Re: [Elecraft] OT Headset mic
Hi Dave, From personal experience, I would recommend the Yamaha CM500 headset as a good one for this application, very sensitive high output electret mic. 73, Eric VK3AX.

[Elecraft] Preferred settings for 80 and 160?
Hi all, My K3 arrived a week ago and I am trying to tweak it for 80 and 160 CW. Does anyone have any suggestions for what settings that they found worked best for them? I know it is personal preference but I would really appreciate what different people have found for AGC THR, AGC SLP, and the other gain settings.

Re: [Elecraft] [K3] receive on ssb--DSP problem?
Hi all; It has been a week or so since my question but have not had time to give an update. First, I received several good suggestions (Wayne/N6KR suggested that check the settings for the filters, and Brian/K3KO mentioned that it might be a squelch problem), unfortunately nothing helped, and in searching each parameter I found even more rare behaviors! My last resort was to load up a previous saved configuration (also suggested by Olaf/LA3RK). I loaded my last config file--and everything worked great! I only had to return the Dual Passband setting and the CW pitch to where I had them and I was content! I live in a not-so-good location for ham radio (mountains on all sides!), but even with time off to help around the house to get things ready for the holidays I still had time to make 112 contacts during the 10m contest to get Hidalgo at least activated! Thanks for all of the advice. It is good to belong to a group to which you can turn to the members for help, especially here where there are so few clubs! When Santa delivers my KAT500 I am sure I will have othere questions--hi, hi! 73, good DX, and great holidays!

[Elecraft] K3 and phasing noise cancelling systems
I've been having terrible RFI issues on the low bands, sometimes its up to 10M but usually its from 40M down with 160M being the most affected. I've become aware of the MFJ and DXEngineering phasing noise cancelling systems and how well they work to null out interference. I'm leaning toward the DXEngineering NCC-1 although the price is very high and that is holding me back from buying one right now. I have Amtrak 100' from my Inv-L transmit and HI-Z Triangular antennas and Amtrak's 25KV arcing is killing me on the low bands. I'm wondering if anyone here has a steerable antenna system similar to the HI-Z that they use for Rx with their sub receiver and... one of the MFJ or DXE phasing/noise cancelling systems. If so, how do you have your K3 set up to handle the different systems and how do you connect your noise cancelling unit so as to still steer your Rx antenna?

Re: [Elecraft] K3 and phasing noise cancelling systems
I have a NCC-1, and it works well. My antennas are a vertical-firing cubical quad for 75 meters (NVIS antenna) and a low 80-meter dipole (noise sense antenna). I do not have a steerable array. Keep in mind that the noise cancelling unit will null out noise from ONE direction only. If you have multiple noise sources with signals coming in from different directions, you may be disappointed. It does a bang-up job on the neighbor's plasma-screen TV. - Jim, KL7CC On 12/17/2013 5:58 PM, Gary Smith wrote: I've been having terrible RFI issues on the low bands, sometimes its up to 10M but usually its from 40M down with 160M being the most affected.

Re: [Elecraft] K3 and phasing noise cancelling systems
A couple of years ago I proposed that Elecraft modify the firmware in the K3 to allow the phase of the local oscillator in either the main receiver or the subreceiver to be adjusted in some way (possibly by using a couple of front panel buttons to be used as increment/decrement controls). That would allow anyone with both receivers to put the K3 into diversity mode and sum the signals from two different antennas in order to null directional interference (noise or QRM). It would also allow anyone with separately fed stacked antennas to play around with arrival angles. The absolute phase angles would be indeterminate and the absolute phase would vary for every frequency, but nulling at every frequency would still be possible. The nulling could even be done at the audio output since relative phase is preserved in the frequency conversion process, but I assume that it would be more practical to do it where the the majority of the DSP is already being handled ... i.e., at IF. At the time somebody at Elecraft agreed it should theoretically possible and might be worth pursuing, but nothing ever came of it. In any case, I've always felt that it was a nice opportunity being squandered. I think it would be a nice plus for the K3 to be able to do it's own spatial discrimination. 73, Dave AB7E On 12/17/2013 5:58 PM, Gary Smith wrote: I've been having terrible RFI issues on the low bands, sometimes its up to 10M but usually its from 40M down with 160M being the most affected.

It should not be too hard on the K3 Rx side with 2 identical Rx paths phase coherence in bothe local oscillators. I believe it is technically well worth pursueing. Eric VK3AX.
