Re: [Elecraft] Your opinion on K3s settings for best weak signal cw reception
I use an audio spectrum display - Spectrogram - to fine tune a barely there weak signal. Set tuning rate to 1 Hz - the APF peak is less than 10 Hz. Set the frequency cursor in Spectrogram to your pitch frequency. Set the DSP bandwidth wide so the NR works effectively ~ 700 Hz. Use NR mode ~m5-3 so the APF has some unprocessed signal to work on. It takes practice but works. 73, Brian, K0DTJ > On Feb 11, 2020, at 18:05, bw...@fastmail.fm wrote: > > Would anyone be willing to offer suggestions/recommendations? > Your setup of the K3s to maximize weak signal cw reception? > I especially would like to figure out how to maximize the APF without ringing. > > Sincere thanks > Duane > __ > 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 huntin...@coastside.net __ 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] KXAT2 Memory Failure/Malfunction?
Have owned KX2 #3007 for a little over a year. I recently had to replace my at-home antenna because of weather (wind) damage. I initially tuned the new antenna every 20 kHz through the 80/40/20m bands, and had no issues with matching on frequencies between tune points on first use (1.0-1.3 SWR) Since then, the ATU needs to be re-tuned each use as the SWR on power-up is usually 25 or greater on the last used frequency. Note that the antenna is disconnected when not in use. Any ideas?

Re: [Elecraft] [Elecraft-K3] What's your favorite MACRO for the K3 or P3?
I use a Genovation Keypad, as described at: https://www.nk7z.net/adding-external-keypad-k3/ As an example of just how versatile this is-- I tune in a DX station on the K3, then hit the SPOT button for a CW station to preset things. I then press a single button on the Genovation, and the following happens: 1. The P3 bandwidth is set to 6 KHz. 2. The DX station is moved to the left side of the P3 screen. 2. The 6 KHz above the DX station shows the pile up spread out. 3. VFO B knob becomes the transmitter tuning control. This allows me to find a hole in a pileup using the transmit cursor on the P3, tune to it, using the VFO B knob, and then I hit the "ID" macro button on the Genovation, this sends my call in the current mode. This makes busting a CW or SSB pileup really fast and simple. I hit a single button on the Genovation, (presets everything), move to a clear frequency using teh VFO B knob, then start hitting a second button, (sends my ID or launches a memory of my voice), till I get the station... The Genovation is a 64 external keypad that plugs directly into the P3 where the keyboard should go, no adapters, it just plugs into the P3. This gives me 64 macro launching buttons, external to the K3/P3 combination. It is slick as hell to use... I have macros for bandwidth control, mode setting, RTTY setup for the K3, (DATA A vs AFSK A), at single button press, Power control, memory launching, etc... I have a spread sheet of all the above macros, and a few more at the URL above as well. All the software that is needed save the Genovation itself, is available on my site. Genovation has given me permission to distribute a modified version of their Genovation control software which runs in the Genovation keypad, and allows it to talk to teh P3 keyboard input. You can get the Genovation via Amazon for around a hundred bucks... 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist ARRL Asst.

I have been trying various combination of IP addresses and ports using a wifi hotspot that is outside my home network . Emulating what will eventually be the setup when I move the KPA to my remote site. I want to turn off the PC at my remote site to save power!

Re: [Elecraft] QRO - KPA500 Failure
Hello Ed, I don't think that you are in class AB with 80% efficiency, in fact you cannot be. Class B can theoretically achieve 78.5% but this is seldom achieved in practice, especially on VHF. Most likely there is a problem with instrumentation.
