> Just finished up the jumper trick.

I got a new jack from Elecraft and fixed mine, and then glued it to the board with a small bead of epoxy around the perimeter of the jack - too much and you can make a non-conductive mess if any gets inside the jack itself. I recall I did remove the board just as a precaution so I would do no harm to anything else - see the assembly manual and work backwards. I can't comment on the second pixel of the display, but that would logically seem to be a bad (always on) output from a display driver - that being said, I would contact support at elecraft.com and see what they have to say. If you have to send the KX3 in to fix the display problem, you may as well let the techs there at Watsonville fix the power jack at the same time. 73, Don W3FPR On 9/6/2015 7:51 PM, Pierre wrote: > Hi Folks.... > > Well after 3600+ QSOs with my KX3/SN190, I now have a couple of problems: > > 1- The DC plug is working intermittently.Think that I have to resolder it.

If you really want to trash it, I'll pay the postage, send it to me. :-) There are a number of builders on this list, there's a compendium of them on the Elecraft web site [or was], and they range from building a kit from opening the boxes to finishing kits half-built. I really recommend you investigate that, I love my K2 [4398], and it has gotten a lot of field use and on summits. It's a great little radio you can hold in one hand with amazing operating characteristics.

Not a major problem .. just want to know what is going on ..." I will take a shot at that question, Pierre. If the "faulty" pixel is in the S-meter, it means that you have the rf gain turned down. Tap the AF/RF-SQL knob once so you can adjust the RF gain, and rotate the knob clockwise until the display says RF -0. It is mentioned in the manual under "Receive Settings", "AF Gain, RF Gain, and Squelch". I had the same question about two years ago. I hope that was the problem.

However, if you decide on the K2, I would go for the DSP over the KAF. It is more versatile, but does have a different sound.

The basic K2 is CW only for 80 thru 10 meters (but not 60 meters). If you add all the options to give it the full 160 thru 10 meter band capability (6 meters must use an external transverter), SSB, Noise Blanker, and audio DSP filtering, you will have a total price that approaches the K3/K3S, but you still have to build it. If you ask one of the builders for hire to build it for you, the price can even exceed that of the K3 (depending on your chosen options). It will not do AM or FM, and will not receive very far outside the ham bands. The K3/K3S can be used for general coverage receive with the addition of the KBPF3, so if general coverage is part of your desires, the K3/K3S is your only choice. 73, Don W3FPR On 9/7/2015 9:07 AM, Dauer, Edward wrote: > > Yep, I thought about that - as soon as the K3S came out. > > But the K2 costs less; it offers more kit building, which I enjoy; and it > would be easier to answer for when the XYL asks ?Why do you need TWO of > those?"

When I "finished" my K2 I was almost sad to see the project go. But it was 4 years or so of fun, from mid-1999 thru 2003 or so, as the new options (SSB, KPA100, etc.) came available. And since then some upgrades, here and there -- even some 3rd party add-ins. The K2, as it has turned out, is the last major ham radio kit.

Last week I received my K3S/100 (S/N 10270) kit, including KDVR3 recorder, KRX3A second receiver, and .5ppm TCXO. After getting the kit assembled per the assembly manual, I got to the checkout phase prior to installing the 100W amp, and second receiver. The unit powered on as it should, however I got no "ERR PLL" message on the display as it stated I probably would. When I got to the Synthesizer Check, I was able to get into "TECH MD" mode, and turned it "ON". However, I was not able to get to "SYN1" to display in the VFO B area. The bottom part of the display would start with what I assume was supposed to be the time (however it was in the area of 37:20:20??), then as I rotated the VFO B knob, it would step through what I assume was the date, then "0.00", "13.6V", "1.05A", "FP 28C", "PLL1 2.9" (ranging up to "PLL1 3.2"), "PLL2*0.0", "AFV 0", and finally "0.0 dBV". This is all I can get. Of course, with this being a holiday, contacting Elecraft wouldn't work, so I thought I would throw this out here to see if anyone had any ideas as to what might be wrong with my unit. Thanks, and I hope everyone is having a great Labor Day (where applicable). 73, Ken, KJ9B From aldenmcduffie at sunflower.com Mon Sep 7 16:56:42 2015 From: aldenmcduffie at sunflower.com (Phil Anderson) Date: Mon, 07 Sep 2015 15:56:42 -0500 Subject: [Elecraft] K3S - Ordered Today!!

That is why you will see very little of a kit where you solder SMD parts. Fine activity for those few who can do it well, but considering that kind of skill as "common" is not just unrealistic, but more like silly. Beyond skills, there is the problem of how SMD parts are made and distributed. Particularly on a tape reel containing 1000's of the same part with precision spacing on the tape, meant to feed a machine. Bazillions of SMD parts are made, distributed and fabricated on boards with these methods where the first handle-able output is a fully populated and soldered PC board. That's just a reality these days, and discrete part kits are now an odd, tiny, tiny, niche in the universe of all electronic that goes on. If you really want a discrete parts kit experience of some substance, best buy yourself a K2 kit, before Elecraft decides to drop it. 73, Guy K2AV On Mon, Sep 7, 2015 at 4:16 PM, Bill Frantz wrote: > I have built several non-Elecraft kits which included some SMD parts.

Trying to keep MacLogger connected to the K3S via it?s KUSB for several days at a time (like Labor Day weekend).

I can't be certain of that, but I would get that cleaner residue off and try again. I would suggest that you remove the cleaner residue from the contacts with acetone - apply it with a brush or cotton swab and immediately wipe the area with a clean cloth of paper towel. Do only a few pins at a time, and do not let the acetone dry on the contacts or board. You may want to mate and unmate the front panel and RF board several times, cleaning between each to hopefully clean some of the 'goop' out of the female header. If you do not have gold pins on the connector to the front panel, consider asking Elecraft for the gold replacement pins. 73, Don W3FPR On 9/7/2015 5:27 PM, Nick Lelyak wrote: > Thanks Don, Guy > appreciate yours quick response. > I found out that problem disappears when front panel warms up to 37 C > and more. > Looks like problem somewhere in FP.

It effects epoxy, lacquers, paints, and plastics, particularly polystyrenes where its effects are almost instantaneous. Pour some in a polystyrene cup and watch it immediately cloud up. >From Wikipedia: Acetone is a good solvent for many plastics and some synthetic fibers. It is used for thinning polyester resin, cleaning tools used with it, and dissolving two-part epoxies and superglue before they harden. It is used as one of the volatile components of some paints and varnishes. Polyester resin, also called gel coat, in case you don't know, is the stuff PC boards are made of. Leave acetone in the paint department where it belongs.

If the board is flooded, the results can be catastrophic since residue flows under components and makes a mess. But carefully applied with a swab or small brush to a small area and mopped up with a paper towel it will do the job very well. The contact time *must* be short, and that is why one must work in small areas. Yes, alcohol can do a good job of cleaning flux too, but needs to have the same precautions - it can make just as much of a mess or more because alcohol attracts water vapor and causes it to condense on the surface being worked. Dip an opaque object in alcohol and remove it with a paper towel - note that the object will be wet with moisture. Besides, the job for the particular problem stated was not flux removal, but removal of some unknown compound from connector pins. Alcohol is likely to be ineffective. 73, Don W3FPR On 9/7/2015 7:02 PM, Fred Townsend wrote: > Don: > Acetone should NEVER be used in electronic assembles.

Last week I received my K3S/100 (S/N 10270) kit, including KDVR3 recorder, KRX3A second receiver, and .5ppm TCXO. After getting the kit assembled per the assembly manual, I got to the checkout phase prior to installing the 100W amp, and second receiver. The unit powered on as it should, however I got no "ERR PLL" message on the display as it stated I probably would. When I got to the Synthesizer Check, I was able to get into "TECH MD" mode, and turned it "ON". However, I was not able to get to "SYN1" to display in the VFO B area. The bottom part of the display would start with what I assume was supposed to be the time (however it was in the area of 37:20:20??), then as I rotated the VFO B knob, it would step through what I assume was the date, then "0.00", "13.6V", "1.05A", "FP 28C", "PLL1 2.9" (ranging up to "PLL1 3.2"), "PLL2*0.0", "AFV 0", and finally "0.0 dBV". This is all I can get. Of course, with this being a holiday, contacting Elecraft wouldn't work, so I thought I would throw this out here to see if anyone had any ideas as to what might be wrong with my unit. Thanks, and I hope everyone is having a great Labor Day (where applicable). 73, Ken, KJ9B ______________________________________________________________ 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 richarddw1945 at yahoo.com From wes at triconet.org Mon Sep 7 20:30:41 2015 From: wes at triconet.org (Wes (N7WS)) Date: Mon, 7 Sep 2015 17:30:41 -0700 Subject: [Elecraft] KSYN3A mod problem In-Reply-To: <55EE2638.4010905@embarqmail.com> References: <55EDECE7.7090209@embarqmail.com><55EE04E6.3040006@embarqmail.com><001201d0e9c1$60535ba0$20fa12e0$@earthlink .net> <55EE2638.4010905@embarqmail.com> Message-ID: <55EE2C31.3050708@triconet.org> Disband the terrorist EPA (A terrific idea regardless) and we could go back to Freon vapor degreasers.

Then, select the USB entry under Hardware. If you have a lot of devices, figuring out which it is could be a challenge, but it will most likely be one of the FTDI interfaces. My KUSB shows a current requirement of 90 mA. The Mac will try to put all devices on the USB to sleep when it goes to sleep, whether they are connected to a hub or not. When the Mac is awakened, it will try to reinitialize the ports as they were before the sleep condition, but if it is not doing this, then the software program should catch the wakeup notification and re-initialize the port. If it does not, you should file a bug report with the software package?s author to let them know they have something to fix. MacLogger DX is pretty good; it would surprise me if this isn?t already being done, but dropping an email to them is still a good idea. Note that the USB stack is being reworked for El Capitan, so until the final release, you may see major changes in the way things work. Things have become much better since the first developer release, but there are still tweaks occurring with each subsequent release as problems are uncovered.

Trying to keep MacLogger connected to the K3S via it?s KUSB for several days at a time (like Labor Day weekend).

Windows 8 was a disaster for Microsoft. Pretty much everyone involved with it left, retired or were fired. My last gig with the USAF was designing computer-based training for various systems. I had to actually learn the systems in order to figure out how to train people to use them. As a usability engineer, looking at critical AF systems... well I wished I had that line - it would have been perfect! Windows 8 can be fixed though. Add an extra menu system for $5 and it works just like 7. Windows 10 is better. But not better enough. Microsoft failed to get the complete message. Apple is wise. They have a separate OS for each platform. Windows 10 - like 8, does desktop and tablet equally badly. Various linux-based U/I's remain the very best for the desktop computer. Linux Mint Cinnamon is my favorite. Good touch screen systems move components around so what you need is there when you need them depending on what you're doing. Flat, touch-enabled, color screens will be the defacto interface for a long, long time. Fortunately, most everything needed to make the K-Line happy runs just fine on Windows 10. FTDI drivers, for the most part, are bullet proof on 10. Sigh. Now that I'm done testing Windoze 10, I'll put the PCs back in the closet and plug in my Macs again. Life will be so much easier... 73, Doug -- K0DXV On 9/7/2015 5:36 PM, Fred Jensen wrote: > The P5 would likely be Romeo ... > > Seriously, touchscreens vary greatly, and a great deal seems to depend > on the underlying software controlling and sensing it.

Probably about 18-22 hours per kit without testing. I'm 71 and still able to work on this stuff but did buy a new magnifier lamp this summer (I wore out the previous one). Secrets to doing smd work have been previously discussed so I will not bore anyone by repeating. If Elecraft started offering smd kits I would have lots more work building kits for others! But doing a kit for a K3 would be probably beyond my patience (and failure rate). I think they have a lot of very small smd parts on the board which get much more difficult (I like 0603 and larger).

There are three types of alcohol commonly available. Methanol often used as shellac thinner, ethanol, booze if you wish, which EverClear is, and isopropyl which is often found in rubbing alcohol sold in drugstores. They vary in toxicity and can react differently with some materials. You chemists out there can enlightens further.

I have a calibrated VSWR tester that indicates my antenna and feedline VSWR is 1.05:1. When I connect the P3TXMON and transmit, the PS display shows my VSWR is 2.0:1 into my feedline and antenna. I also tried testing into a dummy load. The VSWR tester shows a VSWR into the dummy load of 1.01:1, whereas the P3TXMON shows a VSWR of 1.29:1. Power level readings on the P3TXMON are within 5% of measured power levels using a power meter, so the P3TXMON is reasonably accurate measuring the transmitted power. In reviewing the P3 manual, I do not see any methodology for calibrating the VSWR measurement accuracy for the P3TXMON. Any suggestions on how to calibrate the P3TXMON for better measurement accuracy?

I told her yesterday that I had just ordered the K2/100. She asked ?How much?? I confessed that with all the accessories and add-ons and the shipping, it was about $1,700. Then she asked, ?How long will it take you to build it?" I told her that the reviews I read said about 30-40 hours, so for me it would likely be about 80. She then reflected on the fact that our 8-year old grandson builds twenty dollar Leggo kits in about two hours; thirty dollar kits in about three; and so on more or less linearly. So, she said, ?It costs about $10 an hour to amuse him. For you it?s about $21." Impeccable logic.

Are you certain the one labeled "PC" is connected to the cable plugged into the PC (or USB to serial adapter)? If so, try another cable (or adapter). OK, if you have the K3S connected to the PC via the USB cable, then there is a slightly different situation (ignore the above). Look at the diagram on page 18 of the K3S manual. Note well that the connector on the end of the cable plugs into the connector marked PC and the connector with two cables emerging from it connects to the XCVR connector. Unplug and replug the RJ-45 connection and make certain it is seated all the way. If that still does not bring success and you have a USB to serial adapter (or a real serial port on the computer) connect that to the PC connector on the P3 as a test and see if you can run P3 Utility. 73, Don W3FPR On 9/8/2015 2:35 PM, Amateur Radio Operator N5GE wrote: > I have connected my P3 to my new K3S and it works very well.

I have no accurate means here this evening of measuring power, but the output from the KPA500 at an indicated 500W key down on the amp shows as only around 350W on the P3. I have the sensor between the KPA500 and KAT500, so the sensor is seeing a good VSWR. Just curious, as I know I need to make more accurate readings, but I'm wondering what others have found. I have adjusted the CAL up to 550 from its 500 default value, which seems to make things about right. I would never expect close agreement in power measurement as I know how hard that is to do, I spent a long time early in my (first! )career making and adjusting directional couplers for military applications, so I know the constraints! 73 Stephen G4SJP From KX3 at ColdRocksHotBrooms.com Tue Sep 8 15:17:54 2015 From: KX3 at ColdRocksHotBrooms.com (Lynn W.

If you are testing with the P3TXMON and your 'calibrated VSWR tester' in series with your feedline, then those numbers may be incorrect. The 'calibrated VSWR tester' is reading the SWR seen looking into your antenna, but the P3TXMON is looking at the SWR looking into the input of your VSWR tester - and that may be two different things. If you want to do a valid test, obtain the SWR reading on your VSWR tester, and then take the feedline off that tester and connect it to the P3TXMON directional coupler and compare the SWR reading obtained from that combination. In other words, while your VSWR tester may be calibrated at its output, there is no guarantee that its coupler does not introduce an SWR at its input. Switching the same coax from the output of your tester to the output of the P3TXMON is the only valid test. 73, Don W3FPR On 9/8/2015 1:49 PM, Robert Nobis wrote: > I am having a VSWR measurement accuracy issue with my P3TXMON.

As the sight faded, larger tape (or multiple lines) is great. 73, Rick wa6nhc Tiny iPhone 5 keypad, typos are inevitable > On Sep 8, 2015, at 11:38 AM, Don Wilhelm wrote: > > Ron, > > My P-Touch Label printer works fine for me. > You can get wire labels at an electrical supply house - letters A-Z or numbers - they wrap around the cable without sticking out, then make yourself a chart of which goes where. > > 73, > Don W3FPR > >> On 9/8/2015 2:27 PM, Ron W3ZV wrote: >> I am bound and determined to clean up the K-line rat's nest behind my radio desk.

You want the water to pick up the water because alcohol is a non-polar solvent meaning it does not pick up the ionic contamination. The water picks up the ions and alcohol picks up the water. Conclusion rubbing alcohol containing water works just fine although the 50/50 cheap stuff now sold is not as good as the 70/30 or 91/09. Best way to clean is to blot and or air squeegee the liquid off. Don't let it evaporate. That leaves the sold residues behind. When finished cleaning if you still have worries about water then bake out your board at 90 to 95 degrees C. 30 minutes is all that is needed. 73, Fred, AE6QL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of ae4pb at carolinaheli.com Sent: Tuesday, September 8, 2015 6:15 AM To: 'Ian White'; elecraft at mailman.qth.net Subject: Re: [Elecraft] KSYN3A mod problem When you purchase alcohol to use as cleanup it's best to get the highest concentration you can get, else, there is a risk of it leaving a residue and the evaporation rate is much slower.

This aims to ensure that chemicals such as flux cleaners and contact cleaners will not damage the plastics that are used in the majority of components. In return, component manufacturers try to avoid using plastics that would be damaged by solvents in common use. Undiluted acetone is not part of that agreement because it's simply too aggressive, as Fred describes. Although electronics-grade solvents are more expensive than bulk commodity solvents like acetone, for peace of mind they are worth the extra cost. 73 from Ian GM3SEK ______________________________________________________________ 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 jermo at carolinaheli.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 fptownsend at earthlink.net From n7rjn at nobis.net Tue Sep 8 20:58:59 2015 From: n7rjn at nobis.net (Robert Nobis) Date: Tue, 8 Sep 2015 17:58:59 -0700 Subject: [Elecraft] P3TXMON VSWR Measurement Accuracy In-Reply-To: <55EF5FE3.4050700@embarqmail.com> References: <55EBB7AB.1080901@sbcglobal.net> <55EF5FE3.4050700@embarqmail.com> Message-ID: Don, Thank you.

I am still thinking about SideKar. 1) cost - it may need to be a Christmas gift - it exceeds my max per item spending limit without approval. 2) Elecraft - what are they "going" to do with the keyboard on the PX3 and more important, SideKar is stuck with the DSP decode method from Elecraft, too. Fldigi has its own processing AND includes AFC. As pointed out by someone else, the Elecraft DSP does not have AFC to track psk31 (needed) or RTTY (not needed as much with wider signal). SO, SideKar is stuck with a good display/logging system but stuck with ok decoding. CW, why does the Elecraft DSP need a threshold level? For example MRP40 has AGC and AFC, why not Elecraft? This limits SideKar over fldigi and has made me think about my direction. For now, fldigi has better decoding. "you", SideKar, should push Elecraft to improve its DSP decode of CW/psk31/rtty... I don't expect "you" to have the DSP answers, either... Minus six for Elecraft (afc+agc*kx3+k3+ks3)=6... 3) Elecraft has never said anything about a logging function with the pX3 keyboard option, either. Plus one for SideKar. Christmas isn't that far off and SideKar is still an option even with the shaky decode issues. 73, steve WB3LGC On 08-Sep-15 6:42 PM, Shel Radin KF0UR wrote: > Steve, > > With the SideKar, you only have to enter the call once.

After installing theK3 Utility program, I plugged the USB cable in between my PC and the radio. The driver loaded OK, and made the radio COM 6.

Our customers like the decode/encode capability for its convenient, casual operation. Examples: - Field Day, when you get burned out on CW and SSB (I myself made a few dozen RTTY and PSK31 contacts in this year's FD, just using the paddle and message buffers -- no PC) - quickly pouncing on a new RTTY DX entity before long everyone else gets past thier Windows boot-up - showing non-hams what CW and other modes "look like" -- they can see both halves of a QSO since both RX and TX streams are shown We do have a long-term goal to continue improving the decoders, within resource limits. Any such improvement would come in the form of a free firmware upgrade. 73, Wayne N6KR On Sep 8, 2015, at 6:46 PM, Stephen Shearer wrote: > Thank you for the info. > > I am still thinking about SideKar?.

Some want it just to reduce clutter at their home station, while others take the rig camping, RV-ing, hotel-inc, etc., and want it for the reduction in stuff they need to bring and hook up each time. The USB port works with Windows, Linux and Apple platforms.

I also have a NUE-PSK modem. The big feature the HCT (and SideKar) bring to the plate is the logging capability, along with ADIF exporting. The connection to your rig (FT-817, KX3, etc) permits the SideKar to poll the rig for data like mode, band, (frequency), time.. so you log will have useful data. So, the SideKar is helpful in a contest situation, or for SOTA and similar activities. It?s also lightweight and can be self-powered. The NUE-PSK modem is a generic device, in that it can be used with almost any rig, and it will decode CW, PSK, RTTY, and may offer additional modes. It?s compact and can be updated to include a USB interface, which permits easy firmware updates and the ability to save all received the sent text. That?s not logging, but you can view the generated text file to look back on your activity. So each has it?s value (which is why I have both). And, both are quite QRP, unlike most laptop/computer based systems. 73 de Ray K2ULR > On Sep 9, 2015, at 12:19 AM, Phil Wheeler wrote: > > I use an NUE-PSK, which has it's own decoding (for PSK31 and CW), a keyer, etc. It's a bit of an oddball I reckon, but perhaps that's why I like it. > > 73, Phil W7OX > > On 9/8/15 8:39 PM, Shel Radin wrote: >> Steve, >> >> One important thing to me and the way I use the KX3 is that with the SideKar, you don't need a PC, laptop, tablet, etc. It's self contained. >> >> So for portable operation, it's lighter (5 oz) and smaller than bringing something else along.

I did just that with FLDigi on Raspian. Works great and gives me a low power, low cost Digital transcoder for more than just PSK31, RTTY, and CW. The only issue I wrote about in this chain previously is the need for a screen and a keyboard. I did that with a Bluetooth keyboard attached to an iPad which used VNC to the RPi2. Talk about using a sledgehammer to hang a picture hook. Of course, I had all these components already and wanted to reuse them. So, the cost was sunk for other purposes, not for a portable digital station. While this setup worked, it was a lot of stuff to carry. The epiphany that surfaced from the Elecraft reflector participants in this conversation was that a low cost, small laptop would provide all the logging, digital transcoding needs for a portable HF station predicated on the KX3. Often, you can find smaller laptops, refurbished, for less than $200. regards, Brian VE3IBW On Wed, Sep 9, 2015 at 10:00 AM, wrote: > AFAIK based on reading the SideKar site it's just reporting what the Kline > radio is giving it already decoded. $250 is a bit much when you think about > what the box does.

No. AUTO in the KX3 (or K3/K3S) means that the automatic antenna tuner is in-line rather than bypassed. To tune, tap ATU TUNE. The SWR is displayed, and it should decrease as the algorithm progresses. If the final SWR is higher than 2:1, you can tap ATU TUNE again within 5 seconds to initiate a broader search. This is useful with very narrow-banded antennas, or those that are electrically short or close to a multiple of a half-wave (very high-Z). The ATU stores up to 32 LC network settings per band. These settings are not recalled as you move the VFO in RX mode, as that could be distracting. But they are recalled when you transmit, or when you do ATU TUNE, change antennas, do A/B VFO swap, etc. You can clear all of the ATU LC memories on a given band by going in to the ATU menu entry and holding CLR (hold of the RIT/XIT offset control). In CW mode, the rig tries to avoid interfering with your sending when the ATU requires retuning for a new transmit frequency. The first time you transmit in a segment that requires an LC network change, the firmware will wait for the first significant pause (letter space), then update the ATU. This is indicated by the ATU icon flashing a couple of times. It's possible that your first transmission will be at a somewhat higher SWR because of this behavior, but it has the advantage of not chopping off the first element due to ATU relay delays. 73, Wayne N6KR From w3fpr at embarqmail.com Wed Sep 9 11:55:06 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Wed, 9 Sep 2015 11:55:06 -0400 Subject: [Elecraft] KX3 ATU Modes In-Reply-To: <55F0525E.5040806@msn.com> References: <55F0525E.5040806@msn.com> Message-ID: <55F0565A.4030903@embarqmail.com> Ron, It will not automatically tune without user action. Tap the ATU TUNE to initiate a tune. Once you have "trained" the antenna on each band segment, it will automatically recall those last used tuning solutions when you return to that band segment. The latter is the "automatic" action. See the KX3 manual page 14, lower half of the right column. 73, Don W3FPR On 9/9/2015 11:38 AM, w7hd at msn.com wrote: > My KX3 ATU is normally set to AUTO in the menu. > Does this mean it will automatically tune without user action? > If so, how do you set the SWR at which it begins the tuning process. > > I only have it in BYP when using the vertical antenna with the LDG > RT100 remote tuner. > From w7hd at msn.com Wed Sep 9 11:58:55 2015 From: w7hd at msn.com (w7hd at msn.com) Date: Wed, 09 Sep 2015 08:58:55 -0700 Subject: [Elecraft] KX3 ATU Modes In-Reply-To: <55F0525E.5040806@msn.com> References: <55F0525E.5040806@msn.com> Message-ID: <55F0573F.8090108@msn.com> Sorry, I misunderstood what AUTO meant.

Message-ID: <20150909.165202.10834.0@webmail03.dca.untd.com> I've found the Brother "touch system to be inadequate. The labels fade very quickly in sunlight and fade (albeit much more slowly) indoors. For cables both inside and outside, I prefer coloured tape. Scotch 33 is available in standard colours for this purpose and can be purchased at a real hardware store or "big box" retailer. To differentiate between cables, I make the first colour 1.5 times the width of the roll and subsequent colours standard width. For example: cable 45 vs cable 54. Cable 45 would have a wide yellow band and a regular width green band. Cable 54 would have a wide green band and a regular width yellow band. I do not use black or grey tape as they do not contrast well against black or grey cables. I do not use the same colour more than once so the colours can be distinguished. My experience is that violet tape does not stand up to outdoor use as well as the other colours. I use an arbitrary classification system so: Note that there are no same colours on the same cable so there are no lines 22,33,44,55,66,77,88,99. 1x series Lines to HF antennas 2x series Lines between equipment (rig to antenna tuner, for example) 3x series Control lines rotor, remote antenna switch, remote antenna tuner 4x series DC power 5x series AC power 6x series Grounds 7x series Lines to VHF-UHF antennas including repeaters 8x series not used yet 9x series not used yet Should you need additional lines for a specific classification, it is easy to add a 3rd digit with another normal width piece of tape. For example, another HF antenna line could be line 125: wide brown, normal red, normal green. Signal direction of travel can be indicated so: At the source, place the wide band right up to the connector, at the load, place the narrow band(s) right up next to the connector. I made up a table to indicate what goes where: (partial example below) CAPITALS indicate wide band. LINE COLOURS FROM TO NOTES 74 VIO - yel IC-7000 HF out 6m beam 8214 64' new 7-2013 75 VIO - grn IC-7000 VHF out 2m beam 8214 56' new 8-2012 I've found it important to date each iteration of the Line sheet to keep track of changes like adding another antenna. In each junction-remote tuner box, there is a waterproofed line sheet copy. I used a laser printer and then spray the sheets with Krylon matte clear until the paper is soaked and then let it hang-dry. I've had good results with this. Inkjet printing will run when it gets wet or even humid. For labeling outdoor objects, metal Dymo tape is hard to beat. The catch is that it is wildly expensive and takes vast amounts of money to purchase the specially constructed die-cast metal lettering tool. I spent half-vast sums of money for mine at a hamfest. The metallic tape comes (came?) in aluminum and stainless steel. UV proof and the adhesive is quite strong. For permanent writing, use a paint-based marker as the common "magic marker" ink is subject to quickly fading. Markal (company name) makes a line of high-quality paint markers as does Nissen. If you state permits it, the xylene-based paints work better than water-based. Check with WW Grainger or Fastenal. These paint markers mark on metal quite well but will flake off anything that flexes. The "Sharpie" metallic markers are suitable only for inside work. I've not had much experience with their "Sharpie" paint markers. 72, Tim Colbert K3HX ____________________________________________________________ Protect what matters Floods can happen anywhere.

I have never found any #33 in colors other than black. I generally buy cases of each color available in #35, plus cases of Super 88. Alan - N7MIT Alan R. Downing Phoenix, AZ From: k3hx at juno.com [via Elecraft] [mailto:ml-node+s365791n7607334h39 at n2.nabble.com] Sent: Wednesday, September 09, 2015 9:56 AM To: kd7gc Subject: Marking cables. I've found the Brother "touch system to be inadequate. The labels fade very quickly in sunlight and fade (albeit much more slowly) indoors. For cables both inside and outside, I prefer coloured tape. Scotch 33 is available in standard colours for this purpose and can be purchased at a real hardware store or "big box" retailer. To differentiate between cables, I make the first colour 1.5 times the width of the roll and subsequent colours standard width. For example: cable 45 vs cable 54. Cable 45 would have a wide yellow band and a regular width green band. Cable 54 would have a wide green band and a regular width yellow band. I do not use black or grey tape as they do not contrast well against black or grey cables. I do not use the same colour more than once so the colours can be distinguished. My experience is that violet tape does not stand up to outdoor use as well as the other colours. I use an arbitrary classification system so: Note that there are no same colours on the same cable so there are no lines 22,33,44,55,66,77,88,99. 1x series Lines to HF antennas 2x series Lines between equipment (rig to antenna tuner, for example) 3x series Control lines rotor, remote antenna switch, remote antenna tuner 4x series DC power 5x series AC power 6x series Grounds 7x series Lines to VHF-UHF antennas including repeaters 8x series not used yet 9x series not used yet Should you need additional lines for a specific classification, it is easy to add a 3rd digit with another normal width piece of tape. For example, another HF antenna line could be line 125: wide brown, normal red, normal green. Signal direction of travel can be indicated so: At the source, place the wide band right up to the connector, at the load, place the narrow band(s) right up next to the connector. I made up a table to indicate what goes where: (partial example below) CAPITALS indicate wide band. LINE COLOURS FROM TO NOTES 74 VIO - yel IC-7000 HF out 6m beam 8214 64' new 7-2013 75 VIO - grn IC-7000 VHF out 2m beam 8214 56' new 8-2012 I've found it important to date each iteration of the Line sheet to keep track of changes like adding another antenna. In each junction-remote tuner box, there is a waterproofed line sheet copy. I used a laser printer and then spray the sheets with Krylon matte clear until the paper is soaked and then let it hang-dry. I've had good results with this. Inkjet printing will run when it gets wet or even humid. For labeling outdoor objects, metal Dymo tape is hard to beat. The catch is that it is wildly expensive and takes vast amounts of money to purchase the specially constructed die-cast metal lettering tool. I spent half-vast sums of money for mine at a hamfest. The metallic tape comes (came?) in aluminum and stainless steel. UV proof and the adhesive is quite strong. For permanent writing, use a paint-based marker as the common "magic marker" ink is subject to quickly fading. Markal (company name) makes a line of high-quality paint markers as does Nissen. If you state permits it, the xylene-based paints work better than water-based. Check with WW Grainger or Fastenal. These paint markers mark on metal quite well but will flake off anything that flexes. The "Sharpie" metallic markers are suitable only for inside work. I've not had much experience with their "Sharpie" paint markers. 72, Tim Colbert K3HX ____________________________________________________________ Protect what matters Floods can happen anywhere.

I am not one bit sorry I did that! I started out with a K3/100 kit, internal ATU and two additional filters: the 400 Hz 8 pole and the 1.8 KHz 8 pole filter. I loved it in this rather ?bare? configuration, but?.. After moving to a new QTH and freeing up additional funds, I added the sub receiver, two meter module, FM filter, and KX144RFLK. Having the second receiver is great, as it allows me a lot of flexibility with antenna selection and diversity receive. I use an 88 foot long doublet for transmit on 60 - 6 meters; a Hustler 5BTV ground mounted as my diversity receive antenna. Because it is connected to the ANT2 port, I can also transmit into the vertical as well as receive, should I want to. I?ve also added the P3, KAT500, and KPA500 to the lineup. I highly recommend the P3. It is unbelievably useful. Sell that Icom - you won?t be sorry. 73, Jim / W6JHB Folsom, CA > On Wednesday, Sep 9, 2015, at Wednesday, 11:10 AM, wb0m at flashdog.us wrote: > > Hello Everyone, > > I am considering selling my Icom IC-756 ProIII, with Inrad roofing filter, to help pay for a future K3S.

The anomaly decreases the Mic Gain to zero. I manually reset it to 8-9 which restores SSB power output to normal. I haven?t tried any other actions to restore the Mic gain. All indications I have this is a Mic Gain problem. > Since the mic gain, displayed in a digit format, is reported as literally going to the digit zero, we must remember that everything inside a dotted line within the K3 is entirely SDR. We must carefully avoid our decades-ground-in tendency to think of troubles in our familiar and comfortable analog fashion. I do include myself in this habit and sometimes catch myself going retrograde, having to do a brainwave CTL-ALT-DEL, and start over from the beginning. This trouble is presenting inside the K3's SDR dotted line. Of the eight "pots" on six shaft centers on the left side K3 front panel, all those rotational functions *advise* the CPU of their state via multiplexed one and zero state data lines. There is no gain potentiometer inserted anywhere in the various audio paths, nor is there a steady state control voltage from a potentiometer controlling a linear pass transistor in the audio string anywhere, thank your lucky stars. Remember "scratchy" audio? Just another of the analog bugaboos happily banned forever by the K3's mostly SDR hybrid scheme. The MIC control function uses a *shared* encoder assigned three separate unrelated settings. If the encoder or its physical data connection to the CPU was a problem, it would affect all three functions MIC, SPEED and DELAY on the front panel. I have heard of the encoder going bad and needing to be replaced. If the encoder is miscellaneously sending a string of "decrease" encoder signals, it should also happen in SPEED or DELAY mode. All the encoder can do is send increase or decrease signals. You would have your CW and VOX delays going to nothing, or your CW speed going to the 8 WPM minimum. The CPU knows what function is currently "on the knob" and the static values in force for the three lower left encoder functions. Exactly one function at a time is currently assigned to the knob, and the CPU interprets a "decrease signal" accordingly. The decrease signal travels to the CPU over a multiplexed data line which is either there and properly working for many diverse functions or is not for all those functions. Doesn't this really start to smell like a program issue? That gets you to the next thing -- if it is a firmware bug, then the trouble is present for ALL K3 users running the affected firmware version(s). And we should have lots of reports because every single user of the firmware could be experiencing the same problem intermittently. The only program code that could isolate the trouble to a *few* users would have to be external to the K3. Is it possible for an external program to set the MIC gain? This of course is impossible in an analog radio priced for ham customers, so analog thinking would not suggest that. The trouble would have to be IN an analog radio. But since the K3 is digital, we note that page 1 of the K3 programmer's guide has "MG * Mic gain" cell in the command table cheet sheet. That just might be an "Aha" moment. If an external program intermittently sent an MG 000 command to the K3, you would inconveniently find the MIC gain set to zero, intermittently. Not a K3 intermittent physical problem, but a K3 *commanded* to set MIC gain at zero, a command which the K3 mindlessly obeys, as yet unable to read a contrary indication from the mind of the operator. Let me know when the mind-reading K7 shows up. I want one. Get rid of a lot of cables and input devices. I, myself, with my terribly soft and mumbly radio voice, with extensive trials managed to get a good setting for K3 SSB MIC gain, compression and TX EQ settings. I was directed to those settings, and had those settings confirmed as clear, punchy and understandable over the air, by the PVRC contest guru crowd. Predictably I haven't myself touched those settings in maybe three or four YEARS now. They are still where I put them. They better stay there, too. People don't hear me nearly as well when I'm non-K3-processed. It's like turning off the amplifier. Repeating myself, if it's a third party program on someone's particularly configured PC, or with a particular parallel combination of running third party programs, then the mic gain to zero problem would be scattered and rare. If it's in K3 firmware, it probably would have been caught in alpha or beta testing. If if got to the general field in a production release, Big E would have been buried in complaints. Myself, I would suspect something incoming on the control serial line like "MIC 010" losing ASCII digits and arriving as "MIC 0", or mangled to "MIC 000" or something like that. Does the K3 process a "MIC 0" command or consider that an invalid command? I don't know. But poor physical connections for external serial lines, or overloading USB hubs have resulted in mangled command strings, or two programs fighting for exclusive use of the serial line, and those kinds of problems far beyond Elecraft's control, are as common as nails. And by my reading of this reflector those troubles are frequently first blamed on the K3, even if the true chances of that actually being correct are worse than hitting the lottery. Do follow the support advice to disconnect all the external programs and see what happens. The complete list of all possible combinations of third party programs that can drive a K3 over a serial connection is an absolute witches brew of widely scattered quality, from the sublime to the simply awful, sometimes implemented in a hamshack with grotesque physical arrangements. There are programs in distribution that have known problems that the coder has no intention of ever fixing, for any number of reasons, and some have publicly stated such. What you got is all you are ever going to get with these. Meaning that your particular problem could have been reported to the author a thousand times without effect. That in a programming world that swiftly keeps moving on. And of course this is without mentioning the ubiquitous fallibility in PC Bios programs and operating systems. Elecraft is your friend.

I just recently went from the PROIII to the K3S. Although, my PROIII did NOT have the Inrad roofing filters. ? The gotta haves for me were 100 watts, antenna tuner, 250hz 500hz 2.1khz?2.7Khz and 6Khz roofing filters, and P3 Panadapter. I am a contester and DX chaser.? I actually ordered with 200hz 5 pole filter, but that went unavailable during the time my unit went into production. The combination of the 500hz and 250hz filters serve my purpose well. I chose not to go with the second RX at this time as I never used the dual watch on the proIII, and got very used to using the spectrum scope and switching either back and forth between split or RIT. I just never felt comfortable listening to TX/RX freqs simultaineously. Just like I struggle trying to carry on a verbal conversation and coping CW, one or the other please! Just my preference, and I'm comfortable with it :) My main focus is contesting and was looking to improve RX capability on CW and RTTY/digital. Also wanted to get rid of all the sound card interconnects for AFSK operation. Secondary was improving SSB blocking even a little bit over the PROIII. The K3S has proven to be all and more of what I was looking for. CW and AFSK RTTY are 10 times better to work in contests. So, so much more pleasant on the brain and ears! SSB turned out even better of an improvement than I guessed there would have been. Lots more flexibility in RX tweaking with NR/AGC/RX EQ and roofing filters band width for all modes than was capable with PROIII. It used to be if I could hear them I could work them. Now I'm finding, I can hear more than I can work, quickly! I have found another layer or two that was always there but couldn't hear. It all comes down to what you "gotta have" for your operating style. For me the gotta haves were better RX filtering/flexibility, P3 to see the band, 100 watts and antenna tuner, and able to get all the sound card cables and interface stuff out of the way. ? BTW, PROIII's are still holding value pretty well. I don't think their value will change much between now and spring. Although, if you have another rig to keep you on the air till then, you could sell now just to make sure. I purchased my PROIII used in 2009 and could have sold it for a bit more than I paid, but ended up selling it to my son for a little less. They are holding value, "I think"?due to the price tag of newer rigs hitting the market, keeping the price tag somewhat inflated for the older rigs with attractive functionality, IMHO. ? You will not regret a K3 or K3S. ? 73 and good luck! ? Gene, N9TF ?

I don't use any of the mic gain command strings in N1MM+. Is it possible that you have a macro associated with one of the memory buttons('s programmable function), which sets the MIC gain, and one of your lesser-used N1MM Logger messages is virtually pushing that button (SWT/SWH)? 73, ~iain / N6ML From mcduffie at ag0n.net Wed Sep 9 20:45:35 2015 From: mcduffie at ag0n.net (mcduffie at ag0n.net) Date: Wed, 09 Sep 2015 18:45:35 -0600 Subject: [Elecraft] [KPA500] Reduced band sensitivity when in OPER In-Reply-To: References: Message-ID: On Wed, 9 Sep 2015 17:18:33 -0700, Chris Johnson wrote: > I just noticed that if I flip my KPA500 into OPER, the band sensitivity drops by a huge amount.

Sounds like a probable bad PIN diode. You should see minimal change. I show one db change in audio level on WSJT on six meters. Check with E-craft on troubleshooting the diodes and see what they say.

All the N1MM macros are the "standard" button pushes for the DVK messages. A raspberry Pi may be in the future for my station control now that an inexpensive touchscreen is available. But I will stick with N1MM+-K3 interface for now. In my shack I use LP-Bridge to provide virtual serial ports, including one to the K3. However, this anomaly has appeared when using my old Vista laptop with both N1MM Legacy and Plus. A passive logger could possibly indicate the anomaly's source. Any suggests for a software logger? Consider that some other command could also be mangled into MG 0. The mangling can occur anywhere in the command. What would be useful here is a passive logger for the RS-232 connection. It would simply monitor the connection and log everything sent over it. It sounds like a Raspberry Pi application to me, but I like to play software that is near the hardware level. You could also do it with an Arduino, which gets rid of the OS, but also makes display output harder. YMMV. 73 Bill AE6JV Guy, I don't believe I've indicated this is an analog problem. It's most obviously a software/firmware problem. There is no "MG" command in the N1MM DVK macros: CATA1ASC SWT21; CATA1ASC SWT31; CATA1ASC SWT35; CATA1ASC SWT39; The only commonality between occurrences is N1MM (various versions) and a pair of K3's with various firmware versions. There are no common cables, USB hubs, serial cards, computers, etc. That is not to say that some errant event occurs on rare occasions. It is interesting to not nothing else goes astray on the K3 when using N1MM. Since the anomaly occurred with a K3, and another K3 owner had a similar issue this year, I posted here first. Next I'll give it a try on the N1MM+ e-mail group. I'm watching an episode of Sherlock Holmes on PBS as I type this message-what an appropriate coincidence, or is it? 73, Bill, K8TE Since the mic gain, displayed in a digit format, is reported as literally going to the digit zero, we must remember that everything inside a dotted line within the K3 is entirely SDR. We must carefully avoid our decades-ground-in tendency to think of troubles in our familiar and comfortable analog fashion.

The combination of the 500hz and 250hz filters serve my purpose well. I chose not to go with the second RX at this time as I never used the dual watch on the proIII, and got very used to using the spectrum scope and switching either back and forth between split or RIT.

Also wanted to get rid of all the sound card interconnects for AFSK operation. Secondary was improving SSB blocking even a little bit over the PROIII. The K3S has proven to be all and more of what I was looking for. CW and AFSK RTTY are 10 times better to work in contests. So, so much more pleasant on the brain and ears! SSB turned out even better of an improvement than I guessed there would have been. Lots more flexibility in RX tweaking with NR/AGC/RX EQ and roofing filters band width for all modes than was capable with PROIII. It used to be if I could hear them I could work them.

I?m the owner of a 7? year old K3 fitted with a sub-receiver, DVR, TCXO option, 100W PA, Auto-tuner and probably too many IF filters (as I have belatedly discovered). ? I added the two new KSYN3A boards back in the spring which has produced an excellent improvement to both receivers?.then a few weeks after that Elecraft announces the K3S?.grrrrrr ? My K3 has been updated with all the hardware mods. Its appearance is like new. So far it has given me flawless service though not at all stressed (no contesting, field days, SOTA, motocross mobile, lending to friends, pawn shops, etc.) ? Here?s my dilemma. Do I keep it and retrofit what I can as new K3S options become available? Do I sell it outright (along with a lot of other stuff to raise the $$) and buy a completely new, comparable K3S or do I buy a new bare-bones K3S-10 and transplant the options I can from my older K3 to a new K3S? ? There?s a big $$ consideration in this decision. But first, I am interested in opinions on any K3S performance improvements. ? For those of you who have gone from a K3 to a K3S, I would be interested in your observations and opinions of the following: 1. Does the new K3S DSP board significantly improve the audio coming out external speakers? 2. Aside from new attenuator steps, what improvements do you notice improvement with the revised main RF board? I?m really curious about this as it?s the biggest piece of the K3 that cannot be updated. 3. Aside from a new ATU bypass relay, is there any different performance with the KAT3A auto-tuner? 4. Aside from new PA devices, any noticeable changes/improvements to the 100w PA? 5. Is the only thing revised in the KRX3A sub-receiver the addition of the new KSYN3A board? The KIO3B, KXV3B and KBPF3A upgrades are of lesser importance to me in this decision process because of my operating style. ? BTW, I liked the old K3 bezel appearance better than the K3S especially after I had my K3 bezel custom engraved by WB2ART (just razzing you Wayne). ? I?d be interested in hearing about your experiences and/or opinions on the above. ? To keep the mail volume low, perhaps replying to me off list would be best. n1lq at arrl.net I?ll let you decide on how to proceed. ?

I don't run NaP3 currently on the shack PC on which I run LP-Bridge. There, I usually have Chrome open as well. The anomaly occurred once during this week's Phone Fray during which I also had an instance of IE open. On that computer, CPU cycles are not an issue. This PC runs on Windows XP, soon to be replaced with a "modern" Dell and Windows 8.1. For communications with the K3, I run N1MM+ through LP-Bridge via an on-board dual Serial port board. I don't run LP-Bridge on my mobile/portable laptop. I tried it once, but it doesn't have sufficient horsepower. With that computer I use a USB to dual serial port adapter for K3 communications. I have observed the anomaly on both computers although it rarely occurs on either. I'll put together a more concise description for the N1MM+ reflector later today. Both computers have anti-virus and firewall programs running simultaneously. In their current configurations, neither has issues with CPU cycles during contesting. I use Startup Delayer to manage what and when programs come up on boot to help manage CPU use. That comes in handy during the rare occurrence when a re-boot is necessary during a contest (always be prepared). I also run the VE7CC CC cluster client when the contest allows and I choose to enter in the assisted class. Again, the problem has occurred both with VE7CC on and off. Let me add my thanks to all who have responded to my question! 73, Bill, K8TE From: Joe Subich, W4TV-4 [via Elecraft] [mailto:ml-node+s365791n7607374h49 at n2.nabble.com] Sent: Thursday, September 10, 2015 6:52 AM To: K8TE Subject: Re: Mic gain goes to zero using N1MM > In my shack I use LP-Bridge to provide virtual serial ports, > including one to the K3.

As far as swapping the options into a new K3S-10, I would suggest that although the KPA3 may swap over, I would not attempt it. The new KPA3 is a total redesign forced because the PA transistors used originally are no longer available, and the new RF board was optimized to work with the new KPA3A. So if you are swapping, I would recommend that you start with the K3S-100 rather than the 10. Besides you will probably find more buyers for your K3-100 than if you offer it as a K3-10. The subreceiver has not changed from the K3 to the K3S, so you can easily swap it. If you have found you have too many filters, then you can leave some of the filters in your K3 for whomever would buy it. For the KAT3A, if you do not have resonant antennas that would benefit from the bypass relay, then you could swap your existing KAT3 to the new K3S, but for sale of your K3, many potential buyers would want the KAT3, so if it were mine, I would be reluctant to remove it. The decision is yours to make, but if it were mine, I would simply upgrade to the KXV3B (I already have done that) and wait until the KIO3A is available if you want the USB interface (I am happy with the existing RS-232 interface), then upgrade your existing K3. Since you have already changed to the KSYN3A, you have already achieved the major part of the performance improvement. OTOH, if you are into 'eye candy' and like the new bezel and the feel of the new knob, there is only one choice - get the K3S. 73, Don W3FPR On 9/10/2015 9:33 AM, dhhdeh at comcast.net wrote: > Here?s my dilemma.

Hi All, I?m the owner of a 7? year old K3 fitted with a sub-receiver, DVR, TCXO option, 100W PA, Auto-tuner and probably too many IF filters (as I have belatedly discovered). I added the two new KSYN3A boards back in the spring which has produced an excellent improvement to both receivers?.then a few weeks after that Elecraft announces the K3S?.grrrrrr My K3 has been updated with all the hardware mods.

So far it has given me flawless service though not at all stressed (no contesting, field days, SOTA, motocross mobile, lending to friends, pawn shops, etc.) Here?s my dilemma.

Do I sell it outright (along with a lot of other stuff to raise the $$) and buy a completely new, comparable K3S or do I buy a new bare-bones K3S-10 and transplant the options I can from my older K3 to a new K3S? There?s a big $$ consideration in this decision. But first, I am interested in opinions on any K3S performance improvements. For those of you who have gone from a K3 to a K3S, I would be interested in your observations and opinions of the following: 1. Does the new K3S DSP board significantly improve the audio coming out external speakers? 2. Aside from new attenuator steps, what improvements do you notice improvement with the revised main RF board? I?m really curious about this as it?s the biggest piece of the K3 that cannot be updated. 3. Aside from a new ATU bypass relay, is there any different performance with the KAT3A auto-tuner? 4. Aside from new PA devices, any noticeable changes/improvements to the 100w PA? 5. Is the only thing revised in the KRX3A sub-receiver the addition of the new KSYN3A board? The KIO3B, KXV3B and KBPF3A upgrades are of lesser importance to me in this decision process because of my operating style. BTW, I liked the old K3 bezel appearance better than the K3S especially after I had my K3 bezel custom engraved by WB2ART (just razzing you Wayne). I?d be interested in hearing about your experiences and/or opinions on the above. To keep the mail volume low, perhaps replying to me off list would be best. n1lq at arrl.net I?ll let you decide on how to proceed.

First I have a K3 fully configured, including the new synth board, and have no plans to go to a K3S. It seems to me that currently the K3S will not do much more than a K3 with the new synth board (in particular!) and perhaps some of the other options of the K3S. But the future may show something different. I suspect there may be future K3S enhancements which are not compatible with the K3. Only Elecraft can possibly know if that is true, but I suspect that will be the case. At this point my K3 does all I need in a main-station transceiver. So I'm standing pat. 73, Phil W7OX On 9/10/15 7:32 AM, ae4pb at carolinaheli.com wrote: > I'm a soon to be future owner of a K3S.

I do plan to to add the rest as they become available this year (well, I don?t plan to upgrade the 100W amp/tuner module unless the current boards crater). Yes, I know the new RF board won?t be made available for the K3. And I suppose if someone shows an order of magnitude improvement in some essential performance number attributed to that I might reconsider. But for now, I see no reason to sell off what I have and spend more money purchasing what is essentially the same radio. I?ll more likely than not bite at whatever the ?next gen?

IVE SEEN MANY GOOD RECOMMENDATIONS. I WOULD PERSONALLY RECOMMEND THE SAMLEX SEC- 1235 OR SEC-1235M. THIS IS A SWITCHING SUPPLY THAT I HAVE BEEN USING FOR SEVERAL YEARS WITH NO PROBLEMS AND BEST OF ALL NO NOISE INTO MY RIG. THIS SUPPLY NOT ONLY RUNS MY KX3 BUT A TWO METER RIG AND SCANNER AND IT LOAFS ALONG. ABOUT A MONTH AGO IT SUDDENLY FAILED. I CONTACTED THE COMPANY. I FOUND OUT THAT MY UNIT WAS OUT OF WARRANTY. FURTHER COMMUNICATIONS WITH THE COMPANY DEMONSTRATED TO ME THAT THEY ARE ON PAR WITH THE BEST CUSTOMER SERVICE ORIENTED COMPANIES THAT I HAVE EVER DEALT WITH. THEY TREATED ME LIKE I WAS A GIANT CORPORATE BUYER INSTEAD OF A LOWLY HAM WHO HAD A SMALL POWER SUPPLY. THEY BENT OVER BACKWARDS TO HELP ME GET BACK IN SERVICE RAPIDLY. FIRST THEY FURNISHED ME A SCHEMATIC IN CASE I WANTED TO TRY AND HAVE MY UNIT REPAIRED. IT ENDED UP WITH THEM OFFERING ME A REFURBISHED UNIT AT A WONDERFULLY LOW PRICE. TO ME HAVING A COMPANY THAT IS WILLING TO FULLY STAND BEHIND THEIR PRODUCTS IS GOLDEN. AS I SAID THEY WERE WONDERFUL TO ME AND WERE KNOWLEDGEABLE AND IMMEDIATELY TOOK OWNERSHIP OF MY PROBLEM AND MADE EVERY EFFORT TO SOLVE MY PROBLEM. WE HAVE ALL COME TO APPRECIATE THIS SERVICE AND TREATMENT FROM ELECRAFT AND ITS REFRESHING TO KNOW THAT THERE IS ANOTHER COMPANY OUT THERE DOING THE SAME.

This would be a FURTHER improvement to the already common field day "one K3 on CW, one K3 on SSB, on the same band, don't hear each other", etc. Practically, this might mean operation at multi/x contest stations to within 5/10 kHz or less with some attention to RX antenna separation from TX antenna and not burning up K3 front ends. We will know more about this during/after the upcoming 2015/16 contest season. 8) NB and NR are better/clearer. (Egads, but I understand why.) I have not gotten the open time to get all the "S" mods done. I have them on hand, but I have to finish it all in a single stretch of bench time to keep from losing and forgetting stuff. But given the above, I fully expect diversity to improve. Any ole week now, I expect to be able to show P3 display of new birdies displayed at 160m high noon. There is a full depth, an ocean deep layer of discreet cr*p from Raleigh environs, and I expect to be able to hear that discreet crap a lot clearer. Why should anyone care? I will also expect to be able to hear a little farther down into the stuff coming in on the EU oriented 5 element monster quad at NY4A. Maybe that largely uncopiable layer of Russian "peepers" on 40 will wind up in the log. We will see. Going forward, my money is on the idea that after a while, the first question asked about a used K3 will be whether they have the SYN3A board(s), or have the "S" mods. A "yes" will command a higher price. Face it folks, the old syns are obsolete. If that doesn't affect your personal operations, that's cool, save your money, but the main deal will be whether the K3 has the SYN3A board(s) and the new DSP/audio board. Just my opinion, but with Yakencom, something the level of the SYN3A + DSP/audio improvements will ALWAYS cost you the bucks of a brand new model, maybe a new model line. There is actually very little of the K3S change lineup that will not ultimately be available for a K3 owner. Elecraft has done it so you can pursue EITHER path, as you wish, and pick and choose. And there are some who are complaining this makes it too difficult to figure out. Ah, serving the public...always the tanner of hides and progenitor of thick skins. At some point I decided to wind up with a pair of K3's. As it stands now, it will be my fully modded kit K3 #1239 and a new factory K3S, both with diversity equipping. The K3 will be the take-with rig and the "S" will never leave the shack. I will be selling some stuff to get that done. Never been motivated that way before. Not doing 160-40 without diversity ever again. With the SYN3A and DSP/audio board upgrades, I expect an improvement in clarity in diversity mode. 8) above is the final clue to that. If a significant degree of fully random phase noise is eliminated with circuit improvements elsewhere, the depth of NR, NB must improve. That is because the SYN phase noise is FM style **modulation** of ALL the frequency converted signals. The old synthesizer phase noise MODULATES the band noise and makes the result broader and harder to process to depth. The SYN3A mod will remove a layer of stuff at the noise level that our brains will NOT have to discern their way through in resolving the diversity sound stage. There are a lot of K3 owners that seemingly would be as well served by lesser rigs given their description of typical use. Some I know personally and they are NOT latest and greatest hounds. One fella simply said "I always buy quality. Always works out best in the end." A historical summary of operators at the NY4A multi/multi indicated that their 11 FT1000MP's all the rage at one time were gradually replaced by 14 K3's and one Orion II. Now it would seem the Orion is about to be replaced by a K3S. Although there certainly is a "latest and greatest" crowd here on the reflector, that does not explain the remarkable coincidence of the NY4A ops, none of whom will ever put up with being told what to do and buy, and who to a man despise KoolAid. That particular crowd and their close buddies have tried TS590x, various Flex models, Ten Tec, the Icoms, but not the Yaesu 5000. I asked the most prolific rig sampler why not the Yaesu 5000 and he said too big, too expensive, and only Elecraft has Elecraft philosophy and service. All taken together, the collection of mods is spectacular. I do note that those who have NASCAR grade conveyances parked in their driveway probably will not notice this grade of improvement in the weekly 3/4 mile trip to the local Target for groceries. But those who push K3's to the limit are already seeing a lot of improvement in the mods/K3S. And what is the K3S? It is the inheritor of eight years of fix-it, improve-it, and new feature water under the bridge, both hardware and firmware, and some of them really serious fixes. I could always say you should buy a K3. When all they are now selling new is a K3S with all that stuff already done, just do it. 73, Guy K2AV On Thu, Sep 10, 2015 at 2:28 PM, Doug Turnbull wrote: > Arnie, > Elecraft has already blown every other DSP based radio out of the water. > They keep improving to stay that way.

When I return to a previously tuned band frequency on the LDG all I hear are a click or two and it is there. The K3's tuner rattles and carries on for quite a bit longer seemingly needing to find the match all over again as though there is no memory in the tuner.

Two of my K3s date from 2007 and have two RX, a third from about 2009 with single RX. I put the new synth boards in all three. For convenience, I changed out the transverter boards in the older radios to get the new preamp. For an investment of about $1K, I have upgraded three 8 year old rigs to 90% of their latest model. I have no intention of selling anything. I have no interest in the new KIO3B unless they have fixed the Pin One Problems. The USB port doesn't interest me.

In-Reply-To: References: Message-ID: <55F20941.5030509@embarqmail.com> Rick, Certainly there is an easy way. Remove the ACC connector and measure the DC voltages with your DMM at the pins for the Band Data. Refer to the chart on page 19 of the manual. Select 12 meters, or 10 meters or 6 meters and the BAND 3 output should read 5 volts if the pullup resistors are installed. Similarly, select 17 meters and the BAND 2, BAND 1 and BAND 0 pins should read 5 volts if the pullup resistors are installed. If you find zero volts (or a low voltage) reading in the above tests, the pullup resistors are not installed. Given your problem statement (relays not being pulled in), I suspect your problem is not with pullup resistors, but something else associated with your band decoder. The band data voltages should not be used to source current in order to pull in relays. Some intermittent decoder and relay driver circuits should be in place - the relay drivers in your decoder box should be doing the work of pulling in the relays. If you have problems with insufficient voltage for pulling in the relays, look in your decoder box for the problem. 73, Don W3FPR On 9/10/2015 6:14 PM, Rick Tavan N6XI wrote: > Is there an easy way to determine whether a KIO3 is a B model with pullup > resistors on the band data lines without pulling the rig and opening it up? > > Since a recent change in band decoders, I've been troubled by > intermittently insufficient voltage to pull in my antenna relays and I'm > wondering if perhaps it originates with band data not being pulled up. > > Thanks & 73, > > /Rick > From ar at dseven.org Thu Sep 10 18:57:35 2015 From: ar at dseven.org (iain macdonnell - N6ML) Date: Thu, 10 Sep 2015 15:57:35 -0700 Subject: [Elecraft] Napple Updates?

I have a K3 with the internal tuner. I also have the KAT500. I have thousands of QSOs on those devices, and the tuners ALWAYS go back to the memorized setting so fast I may sometimes not even notice that it changed... but when I gift it RF I see that the SWR is right where I hoped it would be. My experience was exactly the same with the KX3 that I borrowed from a friend in the Summer of 2013, when I made hundreds of QSOs on 80 through 10 meters into a 125' end fed wire. I have far less experience with LDG or SGC tuners, but if you have an Elecraft tuner that does not do the job almost instantly, then I suspect there is something wrong, either in the setup, the initial training of the tuner, or in the device itself. If a person wants an external tuner of Elecraft quality, I suggest getting the KAT500. It is more money than tuners rated for less power, but I have a friend who got one to use with his IC756ProIII and an SGC amp. It replaced his LDG-1000 PRO which fried (for reasons I am not aware of). I felt that the KAT500 matched his antennas better and faster than the internal tuner in the '756... but admit, that may have been prejudice on my part... I am the one who talked him into the KAT500. 73 to all, Dave - K9FN On Thu, Sep 10, 2015 at 6:17 PM, Gregory Schippers wrote: > Nate- OP referenced tuner in kX3, not K3.

The "automatic" part means that once tuned, the tuner will remember the L/C settings for that frequency and will return to it when you move the VFO to that band segment. That means that your transmission is not interrupted by the tuner attempting to tune while you are transmitting. The KXAT1 and KAT500 are the exception, if placed in "AUTO" it will attempt to tune when it senses a high SWR. On SSB particularly, that may initiate a false SWR reading. The instructions for the KXAT1 tell you to "train the tuner" to your antenna and then change it to "MAN" mode so it does not respond to those false SWR indications. 73, Don W3FPR On 9/10/2015 9:36 PM, Stephen Shearer wrote: > I can't speak for the K3, but my KX3 only tunes when I ask (push a > button) but my LDG is an auto tuner.

Why do we do it? Besides esthetics there are two main reasons. 1} To get rid of flux which may be reactive with RF and reflow where it isn't wanted... like into contacts, mechanical devices, and shaft encoders. 2} To get rid of ionic compounds which may lead to circuit leakage and insulation breakdown. For many years one of the better ways to clean boards involved Freon vapor degreasers. They used a compound known as Freon TE which contained Freon and ethanol. Then, as Wes mentioned, the EPA banded Freon. Without Freon, which acted like the fire extinguisher Halon, ethanol became explosive so degreasers were banded. There are many types of fluxes. Most of the industry switched its machine soldering to water soluble fluxes so only soap and water were needed for board cleanup. Water was in some ways superior to ethanol because ethanol is a non-polar solvent meaning it does not capture ions, the types of atoms that support electron flow (see 2} above). However the most popular cored solders used in hand soldering are still rosin flux based so alcohol is still very viable for hand spot cleaning of PCBs. Ethanol and isopropanol are both good flux cleaners but perhaps are not as good as some other solvents as degreasers and of course they do not remove ions as water does. It should be mentioned that both pure ethanol and isopropanol are flammable meaning they burn with a dull blue flame. They don't burn like gasoline but many gasolines do contain ethanol. I have heard it said here to use only pure alcohol. That's fine if you are drinking the stuff otherwise the reasoning for this proclamation is somewhat nebulous. If you are letting alcohol or any other solvent evaporate on the PCB you are NOT REMOVING FLUX. You are just moving the flux around. After absorbing the flux in alcohol you need to remove it wet (i.e. as a liquid). There are a number of ways for doing this but perhaps the easiest is to blot with a paper towel. The alcohol with flux will be pulled in and trapped in the paper fibers. I like compressed air too. Now back to purity issues. Using a 91/09 or 70/30 isopropanol, commonly referred to as rubbing alcohol, adds water to the process. The water slows the evaporation rate, collects ions, and makes it difficult or impossible to burn. However 50/50 dilutes the alcohol so much that is no longer effective so it is not recommended. So a little water is a good thing; too much you drown. Don't forget your board has seen lots of water during the manufacturing cycle. Don't be afraid of a little more water but of course don't operate anything without thoroughly drying. 73, Fred, AE6QL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of David Woolley Sent: Thursday, September 10, 2015 4:52 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KSYN3A mod problem Ethanol and Isopropyl Alcohol are almost as polar as water.

The meaning in this sense is that it will not seek to find a new L/C combination - you must tap the TUNE button for that to happen. It will automatically switch to the last remembered L/C combination. 73, Don W3FPR On 9/11/2015 9:24 AM, Pierfrancesco Caci wrote: >>>>>> "Don" == Don Wilhelm writes: > > Don> Most (if not all) the Elecraft "auto tuners" will not tune unless > Don> commanded by a tap of the TUNE button. > > wasn't one of the tuners (maybe the KAT500) enhanced to track VFO also > in RX, by using the AUX connection? > From w0fm at swbell.net Fri Sep 11 11:02:15 2015 From: w0fm at swbell.net (Terry Schieler) Date: Fri, 11 Sep 2015 10:02:15 -0500 Subject: [Elecraft] Elecraft FS: K3/100, Mint Message-ID: <003d01d0eca2$d9167890$8b4369b0$@net> FS: K3/100, (#474 from kit).

When I got my K3, I also owned an Icom 756 Pro III. My plan was to keep both ? I am the original owner of the Pro III and I had this feeling that every time I sold a radio I regretted the decision. Right from the start I did a detailed comparison and being mostly interested in CW, my comparison tests were all about CW. Picking out weak signals ? absolutely no contest. I could copy a signal Q5 on the K3 that I couldn?t even hear on the Pro III even though both were using the same antenna (switching back and forth). Pulling out a signal amongst QRM and QRN ? absolutely no contest. The filters on the K3 made a big difference that could not be matched by the filters on the Pro III. So, I became hooked on the K3. When the P3 came out, since I was a lover of the spectrum display on the Pro III, I bought it right away. Now, the die was cast. The Pro III took up valuable room in the shack and collected worthless dust I didn?t want to clean. This went on for two years of total non-use. Finally, I decided to sell. Turned on the Pro III for the first time in two years to test it out and then sold it within one day via Craigslist for $1850 (two years ago). No, after two years, I have not regretted my decision to sell the Pro III. I am done with Icom unless they come out with something really great and different (despite the fact that Icom HQ (USA) and their main service shop is just five blocks from my home QTH). Note: if you operate SSB only (or, mostly) then the performance differences between the Icom Pro III and the K3 are probably less dramatic although I never did any comparison tests in SSB mode. 73, phil, K7PEH > On Sep 11, 2015, at 9:41 AM, Tom Fitzgerald via Elecraft wrote: > > > I have both radios..bought both new...I'd advise you to keep your Pro III & add a K3 or K3s but if that's not an option then I would say keep your Pro III & wait a bit longer for the inevitable "next incarnation" of the K3...possibly a K4.

This means you can simply use the P3 utility and press the "Copy new files from Elecraft" to download the firmware to your computer. *It's recommended that all customers and particularly those owning an SVGA card, download and install the latest P3 Utility (1.15.8.28). ** * Release notes for 1.54/1.25 : *MCU 01.54 / 8-14-2015* * Added new transmit monitor maximum power meter scales of 160W and 1600W. * When the P3 with transmit monitor is connected to a K3, the P3 goes into transmit mode only when commanded by the K3 and not when RF power is detected.This prevents false triggering when RF power is present from another transmitter using a nearby antenna. Bug fixes: * Noise blanker settings are sent immediately to the SVGA upon band changes. * Noise blanker settings are saved in non-volatile memory when set via RS-232 commands. * Reference level labels are properly rounded. * The SVGA WfEn "Track main" mode name was changed to "Same as main".This mode now initializes properly upon power-up and menu items to adjust the SVGA waterfall values are inhibited when in this mode. * The SVGA waterfall height is limited to avoid interfering with the NB icon when adjusted via the main waterfall menu item while in "Same as main" mode. * On the main display, menu labels are prevented from impinging on the waterfall area if the transmit monitor meters are enabled, the function key labels are enabled, and the waterfall size is set too high. * Prevents the possibility that FN1 could get re-defined during a firmware update. * Eliminates extraneous text on the display when activating certain menu functions when the TX monitor coupler is not present or the SVGA waterfall is set to "Same as main". * When no K3 is present, the transmit monitor uses a higher trigger level with the VHF coupler to sense when to go to transmit mode, in order to prevent false triggering. *P3SVGA 01.25 / 08-19-2015* ** * Added Noise Blanker. * Developed a faster method of detecting K3 transmit/receive state changes. * Added data terminal ?send on space? to the available data TX modes. * Added replay of keyboard input using Ctrl-Alt-R.Ctrl-C will clear replay buffer. * Added ?\r? to embed a CR in text message. Use ?\\? to send a single ?\?. * Added ?\c? to embed an incrementing serial counter in a text message.Clearing/presetting counter may be done in the setup screen (Ctrl-Alt-S). * Text messages sent in data terminal mode now respect the mode setting (VOX, CR, ^T). * Fixed a bug in data terminal mode that was causing the time-out to not reset correctly. * Fixed a bug in data terminal mode that was causing non-existent characters to be retrieved and sent.Also fixes a bug of missing characters. * Fixed a problem that caused some SVGA boards to not initialize correctly from P3 commands at boot. * Added waterfall cursors, these display exactly as they do on the P3 screen. 73, Paul -- Paul Saffren - N6HZ Project Manager Elecraft Inc. www.elecraft.com From elecraft at mailman.qth.net Fri Sep 11 15:03:29 2015 From: elecraft at mailman.qth.net (George Fritkin via Elecraft) Date: Fri, 11 Sep 2015 12:03:29 -0700 Subject: [Elecraft] K3 vs K3s..."to be or not to be an "s" In-Reply-To: <3A1B9D2F-6A36-4E70-8219-E4D08B7A09F6@yahoo.com> References: <3A1B9D2F-6A36-4E70-8219-E4D08B7A09F6@yahoo.com> Message-ID: Then again we can all live the life of poverty.

Answers are in the manuals for the two radios. If you didn't receive the manuals when you bought the radios, you can download them as pdf files. 73, Jim K9YC From k6dgw at foothill.net Fri Sep 11 16:22:41 2015 From: k6dgw at foothill.net (Fred Jensen) Date: Fri, 11 Sep 2015 13:22:41 -0700 Subject: [Elecraft] [K2] LiFePO4 replacement for internal SLA battery in K2 In-Reply-To: <55F311BF.9030505@verizon.net> References: <55F311BF.9030505@verizon.net> Message-ID: <55F33811.7000406@foothill.net> On 9/11/2015 10:39 AM, Robert G Strickland wrote: > Steve... > Thanks for the info and for your effort in getting this item up and > running.

Don't know about your first question, but LiFePO4's require a cell balancing charger. Charging a 4S1P LiFePO4 on the same two wires you discharge it with will generally really reduce the battery life. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org From w6jhb at me.com Fri Sep 11 16:23:51 2015 From: w6jhb at me.com (James Bennett) Date: Fri, 11 Sep 2015 13:23:51 -0700 Subject: [Elecraft] K3 to Pro III, my thoughts to Jeff, wb0m In-Reply-To: References: Message-ID: <335F4161-49C6-4F36-AD49-2C4C5C79B36E@me.com> Inferring that those of who have stated that we prefer the K3 over the 756 ProIII to be dunces is uncalled for and not very professional.

Of course, smaller scale of market does force a different business model. OTOH -- Whatever you think of Apple's approach, it sure works for them!

Sorta makes you wonder why they just didn't make the damn thing that way in the first place, I think we all know why. I've owned all the iPhones from the very first one up to the recently new 6 Plus w/128gig hard drive & now the 6s Plus is out! Honestly!!!??? I've had gripes about all of them, use to be size (to small), then camera resolution, then software bugs & the OS, etcetera etcetera etcetera. Getting off topic...back to the radio...I have 3 radios inline including a mid serial number 3,000 something K3. I paid tooooooo damn much for all of them and am quite sure I can survive without the latest & greatest version of the K3...the "s" line...ya just know that some day real soon there will be the next latest & greatest K4 or some nonsense out making the new K3s old news. I can think of about a hundred other things I'd rather do with the $$$$ than burn it on another ham radio but then again, ham radio isn't my life or my passion, it's just a hobby. In the end it's a personal decision you have to make based on many factors. Do you really need this new version or just want it? It sounds like you have a great radio now...take a trip to the South Pacific with the wife instead is my advice (at least one of you could go for the same money maybe :), avoid getting that feeling of wondering why you blew perfectly good money on something you really didn't need in the first place. I find that it's the "wanting" that's the real drug, after you get the new "thing", it's newness wears off pretty quick & then it's just the same old same old again. Skip this version and wait for the next one is probably good advice too, maybe the best advice, you know that it's already being thought about & it is after all...inevitable. I'm staying pat until many of the physical features of the radio are addressed...& they will be...eventually, the performance upgrades will be in that future radio too. Don't get on the merry-go-round as I did with all the different models of the iPhone, it's simply a waste of perfectly good money better spent elsewhere or even invested and or saved.

Date: Fri, 11 Sep 2015 22:02:11 -0400 Subject: [Elecraft] [K2] LiFePO4 replacement for internal SLA battery in K2 Message-ID: I have recently received the LiFePO4 battery pack I ordered for the K2 and which I mentioned in an earlier posting. Upon receipt I checked it out mechanically. It looks very nicely made. The supplied pigtail is terminated with the mating internal K2 Molex DC connector. I charged the new pack using a precision lab type CC/CV power source and it accepted a full charge, according to my expectations. After 48 hours, the pack, with no load applied, dropped about 0.6V also as expected. I did not yet try to install the new pack in the K2 but the micrometer says that it will perfectly fit the Elecraft KBT2 bracket for which the new pack was purposefully designed. This pack *is *equipped with a protection card, limiting short circuit current, over voltage, and under-voltage (low voltage disconnect); the latter is to prevent ruining the pack by leaving it across a load. The pack does *not* have a balancer built in. I recognize the possibility that this can reduce the ultimate pack capacity over time, but I have also looked into the matter in some depth (and I have a background commercially in both primary and secondary cell / pack design trade-offs). I feel comfortable with my decision to not equip this pack with a balancer, which among other things would have made the physical dimensions of the pack not match what was needed in this radio. The pack cannot be charged correctly (in most all states of discharge) using a conventional constant-voltage external power supply on the K2. Instead, after I retire the SLA, I will use a CC/CV type charger intended for the purpose. Further, the LiFePO4 pack should not be floated indefinitely in CV mode. The primary challenge I see with the setup as it is shipped from Batteryspace is that the pack's stock cabling is not configured for for the KBT2 battery disconnect switch to be placed in series with the pack. This switch would allow me to operate the K2 from a conventional power source such as the Pro Audio Engineering PAE-KX33 unit. To get around this problem, I will use suitable connectors and arrange for the KBT2 power switch to be inserted in the (+) lead between the new pack and its Molex fitting. I will also inform the very helpful gentleman at Batteryspace about a good way to redesign his pigtail to make this work for other people. I do not wish to (and will not) add a separate battery charge jack on the radio. The advantages of the SLA are that it is rather robust, can float charge from the typical power source, and is relatively inexpensive. Weight may or may not be an advantage. The SLA certainly gives the K2 some heft and a solid feel. But it's not light and portable use often requires lugging the radio about. The advantages of the LiFePO4 pack are significantly longer run time from a charge (I am thinking 2x), and an anticipated much longer service life. I will report once more sometime in the future after I have suitable real-world experience using the new pack. It may be some time before I make this report; in relative terms however, it won't take too long since I've been on this reflector daily for about 16 years. ;-) 73 Steve KZ1X From n6kr at elecraft.com Fri Sep 11 22:18:51 2015 From: n6kr at elecraft.com (Wayne Burdick) Date: Fri, 11 Sep 2015 19:18:51 -0700 Subject: [Elecraft] Elecraft SP3 External Speaker!

I no longer do. It sits in a desk drawer, unused, replaced by a Samsung Galaxy running Android. The reason is not OT - it is in stark contrast with what Elecraft does. About 18 months ago I made the mistake of accepting a prompt from Apple to ?update? the OS on my iPhone. I did so. Big mistake. Immediately half of the apps ceased to work, and what did work had slowed down noticeably. I tried to revert to the original OS but learned that doing so was impossible - Apple had made that so. Commentary on the Internet at the time suggested what I suspected - that the upgraded OS was designed for the new iPhone 5 (or whatever was then a number or two ahead of mine); and that its backwards suitability to the earlier hardware was knowingly abysmal - a strategy for convincing owners of older iPhones to upgrade their hardware, at considerable cost. I don?t know enough about that world to know if the allegation was true; but the effect certainly was. So now I own a Samsung. Never again an iPhone. One of the many great things about Elecraft gear is that the opposite occurs, at least during all the years that I have been in the owner group. Updates are designed for and suitable for the old equipment; and even makeovers are designed to allow upgrades almost to match, as in the K3 and the K3S. That design strategy adds significant value to Elecraft gear from the moment it?s purchased. Intentional obsolescence as a marketing strategy, by contrast, reduces initial value. Long live the Elecraft approach.

But if you send K22; then some commands will behave differently, including the PC command, which goes from 1-watt increments to 0.1-W increments. K22 mode also adds a 4th digit to the PC command.

I've been using my K2 for extended operations (8 hours) from SOTA summits and have been lugging a 5 pound 7AH SLA. Needless to say I'm very interested in going on a weight diet for the K2! I've had good success using external 1AH LiPOs for smaller rigs (ATS-3 and Weber Tri-Bander) but they're CW only and band limited. They're also very inflexible for quick band/mode, where the K2 shines. I've had zero problems with LiPOs but I religiously charge and store them per manufacturer's specs. I'm also a little leery of internal batteries of any type. Since I already have a balancing charger for LiPOs, I've been considering a larger capacity LiPO (e.g. 4.5 AH available on eBay for <$25) for the K2. For comparison, this battery weighs <12 ounces versus the 5 pound 7 AH SLA, so it weighs 86% less and probably has sufficient life for most of my operations. I'd be interested to hear any comments from others about any leakage problems with internal batteries. 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-LiFePO4-replacement-for-internal-SLA-battery-in-K2-tp7607467p7607473.html Sent from the Elecraft mailing list archive at Nabble.com.

Date: Sat, 12 Sep 2015 11:37:17 -0400 Subject: [Elecraft] [K2] LiFePO4 replacement for internal SLA battery in K2 Message-ID: I had strongly considered the LiPo type secondary-cell power packaging option and rejected it. Energy density in that chemistry/package is amazing of course. But that equation is also true of a bomb. I have no problem with the LiPo in my iPad, Galaxy S5 phone, and laptop, so, it's not a blind bias. It doesn't take too much YouTube searching to find dramatic examples of LiPo powered RC vehicles and the like bursting into flames. There's a good reason that *all* these lithium cells are considered hazmat now, not just the lithium thionyl chloride ones ... on failure, those burn and emit nerve gas; they are Class 9 hazmat! They are also not rechargeable anyway. Because this particular power pack would be fully enclosed in the metal-cased K2, and would be in the 9 ampere-hour range in this desired form factor ... if such a LiPo pack decided to self-immolate, the rig would not only be destroyed but I'd have a real secondary incendiary hazard on my hands. The charging, power regulation and protective circuitry, etc., needed to use the LiPo chemistry/packaging inside a K2 took that consideration off the table for me. YMMV. The 'safe-failure-mode' secondary-cell chemistries I considered were NiMH and LiFePO4. The NiMH almost won. By the way, I have the special spot-welder device and strap/bracket supplies needed to fabricate my own packs. Extensive experimenting with NiMH cells really had me convinced to go that way for some time. Then, I got some newer LiFePO4 cells and also some new LiCoO2 cells, and started the "2015 edition" revisiting of the selection analysis. I had last looked at the issue in 2010. It didn't take long before my own clumsiness lit one of the 18650-size LiCoO2 cells up. I caught the mistake just as it was about to get really serious. Lesson learned. Now I know why the manufacturers of those include the built-in-per-cell safety circuit option! The cells I tried were the 'raw' and unprotected type, selected purposefully so as to not have the size, cost, and loss of the protective circuitry. For these and other reasons, this chemistry/packaging option was rejected for the particular use-case. I could not achieve a better-than-the-SLA result with NiMH. Hope my describing a portion of the ferreting process in a bit more depth is of use to others. The K2 is a remarkably competent field radio. Being able to actually use it in the field, conveniently, makes my now-teenage rig all the more valuable to me. Having a modern internal power source will just be icing on an already tasty cake. 73 Steve KZ1X From elecraft at mailman.qth.net Sat Sep 12 12:11:51 2015 From: elecraft at mailman.qth.net (edeveloper_1--- via Elecraft) Date: Sat, 12 Sep 2015 16:11:51 +0000 (UTC) Subject: [Elecraft] Elecraft SP3 External Speaker details Message-ID: <157147629.1485778.1442074311951.JavaMail.yahoo@mail.yahoo.com> Hi Wayne, Thanks for the update - from the photos on Twitter it looks like a very nice unit.

We'll have a product brochure and photos soon, but here's a brief list of features: - styled to match the Elecraft K-Line - same size as the Elecraft P3 Panadapter, with matching fold-up tilt stand - works with any transceiver, but optimized for use with the K3 and K3S - custom-built, high-quality 4-ohm oval speaker with outstanding passband characteristics - A/B source selector switch - two jacks for mono or stereo input sources, and one mono extension output, allowing ? convenient switching of the following configurations: ? - one transceiver, one speaker ? - two transceivers, one speaker, selected by A/B switch ? - one transceiver, two speakers (stereo) ? - two transceivers, two speakers, selected by A/B switch (stereo) The SP3 will be sold assembled/tested only. 73, Wayne N6KR From n6kr at elecraft.com Sat Sep 12 12:16:16 2015 From: n6kr at elecraft.com (Wayne Burdick) Date: Sat, 12 Sep 2015 09:16:16 -0700 Subject: [Elecraft] Switching the K3 or K3S to 600 meters with a macro Message-ID: <5698EB93-DE12-4D06-9B0D-DEE0118F55B3@elecraft.com> Hi all, Using 600 meters (~472 kHz) on the K3 or K3S with an external transverter requires setting the CONFIG:KXV3 menu entry to TEST mode. This routes the RX and TX signals through the XVTR IN and OUT jacks. You then need to switch to 160 meters, select the desired mode, tune in VFO A, etc. An alternative to performing all of this setup each time is to set up a pair of programmable switch macros to go from regular bands to 600 meters (etc.). Example: MN051;UP;MN255;BN00; The above macro selects the CONFIG:KXV3 menu entry, changes its setting from NOR to TEST (simulating moving VFO A "UP" 1 tic), exits the menu, and selects band 0 (160 m). The band-change command (BN00) could be replaced with an FA command to select a specific frequency, along with a mode setup (MD), preamp setup (PA), attenuator setup (RA), etc. Here's a complementary macro to restore CONFIG:KXV3 to NOR mode. It also places the rig on 20 meters (BN05): MN051;UP;UP;DN;MN255;BN05; Note that I used "UP" twice, then one "DN" (down), to make sure the KXV3 ends up in NOR mode even if had already been set to NOR. If I had just used "DN" instead of "UP;UP;DN;", repeated execution of the macro would put the KRX3 into NOT INST mode (not installed). The macros above can be assigned to two of the radio's 10 programmable switches using K3 Utility. See the CONFIG:MACRO menu entry description. If you wanted to use just a single switch to toggle between 600 meters and some other band (or just toggle the KXV3 menu entry between NOR and TEST), you could use one self-modifying macro. Below is a posting by Fred Cady (KE7X) that describes the general method for doing this. 73, Wayne N6KR * * * I don't know who first came up with this clever idea but here is the concept and an example: The concept is this: * Program a macro, say MACRO 7, and assign it to a function key, say PF2, to perform the first of sequence of commands. End the macro definition by assigning PF2 to the next macro command sequence, say MACRO 8. * Program MACRO 8 to do the second sequence of commands and end it by assigning PF2 to perform MACRO 7. Here is how it would work to use PF2 to enter the Split mode using the dual-watch receiver with the first hold, and then to exit Split mode with the second hold of PF2. * Using the Utility, assign MACRO 7 to: SWT25;SWT25;FT0;SB1;UP7;MN110;SWT33;SWH26;MN255; The first five enter dual-watch and QSY VFO A up 5. The other commands assign MACRO 8 to PF2: MN110; Enter the MACRO x menu (equivalent to holding MENU and rotating VFO B to MACRO x). SWT33; Tap the 8 switch. SWH26; Hold PF2. (This assigns PF2 to the commands in MACRO 8.) MN255; Exit menu mode. Now, * Assign MACRO 8 to: SWT25;SWT25;FT0;SB0;MN110;SWT32;SWH26;MN255; SWT32; Tap the 7 switch. SWH26; Hold PF2. (This assigns PF2 to the commands stored in MACRO 7.) Send the macros to the K3 using the K3 utility and then enter the MACRO 7 menu and hold PF2 to assign it to enter Split mode. The next PF2 hold will take us out of Split. Subsequent holds toggle back and forth. Neato, eh?

There are mfrs of well protected LiFePO4 battery packs. Two I found are Battery Space and Bioenno Power. Both make packs in a wide variety of shapes to fit in the space available in existing products. They include the circuitry inside the pack required to equalize charge and avoid unsafe conditions. These batteries are not cheap, but you'll appreciate the increased energy density. If you're concerned about fitting the battery inside the radio, buy a battery and use it outboard. I bought a 20Ah battery from Bioenno Power. It came with two connectors, one a concentric connector for charging, the other a Power Pole. I'm past the backpacking stage, but I bought the battery to support a 6M grid trip to CM79 by a younger ham. He really appreciated the reduced weight. Both of these companies sell 12V LiFePO4 batteries range from 3Ah to 125Ah. 73, Jim K9YC From fptownsend at earthlink.net Sat Sep 12 13:14:37 2015 From: fptownsend at earthlink.net (Fred Townsend) Date: Sat, 12 Sep 2015 10:14:37 -0700 Subject: [Elecraft] Elecraft SP3 External Speaker!

I like both radios & don't want to start an argument about this radio vs that radio yet again...there have been zillions of such debates already, you can spend hours reading them online. If your Pro III is as flawless as mine (& one of the last ones produced) and not used that often (I have 3 radios which reduces wear & tear on any single radio), I would think very long & hard before parting with it. Hopefully you've sat down in front of a K3 and operated it so that your not surprised when you open the box, if you haven't done that...you need to do so. I know some that bought the radio and sold it soon after buying it because it wasn't what they expected. For those that tell you that "you won't regret it", maybe they really do regret parting with their Pro III but just want some company in the dunces corner! I say that you may very definitely regret it!

Hi Fred, The SP3 has a lot of room inside and is very solidly constructed, so it's a great platform for a DIY add-in like a power supply. You would only have to modify one piece of sheet metal -- the bottom cover -- since that is also the mounting point for the A/B switch in front and jacks in back. Available interior space is approximately 3.3"H x 5.9"W x 7.3"D. Audio jacks are arranged vertically along one edge of the rear panel, leaving several inches of space for additional connectors, possibly even a small fan. Of course you'd have to remove some of the acoustic baffle material, altering the AF response curve in an unpredictable manner. Just thinking out loud, here, but I wouldn't use it as a hiding place for your collection of rare idiophones. 73, Wayne N6KR From phystad at mac.com Sat Sep 12 14:05:59 2015 From: phystad at mac.com (Phil Hystad) Date: Sat, 12 Sep 2015 11:05:59 -0700 Subject: [Elecraft] Elecraft SP3 External Speaker details In-Reply-To: References: <157147629.1485778.1442074311951.JavaMail.yahoo@mail.yahoo.com> Message-ID: <41BF2A6C-343D-4E1B-A19B-946BC10791E4@mac.com> The idea of producing a matching speaker is inevitable given the history of matching speakers (Note: obviously the idea of ?matching? has different interpretations by different vendors). But, 1. When I was nine years old, when my interest in radio started, my dad brought home the radios from his ship (because they were being replaced during a remodel). This was the year 1956. The radio receiver was EH Scott, model SLR: 12-B designed to fit in a rack cabinet. It had a huge (boat anchor quality) matching speaker. 2. My Hammarlund HQ-170AC, circa 1965, had a matching speaker (color and general design features). 3. My Icom 756 (non-pro) had a matching Icom speaker (and, matching power supply). 4. My Icom 756 Pro III had the newer version of the matching Icom speaker (SP-23). 5. And, now, Elecraft has a matching speaker to go along with the K3/K3S. But, unfortunately, I have no plans to buy one because I have no room for its matchability to be useful as my current K-line sits in a nice line up: K3, P3, KPA500 and there is no more room for another side-by-side box. Making room and adding the extra box puts different parts of the K-line too far apart (at least, for me and my operating comfort). So, here I am with my favorite rig, the K3 and maybe the last vendor (Elecraft) that I will ever buy from as long as they keep up their good work, and the first radio (K3) in my personal history without its own matching speaker due merely to the lack of space on my desk top. 73, phil, K7PEH P.S.

If your Pro III is as flawless as mine (& one of the last ones produced) and not used that often (I have 3 radios which reduces wear & tear on any single radio), I would think very long & hard before parting with it. Hopefully you've sat down in front of a K3 and operated it so that your not surprised when you open the box, if you haven't done that...you need to do so. I know some that bought the radio and sold it soon after buying it because it wasn't what they expected. For those that tell you that "you won't regret it", maybe they really do regret parting with their Pro III but just want some company in the dunces corner! I say that you may very definitely regret it!

Nothing offered on their website contains any balancing function.

This is independent of any PWR setting above 1W, and the PA does not engage at higher PWR settings. All this began on Friday afternoon when I switched on the rig. The K3S had been working normally a few weeks ago, but hadn't been used for transmitting in the meantime. An external power meter confirmed that the TX could not deliver more than about 1.5-2W. This was confirmed again by the failure messages from a TX power calibration. While troubleshooting, I progressively uninstalled the KPA3 followed by the KPAIO3A adapter board, but with no change. Even in the simplest 10W configuration with only the small bridge board in place between the two PA connectors, the K3S would still only deliver 1.5-2W with no effective PWR control. I also tried most of the other common tests: unplugged everything else; reloaded an older saved configuration; EEINIT; reloaded the saved configuration again. No change. But I also noticed that the firmware was one release behind the times, so for lack of any other ideas I did a complete firmware upgrade to the latest MCU 5.35 / DSP 2.86 / FPF 1.24 - and it started working again! Normal power output up to 10W, and fully variable up to 100W after reinstalling the PA module. Another TX calibration confirmed that everything was fine. That pleasant surprise seemed to indicate that the problem had been more related to firmware than to hardware. By Friday evening, I believed the problem had gone away... but I should have known better. Today it has failed again, exactly the same way as before. Reloading the same latest firmware didn't work a second time. So now it's the weekend and I'm all out of ideas.

Try re-tightening all of the hardware on the bottom covers, including the screws that hold the PA device tabs to bottom cover B. Also try reseating the 10-W amp module. If this doesn't help, try measuring the 0-dBm drive at the XVTR OUT jack. For this purpose you need to put CONFIG:KXV3B into TEST mode. If you get a full 0 to 1.5 dBm output at XVTR OUT (into a 50-ohm load), but low power output from the 10-W amp module, then the latter is probably implicated. Look at both sides of the module very carefully to see if a component is not soldered at one end, etc. This is rare but it can happen. Also look at the components on the RF board just behind the 10-W amp module. I can give you more detailed signal tracing info if needed.

I've never seen a 7800, so no experience. However, ARRL and Rob Sherwood have. Rob's data is on his webpage. It concentrates on receiver performance. I've gathered ARRL Lab test data for a selected bunch of modern rigs and published it in a form making it easier to compare the rigs as TRANSMITTERS. My report is at http://k9yc.com/TXNoise.pdf The original K3 is MUCH cleaner on CW than the 7800. Also, the original K3 has about 15 dB less phase noise than the 7800, which matters a lot on Field Day and at a multi-TX contest station. The new synth board reduces both TX and RX phase noise quite a bit (I've heard numbers in the range of 10 dB). I haven't seen ARRL Lab tests of the new K3S or a K3 with the new synth board, but I suspect both will turn out to be at the head of the pack for TX cleanliness. Yes, I know about Pure Signal -- NR0V is my neighbor. 73, Jim K9YC From gm3sek at ifwtech.co.uk Sat Sep 12 17:31:33 2015 From: gm3sek at ifwtech.co.uk (Ian White) Date: Sat, 12 Sep 2015 22:31:33 +0100 Subject: [Elecraft] K3S/100 very low TX power In-Reply-To: <69CEC68B-1FF0-432F-B0D8-77CB4391D353@elecraft.com> References: <006901d0ed9d$a27c06f0$e77414d0$@co.uk> <69CEC68B-1FF0-432F-B0D8-77CB4391D353@elecraft.com> Message-ID: <006f01d0eda2$6a4becf0$3ee3c6d0$@co.uk> Thanks for the very prompt response, Wayne!

OTOH, if you will be moving the K3S out, putting the cover on and then pushing it back in place, I would think 1/4 inch additional would be sufficient. 73, Don W3FPR On 9/12/2015 5:03 PM, ae4pb at carolinaheli.com wrote: > Thank you. > Any idea how much space I need between the top of the rig and the bottom > of the hutch to be able to get Rose's dust covers on? > > Thanks..

However, ARRL and Rob Sherwood have. Rob's data is on his webpage. It concentrates on receiver performance.

Also, the original K3 has about 15 dB less phase noise than the 7800, which matters a lot on Field Day and at a multi-TX contest station.

When in more intense operations (DX, contest), when using Split I have the two receivers each in one side of a headset (no speakers - I don?t even own one). For casual rag chewing, stereo not necessary for me and sometimes having a speaker might be better than using a headset. So, the question: Could there be an assigned programmable function which with a single push would switch from stereo headset to mono speaker, thus requiring only one SP3 for these applications? If the answer is yes, I?ll be in line for an SP3.

Hi Fred, The SP3 has a lot of room inside and is very solidly constructed, so it's a great platform for a DIY add-in like a power supply. You would only have to modify one piece of sheet metal -- the bottom cover -- since that is also the mounting point for the A/B switch in front and jacks in back. Available interior space is approximately 3.3"H x 5.9"W x 7.3"D. Audio jacks are arranged vertically along one edge of the rear panel, leaving several inches of space for additional connectors, possibly even a small fan. Of course you'd have to remove some of the acoustic baffle material, altering the AF response curve in an unpredictable manner. Just thinking out loud, here, but I wouldn't use it as a hiding place for your collection of rare idiophones. 73, Wayne N6KR ______________________________________________________________ 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 vk1zzgary at gmail.com From elecraft at mailman.qth.net Sat Sep 12 20:53:45 2015 From: elecraft at mailman.qth.net (George Fritkin via Elecraft) Date: Sat, 12 Sep 2015 17:53:45 -0700 Subject: [Elecraft] K3 to IC-7800 Comparison?

The operator of the K3/0-Mini, although licensed for many year and a very accomplished op, has never used a K3 and, therefore, is unfamiliar with the controls on the K3/0-Mini. The K3/0-Mini was delivered with an Owner's Manual. However, the manual is limited to describing how to set up the Mini to work with a PC, how to operate with the RemoteRig 1258 MKII System (which we are not using), and how to update the Mini's firmware. The K3/0-Mini Owner's Manual does not contain any information about how to use all of the controls on the Mini, or any information about its Menu and Config selections. In the meantime, I have loaned the op my K3 manual, and held training session on the basics of operating a K3. Please let me know if there is a more complete user-oriented K3/0-Mini Operator's Manual, or if will one be forthcoming in the future. Thanks, George.

YMMV. I understand and agree for your use case of mounting the battery internally in the K2. My "fail safe" is to never use an internal battery and thus avoid issues of fire, leakage, etc. I always charge and mount my LiPOs externally. It's certainly possible to abuse LiPOs and cause them to catch on fire, but as you stated, there are plenty of devices that successfully use them internally...significantly more than LiFePO4s when you consider the volumes of cell phones, tablets, PCs, models, drones, etc. that use LiPOs. Just an FYI for anyone interested, the "11.1V 4500mAh 3S 30C Lipo" listed on a popular auction site for $24.36 is actually available for $20 if you use "Make Offer" (I just bought one). Of course you also need a balancing charger (available for around $20) to properly charge and store LiPOs. You cannot beat the energy density (mAH per ounce) of a LiPO but they DO REQUIRE proper care. 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-LiFePO4-replacement-for-internal-SLA-battery-in-K2-tp7607477p7607557.html Sent from the Elecraft mailing list archive at Nabble.com.

I had a Canon camera which had known problems so that I didn't use it much due to "the threat of failure was there every time I turned that radio[camera] ON". So I bought a new camera, a later Canon model, to replace it. Well I turned on the old one to compare the image quality (IQ), and it failed! Sent it to Canon and they fixed it (may have replaced) and I had it back in a week -- at no cost, even though it was out of warranty. Turns out it was a known manufacturing defect -- which the IC-7700 sounds like. End of story is that I preferred the old camera's IQ so returned the new one :-) I wish more manufacturers operated that way. In ham radio, Elecraft is the one I am most confident would (but none of my Elecraft gear has ever failed, even better!). 73, Phil W7OX On 9/13/15 8:01 AM, Chester Alderman wrote: > I certainly agree with Joe about Adam!

I look forward to "hearing them" at maybe one of the next ham fests. I like the fact the SP3 uses an oval speaker. I've never figured out exactly why, but I find ovals typically do sound better than rounds, but maybe it seems to be only in my findings. As a comment, I prefer non-amplified speakers as this avoids the potential RFI issues when used with the radio. The model that I mentioned and use has a slight tilt to the bottom which aligns the front with the K3S with its front elevated by the stand. I also find the audio system in the K3S to be really nice, specially the 2 channel effect using the AFX feature along with a stereo speaker configuration. This give a nice wide spatial effect to which I find very pleasing.

It will protect itself at 60 watts reflected. As explained in the manual, the protection inserts a 3db pad in the RF circuit, effectively dropping the input power in half. If the amplifier continues to see 60 watts reflected it will go into the fault condition. Also, if it sees 100 watts or more of reflected power for a short time, it will immediately go into the fault mode. The only hard SWR limit is 18:1, which is purely a protective scenario for extremely bad loads (short- or open-connections). What all this means is that the protections depend on the transmit power. If you are running 540 watts, an SWR of 2:1 will give you 60 watts reflected, which is the threshold to cause the KPA to start to protect itself. At 240 watts the threshold will be seen at 3:1 SWR, at 135 watts it is 5:1. You can calculate them for yourself with the SWR / power formulas available in the ARRL handbook. So the short answer is that the SWR value for fault depends entirely on how much power you are getting from the amplifier.

I have been waiting for this capability for the P3 since 2010, so as to enable me to monitor transmitter waveforms accurately like I did in my Heath SB-401/SB303 station with the SB610 in ancient times (the late '70's). So now my O'Scope can go back to the bench where it belongs. Since I already had an accurate dual meter peak reading Wattmeter (Autek WM-1), the bundled SWR/Wattmeter capability is not important to me. A good, full featured visual transmitted waveform monitor was what I was looking for. However, a big feature is missing from the TX Monitor option: Accurate monitoring of the direct FSK signal for RTTY. All that is visible on RTTY transmissions is a solid envelope that fills the screen, just like sampling RF using my bench 'scope. True, RTTY is a full carrier FM signal, so the display is showing me the "correct" interpretation for an envelope sampler, but I was hoping to at least see the same display we see on RTTY receive: Two pulses with a valley in between. If both pulses are equal, there is no passband ripple. If there are single peaks and the fall to the valley is smooth and sinusoidal, all is well and the transmitter is not being overdriven. My preference, however, would be to see a traditional crossed ellipsis display like on my old SB610 and the simulated one on software RTTY apps (that are NOT real transmitted waveforms!), but I can live with the above. Neither mode is available on the simple envelope sampler add on that comprises the TX Monitor today. I don't use AM here, but the a "Trapezoid" display would also be helpful to set amplifier linearity and peak modulation. These features would make a P3 with the TX Mon option a real, full featured, transmission monitor, which was my assumption that it was to be.

Any request for features intended help the operator adjust his equipment for a cleaner transmitted signal is valid in my opinion. In fact, I tip my hat to you: one doesn't have to listen around very much to hear "crud" on the bands coming from ops who either don't know and/or don't care about how to adjust things properly, so by contrast it's refreshing to find someone who is concerned about his signal quality.

Since FSK is a constant-amplitude modulation mode, all you see is a constant-amplitude envelope on the screen. It gets more interesting if there is a problem in the RTTY transmitter that causes the two tones to come out at different amplitudes, which would be easy to see on the screen. The traditional "plus sign" (crossed ellipses) display is normally used in the FSK receiving demodulator as a tuning aid. As you tune the receiver the ellipses change their angle. When you see the "plus sign" then the receiver is tuned correctly. You can also see if the transmitter has the wrong (or at least different) frequency shift. In that case the ellipses don't make a right angle with each other even when the receiver is tuned correctly. That might be useful in a transmit monitor, but it can't be done using an RF coupler because it only detects the amplitude, not the frequency. A "trapezoid" display would be interesting, but it requires two RF coupler/detectors, one at the input of the amplifier and one at the output. Any non-linearity in the transmitter shows up as a non-linearity in the trapezoid. An alternative that serves the same purpose is a "triangle" display, in which the RF signal ramps up and down from zero to PEP and back. You feed the mic input of the SSB transmitter with a (say) 1500-Hz sine wave that is modulated with a (say) 100 Hz triangle. The P3 TX monitor would then show any non-linearity in a manner similar to a trapezoid. Alan N1AL On 09/13/2015 01:29 PM, Luis V.

My shack is 20' from the kitchen and not having radio noise is appreciated by the people cooking, so most of the time I use the radio with headphones. Having a mechanical function to switch the speaker on/off I avoid using a PF control. (2) The MH2 acts as a push-to-talk switch for the CM300 microphone.

Also note that the receiver equalizer is not used in the 50 Hz and 100 Hz widths, so if the radio is set up for a boost at the selected pitch frequency, the amplitude will drop. Be sure the receiver equalizer is set to o in the frequencies that include the desired pitch.

On the other hand, a CW signal centered in the passband doesn't change much if at all. I'm pretty sure that's how it's supposed to work. I can detect a tiny decrease in the signal level but it is just discernable, nothing big or a problem. I normally run CW in contests at 250 Hz, sometimes 200 Hz, I have used 100 Hz occasionally when necessary. I don't think I've ever used 50 Hz, CW sidebands at 30 WPM exceed that and the code elements start to run together from ISI. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 9/13/2015 7:41 PM, Keith Onishi wrote: > One of my friend K3 users report that AF output level with 100Hz > passband width is lower than with 150Hz passband width.

The CONFIG is set to transmit CW using the 2.7kHz filter, but the power output seems to vary on the main RX when I narrow the receive bandwidth down to 400Hz where FL4 kicks in. I first discovered this yesterday when trying to set up SSB. After following all the setting instructions I didn't get much RF out when I went to normal TX and full power. I didn't try this with the opposite sideband, but I now suspect that one sideband will be good and the other will be poor. When I get back tonight I will check the filter responses using band noise and a program called Visual Analyser from Sillanum Software which allows me to plot both the main and sub-RX frequency responses at the same time.

To quote: "There's an important caveat to his work. The NPR measurements require very sophisticated band-stop filters in his instrumentation setup, and based on the filters he has been able to source, that limits the frequency range where he can do his measurements. An example is in the footnote for the Flex-6700, which has no preselector for the range where he had to do his measurements, which may have caused that radio to measure worse than it would on the ham bands." The instrumentation I use for NPR testing is re-purposed telecom test equipment, as described in my Web article and also in my article in QEX for March/April 2015. I rely on the surplus market for the test sets, and also for the filter pairs (bandstop and bandpass). The bandstop filters typically have 95 dB stopband attenuation and ~ 3 kHz stopband width. A number of these filters are on (or near) amateur bands, e.g. 1940, 3886, 5340, 7600 and 11700 kHz. The first filter pair I acquired was on 5340 kHz, so all the test data in my web article are on this frequency (which is in the 60m band). The Flex-6700 does not have a preselector for this band, so the noise loading will hit the front end and the ADC harder. This will degrade the NPR reading by a few dB, but it will show how the receiver behaves if heavily loaded on a band for which no preselector is fitted. As I picked up additional filters, the number of frequencies on which I run the test has steadily increased.

You do not want to use +db boost for CW. As I understand it, RXEQ is disabled at 100Hz and 50Hz width. So if he has boosted a particular frequency by 10db then when he narrows the bandwidth he will suddenly hear a loss of audio signal of 10db. To solve this problem keep the RXEQ set to 0 db for the frequencies of interest and use negative db settings for the frequencies of no interest. 73, Mike K2MK Keith Onishi wrote > One of my friend K3 users report that AF output level with 100Hz passband > width is lower than with 150Hz passband width.

I think it would be the ideal size for the interface. Using 2 K3/K3S radios and full amplifier capability. This would include sequencer switching for turning off amplified RX arrays and a 12/13.6 V power supply switching for an array pre-amp. Power supply does not need to be included, just a good fast relay to sequentially turn off the pre-amps so they don't get blown up using an amp in near proximity. Include an input for a ps on the back and that way what ever pre-amp you have the op supplies the voltage and you supply the switching. Next using the same size box, the KAT500, put band pass filters in the box for 2 radios or at least one radio. Auto and manual buttons on the front panel if possible. Most importantly, the matching SO2R box and i can deal with filters as needed for the antennas that I use. I don't even have a K3S yet but soon will be making a $6000 investment of a K3S and associated equipment. Lastly, If possible making a 1000 to 1200 or possible 1500 watt amp in 2 boxes each the size of a K3S?10x10x4. Use one box for the PS and the other for the amp. PS on the floor to clean up op table and keep the flow of the gear. I loved the Ten Tec titan amp and omniV gear that I once owned because it all fit together well. I currently have the 1.5kl THP amp. What a great amp that is. Way over built but rock solid stable. It puts out 900 watts and it is solidly built but weights a ton. If the same guts but in 2 boxes PS/RF control decks, that would make my day. Yes i know it is going to be costly but what good amp is not costly. And yes i understand the cost benefit ratio that a small business must analyze but I also think that Elecraft people drink the koolaide and would gladly love to have a black ugly box that says elecraft on it in the spartan, utilitarian fashion that is so epicly descriptive of the Elecraft line. No frills that not needed, just pure function done well. I just pulled 800 feet of coax and switching cables today and will soon be putting down 1200ft of radials under a vertical. Next year is the tower. Beams are in the garage. Plan to be radioactive in october and doing SS in Nov as my first contest in 16 years. 73 NJ8M From kl7gg at gci.net Mon Sep 14 10:55:23 2015 From: kl7gg at gci.net (Charlie Horsman) Date: Mon, 14 Sep 2015 16:55:23 +0200 Subject: [Elecraft] Fw: important Message-ID: <74eb842b0c0fe2ad.e6a41595@gci.net> Hello!

On the other hand Adam limits noise power for direct sampling SDR designs to a lower level than used with traditional up/down conversion transceivers. The lower noise power input gives the direct sampling designs an unfair advantage be ignoring strong signal environments. 73, ... Joe, W4TV I certainly agree with Joe about Adam! I've never heard such prejudicial explanations trying to justify Icom's innocence for final transistor failures in the IC-7700's. He took all reports of final failures and said he was going to forward them to Icom, but very few of us ever believed he actually forwarded any information to Icom from IC-7700 users about the failures. And IF did, there was never any response from Japan. I sold my IC-7700, not because the finals failed, but because the threat of failure was there every time I turned that radio ON. 73, Tom - W4BQF From ae4pb at carolinaheli.com Mon Sep 14 11:33:03 2015 From: ae4pb at carolinaheli.com (ae4pb at carolinaheli.com) Date: Mon, 14 Sep 2015 11:33:03 -0400 Subject: [Elecraft] Elecraft SP3 External Speaker details In-Reply-To: <55F5CE5B.6040009@blomand.net> References: <2125099722.1591958.1442102529869.JavaMail.yahoo@mail.yahoo.com> <55F4C00D.40008@blomand.net> <6E11CA6E-14D0-478C-ADB2-3B1B22C433D3@gmail.com> <55F5CE5B.6040009@blomand.net> Message-ID: <05f201d0ef02$a684d2c0$f38e7840$@carolinaheli.com> I believe when you consider the engineering reputation of Elecraft and economies of scale for the manufacture of the SP3 several expectations arise: 1.

Message-ID: <003501d0ef10$4a3a3bf0$deaeb3d0$@ca> For Joe, W4TV: To quote: "On the other hand Adam limits noise power for direct sampling SDR designs to a lower level than used with traditional up/down conversion transceivers. The lower noise power input gives the direct sampling designs an unfair advantage be ignoring strong signal environments." As explained in my web article (and also in my QEX article), the optimum noise loading points for an ADC and a conventional receiver are different. In the conventional receiver, optimum noise loading is reached when the noise power induced in the IF passband within the notch (idle-channel noise) is equal to the DUT's intrinsic thermal noise power in the same bandwidth. At this point, the DUT's audio output rises by 3 dB. Walt Kester of ADI states in ADI Tutorial MT-005 that the optimum noise loading point for an ADC is where the device's quantisation noise equals the noise generated by clipping, i.e. the noise loading is run right up to clip level or 0 dBFS. I use -1 dBFS as my optimum noise loading point, to ensure that no clipping takes place during the test. In fact, when an ADC is driven to clip level, it crashes, thus invalidating any tests attempted above clip level. I do not compare NPR test data for direct-sampling receivers directly with data for conventional receivers. The benchmark I use for direct-sampling receivers is the theoretical value of NPR for the ADC in use; this can be calculated using the procedure presented in MT-005 and described in my articles. The closer the measured NPR value is to the theoretical one, the better the front end will perform under heavy loading. A large drop in NPR (10 dB or more) as compared to the theoretical value indicates an anomaly such as passive IMD in the preselector or IMD in an active stage ahead of the ADC. For a conventional receiver, the closer the NPR figure is to the bandstop filter's stopband attenuation, the better the receiver (at least from the NPR standpoint). I do not use NPR as the sole criterion for receiver selection; my intent in adapting this test method to HF receivers is to provide the test engineer with an additional test tool for evaluating a receiver's behaviour on a band packed with extremely strong signals. Along these same lines, it is virtually impossible to correlate certain narrow-band test results for a direct-sampling receiver with those for a conventional receiver, as the familiar traditional test metrics (DR3, IP3, blocking gain compression) are completely meaningless in the context of an ADC. Phase noise (RMDR) is still very much a valid parameter, but RMDR in a direct-sampling receiver is usually very high as the ADC clock is the only major source of phase noise. (ADC aperture jitter is a minor phase noise source.) Of course MDS is valid for both receiver types. I have proposed, and myself use a front-end IMD test method in which I measure the absolute power of the IMD3 products at 2 kHz spacing over a range of input power levels, and draw a chart. I then draw lines across the chart at the typical ITU-R urban and rural band noise levels. If the IMD product is below the site band noise level, it is inaudible and can thus be disregarded. I term this test IFSS (interference-free signal strength) and use it exclusively in my direct-sampling SDR test suite. Ultimately, the decision as to whether to acquire a direct-sampling SDR or a conventional transceiver comes down to the operator's personal operating preferences. 73, Adam VA7OJ/AB4OJ From elecraft at mailman.qth.net Mon Sep 14 13:12:05 2015 From: elecraft at mailman.qth.net (Dan Atchison via Elecraft) Date: Mon, 14 Sep 2015 13:12:05 -0400 Subject: [Elecraft] K3/K3S Pin 1 question Message-ID: <55F6FFE5.1060807@aol.com> I am building a switchbox to allow use of a Heil PR-781 microphone to be used by my K3S and K3, the switchbox using XLR connectors.

I now have a calibrated KX3. But I'm uncertain if it is sufficient. Nor do I know exactly what has caused the problem. It suspect the problem arose because of the cable or connector from the dummy load to the KX3 was not-quite-right. If you have any other theories I would appreciate hearing them. Here is what I did. In the original transmit calibration I used an MFJ Model J 280-C dummy load . As suggested, I tested the MFJ dummy load at 52 MHz with an MFJ-269 SWR Analyser. It had an SWR of 1.1 (with R=53 X=3) at 52.0 MHz. While executing the KX3 "Manual Transmit Gain Calibration" the SWR shown at the same frequency was 1.6 at 4.0W. The calibration produced the same error as before. But note that the value of "d" is always a different number. I checked the SWR of the Elecraft DL1 that I built when assembling my K2. It tested at an SWR of 1.1 (with R=54 and X=4.) Running the manual TX calibration the SWR on the KX3 was 1.4. The calibration failed with the same error message as with the MFJ dummy load. Both of the calibrations above were done with an antenna cable purchased from Elecraft. So, I repeated the TX Calibration on the KX3 using a different cable from my spares box. The SWR with both dummy loads was the same but the test passed with the DL1 and not the MFJ. Then I repeated the calibration with other cables. About half of these calibrations done with the the MFJ and the DL1 failed with both dummy loads. However, using two other cables the calibrations with the DL-1 passed but not with the MFJ. Then, with two more cables the MFJ calibration passed and the DL-1 calibration failed. Note that the MFJ has a PK-259 connector and the DL-1 has a BNC connector. Since the cables I used for the calibrations vary as to which connector combination they have I was forced to use adaptors. I suspect the adaptors may not quite be up to snuff. So the calibration succeeds with some combination of cable and DL1 dummy load or MFJ dummy load.

This is likely a very well-engineered component that's not easily replaced by a similar sized speaker. 2. Performance of the speaker exceeds similarly priced speakers (and definitely less expensive ones to a degree). 3. There is NOT likely a premium baked in to the price for the Elecraft name due to the economies of scale (low quantity manufacture generally means higher costs, thus higher price). Translation - the price isn't just for the name. At the end of the day consider the labor costs plus parts are likely fairly high if they are US manufactured. The US consumer is the sole reason most US manufacturing has gone overseas (especially China). Buy cheap, get cheap. So it comes down to a question of quality vs "good enough" vs "price" I can only speak for myself in saying that it means something to have a matching set rather than a hodgepodge. I do compromise and use what I have to be able to get the job done UNTIL I've saved enough for the next piece.

I look forward to "hearing them" at maybe one of the next ham fests. I like the fact the SP3 uses an oval speaker. I've never figured out exactly why, but I find ovals typically do sound better than rounds, but maybe it seems to be only in my findings. As a comment, I prefer non-amplified speakers as this avoids the potential RFI issues when used with the radio. The model that I mentioned and use has a slight tilt to the bottom which aligns the front with the K3S with its front elevated by the stand. I also find the audio system in the K3S to be really nice, specially the 2 channel effect using the AFX feature along with a stereo speaker configuration. This give a nice wide spatial effect to which I find very pleasing.

In your example, you would see ripple in the flat waveform on the screen, true enough. The Ripple would increase with the amount of the different amplitudes of the two tones. However, I can't monitor other issues that can rear their ugly heads in RTTY, be it modulated by FSK or AFSK with the existing functionality available: The reason I was looking for a better visual representation of these issues in this tool is explained in an excellent article by Andy Flowers, K0SM. http://frontiernet.net/~aflowers/k3rtty/k3rtty.html Gee, it would be nice not to have to buy a Flex rig just to monitor my K3's output. And I already have an SDR receiver sitting inside the P3 box, locked to my transmitter frequency. You wrote: The traditional "plus sign" (crossed ellipses) display is normally used in the FSK receiving demodulator as a tuning aid. As you tune the receiver the ellipses change their angle. When you see the "plus sign" then the receiver is tuned correctly. Not just for receive, but in transmit as well. Especially in tone modulated RTTY (pseudo FSK) using AFSK "tone" modulation. If one tone is off, it would be shown in the transmission ellipsoid representation as well. When you see a "plus sign", both tones are in phase and in quadrature. But if one tone is out of quadrature? Then you see an ellipse. We deal with this daily in the representation of Trellis modulation artifacts in ATV transmitters. There we call it "The Eye Pattern". Same display principle. While the dual ellipse waveform would be ideal, there are alternatives, In receive, we can see similar information in the two tone demodulation "envelope" showing two peaks with a valley in between using a single envelope detector as described bu K0SM. Why not avail us of at least that waveform, since you already can show it on receive in the P3 hardware/software? With some handles on the display for gain, width, slope and maybe a synthetic "mask", it solves this requirement! You wrote: You can also see if the transmitter has the wrong (or at least different) frequency shift. In that case the ellipses don't make a right angle with each other even when the receiver is tuned correctly. True and correct. And I agree. You wrote: That might be useful in a transmit monitor, but it can't be done using An RF coupler because it only detects the amplitude, not the frequency. True: Not the *quadrature* (two ellipsoids) display. But you *can* show the dual peak/valley display. You already show it on receive! It is an equivalent 2-D representation that can be used in addition to the flat envelope display. But, alas, I can't see it in transmit (yes, I could unplug the control cable to see IF "bleedthrough", but what a pain!). The way it is now, I can only tell folks I am receiving that they are having problems. I can't proactively solve my own problems before I transmit with my monitoring tool! I don't know. Maybe I'm just old fashioned, but I'm really disappointed to have waited 5 years and paid $200 for this simple envelope sampler functionality using a repurposed WM2 sampling bridge. I sort of expected more. Maybe not in hardware, but in the application software, as all hardware for this type of measurement is synthesized in apps anymore. For $200 more I could have gotten a Wavenode WN-2, but then I have wasted the wattmeter again and I would need another PC to run the app software. But the funniest thing is that the P3 can display an equivalent waveform today in receive that does what I need for transmission monitoring! I'm still no better off and $200 poorer than where I was with my Bench Oscilloscope and a 17 inch piece of hook up wire, and that is the issue. It's the first time I have been disappointed by an Elecraft product.

Mine is a little different, as I have a 27? iMac - sitting off to the left. But here?s what my setup is like: - A 54? wide, 24? deep double pedestal desk with a solid core 80? wide x 32? deep door sitting on top. This gives me a w-i-d-e operating surface. - The iMac sits off to the left. On top I build a double high ?riser? out of 3/4? oak plywood, faced with oak strips.; the bottom riser is 4-1/2? high x 48? wide. Under it are my two Begali keys - a paddle and a straight key. Also gives me room to slide my wireless keyboard and track pad underneath when not in use. The upper riser is 5-1/2? high x 20? wide and sits on the left end of the lower riser, basically directly in front of me. Sitting on the second level (the top of the long riser) are, from left to right: K3, P3, KPA500, homebrew 144 MHz 80 watt amp, and an MFJ-4245MV power supply. My KAT500 tuner sits atop the KPA500. This arrangement puts the K3/P3 directly in front of me, and allows me to move the keys around on the desk under them as I want. On top of that third level, the upper riser, I have sitting an ASUS 23? second monitor, a KX3, and my Tascam external sound card. The upper surface of each riser is covered by black, non-stick, rubberized, ?shelf paper? I got at a fabric store. Keeps stuff from sliding around. I like having the K3/P3 directly in front of me and the keys under them. I previously had this equipment in place without any risers and was not 100% happy with the layout or the ability to use the equipment easily.

In 2010 I used the club 7700. The receiver sounded really crunchy, much like my former TS850. Lots or crackly splatter, lots of adjacent desense. I use that rig often, so I know how to drive it. It is never pleasant to use that rig in heavy QRM contest conditions. The same can be said for the 7600'ds. The 746 and the 7100 are worse by a long shot to the 7700. The following year, I brought my K3 to the club and operated SS using the club's identical antenna complement. Not once did I hear any crunching in the receiver, no splatter mess and no desense. The contest was much more pleasant on the ears and all signals were much easier to copy on the K3 than on the 7700 receiver. I love using the 7700, but not in a serious contesting environment. It reminds me of my old TS850. But I still love to use it! The reason is the tactile feel of the 7700 and, a bit less by the same token, the 7600'ds feels like that too. While the K3 layout is fine and very workable, the controls on the Icoms are just so incredibly smooth! The "feeling of Luxury" is exuded by the 7700'ds tactile feedback from its controls. As a NY friend says "It feels like buttah!". It's a hard concept to explain, but the feel of the Icom controls is really special. My K3 feels OK, just not as "silky" as the 7700'd. Kind of like cars. Drive a Lexus SC430 for show, and a Lotus Elise for go. Two sports cars for different priorities. If you are into luxury feel, "free" logo'd leather jackets, and 70lb transceivers that "feel like buttah", the 78/7700'ds are a great choice. If you are into well behaved receivers, high operational performance in a compact, under 10lb lightweight package, the choice is obvious. Takes all kinds to make a world! I have my priorities, you have yours.

You will not need any more than 3/4 stock for the shelf and top of the hutch. If think you need extra support for the shelf, glue a 2 inch wide strip to the back edge of the shelf and top (under the shelf). That way you have maximum view in the front of the hutch. That will also keep the hutch from racking if you fit the ends tight. Since your hutch will not be close to the end of the desk, just build it and place it loose on the desk. That way you can move it from side to side to see what position is going to work best for you. Once you determine that position you can fasten it to the desktop if desired. 73, Don W3FPR On 9/14/2015 3:28 PM, ae4pb at carolinaheli.com wrote: > It's been a while and I'm a huge proponent of measure twice cut once.

That means 3 poles to switch from the XLR input to the 8 pin Foster connectors. Keep all away from chassis ground. If you believe the box should be grounded, I suggest doing so at the input XLR pin #1 to chassis ground. And keep ground between the outputs, being the Foster connectors, separate so as not to connect the two radios together through the shield/ground. 73 Bob, K4TAX K3S s/n 10,163 On 9/14/2015 12:12 PM, Dan Atchison via Elecraft wrote: > I am building a switchbox to allow use of a Heil PR-781 microphone to > be used by my K3S and K3, the switchbox using XLR connectors.

I mostly use fldigi for digital modes so I use the rig control functionality it offers. Again as mentioned by another lit member, the fldigi folks do have a separate rig control program called flrig.

The answer is that it depends on the kind of cable used -- single conductor plus shield with mic low on the shield, or twisted pair plus shield, with the mic low not connected to the shield. If twisted pair plus shield, carry mic high and mic low to their designated pins on rig, and connect the cable shield to the shielding enclosure (the chassis, in a K3 or K3S). For any shielded twisted pair going to an unbalanced input, the connection between one side of the audio and the chassis should be at the radio input. This allows audio to stay on the twisted pair, which inherently rejects noise by virtue of its twisting. If a single conductor plus shield, connect mic high in the cable to mic high in the radio, and the cable shield to the chassis. In your plan, you would want to switch everything but the shields. NEVER connect a cable shield to a return pin unless that pin has a direct short to the chassis at the connector. To do so is, by definition, a Pin One Problem, and a major cause of hum, buzz, and RFI. 73, Jim K9YC From jim at audiosystemsgroup.com Mon Sep 14 17:52:18 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 14 Sep 2015 14:52:18 -0700 Subject: [Elecraft] K3/K3S Pin 1 question In-Reply-To: <55F702FE.3040003@embarqmail.com> References: <55F6FFE5.1060807@aol.com> <55F702FE.3040003@embarqmail.com> Message-ID: <55F74192.6000006@audiosystemsgroup.com> On Mon,9/14/2015 10:25 AM, Don Wilhelm wrote: > I would preserve the balanced configuration through your switchbox and > only connect the mic low to ground at each radio's plug.

At the transceiver the shield should be connected to the *shell* of the Foster plug which should, in turn, be bonded to the *case/chassis* of the transceiver. Connecting a shield via a connector pin to a circuit board then via a "long" trace back to the chassis/case (power supply return), is the very definition of the "pin 1 problem." Every amateur transceiver has a pin 1 problem and most third party accessories have to deal with that issue in their own (typically non-standard) way. 73, ...

I strongly disagree, Adam. If the test is designed to show response of the receiver to a lot of strong signals such as are present in a contesting or DX pileup environment, or as are present in a multi-transmitter site, the signal level should be consistent with that environment, NOT with the design of the receiver. In other words, if the input of the RX would be overloaded by those strong signals, the test should show it. This does (at least) two things -- it lets buyers know which radios perform best in this environment, and it also puts the manufacturer's feet to the fire to make the RX better. And this matters no matter what the architecture of the RX. It would also, for example, clearly show the difference between an RX with a preselector (or other selectivity) in front of the input and one without. And finally, if you choose to test at a reduced signal level to stay below overload, the report should clearly state by how many dB the test signal had to be reduced. I do appreciate your work and your dedication, but to be of value, it must be consistent with real world conditions, and it must expose the real differences between radios. 73, Jim K9YC From lists at subich.com Mon Sep 14 18:14:32 2015 From: lists at subich.com (Joe Subich, W4TV) Date: Mon, 14 Sep 2015 18:14:32 -0400 Subject: [Elecraft] P3 TX Mon: FEATURE REQUEST - Monitoring of RTTY Waveform In-Reply-To: <001601d0ef1e$e360be90$aa223bb0$@ij.net> References: <001601d0ef1e$e360be90$aa223bb0$@ij.net> Message-ID: <55F746C8.30301@subich.com> On 9/14/2015 2:55 PM, Luis V.

TX MON is strictly a time domain (amplitude) display. TX Mon uses a amplitude detector driven by a directional coupler. To do what you desire would require an SDR tuned by frequency data (TX frequency) from the K3. The difference between an envelope (diode) detector and a tracking SDR is a couple of orders of magnitude in both cost and complexity. 73, ... Joe, W4TV On 9/14/2015 2:55 PM, Luis V.

Message-ID: <003801d0ef47$c8495530$58dbff90$@ca> Hi Jim, To quote: "If the test is designed to show response of the receiver to a lot of strong signals such as are present in a contesting or DX pileup environment, or as are present in a multi-transmitter site, the signal level should be consistent with that environment, NOT with the design of the receiver." My explanation of the optimum noise loading point was intended to clarify the test procedure. As it happens, the optimum noise loading point for an ADC is also the clipping point, which is the limiting case for a direct-sampling receiver with an ADC at RF. I state clearly in my test reports for direct-sampling SDR's that I am testing NPR just below the clip point. This hard limit dictates the maximum aggregate signal power at which the receiver can still be expected to demodulate signals correctly (assuming no attenuation is inserted ahead of the ADC). I cannot perform the test above ADC clipping, as it will then yield no usable results. In practice, some attenuation can often be inserted to extend the upper power limit of the ADC, especially on the lower HF bands where the band noise level is usually several dB above the receiver's noise floor. I have applied noise loading levels as high as -1 to 0 dBm when testing some direct-sampling SDR receivers. This is equivalent to approx. 1000 contiguous SSB voice channels, all transmitting simultaneously at S9 + 40 dB each. In the final analysis, it is up to the radio buyer to decide whether or not a direct-sampling SDR can handle his chosen operating environment. 73, Adam VA7OJ/AB4OJ From eric at elecraft.com Mon Sep 14 20:31:48 2015 From: eric at elecraft.com (Eric Swartz - WA6HHQ, Elecraft) Date: Mon, 14 Sep 2015 17:31:48 -0700 Subject: [Elecraft] Elecraft SP3 External Speaker details In-Reply-To: <1255158815.1600701.1442246572020.JavaMail.yahoo@mail.yahoo.com> References: <05f201d0ef02$a684d2c0$f38e7840$@carolinaheli.com> <1255158815.1600701.1442246572020.JavaMail.yahoo@mail.yahoo.com> Message-ID: <55F766F4.3080604@elecraft.com> Yes, the SP3 is made in California, as are all of our radios. 73, Eric /elecraft.com/ On 9/14/2015 9:02 AM, ac5p at sbcglobal.net wrote: > Jerry's (AE4PB) post and others suggest new speaker is actually made in the USA.

The market will decide how well the SP3 is accepted just as the market will decide on any alternative offerings from other manufacturers. Some if not many of us will choose the SP3, over any alternative, others will make their own choice. It's a free world (up to a point) I choose Elecraft. I borrowed 2cents to throw in here. Our dollar has sunk so low I need a submarine to find it.

Building and operating my K2 and K1 (I have the 4 band kit of the latter and feel lucky) are among the biggest ham radio thrills I've had. You don't get to start on a new kit very often, and it was exciting today to start the old routine (all I did tonight was conduct a complete parts inventory) that I employed with the other kits. I'm looking forward to leisurely working through the kit (it's a K3s/100 with the ATU) while listening to music in the background. Of course, I'm looking forward to firing it up on the air one day. Just thought I'd share this feeling with all of you, many of whom, I'm sure, have felt the same way. By the way, I don't care much about what serial number I get. It does make the rig unique, and places my particular rigs where they belong on the Elecraft spectrum (my K1 is # 1024 and my K2 is #6922). Since I ordered my K3s (#10323) on September 7th, this tells any of you about to order one what your serial number is likely going to be. 73 de Bernie, KF0QS -- View this message in context: http://elecraft.365791.n2.nabble.com/K3s-10323-tp7607669.html Sent from the Elecraft mailing list archive at Nabble.com.

I still hate the tap/hold interface. I paid what I feel was an obscene amount of money for a set of heavy, machined VFO knobs to replace the stock ones. I wish the K3 had more room for controls, so there would be less overloading of functions. But all this pales into insignificance when I dial down the selectivity and pick out the weak one in the midst of the pounding 20-over signals from nearby EU stations. And then there is the improvement in copy from diversity reception! Everyone has different interests. Mine is to work DX on CW. Satisfaction doesn't come from a comfortable interface, but rather from achieving one's goals. The K3 is simply the best tool available to do that.

Tuner situation - I run a Yaesu FT 950 and don't use the onboard tuner because I get much better results with an MFJ 969 manual tuner, which will almost tune lawn furniture. I use the ATU in the KX3 (which apparently *will* tune lawn furniture) because it gets better results than the MFJ 969.

Hi Johnny, The K3 with the KSYN3A is in a closely-packed cluster of radios which score highest in the NPR test. Its exact ranking depends on which test frequency is being compared. The differences are very slight, mostly within a couple of dB. In practice, I regard an NPR value of 80 dB or higher as excellent. 73, Adam VA7OJ/AB4OJ From: Johnny Siu [mailto:vr2xmc at yahoo.com.hk] Sent: 14-Sep-15 00:54 To: Adam Farson; Elecraft List Subject: K3 to IC-7800 Comparison?

Adam Farson ???? Elecraft List ????? 2015?09?14? (??) 2:51 PM ??? Re: [Elecraft] K3 to IC-7800 Comparison? For Jim K9YC: Hi Jim, Many thanks for the post on my presentations at the club meeting on Saturday September 5. To quote: "There's an important caveat to his work. The NPR measurements require very sophisticated band-stop filters in his instrumentation setup, and based on the filters he has been able to source, that limits the frequency range where he can do his measurements. An example is in the footnote for the Flex-6700, which has no preselector for the range where he had to do his measurements, which may have caused that radio to measure worse than it would on the ham bands." The instrumentation I use for NPR testing is re-purposed telecom test equipment, as described in my Web article and also in my article in QEX for March/April 2015. I rely on the surplus market for the test sets, and also for the filter pairs (bandstop and bandpass). The bandstop filters typically have 95 dB stopband attenuation and ~ 3 kHz stopband width. A number of these filters are on (or near) amateur bands, e.g. 1940, 3886, 5340, 7600 and 11700 kHz. The first filter pair I acquired was on 5340 kHz, so all the test data in my web article are on this frequency (which is in the 60m band). The Flex-6700 does not have a preselector for this band, so the noise loading will hit the front end and the ADC harder. This will degrade the NPR reading by a few dB, but it will show how the receiver behaves if heavily loaded on a band for which no preselector is fitted. As I picked up additional filters, the number of frequencies on which I run the test has steadily increased. Links to multi-frequency NPR data for various radios (including the K3 with KSYN3A) are on my website: http://www.ab4oj.com/test/main.html#NPR It was a pleasure meeting you guys over the Labour Day weekend. 73, Adam VA7OJ/AB4OJ ______________________________________________________________ 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 jbollit at outlook.com From ae4pb at carolinaheli.com Tue Sep 15 08:14:08 2015 From: ae4pb at carolinaheli.com (ae4pb at carolinaheli.com) Date: Tue, 15 Sep 2015 08:14:08 -0400 Subject: [Elecraft] K3: reverse 12 volt supply In-Reply-To: References: <009401d0ee98$d6f7fb40$84e7f1c0$@yahoo.com> <55F63A77.7090207@embarqmail.com> <000301d0ef3a$a78b4bd0$f6a1e370$@earthlink.net> Message-ID: <073001d0efb0$06b98b10$142ca130$@carolinaheli.com> I have an idea.

I'm just hoping to go UP if needed or maybe adding small toggles under the shelf that extend antenna rotator controls if I get that far. At this point I'm debating a 4 square setup for 160/80/(?40) homebrew until I'm at the point to do something better. That gives me some experimentation projects to work on. 160/80/40 due to the sunspots being low. Those bands should be optimal I'd think.

Message-ID: Adam, You are digging a deeper hole........... JimW6AIM . -------- Original message -------- From: Adam Farson Date: 9/14/2015 6:48 PM (GMT-06:00) To: jim at audiosystemsgroup.com Cc: Elecraft List Subject: [Elecraft] K3 to IC-7800 Comparison? Hi Jim, To quote: "If the test is designed to show response of the receiver to a lot of strong signals such as are present in a contesting or DX pileup environment, or as are present in a multi-transmitter site, the signal level should be consistent with that environment, NOT with the design of the receiver." My explanation of the optimum noise loading point was intended to clarify the test procedure. As it happens, the optimum noise loading point for an ADC is also the clipping point, which is the limiting case for a direct-sampling receiver with an ADC at RF. I state clearly in my test reports for direct-sampling SDR's that I am testing NPR just below the clip point. This hard limit dictates the maximum aggregate signal power at which the receiver can still be expected to demodulate signals correctly (assuming no attenuation is inserted ahead of the ADC). I cannot perform the test above ADC clipping, as it will then yield no usable results. In practice, some attenuation can often be inserted to extend the upper power limit of the ADC, especially on the lower HF bands where the band noise level is usually several dB above the receiver's noise floor. I have applied noise loading levels as high as -1 to 0 dBm when testing some direct-sampling SDR receivers. This is equivalent to approx. 1000 contiguous SSB voice channels, all transmitting simultaneously at S9 + 40 dB each. In the final analysis, it is up to the radio buyer to decide whether or not a direct-sampling SDR can handle his chosen operating environment. 73, Adam VA7OJ/AB4OJ ______________________________________________________________ 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 jbollit at outlook.com From rmcgraw at blomand.net Tue Sep 15 09:11:17 2015 From: rmcgraw at blomand.net (Bob McGraw - K4TAX) Date: Tue, 15 Sep 2015 08:11:17 -0500 Subject: [Elecraft] K3 / K3S Station setup question In-Reply-To: <1442320739.8107.5.camel@nostromo.nk7z> References: <066001d0ef23$9b3d8b20$d1b8a160$@carolinaheli.com> <1442260503.8107.0.camel@nostromo.nk7z> <06ef01d0ef53$ab603f40$0220bdc0$@carolinaheli.com> <1442320739.8107.5.camel@nostromo.nk7z> Message-ID: <55F818F5.7010109@blomand.net> I build furniture as one of my hobbies. Therefore I could build a custom, made to fit, each piece of equipment enclosure or desk. However, my station is in a reconfigured built in book case system. Cabinets are located below with doors, and above, shelves are extended to depths of 12" to 18" for equipment and operation, extend to the ceiling. Plus it is some 6 ft wide. A series of holes in each shelf allows running cables left to right and up and down. Over some 20 years it has contained and supported various pieces of equipment from a fully configured Collins S Line plus a 5 transceiver accumulation and now down to two transceivers and one amplifier and tuner. Being on the 2nd floor of the house, all feed lines and rotor control traverse the attic and drop down through the ceiling to the tuner and coax switch arrangement at the operating position. The point being.........flexibility is a must with any installation and configuration. 73 Bob, K4TAX K3S s/n 10,163 On 9/15/2015 7:38 AM, David Cole wrote: > Hi, > Just making the point that as things are added, you will need more > space...

Sure, a offshore company might be able to make a close copy and sell for less, but that is likely due to the abysmal compensation paid to many workers there. If you were to build an SP3 yourself, it?s not merely the cost of components and materials, but also the cost of tools (fine, if you have them already) and the time it takes to build and test it. Yes, it might be ?fun? to build it, but the fact is you are paying for your labor? in time that is taken from some other enterprise. Time is money, too. And, you would have to include the time it takes to plan (engineer), gather materials, and the place where you will build it. All of those tend to be invisible costs, but they are costs. I?m sure many people would prefer to take advantage of the economies of scale, and let Elecraft make the speaker for them. Of course, everyone lives on some sort of budget, and the price of the SP3 puts it out of reach for some people. As mentioned, I think the market will decide. 73 de Ray K2ULR KX3 #211? and no need for the SP3.

Right? As in breaking a law or violating a bible verse or something? These things are just purchase choices. Might as well complain about wallpaper. Something done both functional and pretty. Sometimes "pretty" is very useful in the household environment, where someone (nobody named) insists on the station "looking good" or moving "that mess" to the unheated garage. A lot of matching speakers have been sold over eight decades, as in back to the 1940's matching speaker for a National NC-2-40-D and its sibling variants, which was a good looking ginormous heavy matching style boat anchor electromagnet speaker near as big as the 240D. http://www.tuberadio.com/240d/240D.html Note the matching feet. Great sound by the way, for listening to AM music broadcast. Magnet current for the electromagnet in the speaker came from the radio. Manufacturers make those things because customers want them and buy them. Just to name a few of the many more, Collins had a matching speaker for the gold dust twins and then for the S line. Heathkit's SB series had a matching speaker SB600 which could hold the power supply for an SB100/101/102 transceiver. This goes on without a break to the current day. I'm sure Wayne had a huge stack of requests to justify the business expense. He ain't building anything without a market. (We should have figured that out by now.) There's a long, long tradition very firmly behind visually matching speaker units. And then one must remember that a lot of people voted for these with their wallets. If they want to buy it, and if it ain't illegal, poisonous, explosive, or whatever dangerous, why not? To my way of thinking, it's just another thing that keeps our manufacturer profitable, and therefore still in business. I like that "still in business" thing. Means I'm still getting new development, fixes, etc. 73, Guy From wes at triconet.org Tue Sep 15 10:10:52 2015 From: wes at triconet.org (Wes (N7WS)) Date: Tue, 15 Sep 2015 07:10:52 -0700 Subject: [Elecraft] K3 to IC-7800 Comparison?

She says the difference in memory options, e.g., 16/32/64 GB, had an actual cost difference of US$1. But the marketing group turned it into $100 difference - and people pay. She said the engineering group incorrectly believed no one would fall for it! Regarding radio speakers, I currently use out of production Dell computer speakers, left overs from work: http://www.amazon.com/Dell-A525-Computer-Speakers-Subwoofer/dp/B000GSVPLO which are great with K3 and also listening to streaming music, youtube, etc. They cost well under $100. If pair of Elecraft speakers cost 4x as much & offer 4x as much (any specs yet?), it's a good deal. But aesthetic value is uniquely personal - which is why such a long thread! For me, Dell will likely be fine. :-) 73, Mike ab3ap On 09/15/2015 09:00 AM, Jim Bolit wrote: > Cost and price are "loosely coupled". > Apple products are a perfect example of this > JimW6AIM From roncerra at earthlink.net Tue Sep 15 10:58:12 2015 From: roncerra at earthlink.net (KM4VX) Date: Tue, 15 Sep 2015 07:58:12 -0700 (MST) Subject: [Elecraft] KX3/PX3/KXPA100AT Message-ID: <1442329092707-7607705.post@n2.nabble.com> I am no longer offering this setup for sale.

However, I see the very same waveform on receive in the P3 today. Why can't I see that waveform from my transmitter on the P3? Plus, the required RF sample and IF frequency data is being delivered by the radio to the P3 for tuning right now, isn't it? I had the desired functionality on my Heath station 35 years ago. When I saw the "probe" hole in the P3 5 years ago I certainly expected similar capability to what I was accustomed in the analog SB610 to be delivered in the digital P3. However, expectation and reality of product features are only my personal opinion and nothing more. As it is, I waited five years and spent $200 to replace a 17 inch piece of wire. I also cleared 12 inches of shelf space at my operating position by removing the O'scope from it and returning it to the bench. Theoretically, I could even reclaim another three and a quarter inches by removing my Autek WM1 and simply use TX-MON's built in wattmeter feature, sell the Autek and recover more than half of the cost of TX-MON. I shouldn't have assumed that the SDR functionality within P3 would have allowed both time and frequency domain displays of transmitted waveforms, even though I can see time domain waveforms on receive in both SSB and RTTY today. When I want to see my transmitted waveform, I will just rig up a serial switch to disconnect the serial port to P3 and view them that way at a reduced level via IF bleed through. Or just use my WinRadio SDR receiver as a SA. Just seems silly to have to do all of that when I have a P3 just sitting there... -lu - W4LT PS: I will just move on now with this thread. No sense in beating a dead horse. You Wrote: The displays generated by K0SM are frequency domain ... TX MON is strictly a time domain (amplitude) display. TX Mon uses a amplitude detector driven by a directional coupler. To do what you desire would require an SDR tuned by frequency data (TX frequency) from the K3. The difference between an envelope (diode) detector and a tracking SDR is a couple of orders of magnitude in both cost and complexity.

The P3 specifications make it clear that one should not have expected that. Even if one were to add input switching to select between a directional coupler sample in transmit and the IF in receive, the frequency range of the P3 is limited to 21.7 MHz. It could not cover the entire 100 KHz to 54 MHz of the base K3 much less the 2 meter transverter. > Or just use my WinRadio SDR receiver as a SA.

For Jim K9YC: Hi Jim, Many thanks for the post on my presentations at the club meeting on Saturday September 5. To quote: "There's an important caveat to his work. The NPR measurements require very sophisticated band-stop filters in his instrumentation setup, and based on the filters he has been able to source, that limits the frequency range where he can do his measurements. An example is in the footnote for the Flex-6700, which has no preselector for the range where he had to do his measurements, which may have caused that radio to measure worse than it would on the ham bands." The instrumentation I use for NPR testing is re-purposed telecom test equipment, as described in my Web article and also in my article in QEX for March/April 2015. I rely on the surplus market for the test sets, and also for the filter pairs (bandstop and bandpass). The bandstop filters typically have 95 dB stopband attenuation and ~ 3 kHz stopband width. A number of these filters are on (or near) amateur bands, e.g. 1940, 3886, 5340, 7600 and 11700 kHz. The first filter pair I acquired was on 5340 kHz, so all the test data in my web article are on this frequency (which is in the 60m band). The Flex-6700 does not have a preselector for this band, so the noise loading will hit the front end and the ADC harder. This will degrade the NPR reading by a few dB, but it will show how the receiver behaves if heavily loaded on a band for which no preselector is fitted. As I picked up additional filters, the number of frequencies on which I run the test has steadily increased.

Yes, but in doing so, he's making it clear that his work does not contribute useful information to a ham trying to evaluate the relative performance of radios in a strong signal environment, AND that's what the measurement is designed to show -- IF the same level of test signal is applied to all of the radios. For me, primarily a contester, secondarily a DXer, the primary factors in choosing a radio are performance in a strong signal environment, a clean TX signal, and a very efficient user interface. After hearing Adam speak, I had hoped that his work would contribute to that process, but because the level of his excitation varies depending on the shortcomings of the radio, it fails to provide useful information. To clarify -- the strong signal performance and dynamic range of SDRs is limited by the total voltage at the input to the digital system. If there is no input filtering (i.e., a preselector, bandpass filter, or hardware attenuator), the digital system sees the broadband spectrum from whatever antenna drives it. That's everything from DC to daylight -- AM broadcast, all the other ham bands, shortwave broadcast, all other users of the spectrum. It is the SUM of all of those signals that combine to overload the digital system. When that combined signal level hits digital clip (all bits are digital zero), the radio stops working. It is, of course, possible for the user to add bandpass filters outboard to the radio, and many contesters with SO2R and multi-transmitter stations do so. This would, indeed, significantly reduce the input to the digital system to inband signals. BUT -- SO2R and multi-transmitter stations with closely spaced antennas could still overload the digital system even with that filtering. And there's still in-band QRM to get you to digital clip -- a ham a block or two away running power amp, or a mile away with his antenna pointed at you, and the sum of all the in-band signals during a major contest. In EU and AS, there are big broadcast signals in parts of the 40M band that are going to sail right through the world's best preselector or bandpass filter without attenuation. My neighbor W6DRX (0.3 miles from me and an active contester) and I both bought K3s as soon as the radio was announced because we realized that it was the only way we could coexist and remain friends. :) 73, Jim K9YC From wa2si at arrl.net Tue Sep 15 13:15:26 2015 From: wa2si at arrl.net (Bert Craig) Date: Tue, 15 Sep 2015 13:15:26 -0400 Subject: [Elecraft] K3 to IC-7800 Comparison?

With all due respect... Personally I have a problem with handicapping or dumbing down measurements just so they fly under a known weakness of certain classes of SDR. That turns the measurements into a perverse "radio Special Olympics" designed to not embarrass handicapped radios. Either the radio can stand the mustard at the high levels with all the rest of the radios or they can't. An RX hitting a wall at a given point because there is now A/D clipping, or for any other reason, is a valid should-be-reported characteristic of the RX. Put it out there like that. No problem with putting down the number and adding why. Just don't tell why and then NOT tell the number by burying that decision in "adjusted" testing parameters. Not every one has to put up with the kind of signal levels found at multi/multi contest stations or with the overload from monster HF antennas or a naval ship-to-shore station with Godzilla transmitters in the area or other hams effectively next door. Some in common-enough better circumstances will have an absolute wonderful time with less than a top-of-the-list radio, even if there is a 10 dB weakness on some measurement. Put it out there and let people chose. They can read the numbers for themselves and figure out what they mean for themselves. Then the sales receipts can inform companies if they need to kick their research and engineering departments to make some improvements. People who want the radio with the top specs (whether they actually NEED that or not is a separate issue) are going to be very suspicious of dumbed-down measurements. And once the word on dumbing-down is out, it's out, no recalling. Just tell it like it is, no pulling of punches. Tough tests are what improve the craft. For technical reasons, Elecraft is the best thing to happen to ham radio's radios in quite a while, and that's *all* brands I'm talking about. Nothing like getting your b*tt whupped in the market place or high-profile contest arenas to tell you it's time to invest in some improvements that clearly a very big crowd cares about. A test designed to make everyone feel good about what they bought is like T-ball for the tots. T-ball is really great for the little kids. Love to watch 'em. But the top of the Sherwood list is the major leagues. There are those that will make the "post-season" and those that will go home. In the playoffs you make the pitches, you make the plays, you get the hits, or you go home. No underhand pitches because the batter is hurt and can't swing hard. 73, Guy > > On 9/15/2015 6:04 AM, Jim Bolit wrote: > >> Adam, >> You are digging a deeper hole........... >> JimW6AIM >> > From eric at elecraft.com Tue Sep 15 14:33:09 2015 From: eric at elecraft.com (Eric Swartz - WA6HHQ, Elecraft) Date: Tue, 15 Sep 2015 11:33:09 -0700 Subject: [Elecraft] K3 to IC-7800 Comparison?

I was more than a little concerned by size and Hold/Tap functions etc - I read all the stuff from Sherwood ,keep reading stories here about KSYN3A wonders. Here is my take - I live in a hot bed of BIG time DXers and contesters - it takes quite a receiver to hold up when they all get going .I need a rig I can use when they are on. One guy about 4 miles away has K3/ALPHA8410 - and puts a measured 75 millivolts into the K3 ant jack on 160. I can copy and work weak DX with a 2khz split ? (250hz 8pole) I kind of know he is there ,(no doubt about it looking at P3) but stuff is copyable. (I can see his carrier on a scope on my antenna input , that?s something like S9+65dB) Another guy about 2 miles farther away has a bit better TX antenna and is usually within plus/minus 1 dB of the closer guy ? but he is painful +/- 15 khz- and 30 dB of external pad does not make it go away. Its NOT my K3 RX. (he DID find an arcing filter last year that was making him +/- 50 khz or worse ) I do really wonder what I would notice with KSYN3As on my main /sub rx - I live in a ?field of RF noise? even before the big guns. I DO really like both main and sub rx now truly being fed by same LO. So I am a happy camper PLUS Elecraft support has been BEYOND superb ? I have found no-one to begin to compare. I could go on with a page of my experiences with other vendors. My K3 ?feels? smooth to me ? every bit as ?smooth? as the Orions were - Just hope Elecraft lasts longer than I do !!!!

I articulated my priorities so that readers might evaluate my concern with the strong signal handling issue and user interface. A more casual operator might place a far lower priority on those factors, and as a result be quite happy with an SDR. When I take the time to write an explanation of concepts, it's directed at those who are less technical, with the intent of helping them develop a BS filter, or to generally expand their knowledge. Others have done that for me. A few who come to mind are you, Adam, W4TV, K2AV, N0AX, W8JI, and Wayne. Only last week, W8JI took the time to go through this same issue of front end overload in the context of a preamp. Don't recall whether it was on Tower Talk or Topband. 73, Jim K9YC From wunder at wunderwood.org Tue Sep 15 14:55:03 2015 From: wunder at wunderwood.org (Walter Underwood) Date: Tue, 15 Sep 2015 11:55:03 -0700 Subject: [Elecraft] K3: reverse 12 volt supply In-Reply-To: <55F861E4.1020806@embarqmail.com> References: <009401d0ee98$d6f7fb40$84e7f1c0$@yahoo.com> <55F63A77.7090207@embarqmail.com> <000301d0ef3a$a78b4bd0$f6a1e370$@earthlink.net> <073001d0efb0$06b98b10$142ca130$@carolinaheli.com> <55F81A1D.2090202@embarqmail.com> <55F861E4.1020806@embarqmail.com> Message-ID: <9FF52DB7-A2B3-430E-8CF3-09063378281B@wunderwood.org> Powerwerx has red/black zip cord from 24 gauge to 2 gauge. http://www.powerwerx.com/wire-cable/red-black-zip-cord.html wunder K6WRU CM87wj http://observer.wunderwood.org/ (my blog) > On Sep 15, 2015, at 11:22 AM, Don Wilhelm wrote: > > Dick, > > The Wireman and several other wire distributors have red/black zip cord in a variety of sizes from #24 to #10. > The #12 power wire that is supplied by Elecraft for the K3/K3S and several other legacy kits is the red/black type. > > 73, > Don W3FPR > > On 9/15/2015 1:49 PM, Richard Fjeld wrote: >> I don't know the details of the guys who had the reversals. >> I did a search for paired, stranded, two color wire for power lead use and didn't come up with much. >> Dick, n0ce >> >> > > ______________________________________________________________ > 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 wunder at wunderwood.org From jim at audiosystemsgroup.com Tue Sep 15 14:58:48 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Tue, 15 Sep 2015 11:58:48 -0700 Subject: [Elecraft] K3 RX in real world In-Reply-To: References: <003201d0ef26$b440dd90$1cc298b0$@ij.net> Message-ID: <55F86A68.6010206@audiosystemsgroup.com> On Tue,9/15/2015 11:35 AM, Hank P wrote: > I do really wonder what I would notice with KSYN3As on my main /sub rx - I live in a ?field of RF noise? even before the big guns.

Don't proponents of analog audio point out that when an analog channel overloads, it does so "gracefully"? This is especially true of fans of vacuum tube audio. You can actually tolerate some clipping, as long as it doesn't occur that often. All it does is make the audio sound a little raspier every once in a while, but you can still derive relatively uninterrupted pleasure from, say, the Salzburg recital of Grigory Sokolov playing Rameau's 'Les Sauvages'. This is as opposed to a digital audio system where you can't even tolerate a *single* overload event. Clipping in a digital system is catastrophic and highly disruptive... the audio goes away entirely or becomes so severely distorted that you can't tell if it's Rameau's section in Bb major or the lovely chromatic passage in the turnaround. Similarly, a receiver with an analog front end degrades gracefully. You might get intermod, but you'll probably still be able to copy because intermod simply sounds like more QRM. It's not a sudden collapse. But an all-digital front end is always in danger of failure in a very disturbing way right when it matters most.

All the testing and arguing that has been appearing of late is great, if you are a numbers cruncher and chart maker. But, to my thinking - the technical performance differences between the top rigs can only be discerned in a "copper" room. Real world experience with QRM, QRN, good or poor antennas, band conditions are all the great equalizers. Reported real world experience - comparing one rig (A to B) - is of far greater value to me than a list of numbers. Lots of explanations why one rig is preferred over another: handles QRM/QRN better, has more pleasing audio, better/worse ergonomics, more ??? for the money, too many menus, great audio reports, great keyer/break-in, eye candy, etc. Of course, all that said - it would be a very hard sell to get me away from my K3-Line.

However, at that point they can not withstand any overload. If one decreases the input signal (e.g., turns off the preamplifier) to provide headroom or avoid ADC overflow, the sensitivity (MDS) suffers in direct proportion to the decrease in signal level. ARRL's review of the Flex-6700 and Flex-6300 shows this inescapable fact of nature (law of physics) very clearly. AB4OJ's noise power ratio testing hides the fact by not providing MDS values under each test condition *and* fails to indicate that even with *no preamplifier* the total noise signal is more than 10 dB *less* that that used for testing with traditional superhetrodyne or downcoversion DSP designs. 73, ...

Zip cord is NOT good for ANY application, because it is inherently susceptible to RFI. TWISTED PAIR is FAR better, because it inherently rejects interference from low audio frequencies to at least VHF. In the last few years, I've been replacing more of my DC wiring with twisted pair.

Exactly. Get on during CQWW. I could hear interesting transmitter widths from people half a continent away and interesting effects in my receiver as well (mostly noise blanker effects). I heard this all just on my dipole with no hams close by.

If this is true, it ain't good. You've got the concept right -- the only difference is that 10 dB is not a "hard" number -- it could be anything from 5 to 30 dB, depending on how much test signal strength has been turned down, or preamp gain removed, to get the input of the digital system out of clip! Here are some comments by an engineer i trust. 73, Jim K9YC = = = = = - According to the ARRL, the Flex 6700 has 14 dB worse preamp-off BDR than the K3. - If you turn the Flex's preamp ON, the BDR is probably 24 dB (or more) worse than the K3's. But if you turn the preamp on the 6700 OFF, its 2-kHz IMDDR3 is 8 dB worse than the K3's. You can't win This all stems from the poor NF of their ADC and its low input voltage range. The MDS of the Flex is only -118 dBm (according to Sherwood) with the preamp off. (A K3's MDS with preamp off is -134 dB.) So you have to turn the Flex's preamp ON to get good MDS. The 2-kHz IMDDR is then good, but the BDR is terrible. Sherwood was so baffled by the weird responses he saw that he simply put "A/D Limit" in the BDR column for the Flex. He's still thinking about how to test it. ARRL measured Flex's BDR, but only using the conventional method. To properly assess the damage caused by an ADC at the front end, you have to inject MANY signals into its input to give them a chance to combine in phase and hit the ADC's clipping threshold. And ADCs do NOT gracefully degrade.

Zip cord is NOT good for ANY application, because it is inherently susceptible to RFI. TWISTED PAIR is FAR better, because it inherently rejects interference from low audio frequencies to at least VHF. In the last few years, I've been replacing more of my DC wiring with twisted pair.

For Jim K9YC: Hi Jim, Many thanks for the post on my presentations at the club meeting on Saturday September 5. To quote: "There's an important caveat to his work. The NPR measurements require very sophisticated band-stop filters in his instrumentation setup, and based on the filters he has been able to source, that limits the frequency range where he can do his measurements. An example is in the footnote for the Flex-6700, which has no preselector for the range where he had to do his measurements, which may have caused that radio to measure worse than it would on the ham bands." The instrumentation I use for NPR testing is re-purposed telecom test equipment, as described in my Web article and also in my article in QEX for March/April 2015. I rely on the surplus market for the test sets, and also for the filter pairs (bandstop and bandpass). The bandstop filters typically have 95 dB stopband attenuation and ~ 3 kHz stopband width. A number of these filters are on (or near) amateur bands, e.g. 1940, 3886, 5340, 7600 and 11700 kHz. The first filter pair I acquired was on 5340 kHz, so all the test data in my web article are on this frequency (which is in the 60m band). The Flex-6700 does not have a preselector for this band, so the noise loading will hit the front end and the ADC harder. This will degrade the NPR reading by a few dB, but it will show how the receiver behaves if heavily loaded on a band for which no preselector is fitted. As I picked up additional filters, the number of frequencies on which I run the test has steadily increased. Links to multi-frequency NPR data for various radios (including the K3 with KSYN3A) are on my website: http://www.ab4oj.com/test/main.html#NPR? It was a pleasure meeting you guys over the Labour Day weekend. 73, Adam VA7OJ/AB4OJ ______________________________________________________________ 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 jbollit at outlook.com From kevin.stover at mediacombb.net Tue Sep 15 20:20:13 2015 From: kevin.stover at mediacombb.net (Kevin Stover) Date: Tue, 15 Sep 2015 19:20:13 -0500 Subject: [Elecraft] K3 to IC-7800 Comparison?

This just points out that given problems in hardware have capacity breakout points. We are at a point where pure digital stuff to handle full range alongside a K3 just isn't available at a price even remotely workable, even for high end consumer gear. It might be "close", but it's not at the breakout where those devices are at commodity prices. I remember the days back in the 70's when for commercial computing reasons we would have spent exorbitant money to get our hands on processor speed or storage sizes that I currently have in my iPhone, which is commodity pricing for processor speed and storage size and everything else. Price point A/D range to match a K3S just isn't quite here. One of these years everything will be direct sampling, and it will be very, very good. The features and process simplifications that will flow off that will be awesome. At this point the top extreme range handling boxes are hybrid, both receive and transmit. High end reliable solid state ham HF amps are just now hitting close to 1500 watts. Still rumblings from the contest clubs about solid state amp unreliability. Very touchy, if one exceeds power limits (that are legal to hams) and limited impedance ranges you can blow stuff. So we still have tube amps for brick on key 1500 watts. Our best RX are still hybrid, if you throw ALL the testing at RX with no held back punches, the direct sampling stuff still has issues at certain extremes. But it is close enough that many could use them because their personal environment doesn't tickle those susceptibilities. What bothers me is trying to blow off those specific weakness as if they weren't there. I think that a direct sampling K4 is still pretty "out there". Don't think that stuff is improving on a steep enough curve. But direct sampling that works as well as a K3S *will* happen some day. Apparently needs another 25 dB of sampling range? But it will happen. 73, Guy.

Re: [Elecraft] K3 RX in real world Real World - that is all that really counts. All the testing and arguing that has been appearing of late is great, if you are a numbers cruncher and chart maker. But, to my thinking - the technical performance differences between the top rigs can only be discerned in a "copper" room. Real world experience with QRM, QRN, good or poor antennas, band conditions are all the great equalizers. Reported real world experience - comparing one rig (A to B) - is of far greater value to me than a list of numbers. Lots of explanations why one rig is preferred over another: handles QRM/QRN better, has more pleasing audio, better/worse ergonomics, more ??? for the money, too many menus, great audio reports, great keyer/break-in, eye candy, etc. Of course, all that said - it would be a very hard sell to get me away from my K3-Line.

I agree with you. What I'm saying isn't about why an SDR or an Analog receiver might have problems. If we're testing receivers, we should treat them as a black box and not look into the ciruitry to see how they behave. After the test, then we could look inside and say "oh, the ADC is the limiting factor." 73 -- Lynn From lists at subich.com Tue Sep 15 20:40:18 2015 From: lists at subich.com (Joe Subich, W4TV) Date: Tue, 15 Sep 2015 20:40:18 -0400 Subject: [Elecraft] Analog vs. Digital Front Ends In-Reply-To: <55F89BA5.5030802@audiosystemsgroup.com> References: <55F84C61.90206@audiosystemsgroup.com> <225954794.388912.1442345106214.JavaMail.yahoo@mail.yahoo.com> <55F873E8.3010907@ColdRocksHotBrooms.com> <55F8814C.7020807@subich.com> <55F89BA5.5030802@audiosystemsgroup.com> Message-ID: <55F8BA72.2070609@subich.com> > - According to the ARRL, the Flex 6700 has 14 dB worse preamp-off > BDR than the K3. > > - If you turn the Flex's preamp ON, the BDR is probably 24 dB (or > more) worse than the K3's.

We?ve been refining superhets since 1918, but when I worked on DSP in the 80?s, no one even considered direct sampling. It is still early for direct sampling technology, but it is good enough for people to think about the tradeoffs.

They were originally intended as -additional- lab tools for technical people and those like us here at Elecraft and Flex, ICOM, Yaesu etc to use for evaluation of our designs going forward. We can certainly take additional data in the lab to make these tests even more useful as comparisons between different technologies etc. Your comment about including the mds of the rig and the A/D limit level at the settings used for each of his tests will help a lot though in comparing the results. I'd also like to see that. One other note - the 2.7 kHz SSB filter he used on his test of the K3 (without new synth) does not have as good of a stop band and shape factor as our 2.8 kHz and narrower 8-pole SSB filters. Thereis a big difference between thge two for this type of testing. I'd like to see the noise power test data for a K3 (or K3S) with new synth and an 8 pole 2.8 kHz or narrower filter. We did surprisingly well with the 2.7 kHz 5-pole in his tests. I know what he will see with the 8-pole filter and new low noise Synth. :-) 73, Eric /elecraft.com/ On 9/15/2015 1:36 PM, Joe Subich, W4TV wrote: > > > > On 9/15/2015 3:39 PM, Lynn W.

Now you have the best of both worlds.............what ever "best" happens to be. Belden makes a cable, grey jacket, inside is a foil shield with a drain, and a black and a white twisted, and a #12 strand inside. In this case, one has a shielded twisted pair suitable for 20 amps DC or so. Works quite nice. I use this for my mobile and travel trailer installations.............along with some professional sound installations. I forget the Belden number but if some one needs it, let me know.

My one request to Eric, last year at his presentation at Pacificon, was for a standalone, all-mode transceiver for 2m and above. My rationale was that, since Elecraft sells transverters for 2m, 220 MHz and 432 MHz, they already have the technology to make this possible.

When one makes the same tests and reports the data in the same format the reader is naturally going to compare the numbers of one type of radio (upconversion or downconersion superhet with analog product detector or DSP demodulator) with others (direct digital conversion DSP). It is up to the test designer to make those tests directly comparable *or* very clearly state the difference and why the two can not be compared directly. There is certainly no indication of the differences/incompatibilities in Adam's "Multi-Band NPR Test Results". The difference in test methodologies is documented only in "Noise Power Ratio (NPR) Testing of HF Receivers" and even that document fails to clearly show the differences and *why* the test results of traditional receivers can not be compared directly with those of DDC SDRs. Simply providing MDS for each test condition in each test would go a long way to establishing comparability. Identifying "Ptot dBm" and "Noise Loading dBm" consistently across all receiver topologies *along with* MDS would be even better to establishing a common set of test parameters that would allow the various topologies to be *compared directly* for the ability to copy a signal at the [internal] noise floor in the presence of strong adjacent channel interference which is really what *all* of the receiver comparison tests are about. Real world performance is not about one parameter in a vacuum. > One other note - the 2.7 kHz SSB filter he used on his test of the K3 > (without new synth) does not have as good of a stop band and shape > factor as our 2.8 kHz and narrower 8-pole SSB filters. Actually the tests of K3 S/N 5812 are indicated as using the KSYN3A. However, even comparisons of "analog" receivers are murky ... one needs to look carefully to see than Noise Loading of the Icom 7800 and 7851 *drops* by almost the same amount as the preamp gain (just like a DDC) where the noise loading of the K3 varies by only a small part of the added gain. I won't even point out that the 7800 beats the 7851 on 160 meters - another anomalous result. 73, ...

It also raises a question. If the ADC performance can be so completely destroyed by overloading why would you put it at the antenna where it most likely could be overloaded? With regard to analog front ends, I used to think that antenna tuners were crutches for folk not capable of building resonant antenas. In fact they may serve as analog front ends. Of course they need to be in the signal path to serve on receive. Not all rigs include the ATU in the receiver signal path.

I think it was back around 1993 that there was a discussion on the Internet about using a wide-band ADC to replace the front end of an HF receiver. I commented then that you just couldn't get good enough performance with affordable ADCs available at that time, but someday you might. Time marches on and now ADCs are available that give usable performance at a reasonable price. They still can't compete with a state-of-the-art receiver like a K3, but they are as good as many analog radios of a few decades ago and are quite reasonable for casual operation or even for contesting or DXing if you don't have a very high-signal environment. So how long before ADC technology catches up to the K3? If Moore's law applied (doubling of performance every couple years) it wouldn't be long. Unfortunately Moore's law applies mainly to digital circuitry but the key parts of an ADC are analog (the "A" in "ADC"). Unless there is a big theoretical breakthrough in ADC architecture, I think we still have some years to wait.

Most are repeater users. Seems that a $39 radio model has been proven to be satisfactory to most. The SAT users do require some unique applications to cross band, split frequency and address Doppler shift. The Tropo users need big antennas and lots of power and the EME group even more so. Oh yes, the digital modes make things less complex but still, big antennas, good receivers and clean transmitters is still mandatory. I don't find the current breed of "do it all" radios to have outstanding performance on VHF and UHF. 73 Bob, K4TAX K3S s/n 10,163 On 9/16/2015 6:35 AM, ae4pb at carolinaheli.com wrote: > I still believe it may be possible with the K3S, KRX3 and transceivers to do Full cross band duplex.

The question really boils down to when will we see affordable high voltage ADCs. The problem is that every signal in the input passband is in series and the [peak] voltage adds as a vector sum. So if one S9+63dB (-10 dBm) signal causes the ADC to overflow (consistent with the noise loading limit in the AB4OJ/VA7OJ tests of the Flex-6000 series) the ADC limit is 0.1V (peak) at the antenna. Spread that 0.1V across multiple [equal strength] signals and you see the following: N "S" ---------------------------------- 1 S9 +63 dB (-10 dBm) 3 S9 +53 dB 10 S9 +43 dB 32 S9 +33 dB 100 S9 +23 dB 316 S9 +13 dB ~450 S9 +10 dB 1000 S9 +3 dB ~1400 S9 +0 dB (-73 dBm) Since it is the instantaneous peaks that cause problems, increasing the number of signals decreases the frequency of the ADC overflows. There is certainly analysis that can be done to compute the probability of a peak given a specific number of signals and frequency distribution but my best guess is that the number of signals involved will be somewhere between 10 and 100. Of course, if one of those signals is very strong - a 1.5 KW neighbor 0.5 miles away or a broadcast station that puts a few volts on any wire in the air - it does not take many (if any) additional S9+10 dB signals to push the system over the edge. 73, ...

If one wanted a ham band RX using an A/D front end, certainly one would add front end filters. Of course, that would only help solve the problem with out of band signals. Handling the vector sum of in band signals would still have to be designed for. The concept however is a good one. Who knows where these A/D chips will be in 2, 5 or 10 years. I remember when GPS was in its infancy. Many people thought it was crazy to think that a bunch of low orbit non-geosynchronous satellites could be used for extremely accurate positioning. Besides the ground equipment required would be too expensive for most users.

Not true - the Flex-6300 has no preselectors. Even if the transceiver includes preselectors (bandpass filters), defining a second "slice receiver" on a different band causes the preselector to be bypassed. The preselector (most of which are not very "tight") only works when operations are confined to a single band. Those who live in RF quiet locations - no nearby neighbors, no MF or HF broadcast, etc. - can get away with current direct sampling SDRs just like those in quiet locations can get away with an IC-706 or 7000. The *real performance* of the direct sampling technology is equivalent to a moderate performance conventional transceiver with broadband IF panadapter. 73, ...

What drove the market for the present ones?" The driver for the current generation, based on limited information, is the technical requirements for cellular base stations. Perhaps as we move from the current generation to the next generation of mobile devices, we'll see a need arise for better base station performance. To get another 15 to 18 dB of blocking dynamic range (BDR), we need 3 more effective bits. This either comes from more bits at conversion time (a 20-bit high-speed ADC instead of a 16-bit), increasing the sampling rate dramatically while maintaining the same effective number of bits (ENOB as it is called in data sheets), or a combination of both. And of course you also need the downstream digital devices, usually field programmable gate arrays (FPGAs) to implement what we think of as the receiver (oscillators and mixers and filters) that can handle the required interfaces at the necessary speeds, and the internal resources to maintain precision). Until there is a viable market for a large number of such ADCs, semiconductor manufacturers are unlikely to invest a lot in R and D to get there. At this point, they want to compete with each other for the existing market, so they try to offer incremental advantages over their competitors. We may eventually be able to buy ADCs with the required performance to obtain the BDR many of us want and some of us need, but unless there is a large demand for the products whose design needs include ADCs that will provide this performance, there is little incentive for their development.

I don't consider the Flex 6300 as "serious" in terms of a serious contesting radio. I would expect a serious contester to go with the Flex 6500/6700 or ANAN 100 or 200 series. On a crowded band being pounded by strong signals, the direct sampling ANAN rx sounds cleaner to my ears than the K3 or Orion. I don't see the overload issues hypothesized by many on this thread. But maybe I'm wrong. The K3 and Orion are ergonomically superior contesting radios however.

Jim W6AIM -------- Original message -------- From: Lyle Johnson Date: 9/16/2015 9:40 AM (GMT-06:00) To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Analog vs. Digital Front Ends One has to ask, "Which large consumer of high dynamic range, high-speed sampling ADCs is requiring more performance than presently exists? What drove the market for the present ones?" The driver for the current generation, based on limited information, is the technical requirements for cellular base stations. Perhaps as we move from the current generation to the next generation of mobile devices, we'll see a need arise for better base station performance. To get another 15 to 18 dB of blocking dynamic range (BDR), we need 3 more effective bits. This either comes from more bits at conversion time (a 20-bit high-speed ADC instead of a 16-bit), increasing the sampling rate dramatically while maintaining the same effective number of bits (ENOB as it is called in data sheets), or a combination of both. And of course you also need the downstream digital devices, usually field programmable gate arrays (FPGAs) to implement what we think of as the receiver (oscillators and mixers and filters) that can handle the required interfaces at the necessary speeds, and the internal resources to maintain precision). Until there is a viable market for a large number of such ADCs, semiconductor manufacturers are unlikely to invest a lot in R and D to get there. At this point, they want to compete with each other for the existing market, so they try to offer incremental advantages over their competitors. We may eventually be able to buy ADCs with the required performance to obtain the BDR many of us want and some of us need, but unless there is a large demand for the products whose design needs include ADCs that will provide this performance, there is little incentive for their development.

The amplitude distribution of a large number of signals of different frequencies and amplitudes closely approximates Gaussian noise (see note 1 below). As a rule of thumb the peak to RMS voltage ratio of Gaussian noise is about 5 or 6. Of course, theoretically it is infinity, but peaks over about 5-6 are statistically rare (note 2), so that's a good practical rule of thumb. A voltage ratio of 5-6 is 14-15.6 dB. ADC overload should be rare as long as you keep the RMS power 15 dB or so below the ADC full-scale. A lot depends on what happens when the ADC overloads. If it simply clips the signal, an occasional brief overload would not be objectionable. That's how the ADC in the P3 works. On the other hand, if it "wraps around" (for example, 0x7FFF = 32767 wraps to 0x8000 = minus 32768) then it's obviously much more of a problem. In that case, you would need an external analog clipper to keep the ADC from overloading. Alan N1AL Note 1: The Central Limit Theorem: https://en.wikipedia.org/wiki/Central_limit_theorem Note 2: The cumulative Gaussian probability density function is given in the Wikipedia article: https://en.wikipedia.org/wiki/Normal_distribution#Numerical_approximations_for_the_normal_CDF If I calculated right then for x=5, CDF = (1 - 3*10^-8). If the ADC sample rate is 100 Msps, then on average there would be 3 overloaded samples per second. For x=6, CDF = (1 - 2.8*10^-11) so there would be one overload about every 360 seconds.

It is an L-shaped Ikea work table, 30" x 60? for the main top, with some height adjustability. Personally, I find that the lower table top height helps me when typing, particularly, which I do all the time with my logging programs. And maybe it is better, too, for CW keying, though I am a CW neophyte. Ergonomic guidelines are available in many spots on the web, and I wanted to be comfortable. My everyday computer and my radio are on the same desk, so I spend a lot of time there. But you referenced a drawer for ?log books and pencils? ? so you likely hand-write into your log. Then 29? top height would be better. And yes, I second other?s thoughts about positioning the table for access from the rear. I moved my table about 18 inches out from the wall and I appreciate the improved access just about every day if not at least once a week. Your project sounds like you will be creating a work of art. 73, Hoop K9QJS San Juan Island, WA On Sep 16, 2015, at 7:50 , Dennis wrote: I too am beginning to build a new operating desk for use with a K line and several other radios.

Additional receivers will also fit on the first shelf making them an easy reach from the chair in the center of the desk. The desk will be a straight front design, no wrap around curve. I have found through years of experience that building in as much room as possible is the way to go.

Unfortunately, with practical DDC transceivers like the Flex-6000 series, that 15 dB below ADC full scale does very bad things to sensitivity. Based on ARRL's April 2015 test, turning off +20 dB preammp reduces sensitivity (MDS) from -135 dBm to -119 dBm while the 20 KHz IMDDR3 goes from 94 dB (preamp on) to 103 dB (preamp off). In practice, the user is faced with a choice between sensitivity and IMD. The real issue is that the -10 to -17 dBm clip point for the current class of DDC devices is simply too low for full performance from MDS to clipping. Considering that K9ZOA's Norton pre-amplifiers are rated for *+19 dBm* at the 1 dB compression point, a well designed "analog" transceiver has nearly 30 dB more headroom (while maintaining full sensitivity) than the DDC products. This is the issue that the DDC proponents can't escape (and don't want to address). 73, ...

My nine sled dogs were the other primary consideration. We moved from a 5ac lot to 1-3/4ac of which about 1ac is not woods. But moving out of a 1955 owner-built house to a modern 1994 5-star energy home was a good move. In 1955 the area was wilderness and homesteads and nearly roadless. We now live on a lake. My ham shack occupies the 3rd bedroom and is about 11x12 foot. I arranged the two 6-foot folding table in a L-configuration with about 30-inch space between one table and the closet. The closet became a bookshelf. The other table backs to the wall and only window and I have to racks at right angle to the other end of that table so the station forms a U. On the fourth wall is my workbench for electronic assembly. Pretty crowded, now. But leaving the table with space behind holding all the radio equipment makes cable work easier. Thru wall cable opening is at the end of the walkspace. Photos can be seen on my website. My dream shack is a 26 by 18 foot addition to the 2-car garage (separate shop) which I will place my metal/wood working tools in the front third and shack in back 2/3 with dividing wall between and either folding door or pocket door to keep dust from the front area getting to the electronics. This will place the shack facing my 50-foot eme tower about 40-foot away for shorter cables. But my dish is off the other end of the house so farther cable run. I need TV cams for watching the dish even from the current shack so new shack would not be substantially different in operation. But probably need about $25K or more for the dream shack - so still dreaming! 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From rmcgraw at blomand.net Wed Sep 16 16:43:45 2015 From: rmcgraw at blomand.net (Bob McGraw - K4TAX) Date: Wed, 16 Sep 2015 15:43:45 -0500 Subject: [Elecraft] Analog vs. Digital Front Ends In-Reply-To: References: Message-ID: <55F9D481.4040401@blomand.net> As a side note on this topic, there is a company in Tennessee that builds some really nice specialty receivers for various Governments. {notice I stated Governments, as in plural}.

There is absolutely no requirement that a wire be resonant to operate efficiently; especially on receive, which is the case at hand. Any frequency selectivity is due to the matching network, not anything inherent in the piece of wire.

Yes, the blocking dynamic range of direct-sampling receivers using current state-of-the-art ADCs is 15-20 dB worse than a top superhet receiver like a K3. In addition to that, the "soft clipping" of the analog circuitry probably gives some additional advantage to the superhet. On the other hand, for casual operation you don't really need all that dynamic range anyway. A QRP rig based on a NE602 has horrible dynamic range, but you can still make a lot of contacts with it and have a lot of fun.

As long as there are a lot of them, the total has a Gaussian distribution. In fact, it doesn't take very many to get quite close to Gaussian - something like 4 to 6 is generally sufficient if they are roughly equal in amplitude and uncorrelated (different frequencies).

I should have phrased my question more specifically. My intended use for such a transceiver would be weak-signal work. I had the 2m option for the K3 but, with its low power output, I sold it and bought a Kenwood TS-2000X to be dedicated to VHF/UHF operation. However, this type of operation demands high power (at least 100w) and an antenna with high gain, so I would have to buy an external amplifier at any rate. Thus, I might re-think the 2m option from Elecraft. It's a bonus that The K3(S) can handle up to nine transverters. At a convention way back in 2001, I became interested in working the satellites and bought a Yaesu FT-847. The interest waned eventually, so I sold the 847 toward the purchase of the TS-2000X. And no, I don't plan to use the TS-2000X on HF; not when I have a K3 and a K3S. 73 de Jim - AD6CW On 9/16/2015 5:03 AM, Bob McGraw - K4TAX wrote: > I don't view there are many serious VHF and UHF operators today, i.e. > sufficient to warrant a high performance radio.

There is no one answer, because it depends on how much energy from the other transmitters is going to be picked up by your RX antenna. If it enough to operate the COR (you will hear the relay clicking), then you should provide some protection. Providing that protection without actually setting up the proposed Field Day antennas and transmitters and experimenting is the 'safe' way to do it. If you prefer not to do that, I would suggest you do set up a "practice Field Day" with the antennas and transmitters as they will be for the actual Field Day and try it out using all combinations of bands, transmitters and antennas that you plan to use. There may be simulation programs that will tell you how much RF energy is coupled from one antenna to another, but I don't know what those programs might be. 73, Don W3FPR On 9/16/2015 9:45 PM, Ian wrote: > I don't anticipate using a RX antenna any time soon on my K3S but I will use > it at Field Day with 5-4 other 100W transmitters.

Rich is talking about RTTY, which the K3 transmits LSB. On Elecraft radios, use AFSK-A or FSK-D for RTTY, which, I believe, also bypasses the COMP, and sets EQ to a fixed high pass filter with a cutoff in the range of 300 Hz. For all other data modes, use DATA-A, which puts you in USB mode, with COMP off and EQ bypassed or in HPF mode. Also, the K3 runs ALL digital modes including RTTY just fine with VOX. I've never used FSK or PTT. Simplifies things a lot. Rich -- have you turned on the MON so you can hear the audio fed to the TX? Do you hear anything? Are you using VOX or PTT? If VOX, play with VOX GAIN (single push menu) and audio gain (in all digital modes, the Mic Gain becomes Line In gain). Do you see any indication of ALC? You should, and 4-5 bars is where you want to be. Crank VOX and Line In gain. I've got K3s, not K3S, so can't help with USB issues.

That was a bad move. Check the specs on the TS2000X. The K3 has has far better RX specs, and is probably cleaner on TX. All you need to add to a K3 with 2M transverter is a suitable power amp. Look for a vintage ('70s-'80s) Mirage or RF Concepts brick that drives to about 150W with 2W or 10W drive. A year or so ago, I found two of each just by asking on the reflectors of a couple of local ham clubs. I kept one of each and gave the others to a friend. I really appreciate the K3 RX while working weak signal CW and digital modes on VHF. I'm using a vintage Elecraft 2M transverter that I bought more than 10 years ago. 73, Jim K9YC From rwhitetexas at verizon.net Wed Sep 16 23:58:58 2015 From: rwhitetexas at verizon.net (W5RDW) Date: Wed, 16 Sep 2015 20:58:58 -0700 (MST) Subject: [Elecraft] KPA500 (S/N 82) Power Out Problem....

I don't use MMVARI, but MMTTY has two .ini files that try very hard to set your tones to the 2125 pair. I like low tones. To beat that, you need to go into the directories where MMTTY is running, find those .ini files (plain text) and change all the default tones to what you want to use. The two files are mmtty.ini and userpara.ini The statements you're looking for are DefMarkFreq=2.125000e+03 It occurs about 10 times in userpara.ini, only once in mmtty.ini userpara.ini is the file that defines the many decoding options; when you cycle through them, all of those parameters, including the tone frequencies, gets reset. If you have multiple instances of MMTTY, you need to edit these files in each directory. 73, Jim K9YC From mjwetzel at comcast.net Thu Sep 17 00:58:58 2015 From: mjwetzel at comcast.net (Mike Wetzel) Date: Thu, 17 Sep 2015 00:58:58 -0400 Subject: [Elecraft] WTB KDVR3 Message-ID: <67DF7661590F424E83DD17BB86452C6A@rockne> Looking for a KDVR3 for one of my K3's.

I have antennas and equipment for 50/144/222/432/900/1296/2400/3400/10,368 MHz I do eme on 144 and 1296 and building for 50 and 3400 eme. Being in Alaska really is in the VHF wilderness as there are few stations interested in weak-signal. Thus use of satellite in 1980 - 2002 when the phase-3 sats were functioning (high orbit linear transponders). I bought a FT-847 in 1998 specifically for satellite and it worked well. Later I used it for 2m-eme, but it was not especially good on HF. So about 2008 I determined a better approach was to acquire a very-good HF radio and marry it to good transverters to get best performance on VHF+. In 2010 I bought the K3/10 and a DEMI 144-28 transverter. I had used/built some of their kits before (first in 1996), so I decided to get the full line from 144 to 1296. I had already purchase a 10-GHz transverter and two 3456 transverter kits in 1999 (finally built one 3400-144 kit this spring). The new L-series transverters from DEMI came out in 2010 so I upgraded to that model 144-1296. They work very well with the K3. In my not-modest opinion they come close to the best combo one can buy (db6nt is better but at over twice the cost). I sold my FT-847, reluctantly, but that financed my 222 and 432 transverters. I'm not convinced trading a FT-847 for the TS2000x is necessarily a step up - but I never have used the Kenwood radio. I am certain my K3+transverters will run circles around the Kenwood. Of course its not all in one big box. About three years ago I began building DEMI transverters for hams as a (very) small business. I am now building the whole line from 50-MHz to 10-GHz. Almost getting too busy - but no complaints as what I make, funds my hobby. I have come to conclusion that I enjoy the design/construction part of the hobby as much as operating (maybe more). I am well into my new design main station control panel which should improve my reliability factor plus concentrates some of the multiple box syndrome. One of my long-range projects is to marry the K3 and KX3 into a cross-band satellite system: KX3-2M and K3 + higher band transverter (432 or 1268 or 2401 or 10450). New satellites coming soon will bring back needs for multi-mode VHF equipment (P3E may actually get launched). Long answer but I can agree with Bob and Jim. 73, Ed - KL7UW -------------- From: Jim Lowman To: elecraft at mailman.qth.net Subject: Re: [Elecraft] On VHF & UHF radios Message-ID: <55FA00DA.1040705 at sbcglobal.net> Content-Type: text/plain; charset=utf-8; format=flowed That could be, Bob. I should have phrased my question more specifically. My intended use for such a transceiver would be weak-signal work. I had the 2m option for the K3 but, with its low power output, I sold it and bought a Kenwood TS-2000X to be dedicated to VHF/UHF operation. However, this type of operation demands high power (at least 100w) and an antenna with high gain, so I would have to buy an external amplifier at any rate. Thus, I might re-think the 2m option from Elecraft. It's a bonus that The K3(S) can handle up to nine transverters. At a convention way back in 2001, I became interested in working the satellites and bought a Yaesu FT-847. The interest waned eventually, so I sold the 847 toward the purchase of the TS-2000X. And no, I don't plan to use the TS-2000X on HF; not when I have a K3 and a K3S. 73 de Jim - AD6CW On 9/16/2015 5:03 AM, Bob McGraw - K4TAX wrote: > I don't view there are many serious VHF and UHF operators today, i.e. > sufficient to warrant a high performance radio.

Wear surgical/rubber gloves - During assembly I suggest wearing thin rubber gloves (lowes, home depot..etc.. ). That helps keep oil/fingerprints off of everything and you get a slight better grip. 2. Use a magnetic parts tray - even for the SS hardware it helps as they have some slight carbon content. 3. Use a magnetic tipped screwdriver. 4. User gravity to put/keep washers on the screws - don't be afraid to pick up the assembly you're working on and position it such that gravity helps keep parts where they need to be. Keep it Simply Simple. 5. Work in a well-lighted area and I'd even suggest a desk/work lamp. I have plenty of light in my office and the addition of a desk lamp made a dramatic difference to my work. 6. Don't mix bags - keep hardware from one bag in it's own container. Don't mix zinc and stainless J 7. Don't be distracted - ask the wife, kids, pets, ..etc.. to leave you be for a bit.

I hope the rest of the assembly goes well and you find no problems. Is there a chance that your TCXO is already mounted on the KREF3 board? My only comment is that I do not like to have any magnetic tools or trays (or anything else magnetic) on my workbench. They pick up bits and pieces that I do not intend and can sometimes inadvertently operate relays when not wanted. Of course, I am working with a variety of equipment, so my situation is different than only assembling a K3S, and I do have little bits and pieces (cutoff leads, etc) laying around on my workbench. Speaker magnets are an irritation that I can do little about, so I place them away from my work area. I do keep an old Weller soldering gun next to the workbench and its only task is to demagnetize my tools when they begin picking up bits. 73, Don W3FPR On 9/17/2015 8:30 AM, ae4pb at carolinaheli.com wrote: > 2.

I copied the front/back panel pics from the elecraft site and scaled to the actual dimensions & printed. I then pasted these on the front/back of the cardboard mockups. I then moved them around, picturing how everything would go together. Helped a lot on cable flow, especially for the coax. The final setup was totally different than I first pictured! Its a bit of work, but it saved a LOT of rework in the end. Be sure to consider where exhaust fans need clearance, etc. Sit in front of the "rig", reach for "knobs", etc. See how the total setup feels before you start cutting wood Steve AD0ES On 09/17/2015 08:57 AM, elecraft-request at mailman.qth.net wrote: > From: "Chuck Milam, N9KY" > To: bruce > Sent: Thursday, September 17, 2015 9:15 AM > Subject: Re: [Elecraft] Ham Shack Arrangements - just a little OT > > I've really enjoyed the conversation about shack and desktop setups, as I'm > about to get into the garage, get behind the saw, and build a desktop > equipment shelf. > > I've been talked out of building vertical supports, thanks to this > list.?

If you are working with plywood, a normal maximum length for a bookcase shelf of 3/4 plywood is 32 inches without interim supports. If the shelf is going to be longer than that, or you will have substantial weight on the shelf, glue 1 1/4 or 1 1/2 inch high edging strips of 3/4 inch thick solid wood to the front and back to conceal the plywood edges. To keep the shelf assembly from racking, rabbet the back of the assembly and fasten in a 1/4 inch plywood back - then cut large slots (at least 3 inches wide leaving 2 1/2 inches of material at the ends and under the top) in that back panel to provide adequate ventilation and space to pass cables through. I have had considerable woodworking experience both as a hobby with 10 years running a small custom woodworking shop and doing specialty designs for customers. Make it look like furniture - go to a shop that deals in hardwoods and buy quality materials. If you buy at a DIY store, check the materials carefully to be certain sheet goods are flat and the solid materials are not warped. 73, Don W3FPR On 9/17/2015 10:56 AM, Mel Farrer via Elecraft wrote: > Depending on the desk top, the routing of the cables can be a mess.

At present I have a bare room with a lot of scope and I intend to have an operating position on one side and a small construction/repair bench on the other. I was discussing this with a friend and he suggested that to take cables away from the equipment, I could screw a length of industrial cable trunking to the stud wall and butt the operating "desk" to it. To make it more pretty, I could mount a wooden lid on it and cut holes in that whenever a cable is added. I thought about the idea of building a hutch for the K3 and came up with the idea of a top shelf with movable partitions so that I can add to the K-Line as needed. For the cables that will end up outside, I've purchased a 2 inch fitting that's used to make a connection with a fish pond. It comes in two pieces which will clamp either side of the eaves/soffit board and will have a butyl rubber membrane across the entry to prevent the wind from blowing in. From there to a 45 degree 2 inch adaptor and a 2 inch tube (all ABS) so that cables will pass easily from either end. Actual layout of the operating area still to be decided, but at least I have a clean slate. 73, Alan.

The power companies found that one side of the power feed (center tap on 220) to the house or building had to be grounded to prevent voltage buildup on the power lines. In order for the electricians to keep track of the grounded side (neutral) of the power feed they painted the grounded (neutral) wire white. Soon after the wire manufacturers started making both black and white wires so the electricians now could safely wire buildings without resorting to painting the ground wire white. 73 -- Dave Robertson KD1NA From jmlowman at sbcglobal.net Thu Sep 17 13:12:18 2015 From: jmlowman at sbcglobal.net (Jim Lowman) Date: Thu, 17 Sep 2015 10:12:18 -0700 Subject: [Elecraft] Does the K3S/10 have the fans in the case?

It may have sounded ignorant, but I was concerned that there might be RFI and RF in the shack issues, although I couldn't see how MFJ allowed for this and they obviously don't. :-) I will probably sell the MFJ 998 as it has shortcomings for me. It refuses to tune out a bad SWR on some bands and although it should tune with as little as 5 watts, it occasionally insists on QRO from the IC7100 which is fixed at 10 watts for tuning. Obviously the K3 is far superior and allows the user to specify a "sensible" tuning power and it also seems to almost tune fresh air. 73, Alan.

I hope the rest of the assembly goes well and you find no problems. Is there a chance that your TCXO is already mounted on the KREF3 board? My only comment is that I do not like to have any magnetic tools or trays (or anything else magnetic) on my workbench. They pick up bits and pieces that I do not intend and can sometimes inadvertently operate relays when not wanted. Of course, I am working with a variety of equipment, so my situation is different than only assembling a K3S, and I do have little bits and pieces (cutoff leads, etc) laying around on my workbench. Speaker magnets are an irritation that I can do little about, so I place them away from my work area. I do keep an old Weller soldering gun next to the workbench and its only task is to demagnetize my tools when they begin picking up bits. 73, Don W3FPR On 9/17/2015 8:30 AM, ae4pb at carolinaheli.com wrote: > 2.

My woodworking skills are at best poor and more likely nonexistent so cabinetry is out of the question. What I did years ago and has worked out very well was some standard shelving from Lowe'a or HD. Vertical risers screwed into the studding and 18 inch deep brackets mounted on them. Finished the shelves to match the desk top and done. I've been thru a couple of redo's over the years.

I use three K3s and three K2s in my VHF station. I have one Ten Tec OMNI V as well on 432. The big difference between a great HF vs VHF radio is that LO purity and reciprical mixing performance is paramount on VHF, while HF requires the close in dynamic range to be exemplary. I have yet to see a good multi mode or "do all" radio from any manufacturer. I have never used one in my station as a result. Strong signals on VHf can be a huge problem when giant antennas and high locations are in use. Stations 60 or 70 miles away can clobber you very easily. ERP levels can approach 150 KW. I have always been intrigued by the Sherwood numbers for the Kenwood TS-820S and TS-830 with YK88 filters. They don't look so bad in the listing, but they were awful on VHF in strong signal environments with high gain (20 dBd) antennas. Local oscillator noise did not cut it. The K3 with the new synthesizer is about 40 db or more better. I had the Kenwoods back in the 90's and dumped them for K2s and Ten Tec radios. What a difference. The K3 is icing on the cake. I started using them soon after they came out. They are great on VHF and not too shabby on 160 meters also. (heh heh) I don't think I can recall an overload problem with the Elecraft radios or the Ten Tec OMNI for that matter. The OMNI V used crystal oscillators in the 1st LO, so it was pretty clean. The new K3 synthesizer is awesome. It can handle a 0 dBm signal next to a -135 dBm signal and live to tell about it! I have the 144 built in transverter in one of my K3's, but have not used it as it is too low power to drive my big amplifier. Someday I'll resolve that situation and it should work great. Of course VHF contesting is different in different parts of the country. I live in rural Maine about 250 or 275 miles from New York City. I am on the edge of the golden activity corridor. From my place, it is unwise to use multi mode Japanese rigs for serious contesting. Between the deafness and LO phase noise problems, you would have your hands full. Another ham 50 miles away could have a KW and large antenna that was line of sight or almost line of sight, and squash your receiver like a bug. Every VHF band here has a good HF radio for the receiver.

That's how antennas work. If it didn't put RF in your shack it would be a lousy antenna. The key is to RF-proof the gear in your shack. When I operated from a wood frame 2-flat in Chicago, I had a dipole fed with vintage 75 ohm KW twin lead made by Belden (long discontinued). On 80 and 160, I tied both sides of the feedline together and loaded it as a long wire, using a about 150 linear feet of wrought iron fence as a counterpoise. By virtue of the length of the wire and the counterpoise, there was a lot of RF current in my shack, so it coupled inductively to nearby wiring, including the serial cable running from my laptop to my K2. This coupling occurred because the serial cable was parallel wires, and it caused the computer keying circuit from computer to K2 to lock up with as little as 12W. When I replaced that cable with CAT5 (which is four very good twisted pairs) using one pair per signaling circuit, the coupling went away, and I could run my Titan amp at full power with no problems. 73, Jim K9YC From ae4pb at carolinaheli.com Thu Sep 17 14:00:52 2015 From: ae4pb at carolinaheli.com (ae4pb at carolinaheli.com) Date: Thu, 17 Sep 2015 14:00:52 -0400 Subject: [Elecraft] K3 Digital Voice Mode - our future?

My Holux is an older one, but Amazon has a couple newer models there, not too expensive. When you pair and connect the Holux, it shows up as a comport in the Windows device manager. When you launch NMEATime program, you can set its input as either SNTP from the internet, or via a comport from a GPS receiver. I use both. But, when portable I set the Holux out for a clear "sky" view and when the leds on the receiver are showing good GPS connect, NMEA data comes through the comport to the NMEATime program, it locks in and the resulting time clock is right on. I think though you have to purchase the program to get it to sync/change the Windows system time. I purchased mine, so I don't remember. The little battery in the Holux lasts me the whole day. Oh one last thing, I connect a string to the Holux receiver, and run it to the computer, so I do not have to run back to the park, when I realize I left it there...

We also beefed up the KAT500 cabinet to handle the weight of the KPA500. Also, placing it on top of the amp does not raise amp PA transistor temp significantly for most casual duty cycle use, typically raising it a few degrees. In some cases it will cause the amp's fan to move to a higher speed during TX. For higher intensity operation, with the ATU on top of the amp, key down 100% for several minutes the PA temp will raise 5-9 degrees above what its normal operating temp would be without the ATU on top. The fan will also operate at a higher speed. In our testing at normal room temps this was still well below the amp's max temp fault trigger point. But if you plan on RTTY or other high duty cycle modes with a lot of continuous RX time, especially under higher ambient temp conditions, we recommend placing the KAT500 to the side or under the amp. Also, the amp protects itself from over temp situations with its soft and hard fault triggers. So feel free to try it out on top to see how it works under your typical operating conditions. 73, Eric No problems and with my with shack in the basement don't ever recall the fan even going to a higher speed so never experienced a fault. . I do not do the high duty cycle digital modes so once again the answer is "it all depends" . . 73, Bob K2TK ex KN2TKR (1956) & K2TKR On 9/17/2015 2:32 PM, Phil Wheeler wrote: > The manual I have in my computer (from March 2014) says on Page 10: > > 0. > > Positioning the Amplifier > > Provide at least 2 inches (5 cm) clearance > behind the fan and 1 inch (2.5 cm) above the > amplifier for normal cooling air flow. > > Microsoft Word - KPA500 Owner's man Rev D.doc So if I placed the KAT500 atop > the KPA500 I would use some spacers in each corner area.

Furthermore, I recall that these are proprietary coding schemes. That is not "Ham Radio" in my mind. Ham Radio is "everyone can talk to everyone else", and those digital voice systems where you can only talk to those hams who have purchased the same brand of equipment as you have selected is more like commercial circuits where you want to shut out those who do not 'speak the same language that you do'. I don't think proprietary protocols belong on the ham bands - just my not so humble opinion. Yes, I am also opposed to proprietary data modes. 73, Don W3FPR On 9/17/2015 9:03 PM, Robert Nobis wrote: > Take a look at the digital voice modes that are being used on the VHF and UHF bands: DMR, D-STAR and Fusion. > > From vk5zm at bistre.net Thu Sep 17 21:37:20 2015 From: vk5zm at bistre.net (Matthew Cook) Date: Fri, 18 Sep 2015 11:07:20 +0930 Subject: [Elecraft] K3 Digital Voice Mode - our future?

Unless govt agencies start racking and stacking digtal LMR systems without guard bands then there is no clear advantage. The technical requirements of each receiver goes through the roof with 10k1 systems as it. However there is a strong desire from government agencies to move toward encrypted communications, which is very easy with digital LMR; basically you get it for free. This does not relate to the amateur service. In terms of Digital voice replacing SSB that has a very long long way to go. In truth SSB is very difficult to beat in terms of spectral efficiency. SSB puts just enough power into the right spectrum for near loss less communication. When you try to stuff the equivalent power into a low bit rate digital signal, the energy per bit is quite high, meaning you've got to lower your bit rate substantially until the two powers (SSB and DV) are the same. At this low bit rate (<600bps) there is no avoiding the donald duck or robotic voices at this point. That pesky information theory gets in the way. Lots of great progress has been made in this regard (i.e. Codec2), however it will be a while before the necessary 200-600MHz hard float DSP will be required in a K3S. Besides I'm sure a suitable retrofit DSP module can be squeezed in there somewhere when the time comes. 73 Matthew VK5ZM On 18 September 2015 at 10:33, Robert Nobis wrote: > Take a look at the digital voice modes that are being used on the VHF and > UHF bands: DMR, D-STAR and Fusion. > > > Bob Nobis - N7RJN > n7rjn at nobis.net > > > > On Sep 17, 2015, at 17:49, Richard Fjeld wrote: > > > > I was in to freeDV a year or two ago, and it has a long way to go. > Still, it did work. > > > > I'm told the bandwidth has increased since then from 1200 hertz to 1600 > hertz at present, which will be an improvement. > > At 1200 hertz, voices sounded robotic in nature. it lost sync often > which may, or may not, have been due to the compression. > > > > I haven't heard of the FCC's having ruled on it's mode and/or where if > permitted.

While the "Tune Up" situation has been largely eliminated for "No Tune" amplifiers, there is still the question of how to do a TUNE into an antenna when you have a tuner such as the KAT500 in line - but that tunes into the antenna at reduced power with the Elecraft K-line, and the tune cycle is relatively short. The net that I see of all that is one does not need a precision dummy load for high power levels. At the 100 watt level, I do find a need for precision dummy loads which can be used for lab measurement devices, bu at higher power levels in the normal hamshack, I do not understand a need for a precise 50 ohm non-inductive load (as long as you do not stray too far from that 50 ohm point. In other words, the gallon size "cantenna" dummy loads should suffice for most purposes in the ham shack that I can conceive of - primarily providing a suitable load for a high power transmitter for routine test purposes. Those who do precision measurements at high power levels will have to invest in precision dummy loads, but for typical ham use, I don't think that level of precision is necessary. Such precision comes at a cost. 73, Don W3FPR On 9/17/2015 8:19 PM, Byron Peebles wrote: > I'd love to find Elecraft offering a 500W dummy load to match the K-Line. > No one even makes a sturdy paint can anymore. > > 73, Byron > ______________________________________________________________ > 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 w3fpr at embarqmail.com > From vk5zm at bistre.net Thu Sep 17 22:06:35 2015 From: vk5zm at bistre.net (Matthew Cook) Date: Fri, 18 Sep 2015 11:36:35 +0930 Subject: [Elecraft] Why black is the hot wire In-Reply-To: References: Message-ID: Yes this makes wiring 220V US equipment in foreign countries like VK even more exciting, since we're the other way round...

Ham Radio is "everyone can talk to everyone else", and those digital voice systems where you can only talk to those hams who have purchased the same brand of equipment as you have selected is more like commercial circuits where you want to shut out those who do not 'speak the same language that you do'. I don't think proprietary protocols belong on the ham bands - just my not so humble opinion. Yes, I am also opposed to proprietary data modes. 73, Don W3FPR On 9/17/2015 9:03 PM, Robert Nobis wrote: > Take a look at the digital voice modes that are being used on the VHF and UHF bands: DMR, D-STAR and Fusion. > > ______________________________________________________________ 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 vk1zzgary at gmail.com From rmcgraw at blomand.net Thu Sep 17 22:26:01 2015 From: rmcgraw at blomand.net (Bob McGraw - K4TAX) Date: Thu, 17 Sep 2015 21:26:01 -0500 Subject: [Elecraft] Product Suggestion - 500W Dummy Load In-Reply-To: <55FB6AD4.5090003@embarqmail.com> References: <55FB587B.4020604@arrl.net> <55FB6AD4.5090003@embarqmail.com> Message-ID: <55FB7639.2080309@blomand.net> Don, et al: I do agree that we typically do not need a precision load nor do we likely need a "full legal limit CCS" load. Most loads have a power vs. time de-rating curve. Just following that practice will save on lots of $$ and space. Yes the Cantenna loads are generally suitable. I find the Z to be 50 ohms +/- 10% or so. They will handle legal limit power for 2 or3 minutes and 100 to 300 watt power for almost CCS times. As a rule, they are good for HF and become a bit less so suitable for VHF. I prefer dry loads as they are less "messy" where one uses an oil filled load it seems they all want to weep a bit. Oh my gosh should on kick one over and the lid separate. As a suggestion, solder the lid in place at 3 or 4 locations around the edge. It would do well for folks to consider switching and tuning methods so as not to put a signal on the air. Although this typically can't be done with automatic type tuners, with manual tuners, using an antenna bridge will allow one to adjust the tuner for a proper match and not put a signal on the air. Then with older amps, tuning those into a dummy load again will not put a signal on the air. When the amp is switched to the tuner then all is well and no QRM has been generated. 73 Bob, K4TAX K3S s/n 10,163 On 9/17/2015 8:37 PM, Don Wilhelm wrote: > While a dummy load that has a power rating greater than your maximum > transmit power is a worthwhile addition to any hamshack - at higher > power levels, I do not see them being used as precision measurement > devices, but only as a temporary load for the purposes of "tuning up" > or operating into a dummy load for test purposes. > > While the "Tune Up" situation has been largely eliminated for "No > Tune" amplifiers, there is still the question of how to do a TUNE into > an antenna when you have a tuner such as the KAT500 in line - but that > tunes into the antenna at reduced power with the Elecraft K-line, and > the tune cycle is relatively short. > > The net that I see of all that is one does not need a precision dummy > load for high power levels. > At the 100 watt level, I do find a need for precision dummy loads > which can be used for lab measurement devices, bu at higher power > levels in the normal hamshack, I do not understand a need for a > precise 50 ohm non-inductive load (as long as you do not stray too far > from that 50 ohm point. > > In other words, the gallon size "cantenna" dummy loads should suffice > for most purposes in the ham shack that I can conceive of - primarily > providing a suitable load for a high power transmitter for routine > test purposes. > > Those who do precision measurements at high power levels will have to > invest in precision dummy loads, but for typical ham use, I don't > think that level of precision is necessary.

If it isn't the oil's circulation upward through the tube and past the resistor will be severely limited. The heating and cooling through use -will- cause the can the "breathe" air out and in via the spring loaded vent. This will eventually result in droplets of water collecting in the bottom of the can and will eventually rust a hole and the can will leak. These water droplets can be sucked up with a kitchen baster and Tygon tubing. Replacement gallon cans can usually be obtained from a paint store. It's still a good idea to set the load in a plastic bucket. (:-) As a retired power company employee I'll offer the following about the dangers of PCB-based "transformer oil" from my employer's transformer maintenance folks. It's been many decades since there was PCB-based oil commonly in use and the likely hood of someone coming into the possession of PCB contaminated oil is mostly an urban legend. I've seen men standing chest-deep in oil inside a large substation transformer while doing repair or changing a tap. 73!

I came across a bunch of 620 ohm 20 watt carbon resistors a long time ago. I wired 12 of them in parallel and put them into a gallon can of mineral oil. That dummy load still measures 51 ohms over the bands from 80 thru 10 meters with a minimal amount of inductance - and it is over 40 years after I first built it. I figure since it will do 240 watts in open air, in the oil, it should take the legal limit for relatively short periods, but I have not subjected it to more than 500 watts. Yes, I have heard stories about how the Heath resistors changed value, but my 'substitute' has not changed over the years. 73, Don W3FPR On 9/17/2015 10:36 PM, Fred Jensen wrote: > Strangely, these non-inductive resistors do not last forever.

As far as I know, there was only one edition. If there was a second, then perhaps the errors were corrected. Maybe there is an errata-sheet available But, if one is buying the first edition, be aware that the book is full of mistakes. Three things that come to mind most notably are: 1. the section on band-reject filters. 2. element values for the Cauer designs did not match up to the gold-standard I used; it is regrettable that I cannot recall the name of that book (maybe by Telefunken) because it has been almost twenty years since I used it; personally, I would not trust any Cauer values from Zverev. 3. toward the end of Zverev, his chapter on network transformations (equivalent circuits) has issues as well. I used Zverev from 1970 to 1997 and marked-up in red pencil the mistakes concerning designs on an "as needed" basis. Usually the mistakes were encountered while under a pressure deadline to get a quote out quickly. Not that it probably matters now-a-days but, if you wanted to make a n=6 or n=8 0.05 degree phase-ripple crystal-filter, Zverev does not have it. Zverev's style of writing was to take a simple task and write it up as incredibly complicated as can humanly be done; just my opinion. 73 Jerry KM3K From jmlowman at sbcglobal.net Thu Sep 17 23:40:05 2015 From: jmlowman at sbcglobal.net (jmlowman at sbcglobal.net) Date: Thu, 17 Sep 2015 20:40:05 -0700 (PDT) Subject: [Elecraft] (no subject) Message-ID: <877974.92104.bm@smtp112.sbc.mail.gq1.yahoo.com> Well, Dave, your observations have caused me to take a second look at the K3(S) with transverters for VHF/UHF weak-signal work. The only problem is, an amplifier to bring the 2m power output of the 2m option for the K3(S) up to 120w or so is around $650 (looking at Mirage) and 120w is not all that much power, absent an antenna with very high gain. But your observation as to the number of serious weak-signal operators caused me to do some research. Looking back 10 years to the 2004 June ARRL VHF contest, and comparing it with the results for the same contest in 2014, the total number of stations submitting logs actually increased from 766 to 1,042. I'd have to say that these results show that we still have a good number of serious weak-signal operators. The January VHF contests from the same 10-year span showed a decrease from 833 to 622 logs submitted, but I might attribute that to having a larger number of operators being able to set up shop on mountaintops, whether portable or rover class, due to better weather conditions in June. The sample size of 1,042 goes to prove what Eric (Elecraft) stated about the limited market for a dedicated VHF/UHF transceiver - and these operators obviously have the required equipment already. 73 de Jim - AD6CW On 9/17/2015 10:44 AM, Dave Olean wrote: > There used to be a larger number of "serious weak signal VHF > operators, but the serious VHF operators are all dying off with no > young ones to replace them.

When we see an 'open source' digital voice mode that is published and can be implemented by any amateur, then I may change my position, but that is not the situation today. I do not believe that proprietary modes of any sort should be permitted on the ham bands. One characteristic of digital streaming 'anything' is that if the signal 'loses sync', things go to pot, and you have to wait until it syncs up again. With fading on an analog signal, you can usually fill in the gaps, but with digital, it is all or nothing. When it is "all", it is great, but the gaps are annoying - plus the quality is determined by the bit rate in the encoding/decoding algorithms. 73, Don W3FPR On 9/17/2015 11:16 PM, Sandy wrote: > I could not agree more Don!

The sample size of 1,042 goes to prove what Eric (Elecraft) stated about the limited market for a dedicated VHF/UHF transceiver - and these operators obviously have the required equipment already. 73 de Jim - AD6CW On 9/17/2015 10:44 AM, Dave Olean wrote: > There used to be a larger number of "serious weak signal VHF > operators, but the serious VHF operators are all dying off with no > young ones to replace them.

Remember also that dummy load ratings include a duty cycle. The cheap stuff has a very short duty cycle -- one might be rated 100W for 1 minute. :) It's all about heat -- do you get hot enough to damage it? Duty cycle can be interpreted two ways. One is to use a series of dits to tune up, which gets you to full power but half the time. That's what I do. I just sold a nice little keyer-pulser that W2VJN used to make. Its duty cycle could be adjusted as low as 20%. Another way to interpret it is how LONG you transmit into it. My big professional oil filled dummy load is rated 500W for a long time (don't remember the spec). I transmit dits (and even RTTY) into it at legal limit for a minute or so, and it doesn't overheat. And then I let it cool off. 73, Jim K9YC From wunder at wunderwood.org Fri Sep 18 00:53:15 2015 From: wunder at wunderwood.org (Walter Underwood) Date: Thu, 17 Sep 2015 21:53:15 -0700 Subject: [Elecraft] K3 Digital Voice Mode - our future?

Is anybody addressing the issue of QRM from other stations? I suspect digital will fold -- especially when one is trying to detect one out of many or a station immersed in splatter from one or more stations. The ability of the mind to pull out an individual station in the analog QRMed world would seem to be lost. This is best illustrated by people being able to decode one voice of many at a party. Here the switch to digital TV has been frustrating. Stations which had previously been received acceptably are spotty. The digital cliff effects are a killer. The one station we really like to watch (PBS 55 miles away, two edge diffraction reception) is greatly effected by day/night, the seasons and weather conditions. Admittedly some of degradation is due to the move from VHF to UHF. However I suspect that an analog transmission on the same frequencies would still be watchable. Part of the problem at UHF is enhancement of multipath effects. (Also DTV apparently is transmitting with 6db less power which is supposed to be made up by the digital decoding at the reception end. ) One sees this with a highly directional high gain antenna. A station will drop out and if you bump the antenna a few degrees, it will return and then drop out. It is a dance between the rotor to try to keep a station locked. If these multipath effects are so significant for digital, single signal one might expect the problem to exist in spades on HF. Anybody who has looked at WWV carrier transmissions on a high resolution FFT display can see several distinct signals due to multipath shifted by up to 2 Hz at times. The strongest of the bunch moves from FFT bin to bin. As a side note, those HDTV stations who stayed on low VHF channels have had no end of problems. Apples and oranges perhaps..... 73 de Brian/K3KO On 9/18/2015 2:16 AM, Gary wrote: > Don, > > Absolutely spot on sir. > > Gary > > -----Original Message----- > From: "Don Wilhelm" > Sent: ?18/?09/?2015 11:30 AM > To: "elecraft at mailman.qth.net" > Subject: Re: [Elecraft] K3 Digital Voice Mode - our future? > > You have listed 3 digital voice modes that do not talk to each other. > Furthermore, I recall that these are proprietary coding schemes. > That is not "Ham Radio" in my mind.

If we find an OM out of band or transmitting an out of spec signal we do the neighborly thing and help them fix it. I don't believe anyone (there are lids..other than them) intentionally transmits a poor signal. My view is that much of the younger generation are more into the operational than the "here's out it works and why".

Comparisons with single signal stations seems irrelevant. Is anybody addressing the issue of QRM from other stations? I suspect digital will fold -- especially when one is trying to detect one out of many or a station immersed in splatter from one or more stations. The ability of the mind to pull out an individual station in the analog QRMed world would seem to be lost. This is best illustrated by people being able to decode one voice of many at a party. Here the switch to digital TV has been frustrating. Stations which had previously been received acceptably are spotty. The digital cliff effects are a killer. The one station we really like to watch (PBS 55 miles away, two edge diffraction reception) is greatly effected by day/night, the seasons and weather conditions. Admittedly some of degradation is due to the move from VHF to UHF. However I suspect that an analog transmission on the same frequencies would still be watchable. Part of the problem at UHF is enhancement of multipath effects. (Also DTV apparently is transmitting with 6db less power which is supposed to be made up by the digital decoding at the reception end. ) One sees this with a highly directional high gain antenna. A station will drop out and if you bump the antenna a few degrees, it will return and then drop out. It is a dance between the rotor to try to keep a station locked. If these multipath effects are so significant for digital, single signal one might expect the problem to exist in spades on HF. Anybody who has looked at WWV carrier transmissions on a high resolution FFT display can see several distinct signals due to multipath shifted by up to 2 Hz at times. The strongest of the bunch moves from FFT bin to bin. As a side note, those HDTV stations who stayed on low VHF channels have had no end of problems. Apples and oranges perhaps..... 73 de Brian/K3KO On 9/18/2015 2:16 AM, Gary wrote: > Don, > > Absolutely spot on sir. > > Gary > > -----Original Message----- > From: "Don Wilhelm" > Sent: ?18/?09/?2015 11:30 AM > To: "elecraft at mailman.qth.net" > Subject: Re: [Elecraft] K3 Digital Voice Mode - our future? > > You have listed 3 digital voice modes that do not talk to each other. > Furthermore, I recall that these are proprietary coding schemes. > That is not "Ham Radio" in my mind.

I also do not like proprietary technologies. However, if you look at the history of ham radio, many of the products and technologies we use today started out as ?proprietary? technologies. Also, much of the history of ham radio is based on experimenting and trying new technologies and techniques. At least one of these digital technologies, DMR, is no longer really proprietary. There are at least 20 manufacturers of DMR radios, worldwide. True, DMR was not originally developed for use by hams, but it clearly is a product technology that many hams are now using on the VHF and UHF bands, even though I doubt we will ever see DMR on the HF bands. 73, Bob Nobis - N7RJN n7rjn at nobis.net > On Sep 17, 2015, at 18:28, Don Wilhelm wrote: > > You have listed 3 digital voice modes that do not talk to each other.

Also, Icom has registered the trademark ?D-STAR?. It would be possible to run D-Star with an open source codec (like Codec2), but it probably would not interoperate with other D-Star radios. Codec2 was developed by Dave Rowe, VK5DGR. Some people have argued that the proprietary AMBE codec is equivalent to encryption, and not legal for US amateur radio us.

It's going to depend a whole lot on how it's encoded, the data rate, and how much error detection and correction is used. Bump up the data rate, do some forward error correction and it's likely to be fairly robust. Some of the methods used by NASA to encode signals from deep space probes are incredibly robust. -- Lynn On 9/18/2015 1:18 AM, brian wrote: > Is anybody addressing the issue of QRM from other stations?

DMR uses AMBE, so it's proprietary, because you (apparently; law is hard) can't build and sell a DMR radio without a patent license. An individual ham may not legally homebrew and use a DMR radio without a patent license. One can't distribute Free Software that implements DMR on software radio. There are many vendors, and they seem to mostly interoperate. DMR is much like D-STAR, in that the container protocol is open or mostly open, but the codec is not. This leads to big manufacturers paying patent licenses and individuals buying pre-programmed DSP chips to run the secret code that could have been run in their regular computer, if not for the patent (e.g., the "DV Dongle"). If Elecraft wanted to put D-STAR or DMR into the K3/KX3, besides the work, they would have to get a patent license for the codec. That seems unlikely - and it would make me unhappy to be indirectly paying for something that I think doesn't belong in ham radio (well said, Don) and should not be permitted by the rules. On the other hand, I suspect that implementing D-STAR with codec2 (VHF), or FreeDV, would just be implementation work, with no licenses and no extra hardware. It doesn't seem like there's critical mass yet for that to make sense, though. 73 de n1dam From jermo at carolinaheli.com Fri Sep 18 12:42:32 2015 From: jermo at carolinaheli.com (Jerry Moore) Date: Fri, 18 Sep 2015 12:42:32 -0400 Subject: [Elecraft] K3 Digital Voice Mode - our future?

The D-Star protocol is published and open, but all the radios use a proprietary, licensed voice codec (AMBE). Also, Icom has registered the trademark ?D-STAR?. It would be possible to run D-Star with an open source codec (like Codec2), but it probably would not interoperate with other D-Star radios. Codec2 was developed by Dave Rowe, VK5DGR.

I have to prefer SSB almost every single time. SSB has been around for decades, and we're pretty good at it, but there was a time when people said "I don't begrudge anyone experimenting with SSB, but every time I listen to it, I'm appalled, I'll take AM any day." I'm not arguing for DV just because it's digital. We should get excited about DV when it becomes "better" in some way. Just like the adoption of SSB. In the meantime, we can experiment. 73 -- Lynn From kl7uw at acsalaska.net Fri Sep 18 14:00:12 2015 From: kl7uw at acsalaska.net (Edward R Cole) Date: Fri, 18 Sep 2015 10:00:12 -0800 Subject: [Elecraft] Product Suggestion - 500W Dummy Load Message-ID: <201509181800.t8II0Db2019884@mail42c28.carrierzone.com> Don't have much to say: Had a Cantenna from Heath in the 60's - knocked over; spilt mineral oil on the floor, threw can away! I have acquired "dry" loads over the years rated into UHF and sometimes to mw at flea markets and swaps.

Most can handled double their rating for short duration. The hardest duty on my loads is when optimizing the output of a new unit where I'm keyed up longer than I should. But I do have a question on how adjusting a tuner into a 50-ohm load saves one from transmitting a signal once the tuner is connected to an antenna that may not be 50-ohms. On 600m my inverted-L is Z = 0.8 +j680. Tuning into a 50-ohm load does nothing to help match the antenna. The amplifier is solid state with input and output transformers (no adjustment). I think, unless you use a high power tetrode or triode, that no one tunes amplifiers anymore. Solid state amps are broadband and need LP filters to keep from amplifying harmonics. BTW my 2m-8877 is capable of 2000w* RF output so pretty hard to find a dummy load to take that. Fortunately the amp does not change much so very little tuning is ever needed (of course I am on a small segment of one band about 200-KHz wide). Of course the answer is to tune antenna at lower power and hope the High Power amp will always be looking at 50-ohms. I do not have a QRO 2m antenna tuner but the antenna SWR < 1.25 so only the anode tuning needs a light adjustment occasionally (loading has not be adjusted for 8 years).

Message-ID: <201509181816.t8IIGfQ1002382@mail42c28.carrierzone.com> Most VHF operators learn that there are good deals in used amps. I only have one 180w 2m amp that I bought new (in 1976). All the others were bought from other hams. But one can build an amp vs buying overpriced Mirage junk. Look at the 80w 2m kit that W6PQL offers. I have actually done a little research into making some of them FS. Definitely under $600. In fact probably less than 50% that. I have broached the idea of combining two for 160w with Jim Klitzing (W6PQL). He sells assembled amps, too. BTW that 180w amp in 1976 was a "Klitzing" back when he was just a local CA builder (and I lived in greater LA) I have a used Mirage A1015G (6m-150w), used RFConcepts 2-30 (25w which I drive with my KX3-2M), used RFC 2-317 170w, two used 150w Securitor 222-MHz amps, used BU150 432-MHz 150w, kit for a 75-90w 432 amp (yet to build), HF amp from a TS50, two 1296 150w W6PQL amp kits, and two nib Toshiba 60w 3400-MHz amps. That's not counting my 300w and 140w HF amps from kits by CCI. I think the 6m amp cost the most ($230 or so off e-bay). 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From ae4pb at carolinaheli.com Fri Sep 18 14:16:59 2015 From: ae4pb at carolinaheli.com (ae4pb at carolinaheli.com) Date: Fri, 18 Sep 2015 14:16:59 -0400 Subject: [Elecraft] Product Suggestion - 500W Dummy Load In-Reply-To: <201509181800.t8II0Db2019884@mail42c28.carrierzone.com> References: <201509181800.t8II0Db2019884@mail42c28.carrierzone.com> Message-ID: <04c201d0f23e$36edc270$a4c94750$@carolinaheli.com> Forgive me in advance if this is a stupid question. Is there any reason you have to tune at full power? It seems to me that tuning can be accomplished easily with much lower power. The same thing goes for the ATU to the antenna. I don't see why we need more than a few MW at most for the ATU to Antenna link. Rightly or wrongly when I was in the hobby the first time I ran a TS-850 into an SB-220 to an MFJ roller tuner connected to an antenna switch feeding: 80m inverted V, 30m/40m rotatable dipoles, and a triband beam. Whenever I tuned on the inverted V or outer band limits of where my antennas where tuned I ended up putting labels on the ATU on cap position and a number/clock combo that represented a roller inductor position for each band area I cared about. It ended up I rarely had to tune up anything one the air because I knew where the antenna tuning was using just the Rig and ATU; tuned the APM into a paintcan MFJ load then switch it inline. I was all set and never had issues when I needed to kick in the horses. Now my debate is 500w vs 800w... there's a larger difference between 500w and 800w than between 800w and 2.5kw signal wise if I understand correctly...

My "dummy load" has 19.2 dBd gain and radiates well. *I operate at 1365w CW which allows for about 9% variance in meter accuracy to stay legal. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa 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 jermo at carolinaheli.com From w6jhb at me.com Fri Sep 18 14:37:10 2015 From: w6jhb at me.com (James Bennett) Date: Fri, 18 Sep 2015 11:37:10 -0700 Subject: [Elecraft] Serious weak-signal VHF operators?

Is there any reason you have to tune at full power? It seems to me that tuning can be accomplished easily with much lower power. The same thing goes for the ATU to the antenna. I don't see why we need more than a few MW at most for the ATU to Antenna link. Rightly or wrongly when I was in the hobby the first time I ran a TS-850 into an SB-220 to an MFJ roller tuner connected to an antenna switch feeding: 80m inverted V, 30m/40m rotatable dipoles, and a triband beam. Whenever I tuned on the inverted V or outer band limits of where my antennas where tuned I ended up putting labels on the ATU on cap position and a number/clock combo that represented a roller inductor position for each band area I cared about. It ended up I rarely had to tune up anything one the air because I knew where the antenna tuning was using just the Rig and ATU; tuned the APM into a paintcan MFJ load then switch it inline. I was all set and never had issues when I needed to kick in the horses. Now my debate is 500w vs 800w... there's a larger difference between 500w and 800w than between 800w and 2.5kw signal wise if I understand correctly...

Message-ID: Working with my newly constructed K3S today, I noticed that receiving through the FL4 crystal filter (400 hz, 8-pole) was noticeably suppressed. Through the FL3 (1.8 kHz) filter, an RTTY signal would be nice and strong with good S-meter indications. Going to 400 Hz the signal would nearly be lost and I could not decode it. Going to FL5 (250 Hz), the S-meter would pick up again with strong signals. There's not much to check on the Config menu except the FL4 GN and it's at max (8 db) - not much change.

Wasn't CCS but okay for my purposes. Using the loss in coax for an attenuator isn't unheard of. When I was still in the work force I once had to test some cables with 100 Watts applied at elevated temperature (+85C) and VSWR = 3:1 @10GHz. For a load I used about four feet of 0.085" semi-rigid coax (3 dB loss) shorted at the end (6 dB return loss) coiled up in a can of water for a load. An amazing tribute to the Hughes TWTA (and its circulator) that ran for over a hundred hours during this test.

Absolutely. The dynamic impedance of the tube varies with power level. Tube amps should ALWAYS be tuned at full power AND with the actual load attached. K6XX has observed that the distortion rises when the load is not matched to the amplifier. To do that without overstressing the tube, I always tune with dits. I never tune with a dummy load except when testing a radio or amp. Instead, I have created a "cheat sheet" of amplifier tuning settings for every band and every antenna, so that when I start tuning, I'm close. I always find a clear frequency, send my dits, and get out of the way fast. :) 73, Jim K9YC From jim at audiosystemsgroup.com Fri Sep 18 17:30:49 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Fri, 18 Sep 2015 14:30:49 -0700 Subject: [Elecraft] (no subject) In-Reply-To: <55FC781B.2070107@triconet.org> References: <877974.92104.bm@smtp112.sbc.mail.gq1.yahoo.com> <55FBA16D.4010805@audiosystemsgroup.com> <55FC781B.2070107@triconet.org> Message-ID: <55FC8289.6080207@audiosystemsgroup.com> On Fri,9/18/2015 1:46 PM, Wes (N7WS) wrote: > My experience (admittedly ancient) is that good quality and Mirage > said in the same sentence is an oxymoron, or in other words, a mirage.

The ublox Neo-7 GPS is a lousy frequency reference in most respects, except that it is accurate in keeping exactly 10 million periods per second. My experience is that the K3 has enough internal averaging to deal with that. Using a ublox Neo-7 (USD 12 on Ebay) and a 74HC04 as a driver to feed the 10 MHz to the 50 ohm input of the K3EXREF the K3 accepts the input and I see the star in REF*CAL blinking. The reference frequency now starts at 49,379,680 and stabilizes to 49,279,650 after some 15-20 minutes. My initial setting for the reference was 49,379,640 which I determined manually when the K3 was new in 2009 or so. I am going to write this up on my blog with schematics eventually.

I have an early K3 equipped with the K3EXREF Frequency Lock Option, K144XV Two Meter Module and K144XV Reference Oscillator Phase Lock Option. Some time after installing the KSYN3A synthesizers I noticed that the 144 Mhz band has a 5.6 KHz frequency error. Signals occurring on the 144.200 calling frequency appear at 144.1944. Other bands do not display this frequency error. These observations have been verified by a very precise RF signal generator. I verified that the 10 Mhz GPS reference is present and meets the Elecraft amplitude requirements. The tech mode menu "ref cal" asterisk is present and blinking, indicating that the radio is phase locked to the 10 Mhz reference. I went back through the installation manuals for the options mentioned and did not find any error. I'm concluding that I may have made an assembly error when installing the KSYN3a. Can some member of the Elecraft "brain trust" help me find and resolve this problem please?

I have an "ancient" Drake MN-2000 which is rated for 2000w PEP but I can tune it with 10w from my K3/10 with my linear off. Then I turn on my station control panel which enables PTT to the amp. Lately been using my AN-762 140w amp from CCI which I drive to about 120w with 5.6w. http://www.communication-concepts.com/140-watt/ I set the tuner on the 200w range to measure fwd and ref power. Sometimes I will touch up the tuner with the amp online as the amp and K3 are separated by 8-foot of coax and that appears to affect tuning (a little). But that only takes a couple seconds. Marking down cap settings for favorite frequencies is a good idea. But tuning a high-power tube amp at greatly lowered output does not work. Because the internal impedance of the tube shifts as anode current rises. My 8877 is about 5500-ohms at 1400w so you need to adjust it at working voltage and current. Input impedance changes radically from 100w to 1300w. So, unless you run high-power tube amps, you probably can get away with tuning the antenna on low power. Situation changes if you are using a sspa instead of tubes. 73, Ed - KL7UW At 10:16 AM 9/18/2015, ae4pb at carolinaheli.com wrote: >Forgive me in advance if this is a stupid question. > >Is there any reason you have to tune at full power?

Now if I turn my K3 to lets say the 10M band and try to play it also just shows "END". However re-booting my K3 and recording 5 seconds (for ex on 10M)....than playing it back actually has some of the 2M recording along with other previous recordings.

The Pitch is 650 Hz on the K3S. And the Mark for RTTY is the standard 2125 Hz. I've got a new 400 Hz filter on its way so I'll see what the problem is. I just hope it's not an RF board. I took ESD precautions very seriously while building it so, fingers crossed. 73, Jamie WB4YDL Sent from my iPad > On Sep 18, 2015, at 2:30 PM, James C.

My K3 is only about 8 months old, and because I live in the lightning capital of the world, has had only light usage. What I have experienced is that when the band or mode buttons are pushed, sometimes it erroneously invokes other functions. For example, pressing band down, the VFO B display shows "NO ATU" and does not switch bands. It's _not_ always the same error, it seems when it malfunctions, it is random. 73, K1AY (Chris) On Fri, Sep 18, 2015 at 9:28 PM, ayoshida wrote: > I especially notice annoying malfunction on buttons, Band/Up/Down/VOX/QSK, > Mode/Up/Down/ALT/TEST > and SUB button.

If you remove the front metal face, look closely at the whole area around the mod button. Mine had dirt get under a corner and gave me the same results your seeing. Elecraft sent me a replacement membrane, I removed the effected section, cleaned it thoroughly and installed a new piece and all is well. This was well over a year ago now and no further issues.

My K3 is only about 8 months old, and because I live in the lightning capital of the world, has had only light usage. What I have experienced is that when the band or mode buttons are pushed, sometimes it erroneously invokes other functions. For example, pressing band down, the VFO B display shows "NO ATU" and does not switch bands. It's _not_ always the same error, it seems when it malfunctions, it is random. 73, K1AY (Chris) On Fri, Sep 18, 2015 at 9:28 PM, ayoshida wrote: > I especially notice annoying malfunction on buttons, Band/Up/Down/VOX/QSK, > Mode/Up/Down/ALT/TEST > and SUB button.

So - to my shop I went. The box was a size match for the P3 with a PHONE plug installed. I used 1/8 and 1/4 plywoods for some of it and 1" pine for the bottom. I installed a Bose speaker found on eBay (very heavy magnet). The box was not filled with any deadening material, as it was constructed of wood. The back was sealed - with a single 1" hole on the rear. Carefully finished (lots of hand sanding, filling, and several coats of black stain and flat varnish) and carefully labeled, the design looked perfect on the desk with the K3-Line. Performance was great - best sounding external speaker I ever used. Didn't cost much either - but, many many hours invested in building it. Kind of makes the new speaker from Elecraft look much better than building one. Do I use my speaker now? No. I gave it away and now use Behringer MS40 powered speakers. No design match, much bigger and heavier, two stereo inputs, built-in equalizer, and better sounding. Cost is comparable with the new Elecraft speaker. AFX rag chew sounds super on them. It is all about choices.

Telonic/Berkeley model 8107S 0-69dB, DC-2.5GHz, rotary 2 stage step attenuator. Not sure what these sell for new, but I've seen them advertised for several hundred dollars in far worse condition than this one is. Telonic/Berkely apparently still makes this model. I used this one along with my SARK-110 to determine the before and after MDS at VLF frequencies when I did the KBPF3 VLF modifications prior to the boards becoming available with the modification already completed. The input and output connectors are SMA female and I'm including a pair of SMA to BNC screw on adapters plus 2 double shielded, teflon insulated cables with SMA males on each end and SMA female to type N male adapters. The connection between the two sections is made up of solid copper shielded sub-miniature hard line coax with SMA male connectors on each end from the factory. Cosmetically the device is in decent condition and my SARK-110 analyzer confirms that it's 50 ohms in and out so it hasn't been subjected to any damaging levels of RF power and the VSWR up through 270 MHz (the limits of the SARK-110) is 1:1 to a 50 ohm termination. Asking $120 shipped anywhere in the US. I'd rather not try to ship these internationally as the shipping/insurance would be pretty high, not to mention the VAT in some countries. I can't post pictures here but high resolution pix are available and will be emailed on request.

It is one of the major reasons the lists exists. I see from your second email that the asterisk is not being shown when the K3 keys. This indicates that the KPA500 is not getting the PTT signal. The KAT500 does not listen to the PTT signal, it only disconnects it when it is doing a tune cycle. So you really cannot rule out a bad cable. Take a good look at the AUXI/O cable to make sure none of the pins are bent.also, ohm out the cable to make sure all the pins that are supposed to be connected actually are. If the PTT pin is not touching, then that would be the problem. The fact that using a Phono-Phono cable from the K3 to the KPA is a bit troubling, make sure that cable is good also. Next check the KPA500?s menu settings to make sure that the INHIBIT signal is disabled. Shorting that input with the signal enabled in the KPA would also cause the KPA to not go into amplify mode. While you are investigating, make sure the K3 is actually asserting the PTT signal. If you don?t find the problem up to here, open the KPA?s top and check the 40 pin ribbon cable on the left side to make sure it is properly seated on both ends (IO board and Front Panel board.

I have a pair of K3 rigs on the desk. No trouble with one. On the other, Mark tone is sent higher than 2125. (It's high enough up that my 2d rig can't decode the TX signal. Maybe around 2600 Hz) The Space tone may be high too - my ear can't discriminate. (But in the X-Y scope pattern of the TX signal, as received on the 2d rig, the tones are at right angles - if that means anything...) Thinking it might be a TX AFC problem, I disconnected the computer. Same result. When I long-push PITCH, the rig speaker gives the 2125 HZ tone. But when I touch XMIT, the rig gives a different - higher - tone. (In contrast, with the other K3, both buttons yield the same tone - a tone which matches the 2125 Hz output by the problem rig when I press its PITCH button). I tried updating all firmware (e.g., from 5.10 to 5.35). But issue persists. Ideas?

Without that kind of help, I would still scratching my head. Here is where I stand: I have a work around by using the KPAK3AUX Cable from K3--> KAT500 -->KPA500 with the Key line inhibitor installed at the K3. I am also running a separate key line from the K3 Keyout jack to the KPA500 PA Key jack. (My first keyline cable had a broken shield, so I have replaced it) Everything seems to work this way, however still have the problem of either the KPAK3AUX cable which does check out ok, Pin 10 is straight thru, while pins 1,6,7, and 8 are not hooked up in the cable, verified with multimeter. The other possibility is that PTT Line of either the K3 or the KPA500 AUX Port is not working properly. I just have to figure out which end is at fault. I have tested Pin 10 at the K3 and when I key the rig I see movement on the multimeter , so I am thinking that Pin 10 at the K3 end is working ok. However I have been wrong before. I have tried 2 x KPAK3AUX Cables and get the same results with both cables so I think I can rule out a cable problem That really just leaves the KPA500 AUX port Pin 10 and inside the amp. I think I have pretty much covered all the area's of concern so I am going to do up a detailed report of what is the fault and what was done to verify things etc and talk to Elecraft on Monday.

It takes 3 steps. 1) Change your subscription to individual emails 2) In your email client create a folder named "Elecraft" or any other name you choose. 3) Also in your email client, create a filter that moves any email with [Elecraft] in the subject line to the Elecraft folder. Now you have you own personal "digest" in your email. You can quickly scan through it exercising the delete key for those posts that are not of interest, and you can easily reply to any one of them - Reply should go only to the sender, Reply All will go to the list and the sender, and Reply To List (if your email client has it) will reply only to the list. 73, Don W3FPR On 9/20/2015 8:33 AM, George via Elecraft wrote: > Four Elecraft Digests in one day is more than I can swallow.

It was originally designed for very slow circuits to end users when individual fetches were problematic. Decades later systems like Gmail handle that seamlessly and allow individual sorting of email to taste. With my smartphone and the Gmail app I can sort out mail I **don't** want to read, by visually scanning subject lines in just a few seconds. If there are thirty posts on the same subject and thread they come up as a single subject line, not thirty scattered around on separate lines. Then tap tap tap tap on unwanted subject lines to highlight them. Tap on the garbage can icon to send them to the folder that deletes them automatically after thirty days. The alternative is mail censorship or endless bickering about what and how much ought to be on the reflector. Having learned to use Gmail's filters, over time a personal collection of filters plus the Gmail web or smartphone app can deal with even a hundred Elecraft emails in a minute or two. That does not include the time to read, absorb, and respond to the email you have *chosen* to actually read. Email today is way better as a process than what was going on when digest mode was invented. To me anyway, it's mildly mystifying that anyone still uses digest mode. 73, Guy K2AV On Sunday, September 20, 2015, George via Elecraft > wrote: > Four Elecraft Digests in one day is more than I can swallow.

That allows the KAT500 to disable keying of the KPA500 during a TUNE operation. To sequentially test the operation of the KEYOUT lines and the cables, do the following checks in order - these checks can tell you the failure point. If you can relate that failure point to Elecraft support, you should be able to quickly resolve the problem. You should first verify the operation of the K3 KEYOUT with your ohmmeter. Set the K3 to TX TEST so no RF is produced, then with your ohmmeter probes connected between the center of the RCA KEYOUT jack, key the K3 - the ohmmeter should go to zero ohms. Do the same with pin 10 of the DE15 connector (KEYOUT-LP). If both those tests succeed, the K3 KEYOUT is working for both sources. If either check fails, you have a K3 problem with the KEYOUT signalling. Now to check the cables and KAT500 operation. The question to be answered is "At what point does the test fail?" That answer will identify the failure point. Set the KAT500 to AUTO. Plug the KPAK3AUX cable into the K3 DE15 ACC connector (without the keying interrupter) and make the same check between pins 10 and 12 at the far end of the cable. You should get the same zero ohms result - if not, the cable is faulty. You can also check the RCA cable in the same way - at the far end of the cable connector check between the center and shell of the RCA connector. Checking further, plug the KPAK3AUX cable into the KAT500 XCVR DE15 connector. Then measure the resistance between pins 10 and 12 of the AMP DE15 connector. It should go to zero when the K3 is keyed. Now do an ATU TUNE from the K3 - the resistance should still be high (perhaps infinite). Plug the RCA cable from the K3 KEYOUT jack into the upper PTT RLY jack and measure the resistance at the bottom one. Again, when the K3 is keyed, the resistance should go to zero, but when you do an ATU TUNE it should stay high. If those tests are good, remove the RCA cable from the KAT500 and continue the check by plugging the 2nd KPAK3AUX cable into the AMP connector on the KAT500. Check between pins 10 and 12 at the far end of the cable. Then re-install the KEYLINE INTERRUPTER at the K3 and plug in the RCA cable from the K3 to KAT500 plus the RCA cable that will go between the KAT500 and the KPA500 and make the same checks at the end of the cable that would plug into the KPA500, checking that cable. If you got this far in the testing with no failure, the operation of the K3, KAT500 and the cables has been verified for both the K3 KEYOUT signal lines. The only thing left is the KPA500 inputs. Leave the KEYLINE INTERRUPTER in place and connect the KPAK3AUX cable from the KAT500 to the KPA500 and also connect the RCA cable from the KAT500 to the KPA500 PA KEY jack. The KPA500 should go into transmit when the K3 is keyed, but not during an ATU TUNE. Now remove the KEYLINE INTERRUPTER and the 2 RCA cables and repeat the test. The KPA500 should behave as above if its KEYIN-LP input is working correctly. If you have no devices (such as the STEPPIR controller, band decoder, etc.) that must listen to the K3 ACC signals, leave the KEYLINE INTERRUPTER out as well as the RCA cables and all should be working - put the KAT500 back into MAN after retraining the KAT500 to the antenna that was selected for the test. If you DO have something that needs to listen to the K3 PTT, then put the KEYLINE INTERRUPTER in place (at the end of the KPAK3AUX cable, not directly on the K3 ACC connector) and both RCA cables. You will be using the "Y" cable at the K3 ACC connector to be able to connect the K3 ACC signals to the external device. In other words, do NOT use the KPAK3 AUX cable *without* the KEYLINE INTERRUPTER along with the RCA cables. 73, Don W3FPR On 9/20/2015 4:25 AM, Mike VE3YF wrote: > > I have a work around by using the KPAK3AUX Cable from K3--> KAT500 > -->KPA500 with the Key line inhibitor installed at the K3.

Some work well, some don't, and wiring is an issue -- as are such subtleties as bias vs. no bias, etc. I'm surprised you say "Microphones, seriously?"; but there are likely topics where I could say "xyz, seriously?" and get a similar response.

Prior to purchase I was told that the K3S would NOT solve the high noise levels at my QTH and that it wouldn't affect my ability to hear. The oscillator arrived Saturday afternoon, was installed and I did the low power calibrations. I connected an antenna and the noise floor is indeed the same as before with one HUGE exception. I can actually hear and clearly receive signals MUCH BETTER than I could before. Now it's just a matter of learning to leverage the radio's strengths and follow all menus down their respective rabbit holes. I'm finding the DSP to have many different settings and have yet to learn what's configurable. The depth and ability out of the box for this radio is well worth the cost and is definitely valuable.

The rules work if the sender remembers to include the radio or whatever (e.g., [K3], [KX3], etc.) in the subject line. I have that rule at the top of my Outlook rules so it's processed on incoming emails first. 73, Jim N7US -----Original Message----- George, Yes, I believe there is a 'better way'. It takes 3 steps. 1) Change your subscription to individual emails 2) In your email client create a folder named "Elecraft" or any other name you choose. 3) Also in your email client, create a filter that moves any email with [Elecraft] in the subject line to the Elecraft folder. Now you have you own personal "digest" in your email. You can quickly scan through it exercising the delete key for those posts that are not of interest, and you can easily reply to any one of them - Reply should go only to the sender, Reply All will go to the list and the sender, and Reply To List (if your email client has it) will reply only to the list. 73, Don W3FPR From KX3 at ColdRocksHotBrooms.com Sun Sep 20 11:47:47 2015 From: KX3 at ColdRocksHotBrooms.com (Lynn W.

The technique is kind of like the spam filter in Thunderbird. You start by tagging a message or two for each topic/folder, and then you classify when it gets it wrong. After a few days, the sorting becomes quite accurate, and you rarely have to touch it. I don't use it currently because quite frankly, in my opinion, this list is a little bit slow, and the traffic is easily managed.

Sure. Stop using the digest -- it only makes things worse. Instead, use email software that allows you to set up filters to sort all the emails from a given reflector into its own mailbox. Now, you can quickly glance at each to see of it interests you and use your delete key liberally when it does not. I use Thunderbird, which is free and works really well. 73, Jim K9YC From xdavid at cis-broadband.com Sun Sep 20 12:54:42 2015 From: xdavid at cis-broadband.com (David Gilbert) Date: Sun, 20 Sep 2015 09:54:42 -0700 Subject: [Elecraft] Four Elecraft Digests in one day In-Reply-To: <2f83fd.7a035af.4330019a@aol.com> References: <2f83fd.7a035af.4330019a@aol.com> Message-ID: <55FEE4D2.1000407@cis-broadband.com> Sure, it's easy ... just don't use the digests.

Connect the red wire to the ring of the jack, the green wire to the tip, and the black wire to the shell. If this is only a temporary measure, get a DE-9 male connector in addition to the jack and make up an adapter. The ring of the jack connects to pin 2 of the DE-9, the tip to pin 3 and the shell to pin 5. Plug the existing DE-9 female into your male adapter and plug the KUSB into the stereo jack. 73, Don W3FPR On 9/20/2015 12:19 AM, Robin Bayer wrote: > After computer upgrade, my Serial board no longer functions with my K2. > > Would it be possible to build an adapter using my KXUSB to the KIO2 special > cable on the K2? > From davidahrendts at me.com Sun Sep 20 17:14:45 2015 From: davidahrendts at me.com (David Ahrendts) Date: Sun, 20 Sep 2015 14:14:45 -0700 Subject: [Elecraft] K3S + FLDIGI + Mac Mini Message-ID: <51C4E5A3-8ED1-4656-B16F-AFCBA8D21CAC@me.com> Anyone configured with the K3S, FLDIGI and a Mac device?

Answered my own question moments after posting. And I am in awe. With ONE USB cable on the K3S, you have rig control, audio in and audio out. Short answers: 1) In FLDIGI config, Hamlib, find your port and initialize it. That?s rig control. 2) In FLDIGI config, Audio, select PortAudio, USB Audio Codec for both Capture and Playback. 3) Select FLDIGI mode PKTUSB which moves the K3S to DATA mode. Otherwise it likes to default to USB. 4) On the K3S, MIC control becomes Line level and mine likes to be around 6 before tripping too much ALC. The P3 showing a clean PSK31 signal. Sweet. Now, my Mac Mini is a beta tester for Apple El Capitan, and version 10.11 Beta (15A278b) is a little buggy with FLDIGI. Many screen freezes which I?m sure will be ironed out in time. There was this cautionary issued on 9/11: http://www.machamradio.com/blog/2015/9/10-fldigi-and-upgrading-to-os-x-1011-el-capitan Thanks, as always. Happy to answer any question off list also.

I'm on about 18 other lists so if all e-mails arrived individually the sorting thru would be horrendous. With the digest I can reply to any comments on the list. Only problem is sometimes an topic get moderated before I receive the digest so I cannot comment or that I do not get the moderation in the digest because it will be in the next one several hours later (after I already transgressed by commenting).

Thanks for all the responses and good advice. Much appreciated. I can see there's pros and cons to the various suggestions. I opened the box this weekend and found only two visible effects: 1) There is a slight discoloration of one portion of the traces that carry the current to the 100W PA interface. This is on the main RF board. 2) The encapsulation of the 5 milliohm current sense resistor on KPIO3 PA interface had shattered. It must have had ~100 Amps through it! Amazingly it survived as a resistor, though it's dropped to 4.3 milliohms now. So that wouldn't have stopped the PA working or explain the over-current warning. The sense amplifier itself is surface mount so that's beyond my skill level. There is no visible damage on the power amp card itself, I tried to check some of the diodes and inductors etc. in situ, - but nothing obvious. I can't find up-to-date schematics for the KPA3A, which makes it difficult to debug further. Based on the older KPA3 schematics, I assume there's a reverse shunt diode somewhere on the board. I see the circuit breaker & diode are positioned after the current sense circuit rather than before, which seems odd. Anyhow, at this point I'm giving up. I'll contact Elecraft and see if they're willing to look at it. Hopefully it won't cost an arm and a leg. I'm certainly very chastened by the experience. It won't happen again! Thanks again for the comments and advice. 73 Roger KK6RW/G3WEW On Wed, Sep 16, 2015 at 2:10 PM, Mel Farrer via Elecraft < elecraft at mailman.qth.net> wrote: > Here is where I got my color coded heavy wire.

I then discovered that they are local to the Seattle area (my QTH is Kirkland, in the Seattle region). In fact, they are a couple of doors down from the Woodcraft Store in south Seattle. Since my woodworking hobby regularly takes me to Woodcraft I dropped by their location on one of my trips. But, it is not a retail office ? I think they do almost all of their interaction via the web. But, expensive! I costed out a small cabinet fitting to the 2-meter amp and it was about $100 or so. They are set up to do dozens or 100s of copies from a single design. They do sell raw material though in good sizes for making your own box and this is what led me into looking at the 90-degree corner brackets that Elecraft uses but charges quite a bit for them. 73, phil, K7PEH > On Sep 21, 2015, at 4:40 PM, Kevin Stover wrote: > > I think I read in one of the higher power amps write up that he uses a company called http://www.frontpanelexpress.com/ to make his cabinets.

Is this loss of mode necessary or can it be fixed? (It only happens if I power up the P3 while the serial port is disconnected.

I then discovered that they are local to the Seattle area (my QTH is Kirkland, in the Seattle region). In fact, they are a couple of doors down from the Woodcraft Store in south Seattle. Since my woodworking hobby regularly takes me to Woodcraft I dropped by their location on one of my trips. But, it is not a retail office ? I think they do almost all of their interaction via the web. But, expensive! I costed out a small cabinet fitting to the 2-meter amp and it was about $100 or so. They are set up to do dozens or 100s of copies from a single design. They do sell raw material though in good sizes for making your own box and this is what led me into looking at the 90-degree corner brackets that Elecraft uses but charges quite a bit for them. 73, phil, K7PEH > On Sep 21, 2015, at 4:40 PM, Kevin Stover wrote: > > I think I read in one of the higher power amps write up that he uses a company called http://www.frontpanelexpress.com/ to make his cabinets.

I had already considered offering the W6PQL 80w amp fully assembled with RF output bar meter. The kit comes with attenuator that will accept up to 10w drive or a low as 50mw. For the KX3 I suggest 1-to-2w as a good drive level. I didn't finish my cost analysis but I can state cost will be approximately $100 over parts for an amp assembled by "Kits made by KL7UW". The amp will include a fan-cooled 1-inch heatsink auto-controlled by thermistor. I cannot start assembly until November as I am totally booked until then building Down East Microwave Transverters (five in que at present). I will work up the complete costs and will have that on my website: http://www.kl7uw.com/kits.htm I currently offer 90-day warrantee on my workmanship building DEMI kits. If interested contact me off the list and I will add you to my info list. Not taking orders until I have the complete costs analyzed and a price set.

I already have a KX3 with transverter and SSPA. I have an old BNOS 3W to 100 W amplifier in my cupboard, should I ever wish to go portable with the KX3 ( though I have not bought the internal 2m transverter yet, as I may instead get a 4m transverter to cover that band). Can I ask you a few questions? What would be your intended use for this amplifier? 1. Out portable with the KX3 (where you have a small generator or large battery)? Ruggedness is more important than looks here. 2. Local FM simplex at home where 3W barefoot from the KX3 might not be quite enough and you want a nice looking box to match the rest of the lineup? 3. Casual weak signal work from home on SSB CW WSJT? 4. As a driver for a legal limit triode tube amplifier for Real DX and contest work? These are the main uses I could see, and you have to ask how many people might be interested in those. ( You did ask the question and I think you will find the answer is very few in real numbers). For item 4, more and more the legal limit tube amplifier is being replaced by the LDMOS SSPA which requires only 3W or so to drive it to a kW out, so the driver amplifier is no longer required. For Item 3, there are so many DC- Light multimode multiband radios out there that cover 2m with 50 to 100 W output now that satisfy the casual user, the real contester and DXer will use a K3 and high quality transverter and tube or LDMOS SSPA nowadays. I just can't see the numbers being anywhere near high enough for Elecraft to be able to make an intermediate power VHF amplifier at what would be a price that most would even think about paying. If in any doubt see how much the newly introduced matching Elecraft speakers are, and that is for a product that is going to be much more popular. As others have said, the alternative is to build a W6PQL amplifier kit, into an Elecraft speaker box if necessary ;-) 73 David Anderson GM4JJJ > On 21 Sep 2015, at 22:58, Phil Hystad wrote: > > I am curious ? how much interest is there in a 2-meter, solid-state, amplifier from Elecraft that could be used with either the KX3 or the K3. > > I own a KX3 with the 2-meter option and I have considered buying a 2-meter amplifier in the 35 to 90 watt power range (or, something close to that).

Your experience would be quite different west of the Mississippi, where population density is much less, and with much greater distances between population centers. That's why, for example, the FCC licenses 10 dB greater TX power west of the MS river. Higher TX power also helps for moonbounce and meteor scatter. 73, Jim K9YC From k2vco.vic at gmail.com Tue Sep 22 13:22:57 2015 From: k2vco.vic at gmail.com (Vic Rosenthal 4X6GP/K2VCO) Date: Tue, 22 Sep 2015 20:22:57 +0300 Subject: [Elecraft] Elecraft SP3 External Speaker - New Thread In-Reply-To: References: Message-ID: <56018E71.9010401@gmail.com> Will stainless screws be an option or standard?

While I do have a brake and no problem crafting cases I will tell you how I would do it without major tools. 1. Do a drawing of the case with sizes and flanges laid out piece by piece; top, bottom, sides, ends, etc. 2. Locate the nearest Metal Supermarket. I use them as they are close and reasonable and I know them and their stock. They will cut your metal pieces to size very cheaply. Often free. 3. Contact them for a quote and order. They may mail your order, I do not know. There are other places who do the same type business; small orders with cutting. 4. Cut?2 hardwood blocks that just fits inside the lines of the front and rear panels. They should be smaller by the thickness of the metal material plus a smidgeon. 5. Carefully fit the blocks within the lines of the panel you are bending and clamp in a vice. The blocks should be aligned as well as with in the panel lines; Use double sided?tape if necessary. 6. Use another hardwood block as a "push block" and gently push and hammer against the flange all along its length until it is bent 90 deg. bending only a small part of the angle at a time. 7. The blocks are also useful when drilling the holes. Some may prefer to drill first but that makes hole alignment very difficult.

Yes, since you already have the rear panel with the ANT3 hole, resume about the middle of page 12 where it begins with "Locate the TMP cable ..." In order to tighten the BNC connector, you may find it easier to loosen the panel and tilt it back, but if you can get whichever tool you are using to tighten the nut on securely without removing the panel, that is OK too. Make certain the BNC jack is adequately tight. 73, Don W3FPR On 9/22/2015 12:41 PM, Carl J?n Denbow wrote: > OK, Don, I've run into a little confusion: the bottom of page 11 of > the K144XV instructions has details about installing a new back panel > with an ANT 3 hole.

The fact the gentleman had no address information on QRZ certainly could be as you say or as one other person suggested, the call sign was highjacked. I rarely sell except when updating my station and always use PayPal. If the buyer doesn't like PayPal then there is no sale. I ship when PayPal has the funds in hand, and I follow up with the tracking information to PayPal as proof of shipment. I also tell my buyer he has 7 days to return the item to me in original condition for a full refund if he/she is not completely satisfied. So far it has all worked for me and I have not suffered any loss in the few internet sales I have made. Jim, W4ATK On 9/22/2015 3:19 PM, David Gilbert wrote: > > Not so.

Based on that I have posted information at: http://www.kl7uw.com/kits.htm The amplifier will use a 1.375x5.375x8 inch heat sink with a 120mm fan. Fan will be thermistor controlled. The enclosure chosen is the Hammond 1590D 4.7x7.4 inch diecast aluminum box. It will be available in natural aluminum or painted a light flat gray. A ten-segment LED RF power indicator will be included. Otherwise is as described on the W6PQL website (link from my website). It will be offered as a partial kit (all surface-mount components pre-installed but all thru-hole left to the customer). Price $284.00 + $18 flat-rate shipping & insurance Also available fully assembled and tested for $354 + $18 flat-rate shipping & insurance Optional N female connectors for additional $5.00. All prices in US funds and subject to change without notice and only apply in the USA. I will ship international but shipping will be more. NO ORDERS accepted until November, 2015. E-mail me if you want to be put on a pre-order waiting list. PayPal will be preferred method of payment.

Keep antennas separate as far apart as possible (this is just good multi-station practice) 2. Set up all KX3s to have their isolation amplifiers turned on (MENU:RX ISO). This keeps the local oscillators of different radios from interfering with each others' receive if they happen to be tuned to exactly the same frequency. 73, Wayne On Sep 22, 2015, at 12:38 PM, Dan Atchison via Elecraft wrote: > Has anyone used a KX3 in a multi-two environment?

I open my owners manual, page 20, which says I can use that connection for control and PTT. I'm already using the USB for control so will just use it for PTT. I have a USB to serial adapter so I install it, plug in the RJ47 connector to the rig, mate the DB 9 connectors and immediately smell burning components, Quickly disconnect the DB9. I was previously using this serial adapter successfully on a YAESU FT-897D before I sold the rig to get the K3S. So now the questions: 1. Why did this apparently experience an issue? I see nothing in the manual to indicate this requires anything but a standard connection. 2. How much damage has been done to my brand new k3S using the supplied Elecraft cable and a known good previously good USB to Serial cable (MFJ I believe). I'm heartsick.

If so, that is a "No-no". RS-232 (whether from the internal K3 USB to serial adapter or from an external adapter) is a one to one, point to point protocol. It must have *only* one driver on the signal lines. If you connected both at once, you had two drivers on the signal lines, and those two drivers would "fight with one another", possibly causing damage. When one driver is trying to send a mark, the other trying to send a space, those two signals are of opposite polarity and can cause damage to one another. So whether you damaged your external USB to serial adapter or if you damaged the internal USB to serial adapter in the K3S is indeterminate - damage could have been done to both. 73, Don W3FPR On 9/22/2015 10:42 PM, ae4pb at carolinaheli.com wrote: > So my new K3S is running well and I'm setting up my software and see that it > can do digital modes and control PTT using a comm port.

Message-ID: <1442984533699-7608175.post@n2.nabble.com> Greetings, I'm having a problem with my KX3 that I have not been able to resolve. Equipment: KX3 S/N 7210, FW 02.25 Problem: While performing a tx gain calibration using the KX3 utility software (rev 1.14.4.11), it failed when trying to cal 52MHz. This was because the VSWR on that band was 1.8:1 (dummy load directly connected - no cable, ATU bypassed). I checked the load (Narda 40W D.C. -> 12GHz) and it checked OK using another rig (TS480) - flat across the (6M) band as you would expect. I was orginally having issues when the voltage would drop below threshold causing the power level setting to change and that would result in no power out (PSK31). TX gain cal fixed that on the problem band (40 meters) and 160->10M is fine. Honestly, I don't think I ever tried 6 meters - no interest at the time - so this problem could have been there since day one - but the factory inspection test (the inital TX gain cal?) should have caught it, so not sure when or how this would have occured. Thinking that perhaps this was a config bit gone astray, I loaded a config file from February (about 2 months after I got the radio). Still had the 6M SWR issue, but the power level was working OK....apparently that got pooched some time after that config backup. The config backup I did just before the TX level cal restored the power level problem - so that is repeatable - and fixed. Backups are a wonderful thing. The 6M VSWR problem appears to be unrelated - just surfaced during the TX gain cal. If I enable the ATU, I can get a 1:1 match to the dummy load, and I get 10W out (KX3 meter). So...how to proceed? Seems like maybe a band switch/output tuning network problem? Although, for 6M it is a straight thru connection (via K8). Comments appreciated. On a positive note, great radio!...as I'm sure you have heard at least 7210 times;) I'm am having alot of fun with this radio. It's amazing what you can do on 40M with 3 watts and a dipole supended 10ft above salt water on a wood pier railing (long story) - 40dB C/N at 125Mi NVIS path.

I am not sure what you mean by "I'm already using the USB for control so will just use it for PTT. " You can certainly use USB for audio and RS232 for serial control. If you use RS232 for serial control, you need to set up the menu for the data rate. You must also use RS232 for RTS and DTR in that case. If you set up for USB for serial control,then you must use RTS and DTR over USB as well. I have plugged in USB<->RS232 cables between my computer and the KIO3B using the supplied RJ-45 <-> DE-9 cable and it worked fine. I have also done this using USB for audio. No smoke ever escaped during all of this testing and use. I cannot diagnose what may have failed or why, but it sounds like the computer system may have a different power ground return than the radio system and there may have been current flowing though the RS232/USB connection as a result. Hooking a serial port to the supplied serial port cable with the menu selecting RS232 should cause no problems, and using USB with the menu selecting USB should cause no problems. I have had things hooked up and had the menu in the incorrect selection (RS232 but only USB physically connected, or USB with only RS232 physically connected) with no physical damage, though of course the rig did not communicate with the application under those circumstances. 73, Lyle KK7P > So my new K3S is running well and I'm setting up my software and see that it > can do digital modes and control PTT using a comm port.

I owned one of the "brown" B1016, which is the older version, and it didn't output 80w anymore but did a good job at about 65w. The preamps in these VHF amps were never low-noise preamps but extra gain did help some of the older VHF radios which also did not have low-noise front ends. They were designed with mobile operation in mind where local noise is sometimes high or there is lots of adjacent high level signals which drive sensitive preamps into overload. But if you are on a budget the used amplifier market is a good source for a VHF amp (but there is more risk of getting a "bum" unit, also). I've a pretty good record acquiring used amps. Most of the "bums" were from my local flea market and not from e-bay or from e-mail lists. I currently have two RFC 2-30 which make very nice 25-30w companion for the KX3 (small) and are linear for SSB. I have a RFC 2-317 30w-in/170w 2m amp in my home station. Also have Mirage A1015G 6m 150w linear. A few more on my repair shelf which I will get around to fixing someday (probably to sell). I was given an old MOT 60w FM amp which drives very nice with 1w from my KX3 for use on repeaters and simplex FM. I recently bought a PR6-10 for my K3 from a ham upgrading to the KVX3B and it works very nice (I copied 6m-eme signals with it). I also have a ARR P50VDG preamp which I will install on my 6m tower for serious eme work. I have low-noise preamps on 222, 432, 900, 1296, and 2400 MHz so do not rely on internal preamps in my transmit amplifiers. 73, Ed - KL7UW ------- From: Ray W2RS via Elecraft To: elecraft at mailman.qth.net Subject: [Elecraft] 2-meter amp Message-ID: <4614b.437bb4a6.433308de at aol.com> Content-Type: text/plain; charset="US-ASCII" I'm using an old (pre-MFJ) Mirage B1016. 10W in = 160W out.

I use to have access to a brake at work (retired five years). I also used to buy some really nice enclosures from a K3 ham in the east who is now sk (used in my 2m-8877 and CCI HF amps). I have resorted to the wood block method but the results were not good enough to sell someone. So either, I use angle stock for corners on HB projects or buy commercial enclosures. Bud is still in business for a utilitarian box. Mouser offers a selection which I got an enclosure for my 30w 1296 PA project. But costs are high when you add shipping. Thus, I chose to use the Hammond box for my production amp. It costs $20.29 from Mouser. Can't make any that cheap after material costs, tooling costs, and labor. BTW there are more than four holes in the 80w amplifier project. Four to attach heat sink to chassis; eight for coax connectors; four to attach pc board; two for 80w RF module; four for fan attachment; two to attach LED power indicator. Most will require tapping 4-40 or 6-32 threads into the heat sink. Hammond box cover already has tapped holes for attachment. Probably a couple hours metal work labor in each amp without having to make the enclosure. 73, Ed - KL7UW Date: Tue, 22 Sep 2015 18:58:44 -0700 From: "Richard W.

If so, that is a "No-no". RS-232 (whether from the internal K3 USB to serial adapter or from an external adapter) is a one to one, point to point protocol. It must have *only* one driver on the signal lines. If you connected both at once, you had two drivers on the signal lines, and those two drivers would "fight with one another", possibly causing damage. When one driver is trying to send a mark, the other trying to send a space, those two signals are of opposite polarity and can cause damage to one another. So whether you damaged your external USB to serial adapter or if you damaged the internal USB to serial adapter in the K3S is indeterminate - damage could have been done to both. 73, Don W3FPR On 9/22/2015 10:42 PM, ae4pb at carolinaheli.com wrote: > So my new K3S is running well and I'm setting up my software and see > that it can do digital modes and control PTT using a comm port.

I know that will not work, and because one driver can be trying to drive a positive voltage on the signal at the same time another driver is driving with a negative voltage. Not only will that not work, but the drivers can damage each other. But then I do not have detailed schematics. Lyle has responded that he has connected both the USB and an RS-232 adapter with no problems (he should know since he is one of the K3S designers), so the implementation in the K3S apparently has designed in protection for that situation.

I know that will not work, and because one driver can be trying to drive a positive voltage on the signal at the same time another driver is driving with a negative voltage. Not only will that not work, but the drivers can damage each other. But then I do not have detailed schematics. Lyle has responded that he has connected both the USB and an RS-232 adapter with no problems (he should know since he is one of the K3S designers), so the implementation in the K3S apparently has designed in protection for that situation.

Nothing will be damaged. The input signal group TO the radio from the outside world (RTS, DTR, serial data) are physically switched as a group between the RS232 buffer chip and the USB<-> serial chip. In USB mode, data to the radio, along with RTS and DTR, will only be recognized from the USB port. Data FROM the radio will be available on both the USB port and the RS232 port. This allows you to use USB to a computer, for example, while having an antenna tuner or SteppIR antenna or other external devices "listen" to the radio data. In the RS232 mode, all three signals are switched as a group to the RS232 buffers. Again, serial date FROM the radio is simultaneously present on the USB and RS232 ports, though in this case the data on the USB port will only be meaningful if the RS232 port is set to 38,400 bps because the internal USB<->serial chip is set to communicate internally for 38,400 bps at all times. The USB mode or RS2323 mode are selected from the RS232 menu. If a data rate is displayed (4800, 9600, 19200 or 38400) then the RS232 mode is in effect. If the display is "USb" then the USB mode is selected. Similarly, LINE OUT audio (from the radio) is always sent to both the USB port AND the analog LINE OUT jack on the rear of the radio. if nothing is plugged into the LINE IN jack, then audio in LINE mode will be taken from the USB port. If a plug is detected at the LIEN IN analog jack, then USB audio will be ignored and audio will be expected from the analog LINE IN jack. I'm sorry if the documentation in the manual was not clear on these points. 73, Lyle KK7P > What I'm trying to do: > 1. USB for audio and serial control. > 2. RS232 for PTT keying.

I maintain the station for an elderly friend who prefers CW, and often operates at about 40 wpm. A while back he told me that his "E"s were too short, and hoped I could change the timing or weighting, or whatever to "fix them". When I hear him on the air, I thought they sounded perfect... he swears that they used to be, but no longer are. I went over and verified that the weight setting on his K3 was set as mine was, and that his microHAM keyer was set as mine was as well. He still said that the letter "E" was way too short. Today I went over to his QTH again. I sent some CW at 40 wpm and agreed with him that the letter "E" seemed short... I listened carefully at a variety of speeds, and down around 20 or 30 wpm all sounded good to both of us. I had no instruments to verify what I was hearing, but it 'seemed' to me that up around 40 wpm the leading dit of any character was a bit short. I admit, I am not a 40 wpm guy, but that is how it sounded to me. I then went into the next room, where he has a different station setup, where I selected NO antenna, turned the RF gain way down, and tuned that rig to the same freq as his K3. I then had him transmit at 0.1 watt from the K3. To my ear the CW I was hearing on the other radio was perfect. We then traded places, and I transmitted while he listened. I transmitted from 40 up to 50 wpm, and he agreed that the CW coming from the K3 was "perfect"... but at 40 wpm the monitor signal from the K3 does not sound perfect. He said that it did sound perfect until a couple of months ago. Assuming that it, in fact, does now sound different that when I first setup the station for him, I have no idea what may have changed, or what to do about it. As I indicated, I cannot quantify the change, but I do believe that it is different. I am now home and my K3, with all the keying settings the same as his, and with my microHAM keyer set the same as his, sounds "perfect" at 40 wpm. I started to wonder if a component in the monitor circuit may have changed value, resulting in a truncation of the sound of that first dit. I want to help my friend, but I have NO idea what to try next.

The Elecraft community is the best. NR4C had the secret answer. VFO LINK in the Config menu was "ON." Toggling it OFF unlinked the A/B VFO. As Bill points out, previous FW revisions could lock/unlock the two VFOs by holding the SUB button. That's been removed in the current FW. I remember locking them in the past, but no can do directly anymore. A macro is the only way to automate the linkage.

The installation went fine and the radio has been used extensively all year. Yesterday, I updated the FW from 5.01 to 5.35 along with the later DSP and FP versions. I then restored a K3 Configuration I had saved prior to the KSYN3A installation. Now the radio won't receive or transmit and I suspect this is due to it thinking the old KSYN3 boards are installed.

And we are not capital intensive, which insulates us from some of the tax costs in CA associated with larger industries.

The wage and facility cost increases here have tracked those in our type of industry outside the state. Our engineering team is located both here at HQ and up and down the west coast from Washington state to Arizona, which keeps those costs in control too.

In fact I don't know of any other area that enjoys high employment rates in high paying positions, lower cost of living/taxes, lower crime. Why would I want to move somewhere with higher taxes, crime, and unemployment? If I could find the same or better standard of living elsewhere that also afforded high employment and low crime I'd definitely consider it. CA is an excellent state to visit and I've worked for several companies based there (including the US Navy). San Diego, LA. And the Long Beach are all nice areas but expensive to live with higher crime rates. I don't know much about Mo. as it's never mentioned in discussions about technology or high paying jobs. In fact the only time I recall hearing about Mo. was during the riots in Ferguson. 1. Standard of living is not 1:1 with cost of living. 2. Anything that increases the cost of doing business has the net effect of increasing the cost of goods and services. 3. I see no reason why you assume and imply that my standard of living is low. You obviously know nothing about me or the area in which I live. 4. If the job market were to dramatically change in a negative direction I would re-locate. It's a matter of record that families from all over the country ARE moving to my State/area due to higher standards of living with lower costs of living. Kent, at the end of the day the goal of a business is to make money. When the cost of business rises then the company makes decisions to cut costs or raise prices. In this case Elecraft has decided to raise prices. I want to support them because they are US based and I appreciate the value they bring up to a point. For me personally I paid the premium for the radio because I believe in the company. Is it wrong for me to want the company to survive and ask if they considered moving the company to lower their costs of doing business because they may be struggling ? 2nd major jump in prices in less than a year? If you were attempting to insult me then I apologize for taking your question seriously. If your attempt was to insult then my answer to you is: "Bless your heart".

Inflation is caused by devaluation of our currency and anything that increases the costs of doing business without adding value to the good or service being offered. Free enterprise on the other hand tends to lower costs due to increased competition in the marketplace. Taxes, regulatory compliance, and other costs PREVENT companies from entering the marketplace or at least slow them down. Remember that business are not charities. They exist to make a profit. If the profits are too low to be worth-while then why enter the market? The strength Elecraft brings is customer loyalty. -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Rose Sent: Thursday, September 24, 2015 12:08 PM Cc: Elecraft Reflector Subject: [Elecraft] OT: Price Increase Alert for mid October Inflation is an absolutely guaranteed byproduct of our free enterprise system! 73!

The switchbox uses XLR connectors so I can use the Heil K3 "proper" cables to each rig. I bought a regular XLR extension cable for the mic to swithbox. Well, I used a DPDT switch to switch both pins 1 and 2. Hum. Then I used a 3PDT switch for switching all pins, 1, 2, 3. Hum. Notice both Heil cables have outer shell at rig tied to mic low. Don't wanna cut this wire, or should I? Now all this said, I am powering each rig from a separate power supply. My question is, before I go to the expense of purchasing a power supply large enough to power box rigs at the same time, will this eliminate my hum or ground loop?

The long answer is that the video chip we are using on the SVGA accessory board limits us to how many "video layers" we can combine to produce the video image.

One of the other readers of this list sent me a pointer to Unicomp , which sells keyboards with real tactile feedback. I fired off an order for a Buckling Spring USB keyboard with a Macintosh layout. Slow USPS delivery took about a week, but the resulting keyboard is very nice. I get fewer errors copying W1AW code practice at 13 and 15 WPM (my current speed limit). The general feel is very nice.

I use a variant of MMTTY that is designed to interface with DXBase, my logging program. MMTTY would be setup the same. I use AFSK A and low tones, 915 Hz, and set up MMTTY accordingly. Make sure whatever decoder you use is set to TX and RX using whatever tones you set the K3 to. Turn off the dual filter, it's mostly useless and set your RX bandwidth to 400 Hz. Some folks want to use narrower BW, but there is little, if anything, to be gained by this. Worry about decoding the DX station. You don't care what the other guys are sending. and trying to tune them to decode them is unnecessary. Here is where a P3 or other bandscope shines over a second RX, all IMHO of course. Wes N7WS 242 DXCC countries on RTTY all worked with a K3.

Using FSK I believe you will have to assert PTT via the 15 pin ACC connector? I'm using an adapter made and sold by W1AN. It connects to the K3S ACC port and a standard COM cable to the PC. I have RTTY FSK working successfully with Winwarbler and a K3S. If you don't get yours working contact me directly via email and I'll send you screen shots of my Winwarbler settings.

For RTTY, you would normally be in AFSK A and then you could activate the dual tone filter. I believe most use MMTTY for RTTY, but HRD/DM780, Fldigi and other waterfall oriented software can work as well. In AFSK A (or FSK D) the K3 is in LSB (normal for RTTY) unless you activate REV, and the K3 dial frequency is the mark frequency. Make certain that the mark frequency and rate in the K3 menu agree with your software application settings. Other soundcard data modes normally use DATA A where USB is the normal sideband. 73, Don W3FPR On 9/24/2015 12:35 PM, ae4pb at carolinaheli.com wrote: > I was trying to work K3P on 80m RTTY last night (new mode for me) and was > struggling to understand the owner's manual.

In AFSK A (or FSK D) the K3 is in LSB (normal for RTTY) unless you activate REV, and the K3 dial frequency is the mark frequency. Make certain that the mark frequency and rate in the K3 menu agree with your software application settings. Other soundcard data modes normally use DATA A where USB is the normal sideband. 73, Don W3FPR On 9/24/2015 12:35 PM, ae4pb at carolinaheli.com wrote: > I was trying to work K3P on 80m RTTY last night (new mode for me) and > was struggling to understand the owner's manual.

I do find the value of THR is somewhat dependent on RF Gain. Thus more atmospheric noise / static bursts the higher value for THR. In this case reducing RF Gain helps. This evening the RF Gain, hr on 80M, is setting between the 1 o'clock and 2 o'clock position or the first dot to the right of the 12 o'clock position. And yes do use the SPOT function to accurately tune the receiver to the incoming signal. Also I use Fast ACG for CW. As to WIDTH I use 0.50 and SHIFT at 0.70 for CW. With this and the above, i get very few T T ** E E E * E in the display. 73 Bob, K4TAX K3S s/n 10,163 On 9/24/2015 6:30 PM, Bill Conkling wrote: > My experience with CW decode is: > > Try setting the THR to 2.

I am probably 90% CW, ~3% SSB [Sweepstakes, NAQP's, and RAC's], and the rest RTTY. This is probably going to touch off a storm on the list, but here goes: I run the RF gain full clockwise, always, I don't even know if the knob moves, never tried, never understood the "ride the RF gain argument." The K3's AGC is superb and far better than anything I can do. Admittedly, it is highly tailorable [maybe a tad too many settings], but once I got it where I liked it, I haven't touched it in several years [S/N 642 here]. True even when I had KF6T running 1.5 KW 1.7 km from me. I have the "stock" 2.7 KHz [I think] and a 500 Hz roofing filters. I could cuddle up to within 1 KHz of Jack and not hear him. Preamp is on for 21 MHz and above, off below. Attenuator is off for 7 MHz and above, on for 5, 3.5, and 1.8 MHz. That configuration depends some on your ambient noise levels, mine were moderate until we just moved, now they're fairly low. I copy CW the old fashioned way, but I have tried the decoder out of curiosity. Does well on moderately good signals with reasonable sending habits. A SNR of about 4 S-units seems to work fine. Gets a little sketchy with occasional errors [usually in key up periods] below that, and pretty much fails if the SNR is around 1 S-unit or less. I can still copy the signal fine at those levels. I can't remember what I used for THRESHOLD, but as I remember at one number nothing decoded and at the next one it decoded fine. The horizontal scroll did tend to cage my eyeballs after a bit. :-) My K3 was essentially fully operational right after assembly, using all the default settings. I set up my TX EQ using advice from K9YC, and I often get unsolicited "great audio" comments in the 3% SSB time. I lost most of my hearing many years ago, and I've got the RX EQ simulating the response of my hearing aids [as much as it can], which helps a lot. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 9/24/2015 3:09 PM, KC6CNN wrote: > I am looking for someone with more experience than me with using the K3 on > CW. > I have my K3 set to about 75 percent RF gain, and the width set to around > 300. > ATT is off and Pre is off I do not have the dual filter on, and no afx on.

"If you're seeing E's and T's, try using a much narrower bandwidth, 50-150 Hz, and turn on the noise blanker to reduce the level of impulse noise. I recommend using THR 2 or 3 for most signals, and THR 1 for very weak signals. These fixed settings usually work better than AUTO. When there is no CW signal above the required threshold, you'll see random characters decoded" I am trying some of the suggestions both on and off list. I guess much depends on my area noise, antenna and there is not one size fits all settings. I appreciate all the help and suggestions. It gives me things to try and see what works for me. Now if I can get every one to zero beat me. hihi I call cq and it seems like the guys that have to really try to go slow for me get right on zero beat. Then there are those that I have to hit the rit button and seems like I spin the rit knob like crazy. So I am now being cautious and trying to zero beat each person I answer.

I'm sure there will be a run on these board just like the new VCO. I'm also sure that many on this list would simply pre-pay the full amount or a deposit to secure units (we are all waving our hands at you here !). Both the new KIO3B and KXV3B board are two very worthwhile additions for K3's owners.

Living just two blocks for a shopping center doesn't help! For me turning on the AFT filter is helpful in reducing background noise (both random and close in signals during contests); tuning is then a bit tight but using three digits showing for fractions of a kHz makes it manageable. I leave the RF gain fully on. To reduce noise levels in general (which helps with CW too) I added a second receiver (SUB RX in K3), attached it to a 20-meter Beverage antenna via the AUX antenna input option and turned on the DIVERSITY MODE RX feature. With these additions, the K3 does a better job with the CW decode as well, although I seldom look at that any more. If you like, I'll send you a writeup on my 20-meter beverage; I wound my own cores for the 450 to 50 ohm matching transformer. To my surprise - with just 70 feet of back fence room, I gained over 2 S units for S/N, as noted on my P3 with I hook up the beverage to that for testing. 73, Phil, W0XI, Lawrence, KS. > > --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From fsmeier at telus.net Fri Sep 25 13:00:04 2015 From: fsmeier at telus.net (Fred Meier) Date: Fri, 25 Sep 2015 10:00:04 -0700 Subject: [Elecraft] OT: Small solar array to handle just the shack, In-Reply-To: <50DCDACE-35F4-4D48-8D34-9FDE002A3195@elecraft.com> Message-ID: hi Wayne. I just read your post about wanting to try a limited power solar array with much interest. I think is is a brilliant idea. Here are a few initial thoughts which I also had to consider when planning my own backup power. I built a parallel capable switching array into my last home. What I found to be vitally important in my installation was the need to automate the transfer of power sources for safety first and convenience second. My greatest initial expense went into the acquisition and permitted installation of an ASCO automatic transfer switch. My electrician and the electrical code insisted that this was necessary to protect the utility personnel who would have to work on whatever caused the grid to fail in the first place. While I understand the operation of these things, I not only hired a qualified electrician to hook it up, but I took out every permit necessary for the work so that the installation was legal, and equally importantly, that my insurance carrier would have no excuses should the unthinkable happen. Just a thought. There are manual means to transfer between utility and solar power but they are ponderous and inconvenient. They are also potentially hazardous if not executed with absolute diligence. I trust this gives you a little grist for the mill as you begin to explore your project?s feasibility further. Stand alone systems that do not parallel with the utility are much easier to deploy but they require redundant wiring and are difficult to make attractive (hidden from view so that She who makes the rules will approve.) I will watch this topic with interest since most participants just cannot take these things off of the forum.

Like UPM model EM100.? It is a plug in 120 vac monitor that reads voltage, power being consumed, you put in the cost per KW and it calculates the $ usage.? It was a eye opener for some of the appliances, computer, servers, lights etc.? Not withstanding the electric range I assume everything else is plug in except the LED lights, you can calculate that in your head.? Anyway that will give you a start on what your total house load is sans the stove.? There are solar calculators on line that will take that info and when you give them your long and lat, will calculate the worse case winter solar power needs.? As for me, the 100 w radio, computer and LED lights here are running nicely on a 85 w panel and a 140 Ah battery for normal SSB use.? No I don't contest with it only, and yes I have a booster charger as standby.? Just a different approach.?

I'm looking for something smaller and simpler since our electricity use is very low overall. Sticking with the original title of supplying only lighting, computers, and shack, I'll provide some general information that may help you think about designing a suitable system. My QTH is in a clearing surrounded by very tall redwoods, so an array of solar panels doesn't get a lot of illumination. As a result, I've made no effort to run 120V gear from it. My system is pretty simple. It starts with four 55W panels retrieved from the dumpster at an agency where a neighbor ham maintained remote instrumentation sites. Because of the shadows cast by the trees, I have two strapped together and located to catch the sun before noon, the other two for the end of the day. I use a Genasun MPPT charge controller between the panels and a pair of Trojan 6V 220 Ah lead-acid batteries. This system runs everything in my shack with the exception of the computers, the rotators, the SteppIR controllers, and my power amps. For lighting, I'm using the LED strips sold by a Pacificon vendor. Four strips taped to the ceiling provide illumination that's adequate for operating in the shack, and draw about 1.2A. The low power 120V stuff is connected to a small UPS. Because the draw VERY little current, a UPS can keep up for quite a while. If I want to run power during a power failure, I can fire up the Honda 2000i. The downside of this system is that the lead-acid batteries discharge curve starts around 12.5V and goes down below 11V for full capacity. That's fine for a KX3, but not great for a K3. The batteries cost me about $240, the Genesun about $120. The Genesun is available in several voltage and current ranges, and for both lead-acid and several Li chemistries. Buy direct from Genesun. This system can yield 33Ah or more during the summer half of the year, but dips to MUCH less during the winter months. Also, if I want to contest with the K3s, I need a lot more power than I can get from this system, and I'd like higher voltage to keep the signal cleaner (those reading the mail may not know that the IMD in the K3 is lowest at high DC supply voltage). So -- for contesting, and during the winter months, I must float charge the batteries from a small regulated supply. 10A is enough to keep up with a single K3 at 100W, but 20A is needed for heavy duty SO2R. Because of their relatively low voltage discharge curve and the K3's need for higher voltage, I'm searching for battery chemistry with a discharge curve that stays above at least 12V, and higher would be better. There are some Li chemistries that are candidates, but cost is currently prohibitive. If you have enough batteries and enough sun, you can start thinking about inverters to run your fridge and other 120V stuff when the power drops. Samlex has models for several power ratings, and two lines -- one that meets FCC Part 15 Class B, and another that does not. Appliances like refrigerators require a lot more current to start than to run. There are refrigerators specifically designed to run on DC for off-the-grid homes. Samsung makes both computer monitors and TVs that run from a nominal 14V. I'm running their monitors from my 12V system, and they work fine. My cable modem and wi-fi router both run from 12V; they're not in the shack, so I run them from a sealed 12V lead-acid cell that is float charged by a linear wall wart that gives it a bit more than the gear draws. The result is a poor-man's UPS that holds internet up longer than Comcast does. :) Batteries for their fiber electronics repeaters are rated for 6 hours of operation, and it's common for power failures here in the Santa Cruz Mountains to last a LOT longer. And they want to sell me a package telephone service? No thanks. 73, Jim K9YC From n1rj at roadrunner.com Fri Sep 25 16:05:39 2015 From: n1rj at roadrunner.com (Roger D Johnson) Date: Fri, 25 Sep 2015 16:05:39 -0400 Subject: [Elecraft] OT: Small solar array to handle just the shack, computers, and lighting In-Reply-To: <56059C2B.3050608@audiosystemsgroup.com> References: <50DCDACE-35F4-4D48-8D34-9FDE002A3195@elecraft.com> <56059C2B.3050608@audiosystemsgroup.com> Message-ID: <5605A913.6070309@roadrunner.com> A possible solution is a 24 volt system.

On the earphone side, I think the drivers are optimized for communications, and that is fine. They are very sensitive, and I rarely operate with the AF gain beyond about 9 o'clock unless I close down the filters in CW mode. The passive noise-reduction via the fit of the ear pads is outstanding. I can barely hear when the KPA500 fan commences to roaring. Regarding the microphone, I went with the HC7 dynamic over the iC electret element because the HC7 seemed to me to have better built-in EQ that would be favorable for good communications audio, than the iC. The HC7 requires a bit more gain, but the K3 can easily provide it. I connect via the front-panel Mic connector on the K3, and use the built-in K3 mic preamp for the front panel microphone connector that is accessible via the menu options: Menu > MIC SEL : FP.L (with the preamp engaged by pressing the "7" keypad key while in the above mode. I find that a front-panel "Mic" setting of about 50 works very well, and I generally use a front-panel compression setting (CMP) of about 18. Close-talking the microphone will probably be required, unless you naturally speak loudly. I do not. As a starting point for the EQ, I would suggest that you begin with the following settings: 1 -16 2 -9 3 -4 4 -6 5 -2 6 +5 7 +10 8 +10 The resulting tx audio is very articulate, and sounds good to my ear and evidently to others who had commented favorably on the audio quality without being asked. I happen to be a big fan of the Heil HC5 element, which sadly, is no longer being manufactured, and with some significant EQ, this HC7 can be made to sound pretty similar. This is a very subjective topic though, so some experimentation is in order for your particular voice and personal preferences.

All units are connected to the computer via USB so I can use the appropriate Utility. Now, when I try to connect the P3 to the K3S there is this behavior. I can only use the USB *or* the RJ45 serial. Once I connect to the RJ-45 serial, the USB is disconnected at the K3S and I lose access to the COM port(s). I am guessing there is no value to the RJ-45 port once I decide to use USB, and I should use the USB-DB9 connector to connect the P3 to my PC for the P3 Utility.

You must use the CBLP3Y cable between the K3S RJ-45 connector and the P3. Note that the connector with 2 cables plugs into the XCVR DE-9 connector on the P3. If you are using a USB to RS-232 adapter between the computer and the P3/K3S, refer to the diagram on page 19 of the manual - connect the USB to RS-232 adapter to the P3 "PC" connector and connect the P3 XVTR connector to the K3S using the E980297 DE-9 to RJ-45 cable.

(Note that the noise from this can be intermittent rather than constant.) That happened on a pole near me. I walked around the neighborhood doing some DFing with a portable AM radio, identified a suspect pole, and noted its ID number. When the power company crew arrived a lineman climbed the suspect pole and immediately spotted a damaged part. The crew was amazed that I was able to track down the fault that accurately. They also thanked me for notifying them as it not only prevented a likely future outage but also eliminated a system loss point. (From what they said leakage of this type costs power companies more than you'd realize.) 2) Improperly designed (or "cheated" designs which claim to but don't meet Part 15 spec) consumer electronics can throw RFI/EMI hash back out onto the power feed and thus radiate it for quite a distance.

I've encountered more than one device that is "Part 15 Compliance", when indeed measurements confirm it only has the "Part 15 Label". With companies performing self certification, first there is no assurance the results are accurate and second, manufacturing changes are implemented often without performing the certification measurements. Yes, I know what is supposed to take place......but it does not. Thus once certified, always certified. Do note: There are several "grow lights" on the market today that are "Part 15 Certified" and these have been found to be generous noise generators. {Perhaps your neighbor would share some of his crop to make your "pain" more tolerable.} Also some brands of ballast are noted to be sold to residential use customers when indeed they are labeled for commercial service only.

Message-ID: <026801d0f882$9be1ae40$d3a50ac0$@carolinaheli.com> On 40m my TV turns off and on by itself when I transmit. I'm thinking that it's related to grounding because I've not figured that out yet. I have a roof mounted mast that holds my dipole. The coax comes down through the roof, routes through the attic down inside the wall to the station. I've been told I need to ground the feedline BEFORE it enters the house but I'm not sure how to get a ground correctly up to the roof. No matter how I run the ground a lightning strike would likely ignite my house inside the attic if I run it inside the house. I have a low pass filter installed just before/after the Rig. The plan I'm thinking of so far. 1. Run an 8 gauge dedicated power feeder from my main panel (on the opposite side of the house) to the shack with a 20A breaker. The 8Ga is to lower ground losses. 2. Install a ground rod outside my shack and run a heavy gauge to the shack to bond with the dedicated power line ground. 3. Ground all gear in the shack to the dedicated power ground. 4. ?? maybe do a run of 14-2 romex with all three leads bonded together up to the mast, install a mast antenna switch and ground it with the 14-2. Thoughts /comments? Running only 100w into a Buckmaster 7 Band OCF dipole at 35' per the instructions. The dipole is broadside to 45 degrees for EU coverage. Thanks in advance.

RF is getting into the house wiring. I suggest adding a choke balun at the feedpoint of the antenna to reduce "RF in the shack" and wrapping the power cord of the TV around a ferrite rod, toroid or bead for several turns. Google K9YC's RFI tutorial for details. OCF dipoles are very bad for RF in the shack due to the degree of unbalance. Radio Shack used to sell little square ferrite toroids that split apart so you can wrap wires around them without interference from plugs, etc. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 26 Sep 2015 20:41, ae4pb at carolinaheli.com wrote: > On 40m my TV turns off and on by itself when I transmit.

Low power (~80 to 100 watts) did not seem to bother the TV but it was a regular problem at power?s much over 100 watts. My solution which seems to work flawlessly so far with max power of 600 watts is that I took a whole bunch of the clip on wrap around conductor ferrites and put it on the power cord. They run for about half the length of the 120 vac power cord to the TV set, about two dozen ferrites. I had the same problem with the Bose table-top radio upstairs. Key down at >100 watts would invariably turn on the radio. But, the Bose table-top radio uses the power cord as a default FM antenna so wrapping in ferrites required another antenna solution. So, I created a makeshift FM antenna up on the roof and ran RG-6 cable to it where it connects with standard TV like RG6 cable connectors. This fixed that problem too. 73, phil, K7PEH > On Sep 26, 2015, at 10:57 AM, Don Wilhelm wrote: > > I would think it is more related to the susceptibility of the TV to RF than to any grounding issues. > You could try ferrites on the TV power and all other cables. > > 73, > Don W3FPR > > On 9/26/2015 1:41 PM, ae4pb at carolinaheli.com wrote: >> On 40m my TV turns off and on by itself when I transmit.

That connection is a NEC requirement and is necessary for safety. All ground rods *must* be connected together unless they are more than 100 feet apart. You cannot create an RF ground by connecting to a ground rod. It is only for AC safety and a measure of lightning protection. OCF antennas can be difficult to tame for RF in the shack. Use of a very good quality common mode choke at the feedpoint (in addition to the 4:1 balun) may help. 73, Don W3FPR On 9/26/2015 1:41 PM, ae4pb at carolinaheli.com wrote: > The plan I'm thinking of so far. > > 1.

In digital mode contest traffic it is necessary to switch to RX immediately after exchange has been sent. I learned that the way to do this is to send KYW;RX; to the serial interface. The RX; after KY will ensure immediate switch to receive and the W in KYW will ensure that the RX; will be interpreted after text sending is finished, i.e. will not interrupt ongoing transmission. What surprised me is that when I send something like: KYWCQ CQ CQ DE OK4RM;KYW DE OK4RM OK4RM PSE K;RX; i.e. split a long text in shorter chunks. In such case I believe all the texts are sent (I have to verify that yet, though) but the effect of the final RX; disappears. Is this a mistake in my program workflow or could that be a firmware peculiarity? (I hesitate to call it a bug as everything else seems to work perfectly.) I think there will be no problem for a contest but if I wanted to use the same pattern for longer exchanges in casual digi QSOs that would make things a little bit more complicated.

We have done all of the somewhat static value checks and tests up to this point. When we turn the unit on (with no smoke or heating parts), the ATTN yellow light comes on, then off, then the RIT/XIT light flashes green, then RED (not really orange, to my eye. Yes, the 100K R9 and R10 around the LM358 op-amp are installed correctly). Then it goes out, then the ATTN light comes on again briefly, then it goes out. We get NOTHING on the LCD Display. We've run all of the continuity tests on the data lines, etc. If we power on the rig while holding the DISPLAY -or- the EDIT button, then the LED sequence is as above, except that the ATTN light stays on while the button is pressed; releasing the button shows "109" on the LCD (looks like the LCD is working). If I knew what the firmware was expecting from the hardware between the light sequence and the initial LCD display, I could better determine where we are finding some error. I suspect the CPU is expecting some condition that we aren't able to satisfy because of an error somewhere that we've not found yet. Suspecting that perhaps the EEPROM was a little scrambed, I held the EDIT and DISPLAY buttons down while powering? on - that didn't really do anything, still no LCD display. Can anyone suggest any further troubleshooting, or locations to look at?

I have experienced RF getting into the Direct TV / satellite receiver causing it to change channels, turn on and off, and reset. It is the fact you are radiating RF which is the desired intention and this RF is getting into the "plastic box" of the receiver. Plus many of these receivers use RF Remote control as opposed to IR Remote control. If it is just the TV that is turning on and off, I suggest putting common mode chokes on the AC power cord at the TV and also on any other inputs or outputs at the TV. This also could be an issue where the TV Remote control is a RF Remote as opposed to a IR remote. I've found these RF Remote receivers have basically no selectivity and any RF close by will or can cause issues. Your roof mounted mast should have a ground positioned as close as practical. A driven rod is required. Use #6 copper from the roof mast to the ground rod with suitable clamps. Straight runs preferred with large radius bends if and where needed, otherwise no sharp bends. Also some form of lightning protection is needed at the point or before the feed line(s) enters the house. This can be attached to the same ground system. Now here's the kick in the pants..........this ground rod must be bonded back to the AC Mains ground and this needs to occur outside of the house even if it means running 50 ft or more of copper between the two grounds. This is per NEC. I trenched mine in about 6" deep around the foundation. All of my feed lines and rotor control lines enter the house at an eve vent, traverse across the attic and drop down through the ceiling to the operating position. My lightning protection is at the point the feed lines exit the tower adjacent to the house. I do not have any ground from the station operating position to the outside world. I only use 3rd pin safety ground. Use dedicated jumpers between each piece of equipment to the common power supply ground terminal. Do not daisy chain pieces of equipment. I make my ground jumpers using #10 auto primary wire with suitable crimp lugs attached on each end. You may also need to place a common mode choke on the feed line near or at the radio. This can be the coax jumper between the radio ANT and the SWR/Pwr meter or input to the external ATU. Running only 100 watts, I'd think the #8 ga power feed from the breaker panel is way over-kill. I's spend my money on copper in other places. Just run a dedicated 20 amp service. If you install a ground rod outside of the shack, this rod must be bonded outside of the house back to the main AC Mains driven ground as well. Finding the problem and applying the proper solution is the challenge. Throwing random solutions around likely cost money and won't produce results. Just remember that grounding is a defined system and done correctly will protect not only the structure but the equipment. Yet grounding not properly done can be extremely dangerous. 73 Bob, K4TAX K3S s/n 10,163 On 9/26/2015 12:41 PM, ae4pb at carolinaheli.com wrote: > On 40m my TV turns off and on by itself when I transmit.

I finally got it working, but here's what I tried that ultimately proved useless: -- Added a counterpoise on the floor of the shack for 40m -- Added ferrite cores on all cables connected to the tv; power cord HDMI; audio line out -- I even opened up the tv housing and placed cores over interconnections between boards. Ultimately, I finally figured out that rf was getting into the touch-sensitive switch matrix on the tv at the lower right corner. So, I found cardboard box with dimensions such that if it sat on the table top along with the tv with the opening facing upward, the top edge of the box completely covered the switch matrix up to the point where the bezel met the tv screen. Then I made a simple Faraday shield with some aluminum foil completely coating the inside of the box, and then another sheet of aluminum foil covering the outside of the box, but the two foil shields did not connect together electrically. Then I ran a wire from only the outside shield, to the underside of a screw head of one of the screws that holds on the back cover of the tv. Then I measured where the infrared LED sensor for the remote was located with respect the to edge of the tv bezel, and punched a hole through the box such that with the box in position to completely cover the area of the keypad, the remote would still operate the tv. I also made sure that punching the hole did not connect the two layers together. Yes, it's really ugly and strange looking, but my wife can watch tv now when I'm on 40m, and I don't have to keep resetting the settings on the tv that got clobbered every time I operated. Prior to 'The Box', as little as 20 watts would make the tv do all kinds of interesting things. With the shield in place, I can run full power from the KPA500 and it doesn't bother the tv in the least. This is with all of the ferrite cores that I had previously installed, removed. This may or may not be the source of the problem with your tv, but it's a very easy thing to try as a first check. Good luck with resolving your TVI issue. 73, Dale, WA8SRA > On 40m my TV turns off and on by itself when I transmit.

Sometimes the rubber boot slides a bit on the connector and it appears to be fully mated, but isn't. It must be seated until the plastic tab on the RJ-45 clicks. There is a jumper connection in the RJ-45 connector on this cable that tells the K3S that this cable is in use. The fact that with nothing connected to the DE-9 connectors, you appear to be communicating with the K3S over USB (your step 6) suggests that the jumper is not being detected, which is why I suspect the cable may not be fully seated. 73, Lyle KK7P > Let me summarize my tests in hope someone has an idea. > > 1.

It would be better to use only one. Since you have a USB to serial adapter working with the P3, I suggest you remove the USB cable (unless you are using the internal K3S soundcard), and connect the K3S and P3 with the E980297 cable as shown on page 19 of the manual. You would then change the RS232 menu entry to the baud rate being used by your software application (use 38,400 if possible). I believe that is a better 'workaround' than you are now using. My guess is that you may have a defective CBLP3Y. You can still use the audio path provided by the USB audio section if desired. If by 'Data Terminal Mode' you are referring to displaying the K3S decode of CW and DATA on the P3 - that is not displayed on the P3 screen, but with the SVGA option in the P3, it can be displayed on the attached SVGA screen - see the SVGA option manual. 73, Don W3FPR On 9/26/2015 4:32 PM, Byron Peebles wrote: > I found a workaround by using the Elecraft RJ-45-to-Serial cable and a > separate PC-to-P3 USB-to-serial. > I am uncertain how to test the RJ-45-to-Serial cable, but at least it > no longer "breaks" my K3S to PC USB. > > Data Terminal Mode in the P3 seems like a secret, but I'm hunting for > it now. 73, Byron > From joel.b.black at gmail.com Sat Sep 26 17:32:19 2015 From: joel.b.black at gmail.com (Joel Black) Date: Sat, 26 Sep 2015 16:32:19 -0500 Subject: [Elecraft] [KX3] MH3 Mic Holder "Ring" Message-ID: Is there some place from which I can purchase the mic holder ?ring? that attaches to the MH3?

Once they are fixed the noise goes away. For Wire fences I put a little grease on the join after I remake it to discourage future corrosion. For tape and string I leave tails sticking out of the knot, burn these back a little with a lighter then twist the now exposed wires together We use an electric fence here, in part to stop the Horses Eating Coax I had for a while an Icom 7800 and even a hint of fence noise would drive the AGC insane and I spent much time mending my neighbors fences. The K3 is Much less sensitive to impulse noise triggering the AGC and as a result I now get less exercise and fewer electric shocks! On 26/09/15 02:37, Dale Putnam wrote: > hmmm..

Jerry, I had this exact problem on 40m with a 42" Samsung LCD tv. I finally got it working, but here's what I tried that ultimately proved useless: -- Added a counterpoise on the floor of the shack for 40m -- Added ferrite cores on all cables connected to the tv; power cord HDMI; audio line out -- I even opened up the tv housing and placed cores over interconnections between boards. Ultimately, I finally figured out that rf was getting into the touch-sensitive switch matrix on the tv at the lower right corner. So, I found cardboard box with dimensions such that if it sat on the table top along with the tv with the opening facing upward, the top edge of the box completely covered the switch matrix up to the point where the bezel met the tv screen. Then I made a simple Faraday shield with some aluminum foil completely coating the inside of the box, and then another sheet of aluminum foil covering the outside of the box, but the two foil shields did not connect together electrically. Then I ran a wire from only the outside shield, to the underside of a screw head of one of the screws that holds on the back cover of the tv. Then I measured where the infrared LED sensor for the remote was located with respect the to edge of the tv bezel, and punched a hole through the box such that with the box in position to completely cover the area of the keypad, the remote would still operate the tv. I also made sure that punching the hole did not connect the two layers together. Yes, it's really ugly and strange looking, but my wife can watch tv now when I'm on 40m, and I don't have to keep resetting the settings on the tv that got clobbered every time I operated. Prior to 'The Box', as little as 20 watts would make the tv do all kinds of interesting things. With the shield in place, I can run full power from the KPA500 and it doesn't bother the tv in the least. This is with all of the ferrite cores that I had previously installed, removed. This may or may not be the source of the problem with your tv, but it's a very easy thing to try as a first check. Good luck with resolving your TVI issue. 73, Dale, WA8SRA > On 40m my TV turns off and on by itself when I transmit.

Mounting solar panels in a flat position may turn out to be the most practical. The conventional way is to angle them towards the sun at an angle equal to your latitude, but even at 46 degrees here in Montana the difference in output between 0 and 46 degrees is only about 7%. Hardly worth the trouble of dealing with the mechanics of angle mounting or seasonal adjustment. At Wayne's lower latitude, this is even more the case. Our RV has 12A worth of panels and they're mounted flat on the roof. They charge four Trojan T-145 6V (440AH) golf cart batteries (via a regulator) and we've never run short of power. BTW, the batteries have been in service for almost 12 years. There's a 1500W inverter for the TV, SatTV receiver, computer(s), etc. The one thing we don't do is power the 1000W microwave oven via the inverter. It requires 90 amps from the batteries to operate the microwave and I hesitate to draw that from the battery for long periods of time for fear of warping the plates. I also have a small Air 403 windmill that mounts to the RV's rear bumper that's good for 25A in a stiff breeze. It also gets lots of interest from other RV'ers. Especially at the Quartzite, AZ gathering. (:-) 73!

As Don suggests you are really dealing with four grounding systems. Your RF or rig ground, a lightning ground, your NEC or house power ground (neutral), and finally the safety ground (green wire) ground which is really part of the NEC ground. Often the requirements of one system will be at odds with other grounding requirements. For instance you generally want a high impedance for RFI issues and a very low impedance for lightning grounds. One system defeats the other so they really need to be separate systems. Your NEC and lightning grounds have very serious safety issues so running your proposed wiring changes by your local power company can often be very helpful. Most power companies have an expert on such issues although the existence of such a person is often a closely held secret. 73 Fred, AE6QL -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Don Wilhelm Sent: Saturday, September 26, 2015 12:08 PM To: ae4pb at carolinaheli.com; elecraft at mailman.qth.net Subject: Re: [Elecraft] K3S proper grounding? Your grounding plan sounds fine, *if* and only if you connect that separate ground rod to the utility entrance ground rod using a #6 or #4 copper wire - that wire should be buried several inches and run outside your dwelling foundation. That connection is a NEC requirement and is necessary for safety. All ground rods *must* be connected together unless they are more than 100 feet apart. You cannot create an RF ground by connecting to a ground rod. It is only for AC safety and a measure of lightning protection. OCF antennas can be difficult to tame for RF in the shack. Use of a very good quality common mode choke at the feedpoint (in addition to the 4:1 balun) may help. 73, Don W3FPR On 9/26/2015 1:41 PM, ae4pb at carolinaheli.com wrote: > The plan I'm thinking of so far. > > 1.

In general I view station grounding approaches as 4 different systems, all which should be implemented. (a) All driven grounds must be bonded to each other an to the AC Mains ground and this should occur outside of the structure or house. I find no exception to this practice unless a tower is 200 ft or more from the structure at which point a ground system should be located at the base of the tower. (b) Third pin green wire or safety ground for equipment must always be in place and not "cheated" with an adapter. (c) All lightning protection should occur before any feed line or rotor control enters the building. Its ground attachment should be part of the driven ground and bonding system. Towers should have a ground from top to bottom and not relay solely on the structure alone. Don't forget to bond the rotating mast out the top of the tower to the tower itself. (d) Certain type of antennas do require a specific ground system which I refer as RF Ground. A few driven ground rods do not make a RF Ground. Those being, but not solely inclusive, verticals, slopers, end fed Zepps, long wires and such as examples. As to running a ground from the operating position to the outside ground system, I've never found this necessary with proper antenna installation. In many cases, the length of the ground conductor becomes or acts as an antenna system and actual picks up RF from the transmitting antenna thus placing the station above RF ground. {Opinions will vary on this point.} I view if one has RF on the equipment, don't run it to ground. Change the antenna and / or feed system to get the RF to the antenna where it will do some good and thus not just warm the earth worms. 73 Bob, K4TAX K3S s/n 10,163 On 9/27/2015 3:20 PM, Fred Townsend wrote: > erry there is NO one size fits all grounding solution.

Message-ID: Hi everyone, Just a quick note to let you know that Wizkers 0.10.0 is now released and available in the Chrome app store, always free as in $0, and always free as in open source at github.com/wizkers . For current users, Wizkers will automatically update, no need to do anything in particular. For new users, you can visit https://goo.gl/DgLqXH to install it (yes, this is a normal link, nothing to worry about, this is the Google URL shortener). New in this version for KX3 users: - Piglets are now supported! Just use "TCP/IP" in the serial connection dialog, enter the IP/Port of your Piglet, and make sure the Piglet/Radio are both setup for 38400 baud. That's it. - You can now configure all the macros in the data terminal mode (Settings menu). As a reminder: Wizkers can be installed from https://goo.gl/DgLqXH and the complete documentation is online (and up to date) at wizkers.github.io/wizkers-doc/ins/elecraft-kx3/ . Though you can already use Wizkers on two computers for remote rig operations (http://wizkers.github.io/wizkers-doc/ins/elecraft-remote-kx3/) , the next version will hopefully make it even easier. Enjoy, and as always, your feedback and encouragement is always very appreciated! 73 de Ed, W6ELA From jim at audiosystemsgroup.com Sun Sep 27 17:49:29 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sun, 27 Sep 2015 14:49:29 -0700 Subject: [Elecraft] K3S proper grounding?

What you're calling a ground system for an antenna is NOT a ground system at all. Rather, a radial system functions two ways -- it acts as a low loss return for antenna current and and as a return for the fields produced by the antenna. In other words, a radial field SHIELDS the antenna and its fields from lossy earth so that power is not wasted in the soil under the antenna. In the absence of a radial system, we often use a COUNTERPOISE -- a wire connected to the return side of the coax (or the antenna tuner) to act as the return for current. The primary difference is that the counterpoise is simply another radiating part of the antenna, but it does not provide the shielding function. Yes, broadcast radial systems are usually buried, but the skin depth of soil usually extends FAR below the topsoil on the AM broadcast band and on 160M, so the radial system is still providing the low loss return and shield. Another benefit of radial systems is that they provide capacitive coupling to a wide area around an antenna, which improves the path to ground for lightning. 73, Jim K9YC 73, Jim K9YC From kd5byb at gmail.com Sun Sep 27 18:41:45 2015 From: kd5byb at gmail.com (Ben Hall) Date: Sun, 27 Sep 2015 17:41:45 -0500 Subject: [Elecraft] Bucket treatment In-Reply-To: <56086485.8070607@audiosystemsgroup.com> References: <3.0.6.32.20150927132226.00e49248@pop3.dccnet.com> <56086485.8070607@audiosystemsgroup.com> Message-ID: <560870A9.4070801@gmail.com> > I've had a considerable amount of satisfaction using a sledgehammer.

Mounting solar panels in a flat position may turn out to be the most practical. The conventional way is to angle them towards the sun at an angle equal to your latitude, but even at 46 degrees here in Montana the difference in output between 0 and 46 degrees is only about 7%. Hardly worth the trouble of dealing with the mechanics of angle mounting or seasonal adjustment. At Wayne's lower latitude, this is even more the case. Our RV has 12A worth of panels and they're mounted flat on the roof. They charge four Trojan T-145 6V (440AH) golf cart batteries (via a regulator) and we've never run short of power. BTW, the batteries have been in service for almost 12 years. There's a 1500W inverter for the TV, SatTV receiver, computer(s), etc. The one thing we don't do is power the 1000W microwave oven via the inverter. It requires 90 amps from the batteries to operate the microwave and I hesitate to draw that from the battery for long periods of time for fear of warping the plates. I also have a small Air 403 windmill that mounts to the RV's rear bumper that's good for 25A in a stiff breeze. It also gets lots of interest from other RV'ers.

I do know that the local Red Lobster restaurant took a big financial hit when he passed away - it was the site of many evening-long discussions on our clients' problems and the oddities that he found since his last trip through here.

The ]Colour Rendering Index (CRI) of these lamps will tell you how faithfully they will reproduce all colours of the spectrum. If you find a lamp without this information on the side of the box, then be careful and perhaps don't buy it. A CRI of greater than 90% (0.9) with a colour temp between 3000-4000 will be adequate for the shack and reading of resistors and colour codes. It turns out that brown and deep reds are very difficult colour to faithfully reproduce from blue rich white light, which isn't a new phenomenon since long arc fluorescent, CFL and LED all derive white light the same way. For reference low pressure and high pressure metal halides have a CRI of 100% which is why you find them used in art museums, ditto tungsten et al. However pay careful attention to noise from these more modern lamps, the EMI from some cheap and nasty LED/CFL lamps is just hideous. We all want to preserve the noise floor for our Elecraft RX's, just to keep this on topic. 73 Matthew VK5ZM On 28 September 2015 at 04:21, Dale Putnam wrote: > For those looking at CFLs or LEDs in the shack, and presuming that is > where you built, very close attention must be given to > the color and intensity of the light emitter.

The only thing i looked for was color temp and they had to be "dimmable". After I swapped all the CFL's and tubes out, my background noise dropped by around a half S unit. I then killed all the lights in the house and the noise floor stayed the same. To check for sure, I put a rubber duck antenna on my KX3 set it to AM, 6 meters and turned all the lights on. Even with the antenna right on each bulb, I didn't see any significant change in the background noise. My closest neighbor had all CFL's and I could take the KX3 near his house when he had his lights on. S7 noise on 10 and 6. After he had a CFL catch fire, he bit the bullet and went all LED. Now, as long as the power company keeps the trees out of the lines and the insulators clean, my noise floor runs pretty much right at whatever atmospheric background is. I don't know what type of LED bulbs my neighbor got but they are quiet.

Further, lightning is NOT a DC event, it is an RF event. It's an impulse, with broad energy peak around 1 MHz. [Fred Townsend] Correct on all scores Jim I think you have tunnel vision on bonding. Jim as others suggested this was really an EMI issue and I was addressing this as a system or EMI issue. In this case chokes are appropriate for signal AND power cords containing neutral. I don't believe anyone suggested chokes on bonding conductors. However you suggested everything should be bonded and I merely asked how you bond a choke. Also the NEC as well as other codes prohibit tying neutral and safety (green wire) together. Two cases I called out in my four different parts of the system. So no you do not tie all grounds together. Furthermore I think the whole issue of grounding is exacerbated by the overuse and incorrect use of the word 'ground'. The Brits prefer to use the word 'earth' which helps a little. I would prefer to bury the word 'ground' and replace it with context appropriate words like 'signal common' but that isn't common practice. 73, Fred, AE6QL 73, Jim K9YC ______________________________________________________________ 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 fptownsend at earthlink.net From w0wfh at yahoo.com Mon Sep 28 02:17:27 2015 From: w0wfh at yahoo.com (W0WFH Bill) Date: Mon, 28 Sep 2015 06:17:27 +0000 (UTC) Subject: [Elecraft] FS K2 loaded Message-ID: <452086337.1753149.1443421047185.JavaMail.yahoo@mail.yahoo.com> For Sale I take Paypal.

I will have a look (just received and read your email). My app has no link yet and is not hosted on any source repo yet as it is really in the very initial phase. What it does as of now - it makes a list of available COM ports and has some buttons to establish the connection, receive callback handlers, etc. Then I have a small area where I can enter any test and send it to KX3. The receive handler will automatically take care of the response. Recently I added a small decoder and few controls, so when, for instance FA00003575012; is received, the VFO A display is updated automatically, same for all other codes (except that I don't have a GUI "receiver" for every code, just a few basic ones). Everything is wrapped in Angularjs, so I don't have to program data binding. I would like to have at least a practical control panel (main controls for casual operation) and some basic logging functionality because I really love KX3's decoding capability, no need for additional setup of external sound card, less cables, etc. 73 Jindra OK4RM 2015-09-27 23:33 GMT+02:00 Edouard Lafargue : > Jindra, > > Very happy to see yet another chrome packaged app coming up!

If your K144XV meets the specification in the data sheet (system MDS -144dBm, and assuming a 500Hz bandwidth) then you should be hearing 2m antenna noise quite clearly in your suburban location. 73 from Ian GM3SEK From w4rks73 at gmail.com Mon Sep 28 08:57:31 2015 From: w4rks73 at gmail.com (James Wilson) Date: Mon, 28 Sep 2015 07:57:31 -0500 Subject: [Elecraft] {Elecraft} SSB Net for Sunday, September 27th Message-ID: The SSB net meets each Sunday at 18:00 UCT (13:00 CDT) on 14,303.5 MHz plus or minus QRM.

I was operating below 7.2 MHz, SSB. Honestly, I didn't notice any difference in noise or propagation. Part of the time, I was in contact with stations in Missouri, Virginia, and Wyoming. It was early evening, from around 7:30 to 9 PM, here. Because I was driving, I could only observe the eclipse visually for a few minutes before heading away from it. Visually, it was quite a sight. I *wish* I could fit the K3 into mobile ops, but the car is a Honda Civic with severe space limitations. 73, matt W6NIA On Mon, 28 Sep 2015 06:02:40 +0100, you wrote: > >On 28 Sep 2015 05:52, Matt Zilmer wrote: >> >> The blood moon was pretty fantastic from Montrose, CO. >> >How did it affect radio conditions, Matt, particularly as regards noise and on which bands?

After putting in the synthesizers, I also upgraded to Firmware 5.33, which was the latest at the time (I see that 5.35 was released the day after I did the upgrade). The SYNTH OK messages were seen on the menu, and the configuration was redone as specified in the instructions. I also took care not to lose any washers inside the radio, and to not disturb anything within the radio. Since then, I have had a number of issues with my K3. #1- DVK doesn't work via N1MM command. VFO B says "DVK Not installed", but I do have one installed. I can also play the messages by pressing the Message key. I checked the config menu, and it says it is installed. #2- I have heard a number of loud audio "pops" since the above changes. #3- I have actually lost audio several times with no VFO B errors- audio just stops in the middle of a QSO. #4- During CQWW RTTY, if I was transmitting and pushed a key- say A/B, or Rev- transmitting stops, I get an "Error PTT" followed by an "Error Key" in the VFO B window for a few seconds each, then the radio clears itself. I can then resume transmitting. No audio loss while this is happening. #5- During the contest, N1MM would show the Radio Mode as PSK. The program would keep on transmitting RTTY, and what went into the log was indicated as RTTY, the K3 was working properly in RTTY and indicated it was in Mode D FSK correctly. #6- When I tried to use Diversity reception, the K3 would switch into Diversity mode correctly. After a while, I would get a sudden total audio loss and one of several DSE errors: E015555, E005555, 00C2C2, 003030. #7- Turning the diversity OFF seemed to decrease the severity of In all cases, power cycling the radio would clear the error and the audio would be restored. I've tried reloading firmware, and it reloaded without a problem. Yes, I power cycled the radio immediately after the firmware update was done. I haven't tried downloading the firmware a second time from the web site, and then reloading it into the radio but I suspect that may be the next thing that I try. At this point, I'm open to suggestions. Thanks for input!

(I've got two antennas I'd like to compare using different received carrier signals - e.g., from a neighbor's TX, W1AW RTTY bulletins, etc.) I see that the K3 can display the RMS value of receiver AF output (mVp-p), unaffected by AF GAIN control. And after that stabilizes, I can also get dbV to display. (How long is the stabilization period? Does the display sample and hold a single value, or is it averaged and continuously updated? It seems like the former.) Is this the way to go, or is there something I can do with the P3 that will give a readout in dBm? (I guess I could make a rough graphical measurement by setting the P3 display threshold to match the weaker signal, then switching to the stronger signal, and seeing how far above that threshold it rises - with Scaling maximized.) I know there's also W8WWW's S-Meter Lite, with which I've also dabbled - presenting a digital S-meter, or relative dB, output. (Or I could do a step attenuator approach, but then I couldn't compare by simply flicking the antenna switch, and QSB would be a problem.) Thoughts?

Set the display to AFV for a couple seconds. This provides a baseline value against which the DBV display is calculated. (This means dB in terms of voltage, not the traditional, standard dBv. Thus 2x the voltage is shown as a 6 dB increase.) The measurement time is either 0.5 seconds or 1.0 seconds in the DSP code. The AFV TIME config menu item is either 500 (for 500 milliseconds, or 0.5 seconds) or 1000 (for 1.0 seconds). You'll want to dwell on a signal for twice that period to be sure the reading is accurate, then jot it down. Now switch antennas, wait again and then jot it down. The calculations in the DSP are true RMS calculations over the time period. The previous results are not averaged. Each measurement time is independent. 73, Lyle KK7P On 9/28/15 7:39 AM, Bill Conwell wrote: > I'd like to do some quick and dirty comparing of antenna output signals > using my K3 (and/or P3). > > > > (I've got two antennas I'd like to compare using different received carrier > signals - e.g., from a neighbor's TX, W1AW RTTY bulletins, etc.) > > > > I see that the K3 can display the RMS value of receiver AF output (mVp-p), > unaffected by AF GAIN control.

In-Reply-To: References: Message-ID: <56096C08.2020206@blomand.net> Ken makes a pertinent comment; "the DSP does all the rest". Suggested filters are roofing filters and serve a function of signal path and how signals outside of the DSP bandwidth can affect the receive performance. Receiver selectivity is actually accomplished by the DSP engine. Regarding the function of roofing filters, I suggest reading material such as: http://www.sherweng.com/documents/NC0B-Contest-U-2008-9.pdf Although a slide presentation, the information is clearly definable and explains the use and the application of roofing filters. If one is not anticipating CW contest operation nor has a station nearby physically that would be on the same band at the same time, then it is a good likelihood that no additional filter is required. As some have pointed out, understand that operationally the roofing filter is selected based on the DSP bandwidth selection. If one chooses to operate CW with a 500 Hz DSP BW, the 400 Hz roofing filter would not be in the signal path. Changing the DSP BW to 400 Hz or less will switch the 400 Hz roofing filter into the signal path. This would then make it more understandable why a very narrow roofing filter might not be advisable unless the need actually exists. Every one has their personal preferences based on their specific operation, physical location and proximity to other stations operating on the same band and a host of other effects. In my case, I choose the 6.0 kHz filter because I do operate some AM, the standard 2.7 kHz filter, the optional 1.8 kHz filter for SSB and the 500 Hz filter for digital modes and CW. In another of my radios I do have a 300 Hz roofing filter. I find reducing the DSP bandwidth to 300 Hz to allow this filter to be selected is typically too tight for my operating preferences. 73 Bob, K4TAX K3S s/n 10,163 On 9/28/2015 10:53 AM, Kenneth Christiansen wrote: > Hi to the Gang > > This is a subjective question but after using a 500 hz and 200 hz filter for 7 years I ordered a 400 filter for my K3s.

If a tuner is located at the rig-side of the coax, and the coax is at high SWR, it could possibly be a cause for coax radiation. A test might confirm that. Perhaps you could find a spot on 40m where the SWR is null, and no tuner is needed. If, at that point your RFI is significantly reduced, I would try feeding the antenna with twin-lead to a matching network located on the roof. That way, the coax would always be functioning as designed. In that case, a common mode choke at the load-end of the coax might also help to further reduce coax shield radiation. Something to consider.

I said that ALL GROUNDS and GROUNDED equipment must be bonded together. A choke is neither. Signal cables and power cables are NOT bonding conductors. Bonding refers to those conductors that provide a dedicated, robust, low impedance connection between all grounded elements of premises wiring. Bonding conductors are those which connect together all equipment in a station, all earth electrodes in a premises. This includes but is not limited to the EARTH connections for CATV, Telco, satellite dishes, mains power. It also includes those used for antennas where they enter a premises. In simple terms, NEC (and the laws of physics) allow as many earth electrodes as we want, but they MUST all be bonded together. > Also the NEC as well as other codes prohibit tying neutral and safety > (green wire) together. Not quite! NEC REQUIRES that neutral and green be bonded together at one, and ONLY one point in every SYSTEM, and, in general, requires that the bond be very close to the point where the system is established. [The word "system" here specifically refers to the wiring that distributes power in a facility, and to equipment connected to it.] A "system" is established when the power enters a premises, and a bond is required there. In most premises, that's the only system. A system is also established by a transformer, as might be used in large buildings to run large loads, and by equipment like a UPS. In both examples, this does NOT require a new earth electrode, but rather a bond between neutral and green at that point. The correct part of your statement is that NEC prohibits tying neutral and safety (green) together any place OTHER than where the system is established. > Two cases I called out in my four different parts of the system. So no > you do not tie all grounds together. You misunderstand the concepts. See the above. All grounds MUST be bonded together. Another important distinction -- a cable shield is not "grounded," and there is no virtue in doing so EXCEPT for lightning protection. The shield is properly connected to the shielding enclosure at each simply to make SHIELDING continuous, and thus make it effective. This is not a GROUND, it is a SHIELD connection. And in an unbalanced circuit (where the shield is the signal return), it is also signal return. When we add a common mode choke to an antenna downlead, we are preventing common mode current on the cable shield. We bond the antenna shield to ground at the point of entry, and we bond that point of entry to a the building ground, but that is to protect the premises, NOT the antenna. That cable shield is NOT a ground, it is a shield, and it is a signal return. That would work with a coax feedthrough, but it would not protect a rig connected to the antenna. To do that, we replace the feedthrough with a Polyphaser, which shorts the center conductor to the shield in the event of a strike.

Message-ID: <560974AE.70600@att.net> This is an interesting discussion. Before I purchased my K3 in 2008, I had become addicted to narrow selectivity with my previous rigs, and was routinely tuning the bands with cascaded 250 Hz filters. Since I'm nearly 100 pct. CW, I purchased a range of crystal roofing filters to try out in my K3. I have the 700 Hz (special order), 400, 250 and 200 Hz filters. I'm primarily a low band DX'er and like the flexibility of all these filters ahead of the K3's marvelous IF DSP variable filter in order to deal with varying band conditions. Lately, though, I've been using the 700 Hz and 400 Hz roofing filters almost exclusively. The K-3's DSP APF does a great job in peaking up stations near the noise level. I also employ the DXE NCC-1 noise cancelling unit with optional matched receive bandpass filters installed for my favorite DX bands. This unit provides additional attenuation and really helps augment the K3's already super dynamic range. 73, Chuck NI0C KX1, K2-10, K-3, P-3 From n4elm at bellsouth.net Mon Sep 28 13:25:21 2015 From: n4elm at bellsouth.net (William Redfearn) Date: Mon, 28 Sep 2015 17:25:21 +0000 (UTC) Subject: [Elecraft] [K1] Want K1 Tilt Stand Message-ID: <1609975716.1673894.1443461121479.JavaMail.yahoo@mail.yahoo.com> Looking for a K1 Tilt Stand.

It doesn't work that way. Radiation from coax is the result of IMBALANCE in the antenna. A ferrite common mode choke at the feedpoint can fix that. 73, Jim K9YC From k2av.guy at gmail.com Mon Sep 28 13:47:19 2015 From: k2av.guy at gmail.com (Guy Olinger K2AV) Date: Mon, 28 Sep 2015 13:47:19 -0400 Subject: [Elecraft] What crystal filter do you use the most? In-Reply-To: <56096C08.2020206@blomand.net> References: <56096C08.2020206@blomand.net> Message-ID: Again and again, we all encounter signal conditions where a very weak wanted signal is close to a very loud unwanted signal. For this the best filter setup is where BOTH the roofing and the DSP filters are at the desired operating bandwidth. That is why for CW contesting, in pure self-defense, the 400 and 250 8 pole roofing filters are defined as 450 and 350 respectively. 450 is a "running" bandwidth for 500 Hz separation that recognizes that many answerers to our CQ's do not have the ears for getting close to frequency. When up and down loud signals get too close, dropping to 350 Hz width and using shift will help enormously without losing too much of the space for up and down callers. Additionally, I make sure that the filter offsets are set so the minus 30 dB points of the two filters coincide. The desired effect is that when you tune away from an unwanted signal, at the passband edge it falls off like a ball slowly rolled off a table. This procedure finally made the K3 selectivity as sharp as my MP with the Inrad 8 and 455 filters. One does NOT have to treat the roofing filter as if it is not involved in selectivity. Quite the contrary, as when a certain 40m Italian station is 35 over 9 up 350 Hz and I am being called by a QRP station using a wet noodle antenna on his basement floor, who is well down in the S2 noise, who also insists on adding /QRP to the end of his call. This becomes more and more important as these RX improvements keep shrinking what we thought was incoming noise and we hear ever weaker signals. Turning the edge of roofer plus DSP into a knife is VERY useful. 73, Guy K2AV On Monday, September 28, 2015, Bob McGraw - K4TAX wrote: > Ken makes a pertinent comment; "the DSP does all the rest".

The 400 Hz filter as it works well for both CW and RTTY. If I were not so concerned about RTTY, I would consider the *INRAD* 500 Hz (8 pole) filter for CW along with the 200 Hz (5 pole) Elecraft filter for times when adjacent signals are just too strong (I already have the 200 Hz filters). For SSB, I believe the stock 2700 Hz is more than satisfactory. The improvement from the 2800 Hz [8 pole] filter does not justify the "exchange price" - the savings from sticking to the stock 2700 Hz filter can be used for the 400 Hz CW filter or to *add* either an 1800 Hz or 2100 Hz "narrow" SSB filter if needed. 73, ...

Message-ID: <5609968C.8030408@aol.com> I'm with W4TV on the 5-pole 200 Hz filter as my overall go to on close in CW sigs. The 8-pole 250 Hz filter, which I also have, is actually about 350 Hz in width and way too wide for me. That said, I use either a 500 Hz or 400 Hz filter most of the time on CW/RTTY It is unfortunate that Elecraft no longer makes the 200 Hz filter. Shame. If I was going to get only one CW filter, it would probably be the 400 Hz jobber. 73, Dan From jim at audiosystemsgroup.com Mon Sep 28 16:19:58 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 28 Sep 2015 13:19:58 -0700 Subject: [Elecraft] Grounding In-Reply-To: <003101d0fa1b$3176bab0$94643010$@gamewood.net> References: <56096CC3.4060106@audiosystemsgroup.com> <003101d0fa1b$3176bab0$94643010$@gamewood.net> Message-ID: <5609A0EE.1000802@audiosystemsgroup.com> On Mon,9/28/2015 11:26 AM, Kenneth Talbott wrote: > Several years ago the NEC relaxed the requirement that safety ground and > neutral be connected at only one place.

Thanks Ian. I don't have a full copy of Acrobat that I can put on this computer, so I use Libre Office or Open Office to generate pdf files. Those programs only generate pdf files with slides, one to a page. When I was still in biz, I bought full Acrobat and put it on my working computer. That did allow me to print multiple slides per page, and I used it a lot. There's another issue with printing -- the background color for the slides, which burns a lot of ink. The roots of this Power Point are quite old, before I realized the printing issue, and it's a LOT of work to change because many of the slides are complex, with lots of labels inserted to make them visible at the back of the room. 73, Jim K9YC From drewko1 at verizon.net Mon Sep 28 16:44:44 2015 From: drewko1 at verizon.net (drewko) Date: Mon, 28 Sep 2015 16:44:44 -0400 Subject: [Elecraft] Best way to make comparative antenna signal strength measurements using K3 (and P3) In-Reply-To: <016601d0f9fb$7c26a7c0$7473f740$@com> References: <016601d0f9fb$7c26a7c0$7473f740$@com> Message-ID: <5609A6BC.5070400@verizon.net> Well, this is not quick and dirty, but FWIW... WSPRnet is great for antenna comparisons. Write a script to switch your K3 between the two antennas at frequent known intervals. Run it over the course of days or weeks and you will have literally thousands of signal reports which, if you know what times each antenna was switched in, you can compare as you like in a spreadsheet. Compare signals strengths; number of stations worked with each antenna; geographics areas, band performance, etc. I did this when switching from an outdoor antenna that I would soon have to take down to a multi-band indoor antenna, wondering what deficit the indoor ant might have on various bands and how much increase in power I might need to overcome it. (I had a K3/10 at the time and was considering the 100 watt PA). Anyhow, you can't beat WSPR for antenna comparisons. 73, Drew AF2Z On 09/28/15 10:39, Bill Conwell wrote: > I'd like to do some quick and dirty comparing of antenna output signals > using my K3 (and/or P3). > > > > (I've got two antennas I'd like to compare using different received carrier > signals - e.g., from a neighbor's TX, W1AW RTTY bulletins, etc.) > > > > I see that the K3 can display the RMS value of receiver AF output (mVp-p), > unaffected by AF GAIN control.

So I asked him and he said that under certain conditions the NEC does allow grounding the neutral wire in an outbuilding. In my case, he is not doing that in my outbuilding. He says it is always better to tie neutral and ground only at the service entrance if possible.

Objectionable neutral current presents a real danger and can damage equipment as well as cause fires and electric shock or electrocution."

The only "remote panel" in which a bond would be permitted between neutral and ground is one in a second building where ground is not carried between buildings, or when the remote panel is for a "separately derived system." A system is separately derived when fed by a transformer.

Message-ID: <41ADAD95-5D62-480B-92EC-039062BA15D0@me.com> Does anybody have a ?worked example? of how to use the L and C values reported by the K1 internal antenna tuner to analyze an antenna? I feel pretty guilty asking this, because it?s sort of a ?please help me do my homework? question. And I am supposed to know how to do this homework. :-) I have a space-limited dipole for 20 meters with drooping ends. The KAT-1 tuner will tune it. What I want to know is whether to use a 4:1 or 1:1 balun, or no balun, at the antenna. If the tuner reports 24 ?x10? pF, is that 240 pF or 2.4 pF? A straight reading suggests that it?s 2.4 pF, but I don?t see how the tuner circuit can provide so little capacitance. But C4 (82 pF) plus C5 (150 pF) gives 232 pF which could 240 pF if you include some parasitic capacitance, maybe? Next, I need to figure out the circuit. If the tuner reports nt 2, I think that means that the coil is next to the tuner?s antenna connector, and the capacitance is in parallel with the radio connector.

That is if and only if the KAT1 tuner has tuned to an SWR=1. To figure the impedance at your antenna feedpoint, you will have to know the type of feedline as well as its length and feed that information into the formulas or an application such as TLW - (transmission line for windows). The easier way is to beg, borrow or steal an antenna analyzer and measure the impedance at the shack end of the feedline. You will still need to apply the feedline parameters to determine the antenna impedance, and the feedline will act as an impedance transformer. BTW, 24x10 is 240pF. 73, Don W3FPR On 9/28/2015 7:37 PM, Douglas Hagerman wrote: > Does anybody have a ?worked example? of how to use the L and C values reported by the K1 internal antenna tuner to analyze an antenna?

Even a low dipole will have a feed point impedance of roughly 75 ohm, so 1:1 would be fine with coax. You may want to consider a current choke at the feed point, but that's up to you. With 450 or 300 ohm ladder line, a 4:1 would be more appropriate to match the feedline to the expected impedance of the K1 input. > If the tuner reports 24 ?x10? pF, is that 240 pF or 2.4 pF?

While 'common logic' will say to match the antenna to the line impedance, that 'common logic' is flawed. It certainly will be that a good common mode choke is all that is needed at the antenna feedpoint, and that is a 1:1 impedance transformation. Its purpose is to keep common mode currents off the feedline and to keep the real radiation confined to the antenna. That aspect is unchanged no matter whether the feedline is 50 ohms or 600 ohms. The feedline will act as an impedance transformer no matter what (unless the feedline is exactly matched to the antenna feedpoint impedance). Keep in mind that open wire transmission lines are low loss (that is important). If you connect a 600 ohm open wire transmission line to a 'resonant' dipole having a nominal impedance between 50 and 75 ohms, that transmission line (even thought it has an SWR between 8 and 12) will have extremely low loss. 450 ohm ladder line and 300 ohm ladder line are similar, but will have higher loss than open wire line. The real problem is to match the impedance of the shack end of the feedline to 50 ohms. The transmission line will act as an impedance transformer, and depending on the length of the feedline and the frequency, the shack end may be vary between a very low impedance and a very high impedance. In other words, attempting to use a 4:1 balun or a 1:1 balun (or any other ratio) at the antenna feedpoint may be an exercise in futility. It all depends on the feedline impedance transformation at the frequency of interest. And that depends on the feedline length and the frequency. One would use a 4:1 balun to match coax to an antenna feedpoint impedance of 200 to 300 ohms (folded dipole) or to a properly tuned OCF antenna, but for all other conditions, all bets are off unless you know the antenna feedpoint impedance of the antenna at all frequencies where you want to use it. A study of the ARRL Handbook or ARRL Antenna Book section on transmission lines should provide you with more information. 73, Don W3FPR 73, Don W3FPR On 9/28/2015 8:02 PM, Byron Servies wrote: > On Mon, Sep 28, 2015 at 4:37 PM, Douglas Hagerman > wrote: > > With 450 or 300 ohm ladder line, a 4:1 would be more appropriate to > match the feedline to the expected impedance of the K1 input.

So it has to be coax, and as you say, the ideal situation would be to have a balanced signal at 50 ohms at the antenna, connected to the coax, which would not be acting as a transformer because of the good match at the antenna end, and then feeding into the tuner which would say ?good, it?s 50 ohms of resistive impedance at this end!? and not do anything.

I 've used them for several all band antenna's, horizontal and vertical, and they have worked quite well for me. Here is a link to some interesting and thorough explanations and suggestions from SGC about various types and considerations regarding all band antenna's incorporating a remote tuner at the antenna feed point. http://www.sgcworld.com/technicalInfoPage.html A somewhat less expensive remote tuner is the GC-3000. (I read somewhere that this is the same as the MFJ remote tuner, but I'm not sure about that.) I own one of those and it works almost as well as the SGC tuner. It just doesn't seem to have quite the matching range as the SGC tuner. This means you might have more band segments with a 1.5:1 or 1.7:1 match instead of a 1.1:1.

Message-ID: <201509290643.t8T6hgu5019737@mail40c28.carrierzone.com> Bob, Good comments. I think those of us who have been in ham radio for many years still think of physical filters as doing the job of specifying the radio bandwidth and forget that today's radio often is digital or partially digital where DSP does the job and filters are only used supplementary to help reject off frequency interference. I have the 13-KHz filter for FM and can be used for AM which I only would use for sw bc where the KBPF3 operates. the 2.8-KHz filter serves 95% of my use even for CW. The exception is working CW-eme where I typically operate the DSP at 100-Hz. There the 400-Hz roofing filter helps improve overall noise rejection and maybe helps sensitivity by deepening the off freq skirts (a guess). I have no local QRM on eme. I typically tune eme in wide bw until a signal is detected by digital waterfall display which I then tune in and reduce bw to hear the signal. My sub-Rx only has the 2.8-KHz filter because I only use it for diversity using digital modes or SSB. But it took me awhile to get my mind to accept that Rx bw is done by the DSP and not the filters. PS: my new SYN3A and KBPF3 mod kit arrived in the mail today. Going to be interested to see if I see any improvement in Rx sensitivity on eme.

I'm guessing that X10 means just that; whatever value displayed x10. If you can do the parallel/series math to derived the Z looking back into the tuner then go here: http://ac6la.com/tldetails1.html and down load the program. This will do the transformation for you for the coax cable. Just be sure to get the direction correct. (R & X at the input) Once you have the antenna Z determined, you can use these values for the load and change the length of coax and see what you get. Remember that the first answer is the conjugate of the antenna Z. Regardless, use a 1:1 current balun.

A straight reading suggests that it?s 2.4 pF, but I don?t see how the tuner circuit can provide so little capacitance.

If the tuner reports nt 2, I think that means that the coil is next to the tuner?s antenna connector, and the capacitance is in parallel with the radio connector. I guess that is designed to be 50 ohms of pure resistance, so I have a nice little circuit with one of each part.

In theory, all of this should tell me the antenna's impedance at the point where the balun connects, which should suggest whether it would be better to use a 1:1 balun instead. > > Does anybody have an example of this sort of calculation?

I didn't want to deal with offsets or aligning filters when I eventually get the sub RX. Because of this I opted to upgrade to the 2.8KHz and purchased the 400Hz on this list. When I get the sub rx I'll buy 250Hz x2, and duplicate the filters in the main rx. My I ideas (which may be wrong) are to strongly leverage diversity rx (two separate antennas and receivers). I was planning to get the P3 first but I'm using a poor man's Panadapter (SDR and HDSDR software which works very well. I'm not sure what the P3 will do for me at $700 that my current setup won't other than look nice and allow pc-less operation. I use HRD for logging anyway so... (shrug). I've found under normal use with the filters not configured the receiver works really well. Where the filters seem to matter is when trying to hear weak signals near VERY close and strong signals. Even without the filters it's copyable after some fiddling. The filters make it easy for me. Play with the rig and learn all the buttons and features. While waiting for the new K3S book to come out ( to be released soon enough so I pre- ordered/paid) I went ahead and bought the current K3 book and it's answering most of questions.

Seems, that is still, huge confusion about that, so i will try to formulate a problem on simply way: *With low impedance earphones plugged into the audio jack on the K3, you can hear a really annoying noise (hiss) even with the AF and RF volume set to zero(CCW). This audio hiss has a constant level, is added to the audible RF noise and can prevent one from hearing weak signals on an otherwise quiet band.* That hiss has nothing to do with K3 receiver or settings - simply is permanent present. This indicate that something must be wrong with earphones amplifier LM4811MM, and that is odd, because LM4811MM seems to be an high quality chip, designed exactly to work with low impedance earphones , with a minimal amount of external components? My question is: is, in the mean time, known any hardware (or anything else) modification for that issue? best regards, Bozidar -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-background-hiss-noisy-K3-update-tp7608490.html Sent from the Elecraft mailing list archive at Nabble.com.

Message-ID: <560ADFAF.9040105@aol.com> To answer a few questions, I'll try to be as definitive as possible. I see, according to both the P3 TX Mon AND the LP-100A up to about 0.4 watts output from the K3S on CW mode in TEST. The sensors for both the TX Mon and the LP-100A are in series, the TX Mon immediately after the K3S and the LP-100A through a short piece of RG-400. If I substitute the K3 for the K3S, there is no indication on either "wattmeter." So methinks that this proves an issue with the K3S. Also what is interesting is if I monitor the K3S signal (while in TEST mode) on the K3, the signal level pins the meter on the K3. Reverse (the K3 transmitting in TEST MODE to the K3S), it's about S7. Not a great test, but significant I think. It's almost like a short spike of power is output (as indicated on the P3 TX Mon and LP-100A). I contacted a local ham but he cannot hear any transmitted signal (he's about 7 air miles away), but methinks it's a spike of such short duration or generation that he wouldn't. I am also seeing an anomaly with the K3S that I have yet to fully understand and as far as I can tell happens only on 80M. I run SO2R and have bandpass filters between the K3S and K3 and their respective amplifiers. On 80M, and according to the internal K3S wattmeter, I have a 1:1 swr going into the bandpass filter but as soon as the rig output is set to above 12 watts, i.e. the KPA3A kicks in, the SWR immediately rises to 5:1. The SWR remains high until I increase the power up to about an indicated 45 W output (by virtue of the power control on the K3S), then the SWR immediately reduces back to 1:1 and remains there to max power output. Of course the "real" power output is cut back until the SWR goes down. So, you say, it's the bandpass filter. Perhaps, but I have swapped bandpass filters and the problem remains with the K3S. I have also eliminated the amplifiers by installing a dummy load in their place. I did this to make sure the KPA3A was not transmitting a dirty signal on some other frequency against a resonant 80M antenna. Same issue. There are no issues with the K3 in line - it's only the K3S.

You did not mention the S/N range of your radio, and I may be incorrect about this but I think that very early K3's had an issue similar to this, that was quickly resolved. The S/N of my K3 is in the 58XX range, and I have never heard any of the hiss that you describe. I have a pair of Grado SR225e headphones that have an impedance of 32 ohms, and are very sensitive. I plugged them into the Phones jack on the front of the K3, and with the AF gain control turned fully CCW, there is no hiss or for that matter any sound at all. It's possible that there is an issue with your AF Gain control/encoder. You might want to use the built-in test that allows you to check the encoder steps of the two AF gain and two RF gain controls that is available from the CONFIG > SW TEST menu on the radio. This requires that you first make sure that "Tech Mode" is enabled. To do so, go to CONFIG > TECH MD and then turn your VFO-A dial so that "On" shows above TECH MD on your K3. Then, rotate your VFO-B dial to navigate over to the "SW TEST" menu option. Then slowly rotate your AF Gain control on the K3. You should see the encoder steps (visible on your K3 display) increasing in number as you rotate it clockwise, and decreasing in number as you rotate it CCW. In my case, rotating the AF Gain control fully CCW shows a step of 2. If your value is higher than that at fully CCW, perhaps your AF Gain encoder has a problem. 73, Dale, WA8SRA > Hi, > i have studied all the posts about this topic. > Seems, that is still, huge confusion about that, so i will try to > formulate > a problem on simply way: > > *With low impedance earphones plugged into the audio jack on the K3, you > can > hear a really annoying noise (hiss) even with the AF and RF volume set to > zero(CCW).

I've had the same hiss on my K3 audio since it arrived from the factory. I've used a wide range of headphones, expensive and cheap, and it's present with them all. I discovered that the fix is to introduce some resistance into the audio line and I use a very small, outboard, stereo headphone volume control to do this. I bought several for a few dollars on eBay. I just dial in a very small amount of resistance(I've never actually measured how much) and the hiss is completely gone, with only a very small effect on the K3 audio volume which can be easily compensated for by a tiny increase in the AF gain control if you need to. I have the same hiss on my KX3 audio, which I manage in the same way. FWIW, I have no hiss at all using the same headphones on my little KX1.

I have a horrible intermittent noise that I cannot identify and is heard state-wide at the upper portion of 80 m. I?m hoping a small loop antenna might help null that noise or at least a lot of it. I know I want a small loop. Well, maybe... I have looked at small shielded loops, small shielded mobius loops, mag loops, etc. I have a friend who came by and once recommended that I string up a random length loop around the top of my wooden privacy fence. Some of the privacy fence needs to be repaired and/or replaced. The height of the fence is about 6? and I could come down 12 - 16? from the top of that and run screw-in ceramic insulators. Except for the portion that?s my house, the privacy fence runs the perimeter of my back yard. I could use this on 160 m if I don?t use a preamp or have the preamp switched out. Whichever route I take, I?ll probably use the small preamp from Kits and Parts at the input of the antenna. I have access to solid conductor LMR-400, I even have about 40? of 7/8? hardline, but I want something that?s not real cumbersome. I think the mag loop may be easier to construct but none of the small loops look extremely difficult. I am, however, a tad confused on how to couple a shielded loop to the preamp. Can I just use alligator clips and run those to the shield and both conductors? I don?t see why I could not connect a preamp at the input to a mag loop. I could take the mag loop portable with me if I wanted. I?m just looking for some advice and if y?all think this is too far off topic, please respond directly.

There was a ham I knew that kept complaining that his AD9850 DDS module was operating on two different frequencies, sometimes at one frequency and sometimes at the other. I could not convince him that this was a result of aliasing WITHIN THE SCOPE itself. He bought additional DDS modules, surprise! They did exactly the same thing. Then, he bought an old analog scope and no longer saw these problems. I do have and use a USB scope "in the field", but I am careful to understand what that scope is telling me. I also have a couple of analog scopes, one on the bench, and one portable. I can verify questionable results with them. 73, Terry, N4TLF -----Original Message----- From: James Bennett Sent: Tuesday, September 29, 2015 5:31 PM To: Elecraft Reflector Reflector Subject: [Elecraft] OT USB Scope Question A bit off-thread, but sort of related - wondering if folks on this reflector have any experience with USB oscilloscopes.

Message-ID: On my K3 I have an LP-Pan connected to my IF out on the main receiver and a FunCube Pro on the subreceiver IF out. The LP-Pan is setup to a Steinberg USB UR22 sound card. Therefore, I have two panadapters, one through Win4K3 for the main receiver, the second using NAP3 v5 to the funcube pro. This give full spectrum display. I say this, because my normal operating mode with SSB is 2.8k hz and CW 250 hz dialed down to 50 hz. I play with RTTY in FSK mode at 300-400 hz. I my main receiver I have 13k hz for FM and AM, 2.8k, 2.1k, and 250k. In the sub receiver I have 2.8k only. During some DATA A modes using other digital software, I may adjust the filter settings from 3k down. CW Skimmer is setup to ready the main receiver, so it has 192khz decode. Even during contests I usually keep my SSB filter settings at 2.8k and cw at 50 hz.

The SWR calculation gets confused when both forward and reflected power are zero. In the next code release I'll add a feature to force the SWR to read 1:1 when forward power is close to zero.

Simply blank the display or show "N/A". Most QRPers understand that primitive SWR meters may display "zero reflected power" due to the diode threshold voltage, but we'd hope for the P3 to be a little smarter. 73 from Ian GM3SEK From john at carltonhouse.eclipse.co.uk Wed Sep 30 03:59:50 2015 From: john at carltonhouse.eclipse.co.uk (John Lemay) Date: Wed, 30 Sep 2015 08:59:50 +0100 Subject: [Elecraft] No power out and no receive In-Reply-To: <1443585137986-7608527.post@n2.nabble.com> References: <1443583798650-7608524.post@n2.nabble.com><1443584968979-7608526.post@n2.nabble.com> <1443585137986-7608527.post@n2.nabble.com> Message-ID: <2BE35AA72EB74B1D989DDCB8D4331976@OwnerPC> If there is no receive capability at all on the radio it could be quite a serious fault - either with the radio or the feeder or aerial.

When BAT is selected, the MCU samples the voltage produced by the R6 and R7 voltage divider. When ATTN is to be indicated, the MCU pulls pin 3 to a low state which turns on the LED. I suspect you are seeing the result of brief negative going pulses between intervals when the voltage is sampled at the MCU pin 3. I do not see any evidence of that behavior with a 13.8 volt power source, but I suspect it may become evident with a low supply voltage. As you indicate, it should not be a big deal, but is only "interesting behavior". 73, Don W3FPR On 9/29/2015 11:20 PM, ron hansen wrote: > Just finished receiver portion of build on unit ser no 3388.

Also the signal level on 80m will probably be pretty good without an amp. I suggest that you built an unshielded loop with a piece of wire and a tuning capacitor. Say a diameter of 5 ft. Then, you rotate the antenna by hand and see whether the noise is nulled and whether the signal strength is sufficient. My shielded loop on 160m was a disappointement as it did not pick DX well.

I'd do a little online hunting for features and reviews that would best fit my use cases. Just a quick glance at the range of devices available in the PicoScope range shows everything up to 12GHz bandwidth, 16bit sample sizes and many inputs. Many also have signal generators built in, which could make testing filters/traps/etc. a snap. I'll share one interesting thing I was told by a representative of one of the manufacturers at a show. I was talking about the performance of the devices they were exhibiting and the possibility of getting the raw digitized data into my own code. While that was suggested to be possible, when I said I was considering trying it as the front end to an SDR he pointed out a significant problem. He pointed out that the A/D in the USB scope box ran too fast for USB, so the computer doesn't get all the data, just bursts of signal. That works perfectly for a scope which by it's nature doesn't display everything but would be useless for SDR.

Check the TMP cables that connect the KREF3 to the KSYN3 and to the K3 RF board to make sure they are all properly seated. If your K3 has the newer KSYN3A synthesizer board (mounted on the front panel shield with the KREF3) you should see a green LED glowing brightly when you look down from the top (it's on the back of the board near the top edge). If it's blinking the synthesizer is NOT locked and will produce the symptoms you are experiencing.

The better choice for portable ops is similar to what you called out. For hiking, I use a Think Tank strobe bag and it handles the same "backpack load" you listed. I even bought a second one as a battery companion carrier, for the main LiPo external battery pack (using the internal AA cells as emergency reserve). The ammo box allows generous amounts of space for the KX3, KXPD3, MH3, 2m telescoping antenna, ear buds, BNC adapter and antenna wire kit, etc. I placed a washcloth in the bottom to pad the KX3's surface from the somewhat rough interior of the box.

The more sensitive the headphones means it takes less audio power to produce acoustic energy. If a given signal say a value of -25 dBv is applied, this signal may be heard with some headphones and may not be heard with others. Now, adding a series resistor in effect reduces the apparent sensitivity. In fact, it reduces the available power to the headphones. In the case of the -25 dBv signal, adding a resistor may reduce this value to -35 dBv, or below the sensitivity threshold of the headphones. All of this has little to nothing to do with the impedance of the headphones. In most instances, everyone's hearing decreases with age. Other factors that affect a diminished hearing is prolong exposure to noise or any loud sounds. A combination of sound level and time exposed are key elements to diminished hearing. Repeated exposure over a long period or repetitive cycles will lead to permanent hearing loss. And in many cases this loss is so gradual over a period of years it is not realized or acknowledged to exist. From my experience, the audiologist, after a hearing test said my hearing was normal. Now what he didn't say was "my hearing was normal for a male of my age". My wife complains that I don't listen to her. At least that's what I think she said. 73 Bob, K4TAX On 9/30/2015 7:57 AM, Sullivan, Mike C wrote: > Not sure this helps much other than knowing you are not alone. > I have had the same problem and fixed it exactly as John - VK7JB has - SN on my K3 is in the 800s. > I have checked my S/N ratio and it is at least as good as the spec. > My hearing has been checked here at work and I have been told that I have good hearing for anyone these days, and really good for an OF. > I would bet having a pair of good ear-plugs in my pocket from the age of 18 or so had a lot to do with it. > Just tripped 60 yesterday.

When BAT is selected, the MCU samples the voltage produced by the R6 and R7 voltage divider.? When ATTN is to be indicated, the MCU pulls pin 3 to a low state which turns on the LED. I suspect you are seeing the result of brief negative going pulses between intervals when the voltage is sampled at the MCU pin 3. I do not see any evidence of that behavior with a 13.8 volt power source, but I suspect it may become evident with a low supply voltage. As you indicate, it should not be a big deal, but is only "interesting behavior". 73, Don W3FPR On 9/29/2015 11:20 PM, ron hansen wrote: > Just finished receiver portion of build on unit ser no 3388.

The Base of the MD-100 Mic takes the same type connector as the MIC input on the front panel. There may be a few options for you. 1) Consider wiring the Element of the MD-100 through an 8-pin connector to a 1/8" phone jack to the rear panel of the K3. Leave the MD-100 base plugged in and use the PTT on it. I 'think' that will work. 2) As 1) above plus wire an RCA plug to a desk, or panel mounted switch. Plug that into the rear PTT jack on the rear of the K3. There are some nice, fair sized bi-position switches that can be used. One position is momentary contact, while held in place. The other is locked in place until disengaged. ON-OFF-MOMentary. In this case, the MD-100 Base wouldn't need to be plugged into the rig. 3) Extending the fixed cable on the MD-100 base that goes to the MD-100 mic may work as well. That may be achieved by splicing in additional length of cable or an extended cable with an 8-pin female connector on one end and a 8-pin male on the other end. 73, Dick - KA5KKT "I use a Yaesu MD100 desk Mic with my K-3.

It may be a good idea to read the firmware release notes and make a notation in the manual when changes like this are made. 73, Don W3FPR On 9/30/2015 3:43 PM, Steve Mollman wrote: > I have a K3 without the sub-receiver.

Right. But there may be some difference in where the transmitter's chassis was connected. When there's common mode current on a feedline, that connection becomes part of the antenna. > As far as the buckmaster ocf, it uses a current transformer > (auto-transformer )to balance the antenna and match the impedance. Don't believe everything you read! OCF antennas are notorious for putting common mode current on the feedline.

As to why one radio does it and one radio does not, something is different in your system. Make sure each piece of equipment is tied {bonded} to a common point for your station. In my case, I use the power supply ground terminal as the common point. Also, since you have swapped radios around, highly suspicious would be coax jumper cable being defective or a PL-259 not being tight. I always snug my PL-259's with a pair of 4" Channel Lock pliers. With some brands and manufacture of connectors, finger tight is not good enough. 73 Bob, K4TAX On 9/30/2015 2:51 PM, Jerry Moore wrote: > What I don't understand is my previous radio didn't affect the TV as far as I know (xyl never complained) so it has me perplexed because the radio shouldn't matter.
