Re: [Elecraft] P3
Hi Jim, I’ve discovered that it’s easier to see a very weak signal on the waterfall than in the amplitude plot. Setting the SVGA screen for 25% spectrum and 75% waterfall gives lots of space to see dim traces. You may have to adjust the threshold a bit. 73, Brian, K0DTJ > On Dec 17, 2023, at 12:13, Fred Jensen wrote: > > Can't speak to the K3s, but the K3 required a modification to the 1st IF [8 > MHz] gain for my P3 to show weaker signals.

Re: [Elecraft] K3 - Erratic receive
According to the schematics, those two double pots on the front panel are merely voltage dividers. They provide 0 to 5v signals to the front panel MCU which controls the function, eg: AF_GAIN. It’s possible the pot has developed a dropout right at the point where you usually set the AF level. Maybe turning the pot stop to stop a half dozen times will improve it?? Worth a try. 73, Brian, K0DTJ > On Nov 29, 2023, at 12:12, Pete Smith N4ZR wrote: > > My 2400-serial number K3 has begun to have a sporadic receive problem, which > has gotten much worse recently.

Re: [Elecraft] Elecraft CW Net Report
Kevin, You were good on 20 meters with some deep QSB but OK copy. Then we got whacked by the sun pretty hard between nets and the story changed on 40 meters. I could hear you at first but your signal was below the noise peaks so your CW was getting chopped up and nearly uncopyable.

Re: [Elecraft] Power spike early K3
I had a similar problem and traced it to voltage sag under load at the K3. The power supply was good under load but there was too much loss in the stock cable which was wired directly to the PS. I replaced it with a heavier, shorter cable. I found that I had to run the TX gain calibration twice in a row to get it right. It’s been fine since.

Re: [Elecraft] Keying the K3s
I’d like clarification on this also. I don’t run an amp but I’ve run my K3 for years at 5 watts for QRP events without issue. My TUN PWR is set to 7 watts to keep my remote tuner and LPA happy. The manual states that to manually initiate a TX GAIN calibration to set TUN PWR to exactly 5 (or 50) watts and hold the TUNE button. I can imagine that accidentally doing so into an antenna rather than a 50 Ohm dummy load could really mess up the TX GAIN calibration.

[Elecraft] Elecraft SSB Nets
Richard, The Sunday Elecraft Nets all use relays, so if you cannot hear the NC you can get picked up by a relay. The 20M net on 14.3035 at 1800Z this week will be K1NW in Rhode Island. The 40M net on 7.280 at 1900Z is usually WM6P, Steve, in northern Georgia. The 80M net is run by Dave, N8SBE, in Michigan at 9 pm EST (note not UTC) on 3.775. I hope you can join us today!

[Elecraft] Elecraft 20M SSB Net Results, Dec. 11, 2022
Erik WB9JNZ was off flying his R/C planes but we carried on. Band conditions were good with John in CA hearing Peter in New Zealand on his doublet. Several new K4s checked in. We speculated on how long this net has been meeting - Phil NS7P found paper logs of the net dating back to 2009. Thanks to relays: John N6JW, Phil NS7P, Steve WM6P, and Carl K8NU.

Re: [Elecraft] K3S Noise Reduction
There was a very good description of the K3 NR written by Lyle, the DSP designer for Elecraft. It may be on their website. Basically, as I understand it, the NR is designed to work against random noise. Noise that has a correlated component, like line noise, it doesn’t address as well. I’ve found that, properly adjusted, it works very well on CW but using it on SSB created unacceptable “mush” on the audio. Hopefully the spectral subtraction NR when available on the K4 will be much better. 73, Brian, K0DTJ > On Nov 6, 2022, at 17:34, Richard wrote: > > Is there ANY way to make the NR feature work worth a damn?

Re: [Elecraft] Recommendation for Microphone for K3s?
Like you I’m 99% CW OP but for years I’ve used inexpensive (~$20) computer headsets with my K3. Light weight and don’t clamp your head. Comfortable to wear for hours. They’re a bit hard to find these days because most are Bluetooth. The K3 TXEQ can make it sound good. 73, Brian, K0DTJ > On Nov 1, 2022, at 14:13, Bernie and Cheryl wrote: > > Dear Folks: > > Although I'm primarily a CW op, and dabble in FT8 (sadly, sometimes there's > no one on anywhere else except for FT8), I'm thinking about expanding my SSB > presence on the bands.

Re: [Elecraft] KX3 Question on S-Meter Calibration
I thought I understood this but appears that I had it wrong. According to the SMTR calibration procedure, it is set with the PRE on and ATTN off. Calibration sets a 50uV signal to S9 and a 1uV to S2-S3. See this in the Calibration Procedures section of the manual (p51 in my 2009 version). I’ve been using the SMTR ABS mode ever since I discovered it.

Re: [Elecraft] [K3] Strange Selective Hearing in My K3
Sounds like a thermal problem, possibly with the 8v regulator. I have a problem with my K3 (S# 4K range). If the rig is cold ~60 F the 8v apparently goes out of regulation evidenced by the display illumination dimming on key down. The rig works normally otherwise. The problem goes away once the FP Temp warms a little - I wrote the number down somewhere but can’t find it now.

Re: [Elecraft] AX-1 -- with and without counterpoise
Ha! I did the same thing last night only with slightly parameters: 0.2 inch diameter 4 ft. rod (average diameter of AX1?) with the base 5 ft above average ground. Counterpoise (#18 wire) drops 4 ft from the feed point then trails out 9 ft to about 2 inches above ground. The base loading coil was 11.3 uH with a 6.7 ohm series resistor for a Q of 150. Not surprisingly, the gain plot showed best gain in the direction of the counterpoise: -0.37 dBi at 30 degrees elevation. Gain in the opposite direction was -4 dBi. So if you are in a QSO with someone, you should be walking away from them. :-) SWR at 14.050 MHz resonance was calculated at 3:1. Interesting exercise! 72, Brian, K0DTJ On 9/26/2022 12:15, David Gilbert wrote: I modeled something similar to an AX1 with EZNEC last night. I used a base loaded 4' length of 1/2 inch diameter tubing for the whip, a roughly 10 uH coil with a Q of 200 (25 turns, 1.5" diameter, 3" length), and a 13 foot #14 counterpoise wire. It was oriented vertically with the bottom end of the counterpoise wire being 2 feet above "typical" ground. The frequency was about 14.1 MHz. It looked surprisingly decent for both SWR and field pattern ... only about -2 dBi ... although of course we should be suspect of the accuracy for a model that severe. The calculated field strength without the counterpoise wire was about -10 dBi, but that's clearly unrealistic because the SWR was 700 (no exaggeration). In practice I'm sure that other things (human body, coax shield if used, proximity of the rigs case to ground, etc) have a moderating effect, and they all likely introduce additional loss. I don't think there is any way that EZNEC can accurately model something like that, and we also have the issue of how much loss there might be in the tuner trying to match such a difficult load. Thus the urge to do a real world test, although I'm coming to believe that no matter how hard I try, it probably isn't possible to control proximity effects well enough for the case without the counterpoise wire to get a truly definitive comparison. That SWR of 700 in the model was because the feedpoint had a capacitive reactance of 35,000 ohms (!!). It is certainly debatable whether that figure is accurate, but there can be no doubt that it is very high. A ballpark comparison is therefore about the best I expect whenever I find myself able to do the test. 73, Dave AB7E On 9/26/2022 4:05 AM, Gerry leary wrote: I have used my AX2 both ways, and I have never found it to be advantageous to use that antenna without a counterpoise.

Re: [Elecraft] Elecraft CW Net Report
Thanks for checking me in Kevin. It was my first time on a CW net and I was nervous, relying on Text Decode on my K4D, etc. Conditions were as weird as they were on the 20M SSB net at 1800 - one way strong - reverse weak. I could barely copy you. On 40M I listened around for 10 minutes but the TN QSO party dominated and I heard nothing from you. I hope to continue checking in! Thanks for running the net.

Re: [Elecraft] switchbox KX3 to signalink/mike+headphones
Pretty simple home brew project, I would think. Four stereo jacks, a DPDT switch, a small box and a capacitor should do it. The capacitor is to block the mic bias from going to the Signalink. You would still likely have to adjust levels whenever switching. Would take some study to get all the connections right. 73, Brian, K0DTJ > On Jul 23, 2022, at 17:29, Andrew (A.J.)

Re: [Elecraft] Reset KX2 to factory settings.
Hopefully you saved the configuration using the KX2 Utility. If so, just reload it. In the manual, there is a table containing the menu descriptions and their default options. Easy to go through and a good place to learn what they do. EEINIT is described on page 56 of the manual. Basically the top line says DON’T DO IT. If you do, you must have a configuration file to reload all the calibration data and defaults. Good luck!

Re: [Elecraft] Elecraft K1 VFO reading

[Elecraft] XV50 Rev B - Questions
Hello - I recently purchased an XV50 to use with my K2. While setting it up for a K2 with no K60XV per the manual, I noticed that there is no JP9, where I am supposed to short pins 1-2. On closer inspection, my XV50 has a rev B board and it appears these pins don't exist. The assembly manual I found online is for a Rev E board and owners manual is for Rev F1. I'm assuming all the other jumper settings from the Rev E manual are correct for my Rev B XV50, but I thought I'd ask here for clarification before I damage my XV50, since it's almost irreplaceable now days. Also a Christmas wish would be to purchase a K60XV if anyone has one laying around that they'd be willing to sell.

Re: [Elecraft] Problem with my KXPD2
The KXPD2 comes with two small hex-keys. The larger is fits the screws that adjust the spacing. The smaller one is for the pivot screws to adjust the setting of the pivot bearings. It sounds like your pivots are possibly too tight or have dust in them. I would try loosening the pivot screws slightly to see if that frees them up. The pivots should be set so the paddles move freely but with no up/down looseness. Then set the spacing to taste.

Re: [Elecraft] KX2 temperature
I believe the trip temp. is 60c. The rate you get there, of course, depends a lot on power setting, mode and ambient temperature.

[Elecraft] K2 fan etc
I keep an eye for discarded PC computers on garbage and recycling days here, mostly to take out the 12 vdc fans from the power supply. I have those in abundance now, more than I need. But I run them on 9 vdc with no trouble (wall warts and such) or from the 12 vdc I might be using for a rig. I use those fans on top of my Drake tube gear with the open perforated cabinets and so on.

Re: [Elecraft] [ELECRAFT] Are there any "bad radios"?
Great thoughts on radio purchases Geoff. I have owned all the major brands - kenwood, icom, yaesu, ten tec - at least 2x each - and got both great contacts and valuable learning time on every one. I now own a K3, KPA500, P3 and KAT500, which could be my last radio and that would be fine with me. If I can resist the pull of a K4!

Re: [Elecraft] KBPF3A switching frequencies and performance
This thread also got my curiosity up. Several years ago I upgraded my K3 #41xx with the KBPF3 including the 'A' mod of the capacitor on the RF board. I never really checked it out except for the 630 meter coverage and transmit capability - both were as advertised. Using a wideband noise generator (QRP Guys K7QO Noise Bridge) I tuned from about 500 kHz up to 30 Mhz and was able to identify the filter switch-over points (most of them anyway). I measured the received noise level using the P3 dBm scale. At none of the switch points was the noise level more than about 5 dB different from one side to the other. By continuously tuning and watching the display, it was apparent that the differences were mainly due to roll off of one filter segment or the other. The gain was uniformly consistent across each of the ham bands but sometimes rolled off at the KBPF3 switch points. The area between 7.41 MHz and 8.4 MHz is kind of no-man's land due to the first IF being there. At the IF frequency the gain was down >50 dB. 73, Brian, K0DTJ On 4/20/2021 08:57, w4sc wrote: A little back ground,, The effort started as a result of my using WWV at 15.00 MHz for calibrating the reference oscillator.

Re: [Elecraft] Inventorying a K3/P3
Dave, There have also been numerous component adds/mods over the years. Three that I did a couple years ago are 1. Increase the 12vdc accessory power from 500 ma to 1 A. Evidence is a 1A sticker on the rear of the K3. 2. Add a capacitor to the KPA3 to eliminate fan noise pickup evident after the new synthesizers are installed. 3. Addition of a capacitor to the KBPF3 general coverage BPFs to extend coverage down to the 630 meter band. I’m sure there are others. See the mod instructions available on the Elecraft site if you go sleuthing inside the box. These are a bit inconsequential but add value to the K3. Have you thought about asking Elecraft for the work orders for the K3’s S/N? Good luck and thank you for helping out the family.

Re: [Elecraft] Copying CW and Pitch
Iworked for years on 405 line TV transmitters. I had a notch of at least 40dB at 10.125khz.

Re: [Elecraft] KX2 Starts Off with Low Output on 10M
Nate, A couple more questions: Does the KX2 do the same thing on CW? Did Elecraft say anything about doing a TX gain calibration? This can be done with the KX2 utility although I haven’t done it on mine, just on my K3. It sets the per-band gain coefficients Be sure to save the current CONFIG file so you can restore it if needed. You will need a good dummy load an a stable power source. The procedure is on p. 38 of the Rev A5 Manual.

Re: [Elecraft] KX2 Starts Off with Low Output on 10M
The KX2 uses a control loop to set power. Make sure you have sufficient audio drive to energize the loop. Using the ALC display set the MIC GAIN so you have 5-7 bars on voice peaks, per the manual. What MIC are you using? Have you tried the internal MIC?

[Elecraft] WTB: KAT-100 Autotuner for K2
Hello - Happy customer and my first post here on the reflector. I have had a K2/10 for about two years and enjoy using it as my primary rig for both CW and SSB. I have other QRP rigs and I really need a 100W transceiver, so I recently made the decision to upgrade my K2 with the internal KPA-100. I would also like to get the matching KAT100, but unfortunately the ATU is no longer available from Elecraft. Does anyone have a KAT100 sitting around that they are no longer using and would be willing to part with for the right price? My email can be found on QRZ.

Re: [Elecraft] Efficiency of MFJ remotely-tuned loop antennas
I got a MFJ 10-30m loop at a SK sale. The original owner had never got it to work. The rotor vanes had fallen apart. The fixed vanes were welded to the loop. After re-assembly it worked well, but was difficult to tune as I couldn't hear the buzzer for finding the tune point, it was too high in audio frequency for my old ears, cured by adding a capacitor to the circuit.

[Elecraft] using K2 as external VFO for vintage tube rig
Hi, I wonder if anyone can enlighten me on this... A few days ago I came across a posting where someone said they were using their 'PLL VFO' aka their K2 as the substitute VFO (in absence of the xmtr having one) or as a crystal substitute. OK, how does he do that? Is he just running key-down at a low power of continuously keyed signal OR essentially keying the K2 at low power as a keyed-VFO into his vintage rig? Anyone want to venture a guess? I know I used to be able to use an old Hallicrafters tube VFO (Master Oscillator) as a continuous running VFO (irritating since the signal could be heard in the receiver if you did not turn off the final tube power when in receive) or it could be run as a keyed VFO, where the keying keyed the cathode of the final tube. So, similar kind of thing if attempted with K2? Anyone else done this? I have a few decent QRP rigs I could conceivably use as VFO / xtal sub / master oscillator ... whatever term to drive my older tube rigs (and avoid the mess of DDS). Since I don't do 80m all that much, a 40m signal from a K2 or some other QRP rig would suffice to drive 40m, 20m and 15m as doubling and tripling of signal (IIRC). tnx Brian VE3VAW __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 arch...@mail-archive.com

[Elecraft] K4 IF signal 'OUT' for external application useage
Looking at the recent (though long from complete) K4 guide, I don't see an IF OUT per se as I have in the accessory board in my K3 (or in fact the output I/Q from the KX3 I can run directly into my sound card on the computer). Does the XVTR IF OUT suffice for this? The reason I ask is that eventually my LP-PAN is going to die - hopefully not soon but I have been using it for quite some time now. I use the IF out from the K3 into the LP-PAN and then into NaP3. Now I do realize there is a panadapter on the K4 - obviously - but I DO enjoy (in fact pretty much need) the large computer display for the pana/spectrum display and DO use the NaP3 software controls for K3 functions on my keyboard and mouse for tuning and such. The display on the K4 is not the same thing I don't think. Even with some keyboard/mouse controls native to the K4 (?) the display size is a deterent to me as it exists. Apologies to the company. I assume maybe there MIGHT be a video card OUT re. the K4 panadapter at some time, but that is a maybe.. and more money. I won't be nearly the first to get a K4.. down the line probably as I have a K3S here and a K3 at the in-law's property. If I did get that 'last final rig' and it was a K4 (Iikely as I don't have much in the shack since 2000 that was not Elecraft) I would, as an older fellow then.. want the larger visual display of the computer/IF out/NaP3 sort of solution. So, do I get some IF out I can use? tnx Brian VE3VAW __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 arch...@mail-archive.com

[Elecraft] KPA1500 USB not working
For some reason, I cannot connect to my KPA1500 using the USB port. With 2 different PCs, connecting to the USZ port does not result in the creation of a virtual port. I used to be able to talk to the amp using the utility program and the KPA1500 USB, but now I cannot. Can anybody suggest things for me to try? Tnx es 73 de Brian/W3BW -- *Brian F. Wruble, C.F.A.

[Elecraft] K3 hears nothing.... my old issue of of K3S IF signals seen in P3 and NaP3 but nothing heard
You can see my message below. I think all the threads on this and responses are here. http://elecraft.365791.n2.nabble.com/K3S-IF-signals-seen-in-P3-and-NaP3-but-nothing-heard-td7653733.html In any case, though I think I had to do this a couple times, in the end that last time combined with a bit of DeOxit on the TMP connectors (male and socket) have had no issues for almost a year now. So FYI, this may or may not be the issue for the fellow who hears no signals on his K3. Note that I WAS seeing signals in NaP3, so at that point it was obvious that it was 'hearing' to a point, so the rest was somewhere and indeed was indeed within those TMP cables going into and out of the front boards. Thankfully it does not appear that I will have to resort to obtaining and installing the 'gold pins'. That would be WORK! Brian Pepperdine VE3VAW From: Brian Sent: July 10, 2019 12:36 AM To: elecraft@mailman.qth.net Subject: K3S IF signals seen in P3 and NaP3 but nothing heard A few weeks back I bought a used K3 upgraded to K3S in many ways, including a sub-receiver (which I doubt I will use). Anyhow.. about a week or so in I was in a situation where I could see IF signals on the P3 (and NaP3) but hear no signals. I contacted Elecraft service and they felt that if it persisted I might look at replacing the receiver board at the front (behind display panel) with gold pins (which could be ordered from DigiKey) but would require removal/replacement of the pins on the board. Not eager to do that if avoidable. Anyhow, by the time (day or so) Elecraft had consulted internally and responded the receiver was once again hearing and presenting signals. I left it at that, thinking well the radio WAS shipped etc. so maybe some settlement etc. Anyhow, earlier today (a month later ? ) the same thing happened. So before pulling the receiver board and re-setting it in the pin socket (hoping for a better connection) I looked at the other hardware connection there.. the two TMP plugs/sockets. So I took the two cables out with the TMP plugs on them and reset them twice. Behold, signals heard. I will let this be for now and if it does not repeat then leave it. I will let you all know if in the short/medium term the program stays away or returns. I did see ONE reference to this in the mail list archives, but the gold pins were mentioned there. Nothing re. the accessible and simpler TMP plugs. 73 Brian VE3VAW Toronto ON __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 arch...@mail-archive.com

Re: [Elecraft] K4 NR & NB
Will the NR "mixed mode" (NRmF5-x and above) where some of the unprocessed signal is mixed with the processed signal be available on the K4 as it is on the K3? I've discovered that feature coupled with the APF is an excellent way of copying near-the-noise CW signals.

Re: [Elecraft] Recommended Power for K3/100 for 100% Data Modes
One thing you might check is whether or not your K3 has thermal pads between the LPA transistors and where they bolt to the bottom cover. I ran across this when doing some mods and the instructions said to reinstall them but my early 4xxx K3/100F didn't have them. When I asked the Elecraft tech he said they were added because of the higher duty cycle digital modes. As a minimum make sure those screws are tight. 73, Brian, K0DTJ > On May 22, 2020, at 16:03, Eric KG6MZS wrote: > > Hello All, > > I’ve searched the reflector's archives and haven’t found anything on this, so > here goes. > > I have an aging K3/1000 (sn 3045) and I wish to preserve its operating life. > Up until now I’ve mostly operated in SSB and BPSK.
