[Elecraft] Factory Power Calibration of the KPA-1500 - question
This may have been discussed already, but just wanted to confirm. I had a number of questions, but I'll condense them into a few: How are the KPA-1500 power LEDs/display calibrated at the factory, and what equipment is used to do the calibration? Second, in the case of using the amp with K3 and the KPAK3AUX cable, is there a point where ALC kicks in and decreases power output? Thank you! ’73 de JIM N2ZZ __ 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] K2 VFO encoder / control board close fit
Mark, The instructions packed in the encoder envelope tell you to flush cut not only the pins on the encoder board, but also the leads on the control board that might contact it. If you do not have flush (or shear) cutters, and want inexpensive ones, look for Xcelite (or Lufkin or Cooper) 170M shear cutters. They can often be found in your local Home Depot. In addition to flush cutting the boards, put something on the back of the encoder board - fish paper would be best, but a piece of flat plastic cut from one of the many plastic wrapped consumer products would be good. Paper or electrical tape will eventually puncture. 73, Don W3FPR On 5/5/2018 10:58 PM, Mark Petrovic wrote: While performing the initial power on tests on my K2 S/N 7809, I noticed that the VFO knob/display tuning test produced a sluggish, intermittent, or no change in display when I turned the knob in either direction. I proceeded to remove the two chassis screws securing the control board to the front panel board. This allowed the control board to relax and slightly fall away from the front panel board, toward the back of the radio, opening up the space between the front panel encoder board and the control board. The display was at once responsive to knob turning on all RATE settings. __ 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

You might also want to double-check About My Mac -> System Report -> Hardware -> USBto see if the K3 is showing up - mine is a 'General Purpose USB Hub' with a TI vendor IDwhich has a USB Audio Codec (Burr-Brown) and an FT232R USB UART whose serial numbermatches the device special file that WSJT-X is talking to. Also, go to System Preferences -> Network and make sure that that port is not configured.(It most likely is not, but Murphy does very strange things at times!) It wouldn't surprise me if Serial might have a permission problem/setting that's fouling you up,but that's just a SWAG on my part.

Re: [Elecraft] K3 Serial Comms with Apple Mac ?
Brandy, Actually, I wasn’t planning to do anything with the Serial app and comms to the K3. My questions stem from the fact that I have used Serial with a number of other devices (mostly Arduino, Raspberry Pi, and PIC boards) so I thought: try it out with the K3. My failure to get a response is what prompted my question. Not sure I will find anything amiss from your suggestions (already having done one or two of those types of checks) but I will try again. Now, it is a mere curiosity thing — this should work. I have successfully communicated with Elecraft serial equipment using my own serial-comms programs I have written (C and Python).

Re: [Elecraft] K3 EQ settings?
I got mine from Jim, K9YC, a retired audio professional designer and consultant in large venues. They are: 1 -14 2 -10 3 -6 4 -2 5 0 6 +4 7 +6 8 +10 I don't frequent phone much but when I do [like in an NAQP SSB or SS], I usually get one or two "great audio" comments. While most of that is undoubtedly due to superior DNA, I think the K3 TX EQ has something to do with it. [:-) Close-talking some mics tends to boost the lows too, sometimes significantly. Jim points out that there is no value to power in the low frequencies, they carry almost no information. Watching the P3 waterfall with a narrow span demonstrates dramatically how many SSB signals have all the power in the lows, crammed up against the suppressed carrier, and next to nothing out where it would be beneficial. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 5/6/2018 12:55 PM, Mike Markowski wrote: I just finished writing a python program to make it easier to control the K3 internal EQs.

When I set the KAT500 to ANT2 it keeps switching back to ANT1 so I figure it must be remembering a prior band/ANT setting. How do I make it use just ANT2 for all 5 bands?

Re: [Elecraft] K3 EQ settings?
Congrats on the DNA, Skip. :-) And thanks for the EQ info. With info sent to me off-list by a few as well on your info on-list, I see variations by Jim k9yc and Bob Heil k9eid, likely due I assume to different mics & on-air advice for different op voices - unique for each environment.

They are: 1 -14 2 -10 3 -6 4 -2 5 0 6 +4 7 +6 8 +10 I don't frequent phone much but when I do [like in an NAQP SSB or SS], I usually get one or two "great audio" comments. While most of that is undoubtedly due to superior DNA, I think the K3 TX EQ has something to do with it. [:-) Close-talking some mics tends to boost the lows too, sometimes significantly. Jim points out that there is no value to power in the low frequencies, they carry almost no information. Watching the P3 waterfall with a narrow span demonstrates dramatically how many SSB signals have all the power in the lows, crammed up against the suppressed carrier, and next to nothing out where it would be beneficial. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 5/6/2018 12:55 PM, Mike Markowski wrote: I just finished writing a python program to make it easier to control the K3 internal EQs. The impetus is to easily adjust in response to on-air reports, or to adjust when using MON to listen to myself in headphones. One of the things I've done is to include a file of presets drawing from recommendations of knowledgeable hams. An example is shown at: http://udel.edu/~mm/ham/elecraft/python/ Are there are other recommendations from anyone? I'm especially looking for recommendations coming from those with substantial audio background. The idea is for us audio neophytes to steal, er, learn from the learned! I'm restoring a Heathkit line of DX-60B xmtr, HR-10G vfo, and HR10 rcvr. The DX-60B is cw or am, so I've become interested in AM settings of late. :-) Tnx es 73!

Re: [Elecraft] [KAT500] Remembered Antennas
How many of the beacons are running now? I stopped using FAROS because the beacons started going away... I have a loop under test right now using WSPR, and my K3, at 2 watts... It will be up for the next 24 hours. 73s and thanks, Dave NK7Z https://www.nk7z.net On 05/06/2018 06:21 PM, MaverickNH wrote: I’m using VE3NEA’s Faros NCDXF beacon software to monitor the 5 bands using my K3S on bypass with a KAT500 on bypass, as my two antennas have rATUs at the bases.

Re: [Elecraft] KPA1500 SWR meter
I have the same problem with S/N 64. I thought it might be a cable but the problem occurs on all bands, both antenna outputs and into a dummy load. I'm only about 90% sure that it is related to temperature - I was too busy working the contest to do much more troubleshooting. And I agree with the fan noise comments - the pitch of the noise comes right through my Bose noise canceling headphones. 73, Bud N7CW On Sun, May 6, 2018 at 3:43 PM Don Butler wrote: > Mike I had the very same thing happen last night while operating the 7QP > contest. which is the first contest I have operated with the KPA1500 > the heatsink temperature was down in the mid 40s C at the time > and > in my case it occurred on 160 meters only SWR as per other meters as > well as the digital readout on the 1500 were reading 1.2:1 ... and did not > change even when the LED flashing occurred . but I was getting > intermittent flashing of all LEDs on the amp's SWR meter > > During the contest I was continuously running on CW with hourly QSO rates > running between the 70s and 110s I opted to manually switch on the fan > to keep the temperature below 60 degs C . level 2 seemed to keep it > there most of the time but I did move up to level 3 a few times (and > BTW, at that speed the KPA1500 is clearly the noisiest amp I have ever > owned > but, arguably, it may very well be the "coolest" also . headphones > were absolutely necessary with that noisy fan . clearly much noisier > than the Alpha 9500 sitting right next door ... which I also used during > the > same contest... > > So Mike, you're not the only one experiencing this phenomenon whatever > it is.. > > Don, N5LZ (KPA1500 #45) > > -Original Message- > From: elecraft-boun...@mailman.qth.net > [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Mike Crownover > Sent: Sunday, April 29, 2018 8:13 AM > To: elecraft@mailman.qth.net > Subject: [Elecraft] KPA1500 SWR meter > > I have noticed that after my KPA1500 gets above 50C the SWR indicator light > starts to show intermittent high SWR.

Re: [Elecraft] Elecraft CW Net Report
Could hear you when you started on 40m, but as you have reported, fading was prevalent. I'll keep trying. 73, de VE5UO On Sun, May 6, 2018 at 6:45 PM, kevinr wrote: > Good Evening, > > Conditions were less than poor.
