I didn't see mention of the K4 version of the K3EXREF or the high stability TXCO for the k4. Maybe it's included? Now to sell some un-needed things, An up to date K3, an Icom Pro, old Corsair II, Al-1500, Some 3CPX800A7 pulls I never needed to use with my old Ten Tec Titan, an unused Pixel loop & much more will go. All in all, I'm going to be thinning my excess load that I've been promising I'd do. Do a good thing and everything has multiple positive reactions. This is going to be a fun learning curve. 73, Gary KA1J From k9jri at mac.com Sat Jun 1 07:09:24 2019 From: k9jri at mac.com (Michael Blake) Date: Sat, 1 Jun 2019 07:09:24 -0400 Subject: [Elecraft] Digital Voice Plans?

Modes such as C4FM, Dstar, FreeDV, etc?.. If none do you have any plans for freestanding DV modem hardware that would allow HF DV on the K3s, K4 or any other manufacturer?s HF SSB transceivers?

When in TX all I see is one bar on the rf out meter, 0 ALC. Upon return to my summer home in NJ I started up my K3 which was on remote duty for the winter. All is working well except the USB audio CODEC TX. This all was working when I left. At first I expected the new version of WSJT X, but I'm having the same problem with another application. I went through the KIO3B install manual and everything is set correctly. I'm running K3 firmware level 5.67, which I also updated to assure no issues with the same version that was already installed. I uninstalled the USB drivers and let the system re-install. I'm not experiencing any normal SSB TX issues, the K3 transmits TX audio fine in SSB voice mode.

Even if it were true (that the K4 favored right handers), that wouldn't be a disadvantage to me, and I am very left handed!! I've almost always favored setting up my radios on my right side, and operating the controls with my right hand. My left hand is then free to either write, send on my paddle, or whatever! Now, I do have the ability to do certain things right handed, but not the kind of things that require great precision. I even play golf right handed, and bat right handed in baseball, but that is more a matter of how I was taught and the equipment available. I've often thought I should learn to send CW right handed, but never have done it. I can run an adding machine right handed, but again that was almost forced on me by the design. In short, I don't know why people want to rely so heavily on their dominant hand. It really is inconvenient to do so. Controlling a radio with your "opposite" hand can't be that difficult a task, and the benefits of doing so are many.

Our early testers are saying it's as good or better than anything else they've used, removing stochastic noise without the characteristic "hollow" sound of earlier algorithms. In my own tests, I'm finding weak SSB signals I simply couldn't copy without it. It goes beyond just reducing listening fatigue.

I rarely use the offset but do often use the VFO B when in a pileup and I want to move away from someone who just started calling on my calling frequency. For me, with the K4, I would much rather see the offset knob be exchanged with the now higher, VFO B as it will require me to lift my arm & wrist where if it were at the bottom, I could maintain the same ergonomic position. In a contest or long day at the radio, extra motions become uncomfortable over time. Maybe it's possible for the two knobs to be optionally switched in the configuration options? 20 years ago it wouldn't have mattered to me either way. After an immortal youth with Karate, motocross accidents & sports injuries, time eventually does have its way with us. 73, Gary KA1J > My thoughts on gandedness: > > My complaint about most Radio?s is placement of phone and mic jacks > on front panels adjacent to control knobs.

If the K3 is on and you spin the big knob while using the KWM2, the KAT will respond to the K3?s QSY. If you change bands on the K3, BOTH the KAT and the KPA will also change bands. And (most strangely), if you power off the K3, shortly the KPA will switch to 60 meters. The latter occurs because the K3 pulls the band lines up to internal Vcc (0V when power is off), which is the combination for 60 meters. In other words, leaving the aux cable connected from the K3 to the KAT and KPA may have some unintended consequences. The best description for connecting multiple transceivers to the KPA500/KAT500 combo is in Fred Cady?s book ?The Elecraft KPA500 Amplifier and KAT500 Tuner". You might want to refer to it when setting this up. 73!

The AUX buss is connected in the K3S configuration.? The Eagle has only the RF coax to the A / B switch as does the K3S.? There is also an AMP KEY line from the Eagle to the KAT500.? {See Fred Cady book on this point.}? This assures the Eagle when in TUNE mode does not activate the KPA500 as the PTT line is opened in the KAT500.? I can switch radios without any issues.?? However, If I choose to use the Eagle, the K3S must be OFF.?? Otherwise the system is seeing and responding to the frequency of the K3S VFO supplied by the AUX Buss.???? When using the Eagle, the Amp and ATU respond to the applied RF. Thus.......only one radio at a time is powered ON.? This also prevents transmitting into a dead short thus from having the A / B switch in the wrong position. With this configuration, the KPA500 and the KAT500 will switch bands and resolve a match automatically. But......you must understand the station you wish to use must be ON and the other station OFF.????

In-Reply-To: References: Message-ID: Jim, Yes, the K2 limits the power in a HI CUR condition. First your DC voltage is low. Check the power cable and make certain all connections are tight - I recommend #16 wire for the power cable, but #18 should be OK. If you are using something smaller, change it to the heavier wire. If your power supply is adjustable, increase the voltage to at least 13.8 -- 14.5 volts is even better. A 4 to 6 amp regulated power supply will be adequate for the base K2. Does this Hi-Cur condition occur on all bands? Or only 40 meters? If only 40 meters, did you wind the 40 meter Low Pass Filter inductors as indicated in the original manual? Or did you wind them from a more recent manual? Check the number of turns - yours should have 16 turns on both L25 and L26 unless you altered the capacitors in the 40 meter LPF to correspond to the newer configuration with 5 capacitors. Normally a Hi Cur along with low power problem says there is a problem with either T4 or the LPF. T4 should be wound with the 2:3:1:1 ratio. While it can be wound with a 2:2:1:1 ratio for better efficiency at 5 watts and below, that is for CW only, and the efficiency will be less above 5 watts - and should never be used with the KSB2 option or the KPA100 option installed (or any external amplifier). When counting toriod turns, count the number of times the wire passes through the center of the core. 73, Don W3FPR On 6/1/2019 2:48 PM, Jimithy66 wrote: > Am in final testing of a K2 Ver.A kit and transmit output > will not go above 2 watts on an external power meter > and 50 ohm load when keyed or pressing Tune. > > "Hi Cur" flashes briefly and power is limited to 2 watts > Display....E = 11.9 and I = 2.0 Keyed (Un-keyed I=0.22) . > > Any idea where to start looking ? > From eckerpw at gmail.com Sat Jun 1 16:30:17 2019 From: eckerpw at gmail.com (Paul Ecker) Date: Sat, 1 Jun 2019 16:30:17 -0400 Subject: [Elecraft] KAT Problems Message-ID: Bob- I tried doing the procedure just as you described, it works fine on all bands except 40 and 160.

Rotating the knob does nothing. A second tap shows RF --58 momentarily and then returns to VFO B, 2.

When I send CW I hear a side tone from the headphone and the speaker when the headphone is unplugged. 4. When I HOLD the AF/RF-SQL knob and go to MON the OFS/B window show 5 and rotating the AF/RF-SQL knob does not change the number. 5. The PBT I/II knob appears to function properly. 6. With MODE set to USB rotating the Keyer/Mic knob does not produce any indication of a change in MIC gain in the OFS/B window. When in the CW mode rotating the know does not change keyer speed (remains at 18 WPM), 7. When I HOLD the KEYER/MIC knob to adjust power 5.0W is displayed in the OFS/B window.

Right. I've never used an AUX cable between any of my Elecraft gear, only the keying interrupt lines (as RCA-RCA cables). Frequency detection in the tuners and amps is plenty good enough to switch near instantaneously and call up memorized settings. A dit or a bang on the mic is more than enough. What IS needed is to either switch the keying interrupt line or loop it through both amps, depending on the keying logic for the other amp. 73, Jim K9YC From donwilh at embarqmail.com Sat Jun 1 17:12:17 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sat, 1 Jun 2019 17:12:17 -0400 Subject: [Elecraft] KX3 Receive Audio & Control Knob Problems In-Reply-To: References: Message-ID: Robie, Either you have a KX3 problem or you are not tapping the knobs correctly. Do you have the KX3 manual? If not, download it from the Elecraft website and read through it. If you need more comprehensive and detailed information along with exercises, you can order the Fred Cady (SK) manual from Elecraft. For firmware updates, you will need the KXUSB cable which you can order from Elecraft. As an alternative if you have an RS-232 port on your computer or you have a USB to RS-232 adapter, you can build the KXSER cable - the schematic is in the Elecraft XG3 manual near the end. You will also need to download the KX3 Utility from the Elecraft website and install it on your computer. 73, Don W3FPR On 6/1/2019 4:43 PM, Robie Elms wrote: > All, > > I have acquired a used KX3 (serial number between 4000 and 5000, uC > firmware 0.150, dsp firmware 01.21) and I am checking it out.

Don't assume you are doing anything wrong. I have already reported (and Elecraft has confirmed) one KAT500 firmware defect that prevents selection of an enabled antenna. Maybe you have found another case.

That is helpful information - the Field Test K2s (SN 100 or less) are a bit different than the Rev A K2. There should be only one diode from Q18 gate to ground. The anode connects to the gate and the cathode to ground. While the VFO/ALC mod is a benefit, it will not produce any change in the S-meter. As for the S-meter problem, determine if it is an LED display problem or a problem with the actual S-meter circuit. Rotate the RF Gain control from full clockwise slowly to the CCW position. If the LED display is working, you will see the S-meter indication increase. If it does not, you have a display problem - reflow the soldering on the LED bargraph and Front Panel RP2, then check again. 73, Don W3FPR On 5/31/2019 9:42 PM, Mike Short wrote: > I recently bought a used K2/10 and the S-Meter does not work.

I'm wondering how we are to connect a paddle via the remote (or a mike)? With the K3/0 it's a plug and play thing using the RRC boxes. But since the K4 works directly over the 'net just wondering how to actually transmit. I also wonder if there is a way to connect a P3 to the K4? If this were possible, one could monitor visually a larger segment of a band with the P3 while using the built-in monitor to see a smaller segment in more detail. 73, Art KZ5D From billamader at gmail.com Sun Jun 2 13:00:02 2019 From: billamader at gmail.com (K8TE) Date: Sun, 2 Jun 2019 10:00:02 -0700 (MST) Subject: [Elecraft] Handedness In-Reply-To: References: <1949442452.7084373.1559286996847@mail.yahoo.com> <16DBCAE160E8405FBACB71D0DF6F5E02@LAPTOPEPVQLR1I> Message-ID: <1559494802606-0.post@n2.nabble.com> GM Bill, K3_EZ, Win4K3, and I believe N4PY's software allows adjustment of a variety of the K3's parameters from your PC.

Midway between them and using WSPRLite to compare two antennas, in this case one with a counterpoise and one without, the Reverse Beacon Network or WSPR Reporter would give far more insight than modeling and contacts made. The RBN will give near real time results for locations where there are receivers and where propagation exists. If you used CW to call CQ, you could download that day's data and view the RBN results of your CQ's. There are many more WSPR receiving sites, but that would require using a computer with one's portable transceiver. If additional weight, time, and a small amount of battery capacity aren't big issues, bring along a WSPRLite transmitter. Spend as much time as you are able and willing then analyze the data at the WSPRLite DXplorer web site. Bring a friend with his or her gear and another WSPRLite transmitter and you'll get real data comparing the two configurations from on-the-air tests that are meaningful. You can find a copy of my presentation on the subject at: http://caravan-club.squarespace.com/s/2018-May-Mader-HF_Antennas_and_Propagation.pdf.

Since the KAT500 and KPA500 do not switch to 40M or 160M, I find it odd that both boxes exhibit the same symptoms.?? I'd check to see that RF is actually getting to the KPA500 and KAT500 on those 2 bands.? If no RF or inadequate RF level then they won't switch. You can switch the antennas via the manual switch on the Amp and ATU.?? Does this work?? And if it does switch then will the KAT resolve a match on the band and antenna of choice???? It should. If not then pressing the TUNE button on the KAT should force it to resolve a match as long as 10 watts or so RF is present. 73 Bob, K4TAX On 6/2/2019 12:56 PM, Paul Ecker wrote: > Bob - radio is a Flex 6600, so not using a ACC cable per se.

So am going to do some trouble shooting on the Antenna itself and the feed line. 73 Paul w2eck On Sun, Jun 2, 2019 at 11:16 AM Bob McGraw K4TAX wrote: > From your earlier with the tuner and amp not switching, I would connect > the cable ACC direct to the amp from the radio.

It does not follow the rig freq. But does not follow when Tx'ing on 40 or 160." It seem rather unlikely to me that RF detection would fail in both the KAT500 and KPA500 and that both would fail only on the same two bands. It seems more probable that neither is receiving a satisfactory RF signal on 160 m and 40 m. I think what I would do is try to test the KAT500 and KPA500 separately: Test 1 - Rig > KAT500>50 ohm dummy load. Does the KAT500 track RF freq? Test 2 - Rig>KPA500>50 ohm dummy load. Does the KPA500 band track RF frequency? If neither track 160 and 40 but do track other bands then I would look at the RF signal to check its frequency, amplitude, and spectral purity. A dummy load, RF sampler, and spectrum analyser would make this easy but I don't know what equipment you have available. Is it possible that you have the rig in a cross band split configuration and you are not actually transmitting on 160 and 40? 73, Andy, k3wyc From johnn1jm at gmail.com Sun Jun 2 18:59:23 2019 From: johnn1jm at gmail.com (John Merrill) Date: Sun, 2 Jun 2019 15:59:23 -0700 Subject: [Elecraft] KPA500 Hum/Buzz Message-ID: Probably has been discusses before but my KPA500 seems to have an excessive amount of hum/buzz when transmitting.

This would indicate that the KPA is being PTT. If so, Place a wattmeter in the RF path between the transceiver and the KPA500. That should give a good indication as to the power getting to the amplifier (and thus KAT500). I suspect there is no RF getting to the amplifier on the bands you are having problems with. Either that or no PTT signal on those bands. If this is configurable in the radio, then find the selection and set i two its proper value. Otherwise try to figure out why no rf is going out on those bands. 73!

Ahem, CYBER SECURITY. Now that you've put a popular, modern OS in the K4, and hooked it up to Ethernet (and therefore the Internet), you've just opened a stinking pile of attack vectors. And please don't think that no one will bother figuring out how to 'own' such a powerful connected processor. If you spend anytime reading up on things like Distributed Denial of Service (DDOS) attacks, you will find that things like webcams and routers (which typically don't even have a 32-bit OS in them) have been marshaled to unleash frightening multi-gigabit attacks on various targets. Or, try the newest craze, dropping Bitcoin or other digital currency mining engines on unsuspecting machines, taking them over hog mode, and pegging the CPU at 100%, using your electric bill for their gain. Or, maybe the K4 will be the first ham radio to suffer from a ransom-ware attack, where the poor ham is asked to ante up some ransom (in bitcoin usually, to make it hard to track) to get control of his radio back. True, at least one or more other companies have already stepped out ahead, by putting Windows 10 in their radio. I'm just wondering if anyone at Elecraft has been tasked with dealing with the cyber security aspects of this new toy, and what plans you may have for outside pen testing, etc. have been made. At the very least, you should be using authenticated boot and authenticated flash, protected by a root certificate in an internal hardware trust anchor. 73, -- Dave, N8SBE -------- Original Message -------- Subject: Re: [Elecraft] K4 and Linux Infrastructure From: Wayne Burdick Date: Sun, June 02, 2019 11:52 am To: Leroy Buller Cc: Elecraft Reflector , Lee Buller x86, not PI (ARM).

Each of the memories can be programmed so that both VFO (and mode for each if I recall, been some years) are set, in this case one VFO for USB/FT8 and the other for CW, with their specific frequencies as required. Then you would simply use the A/B for the mode choice of the moment and tap mode if you want DATA A from USB for example. To change channels, recall another memory slot; correct the mode if needed. I went a slightly different route, using ten memories, I have each channel programmed for a specific mode, "1 CW", "1 USB" etc.? then if data, remember that the USB channel is used, but switch to DATA mode. It would be FAR simpler in the US if the BAND was permitted (as other countries allow), not limited to specific frequencies and that would also allow simpler contact with other that have different channel requirements (yeah, it's become a DX band, duh). Rick nhc PS The dual VFO programming in one memory simplifies programming of say, 6M repeaters where the offset is not a constant (i.e. -500 kHz in CA but -1700 kHz in Idaho).

Any ideas on this will be welcome : )" I have no idea if it is possible to implement this with a K3 macro but I agree it's a desirable feature. In fact, I have implemented this and more in my TS-590/Elecraft controller. My "KAT500 Tune" function presents a page with selections Check, AutoTune, and Save. Pressing the button for Check sets the KAT500 key line inhibited and initiates a TS-590 TX-Tune with 5 W. Pressing the button again stops TX-Tune and re-enables the KAT500 key line. I use this to check current SWR as displayed on my LP-100A and to make manual adjustments to the KAT500 tuning solution. Pressing the button for AutoTune inhibits KAT500 key line, initiates TS-590 TX-Tune with 15 W, then initiates a KAT500 auto tune. When auto tune completes the TS-590 is returned to 5 W for TX-Tune, and TX-Tune is stopped. When the TS-590 has returned to RX mode the KAT500 key line is re-enabled. Pressing the button for Save saves the current tuning solution to KAT500 memory. So, not a macro, but something that should be as easy to implement for a K3 as for a TS-590. Less than $30 worth of hardware and a few hours (days, weeks, months......) creating the Arduino code for this and several other functions. 73, Andy, k3wyc From rmcgraw at blomand.net Mon Jun 3 15:51:49 2019 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Mon, 3 Jun 2019 14:51:49 -0500 Subject: [Elecraft] Handedness In-Reply-To: References: <20190603113233.1fa1e31b6b6b329ecc65be958babcc1f.622446fc00.wbe@email09.godaddy.com> Message-ID: I use PF1 to switch between front mike input, no bias, and rear mike input with bias. 73 Bob, K4TAX On 6/3/2019 1:53 PM, Rick WA6NHC wrote: > > On 6/3/2019 11:32 AM, Dave New, N8SBE wrote: >> Yes, but can you have a dynamic mic plugged into one and an electret mic >> plugged in the other? > > > Yes!?

The K4 would not be the target of a DDOS attack, but rather an unwitting participant in launching a DDOS attack as part of robot army of IoT devices. Thousands of hacked IoT devices are for rent on the dark web, for any script kiddie that wants to attack a particular target. Also, it may be popular to use hacked web sites, or various documents with trojan horse loads to deliver ransom ware or bitcoin miners, but there are other known vectors, including various open ports found while scanning. It may be the a router would be able to block access, but the very peer-to-peer nature of the K4 (controlling other K4's or being controlled by another K4 or PC, tablet, etc, means that routers would need to allow certain inbound connections through the router or firewall. These allow for interesting attack vectors, which will certainly be exercised, if possible. 73, -- Dave, N8SBE -------- Original Message -------- Subject: Re: [Elecraft] K4 and Linux Infrastructure From: Paul Gacek Date: Mon, June 03, 2019 4:00 pm To: "Dave New, N8SBE" Cc: Elecraft Reflector , Rick WA6NHC Dave DDOS is quite hard for any end point (PC, iPhone, K4 etc) to deal with effectively.

Ahem, CYBER SECURITY. Now that you've put a popular, modern OS in the K4, and hooked it up to Ethernet (and therefore the Internet), you've just opened a stinking pile of attack vectors. And please don't think that no one will bother figuring out how to 'own' such a powerful connected processor. If you spend anytime reading up on things like Distributed Denial of Service (DDOS) attacks, you will find that things like webcams and routers (which typically don't even have a 32-bit OS in them) have been marshaled to unleash frightening multi-gigabit attacks on various targets. Or, try the newest craze, dropping Bitcoin or other digital currency mining engines on unsuspecting machines, taking them over hog mode, and pegging the CPU at 100%, using your electric bill for their gain. Or, maybe the K4 will be the first ham radio to suffer from a ransom-ware attack, where the poor ham is asked to ante up some ransom (in bitcoin usually, to make it hard to track) to get control of his radio back. True, at least one or more other companies have already stepped out ahead, by putting Windows 10 in their radio. I'm just wondering if anyone at Elecraft has been tasked with dealing with the cyber security aspects of this new toy, and what plans you may have for outside pen testing, etc. have been made. At the very least, you should be using authenticated boot and authenticated flash, protected by a root certificate in an internal hardware trust anchor. 73, -- Dave, N8SBE -------- Original Message -------- Subject: Re: [Elecraft] K4 and Linux Infrastructure From: Wayne Burdick Date: Sun, June 02, 2019 11:52 am To: Leroy Buller Cc: Elecraft Reflector , Lee Buller x86, not PI (ARM).

What would elecraft do about users that break the system but misconfiguring stuff, etc... if they allow users to opt in I would fully expect users to have to agree to owning responsibility for any modifications. This would mean that if you have a problem with the radio and send it in and the problem is solved by reflashing the base image then you should be charged for wasting their time. I would also expect to have the base image given to users so we can fix our own mistakes. I think this problem will exist one way or another. Quite likely elecraft will be legally required to make available some or all of the base image of the radio due to software licences. It is also likely that someone will figure out how to get access to the underlying system. In my opinion elecraft can get out in front by setting expectations and telling users if you do this your on your own from a warranty perspective. It would be nice of them to limit that but they could have that void the whole warranty. It will be interesting to see how they handle this. This is precisely the reason I got put my deposit for the second group. I want to see how this shakes out before commiting which means I cant be the first one with the radio.

That works too, and it's not like I'm going to run out of memory slots, and if all 10 were placed into a channel hopping block, you can move from one to the next with the BK only. > > It would be FAR simpler in the US if the BAND was permitted (as other > countries allow), not limited to specific frequencies and that would > also allow simpler contact with other that have different channel > requirements (yeah, it's become a DX band, duh).

When I asked if the K4 would be able to 'talk to the outside world', I meant an ability to initiate communications with a web site, a server, or something else. Yes, allowing users to get down to the operating system would probably be unmanageable. But what about loading 'apps', in the same way that you install apps on your phone? I could see a logging app, a reverse beacon app, or something else that would add real functionality to the radio.

At some level even if they do "only" have apps they will have this problem. App developers will need to be able to modify and test things. Also I doubt that there would be many apps if this is a separate process than mainstream linux/windows. why would a hobby developer want to build a separate thing just for one pretty expensive radio when they could just build the app for linux or windows and support everyone.

I think and surmise that the engineers at Elecraft had to put in a pretty powerful OS and processor to do all of what they want to do in the box. Especially with 4 RX in the box plus all the other things it will do. But, besides the issues mentioned in this thread it is exciting what the possibilities are with the CPU in the box. I think it is ingenuous. Lee K0WA On Mon, Jun 3, 2019, 5:45 PM Lynn W.

I originally loaded the 60m CW frequencies in VFO A for my 60m channels since I'm more likely to use them working SOTA activators. However, I usually scan the SSB channels. Thus, I swapped between VFO A and B so I can scan USB channels and select the appropriate VFO B CW channels when needed. This comes in handy when someone suggests 60m for USB or when I see a SOTA dude spotted on 60m CW. 73, Bill, K8TE, waiting "patiently" to return home and start using HF again!

It's just beyond what any manufacturer can do.? I suppose Eric, who is noted for his business skills, could start up an "E-tunes" app store for the K4, with developer standards, testing, and the like.? I doubt that's remotely close to the top of his To-Do list however. Having just had my 79th birthday yesterday [thanks for all the HB's!], I remember when Heath came out with an analog computer at what would have been the beginning of the "Science Hobbyist" revolution.? Without the Internet, there were no Email lists of course, but the number of "I did this and it didn't do what I expected" inquiries was way more than they expected.? Fortunately [for Heath] the customer base was very rapidly exhausted and the Heathkit Analog Computer silently sailed into the sunset. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County PS:?

Imagine spending an hour working through a problem just to find out that someone is running modified firmware (and this is firmware, not software for us to play with). It's an embedded system. If you break it, you own both parts, and Elecraft would need a 100% reliable way to verify that you didn't introduce bugs.

(Yup - we have been a little busy as of late with the K4 introduction ;-) To be clear - we do not plan on granting open access to the main CPU or K4 internal operating system. That would be a impossible situation to support and it would significantly impact product stability. At this point, any additional internal software applications developed for the K4 will be coming via Elecraft. Of course we will certainly will have a robust external API for the K4.

Never an issue. More than a few contesters drag radio gear several times a year to island stations in the Caribbean. One of my neighbors, W0YK has long carried on a pair of K3s in Rose's cases to P49, where he regularly wins RTTY contests. He had Rose put velcro on one surface of each so that they "clamped" together to be one piece of luggage, then pulled them apart to stow them in the overhead. 73, Jim K9YC From xdavid at cis-broadband.com Mon Jun 3 23:30:23 2019 From: xdavid at cis-broadband.com (David Gilbert) Date: Mon, 3 Jun 2019 20:30:23 -0700 Subject: [Elecraft] K4 Production Prognosis In-Reply-To: References: Message-ID: You're asking for concrete answers to questions Elecraft has already stated for the most part are not yet final.?

This is computer hardware and software. A business where ?before end of year? really means 2 hours before midnight. And the ?First Quarter? runs until May or June. Don?t look for all the features to be fully implemented on first delivered radios. Even the K3S is still a work in progress! About ?Production Runs? Elecraft is a small company. They will prob build 25 or so radios for field testers. This will allow some training for the small staff of assemblers. Once they are satisfied with the product, they will begin assembling the first radios. These builders are not robots. But humans who must go thru the process of building a kit, without the ?assembly manual? and it takes time. Once built, it goes to the burnin rack where it will sit for up to 24 hours being tested and evaluated. Now to packing and shipping. This ?run?, one radio. The first week may see a dozen radios out the door. It slowly grows from here. I?ve waited in line for a KX3, a PX3, and K3S. I visited the ?plant? a few years ago and spoke with a K3 builder. He said he could build a K3 in under an hour. But he?d built maybe a thousand by then. And the parts were all there in bins around his work area.

The problem these days, is not only if something is exposed to the www, but even if it can only be "seen" by other nodes on the same LAN.?? Such as the main shack PC, that probably can reach out to the WWW.? Once "something" gets into that PC (or your IoT lightbulbs!)? It can at it's leisure scan your shack (and/or home) LAN, looking for other nodes/devices to poke at later, after "phoning home" with the details of what it found. You all have got your dumb IoT devices (including TV's and PVR's) on a segregated VLAN haven't you?? No!? You have work to do then! Also, irrespective of the OS used, one way to reduce the chance of user induced mayhem, is to boot from a (protected) read only medium, copy the OS to RAM (for speed) and use another SD card as persistent storage, with an option during the initial boot (if for example) some combination of keys are held down, to load the default settings into the "user" area, as an easy "Factory Reset" feature. Then, whatever the user does, when (not if) they muck it up, there is an easy get out of jail free card. As to the network security issue, the only "secure" network device, is disconnected, powered off and in a sealed & screened box!? Period.? What may be regarded as secure "now", in six weeks time could be hacked to hell and back by script kiddies all over the world.? In truth, currently, the bad types have the upper hand. Sadly (as with any OS) a continual surveillance of the ecostructure is needed, and the inevitable updates.? There are many ways to do that of course, some easier, and some more "secure" than others.? Security and convenience are mutually exclusive, sadly.? (In the case of a RO boot medium, a switch would need to be flipped to allow a (once verified) image to be flashed onto it, one time, said switch auto resetting once programmed.)? Or another card shipped in by post, and that's not as secure as you might think either! Regarding legitimate use of a LAN/WAN connection.? One would hope(?) that at the bare minimum:- The radio control firmware is not run as root. Incoming ssh requests are ignored/blocked. In the case ssh connections are allowed, root login by ssh is blocked, and only pre authorised (by certificate) user(s) are allowed in (Elecraft themselves for example.) The use of su and sudo are blocked if anyone does get to a command line as "a user".? Also browsing the OS software/settings folders is blocked, should the firmware die, leaving the user at a command line. Have the radio "reach out" to Elecraft central when needed using OpenVPN (for example, using the current state of the art security model) to check for updates (user initiated) or for Elecraft to remote admin, after telling the user how to initiate that feature.. Any such automatic updates are "staged" within the rig, until they can be verified as complete, uncorrupted and genuine, before being applied. Any custom daemon software intended for legitimate remote control/interface use, should be written in such a way, that any corrupt or unknown commands (and/or parameters) are ignored, not even returning any error code to the initiator.? Greatly reducing the ability of it to be "fuzzed" for vulnerabilities. Also, .? Similarly, any code created to allow the radio to control accessories via the LAN port (PA's ATU's etc) should be created with security in mind.? Such command & communication links should be encrypted, so only the intended endpoints can see/use the data.? ESPECIALLY, in the case that such links traverse the public internet...? (A licence requirement here in the UK by the way!) Any built in Digimode software (PSK, RTTY, CW, JT modes etc) should also be run in a VM, within the radio.? Hopefully preventing any possible remote takeover issues via that route!? (None that I know of at this time, but ...) ~ ~ ~ Trouble with all the above it, it takes */a lot of time and effort/* by the equipment makers to do, and do right, plus the testing of it all, or contracting in some qualified penetration-testing types to test it all for you.? And that cost money.?? That, and capable hardware to do all that, is also not exactly low cost (but is getting lower in cost.) Also, all the above is not unique to Linux, */all OS's/* have their issues, just that some are better(or worse) than others. Effective Security is difficult to make user proof.? Educate the users first.? If nothing else, listen to the "Security Now" podcasts by your countrymen.? https://twit.tv/sn? (Another episode later today.)? Entertaining, and you might get an appreciation of just how much mayhem is going on out there right now. Happy Days! Dave B G0WBX. (I have learnt much of the above the hard way, by digging friends and family, and some work colleagues, out of the mire induced by a lack of knowledge of how to stay safe on-line, and from the Security Now podcasts.) -- Created on and sent from a Unix like PC running and using free and open source software: From rich at wc3t.us Tue Jun 4 06:57:22 2019 From: rich at wc3t.us (rich hurd WC3T) Date: Tue, 4 Jun 2019 06:57:22 -0400 Subject: [Elecraft] K4 Production Prognosis In-Reply-To: References: Message-ID: I?m amazed at the amount of detail some list members expect from Elecraft for their new products.

You can?t even hear signals on other frequencies until you tune the mag loop. If you can run a 26 foot wire, do that. Use a 16 or so foot wire on the ground as a counterpoise. Connect them to the KX3 with a double binding post adaptor and press ATU TUNE. Or you can use a railing-mounted whip, like this one. MFJ also makes a 12 foot whip which might fit this coil. With a short feedline, I?d probably bypass the coil and let the KX3 ATU do the work. https://www.mfjenterprises.com/Product.php?productid=MFJ-1622 wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jun 4, 2019, at 11:17 AM, Kevin, N4TT wrote: > > I have had great luck with the simplest of end-fed antennas and the KX3. > Particularly out at the picnic table I can just find a convenient tree to > toss up one end with the other end at the table.

SSB QRP with a compromise antenna are both negative parts of the equation -- SSB is about ten dB behind CW because of noise added by the additional bandwidth it requires. > I understand that it is very narrow bandwidth (high q?), but it occurs to > me that if they are being used for ssb at all, that there should be enough > bandwidth to handle current digital modes. Bandwidth is quite enough for SSB. > Has anyone tried using a magloop as a gain antenna for ft8? It's not a "gain" antenna. It's a compromise antenna, with the ability to null out a single noise source on receive. FT8 is 6-10 dB better than CW with very good operators on both ends, so FT8 is a very good mode for QRP and compromise antennas. > I may take mine > for a drive with my KX3 to find a hilltop... That's a great idea -- the hilltop can also be good for 6-10 dB. 6dB is 4X the power, one S-unit, 10 dB is 10X the power, two S-units. 73, Jim K9YC From k6dgw at foothill.net Tue Jun 4 15:02:40 2019 From: k6dgw at foothill.net (Fred Jensen) Date: Tue, 4 Jun 2019 12:02:40 -0700 Subject: [Elecraft] 60 meters In-Reply-To: <1559603627195-0.post@n2.nabble.com> References: <047ec8b0-27f2-56b8-790c-617d18ad17ae@gmail.com> <169f25a0-8de9-0282-5a55-5b347643d9f4@foothill.net> <1559603627195-0.post@n2.nabble.com> Message-ID: <2f1bec57-3540-9c04-af92-bb2a6dbe5276@foothill.net> This began as a simple question, I can't understand why it is so hard to explain:? K3 frequency memories hold frequency, mode, and DSP BW for both VFO A and VFO B.? I used the K3 Frequency Editor to load the CW parameters into VFO A and USB parameters into VFO B in 5 consecutive memory channels.? Those 5 are "ganged together" with an "*" in the name, IIRC. When I rotate the Big Knob, I expected the VFO's to rotate through the channels [end-around].? VFO A does, but VFO B does not follow, it remains on whatever channel I originally selected. The sequence M>V, Select memory, M>V sets both VFO's to the parameters stored in that memory, as one would expect.? Selecting a new memory with the BK should load the parameters for that memory into both VFO's, or so it would seem.? It does for VFO A. It doesn't for VFO B.? My question was, "Is this a bug or intentional behavior?"? If it's intentional, I'd be curious what the use case is for that behavior.? I'm also aware this is a K3 question and likely to get lost in all the K4 commotion. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 6/3/2019 4:13 PM, K8TE wrote: > While you can scan or dial through VFO A, once you "land" on a particular > channel, the VFO B frequency and mode associated with that channel is > available by using the VFO A/B button. > > I originally loaded the 60m CW frequencies in VFO A for my 60m channels > since I'm more likely to use them working SOTA activators.

Applications that expect CTS/RTS handshaking will need that connection - most applications will work without it. 73, Don W3FPR On 6/4/2019 3:26 PM, Harry Yingst via Elecraft wrote: > To Clarify this information > - > The color codes are from the wires on the FTDI USB Cable (USB-RS232-WE-1800-BT-0.0) > - > The only wires that will be connected are the > Yellow Wire that will be connected to Pin 2 of the Male 9 pin connector > Orange Wite that will be connected to Pin 3 of the Male 9 pin?connector > Black Wire that will be connected to Pin 5 of the Male 9 pin connector > - > The Green Wire on the USB cable is the RTS Line > The Brown Wire on the USB cable is the CTS line > The Green and Brown Wires should be connected to each other and nothing else.- > The Red wire is unused > - > This should clear up any confusion > > > I'm passing this info along for those who may have a K2 and find this useful. > > FTDI makes a USB to RS-232 Cable Part Number: USB-RS232-WE-1800-BT-0.0 > The cable has a?USB plug on one end and is terminated in wires on the other end. > -- > Here is the Pin-out to make a USB to K2 Cable > > Color - Signal - Notes > Yellow - RXD - Pin 2 on 9 Pin Connector - RS-232 Data In From K2 > Orange - TXD - Pin 3 on 9 Pin Connector - RS-232 Data Out To K2 > Black - Gnd - Pin 5 on 9 Pin Connector - Ground > Green - RTS - Tied to CTS Line > Brown - CTS - Tied to RTC Line > Red - Power - Unused - 0.0v > -- > ______________________________________________________________ > 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 hlyingst at yahoo.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 donwilh at embarqmail.com > From elecraftcovers at gmail.com Tue Jun 4 16:19:59 2019 From: elecraftcovers at gmail.com (Rose) Date: Tue, 4 Jun 2019 14:19:59 -0600 Subject: [Elecraft] Case and dust cover clarification Message-ID: I've already had two inquiries ...

Wouldn't a bank's commercial lending officer ask such questions if a business were seeking a commercial loan from them? As a 50 year career banker, I can assure you that he/she indeed would. In this situation you are the lender and giving an interest free loan with no promise of anything other than a queue position. I owned an K3 from its 2007/2008 beginnings until four years ago. When I sold my K3 (for numerous reasons), I also left this list in part because of the frequent snippy and defense comments that seemed to emerge anytime anything difficult, critical or probing was posted here. I see not much has changed. Enjoy your K4's. Save your flames. I'm moving on ... again.

Loops will work in places where wire antennas are banned or won?t work at all due to local noise (like an apartment balcony). Members of our club set up antennas at a special event under a concrete overhang at Toronto?s Central Reference Library. All the wire antennas heard was noise while the Alexloop got out just fine. Having said that the need to retune every few kHz is an issue and CW and digital modes are more effective than SSB. I?ve run loops, end-feds, dipoles, verticals and beams and the basics apply. In general wire antennas properly installed work better. Dipoles work better (quieter and less possible interference) than end-feds but end-feds are way easier to get up. If I couldn?t get a wire antenna up (I once put a 15-meter dipole up using popsicle sticks on the peak of roof of a two-storey linked house that was invisible from the ground but set off the smoke detectors if I ran more than 20 watts) I'd consider a mobile antenna like a Tarheel with radials and if that wasn?t possible I?d run a loop. Let?s put it this way, I?m not selling my Alexloop. 73 - Peter - VE3HG From nv4c.ian at gmail.com Tue Jun 4 18:50:10 2019 From: nv4c.ian at gmail.com (Ian Kahn, NV4C) Date: Tue, 4 Jun 2019 18:50:10 -0400 Subject: [Elecraft] Alpha Antenna/KX3.

On Channel Hopping, VFO A follows the hop to the next channel, but VFO B does not. While a "fix" may be coming sometime, it is not likely to be coming soon. So I propose a workaround. The simple solution is to set 10 channel hopping memories instead of only 5. 5 for SSB/DATA and 5 more for CW. I doubt that you are using all 100 memory slots in the K3. Arrange them any way you want - each CW memory next to the SSB memory, or go through all 5 SSB memories and then the next 5 are CW. Put some identifier in the label so you can see which is which without referring to the frequency. 73, Don W3FPR On 6/4/2019 3:02 PM, Fred Jensen wrote: > This began as a simple question, I can't understand why it is so hard to > explain:?

The frequency shift is constant for all channels, so one Macro will do for all channels. Assign the Macro to a PF button. 73, Don W3FPR On 6/4/2019 7:52 PM, Fred Jensen wrote: > That doesn't work Wes, the problem is simpler than that.?

I use a Wolf River Coils mini with the large whip (210in I think) for portable ops. It came with three radials. After reading Rudy Severns? articles, I built a set of 16+- ft radials (total of 18 - 3ea of 6 into 1) for the unit. I have only anecdotal evidence, but I think the more robust radial field improves the antenna system. They take only a few minutes to deploy and coil easily for storage in the travel bag I use. It?s a good recommendation, Rich!

It would also allow ADCs and associated processing to run slower or lower down in relation to its Nyquist frequency so allowing for more detail in the sampled signal. Also can narrow band analogue filtering beat the dynamic range of the ADC? If its top 10 bits are taken up handling that huge strong signal in its input passband then you've got fewer bits left for your signal of interest. So both high bit depth and high sample rate in comparison to signal are harder to achieve. The opposing view being the cost of achieving a high quality Superhet conversion? If direct sampling and high speed signal processing (FPGA?) can achieve the results so much more cheaply and simply and reliably? Like the Class D amplifier in reverse. - Richard (M0RJC) On Wed, 5 Jun 2019 at 03:19, Wayne Burdick wrote: > The superhet module buys a lot of BDR improvement.

NodeRed allows me to control the Amp via just about any client and as well to share the status of the amp with MQTT. I have carefully reviewed the Programmers document and I have some questions I hope that someone may be able to answer for me. The P for the boot loader doesn't always want to work as documented. There are times when I am not able to communicate with the Amp at all requiring a power cycle to get it back online. I also know I did not send it a D, so it is not in a download state. The document states that receiving any other data while in boot loader mode will be ignored, but I am not convinced that to be true since the Amp will start communicating. I think that something else is getting to the boot loader and that is causing it to ignore any additional communication. I do know the the Elecraft App works correctly as you work through the Start Hosting part. Do I need to do an I, then a P and then a ; to see if we are online? The other question is if I send the Amp a ^ON0;, are we in boot loader mode or still in operational firmware?

MFJ makes a 17 foot collapsible whip antenna which sells for around $60 IIRC. With this whip I can extend to a resonant quarter wave anywhere from 6m to 20m. Although I experimented with properly cut radials for each band I found it was not worth the trouble. Four 17 ft long radials work well enough for me and are easy to coil up and transport. The whip itself collapses down to about 31 inches long. Another ham did a nice writeup here: http://www.kd5fx.com/FXportable/fx_portable_antenna.htm With this setup I was able to work VP8SGI on 20m CW with my KX3 while travelling in Arizona.

My 2 cents on the Mag loops is that they can be a useful addition in the right circumstance if you spend the time to learn how to use them properly. I do a lot of SOTA and portable work and I find the loop is often a good solution for a quick setup especially if you need a low profile or don?t have good support options for wires. I prefer a resonant dipole if possible,or an end fed with counterpoise,but the loop can be effective where that?s the best option. The trick is to get it at least 6-8 feet high and far enough away from any metal structure,and a reasonable distance from you the operator! They can be finicky to tune and you can?t move easily more than 10 kHz without retuning. Since I?m usually just on SOTA frequencies or QRP it?s not an issue. CW is really the best mode as you?re limited in power to usually 10-20 W by the loop. You must pay close attention to construction also-I personally found the W4OP loop to be of superior quality compared to others. Dale W4OP is an active ham who takes pride in his product (not unlike Wayne and Eric!). They are kinda spendy but you get a very well made unit plus excellent customer support. They?re a bit bulkier than others but will cover more bands effectively,including 40 and 60 (and 6) meters than other brands . I use a collapsible photo light tripod to mount mine-if you use a tripod you should order the tripod adapter as well. They now offer a remote tuning option which the late Joe Everhart N2CX reviewed recently in QST. Dale W4OP also is active on the Mag loop reflector and will offer excellent advice on home brewing loops should you want to try that. Before you buy one try to borrow one and do some research to see if it?s the right fit for you. Lots of options for antennas.

My 2 cents on the Mag loops is that they can be a useful addition in the right circumstance if you spend the time to learn how to use them properly. I do a lot of SOTA and portable work and I find the loop is often a good solution for a quick setup especially if you need a low profile or don?t have good support options for wires. I prefer a resonant dipole if possible,or an end fed with counterpoise,but the loop can be effective where that?s the best option. The trick is to get it at least 6-8 feet high and far enough away from any metal structure,and a reasonable distance from you the operator! They can be finicky to tune and you can?t move easily more than 10 kHz without retuning. Since I?m usually just on SOTA frequencies or QRP it?s not an issue. CW is really the best mode as you?re limited in power to usually 10-20 W by the loop. You must pay close attention to construction also-I personally found the W4OP loop to be of superior quality compared to others. Dale W4OP is an active ham who takes pride in his product (not unlike Wayne and Eric!). They are kinda spendy but you get a very well made unit plus excellent customer support. They?re a bit bulkier than others but will cover more bands effectively,including 40 and 60 (and 6) meters than other brands . I use a collapsible photo light tripod to mount mine-if you use a tripod you should order the tripod adapter as well. They now offer a remote tuning option which the late Joe Everhart N2CX reviewed recently in QST. Dale W4OP also is active on the Mag loop reflector and will offer excellent advice on home brewing loops should you want to try that. Before you buy one try to borrow one and do some research to see if it?s the right fit for you.

The FTDI adapters work best, if you are using a Prolific adapter, I recommend replacing it. Set the K3 baud rate to 38400 in the RS232 menu. Do you also have a P3? If so, set its baud rate to 38400 as well. Be certain you are using the correct COM port in K3 Utility. The COM port is assigned to the USB to serial adapter, and NOT to the K3. Use Device Manager in your computer to determine the assigned COM port. Open PORTS and unplug the adapter from the computer. One of the COM ports should go away - then plug it back in and see which COM port is assigned. Put that COM port into K3 Utility and TEST COMMUNICATIONS. Windows sometimes changes the COM port assigned to USB to serial adapters - thanks Microsoft! 73, Don W3FPR On 6/5/2019 5:37 PM, Mike March wrote: > My laptop is not seeing the K3 using the K3 Utility.

That is akin to someone who buys a new K2 and searches for mods and changes that may date back to 1999. Those mods are no longer applicable because the K2 has been updated to incorporate all those prior changes. I have answered several questions about those old changes to the K2, and in all cases, the answer is the same - it is incorporated in your new K2. So when the K4 is released, it will contain all the changes agreed to during Field (Beta) testing, and the comments during Field Test will no longer be relevant. It is that same way for the Beta Test period of any product. 73, Don W3FPR > > On Thu, 6 Jun 2019 at 04:54, Leroy Buller wrote: > >> Are there any K4 Beta Testers out there yet?

We were taught that you can recover signals up to the Nyquist frequency (half sampling frequency) before aliasing becomes an issue. People low pass filter well before then to avoid aliasing issues, but it means you need a sampling frequency sufficiently more than twice the highest frequency you want to record. So presumably for the 6m band that's sufficiently greater than 110,000,000 samples per second. What gets me though, is when you look at the waveforms and the sampling waveforms, a signal at the Nyquist frequency could have magnitude from 0 to full size depending on its phase with respect to the sampling. Assuming regular sampling (do any dither the sampling?). Move just below Nyquist and you'll see a beat frequency come in as it moves in and out of phase. I guess the maths is based on infinite time - Fourier being the integral from -infinity to +infinity - but we've not got infinite time to listen to an infinitely long SSB signal. You can buy a reasonably cheap digital oscilloscope (Tektronix TBS1000 - ?600) which boasts 1GS/s so a Nyquist frequency of 500MHz. They claim 50MHz analogue bandwidth. (If you're thinking of buying this double check the figures first rather than take my work for it. The marketing material was a little opaque). A 2nd order filter (cheap, simple) with a 3dB point at 50MHz and 40dB/decade would be about 40dB down by the Nyquist frequency. In the lower bands, say 10MHz, the first aliases are from 990MHz which is 55dB down if I remember my maths right. I'd assume someone would use better than a 2nd order filter or a faster sampling ADC.

It will allow you to do all kinds of things, pretty much anything you can think up, and has the added advantage of eliminating a bunch of control cables. You can use inexpensive multiple relay cards that are readily available online to activate any kind of switch you want. I replaced a pair of Station Masters with the GHE system a couple of years ago and have been very happy with the results. 73...

I used a junkbox air-gap capacitor and a 10x vernier knob to tune it. I ran 100w through it on FT8 and ran an infrared thermometer all around it and it barely warmed past room temperature. From inside my house in the Philly burbs, I got FT8 contacts in northern Wisconsin and Fargo, North Dakota on 30 meters, so I think it was getting out pretty well. I was running 30 watts or so on it at the time, as I recall. Not bad from indoors on the first floor with a steel workbench a foot away and resting on a wire rack. Someday I'll take it on a park run and see how well it works out in the open. I'm considering making a better loop first though, as this one is pretty flimsy and probably won't stand up to any significant wind. I need to redesign it for more rigidity and probably a somewhat larger loop to get at least SOME efficiency on 40 meters and perhaps even a little on 75/80, though that's asking a lot of a small loop. 73, Gwen, NG3P On Thu, Jun 6, 2019 at 12:11 PM Edward R Cole wrote: > Interesting reviews on some of the loop antennas.

I have not seen any detailed specifications out yet but it confuses me when I read that the K4HD will have a K3S front end. I've got 3 K3's that are fully upgraded so maybe the K4 line is just a nice product packaging idea and not a serious jump in performance?

SMD soldering is actually much faster than through holes because you don't have to trim leads. It is just a matter of getting used to small parts. Magnifying glasses will definitely be necessary for most of us. Reviving K1 with SMD parts will make a very trail-friendly radio.

In the winter months I do a lot of SMD work. I don't have a quality soldering station at all. I use solder paste from a small syringe, cheap tweezers, a $2 coffee cup warmer (WalMart), a small $25 heat gun used by scrapbook crafters (Michael's), and a regular desk magnifier lamp. For a few parts, I use tweezers and my regular Hakko soldering iron with a pencil point.

A K1-level SMD kit would be no problem for anyone capable of attacking a thru-hole K1 or K2, but Wayne clearly addressed that possibility, and rightly so. The K1 may be dead, but not soon forgotten.

I use an i-Extruder pencil (a stepper-motor powered syringe dispenser) to apply dots of solder paste to the pads, then tweezers to pick-and-place the components. If it's a small area, I use my hot air station to melt the paste and solder the parts. If it's a larger board, I use a microcontroller-driven heating plate called a ReflowR to precisely ramp up the heat, melt the paste, and cool it off so as to cause the least thermal shock to the board or the components. I'm not nearly as good at the latter as I am with simple thru-hole components, or a few larger SMD components. 0603 and above, I do by hand if there's just a few. Most people suggest a "tack one end then get the other" approach, and while it works, I don't find it as efficient as I'd like. So I use the same i-Extruder to apply dots of Amtech "tacky flux". I place the components on the pads, held down by the tacky flux, then tack-solder one end, then the other. If it needs it, I go back and flow enough solder to make a good fillet, but frequently the tack makes a decent fillet with that good flux. That's how I built a Zachtek WSPR beacon a few weeks back. It had four low-pass filter stages, each with several surface mount components. It was few enough that I didn't think it warranted the reflow plate, though I did use the hot air pencil to clean up the fillets I did with my soldering iron. Came out looking really good, and working well. 73, Gwen, NG3P On Thu, Jun 6, 2019 at 2:33 PM rich hurd WC3T wrote: > Dead bug construction ROCKS. > > On Thu, Jun 6, 2019 at 2:02 PM Wayne Burdick wrote: > > > I miss the good ol' days, e.g. high school, when my quick 'n' dirty > > transceiver projects were built by twisting component leads together.

SMD components on a board in, say, a K3 were ramped up to about 225 deg C (435 deg F) over SEVERAL minutes. They're designed to withstand those temps. I don't know what the little heat gun I use puts out, but it doesn't burn paper which famously burns at Fahrenheit 451. #2 It happens. When the solder goes molten, the surface tension moves parts around a little. Usually, it tends to position the part on the pads better than you can with tweezers on clean pads. Sometimes parts stand on end. Not a problem reheat it and push it down. Things don't always go perfectly on thru-hole either. Don Wilhelm helps people nearly every day with problems that turn out to be soldering related on K2's. They happen to everyone. Not a big problem. BTW, notice that the solder paste on the IC is not carefully applied to each pad. Instead, the solder is applied ACROSS the pins in two lines. When it goes molten, the surface tension positions the parts and draws up any solder bridges onto the pads. Doesn't always work, but I've done some large ICs that way without solder bridges. When it happens, dab the connection with an iron and the bridge disappears. Safe and easy. I understand not everyone has the eyesight or dexterity for it, and not for all sizes of SMDs. I avoid the very small stuff as do most hams who use SMD. Amateur radio is about new technical challenges whether building or operating. This is a very accessible and useful skill that can be acquired with inexpensive tools and a little practice.

I understand that the K4HD will have a selectable feature that would allow it to use either the direct sampling or the superhet front end.

I know I could operate remotely from a PC, etc. but would prefer the "real radio" feel with knobs, a plug in paddle, etc. and having the panadapter screen in the mini would be a plus? I use a K3 mini now but not with a P3. 3. My primary station is built as a remote station in FL in partnership with Paul-W9AC. We use Verizon 4G LTE for internet and are limited to 30 GB of data per month (without upcharge). How data intensive is the K4 with the panadapter in remote operation versus the K3S -- assuming it would be controlled with a K4 mini or another K4 to get the panadapter feature??

Maybe. Someday. But I can't say for certain. Another possibility is a "K4/0", i.e. a K4 with only a front panel and host interface module, but in the same size chassis as a K4.

I used to run a home business building smd kits for others after a career as a component level technician where I did smd repairs. But the last generation of MOT intrinsically safe radios required a $10,000 school and a dedicated repair station to be qualified by MOT to do repair work. MOT instituted a flat-rate repair service for about $150 per radio which turned me into a troubleshooter and shipping dept. I retired a few years after that. I bought a Haako FX-951 repair station for that business and used a lighted magnifier. SMD assembly is much faster/cheaper and can be automated on a production line with better reliability than human-built. That's why todays tech does system troubleshooting to the board level and then board replacement. New boards are cheaper than paying the tech to repair them. Most commercial radio shops charge $100-$125/hour for servicing. Another ten years and there will no longer be component level techs. Very hard for a small business to compete using a human production line of solderers. Probably only find a small line to build pre-production units for testing/re-engineering. --------------------------------- There probably aren?t more than a handful of folks who could actually build an SMD kit of any size without having to send it back to Elecraft to be built or to fix the mess.

My sense is that while Elecraft is exceptionally busy with the K4, if any real serious commercial life was left in the K1 then Elecraft understandably would want to exploit it. The but comes from Wayne granting the right for the NorCal 40 to be ?copied? but only as a non profit do it yourself project that has a PCB at cost (I think).

There are alternative measurements, done by ARRL as part of their lab tests, that quantify an even more important performance spec -- CW keying bandwidth. Several years ago, after discussions about excessive CW bandwidth at a WRTC, N0AX arranged for me to get ARRL's data in electronic form. I exported that data to a spreadsheet and plotted data for most of the rigs on the same graph. That report is at http://k9yc.com/TXNoise.pdf I've also done some of my own measurements, using my second K3/P3. The first set of data is at http://k9yc.com/P3_Spectrum_Measurements.pdf A second set of data focuses on the FTDX5000. I measured my neighbor's rig before and after he had loaded Yaesu's "fix" for it's very excessive bandwidth.

It bugs me that so many latch on to "top of the list" and I have, perhaps tongue in check (perhaps not), suggested to Rob that he sort on some completely irrelevant parameter to see people's reactions. I wonder how many would dump what they had and buy new "top of list". In my opinion being very familiar with what you own, and knowing how to get the best out of it, is far more important than having the "best" rig. I've been a TS-590S owner for nearly 8 years and still not seen anything that would tempt me to get rid of either of them. 73, Andy, k3wyc From ehr at qrv.com Sat Jun 8 19:38:35 2019 From: ehr at qrv.com (E.H.

I have one windows box for Amateur radio, and the other computer I use for day to day things is a Linux box. I am considering making a clean W7 install there on a VM, and just keeping an image of it once W7 goes no update. That way, if/when my W7 install gets compromised, I can just replace the soiled image with the good image. I am still thinking about if I just want to go W10, and be done with supporting a dead OS, that will probably have a ton of exploits within a year of MS ceasing support. I will probably go with 10, as that seems a simpler path, and one the vendors will support. Remember, after W7 goes no support from MS, most of the authors will forget W7 exists, while most of the hackers will fall in lust with it. 73s and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Technical Specialist ARRL Volunteer Examiner ARRL Asst.

I've owned an Astron RS-35M, which was great until it started buzzing like crazy. I swapped that out for a Samlex SEC-1235M, and did the fan mod to keep the fan on constantly at low speed. The problem here is that when I'm running FT8 or RTTY for more than about a half hour, the fan goes into high speed and stays there for an hour or more, long after the rig and amp's fans have shut off. And because it's a tiny fan moving a lot of air, it's incredibly loud. I'm looking for an RF-clean power supply (either linear or switching) that can deliver 25A continuously without requiring a cooling fan of any kind. All it's running is the K3s/P3 and a couple of boxes with less than 1A draw each. The front panel meter on the Samlex is showing a tad over 20A when transmitting 100W in FT8/RTTY. Any suggestions?

I have the samlex, astron ss30 and a rm30. The Quiet one is the rm 30. You might try to tighten the bolts on the transformer. That helped mine, but no fan. One issue is keeping the power cord short to keep from getting a voltage drop. You also have to use the right gauge of wire and 45 amp power pole connectors. So, the power supply has to sit close to the rig. I have a cord of 24 inches. I have very little voltage drop and the K3 runs better at 13.7 than 11.8v. So, I have learned to ignore the fans on ft8, and I wear headphones for the other modes. Your mileage may vary, but if it has a fan you will get noise. The AL 82 also is noisy but that's life.

When I first got into So2r years ago, I discovered an entire layer of very weak signals when I switched to usingTenTec Omni V and Omni VI; this was related directly to lower phase noise in so2r where the other radio was not a TenTec. Also, high level blocking allows you to hear those weak ones in S & P that you would otherwise roll right over especially when the band is full of strong signals. If you are not into cw contesting, and in so2r in particular, then what I just said doesn't matter and lots of radios become good radios. I have used nothing in so2r better than 2 x k3, with Omni VI, Orion and Tentec Eagle almost as good. After those, there is Kenwood ts590s. The thing is, you cannot notice the signals that you are not hearing if you have two radios that perform equally poor, and especially with respect to phase noise. 73, will, wj9b CWops #1085 CWA Advisor levels II and III http://cwops.org/ -------------------------------------------- On Tue, 6/4/19, Wayne Burdick wrote: Subject: [Elecraft] K4: superhet vs. direct sampling To: "Elecraft Reflector" Date: Tuesday, June 4, 2019, 8:18 PM The superhet module buys a lot of BDR improvement.

A: As Rob Sherwood noted many times before finally immortalizing this point in his must-read footnotes, A-to-D converters sharing the same part number are not all created equal. The long-time previous occupant of his Top Spot benefitted from a never-corroborated monotonicity in its ADC's LSBs. An act of god. The product of a very good day at the silicon foundry when, serendipitously, all the bunny suits were defect-free, and no one was exhaling molecules of grain alcohol or other substances from the night before. That said, most ops can get by without the extra BDR and IMDDR3, because they're not situated in the RF equivalent of the Gulf Stream. Hence the different K4 models. 73, Wayne N6KR > On Jun 4, 2019, at 5:10 PM, Lyle Johnson wrote: > > Mark, > > The "20 dB lower than a K3" figure is an estimate for 100 kHz Blocking Dynamic Range rather than the 2 kHz Narrow Spaced Dynamic Range. > > The K3 is listed at 140 to 150 dB (depending on model, synthesizer, etc) on Sherwood's Receiver Test Data page.?

Everything I had running over win7 runs nicely over win 10. And, win10 seemed run to faster. I did my free upgrade when it was free and haven't looked back since. The big issue I see is learning where win10 puts things and the new format. The setup is not much different, but getting there is. The differences seemed to have caused more heartburn than other issues. However, win10 will support far more things than other operating systems, both long and short term. And if you go with what win10 and your app.exe want, the set is is seriously easy for installs. The only thing hams are going need to learn is where/how to access device manager. It is device manager where you make your com port settings and changes. All else should be a snap. If you have a problem with Microsoft, just do not get an account, skip this in the set up.

Here is the situation: A KPA500 can be connected to a TS-590 COM port. If configured correctly the KPA500 will "poll" the TS-590 once per second with IF;FA;FB;. TS-590 responds with the values of IF, FA, and FB and KPA500 firmware is smart enough to derive the TX band regardless of which VFO is being used as the TX VFO. The KAT500 with firmware 1.34 or later will receive a Kenwood format FA word and will use it to select, not only the tuning solution, but also the appropriate antenna. KAT500 only follows VFO A. It cannot track VFO B and does not know which VFO is being used for TX. I was asked to help another op who, like me, uses TS-590, KAT500, and KPA500. He actually wanted details of my controller but I'm not ready to release anything yet. He had his KPA500 following TS-590 band but the KAT500 only had RF frequency detection. He was sometimes faulting the KPA500 after a band change because the KAT500 had not switched to the required antenna. I told him that it should be possible to make a "Y" cable that kept the TS-590<>KPA500 connection unchanged but which also fed the TS-590 responses to the KAT500. I sent him a draft cable drawing. He reported he had built the cable but the KAT500 did not do any antenna selection when KPA500 and TS-590 changed bands. After a few emails exchanged I decided I had to build and test the configuration myself. It worked as I had expected with KPA500 and KAT500 both following TS-590 band selection when VFO A was the TX VFO. He eventually worked out what he had mis-configured and now has the interface working. Now for the point of this post - Why does Elecraft provide KPA500 firmware that is smart enough to derive TX frequency regardless of VFO selection but KAT500 will only respond to VFO A frequency? Would it not be reasonable to update KAT500 firmware, copying KPA500 code if necessary, so it too will derive TX frequency regardless of VFO usage? I hope Elecraft will consider this to be a useful enhancement that will make it easier to integrate KPA500 and KAT500 with Kenwood rigs. 73, Andy, k3wyc From n1ho at yahoo.com Sun Jun 9 12:10:51 2019 From: n1ho at yahoo.com (Bayard Coolidge, N1HO) Date: Sun, 9 Jun 2019 16:10:51 +0000 (UTC) Subject: [Elecraft] Silent power supply for a K3s In-Reply-To: <000201d51ed2$fecfbbd0$fc6f3370$@w2irt.net> References: <000201d51ed2$fecfbbd0$fc6f3370$@w2irt.net> Message-ID: <1995941851.344056.1560096651632@mail.yahoo.com> I've been running an Astron RS-35A for several years now, fortunately withoutany buzzing. However, I use it to feed a WMR PG40S, which keeps a large (105Ah)AGM SLA battery charged, and that feeds a RigRunner. I adjusted the RS-35A to14.1 V on the RigRunner (on receive), and it dips to 13.5 or so on transmitwhen running the K3 at 100W out. As others have mentioned, it is a case of using large wire - #10 or #8 - in the shortestlengths possible, and the heavier-rated APPs throughout. There are numerous articles out on the web and in the archives of this mailing list aboutamendments to Astron power supplies and depending on the age of yours, you may needto investigate what the root cause of the buzzing is, be it simply loose fastening hardwareor perhaps a filter capacitor that's well past its prime.

The issue you had with the PX3 will not occur with the P3. Yes, you have IQ output on the PX3, but the P3 is the IF output. For the P3 just move the switch on the back of the P3 to enable the P3 IF output, connect it to the SDRPlay, connect the SDRPlay via the USB cable to your PC and Win4K3Suite automatically recognizes the SDRPlay and the spectrum display works right away. No hassles. Yes, you can connect the SDRPlay directly to the IF out on the K3, but why would you do that and loose the use of the P3? As to moving to Windows 10, I don't understand all the hullabaloo. You have to move to it sometime. So, why not do it sooner rather than later. Especially, when it is free. It is my understanding, if I'm wrong someone please correct me, but you will now have to pay to upgrade. For me the upgrade from Windows 7 to Windows 10 has been the least painful of all the OS moves. Yes, you have to get use to things being in different places and accessing things differently, but you've got to do that whenever you move to a new OS. Thus my statement do it now rater than later. There are also new features in Windows 10 that are not in Windows 7 that I think makes it worth it. 73, Mark, WB9CIF -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Gwen Patton Sent: Sunday, June 9, 2019 13:40 To: Elecraft Subject: Re: [Elecraft] K3S - Win4K3Suite - SDRPlay That's essentially what I did, but with KX3/PX3.

He actually wanted details of my controller but I'm not ready to release anything yet. He had his KPA500 following TS-590 band but the KAT500 only had RF frequency detection. He was sometimes faulting the KPA500 after a band change because the KAT500 had not switched to the required antenna. I told him that it should be possible to make a "Y" cable that kept the TS-590<>KPA500 connection unchanged but which also fed the TS-590 responses to the KAT500.

After a few emails exchanged I decided I had to build and test the configuration myself.

I have some pretty old programs that weren't written with Win10 in mind because it didn't exist yet. I'm certain I'll have to upgrade eventually and bite the bullet, but until then it's a balancing act. But to be fair, some of those legacy programs aren't as important now as they once were, so I may be hanging onto stuff I don't need to be concerned with. I'll have to go through the thing and figure out what I need, what I want, and what will still work. Eventually. It's not my #1 priority. I also may have to update the machine at the same time, and there's no sense updating my OS if I'm just going to have to upgrade the hardware. Any new machine I get will likely come with Win10 on it already, so I might as well do a careful software migration to a new box than update the OS on the old box that'll just get set aside. It doesn't owe me anything -- I got this machine 7 years ago. 73, Gwen, NG3P On Sun, Jun 9, 2019 at 12:32 PM Mark Musick wrote: > Gwen, > I have the SDRPlay, Win4K3Suite and Windows 10. > The issue you had with the PX3 will not occur with the P3.

This solves the acoustic noise problem. The new cover looks terrific and is a 1:1 swap with the old one. I went through *exactly* the same problem you describe, and then buying the same replacement supply, then modifying it, ad nauseum, before fixing the original issue. I expect to be able to produce these (it's done on a CNC machine) in the coming weeks. I have several requests already. I do not yet know the cost but it won't be outrageous. Would this interest you?

The problem, of course, is that if the MCU never gets the TTL equivalent of the ASCII request, it won't respond. Hence the issue. What I had hoped to find out is if there's any keyboard or other sequence that would cause the K2 to send data autonomously ... again, without any data prompt. This ability would allow me to show that the TX data side of the setup was in fact operational. I have since that message used an oscilloscope to see that the ASCII RS-232 data **is** getting level-translated and DOES appear on the correct pin of the main MCU, revision 2.04 firmware. I swapped out the v2.04 MCU for an earlier revision chip I had in the junque drawer.. This older chip may or may not have had the same problem.... it's been years since I upgraded to the 2.04 firmware so I do not recall ... and since both MCUs exhibit the same lack-of-response to any inbound serial command, I suspect I need a new MCU, not the Maxim chip.

The problem turned out to be an edge case failure of the USB serial converter. It works fine when DE9 pins 2&3 are strapped (hard loopback) but it doesn't work with the radio. Changing to a real UART port solved this issue immediately. NOW ... the original issue can be addressed! -> The K2 auto-info meta command is *not* sticky. It does not 'stay' across radio power cycles. I had hoped this command would be written into the NV memory chip. Not likely at this stage that Elecraft would issue an updated MCU that did this.

I'm putting these 2 rigs up for sale now and I'll sell the third one after a K4 ships in early 2020. I will deliver within 100 miles of Houston and $50 can be deducted from the prices if I don't have to ship. If an international shipment is needed, let's talk to see how/if that can be done but I'd prefer CONUS. Here is the blurb I'm sending around to see if there is any interest: I took some pictures of two rigs I'm selling now. If you're looking for a used competition grade K3, I think you would like either of these. Be sure and look at the comments beside most of the pictures which tell what I was trying to communicate with each picture. A full "new" pricing estimate is there for comparison and to detail what is in each rig. The actual selling price is listed below. https://photos.app.goo.gl/PQ9aWkhAcXCmnY5i7 This is S/N 752 which has the USB connection (from the KIO3B upgrade) as well as the KSYN3 synthesizer upgrade on main and sub receivers. I'm listing this at $3200 shipped FedEx ground for CONUS. https://photos.app.goo.gl/kbmnKdbEDdJL4hEa7 This is S/N 234 and has the 2 meter module, the K3SYN upgrade (MAIN and SUB), a couple more filters and the general coverage band pass but no USB connection. I'm listing this one at $3400 shipped FedEx ground. Hopefully these links work. My photography skills are not the best but I think someone would get a good idea of the condition of both rigs. Contact me directly with any questions.

There are attempts at replacing those apps, but they're not ready for prime time. I *have* them, but I prefer the Windows originals. I have digital electronics diagnostic tools that simply *refuse* to work with Linux USB drivers. I've tried. Repeatedly. Until I nearly pulled all my hair out. Then I went to the expense and bought that aforementioned Win10 workbench PC...and a 4-channel Rigol oscilloscope.

For the majority of acoustic noise situations in the 35 amp size units (the variable and the fixed voltage models) the height of the steel cabinet is insufficient to keep the sheet metal of the lid away from the flux lines of the transformer. The resulting eddy currents decay and 'fight' against the transformer field itself. This results in the buzzing type hum people experience. Over time this vibration can loosen the transformer windings so it can buzz by itself. But generally, the bulk of the objectionable acoustic noise is from the top cover.. You can confirm the cause by simply removing the cover and operating the supply. There are only seven screws, as you probably already know. Suitable electrical safety precautions are to be taken, of course. If you have a 35A Astron unit and by the above method you can show yourself that the buzzing/hum noise is a result of the magnetic coupling / circulating current scenario I have described, this new composite cover will solve the problem - as well as reducing the obvious waste heat from the supply.

Solution? Message-ID: <000701d51f75$71d24ce0$5576e6a0$@yahoo.com> In the older K3 rigs: What was the old 'solution' to eliminate the initial audio 'pop' when the K3 is turned 'ON' ?? Background: Back in 2009-2010 there was a short list-serve exchange on the topic of the audio 'pop' noise heard when some of the K3 rigs were initially turned on. The noise was described as a simultaneous "double pop" of medium volume heard in the speaker and lasting only a split second, with practically no spacing between the two. Heard in the speaker regardless of the volume control setting. A noise similar to the radio noise of two far-away lightning strikes. Searching those old 2010 exchanges did not turn up a 'solution'. Likewise with the Elecraft site. With that, then, it's easy to 'assume' there is no real issue with the noises, no harm to be expected, no real problem here, let the rig greet the op and say 'hello' in its own way, and let it be. But with masterful electronics, I don't like to assume anything. Did the pops disappear with later production units. If so, was there a home solution, as well?

Maybe try resetting obvious internal cables. The speaker sometimes cuts out on my KX2 after a battery change which seems to be solved by re-jiggering things. Not very scientific but it might work.

Fans are not a problem (actually, I hear nothing from them at all) - IF you design your radio desk for proper equipment placement. Place the power supply at your right hand - and you WILL hear noise, XFMR, fan, etc. It is amazing what proper station design/construction can do for making silence. Open faced metal shelving and bare desktops don't cut it. Just for grins, I put one of those Nanoxia fans in my IC-7300 and silenced it completely. Worth the few dollars and effort. No temperature changes noted. Hmmm - KPA500?????

This happens regardless of tuning step size or VFO A/B choice and does not affect the RIT. A few questions before I tear into it: Do the encoders ever wear out? Has this happened to others, and if so, what have the fixes involved? This K2 has seen a lot of use in the field and mobile as well as at home so humidity- or vibration/shock-induced problems are quite possible. 73, Steve VE3SMA From jfriend31 at comcast.net Mon Jun 10 09:31:03 2019 From: jfriend31 at comcast.net (jack) Date: Mon, 10 Jun 2019 07:31:03 -0600 Subject: [Elecraft] Quiet power supply for K3, etc Message-ID: I have 2 Astron RS-35A power supplies for my two K3 radios.

Those encoders are the optical type and almost never fail. I have seen only one failure in the time I was repairing K2s and I have dealt with over 1000 repairs. I would first reflow the soldering on the encoder wires and Front panel U3 as well as P1, RF Board J7 and Control Board P2. Also reflow Control Board U6 pins 8 and 16. 73, Don W3FPR On 6/10/2019 9:09 AM, Steve Kavanagh via Elecraft wrote: > One of my K2's has developed a problem where it is (somewhat intermittently) unresponsive to turning the tuning knob.

I don't generally want to run the amp on 6m (only if I can't get through with 100W), but I have to have the amp powered up (with its loud power supply fan running) all the time now if I want to see any signals on 6. I'm wondering if it's possible to select the default antenna for when the power to the KPA is switched off? I'd be fine with "last used", and it looked like that was available in the KPA Utilities setting, but as soon as I de-power the KPA, it reverts to ANT-1. --------------------------------------------- 73 and Good DX Peter, W2IRT From pincon at erols.com Sat Jun 8 23:25:53 2019 From: pincon at erols.com (Charlie T) Date: Sat, 8 Jun 2019 23:25:53 -0400 Subject: [Elecraft] P3 Noise band In-Reply-To: References: Message-ID: <007101d51e73$0f03d780$2d0b8680$@erols.com> I've seen that "tracking" type spurious display too, especially when using my old 222 MHz or 432MHz MicroWave Modules transverters and also the internal 2M Elecraft K3 unit. 73, Charlie k3ICH -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Bob McGraw K4TAX Sent: Saturday, June 08, 2019 5:57 PM To: Elecraft Reflector Subject: [Elecraft] P3 Noise band I noticed when working the 6M contest today, I observed a band of noise on my P3.

In a 12 - 14 V supply, this could very well damage anything it is connected to, from a simple 12V light bulb to your fancy new SS radio. That said, many good quality commercial power supplies have what is called a "crow-bar" circuit which is essentially a big SCR across the supply's output, with its gate driven by a voltage sensing circuit set a level slightly higher than the supply's normal output, say 16V. The action is if the regulator fails, the sensing circuit fires the SCR, which is hopefully big enough to effectively short the power supply's output and ether trigger a fold-back current limiting * circuit, or blow a fuse. 73, Charlie k3ICH *Unfortunately, in many supplies, the current limiter AND voltage regulator use the same active device, so in a fault situation, blowing the fuse is the last resort to a safe shut down. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Bert Sent: Monday, June 10, 2019 12:16 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Silent power supply for a K3s How would a switched PS take out a radio?

Linear supplies are particularly susceptible, as the series pass transistor is under stress and can short. Switching supplies can fail if the voltage feedback loop somehow opens up. I've not heard of it happening, but all it would take would be one failed resistor or solder joint. I use a switching supply for my K3, but I built an external overvoltage protector. Of course, the supply has never failed. BTW, I've found that the fan noise from the Samlex SEC-1235 is never audible above the K3 fans, except during long periods of receive, when the low speed supply fan is just barely audible. (I did the mod, so the supply fan runs at low speed all the time.) If I transmit long enough for the supply fan to switch to full speed, the K3 fans are already running fast enough to drown it out. Not to mention those in the KPA-1500. I'm very happy with the Samlex supply.

WSJT uses QTAudio. There are some issues with this QTAudio which sometimes prevents proper enumeration of the audio devices. Unfortunately when this happens, driver enumeration gets "stuck" and will not work properly any longer without a reinstall of Windows. Even uninstalling the offending device driver doesn't work. It still remains in the list. This is purely a bug in QTAudio. Been there, done it. I spent hours with the WSJT developers trying to fix this issue on my system and even though we used many development tools to try and find why, ultimately a reinstall of Windows 10 was necessary. I didn't but the next update of Windows 10, Creators edition, fixed the issue. Now if you are using a microphone input on your sound device, are you sure it's working? It would have to be a stereo input for the IQ signals. Here's a quick test: Pull up the spectrum and turn the VFO A knob on the radio. If you see the signals on the waterfall move in different directions around the center frequency, then you are using a mono feed. 73 Tom Va2fsq.com -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Gwen Patton Sent: June 9, 2019 9:40 AM To: Elecraft Subject: Re: [Elecraft] K3S - Win4K3Suite - SDRPlay That's essentially what I did, but with KX3/PX3. I have a lovely 3.5mm to 2.5mm cable running from the PX3 IQ output to a spare mike in jack on my PC. I had to do some weird jiggery-pokery with default sound devices to get it to work because Win4K3Suite uses some of the same (or related) code that's also in WSJT-X and other code derived from it, that doesn't play nicely with Windows 7 64-bit. None of those programs will "see" my correct microphone list, though other unrelated programs DO. Those programs only see a pair of old entries that haven't been on my machine in years. I have to trick them to see the devices I want, through setting default devices and using VB-Audio's Voicemeeter virtual mixer program. But when I DO get every tab A in the right slot B, I can set Win4K3Suite to look to that spare mike jack for its spectrum scope source. Works great! I've asked (begged) the authors of the various programs to PLEASE do something about their operation with Windows 7, but I only get shrugs and sometimes rude demands that I simply "upgrade to Windows 10, that works". Seeing the *correct* list of enumerated input device drivers should NOT be something I have to upgrade my operating system to get, when I only get the problem with a very small number of specialized programs. *sigh...* 73, Gwen, NG3P On Sun, Jun 9, 2019 at 9:25 AM Don Wilhelm wrote: > Rich, > > There is no need to bypass the P3, just connect the SDRPlay to the P3 > IF output. > > The P3 IF output is a replication of the K3S IF output. > > 73, > Don W3FPR > > On 6/9/2019 7:04 AM, Richard Thorne wrote: > > I'd like to try Win4K3Suite with an SDRplay receiver.

If the KPA1500 uses relays for antenna selection then nothing set in software or firmware can change the state of the relays when there is no power available to energize the relay coils. With no power to the box all the relays (unless mechanically latched) will have continuity between the normally closed (NC) contact pairs. What is it about your setup that would prevent you from swapping the connections between ANT-1 and ANT-2 so ANT-1 is used for 6 m and ANT-2 is used for HF? 73, Andy, k3wyc From lists at w2irt.net Mon Jun 10 13:14:26 2019 From: lists at w2irt.net (Peter Dougherty) Date: Mon, 10 Jun 2019 13:14:26 -0400 Subject: [Elecraft] KPA-1500 antenna selection In-Reply-To: <003001d51fa7$bdc06600$39413200$@comcast.net> References: <003f01d51f9b$f3121c60$d9365520$@w2irt.net> <003001d51fa7$bdc06600$39413200$@comcast.net> Message-ID: <012801d51faf$f585eb70$e091c250$@w2irt.net> Can you tell me more about the power supply mod for the KPA?

I changed out the modification in the Power supply and it quiets the fans quite a bit. Essentially they changed out a 10 ohm resistor to a 22 ohm. It is on the Led board in the Power supply. Took longer to remove the screws than it was to change out the board. I have a Palstar HF-Auto that gives me three positions, so I have my 6 meter beam on 1, Hy-Tower on 2, and an End fed antenna on 3. The Palstar is connected to port 1 of the amp. Since the propagation Gods are not co-operating I have my TH11 on antenna position 2 on the KPA1500. I also stand my Power supply on its end with the fans facing out. The Diawa 12 volt Power supply are louder than the amp's. Probably not what you wanted to hear but what I did works for me. By the way thanks for the FT8 contact during the contest. Ed..

If the regulation series transistor shorts or the regulation circuits malfunctions, then the over-voltage protection shorts the output and blows the fuse(s). My present RS-35M included it in the purchase. Since the late 70s or early 80s, I have used various current rated Astrons in both 12 and 24 volts with few if any issues except when Florida Flash & Flicker passed an EMP or such down the line!

In a 12 - 14 V supply, this could very well damage anything it is connected to, from a simple 12V light bulb to your fancy new SS radio. That said, many good quality commercial power supplies have what is called a "crow-bar" circuit which is essentially a big SCR across the supply's output, with its gate driven by a voltage sensing circuit set a level slightly higher than the supply's normal output, say 16V. The action is if the regulator fails, the sensing circuit fires the SCR, which is hopefully big enough to effectively short the power supply's output and ether trigger a fold-back current limiting * circuit, or blow a fuse. 73, Charlie k3ICH *Unfortunately, in many supplies, the current limiter AND voltage regulator use the same active device, so in a fault situation, blowing the fuse is the last resort to a safe shut down. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Bert Sent: Monday, June 10, 2019 12:16 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Silent power supply for a K3s How would a switched PS take out a radio?

I'll probably go the same route with the K4. She and I are moving into a retirement community in Peterborough NH which is just down the hill from the old family house on 6 acres. One option will be to put a K4 there and operate remotely from the community, avoiding all the noisy switched mode power supplies.

When I have this situation with other receivers/transceivers I find I can shift the BFO or Carrier Oscillator on the filter slope and get audio that I like. I also changed capacitor values in the audio stages too. With the K2 I've tried other speakers and not found the sound that I like. I am also a little intimidated about any changes around the filter in the K2, since I don't have the spectrum displays that are recommended for exact adjustment.

Use Spectrogram for a visual indication of the filter passband. See http://www.mmccs.com/mmarc/n0ss/k2_filters_using_gram_v5r17.pdf. You will not be disappointed. If you need Spectrogram, go to my website www.w3fpr.com and scroll down on the home page to near the bottom. You will find links to both version 5.17 and version 16. 73, Don W3FPR On 6/10/2019 7:52 PM, wes Bolin wrote: > I have a very nice K2 that I bought as previously owned.

The larger fans in my KPA1500 are quiet.? ?Any noise is at low freq. Do you work keydown modes at high duty cycles, like RTTY contesting or WSJT-X modes where high power is needed (6M, 160M, for example)?? If you do a lot of meteor scatter or FT8 or moonbounce, especially on 6M where the efficiency is lowest, it doesn't take long for the fans to scream. And that's because they are small, which they must be to fit in the height dimension of the power amp. 73, Jim K9YC From P.Hall at curtin.edu.au Tue Jun 11 03:54:04 2019 From: P.Hall at curtin.edu.au (Peter Hall) Date: Tue, 11 Jun 2019 07:54:04 +0000 Subject: [Elecraft] KPA1500 Power Supply Fan Noise In-Reply-To: <1123614303.1123286.1560211022719@mail.yahoo.com> References: <1123614303.1123286.1560211022719.ref@mail.yahoo.com> <1123614303.1123286.1560211022719@mail.yahoo.com> Message-ID: Hello Eric There's no doubt that a KPA1500 physical installation needs some careful attention to the noise aspect. That said, I'm a bit surprised by your problem with the PSU fan. I can certainly hear mine but, overall, the noise is entirely dominated by the RF deck fans. I've located the PSU under my operating desk, which is made of a dense particleboard material. The RF deck sits alongside my TS-890S transceiver on the desk. I can hear the PSU fan if I put my head below desk level but, even then, I don't find the fan to be particularly high-pitched in its acoustic output. Could you possibly have a faulty fan (maybe excess nearing noise)? On the other hand, I do find the RF deck fans test my patience a bit, especially since the last round of major firmware updates which start the cooling at a lower heatsink temperature. That probably works well in a high-output environment, where it no doubt delays the onset of heat soaking. But when the amplifier "loafs" in a low power, low duty cycle environment as it does in some of my applications. it just starts the noise prematurely. It'd be great to see something like an "80m rag-chew" option for those times! 73, Peter (VK6HP). -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of eric norris via Elecraft Sent: Tuesday, 11 June 2019 7:57 AM To: lists at w2irt.net; lists at w2irt.net; Elecraft Reflector Subject: [Elecraft] KPA1500 Power Supply Fan Noise More broadly, has there been any progress on reducing the piercing power supply fan noise on the KPA1500 when only using it as a tuner or an antenna switch??

I have the fan speed on the RF deck set to 2 as a minimum. I almost never notice the PS fans, when I hear noise it is the RF deck. During the ARRL DX CW the fans reached 4 and it was loud enough to need headphones, in most operation it is not. The PS noise you are describing does not seem normal to me. Can you make a video/audio recording and post it on the web somewhere? 73 John N5CQ -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Eric Norris Sent: Tuesday, June 11, 2019 3:47 AM To: Peter Hall Cc: elecraft at mailman qth. net Subject: Re: [Elecraft] KPA1500 Power Supply Fan Noise Apparently I was not clear enough in my message.

The fans in my PSU are pretty quiet, but nevertheless the KPA1500 PSU is remote-installed in a closet in my shack. I am absolutely no "audio" guy, but years ago installed a free, cheap & dirty noise level meter app on my android phone called "Sound Meter." I use it to complain to restaurant managers that the blaring music in their establishments is too loud for casual conversation, demanding that it be turned down. With the KPA1500 turned off and phone situated 3 feet from the power supply, the noise level in that closet is 28 DB. Turning on the amplifier raises the noise level by 12 DB to 40 DB - a 12 DB difference. Not much difference, and certainly not the "piercing power supply fan noise" you describe. -larry (K8UT) ------ Original Message ------ From: "eric norris via Elecraft" To: "lists at w2irt.net" ; "lists at w2irt.net" ; "Elecraft Reflector" Sent: 2019-06-10 19:57:02 Subject: [Elecraft] KPA1500 Power Supply Fan Noise >More broadly, has there been any progress on reducing the piercing power supply fan noise on the KPA1500 when only using it as a tuner or an antenna switch? I complained about this a year ago, and I find it completely unacceptable. No set of noise-reducing headphones that I have tried works well enough to make the noise tolerable. I've tried moving the PS deck around with minimal improvement. This just doesn't seem to fit Elecraft's philosophy of a quiet operating environment. Why do these fans have to operate at full throttle when there is minimal current draw from the rf deck? Why do these fans create such a piercing high-pitched note? >If there is no response from Elecraft, what have other ops done--short of moving the PS into an adjoining room--to mitigate the scream? >Thanks, >73 Eric WD6DBM > >Sent from Yahoo Mail on Android >______________________________________________________________ >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 k8ut at charter.net From hlyingst at yahoo.com Tue Jun 11 09:03:55 2019 From: hlyingst at yahoo.com (Harry Yingst) Date: Tue, 11 Jun 2019 13:03:55 +0000 (UTC) Subject: [Elecraft] STRAIGHT KEY WIRING-KX3 - Dress up the wire In-Reply-To: References: <20190610.195411.30119.3@webmail10.vgs.untd.com> Message-ID: <1729445934.1357171.1560258235080@mail.yahoo.com> To dress up the wire on my key I took a piece of black parachute cord and pulled out the center strands.

Currently, I use DXBase for logging and an SDR-IQ running SpectraVue software for a panadapter.? These are "connected" to the K3S using LPBridge for port sharing.? This works well, and provides a clean spectrum display with point-and-click and mouse wheel tuning, if desired. I can also connect N1MM and AXTTY (a DXBase specific version of MMTTY) via port sharing if necessary. I don't use skimmer, spots or any of that other stuff. Enter FT8, which for philosophical reasons I'm not fond of, but pragmatism is forcing it on me.? As best as I can determine, WSJT-X (FT8) requires total hogging of the K3S com port.? So to switch over I have to close the other programs and start WSJT-X. This takes a little time while DXBase updates its database.? Going the other way takes even more time while LPBridge creates the virtual ports before the other programs start.? Although I haven't tried it I believe there is a bridge from WSJT-X to DXBase, which then gets frequency from WSJT-X. So, the question is, is there a solution to this other than buying a different radio? Wes?

Then see if you get a good response in CW. Oh BTW, make sure the CW filters are centered at your sidetone pitch first - use an audio spectrum analyzer and if you have one, a broadband noise generator (if not, use band noise, but make sure there are on signals on the band segement used). If the CW filters work OK with the KSB2 removed, the troubleshooting should start with the switching diodes on the KSB2 option. 73, Don W3FPR On 6/11/2019 2:53 PM, Bill Coleman wrote: > OK, I have a K2/100 w/ KAT100 that may have recently suffered from a static discharge event.

I haven't experienced that with my MH4, in fact with my recent order for a K4, I ordered an additional MH4 so I can have one with the K3s as well. But as to repairing plastic cracks, depending on where they are, you might want to get some plastic epoxy and repair from the inside. Nothing will make the crack disappear but you'll stop the old ones from expanding. Do it from the inside will be the cleanest way. A couple days ago I picked up a plastic funnel where it has sat since last fall. I used the tab on its edge to pick it up, the funnel fell off, breaking at the tab. Plastic just won't ever last. 73, Gary KA1J > I'm now on my second MH3 mic for KX3 and discovered it too has several > cracks in the case.

In-Reply-To: References: Message-ID: I believe the KX3 does have a diode in the line. Bottom line, the radio doesn?t care what your Fluke says, it uses its own voltmeter and acts on it. I owned a KX3 for a while and felt a bit behind as the radio was introduced with NiMH battery technology just as LiPO battery technology was just coming into full bloom. If the voltage range were just bumped up to 16-17 Volts. A nice 4X? Pack would be great. A 3X pack is barely enough. Think the KX2 is now a better deal. But my portable days are over. Sadly.

I quickly found out that it does not pass all commands through the radio. In addition, there were many cases of collisions between software products if they tried to write to the comport at the same time. So, a long story short, I developed Win4K3Suite. It is completely different than passive comport sharing utilities. It has 6 "Virtual radios" that act pretty well identical to the K3, KX3 or KX2. It listens to commands from software products and then delivers results either from memory or if a write is necessary, then all threads are synchronized and prioritised so that one application cannot clobber the other. You can run 6 applications simultaneously as well as HRD Logbook. It also works with hardware devices like SteppIr antennas and tuners. Here is a video from Max, NG7M who uses it extensively to connect all kinds of software and hardware together. https://youtu.be/zbf7BPfcj4U It does use com0com, but not as a sharing tool but rather com0com actually behaves just like a null modem cable. You create a Pair of comports which form a null modem cable and you connect one side to Win4K3 and the other to the other software. It is 100% reliable and tested with thousands of users. There's a free trial and updates are free. There are numerous videos under Documentation, Video Tutorials. In any case, I would not use HamLib for connections. Always use Omni-rig. Much more stable. 73 Tom Va2fsq.com -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Wes Sent: June 11, 2019 2:47 PM To: Elecraft Reflector Subject: [Elecraft] K3 port sharing and FT-8 Maybe the collective wisdom of this group has an answer not to be found elsewhere.

Going the other way takes even more time while LPBridge creates the virtual ports before the other programs start.

However, It is a fact that more than a few ops using WSJT-X mode generate huge audio harmonics because they don't use "split" and don't set up the audio drive correctly. 73, Andy, k3wyc From Gary at ka1j.com Tue Jun 11 20:01:02 2019 From: Gary at ka1j.com (Gary Smith) Date: Tue, 11 Jun 2019 20:01:02 -0400 Subject: [Elecraft] K3 port sharing and FT-8 In-Reply-To: References: Message-ID: <5D0040BE.5487.32757E0D@Gary.ka1j.com> With the K3 & the K3s, I found getting WSJT-X to play nice was an oddity; 5% of the time it would work and 95% of the time it did not (The % is relative to my experience, not exact %).

I was not happy with several things regarding WSJT-X and I could see people asking for the same things on the email forum but these changes didn't come. A VE friend suggested I try JTDX and though it does not do some things I like, like MSK for 6M, I found it to do everything I liked and it has much the same interface as WSJT-X. It is also a free program and now that I am using it, I no longer use WSJT-X, for me, there's no need to. http://jtdx.tech/en/videos-guides Look to the bottom of the downloads column on the right & the latest version for windows is JTDX v2.0.1-rc137_6 My 2 pence & 73, Gary KA1J > Maybe the collective wisdom of this group has an answer not to be > found elsewhere. > > Currently, I use DXBase for logging and an SDR-IQ running SpectraVue > software for a panadapter.?

Plus not all sound card responses are 'flat' so the levels, if outside the tested range (say 1500 Hz +/- 500 Hz) vary much, it may be too loud (overdriving) or soft. A simple test, into a dummy load, set your audio tone for a lower tone, watch the output, repeat with a mid-range tone and a higher pitched tone.? If you don't have to readjust the audio drive to the radio (while keeping NO ALC), you're fine.? If you do have change levels, use the frequency shifting of WSJT-X to stay within the same range.

The ALC scale on the K3/K3S/KX3/KX2 gives you the ability to adjust the audio level (the lower bars are NOT an indication of ALC). ALC begins at the 5th bar. Those Elecraft radios must be have the audio level adjusted so there are 4 bars solid with the 5th bar flashing. The Elecraft radios must not use the audio level to control power - other radios may use that method, but not Elecraft. If you want full information about that (and the related Elecraft power control), refer to the article on my website www.w3fpr.com.

We can hope that perhaps some day Meanwell will switch to a temperature controlled fan. I don't find mine particularly loud, as the RF deck fans drown them out even at their lower speeds. Even the K3 fans will drown it out when I'm running in a CW contest. I use some very good passive headphones, however. I don't think it's realistic to expect to be able to operate with an amplifier in the shack without headphones. However, the KPA1500 is fully capable of remote operation, so you could put it in the next room. 73, Scott K9MA On 6/10/2019 18:57, eric norris via Elecraft wrote: > More broadly, has there been any progress on reducing the piercing power supply fan noise on the KPA1500 when only using it as a tuner or an antenna switch??

George) Date: Tue, 11 Jun 2019 22:03:54 -0600 Subject: [Elecraft] K3 port sharing and FT-8 Message-ID: Wes, I wanted to jump in where Tom mentioned my YouTube video of sharing Virtual K3 CAT feeds with Win4K3Suite . I'm just like you, I like to turn the knobs primarily. Don't be confused by the graphical interface that Win4K3Suite provides as it relates to sharing your K3/S CAT feed. Early on I purchased the software primarily for the ability to share full on Virtual CAT Feeds and not the graphical interface. The CAT sharing is just one aspect of Win4K3Suite. The PAN Adapter support and graphic interface are simply additional features you can use if you like. And for remote operation the graphical interface is excellent as you will learn if you operate remote. Or just minimize Win4K3Suite and don't use it... twist the knobs on your radio and just use the CAT sharing via the Virtual K3 CAT feeds it provides. I would highly recommend that you watch my video. It's very detailed... to a fault some will say, but you can jump ahead by 10 seconds and back using the L and J keys and pause with the K key. Or jump ahead 5 seconds and back with the arrow keys and pause with the space bar. I too used LP-Bridge many years ago and it did work, but it isn't even in the same ball park for reliability as Win4K3Suite for sharing CAT Feeds. Not even close. The beauty of :Win4K3Suite is that it creates true Virtual K3/S CAT feeds. The software or hardware you are using has no idea it's not connected directly to the K3/S CAT port / USB CAT port direct. No funky API's like Hamlib or Omni-rig that requires software support to use the abstraction layer required. If there is hardware or software that expects to be connected directly to a K3/S CAT port / feed, it will work with Win4K3Suite Virtual K3/S CAT interfaces. Watch the video and give Win4K3Suite a try. The com0com port setup trips most guys up, but you have the same problem with LP-Bridge too. I go into great detail on com0com in the video. It's not bad once you understand the concept. You won't go back to LP-Bridge... my two cents. And again, you are not required to use the graphical interface to the K3 for anything, but you might just start using it after awhile, for remote control like I did. Not to mention all the other features... like using it with LP-PAN2 or SDRPlay. I switched from NaP3 long ago and never looked back. By the way, i'm a big N8LP fan too... I love the LP-PAN2 setup and LP-700, but NaP3 plays second fiddle to Win4K3Suite's spectrum display and you can now pump a UDP feed of the spectrum to N1MM too... Have fun.

Rick, You (or at least your test) are (is) blaming the computer sound card for what may also be the response of the?TX bandpass filter. I would be VERY surprised if the response of a sound card varied more than a few dB from 200-3,000 Hz. If audio levels between the computer and the radio are reasonably set, a few dB is not going push the system into distortion. It's common for RF, digital, and video engineers, whose signals are at generally fixed levels, to fail to understand that analog audio is NOTHING like that. Indeed, the level of ordinary voice signals varies over a range of at least 30 dB. In analog systems, levels are set so that peaks always stay comfortably below clip, where distortion rises sharply. My recommended methods of setting the output levels of sound cards all boil down to one principle -- set the output of the sound card at least 6dB below where it starts to sound distorted. Very easy to do, at least three ways. 1) Use your ears -- plug headphones into the computer output, activate "Tune," start with the Power slider fairly low and increase it until the tone starts to sound harsh. THAT'S distortion. Now, back off the Power slider until it sounds half as loud. That will bring it 7-10 dB lower. Run the sound card there. (This works because humans perceive 7-10 dB "half as loud" or "twice as loud." 2) Use a scope to find clip by seeing flat-topping of the sinewave, then back down to at least half the voltage, or maybe slightly more. 3) Use a voltmeter to find where the voltage stops increasing with the Power slider, then it down so that the voltage is half or less of the max value. Once you've done this, the sound card should safely drive a line level input without overload, and audio transmit level can be set just like you would with speech. If the radio has no line level input, you simply build a 20 dB voltage divider, (470 ohms in series between computer and rig, 47 ohms in parallel with the mic input). or 1K and 100 ohms. This is all very simple, it's stuff that we demonstrated that we learned when we passed our license exams. 73, Jim K9YC From k9ztv at socket.net Wed Jun 12 04:40:00 2019 From: k9ztv at socket.net (K9ZTV) Date: Wed, 12 Jun 2019 03:40:00 -0500 Subject: [Elecraft] AX1 SOTA In-Reply-To: <53323231-DE33-4AA9-ACE3-779F8E925F18@arrl.net> References: <53323231-DE33-4AA9-ACE3-779F8E925F18@arrl.net> Message-ID: <9890F7BE-0ECE-4DDB-88AB-E0B87FDFFAA8@socket.net> Same date, same rig, same antenna, same band at ground level on a state park picnic table at 700-feet altitude, 30-feet from parking lot (my idea of hiking) ...

I use Win4K3 whenever the K3 is on in the shack, but seldom use its graphical interface. The virtual radio concept works extremely well. As he said, software that expects to connect directly to the K3 has no idea that Win4K3 is there. I did find one caveat to this while testing it during my trial period... I used to send CW from the computer by toggling DTR on the K3 serial port. With Win4K3 in the mix, this did not work. Tom told me that direct control of those hardware handshake lines was not supported. I was so happy with everything else it does that I bought it anyway and switched to using a winkeyer. I don't know whether that limitation still exists or not...just throwing it out there in case it matters to your use case. On Tue, Jun 11, 2019 at 11:05 PM M.

Wes, I don?t run the other programs you?re using with FT8 (I use JTDX, but it interfaces the same WSJT-X), but with LPBridge connected I?ve had no issues communicating with my K3S and other programs. If you haven?t tried them yet, download Joe?s (WA6AXA) WSJT-X and JTDX bridge interfaces. I discovered the bridge will load the last FT8 QSO into DXBase even when DXBase isn?t connected to my K3S. So your FT8 program can be a port hog but you can still log QSO?s into DXBase. 73 Lou, W0FK ----- St. Louis, MO "The difference between stupidity and genius is that genius has its limits."

When I was running AFSK, I would use the standard tones 2125/2295, set the levels on the K3 with 4 bars showing, the 5th flickering (no ALC).? But if I tapped the display (in HRD) to center on another station (changing tones to say 1000/1170) I often noticed that the bar display was often very different, either pegging the 5th bar or not even reaching the 4th bar.? Adjusting the Mic gain was the simple fix, but it was something that had to be watched for each click of the mouse. Based on the assumption that it wasn't the K3 as the cause, that leaves the computer (no equalizer in play, so not likely) or the sound card (in this case a SignaLink). It's not scientific research but there you are. I don't have the training or tools (scopes) to make refined repeatable lab quality observations of audio.? It also stops the K3 from power hunting if you watch the audio levels (rarely saw that, even with 3 bars showing, even the amp stayed at full power). These days I use FSK and manually tune so this is a non-issue for RTTY but having experienced this before, I watch carefully on FT8 (and it doesn't seem to be an issue since I use 'fake it' which keeps the actual tones between 1500-2000 Hz. and I'm unlikely to transmit harmonics of the audio). 73, Rick NHC On 6/11/2019 11:07 PM, Jim Brown wrote: > On 6/11/2019 5:42 PM, Rick WA6NHC wrote: >> A simple test, into a dummy load, set your audio tone for a lower >> tone, watch the output, repeat with a mid-range tone and a higher >> pitched tone.?

I got the K1 about 19 years ago, and the AX1 is my most recent toy from Elecraft Land. I have many toys from that land, so a few weeks ago I was taking my son to have his 12 mile run in a park here in NJ, and I thought I'd sit at a picnic table and try to make a few contacts. The K1 was the easiest to disconnect from my setup, so I grabbed it, a small 12v battery, and the AX1 for about two hours of playing in the WPX cw contest. During that time, I made 28 contacts (of course all were 599) on 20 and 15 running 5 watts. Many over 1000 miles in distance. What a rush! My only problem was how to connect the radial to the K1 since it has no easy ground connection. Solved by connecting the radial to the nut that holds the antenna connector to the case of the rig. A great day. There is serious mojo in both those products, I would never have believed that the AX1 would work that well. Nice to keep learning new thing, not only by following the list, but getting inspiration and acting on it as well.

Fortunately, all applications that I am aware of support software PTT or allow you to use a different comport for PTT. You can make such an adapter easily with one resistor and a transistor on an RS232 port. In the case of N1MM+, using DTR to send CW when there are 6 other applications running is impossible since it relies on precise time for the dit's and dah's. So the solution is a WinKey for CW. You can buy one for under $40 these days and well worth it. 73 Tom -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Dave Fugleberg Sent: June 12, 2019 9:08 AM To: M. George Cc: Elecraft Mailer Subject: Re: [Elecraft] K3 port sharing and FT-8 I would echo what Max said. I use Win4K3 whenever the K3 is on in the shack, but seldom use its graphical interface. The virtual radio concept works extremely well. As he said, software that expects to connect directly to the K3 has no idea that Win4K3 is there. I did find one caveat to this while testing it during my trial period... I used to send CW from the computer by toggling DTR on the K3 serial port. With Win4K3 in the mix, this did not work. Tom told me that direct control of those hardware handshake lines was not supported. I was so happy with everything else it does that I bought it anyway and switched to using a winkeyer. I don't know whether that limitation still exists or not...just throwing it out there in case it matters to your use case. On Tue, Jun 11, 2019 at 11:05 PM M.

Sometimes control buttons fail to work due to the ribbon cable connecting the two halves of the KX3 becoming loose or developing bad connections. Opening the KX3 and unplugging/replugging the cable at both ends frequently fixes this class of problem. Using a contact cleaner on the cable contacts may also help. 73 Bill AE6JV ------------------------------------------------------------------------- Bill Frantz | When it comes to the world | Periwinkle (408)356-8506 | around us, is there any choice | 16345 Englewood Ave www.pwpconsult.com | but to explore? - Lisa Randall | Los Gatos, CA 95032 From donwilh at embarqmail.com Wed Jun 12 19:55:38 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Wed, 12 Jun 2019 19:55:38 -0400 Subject: [Elecraft] Silent power supply for a K3s In-Reply-To: References: <642513742.653440.1560145810065@mail.yahoo.com> <98b78783-4803-656c-b810-6e935faa71a6@nycap.rr.com> <86C03DCE-DDCC-4A41-A1F3-6A422C343809@gmail.com> <7b6b602c-a4fc-03bc-3724-d7327e206375@n7xy.net> <816154809.372517.1560345474679@mail.yahoo.com> <09473355-b170-e5c1-f54b-79bed698d38c@bell.net> Message-ID: <8e6396b4-e757-68c6-541f-b08e6c049a49@embarqmail.com> After consulting copper wire tables and typical connection resistances, I can present the following analysis for a 20 amp load: Often hams power their 100 watt transceivers through DC distribution devices such as a RigRunner which will contribute to the voltage drop. Also in-line fuses will contribute to voltage drop. Connection resistance contributes .05 volt loss under a 20 amp load for each contact point, you have 6 contact points in the path for a fused RigRunner plus two in the APP connector at the transceiver, plus the connection to the power supply for a total of 10 contact points. You have to consider the negative path as well as the positive. So that is a total of 0.5 volts of the total voltage drop. By contrast, a 5 foot length under a 20 amp load of #12 wire has 0.1588 ohms (in both conductors) for a voltage drop of 0.3176 volts, and #10 wire a drop of 0.1998 volts. So conclusion is that while increasing the wire size can reduce the voltage drop, the main contributor is in the power distribution system. A path direct from the power supply terminals can be expected to have a 0.5 volt drop with 5 feet of #12 wire to the inside of the K3. and #10 wire can have a 0.4 volt drop - the difference is only slightly significant. Conclusion - in a 5 foot power cable run, the difference between #10 and #12 wire is only 0.1 volts (0.05 volts in each of the positive and negative leads) - the major contributor is the number of contact points. So for those who choose to measure the voltage drop from the power supply terminals to the APP connector on the outside of the K3, you should measure about 0.2 volts in each conductor with #12 wire and 0.15 volts with #10 wire. If it is much more than that, check your power supply connection tightness and your crimp connections. Run the transceiver direct from a power supply using ring terminals instead of routing through a power distribution accessory. 73, Don W3FPR On 6/12/2019 6:29 PM, Bob McGraw K4TAX wrote: > Regarding "heavy gauge wire", I suggest one measure the voltage drop > using a DVM connected direct between the power supply Pos terminal and > the radio Pos terminal.??

This assumes the APP connections into and out of the RigRunner are assembled correctly (contacts properly aligned). If they are not, the contact resistance will be significantly higher. Further, the 20A current (and the voltage drop I^2*R) may be significantly higher in the cable between the power supply and RigRunner. Again, this will result in *MORE THAN* 0.5 volts of total voltage drop when using a RigRunner type power distribution system. Further, while one may measure 20A in transmit (using the K3 internal "meter") there is a significant time constant, particularly in SSB operation. The actual *peak* current may be closer to 30 - 35A than to 17 - 20A. Since voltage drop in power supply cables and power distribution system are related to the *current squared* the actual *maximum* voltage drop (and loss of voltage regulation, increase in transmit IMD, etc.) will be worse that the static analysis would indicate. 73, ...

If that does not cure anything, then proceed with the rest of the alignment, but I doubt if that will help much - the K2 alignment is usually quite stable over time. The bandpass filter and other alignments are not going to change the relationship between the SSB filter and the CW filter - only CAL FIL will do that. If you still have a problem after the full CAL FIL, you will usually find a problem in the CW filter bank - like a bad crystal (but that does not happen often).?

First, are you hearing general band noise, a constant ? shhhhhhhhhhhh? or pulses as in lightning, power line, or ignition type noise. For band noise, the NR will be your best solution. Experiment, but don?t go too deep. Deep settings will distort and make it sound like you?re underwater. For the pulse noises, try IF first, again don?t use extreme settings. If this doesn?t work, try the DSP settings and see if this will work. I have NB set to Med4. NR is set to F1-3. YMMV. Have fun!

A big PSU dedicated to the rig(s), implementing "Remote Sensing" so at a distribution point close to the radio(s) the DC voltage is held constant, irrespective of the cable length from the PSU. This power supply should have a proper overload (and over voltage) protection scheme too, not only to protect itself, but the radio(s) also.? And safety resistors between + and +s, also between - and -s terminals.? (Prevents expensive embarrassment, if a sense line fails!) Then use a smaller PSU for the low power accessories, with suitable fusing. Any QRO power amp, needing really high current, should have it's own independent dedicated PSU, again with remote sensing to keep the voltage at the PA as near constant as it can be, and the resulting high DC currents, purely between the PA and it's PSU. Just my way of doing things, to keep the high DC currents out of the RF cabling. Google "power supply remote sensing" for more info. 73.?

Lightning and atmospheric is random noise. As to the Noise Reduction, I find that use of the Attenuation and RF Gain control is far superior to using DSP systems.? Also remember it is Noise Reduction and not noise elimination as many seem would like to believe.? If one realized 6 dB of noise reduction using the system that's good.?? At the same time, any noise reduction system will add distortion to a SSB or CW signal. From very authoritative source, the optimum receiver performance configuration is to have the no signal band noise about 10 dB above the noise floor of the receiver.??? Since we can't change the noise floor of the receiver, the option is to change the incoming level of the noise as presented to the receiver input. The K3S receiver noise floor is about -135 dBM.?? If one has a no signal band noise of S-5 or -97 dBm, the difference is 38 dB. This says we need 28 dB of Attenuation and RF Gain reduction.??? That would be 15 dB of Attenuation and about 2 S units of RF Gain reduction or 10 dB of Attenuation and about 3 S units of RF Gain reduction.???? This in no way changes the sensitivity of? the receiver nor does it impede the ability to hear weak signals. Unfortunately many hams belie that more gain is needed to hear weak signals.?? With receivers of 50+ years ago often the receiver noise exceeded the band noise.? That however is not true with today's modern receivers. As to using the Noise Reduction,? I do not use it at all for SSB and for CW. ? If? I do use it I find? F1 and a value of 1 to 3 about all I'm willing to accept.? Of course the type and magnitude of the noise does require different settings. If I use the Noise Blanker I find it necessary to first set the IF NB to OFF.? Then adjust the DSP through its values to get what seems to be the best result.? Remember the value.? Then set the DSP NB to OFF. ? Then to the IF noise adjustment and find what seems to be the best result. ? Leave it at that and then back to the DSP Noise blanker and set it to the previous obtained value. ?? This optimized them individually. ? I've not been successful in trying to adjust both at the same time. ?? And remember it only works on repetitive noise such as ignition noise or line noise and not random atmospheric noise. The receiver gain method works best.?? Hope this helps. 73 Bob, K4TAX On 6/13/2019 6:43 AM, Nr4c wrote: > This is not an easy thing. > > First, are you hearing general band noise, a constant ? shhhhhhhhhhhh? or pulses as in lightning, power line, or ignition type noise. > > For band noise, the NR will be your best solution.

A Power out problem #2438 In-Reply-To: References: Message-ID: <14284cc2-8893-5f66-6739-32a535a25a80@embarqmail.com> Jim, Can I assume this is a newly purchased kit? Or are you building an older one that has been sitting on someone's shelf for a long time with Rev A boards. A serial number would be helpful - above SN 2999 will use Rev B boards. Given that you have 1.4 volts on the base of the PA transistors, you likely have one PA transistor zapped and the other may be weak. Get the K2PAKIT from Elecraft (it contains matched PA transistors). It also has replacements for Q11 and Q13 if needed and a replacement for R50 if yours is not already 1/2 watt. It also contains new PA standoff mounting hardware. First remove the PA transistors. If you do not have good removal tools, clip the leads near the transistor body and remove the leads one at a time. Clean up with solder wick and if solder remains in the holes, heat the solder pad and push it out with a wooden toothpick. Now do a TUNE and measure the voltage at one of the base solder pad. It should be 0.60 to 0.64 volts (0.8 volts is too high) If it is not within that range, replace Q11 and Q13 and reflow the soldering on the components in the bias circuit. Do NOT install Q7 and Q8 until the base bias circuit is working correctly. After those checks (and only after), install Q7 and Q8. Do not transmit without the heat sink installed if you value your new PA transistors. If this is an older Rev A kit, how many turns did you wind on L25 and L26? The older Rev A uses 14 turns which is different than the newer kits. 73, Don W3FPR On 6/13/2019 3:33 PM, Jimithy66 wrote: > I finished building a basic kit with no options and the power output will > not rise above 2 watts and current (2A) is too high for that power. > Hi Cur flashes briefly before power output settles at 2 watts. > > Voltage checks found the PA base bias circuit putting out > 1.4 VDC but 0.8 V is expected. > > Two PN2222A transistors Q11 and Q13 make up > the bias circuit and wonder if anyone else remembers > seeing this problem, and what may have caused it ? > > Thanks, > > Jim / W1FMR From ed at w0yk.com Thu Jun 13 17:42:54 2019 From: ed at w0yk.com (Ed W0YK) Date: Thu, 13 Jun 2019 14:42:54 -0700 Subject: [Elecraft] K3S soundcard after Windows 1809 update In-Reply-To: <000501d5221f$c6020790$520616b0$@n7us.net> Message-ID: It just so happens I was at Elecraft a couple hours ago testing a K3/KIO3B with a Win10 1903 notebook and a Win7 notebook.?

In the first sentence, you say you can achieve 4 bars with the 5th one flashing. Then in the 2nd sentence, you say that you cannot achieve that same condition. Are you aware that if you overdrive the KX2/KX3 audio with too much input, the KX2/KX3 will shut down the audio amplifier. It may be that you are driving it with too high an audio level. Back down on the computer generated audio and see if things are restored to normal. 73, Don W3FPR On 6/14/2019 9:23 AM, MaverickNH wrote: > I'll add that, with Win10 volume mixer sliders set at 50%, WSJT-X slider set > to 50%, MIC GAIN is at 3-4 to get 4 bars with 5th flashing.

In the first sentence, you say you can achieve 4 bars with the 5th one flashing. Then in the 2nd sentence, you say that you cannot achieve that same condition. Are you aware that if you overdrive the KX2/KX3 audio with too much input, the KX2/KX3 will shut down the audio amplifier. It may be that you are driving it with too high an audio level. Back down on the computer generated audio and see if things are restored to normal. 73, Don W3FPR On 6/14/2019 9:23 AM, MaverickNH wrote: I'll add that, with Win10 volume mixer sliders set at 50%, WSJT-X slider set to 50%, MIC GAIN is at 3-4 to get 4 bars with 5th flashing.

Elecraft radios control power differently from all other amateur transceivers (some commercial transceivers use a similar method) - so ignore that internet advice.?

However, last year we were limited to less than 50-feet separation and I noticed the Carrier Operated Relay (COR) in my K3 was kicking on occasionally from the SSB station with which we (CW) were obliged to share a trailer. I tried a TRP-150 for the first time on the air this morning and a station in Michigan detected no clicks, truncating, or other aberrations. We'll see. 73, Kent?

That is not how noise blanking normally works; normally it will suppress any wide band pulse. The typical arrangement uses a high bandwidth, low delay, path, to detect the pulse. It can then mute the signal path by the time the pulse gets through the narrower filters on the main path. That will happen with single, or randomly spaced spikes. -- David Woolley K2 06123 On 13/06/2019 14:09, Bob McGraw K4TAX wrote: > The Noise Blanker only affects repetitive pulse noise such as ignition > type noise.?

That would do it. And could the SSB station be pushing the power and ALC and compression thus likely causing distortion and splatter? That would do it. One of my major pet gripes for net control operators and contest operators is the fact they believe turning things up a bit with the thinking they will be heard a bit better When in fact they are making their signal more difficult to copy. If their station sounds good during SSB rag chew QSO's the the same settings should also be good for contests, Field Day, and when a net control.

The mF#-# settings mix unprocessed signal with the NR processed results. the second # sets how much. The wider IF bandwidth lets the NR work optimally on random, uncorrelated noise while the APF pops the desired signal out of the muddle the NR makes. Tune carefully using the FINE tuning rate, the APF is very narrow. There can be no other stronger signals in the IF passband. I haven't had much success using the DSP NB. The IF NB works well on pulse noise and some powerline noise but if there is a very strong signal nearby it will create some nasty artifacts. 73, Brian, K0DTJ KC6CNN wrote .....

Actually now that I think about it, I have another nit.? Although the control on the K3 front panel says "RF Gain", which I guess differentiates it from AF Gain, it really should say "IF Gain".? It has absolutely nothing to do with affecting the gain ahead of the i-f amplifier.? Front end attenuation can affect noise power into preamp and/or the first mixer (and noise blanker circuit); "RF Gain" cannot.? In fact RF Gain is applied first to exactly the same point as AGC, the post-filter FET.? The FET can't tell the difference, which might be news to the guys who turn off the AGC and "ride the RF gain control." Wes?

And some from work done by Art Collins and company at Collins Radio.? They prescribed the function of a Noise Blanker as follows: "The following operational requirements were kept in mind: 1. Reduction of ignition noise from vehicles. 2. Reduction of power line corona noise occurring at 120 CPS repetition rates. 3. Reduction of local thunderstorm disturbances. 4. And, in general, reduction of any man-made noise which is impulsive in nature. Basically, all the above forms of noise interference are impulsive functions with repetition rates than can extend up to 100 KC in the case of the strokes in a thunderstorm." Those are my sources. Again both descriptions use repetitive pulse rates which are impulsive in nature.??? In order for a NB to function efficiently it is best suited in a wide band signal path that is not restricted by filters. ? Hence a wide IF stage of the receiver before any filtering. As to thunderstorms, since lightning contains many pulses in a single stroke, the NB is suited to minimize those pulses while at the same time, the bulk of the strike energy is affecting the receiver in other means. Namely AGC.? Many receivers suffer grossly from this phenomenon. ? Fortunately Elecraft and Tentec took actions with their designs to minimize this phenomenon based? on the work of Rob Sherwood.? ? And regarding thunderstorms, there is a clear difference in the stroke and content of such for? a "local thunderstorm" as compared to the noise from distant thunderstorms several hundred miles away.?? The distant thunderstorm is affected by propagation and may have several wave fronts with different arrival times where as a local thunderstorm only has a single wave front.?? Hence the waveform is quite different and the means to suppress such will be different. 73 Bob, K4TAX On 6/14/2019 12:24 PM, David Woolley wrote: > The below statement surprised me.?

We place the antennas far enough apart but are in a straight line. The ladder lines are terminated into DXEngineering baluns and with less than ten feet of coax from the balun to the rigs. We have had three rigs on the same band but different modes and no interference and have been doing it this way for years. We gave up on beams, G5RV's, and verticals long ago.

F Y I - {quote} In article by two well-known radio amateurs, ?Tuning Electrically Short Antennas for Field Operation,? appeared in Microwave Journal. Authored by QEX Editor Kai Siwiak, KE4PT, and award-winning researcher Ulrich Rohde, N1UL, the article points out that both Amateur Radio and military applications exist for 20-W battery-powered radios equipped with whip antennas. ?In general, the whip antenna which makes the radio portable is not optimized for signal propagation: A whip antenna has no ground return or proper counterpoise,? the article notes. ?While some users drag a wire of up to 8 meters behind, this is not an ideal solution.? As the article explains, electrically short antennas ? typically 0.1 ? or shorter ? look like a capacitor, with a typical capacitance of 25 pF per meter of length. "At 2 MHz, where the wavelength is 150 meters, an inductor of 84 ?H is required for resonance,? the article says. But just getting a good VSWR is not all there is to it. Rohde stated that loading coil placement in a short vertical antenna is critical, and ?the greater the elevation of the coil, the better the radiation. He said that ?center loading? ? he considers the ?best compromise? to be more on the order of two-thirds? loading ? can dramatically affect both the antenna?s transmitting and receiving performance, as opposed to base loading, as found with popular so-called screwdriver antennas. Radials of some sort also are essential. As the article points out. ?With center loading, both the radiation resistance and integrated surface are larger, which are better for radiation.? Inductors are the lossy components of an antenna tuner, while capacitors ?are infinitely better.? The authors conclude that, for optimal operation, antenna radials should be 0.25 ?, with one sufficient for tuning, and up to four producing a symmetrical azimuth. ?Connecting the HF radio ground to a large metallic object is a good choice,? the article said. Ulrich stated that optimizing an antenna in the manner the article describes will produce ?significantly better? signal reception, although a short antenna will also have a narrower bandwidth. The objective should not be to get a good VSWR but to keep in mind that there?s a difference between resonance and radiation. ?These requirements for optimum antenna performance make HF man-pack radios somewhat complicated and unattractive,? the authors concede.. ?Nonetheless, the well matched and radiating antenna provides the most success, and some of these highly portable radios provide vital communications in disaster areas ? recently in Puerto Rico and South Florida.? http://www.arrl.org/news/tuning-electrically-short-antennas-for-field-operation-is-research-topic{end quote} 73 Bob, K4TAX From kkinderen at gmail.com Sat Jun 15 13:03:39 2019 From: kkinderen at gmail.com (Kevin, N4TT) Date: Sat, 15 Jun 2019 13:03:39 -0400 Subject: [Elecraft] K3s RX & TX EQ...

Keep in mind that Larry hasn't touched / updated LP_Bridge for 3.5 years, plus it's painful to wait for it to start up the virtual eltima IMHO. You just do not get true virtual K3 CAT instances with LP_Bridge that support all the K3 CAT commands etc. Plus with LP_Bridge you can't supply a K3 CAT read only feed direct to hardware at anything faster than 4800 baud, and when you do that, the hardware must be set to Kenwood protocol IMHO, again the hardware won't see the full K3 CAT command set. There is no reason to use Omni-rig with Win4K3Suite. Again, the beauty to true virual K3 CAT feeds. The software and hardware thinks it's connected direct to your K3/S. No more fooling around with another abstraction layer and required support by the hardware you are using. com0com port setup couldn't be easier when you use the com0com graphical setup program. No need to look at the device manager at all. And the port pairs are created at boot time without a laborious wait for Eltima drivers to load like LP-Bridge. The control you get with com0com and Win4K3Suite is much more robust and powerful than LP-Bridge. Hands down... as I said before... LP-Bridge isn't in the same ball park, and I also ran LP-Bridge for years, but I would never go back at this point. However, you can tell I'm a Win4K3Suite fan boy. :) Did you watch my video? https://www.youtube.com/watch?v=zbf7BPfcj4U You are really limiting yourself with LP-Bridge, especially if you use Omni-rig too? No reason for that even with WSJT etc. You just don't need any of that abstraction layer API nonsense with Win4K3Suite. As far as the auto launch question, you should join and post int he Win4K3Suite Groups.io group. Personally, I don't use any auto launch because with Win4K3Suite, once it's started and it does start up fast unlike LP-Bridge (talk about a PITA), you can then just launch the software you want to use for the type of operating you are doing. I start Win4K3Suite and Launch N1MM if I'm going to contest, or DXLap for general operating and WSJT for FT-8, or run them all at the same time. You can see this in the video . By the time LP-Bridge finally starts and creates the virtual ports, you could have everything running twice with Win4K3Suite. As far as the UAC prompt, are you saying that LP-Bridge launches your app without sowing the UAC prompt to run the software as an administrator? Are you starting LP-Bridge as an admin in this case? Try running Win4K3Sute as an admin and launch your apps? Anyway, my two cents... I'm a Win4KSuite fan so its clear I'm very bias at this point, big time and I like the ongoing updates and full support of the K3 full CAT command set. Good luck, I really think you are making it harder than it needs to be where you are trying to use Omni-rig and LP-Bridge and mixing a semi virtual K3 CAT via LP-Bridge and then using UDP broadcasts with Omni-Rig and or a direct Omni-rig connect to a virual port in LP-Bridge? You could do the same thing with Win4K3Sute, but there is no need to introduce Omni-Rig for WSJT, just connect WSJT to a virtual K3 CAT feed from Win4K3Suite or LP-Bridge for that matter. I could go on and on... you are very limited with LP-Bridge... where with Win4K3Suite, you can setup 6 Virtual K3 CAT feeds... using software and or hardware and whatever baud radio you want and you can control if they are read/write polling or not K3 CAT feeds. It's the best $50-$60 software I have bought for my station needs. But then again, LP-Bridge is free. It comes down to good, fast and cheap.... you can only ever have two of those three options and sacrifice the third one. :) Max NG7M -- M.

At our prior home in Auburn CA, I had a 3-phase ~70 KV transmission line on? running across the lower end of the property that connected a series of hydroelectric plants above and below us, and two 3-phase 112 KV transmission lines on towers about 1/4 mile away.? The 70 KV line was essentially quiet.? The 112 KV lines was perhaps S3-4 on 80 and had a fairly high frequency sound ... I guess from the 3-separate phases with peaks occuring at 360 Hz.? The K3 NB was ineffective against it.? With the level set high enough to affect the noise level in the headphones, SSB was highly distorted and CW was chopped up. Here in NV, we are about 1/2 mile from a 500 KV 3-phase transmission line connecting a power plant in Patrick NV to someplace up in OR, probably along the Columbia.? It is fairly quiet, S2-3 on 80, and again seems to be high frequency enough that the K3 NB is ineffective.? I've concluded that, while technically it all is impulsive [arcs on voltage peaks], the peaks must overlap enough and/or are of a high enough frequency that the NB either can't find them or punches too many too big holes in the signal.? It might be more effective on noise from a single phase line, don't know. I rarely hear ignition noise from spark plugs anymore, however the landscape maintenance crew showed up earlier this spring to aerate and de-thatch the grass.? Their aerator gizmo had an old 7 HP engine with strong ignition noise.? The NB took all of it out just fine at very low settings. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 6/14/2019 11:33 AM, Bob McGraw K4TAX wrote: > David et al; > > My statement is almost word for word from the Elecraft K3 manual.?? > And some from work done by Art Collins and company at Collins Radio.? > They prescribed the function of a Noise Blanker as follows: > > "The following operational requirements were kept in mind: > > 1.

You are using SpectraVue?? and I'm not familiar with that, but if it directly supports the K3 CAT feed connection you could simply setup a virtual com0com pair there and SpectraVue would think it was directly connected to the K3.

I've concluded that, while technically it all is impulsive [arcs on voltage peaks], the peaks must overlap enough and/or are of a high enough frequency that the NB either can't find them or punches too many too big holes in the signal.

The noiseblanker in the K3/K3S needs some revision too! TX IMD in the K3S (can?t speak of the K3) can be improved somewhat by increasing the bias however what is possible with a pair of RD100HHF final transistors @ 13,8 VDC is clearly demonstrated by the TS-590 and the new TS-890 by Kenwood (I am not a Kenwood promoter or fan but a clean signal promoter!). Even with increased bias the K3S is not as good............................

Other than that it is easy and inexpensive to add an additional sampler in the output of an amplifier and/or an extra jack on a radio and label it RF SAMPLE OUTPUT/INPUT.

Mostly, the results were about the same as any other rig out there. Kind of OK for ignition noise - using the NB. Of course the NB can screw with the bandwidth of the receiver and allow nearby signals to interfere when they would normally not. Nothing new about this - just like all the others. So far as the NR - all the various (and there are many) settings result in lowered audio output and various levels of "under water" effects. Effectiveness against lightning static is nonexistent. I would be remiss if I did not mention that my IC-7300's NR is very effective against junk when needed and does not introduce "under water" effects. It is also quite effective against lightning static - not 100%, however, I would estimate 80 to 90%. As a result, the 7300 is the go-to rig for noisy weather conditions. I have had no occasion to try the NB, so cannot report on same. As always, the ATT and/or RF GAIN are your friends.

Just before I did this I also noted that when the tuning was not working the ENC A (or B, I didn't note which) was at a constant 4.3 V instead of switching between 5 V and something below 1 V as the tuning knob was turned, and that the overall power supply current dropped either 20 or 40 mA from the normal value.

In the south, it terminates at a large switching/converter station in Sylmar CA north of Los Angeles right next to I-5. It runs north through the Owens Valley [adjacent to and often crossing US 395] and terminates in a switching/converter station near The Dalles, OR. It's primary purpose is to carry plentiful [and cheap] electricity from the Columbia River south to Southern CA. It crosses I-80 near Fernley NV, 20 or so minutes east of us. It is distinctive because it has only two conductors and, except for the dead-ends at direction changes, is generally on very simple pylon towers. I attached a photo from Wikipedia which may or may not come thru. > > Path 65 is very quiet, essentially no change in noise when driving under it. I believe it normally operates at +/-500 KV, but can also be operated against ground at between 700 KV and 1 MV. The earth electrode for the Sylmar converter station is submerged in the Pacific Ocean west of the station.

Mostly, the results were about the same as any other rig out there. Kind of OK for ignition noise - using the NB. Of course the NB can screw with the bandwidth of the receiver and allow nearby signals to interfere when they would normally not. Nothing new about this - just like all the others. So far as the NR - all the various (and there are many) settings result in lowered audio output and various levels of "under water" effects. Effectiveness against lightning static is nonexistent. I would be remiss if I did not mention that my IC-7300's NR is very effective against junk when needed and does not introduce "under water" effects. It is also quite effective against lightning static - not 100%, however, I would estimate 80 to 90%. As a result, the 7300 is the go-to rig for noisy weather conditions. I have had no occasion to try the NB, so cannot report on same. As always, the ATT and/or RF GAIN are your friends. ______________________________________________________________ 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 k9yeq at live.com From Gary at ka1j.com Sun Jun 16 18:48:56 2019 From: Gary at ka1j.com (Gary Smith) Date: Sun, 16 Jun 2019 18:48:56 -0400 Subject: [Elecraft] K3s Sensitive adjustment for FT8 In-Reply-To: <99e36e57-1514-3742-5a3e-aeafe83db883@embarqmail.com> References: <5D0582B7.15088.135F8BFB@Gary.ka1j.com>, <4ed30d25-2e20-21fb-15b2-b6c27ae1b57b@blomand.net>, <99e36e57-1514-3742-5a3e-aeafe83db883@embarqmail.com> Message-ID: <5D06C758.22037.185393E3@Gary.ka1j.com> All excellent advice.

I wonder if there is any information about resistance variations between soldered and crimped terminals. One might think that, with stranded wire, even a good crimp connection might not solidly involve all of the strands, and might additionally deteriorate with time since oxygen could get between the strands. A good solder job should wet the wire through and (additionally) exclude oxygen. This wouldn't be easy to measure, for sure, but these engineers are cleaver people! 73 - George, W3HBM On 6/12/2019 7:55 PM, Don Wilhelm wrote: > [This message came from an external source.

The way to reduce noise on that is to use a narrow filter. NR is really only intended for speech (or in the wider world, music). The key characteristic is that only a small part of the spectrum is important at any one time, but that part is continually changing. NR systems try to work out which parts of the audio spectrum are important and which are not, and construct filters to remove the latter. For CW anything other than the immediate area around the signal is unimportant, and it is not continually changing. The only way you could do better with Morse is by recognizing the signal and regenerating it as a pure keyed tone. The human brain and ear are actually rather good at noise reduction; the problem is that they tire easily. NR attempts to make listening less tiring, not to change a signal from unreadable to readable. -- David Woolley On 16/06/2019 07:39, Dave wrote: > The K3 noise reduction is very poor, I have never found it useful on SSB, > and certainly not on CW.

For what it is worth, the company I worked for prohibited the use of soldered connectors for terminating bonding or power wiring. Especially with regard to bonding, dissipating any lightning strike energy through a soldered connector could cause it to enough to melt the solder. In doing some microwave site upgrades I did pull out a previous generation of bonding wiring that was soldered and some connectors had signs of being heated since installation. In my shack I use crimp connectors and a quality crimping tool with no problems. 73, Nate, N0NB -- "The optimist proclaims that we live in the best of all possible worlds.

Stranded wire that is soldered will also break - right where the end of the solder that wicked up the wire stops. The best is stranded wire with crimped connections made with a proper crimping tool. Done properly, that should result in an air-tight connection that should not oxidize. In order to do that, you must use a crimping tool that is sized for the wire and terminal that you are using. Crimping with just any tool will "not get it". If you do not have the proper crimping tool, soldering is OK, but support the wire for about 2 inches away from the soldered terminal so there is no chance that it can flex. 73, Don W3FPR On 6/16/2019 7:22 PM, Kidder, George wrote: > Interesting data, Don.

They make one or more connections on sacrificial wiring and cross-section them to verify that the crimps are good. Since I cheaped out on a crimper, I did the same to give me some confidence it was done right. A better crimper with the correct sized dies would not require the careful multiple crimps I had to do with this wiring. I've used the Powerwerx crimping tools on many 15, 30, 45 and 75A Powerpoles and not had any issues with them.

I simply adjusted the MIC level (Line) until there was 5-7 ALC bars. The adjustment was quite smooth. Then I went off and did other things and I'm concerned I changed something. Now I have to turn the level way way down on the USB Audio CODEC (-16.4 dB). Then I add another -3 dB using fldigi. Finally, I adjust the Mic to Line = 17. The Mic adjustment isn't smooth. The major change was the addition of the KAT500 and KPA500 (stby) and I'm wondering if either I messed up a setting or maybe created an opportunity for some RF feedback that's affecting the audio. At this point, I don't know how to confirm the signal is clean (especially PSK-31). I've only had one report of a possible problem and a number of reports of "things look good" so I'm calling that a wash. I found nothing in the instructions that told me to drop the level of the USB Audio CODEC and -16.4 dB seems like a big drop. The CODEC is set for 16 bit, 48000 Hz. Am I worrying about nothing? Is your setup with fldigi and DATA A using the K3s's internal sound card similar?

Before our shop started using crimp UHF connectors--RF Industries brand of connectors and crimper--we had a high failure rate of the kludge that is the PL-259 with the UG-174 adapter and blobs of solder (some installed by us, most from elsewhere). In various track machines, trucks, and other railroad equipment I never replaced a properly installed crimp connector. I did replace a number that came from the truck outfitters but those would arrive with a short or without the center pin making contact with the coax center conductor, but that is another story. Yes, annealing of the wire when using solder is a no-go where flexing may occur. 73, Nate, N0NB -- "The optimist proclaims that we live in the best of all possible worlds.

It is actually an audio level control. Do NOT use it to control the power with an Elecraft transceiver - set the audio correctly and use the power knob to control the power. While other amateur transceivers can be made to control the power by varying the audio level, that can be disastrous for Elecraft transceiver Power Control. Read the relevant article on my website www.w3fpr.com for a full explanation. Set the WSJT-X POWER control for 30% to 50% and do the same for the soundcard control in Windows Mixer, then set the LINE IN gain in the K3/S to somewhere near mid-range. By manipulation of those 3 audio level controls, you should be able to achieve the 'magic' indication of 4 bars solid on the ALC meter with the 5th bar flashing - that is the "NO ALC" point for the K3/S, KX3, and KX2 transeivers. The lower 4 bars of the "ALC" meter are there as an aid for setting the audio levels. Set the desired power output with the POWER knob - do NOT vary the audio level. 73, Don W3FPR On 6/17/2019 9:38 AM, Conrad PA5Y wrote: > > Historically there were all kinds of low level artefacts produced by Windows audio algorithms, including the volume control.

I would be very surprised if the Audio codec used in the K3S can reach full scale with the windows mixer at max. I expect that it is limited to -1dB FS. Also I believe that there are further limits imposed i WSJT-X. Therefore there should be no reason for clipping to occur in the CODEC. I expect that there is sufficient range in the mic gain (or whatever it is called) on the K3S. This gives the input signal the maximum SNR which is the socially responsible thing to do. Until I have checked the behaviour of the windows mixer with the CODEC I will not be using it. As I have said previously I don't trust the windows mixer not to degrade the audio due This may well have been resolved but historically was of concern. I think that I will decide what to do when I have made some proper measurements. It's not that I don't believe you, I just like to check things for myself. 73 Conrad PA5Y ________________________________ From: Don Wilhelm Sent: 17 June 2019 17:31 To: Conrad PA5Y; elecraft at mailman.qth.net Subject: Re: [Elecraft] Next Question: DATA A with K3s and Fldigi Conrad, Do check and adjust the Windows soundcard controls to mid-range.

Or is it a K3S? If so did you plug anything into the LINE IN jack on the back - either intentionally or by mistake? That will open the path for the internal soundcard output. Switch to SSB and try transmitting voice - if that works, the K3 is capable of transmitting in DATA A mode, and you have a problem with the audio. While that does not fix it, it will tell you where to look. If this is a K3 with a soundcard not internal to the K3, plug your headphones (or an amplified computer speaker) into the soundcard speaker jack to see if you can hear audio when the software application transmits. 73, Don W3FPR On 6/17/2019 2:39 PM, k2te at juno.com wrote: > I've been using my K3 almost exclusively on WSJT-X FT8 since the mode > came into being.

I believe it?s in good working condition?I haved been able to successfully confirm it transmits, but have yet to have a QSO. It has the following options installed: * KSB2 (1.08b) * KAT2 (1.07) * KIO2 (1.09) * K160M I have purchased the KBT2, since I like the idea of taking this car camping and being able to operate without having to be plugged in. So, I have a few questions: 1. It seems like since it?s a later serial number, so I shouldn?t need to worry about doing any upgrades of the main system. Is this right? 2. I think I also have the latest firmware versions, is this correct? 3. Is there any type of calibration I should do to make sure everything is fine? I don?t really have much in the way of test equipment, such as frequency counters, signal generators, or oscilliscopes. Should I be worrying about this? 4. Should I consider some of the options I don?t have, i.e. the KNB2 or KAF2? 5. I see references to a KDSP2, but that no longer seems to be available, is that right? 6. Any thoughts if getting the KPA100 would be worth it for base station use? Can it be used externally? Is it fine to use it with the internal battery installed? Would it be better to just buy a KXPA-100 in case I ever decide to upgrade to a KX3? 7. I didn?t get the cable for KIO2. I mistakenly purchased the W1SERKT thinking it was what I needed. Would the KUSB the right thing to get? 8. Are there any questions I haven?t asked, but should? Thank you for your patience, and I appreciate your help with my newbie questions. I am super-excited to finally get on the air with HF. 73, Daniel, AG5UT From f.belliveau at comcast.net Mon Jun 17 21:05:22 2019 From: f.belliveau at comcast.net (Francis Belliveau) Date: Mon, 17 Jun 2019 21:05:22 -0400 Subject: [Elecraft] New (second-hand) K2 owner, what now?

As I first rig I might be inclined to check through all the calibrations, but there is no reason to not assume that all is okay for now and see how the rig performs; although filter tuning can be a little personal. So maybe get a copy of spectrogram, hook the rig to your computer and see what the filters look like. Again others can help you with this better than I can. 2. Others are likely to give you advice on firmware, but what you have is likely close enough. I expect that some of mine are older than yours. 4, 5. Both of the KNB2 and KAF2 are useful, but the KNB2 only functions for certain types of noise so it might be lower priority. I could be wrong, but I believe that the chip in the KDSP2 is no longer available so there are no more kits available from Elecraft. 6. I would never think of having the KBT2 and KPA100 installed at the same time. I am not sure if they even can be. My personal choice was to not get a KBT2 and always use an external power source. I have specialized battery setups for what you are thinking of. Although that means carrying two packages, it greatly simplifies things when the battery dies in the field and you want to continue operating. I actually put a KPA100 and KAT100 into an EC2 enclosure that looks nice next to my K2 with KAT2 installed. The EC2 is also no longer sold, but others on the list have talked about alternatives. I suspect that Elecraft may still have some front panels for this setup available. 7. A cable is easy enough to make for yourself, just look up the diagram in the manual so that you get the t]=pinout correct. There is always a lot of discussion regarding USB interfacing. Near as I can tell, it can be problematic so take heed of what others tell you on the list about what to get for a converter.

I have two K2's (s/n 567 and 6911). One QRP, the other with a KPA100. One with the KAF2 and the other with the KDSP2. I highly recommend the KAF2. For me, it has been very effective. With the KDSP2, I have to be retrained on how to use it if I take a lunch break. It works well when I get it set up (that was a major undertaking itself), then if I didn't use it, I'd always have to look everything up. The KAF2 just works. The KPA100 is a good choice and works seamlessly with the K2 (obviously), but if I were considering a KX3 later, I might get the KXPA-100 instead. The KPA100 is only good with the K2. You can put it in a separate case with the KAT100 tuner like KA4FRH and I did, but it still requires the K2 to function. I'd take KA4FRH's advice on calibration. If it seems to work OK, just start using it. Unless something is obviously amiss, don't worry about calibration. Once you've used it for awhile, do the calibration with a little experience behind you. You'll be better equipped to understand what you're doing with the calibration, and know what you want. Good luck with it. The K2 is still a fine rig for HF work. One of mine is ancient, but up to date with mods, so it works as well as the much newer one.

I initially noticed the RTTY window would populate what I sent but still no power out. On a hunch I pushed the XMIT (PTT) button to force the K3 into transmit and sent a message. This time I got power out and heard the RTTY signal in the headphones. I then held the VOX side of the BAND button to activate the VOX, selected a message, and it worked. I opened WSJT-X, picked a frequency, made sure the VOX is on, and it now works. One of the pitfalls of small transceivers with many multi-function buttons that require specific timing to activate the different functions is its easy to screw things up. Apparently I was manually changing bands while operating WSJF-X and held the button too long, thus shutting off VOX. With no warning banner (Do you want to shut off VOX?) or a momentary flashing of the VOX text on the K3 display to notify me, I never noticed it was off. Tnx to those who pitched it with suggestions. Lesson learned for digital modes - make sure VOX is on! 73 de Ed ____________________________________________________________ Sad News For Royal Family track.volutrk.com http://thirdpartyoffers.juno.com/TGL3141/5d084bae5d5114bae2296st03vuc From donwilh at embarqmail.com Mon Jun 17 23:44:21 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 17 Jun 2019 23:44:21 -0400 Subject: [Elecraft] New (second-hand) K2 owner, what now? In-Reply-To: <20190617222508.07B79E131@sarasvati.sattvik.com> References: <20190617222508.07B79E131@sarasvati.sattvik.com> Message-ID: <84800dad-7a7f-b9f5-4e41-79a0fe0e12b9@embarqmail.com> Daniel, All upgrades are included in all K2s after serial number 4300. The firmware should work fine. If you want to check the firmware level, hold any button while powering on and the MCU and KIOC levels will be briefly displayed - the latest is 2.04r/1.09. Since the KSB2 is installed, you need to know how the microphone configuration header is wired. If the prior owner sent a microphone with the K2, then just use that one - or if he told you which microphone was used with it, get a similar microphone and use it. If you have no microphone information, you will have to disassemble the K2 to get to the back of the Front Panel to see how it is wired. Guidance for how to disassemble the K2 is given at https://www.qsl.net/wy3a/Replace_K2_Headphone_Jack.htm. You do not need to replace the headphone jack, but the disassembly of the K2 is the same as in that article. The microphone configuration header wiring for various microphones is shown in the KSB2 manual - download it from Elecraft if you do not have a paper copy. As for other things, you may want to touch up the IF filter alignment, but if it works, I would leave that for later after you become familiar with the K2. You will need to use the internal counter probe to do the IF filter alignment. Elecraft does have a kit of parts for the probe if you did not receive one with the K2 (it may be inside the K2). Yes, the KDSP2 has been discontinued. You will need to construct the special cable shown in the KIO2 manual to have PC to K2 communications. Do NOT plug a standard serial port into the K2 AUX IO connector - it contains internal K2 signal lines as well as 3 RS-232 signals. Using a standard serial cable can cause damage to the K2 and possibly the serial port. 73, Don W3FPR On 6/17/2019 6:25 PM, Daniel Solano G?mez wrote: > Hello, all, > > My name is Daniel, AG5UT, and I recently purchased a second-hand K2 (#5240) as my first HF rig.

Hi Don, Thank you so much for sticking with me on this. K2 #2438 Ver. A with no updates. I had measured 1.48V at bases of Q7 and Q8. (installed.) And as you suggested I removed the PA transistors and now measure 0.63 at base terminals with PAs out. I don't know how you figured that it was PA Q7 and Q8 that were bad Don but you were spot on ! It looks like the PA bias circuit is working but would like your opinion. The table in the manual for Q13 says: E = 0.6V B= 1.3V C= 7.5V (With PA transistors in) My voltages are : E= 0.63 B= 1.2 C= 8.17 (With PA transistors out) Think I should go ahead and put the new PA transistors in leaving the old bias transistors Q11 and 13 in place ?

The usual case is that the base voltage goes much higher and destroys Q11 and Q13, but it seems you are OK. I have seen that condition many times over the years (I have over 1000 repairs under my belt). So when you indicated high base voltage on the PA transistors I knew where it was coming from. The Q13 voltages you measured are within reason.

That's right - this Friday is the First Day of Summer 2019 - and you know what that means! Applications will be accepted for Skeeter Numbers for the 2019 Skeeter Hunt. For those not familar, this event has become one of the Summertime QRP operating staples. It is a four hour QRP Sprint that will be held on Sunday, August 18th. The idea is to get you and your equipment to the Great Outdoors for some QRP fun. A Skeeter Number is not a requirement, but it adds to the fun, so why not get one for yourself, or your group if you want to get out and operate with a bunch of friends? All the details can be found on the Official NJQRP Skeeter Hunt Webpage. Some of these e-mail lists get particular about publishing links - so just Google, Bing, or Go Duck Go "NJQRP Skeeter Hunt" and you'll get the link to take you there. To apply for a Skeeter Hunt Number - send an e-mail, BEGINNING ON FRIDAY, to w2lj at arrl.net and you'll get an e-mail reply with your number. If you don't get an acknowledgement, then I didn't get your e-mail - so try again! 72 de Larry W2LJ Skeeter #13 (in perpetuity) From donwilh at embarqmail.com Wed Jun 19 11:40:40 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Wed, 19 Jun 2019 11:40:40 -0400 Subject: [Elecraft] New (second-hand) K2 owner, what now?

Most of the changes after MCU 2.03 were done to support new changes like support for the K60XV option. The change from 2.04P to 2.04r locked the sidetone source at U8-4 at the request of the support folks who got tired of answering support calls saying "I have lost me K2 sidetone". Great that you got the microphone situation sorted out. Yes, K2FCTR_K2 is the internal frequency counter probe parts.

YES! The K2, for example, is still being sold. The only radios that they have discontinued are ones for which they could no longer buy parts, and the original K3, which was replaced by the K3S. And K3 can be upgraded to a K3S by replacing modules that the owner chooses to upgrade. I upgraded the two K3s I bought in 2008 as kits by replacing the synth boards and the XVTR boards. 73, Jim K9YC From john at kk9a.com Wed Jun 19 22:33:44 2019 From: john at kk9a.com (john at kk9a.com) Date: Thu, 20 Jun 2019 02:33:44 -0000 Subject: [Elecraft] new dead K3s still not fixed Message-ID: <007401d52710$95370a70$bfa51f50$@com> Sorry to hear that you're having problems with a new K3S but I am not sure how you can also purchase a K3 kit, those have not been manufactured in years.

You still have to use the power formula that is in the DL1 manual. I prefer to allow the 'scope to read the full peak RF voltage. Connect the 'scope probe to the side of one resistor which is connected to the BNC jack (one of the leads closest to the BNC), and the 'scope ground probe to one or the resistor leads furthermost away from from the BNC jack. Then use the formula to convert peak voltage to power (for a 50 ohm load) which is V squared then divided by 400. Easy to do quickly with a handy calculator. 73, Don W3FPR On 6/20/2019 9:38 AM, John Oppenheimer wrote: > Using DL1 with Oscilloscope to measure KX3 SSB RMS power: > > https://www.kn5l.net/ssbpower/ > > Question, is this technique correct? > From rmcgraw at blomand.net Thu Jun 20 10:29:15 2019 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Thu, 20 Jun 2019 09:29:15 -0500 Subject: [Elecraft] Measuring SSB RMS Power In-Reply-To: <219ab61e-4b2c-5789-118e-5f3d961eef0c@kn5l.net> References: <219ab61e-4b2c-5789-118e-5f3d961eef0c@kn5l.net> Message-ID: Here is a paper on the topic.

I did specify that the formula was applicable for a 50 ohm load. For other loads, the formula is Vpeak squared divided by 8R. It saves the trouble of converting to RMS and then using the more familiar Vrms squared divided by R. If you wish to derive the formula yourself, you can do that, but represent the RMS voltage as V time sqrt 2 rather then the approximation of 1.414 (or 0.707) which is normally shown. The sqrt will cancel out when it is squared. 73, Don W3FPR On 6/20/2019 10:50 AM, Ken Roberson via Elecraft wrote: > Don , That may be peak to peak voltage squared decided by 400 for a 50 ohm load. > Thanks 73 Ken K5DNL > > On Thursday, June 20, 2019, 9:30:46 AM CDT, Bob McGraw K4TAX wrote: > > Here is a paper on the topic.

Using measured RMS ratios, Vrms=15.3, 15.3/5 = 3V, compared to measured 5.24V. Speech is rather undefined, so not too worried about the discrepancy. My speech with no pauses is ~= Vrms / 3.

The web page is evaluating both expected power to a load and compression gain. Using a little over six second recorded speech. Recording contains fast spoken words, mostly numbers and a few "this is a test" etc, for maximum power over time. Evaluating scope shoot, about 25 words during six second recording. Not even close to pink noise. John KN5L On 6/20/19 11:27 AM, Bob McGraw K4TAX wrote: > To evaluate speech use a pink noise source.

For uncompressed speech, the average value is typically as much as 20 dB below the peak value; compression can reduce that to 10 dB or less.? Highly sophisticated audio processing that has been used by radio broadcasters for at least 40 years reduces that ratio to 6 dB or less.

I anticipate that soon the feds will decide to regulate support of connected IoT devices, requiring update/security support for X number of years after manufacture/sale, if the industry doesn't deal with it first. My advice for the industry is it is much better to steer your own ship than to wait for regulation. In the auto industry, OEMs are required to keep spare parts in inventory for ten years after the last date of manufacture for any particular discontinued model. No word, yet, though, on how long things like an Internet-connected head unit (radio) needs to be kept updated. 73, -- Dave, N8SBE -------- Original Message -------- Subject: Re: [Elecraft] K3s availability From: "Eric Swartz - WA6HHQ, Elecraft" Date: Thu, June 20, 2019 3:12 am To: john at kk9a.com Cc: elecraft at mailman.qth.net Our current plan is to keep the K3S in the product line as long as demand is sufficient to economically produce it.

I'm putting these 2 rigs up for sale now and I'll sell the third one after a K4 ships in early 2020. I will deliver within 100 miles of Houston and $50 can be deducted from the prices if I don't have to ship. If an international shipment is needed, let's talk to see how/if that can be done but I'd prefer CONUS. Here is the blurb I'm sending around: I took some pictures of two rigs I'm selling. If you're looking for a used competition grade K3, I think you would like either of these. Be sure and look at the comments beside most of the pictures which tell what I was trying to communicate with each picture. A full "new" pricing estimate is there for comparison and to detail what is in each rig. The actual selling price is listed below. https://photos.app.goo.gl/PQ9aWkhAcXCmnY5i7 This is S/N 752 (ALREADY SOLD) which has the USB connection (from the KIO3B upgrade) as well as the KSYN3 synthesizer upgrade on main and sub receivers. I'm listing this at $3200 shipped FedEx ground for CONUS. https://photos.app.goo.gl/kbmnKdbEDdJL4hEa7 This is S/N 234 and has the 2 meter module, the K3SYN upgrade (MAIN and SUB), a couple more filters and the general coverage band pass but no USB connection. I'm listing this one at $3400 shipped FedEx ground. My photography skills are not the best but I think someone would get a good idea of the condition of both rigs.

Result was the modulation was pegged at 99.5% all the time, and it sounded that way too ...? zero dynamic range.? Years ago, I looked at KFBK's waveform when the then new Rush Limbaugh was beginning his bloviation career.? It too was nearly constant since Rush could inhale very very quickly and talked very fast. [:-)) Non-classical FM stations [we serviced 4] used peak limiters only since 100% FM modulation is an arbitrary number [75 KHz deviation then].? The one classical music FM station we had used no limiting/compression.? Our TV station used no limiter, NTSC aural deviation then was 25 KHz, however our two network feeds sounded fairly well compressed. I seem to get best audio reports, and recordings a couple of folks have sent me sound best to me when my K3 compression reliably goes to 10 dB with occasional peaks to 15 dB on the bar graph.? Much more than that and there's clearly room noise in pauses and the audio begins to distort. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 6/20/2019 11:15 AM, Jim Brown wrote: > Bob is correct to the extent that Pink Noise approximates the SPECTRUM > of speech, but John's is on target that speech is not continuous, but > highly variable in amplitude.

In-Reply-To: <1550080605704-0.post@n2.nabble.com> References: <1550080605704-0.post@n2.nabble.com> Message-ID: Hi Mike, I am working on taking my station completely off the grid. Have three 12 volt 100 watt panels and looking for radio compatible charge controllers. I have a 1200 amp-hr station battery I made from 6 1200 amp-hr cells that I plan to charge with just these panels. The station battery also runs a 45 quart Whynter AC/DC fridge just incase our AC grid goes away since we are out in rural Yavapai County with just a single phase power line coming in to the area. I like the ideas in the other emails on quiet charge controllers. I would add that our house here in central Arizona has forty 250 watt panels on the roof with two Sunny Boy SMA-5000TL-US inverters each with the 1500 watt off-grid feature. I specified to EV Solar here in AZ ( out of business now unfortunately) that the installation should be RF quiet. The EV Solar owner said that then I needed these particular inverters as they were the quietest he had installed. With my K3 and my 160m OCF inv V and 40/30/20 yagi 200 ft away up the hill behind our house I can not tell the different between the inverters up and running and when I open the solar inverter DC and AC breakers. Or for that matter when I switch one of the inverters to off-grid and feed that 1500 watts to my station ( when garage/shack built the electricians wired that circuit in to the shack with the other inverter off-grid circuit going to the kitchen). I charge my station battery with a 9AM to 3PM timer now so that I have a good backup. Just run my station on house AC other that when we have a power outage. Our 40 panels produce more w-hrs over a year than we use but we use the local power company as a "battery" and only get paid whole sale price for the excess power we generate so have to pay for electricity 3 months out of the year. Of course connect charges of about $15 each month even if we do not pull power. Long term goal is restoring this house to its original off grid condition. I have another south facing 15 ft x 30 ft roof area without panels but also will need to add batteries for the house and upgrade the inverters. One other ham friend who did not pick these SunnyBoy inverters, rather has panels with individual grid tied inverters had to turn them off for noise free operation. Another friend with one of these SunnyBoy inverters has zero HF noise. 73, tom w7sua On 2/13/2019 10:56 AM, mjpilgrim wrote: > I've employed a small solar power system to supply my ham shack which > includes K3-100/P3, two PCs with flat screen monitors, and 20" flat screen > TV.

Many of the programmable chargers have a discharge function ( check the current limit in this mode and then derate it, otherwise you may fry your charger). Then when you charge set the voltage max to 15V. There is still a lot of margin, reading through the manual I found a reference to 16V as the max voltage rating. Certainly this approach decreases the Ah capacity of your battery since you are only partially charging it but repurposing is a cost effective. 73?s Andy K3CAQ > On Jun 23, 2019, at 3:05 AM, Victor Rosenthal 4X6GP wrote: > > If you decide to nerd out, all you need is a series diode. > > 73, > Victor, 4X6GP > Rehovot, Israel > Formerly K2VCO > CWops no. 5 > http://www.qsl.net/k2vco/ >> On 23/06/2019 10:15, Howard Orridge via Elecraft wrote: >> I have a bunch of Lipos from a different and less venerable hobby which can comfortably work between 13.2v and 15.4v, but have avoided use with the KX3 because of the 9v to 15v range.

I've done a little bit more troubleshooting and it looks like a hardware problem on the radio. When I plug the P3 interconnect into the P3 CAT stops responding. With just the USB connection present it behaves. The instant I plug in the P3 (the connector next to the USB plug on the K3s), I lose CAT control. I'm leaving it unplugged at the moment, but it's not ideal. - pjd -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Christian Friess Sent: Sunday, June 23, 2019 4:34 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3s USB failure?

This is interesting. I never disconnected the P3, and it sat on my main operating desk all weekend. It was just the K3s that went outside (sunny/dry and less than 10 feet from my shack desk). I disconnected all the cables from the back of the K3s inside, brought it out, connected it to my spare PSU, plugged it into the computer and everything came up perfectly and I was ready to go in under a minute. This afternoon I brought it in, reconnected all the cables and that's when I noticed the problem. I didn't touch either of the DE9 plugs on the P3, and they're tightened down securely on that panadapter end. But something is definitely amiss from the other end; either the RJ-45 plug on that cable, or the connector on the radio itself.

They can be damaged if you accidentally insert something besides the RJ-45 plug. You may be able to straighten them, but if that object was metal and the K3S was powered on at the time there is probably going to be other damage. I would remove the cable from the P3, then resigner it just to make sure. Also, to make sure - if the RJ-45 is _not_ plugged into the K3S, does the USB communications work properly? I think that is what you are indicating. If so, the connector and the cable are suspect. 73! Jack, W6FB > On Jun 23, 2019, at 4:34 PM, Peter Dougherty wrote: > > Hmm. This is interesting.

I didn't touch either of the DE9 plugs on the P3, and they're tightened down securely on that panadapter end. But something is definitely amiss from the other end; either the RJ-45 plug on that cable, or the connector on the radio itself. Again, if I wiggle the connector, power the radio down, and restart Commander or N1MM (or the K3 Util), it MAY work.

VSWR threshold can now be set to 1.60 for all bands (but is reported as 1.59 due to rounding issues mentioned in the help documentation). New firmware is available here - https://elecraft.com/pages/firmware-software Thanks Dick. 73, Andy, k3wyc ________________________________ The KAT500 utility provides the means to set a VSWR threshold for Key Interrupt either by individual band, or the same value for all bands. Selecting ALL, entering 1.50 in the Amplifier Key Interrupt box, selecting Apply, results in 1.50 being set for all bands as expected. After the operation Apply is dim. Leaving the Config menu and returning to it still shows 1.50 selected for all bands. If All is reselected, 1.60 entered, and Apply selected then Apply does no go dim but the individual bands, and ALL, each show 1.60. Then select OK and Operate. Then return to Configuration, edit Configuration, VSWR Thresholds. With ALL selected Amplifier Key Interrupt is blank. Inspecting the value for each band shows 160 = 1.59 and all other bands 1.50. The entered value of 1.60 was not applied. This anomaly seems repeatable in that 1.50 can be entered, 1.55 can be entered, 1.80 can be entered, but 1.60 and 1.56 cannot be. The sign that that data entry has failed is that Apply does not go dim. Is this a known problem with KAT500 utility 1.16.7.25?

Message-ID: I suspect I may have an issue with the Line In port of my K3, as my ability to TX in any digital mode has gone away. Setup: 1. Using a Tascam US-122 MKII outboard sound card. 2. MIC SEL is set to Line In on the K3. 3. Digital software, e.g., WinWarbler and WSJT, have the Tascam selected for TX and RX. 4. Mode selection for FT8 is set to Data, for RTTY is set to AFSK 45 bps. 5. Levels are the same as when this system worked ? K3 Mic level is set around 43-44. Symptoms: 1. When I try to TX on FT8 from within WSJT, the K3 red TX light comes on and over my headphones I can hear a steady tuning tone, but I have no power out, not one bar. 2. During TX I do hear ?behind? the tones a brief low level buzzy/crackly sound that recurs every second or so. 3. I get the same results as above when trying to TX in WSJT, though I hear tones typical of a transmission vs. a steady tone. 4. I get the same results as above when I switch to RTTY and TX within WinWarbler; RYRYRY, but no power out. 5. The Tascam and WSJT work fine together to decode FT8 signals. T-shooting Steps to Date: 1. Uninstalled, rebooted and reinstalled all Tascam software and current drivers. Same results. 2. Tried the Line Out from the internal PC soundcard to the Line In on the K3. This also involved using a different cable from that connecting the Tascam to the K3. Reconfigured the digital software to use the internal sound card for TX. Same results as described above (including the noise). 3. Verified the K3 does TX (at least on CW). I suspect the board with the Line In port may have gone bad, but not sure if that?s the issue. If so, is there anything further worth checking or should I just replace the board?

With digital modes, you should have enough audio to drive it to 4 bars with the 5th bar flashing. See the article on my website www.w3fpr.com. Can you transmit in SSB mode? If so, the K3 audio is fine and you can focus on the Line In or the soundcard output for the problem source. 73, Don W3FPR On 6/24/2019 9:29 AM, Paula Uscian wrote: > I suspect I may have an issue with the Line In port of my K3, as my ability to TX in any digital mode has gone away. > > Setup: > 1.

Check to see if the level is set properly, i.e. 4 bars with the fifth flickering. If not try setting the line-in gain to that level.

This was the K4's first outdoor shake-down. The stakes were high, since the K4 has to pick up where the K3S/P3 leave off, fulfilling a dual role as both a high-end desktop and field/portable station. Observations: - the light weight (~10 pounds) made it easy to transport and set up - there was virtually no mutual interference between the K4 and a very active 40 meter SSB station using an antenna about 40' away - thanks to the low noise at this location we were able to hear many weak signals clustered together, and found signal clarity to be excellent - the LCD was clearly visible, without color washout, despite a full assault by bright sunlight bleeding through our translucent white tent cloth (some other radios at the same location had displays that were almost impossible to see) - the ATU did was able to tune a narrow-banded 20 meter yagi on other bands, when necessary, including 15, 10, and 6 meters - the radio ran from a very small Li-Ion battery (KXBT2, ~2.5 AH) for quite awhile, proving it works at 11 V, which is important for stations running from a somewhat depleted car battery or other emergency supply - operators were very complimentary of the internal speaker, though I'm partial to stereo audio and was using a pair of 8", 4 ohm (passive) external speakers most of the time We had a bit of fun late in the afternoon on Saturday when we switched from the Yagi to an AX1, Elecraft's 4 foot 20 meter whip. This may seem frivolous, but it's an important test because it shows that the radio's shielding is working well. It should handle an end-fed wire with a balun right at the antenna jack. Here are some comments we received afterward from KJ6K: "It was a real thrill to play with the K4 while making making CW contacts with it during Field Day. It's an amazing technical and usability design achievement. The user interface for many modern radios is so complex that an operator may need to refer to the manual frequently to figure out how to access a desired function, and never be able to do so quickly. The display on the K4 is gorgeous, and the use of touch, along with physical controls, provides a very intuitive and efficient user interface. "My own interests in ham radio have always been mostly in the science and engineering, so my operating is mostly casual, with HF CW my favorite mode. The architecture of the K4 is really exciting; the performance and endless possibilities for features and connectivity is really cool." Thanks, John!

I set them up this way to keep the mechanical clacking noise down and liked it so much that I changed my other paddle for my shack radio to the same adjustment. HOWEVER? on the KX2, after just a few minutes the paddles get loose again and start clacking again. There is a separate set-screw (that was loose) that I thought might make tighten onto the adjustment screw and keep it from backing out. I?ve tightened them, but they don?t seem to affect the adjustment screw?s ability to get loose. And, I don?t see these screws on the exploded view I got with the KX2 or on the PDF on their website.

Message-ID: Paula, Your problem may be as simple as bad cable connections between the K3 line in and your soundcard. I had the same problem that recurred several times and drove me nuts. I was getting audio out of the soundcard when going to transmit. (I also the problem with AFSK-A RTTY.) I finally found the problem by pressing on the cable at the line in port on the K3 while in TX mode and saw power out/ALC action return. Replacing the cable solved the problem. 73 de Ed ____________________________________________________________ Warning from God Discovered in Human DNA healthrevelations.net http://thirdpartyoffers.juno.com/TGL3141/5d1116ce27c1a16ce0819st03vuc From marklgoldberg at gmail.com Mon Jun 24 14:44:30 2019 From: marklgoldberg at gmail.com (Mark Goldberg) Date: Mon, 24 Jun 2019 11:44:30 -0700 Subject: [Elecraft] K4 Field Day report In-Reply-To: <04B9D3D4-6EED-44D4-BE94-CE3E55BBBBDD@elecraft.com> References: <04B9D3D4-6EED-44D4-BE94-CE3E55BBBBDD@elecraft.com> Message-ID: I'd be interested to hear how it does in the presence of close in strong signals, especially SSB.

Four cells will keep the voltage between 12 and 14.4 V from 10% to 100% state of charge and most of the time the voltage is between 13 and 13.5 V. I use small ones (3 AH )for backpack portable operation, 20 AH for fixed portable and my RV has 400 Ah to run the rig forever! The KX3 stays at the max 15W almost all of the time. No fuss, just works, and they keep their charge for months. Small ones start at about $50.

Saturday, I got to FD, 2.5 hours from home, to a sister Clubs operation, they invited me to come down and work some cw. When I arrived, they were running an American rig (not Elecraft) on CW station, I operated it for a few hours. I asked if they minded if I ran my own radio, which was no problem. I'm sure glad I brought my pelican case, with my trusty "old" k3 and p3, no "s", no updates, no narrow filters, no nuttin! It was like going from an HW-7 to a K2... Sorry, but I'm ruined. Have Elecraft, will travel. I won't be moving to a k4... No need. I'm happy. 73 all Dean K2WW On Mon, Jun 24, 2019, 13:32 Nr4c wrote: > Hopefully there will be a lot of them in users hands by then (MINE)!! > > Thanks for the update. > > Sent from my iPhone > ...nr4c. bill > > > > On Jun 24, 2019, at 1:11 PM, Wayne Burdick wrote: > > > > George (KJ6VU), John (KJ6K) and I operated a basic K4 for several hours > as the 20 meter CW station at the Bay-Net Field Day site east of San Jose. > This was the K4's first outdoor shake-down.

I was thinking Joe's recommendation below was my last option. But then a strange thing happened. In doing some last checks before exploratory surgery on the K3's IO board, I decided to unplug the Phones jack of my Radiosport headset from the front of the rig and plug it into the phones jack on the TASCAM to confirm that I was hearing tones on TX. I did hear the tones (as I had before with the phones plugged into the K3 and listening via the K3 monitor). But after I plugged the Radiosport phone plug back into the K3, voila -- I have a reading on the ALC meter. Of perhaps greater significance, I verified operation is now fine by completing a Q on FT8. I also now have TX for RTTY as well. I'd like to think I'm home free due to clean living ;-), but fear I may have a dreaded intermittent issue. Time will tell. Many tnx agn to all who responded, your comments were most helpful. For completeness of this thread, I've included responses to some of the recommendations and questions below. 73 Paula k9ir 1, VOX shouldn't be needed with FT8 using WSJT as it communicates with the K3 via CAT commands. FYI no difference with or without VOX. I have used VOX for RTTY AFSK in the past, but got disabused of that sin when I had some issues with WinWarbler that were resolved by running Commander.2. It is difficult for me to test a different cable as the TASCAM Line out consists of 2 RCA jacks. I happen to have a cable with 2 RCA plugs at one end and a 3.5mm plug at the other end, but I don't have another one to try (note to self -- get another cable just in case). However, I did run a totally different 3.5mm to 3.5mm cable from the Line Out (Green) port on the PC to the Line In port on the K3 and got the same failure (AFTER reconfiguring the software to look to the internal sound card for TX). Yes, it is possible I have 2 bad sound cards and 2 bad cables, but I'm playing the odds for next steps ;-).3. I have been using the meter selection that shows ALC during these tests.4. I do hear tones -- a steady tone when I click the Tune button and modulating tones when I click the TX button, in WSJT -- in my headset, so I think the TASCAM Line Out is working.I just see no bars on the ALC display. I also checked to make sure recent Windows 10 updates didn't alter my Privacy settings for the microphone; those permissions remain the same as when the system was working.

What I found was all 3 showed from 80 to 90 watts output on 160 meters and on 6 meters I saw 75 to 90 watts. All other bands showed typically from 105 to 110 watts. However, one of the K3S showed exactly 100 watts on all bands except for the lower power on 160 and 6 meters. I did check one of the K3S before doing the current Firmware update and saw no difference before and after the up date on 160 and 6 meter power output.

I have an annoying problem with the KX2 Paddle. The contacts continue to get loose. I have them adjusted so that there is very little play.

I was thinking Joe's recommendation below was my last option.

I did hear the tones (as I had before with the phones plugged into the K3 and listening via the K3 monitor).

For completeness of this thread, I've included responses to some of the recommendations and questions below. > 73 Paula k9ir > 1, VOX shouldn't be needed with FT8 using WSJT as it communicates with the K3 via CAT commands. FYI no difference with or without VOX. I have used VOX for RTTY AFSK in the past, but got disabused of that sin when I had some issues with WinWarbler that were resolved by running Commander.2. It is difficult for me to test a different cable as the TASCAM Line out consists of 2 RCA jacks. I happen to have a cable with 2 RCA plugs at one end and a 3.5mm plug at the other end, but I don't have another one to try (note to self -- get another cable just in case). However, I did run a totally different 3.5mm to 3.5mm cable from the Line Out (Green) port on the PC to the Line In port on the K3 and got the same failure (AFTER reconfiguring the software to look to the internal sound card for TX). Yes, it is possible I have 2 bad sound cards and 2 bad cables, but I'm playing the odds for next steps ;-).3. I have been using the meter selection that shows ALC during these tests.4. I do hear > tones -- a steady tone when I click the Tune button and modulating tones when I click the TX button, in WSJT -- in my headset, so I think the TASCAM Line Out is working.I just see no bars on the ALC display. > I also checked to make sure recent Windows 10 updates didn't alter my Privacy settings for the microphone; those permissions remain the same as when the system was working. > On Monday, June 24, 2019, 08:40:09 AM CDT, Joe Subich, W4TV wrote: > > > Check L4 and L5 on the KIO3 Audio Input board.?

Each of K3S were updated to the current Firmware and each had the 5 and 50 watt calibrations run. What I found was all 3 showed from 80 to 90 watts output on 160 meters and on 6 meters I saw 75 to 90 watts. All other bands showed typically 105 to 110 watts. However, one of the K3S showed exactly 100 watts on all bands except for the lower power on 160 and 6 meters. I did check one of the K3S before doing the current Firmware update and saw no difference before and after the up date on 160 and 6 meter power output. Does anyone have any idea as to why I am seeing the lower outputs on 160 and 6 meters.

The tripod attaches to a camera using a smaller plastic piece that screws onto the camera (or the antenna) and snaps onto the platform. There?s just enough clearance for the BNC connector.

The watt hours (Wh) rating is marked on newer lithium ion batteries and is explained in #3 below. External chargers are also considered to be a battery. With airline approval, devices can contain larger lithium ion batteries (101-160 watt hours per battery), but spares of this size are limited to two batteries in carry-on baggage only. This size covers the largest aftermarket extended-life laptop batteries and most lithium ion batteries for professional-grade audio/visual equipment." Last month, I took a KX3 to Sint Maarten (PJ7). My battery was a Bioenno 6AH, equivalent to 72 watt hours. It worked like a charm! You need to check with your airline, as some -- but not all -- airlines will allow you to take a battery as large as 160Wh. The larger Bioenno's (9AH and up) are over 100 Wh Bioenno has listings on their website of recommended batteries for most commonly available rigs, based on your duty cycle. 73, Eric W3DQ -------------- Jim Brown wrote: Yes.

K3/10 gets 10w on 14-MHz and 8w on 50-MHz. KXPA gives 100w on 14-MHz and 80w on 50-MHz using a Bird43 meter with a Bird dummy load. Into an antenna power is dependent on match (as one would expect). The KXPA only needs about 5.6w drive for full output on 14-MHz but requires full 8w drive on 50-MHz.

The loading coil arrangement was a little awkward, I thought. By nicer to have a roller inductor for quicker adjustment. A single radial wire was used and 2:1 balun to get 1.2 SWR. Stepped 1:1/2:1/4:1 balun was nice. Buddy tripod and fabric carrying case had me thinking this would be handy for portable operation with my RV at CG's.

I was forced to run QRP (which isn?t an issue as I am primarily a QRP contester anyway) as anything over 5 watts caused the rig to overheat to the point of automatically reducing power to 5 watts. Had WSJT, JT Alerts and even N1MM all cooperating and auto logging so all I had to do was stop reading the newspaper and occasionally glance over to the computer to see if I had worked anybody since the last time I clicked on a callsign. Then I started to notice my setup wasn?t completing a lot of calls which I had initiated. I started to pay more attention to the screen and discovered that it appeared to me that my signal was getting swamped out by QRO (100 watts or more on FD) signals which I couldn?t readily detect. At a suggestion from the FT8 FB group switched on the hold-my-transmit-frequency button. On CW my rates aren?t much different from QRP to 100 watts as I?m only 2 S-units down and aggressive operating skills can compensate for a lot of differences in power and I can deal with QRM I can hear and see. Not so on FT-8. I am rebuilding my contest station and only have the end-fed and an HF-2 vertical up right now and know that better results on QRP are largely antenna and location dependent (oh to live on a saltwater marsh).

With that in mind, try: 1) Check the front panel to see if any keys are stuck. 2) Disconnect the serial port then power up the radio. 3) If the above don?t work, reset the parameters. This is described on page 72 of the K3S Owner?s Manual, Rev A1. And if all that fails, try giving tech support a call. 73!

So I set up the voltage reading a the VFO B window and noticed that the voltage had dropped down to 12.1V when I keyed down, but the power supply said 13.7V at key down. So I shortened the power cable, by 32" and now it is 24" long. Now I see 13.1V at VFO B window and 100 watt on 160 meters and 105 watts on 6 meters. I increased the power supply voltage to 14V and now I see 13.3V at VFO B window, on key down and now 105 watts out on 160 and 110 out on 6 meters. So to make a long story short, the K3S will put out over 100 watts on 160 and 6 meters if your power supply voltage is at 13.8 volts and you keep the power cord short. The additional 32" of power cord dropped the voltage by 1 volt on key down.

Key down voltage is 13.4 volts on the VFO B display at maximum power out. Elecraft offered to upgrade my PA chain for $100, but I'm not concerned about ~1dB and is within spec for 6m anyway. Glad that diode is in there.?

With a solid 13.8 volt power supply voltage, you should see no lower than 12.7 volts (there is a diode drop inside the K3). If lower, check the connections in the power cable for tightness. The K3 power cable should run direct from the power supply.? Rigrunner and other DC power distribution boxes can be reason for excessive voltage drop. You can increase the power supply voltage up to above 14 volts to help - do not exceed 15 volts. 73, Don W3FPR On 6/24/2019 6:51 PM, EVERETT SHARP via Elecraft wrote: > I have three K3S and over the week-end I connected each of them to my Bird watt meter, with a Dummy load.

I've seen a demonstration whereby using 2 antennas and a computer device, the unit will be able (to some degree?) determine signal direction. Does Elecraft have plans to develop K4D software with such capabilities or sanction 3rd party development of such? Will there be other software / firmware development to come with the K4D beyond that of a dual receiver K3/s? Lastly, beyond control and perhaps IF output, will the K4 receiver(s) be able to interface with external 'computers?' (No, I'm not sure what I mean by that!)

I half suspect that some of the sunspot predictions we've heard are made by ex stock market quants and commodities chartists; it wouldn't surprise me if they started referring to inverse head and shoulders, cup and handle patterns, sunspot breakouts, etc. On the bright side (pun), if there is a long spell of inactivity in the solar magnetic field it will allow more cosmic rays to hit the earth's ionosphere which will help light it up a bit. Not sure if that is much of a silver lining for HF radio but it is something. 73, Drew AF2Z On 06/24/19 21:55, kevinr wrote: > I found this paper and thought some of you would be interested.

I asked him to install wsjt-x before coming onsite. I then configured wsjtx-x for him. It took less than 30s to do that. Wsjt-x has an ARRL field day mode with an entry field to add in your exchange. Click click click and you?re done. It is very simple and wsjtx handles the cadence and the FD exchange like a boss. Wsjtx seemed to handle most situations and made operating a joy. It also gave me an opportunity to teach other hams and visitors how to operate FT8 using wsjt-x because of its ease. I used also wsjtx for my digital station as paired with a KX3. I used the KX3 with solar power to gain a 100 point bonus. The KX3 was a champ. Handled the voltage variances from the panel by automatically reducing power from 10w down to 5w when the voltage wasn't quite enough for 10w.

It sounds like he was not depending on any of the home station infrastructure e.g. antennas, so I think that he was in class 1B, one or two person portable or even perhaps 1Bb if he was battery QRP. YMMV. But see also: 6.9. Batteries may be charged while in use. Except for Class D stations, the batteries must be charged from a power source other than commercial power mains. To claim the power multiplier of five, the batteries must be charged from something other than a motor driven generator or commercial mains. 73 Bill AE6JV On 6/25/19 at 11:20 AM, jim at audiosystemsgroup.com (Jim Brown) wrote: >On 6/25/2019 6:37 AM, Peter West wrote: >>When our club?s plans for FD fell through at the last minute I set up 1B with my trusty >KX-2 with a Bioenno battery and two internal KX2 battery pacs on my back porch. > >FWIW, that puts you in 1E, not 1B. ------------------------------------------------------------------------------------- Bill Frantz | Government is not reason, it is not eloquence, it is force; like 408-356-8506 | a fire, a troublesome servant and a fearful master.

However, I'm still a little concerned about what I see for ALC. The video below (no audio) shows the ALC meter responding first to a "TUNE" command from fldigi. This sounds like a pure tone in the headphones but the ALC meter responds oddly, almost like it is pulsating. I expected ALC to pretty much be steady. Next in the video is just clicking T/R in fldigi with no typing. It sounds as expected in the headphones (a trilling sound). The ALC response looks better but I can still see the pulsations in there. I expected to see 4 bars solid and the 5th flashing. https://photos.app.goo.gl/4AaLaVu1r8UDv5LT9 Am I reading too much into this? Is this how your K3s responds? I'm using the K3s sound card. Level in Windows is -14.7 dB. Level in fldigi is -12.7 dB.

Thankfully, there was a very simple solution. Although I had disconnected the CW paddle, as well as a number of other cables, I couldn't crane my head around enough to notice that I'd left a 1/4"-to-1/8" adapter in the paddle jack on the back panel, which apparently had become partially unseated. When that was fixed, the problem went away. 73, Frank K6FOD On 6/25/19 6:51 AM, Jack Brindle wrote: > This sounds like the K3S is getting commands fed to it when perhaps it shouldn?t be.

Convenient access across one?s backyard to their home station facilities is not in keeping with the spirit of Class A or C lass B portable operations. Such convenient backyard operations on property of home stations remain either Class D (commercial power) or Class E (emergency power), even if home antenna structures are not used. If the station will be a ?good hike? away from a hom e station ( eg, at the rear of a several acre lot, or perhaps operating from a farmers field down the road) - clearly away from home conveniences (away from home utilities, or home restrooms/bedrooms, or even eating facilities/refrigerator/kitchen) - then Class A (3 or more pers ons portable) or Class B (1 or 2 person portable) is appropriate.

First thing to be determined is -- does it have an IF output? If so, the 2nd thing to determine is -- What is the IF output frequency? The P3 can be tuned to use an IF output between 455kHz and 21MHz. If there is no IF output, then you would have to add one. The Icom forums would be your best resource for the base way to add one. 73, Don W3FPR On 6/25/2019 5:59 PM, Jim Dodds wrote: > Has anyone added a P3 Panadapter to an ICOM CI-9100 transceiver?

The combination of my K3's great performance with super smooth CW keying and the P3 pan adapter all rolled into one. It's great to see everything in a single package with a large display. I am really excited to see the additional enhancements like CW, PSK, RTTY decoding on the same screen eventually. The APF for peaking CW signals is amazing. The front panel is very comfortable to use and having all these features in a single radio with this performance and yet not too heavy to take to the field is a real treat. * * * 73, Wayne N6KR From hamdan at ix.netcom.com Tue Jun 25 19:51:48 2019 From: hamdan at ix.netcom.com (Bernie and Cheryl) Date: Tue, 25 Jun 2019 17:51:48 -0600 Subject: [Elecraft] Firmware Updates Message-ID: I got my K3s (#10323) back in October, 2015, and got my KPA 500 (#2664) a few months later (I have the full K line including the KAT 500).

After that, look in the K3 Utility Help file for the Firmware Release Notes. You will find information on the firmware updates between what you are now using and the latest. If any are of interest to you, then update your K3S to the latest. Simply click "Send All Firmware to the K3" and wait for it to complete (do not interrupt the process). It will take only 3 to 5 minutes. I would encourage you to update the firmware as it is available. It is much different than Windows Updates, and much less disruptive. You have to initiate the update rather than having Microsoft, etc. deciding it "is good for you" and automatically installing. In most all cases, the firmware updates are painless and take nothing away from your prior operation, but only add new features that may enhance your operating experience. Should the very worst happen and your computer has a glitch during the update process, recovery is easy. Just follow the instructions in the K3 Utility Help File for "Force a Firmware Download", and all will be well after that. That problem rarely happens - computer power glitch, user interruption and other similar situations. If it should occur for you, recovery is easy - just follow the directions. I have only encountered it once in the 10 years I have had my K3 when I did "fumble fingers" to interrupt the total download. 73, Don W3FPR On 6/25/2019 7:51 PM, Bernie and Cheryl wrote: > I got my K3s (#10323) back in October, 2015, and got my KPA 500 (#2664) > a few months later (I have the full K line including the KAT 500). > > When I built them, I promptly updated the firmware, and haven't done it > since.?

One antenna was an 80M inverted V, the other was a Butternut vertical mounted over a salt water tidal canal.? I generally found when the signal faded, thus more errors, on one antenna the signal was stronger on the other.?? The system switched antennas during the receive cycle. ?? I also incorporated a power control system which looked at each packet acknowledgement and would reduce TX power a small amount.? After a number N of missed acknowledgements it would increase power in small amounts.??? It was nice to have a radio which I could control power by applying a few volts to the ALC input. The aluminum Butternut vertical over tidal salt water presented one issue, which was the SWR changed multiple times per day as the tide cycle rise and fall.? The SWR change wasn't a lot but clearly noticeable a 3' to 5' tide change.? In effect the ground moved up and down, regardless of the amount of copper buried in the canal bottom.?? I guess that stuff is still there as we moved away and left it in the canal.?? Oh, the Butternut is now located in my shop,? clean and ready to install again.??

The antenna for the day (end-fed 40-20-10) was set up on the Saturday and the only AC power was used to power the logging computer although I could get around that too if I was so inclined. I even drove in a new ground rod. Sorry if I wasn?t clear enough. Several requests about how I got WSJT-X, JT-Alerts, and N1MM working with the KX-2 I?ve answered directly but essentially whenever I have software issues I just reinstall everything and follow online videos or posts about what to switch on and what to switch off. Generally this works fine sooner or later. (Can?t wait to try setting up RTTY on my Flex 6600!) BTW I?ve decided that the best way to contest using a weak-signal mode like FT-8 is to run at least a 100 watts into a big antenna at the proper height. A kilowatt would ensure success. 73 Peter - VE3HG From turnbull at net1.ie Wed Jun 26 14:01:01 2019 From: turnbull at net1.ie (Doug Turnbull) Date: Wed, 26 Jun 2019 18:01:01 -0000 Subject: [Elecraft] K4 Ergonomics etc In-Reply-To: References: Message-ID: <4F1DDECF0DC54098B50065FD31322F83@DougTPC> Dear OMs and YLs, I had a chance to see the new K4 at Friedrichshafen. It was like visiting flowers with bees swarming to have a go. I am impressed and have a few points perhaps not mentioned previously. 1) Ergonomics: a) The Main tuning know is raised and has clustered directly around it certain LEDS and Switches of particular use in tuning. LEDS are TX, Delta Freq, SUB (RX), and DIV for diversity. Having "Delta Freq" directly adjacent to the tuning know may help me remember to stay off a DX frequency. Switches are Freq Ent, Scan, Lock A/B and Sub/Div. Positioning these switches right at the main tuning know seems to me an improvement over the K3/S. b) Having the Spectrum display directly in front and on the radio itself yet also giving a good size for the spectrum display is also to my liking. c) Because the spectrum display is built in, the radio is not as wide as a K3 and P3 combination. The HDMI port still allows me to have a 24 inch monitor for the frequency display so the slightly smaller display will not cause me difficulties. d) A built in P3 should reduce the number of external cables. e) The tactile feel of the switches has been improved. 2) Economy, Many accessories of the past are built in. a) No need for a DVK CW, voice recorder card as this function is built in. b) No need for a more stable oscillator as this too is built in. c) No need for a wide band filter to allow general coverage because if you switch out the superhet front end, you already have a general coverage RX. Eric confirmed that the Superhet front end can be bypassed. d) No need for a 4 kHz filter for FT8 as you can just switch out the superhet front end. FT8 is normally not a mode used in contesting so should be pretty robust without the superhet front end. e) No separate P3 f) No need for an accessory board in the K3 to enable an external monitor. 3) Ease of installing updates for diversity and also superhet front end; I understand that it will no longer be necessary to unplug the front control panel in order to install these options. This was always a bit of a worrying moment for me though I have assembled three K3 radios and removed the front panels on a number of occasions for updates such as installing the DVK. I am an old goat with shaky enough hands and deteriorating eyesight. I should go through the specs to compare total weights of a fully equipped K3 and P3 combination to the fully equipped K4. This data is probably not yet available. How will the power consumptions compare? It will be interesting to see the full specifications and Sherwood test results. No matter, my plans are to purchase in the next twelve months. I like the Elecraft philosophy of keeping the radio relatively small, light and most importantly allowing for future enhancement. Agreed you will work anything with the K3 that you can work with the K4. Most likely the 7300 will work 99.9% of what the K3 works but a VW Beetle will do what a Porsche does but just maybe not with the same style. 73 Doug EI2CN PS Sadly there will be no Fred Cady, KE7X book this time to further inform.

I have the P3 with transmit sensor and SVGA additions. A few years ago I had it serviced and everything is working nicely. By now I am comfortable with operation and I have figured out how to tune things up for maximum performance. I even have a Rose Kopp K3 bag embroidered with my call sign. The biggest criticism I have heard of the K3 has to do with the quality of the audio. The K3 rig is a bit shrill and harsh compared to some other rigs I have heard. I have a nice pair of Sounds Sweet speakers (alas no longer made) that solves that issue for me. I have looked at the K4 materials on line and I understand the multiple advances this rig will offer. If I went for it I would go for the full HD version. I want the maximum possible advantage in a contest situation. But to spend 5 grand plus I would need to see some improvement in performance to justify the substantial additional expense. That includes receiver performance as well as advances in DSP and noise reductio I am going to hold off on ordering until I see some test reports and evaluations. I will probably order next year after the kit option becomes available.

Got a Par 40-20-10 end-fed up about 40? in a north-south orientation only to find band conditions here were pretty bad here in the north with QRN, QSB and faint signals at best. So switched to FT-8. I was forced to run QRP (which isn?t an issue as I am primarily a QRP contester anyway) as anything over 5 watts caused the rig to overheat to the point of automatically reducing power to 5 watts. Had WSJT, JT Alerts and even N1MM all cooperating and auto logging so all I had to do was stop reading the newspaper and occasionally glance over to the computer to see if I had worked anybody since the last time I clicked on a callsign. Then I started to notice my setup wasn?t completing a lot of calls which I had initiated. I started to pay more attention to the screen and discovered that it appeared to me that my signal was getting swamped out by QRO (100 watts or more on FD) signals which I couldn?t readily detect. At a suggestion from the FT8 FB group switched on the hold-my-transmit-frequency button. On CW my rates aren?t much different from QRP to 100 watts as I?m only 2 S-units down and aggressive operating skills can compensate for a lot of differences in power and I can deal with QRM I can hear and see. Not so on FT-8. I am rebuilding my contest station and only have the end-fed and an HF-2 vertical up right now and know that better results on QRP are largely antenna and location dependent (oh to live on a saltwater marsh). Running FT8 with the KX-2 on FD was an education and I?ve got to do some thinking about how to improve my chances if I decide to try this again. All in all great fun with some learning but can?t wait for more future propagation.

I use the eme sw MAP-65 to process the output of both Rx and it resolves the angle of polarization and maxes signal strength in alignment with the actual angle of polarity. There is another sw called Linrad that can do that for two signals (written in Linux). http://www.sm5bsz.com/linuxdsp/linrad.htm MAP-65 is authored by Joe Taylor - K1JT who also created FT8 and FT4.

Polarization describes the geometric orientation of the antenna and the resulting EM field. Polarity is the positive or negative going sense of voltage or current in a circuit (what for decades we mistakenly called "in phase/out of phase).? Polarity has two values, positive or reverse. We change the polarity by turning the wires over in a circuit. Phase is a continuously valued function and is measured in degrees or radians. The phase relationship between two signals has meaning only for sine waves of the same frequency. The phase relationship between antennas is a function of the distance between them, the frequency of each signal they transmit or receive. Further, this phase relationship is different for every angle from which a signal arrives or to which it is transmitted. The phase relationship also includes the electrical lengths of the transmission lines involved, and, of course, the difference in phase increases in proportion to the frequency of the signal. There's a tutorial discussion of these concepts in http://k9yc.com/VE3DO.pdf in the context of how the DX Engineering NCC-1 and NCC-2 work to steer the directivity of two spaced antennas. The same laws of physics are at play in this discussion. 73, Jim K9YC On 6/26/2019 9:20 PM, Edward R Cole wrote: > I feed signals from two antenna that are orthogonally polarized (one > is horz and other is Vert polarity, both pointed in the same direction > and essentially in-phase). > I use the eme sw MAP-65 to process the output of both Rx and it > resolves the angle of polarization and maxes signal strength in > alignment with the actual angle of polarity.

I'm pretty certain he meant "polarization".? I know he has done some work (and written about it) using cross polarized antennas (orthogonal and spaced a bit apart fore and aft relative to the arriving signal) to measure both the degree and direction of ellipsoid arriving signals, and I remember that he took great pains to account for differences in the feedline delays. When he's simply looking for the tilt angle and not the handedness of the ellipse, as he states below the two orthogonal antennas are in the same plane ... but if the arriving signal is circularly polarized the phase will indeed appear to be different between the two antennas.? If the arriving signal isn't particularly circular but simply has a polarization tilt, the phase difference would be small and the differences in amplitude would indicate the angle of tilt. Be sure to correct me if I'm wrong here, Ed.? I'm doing my best to visualize this stuff. I think Ed is telling me in in his post below the name of some software that allows him to compare the two signals, and presumably that is the case for both amplitude which he is using to get the tilt angle, and for phase, which I want to use to get arrival angle using two horizontal antennas one above the other or azimuth using two vertical antennas spaced laterally.? It will be interesting to see if that does the job. As I once posted in the past, I have previously fed the audio from both K3 receivers while tuned to the same frequency in diversity mode ... with the signals coming from two different antennas, one above the other by a known distance ... into the sound card of my computer running a simple dual trace audio oscilloscope application.? By triggering on one of the signals while looking at the delay in the other signal I could get an approximate indication of the change in arrival angle over time, so I know the concept is valid.? To get a clean reading I used some 40m AM broadcast carriers during periods when there was no modulation, such as between programs.? The angle changed 10 to 15 degrees in fractions of a second, and if had been able to accurately know the delay difference between the two feedlines I would have been able to calculate the absolute arrival angles instead of just the changes. To be honest, the software necessary to do all of this should be fairly straightforward.? I'm just not knowledgeable enough to code it myself.? From my perspective it should also be possible to do it inside the K3, K3s, or K4, but if that doesn't happen (and it appears that it won't) I'll try to figure out how to do it with a separate application. As you say, all of this can be accomplished at RF as is done with the DX Engineering boxes ... but it can be done more simply at audio via software (at least for receive) since phase is preserved upon down converting. 73, Dave?

Although the time zone geographic definitions are set by international treaty, a shift to year-round "Advanced Time" without altering the boundaries of the Time Zone only takes a resolution of Congress to permit the deviation from the Uniform Time Act of 1946. Had the states decided to forego the time shift and remain on "Non-Advanced Time" year-round - such as Arizona and Hawaii do - it does not require anything more than a state ordinance.

It does not totally nor correctly apply to Elecraft radios as power management is handled by a totally different means.?? And those means and methods suggested in this paper are not applicable to Elecraft radios for power control.?? From experience in set-up and operating different radios and different interfaces, I do believe that the WSJT-X operating panel which shows the right slider labeled PWR is very misleading and should be changed to some other description i.e. TX AUD. While many radios use the control of audio level to adjust power output, this is somewhat misleading as there are control areas available such as SPKR level in Windows, and Line Gain for the radios or perhaps an external sound card device.?? Again, the use of the acronym MIC is always a frighting term,? in as much as many systems produce a transmit audio level that will overdrive the microphone pre-amplifier input.? Once this occurs, reducing MIC gain will not relieve the distorted audio as it occurs pre level control in the circuit.?? Frankly, one should not connect the sound card to a microphone input without proper and correct means of attenuating the signal before it is connected to the microphone input.?? In addition, this will always preserve the transmit Signal-to-Noise ratio. As to "compression" I take that to mean Speech Processing, which should ALWAYS be off or set to a zero value.?? Likewise for EQ, again always set to OFF or FLAT? for transmit and receive purposes as well. As a mater of practice, there are three or perhaps four distinct places that audio levels can be controlled in the transmit path. First is SPKR level which is the audio level out of the computer. Second is the WSJT-X PWR slider, and third is the Line Gain within the radio.? A fourth, if used, would be an external interface such as a Signalink or Soundblaster.?? If any of these points end up near minimum value or near maximum value, I strongly suggest further investigation as to why and remedial steps taken to more "normalize" the control values at all points in the system. Some radios do have "meter" indicators which relate to ALC levels while others simply prove a visual means usually the illumination of a LED.? In all cases, the indicators should be observed, and the radio operated accordingly with NO indicated ALC action occurring.??? Again, regarding Elecraft radios, the first 4 bars on the "ALC Scale" are audio level and NOT ALC action.? The onset of actual ALC occurs at the 5th bar and higher. 73 Bob, K4TAX On 6/28/2019 9:18 AM, Andy Durbin wrote: > Does anyone know of any rig that uses "compression" rather than linear gain control to implement ALC? > > ref - https://www.dropbox.com/s/f4uaop5tqwzaweu/FT8Noise6.docx?dl=1 > > 73, > Andy, k3wyc > ______________________________________________________________ > 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 rmcgraw at blomand.net > From ve3bwp at gmail.com Fri Jun 28 11:48:13 2019 From: ve3bwp at gmail.com (=?utf-8?Q?Brian_=E2=80=9CVE3BWP=E2=80=9D_Pietrzyk?=) Date: Fri, 28 Jun 2019 11:48:13 -0400 Subject: [Elecraft] Sending KX3 to Elecraft for repair from Canada Message-ID: <3FAC731D-974E-41F0-8D44-50F570546FBA@gmail.com> I?m hoping to hear from any Canadian HAMs who have successfully sent their radio (KX3 in my case) to Elecraft USA for repair and got it back with the least amount of brokerage hassles.

Your question will encourage that! I found that UPS's Customs Forms generator produced a Sales Invoice even though I asked it to produce a Temporary Export for Repair. So I crossed out the Sales part and wrote in pen that this was a repair and will be returned. My parcel has been received and neither Elecraft or UPS have informed me of any charges. Though an email from US Border Control when I've just received in response to my question talks about Bonds. I may have been lucky that the HSS Code for radio transceivers is duty free as the bond is about duty which does not apply (at least from friendly countries according to the US Border Control web site) An impression I got is that nobody can predict, or will stand by a prediction, about what Customs will do. UK Customs helpline advised me to state "FOR REPAIR" on the outgoing forms and "BRITISH GOODS RETURNED AFTER REPAIR" on the return (or something like that). In the end someone at UPS I think it was said that putting "Export Reason: Repair" on their form should do it. Elecraft note that they have experience of how to handle the return, and I've included a copy of the radio's sales receipt as suggested so if needed I can prove that UK VAT has been paid already when it comes to re-importing it. So I've been successful. I can say that what I did was quite simple in the end, but I only _think_ I understand the procedure. - Richard On Fri, 28 Jun 2019 at 16:49, Brian ?VE3BWP?

Paul, The usual cause of destructive failures like these from lightning is interconnection of equipment powered from AC outlets having different green wires, or whose green wires are not bonded together, or equipment whose chassis are not all bonded together. This situation is made worse the use of shunt-mode suppressors on AC branch circuits. Many years ago, colleagues working in pro audio design experienced destructive failures of the ethernet circuitry of networked computers from lightning. No antennas involved -- these were engineering offices. The solution for these failures was (and is) the use of series-mode suppressors on the AC line branch circuits. Surge-X is the manufacturer of these products that has concentrated on the pro audio and video market. There are (were) two other mfrs I'm aware of -- Brick Wall I remember, but not the other. 73, Jim K9YC From donwilh at embarqmail.com Fri Jun 28 14:35:04 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Fri, 28 Jun 2019 14:35:04 -0400 Subject: [Elecraft] Sending KX3 to Elecraft for repair from Canada In-Reply-To: <3FAC731D-974E-41F0-8D44-50F570546FBA@gmail.com> References: <3FAC731D-974E-41F0-8D44-50F570546FBA@gmail.com> Message-ID: Brian, Use the postal system.

Likewise, for digital modes, audio drive level should never be used to set output power, but rather so that levels are within the best operating range of both computer and radio audio stages. 73, Jim K9YC From bill at wjschmidt.com Fri Jun 28 14:51:13 2019 From: bill at wjschmidt.com (Dr. William J.

Many of the digital application instructions tell you to set for NO ALC as a *maximum* audio level, set the power control for the maximum desired and then reduce the audio level to reduce the power - I think that is why the slider in WSJTX is labeled POWER when it is really an audio level control. The above method works fine for many transceivers, but NOT for Elecraft which measures the actual power output, compares it with the set power and adjusts the RF drive accordingly. This is a fully closed loop system. As far as I know, Elecraft is the only amateur transceiver using that type of system. With Elecraft transceivers (except for the K2), adjust the audio drive level to produce 4 bars solid on the ALC meter with the 5th bar flashing (this is the NO ALC point. Then leave it that way and adjust the desired power with the power knob. Doing otherwise will result in low power at the start and power hunting as the transmission goes on. 73, Don W3FPR On 6/28/2019 2:38 PM, Brian Denley wrote: > I have always thought that ALC is not appropriate for power control.

Depending on your soundcard output, you may still need an attenuator. Strive for each audio control in the computer and application to be at 30 to 50%, and then if you have too much audio with the KX3 MIC Gain set near its mid-point, then you will have to add an attenuator. One note on the KX3 - if you drive the audio with too large a signal, the mic amplifier will shut down and the MIC GAIN will not work anywhere in its range. 73, Don W3FPR On 6/28/2019 3:01 PM, Richard Corfield wrote: > That's interesting thanks.

Just below clip, the second harmonic was -30 dB; at half that voltage out, it was -40 dB. To put this in perspective, Thinkpads are better than average laptops. This is the basis of advice I first published around that time to first set the output level of sound cards 6-10 dB below full output and then set input level in the rig. There are app notes on my website that describe three different ways to do this, depending on your available tools, one being our ears! The "ears" method is this.? Plug headphones into the computer output jack, have the computer generate the tone(s) your going to transmit, and increase the output level until you hear the tone(s) sound a bit rougher, then back off the output of the computer until the tone(s) sound half as loud. This works because our ear/brain perceives a change in loudness of 6-10 dB as "half (or twice) as loud." 73, Jim K9YC On 6/28/2019 2:29 PM, Joe Subich, W4TV wrote: > > Among other issues, this article is incorrect when calling for the > "Device" (Master) volume level in Windows to be set to 100%.

Were you operating the KX3 on batteries when you found that oscillation? If so, the internal resistance of the batteries would be the cause of the oscillation. For the computer connection, just use standard stereo audio cables - no need to match impedance - just set the audio level correctly. For amplified speakers, I recommend West Mountain Radio COMspkr mainly because they are shielded and do not howl with the transmit RF. 73, Don W3FPR On 6/29/2019 1:01 PM, Dennis via Elecraft wrote: > I searched the KX3 manual and could not find a specification for the headset/speaker output jack.

I have always been a bit unclear on what the Elecraft ALC/power was really doing. You mention low power then then hunting, and the notion of a set power level, measuring, and adjusting gain. That makes me think that there is an initial gain that is computed/calibrated somehow, that if right will not result in an adjustment right away. Presumably that's a known relationship between an audio input of an appropriate power and the desired RF level. Is that a fair characterization, or if not, could you explain how it's wrong? I am guessing also that there is some kind of silence detection or max gain, as keying the mic without speaking doesn't lead to ramping up to full-power transmitted noise. I could see the power loop having a narrow range, enough to account for how much variance there should be, but not 40 dB worth. I have seen repeatedly about "4 bars solid and 5th flashing" as the right place, and the "no ALC" point. Is there really an ALC circuit, that reduces gain in the audio stage when a higher input level is measured? Does this have a sufficiently long decay time constant so that an FT8 or PSK signal would get adjusted acceptably and still have a low-distortion signal? Or is there still a transfer slope where the output ends up too high? Overall, this seems like having two coupled control loops instead of one, and I'm guessing that the point is to have different time constants in each one, or to get the levels right at two points in the circuit instead of one, by having audio gain and RF gain separately controlled. Is that accurate? Separately, I wonder about issues with different levels of different audio frequencies resulting in a transmitted signal which while not necessarily distorted is off plan and therefore less well decoded (assuming there isn't adaptive equalization in the decoder after pilot tones, and I don't have the impression there is). Does this end up being an issue in practice? I would hope that with the relatively close spacing within an FT8 signal that this is likely to be not a problem. tnx es 73 de n1dam From davidhweiss at gmail.com Sat Jun 29 13:52:43 2019 From: davidhweiss at gmail.com (Dave Weiss) Date: Sat, 29 Jun 2019 13:52:43 -0400 Subject: [Elecraft] Diversity Receive setup??

After a band change or a change in the POWER knob, the power control loop is reset. The response time is quick enough that you do not notice it in normal operation, although it does take a dot or two in CW or a couple of syllables in voice to obtain enough RF output to be properly measured by the wattmeter and fed back to the MCU. In the case of digital modes, if the audio is not sufficient, the measured power will be lower than what is requested by the power knob and the radio will begin to ramp up power - but if one or more of the RF stages has reached its limit, there will not be enough power, and the RF output level will come up quite slowly or not at all - so the radio continually "hunts" for the power the power requested, but never makes it. So keep the audio up to that specified for data (4 bars solid, 5th flashing) or voice modes (5 to 7 bars) and all will be well. 73, Don W3FPR On 6/29/2019 1:35 PM, Greg Troxel wrote: > I have always been a bit unclear on what the Elecraft ALC/power was > really doing. > > You mention low power then then hunting, and the notion of a set power > level, measuring, and adjusting gain.

Changing from 12M or 17M to 15M causes a fainter "pop". A much more attenuated "pop" happens when changing from 14M to 10M, and also from 10M back to 14m. Also, on 15M, when changing from VFO B to VFO A I hear a loud "pop", but it does not happen going from A to B. The fainter "pops" might have always been there, but the ones on 15M are loud enough to cause the clip light on my DSP to turn red. I wonder if it has something to do with diodes across relays, or the relays themselves. Any more ideas?

Odd as it sounds, I'm looking for an "amplifier" to switch in to bump 10-25 fold to 2-5W as the T1 likes 2-5W for initial tune cycle and 0.5W thereafter. The T1 has latching relays so it seems I *could* tune with a KX2 and then swap in the WSPRlite - so that's the backup plan.
