Wayne, 100 percent headphone operation here. I have not done the RFC47 Mod. I have it but I was not going to tear the radio apart with no backup. I have my 2nd K3 on the way in the brown truck. I am going to build that first and then do the mods on the older K3.
Any suggested settings for serious contester types for the radio? I am not sure what AGC PLS does but mine was set to auto. Maybe off would be better? AGC Thr was 5 I will try 3 as suggested. AGC fast was 120 maybe faster? "A slip of the foot you may soon recover, but a slip of the tongue you may never get over."

I'll discuss this with Lyle, KK7P (our DSP engineer). I don't think this has anything to do with "desensing" if a narrow filter is being used. I can't imaging what might cause it with lower-level signals. The ADC has plenty of resolution, and the DSP has plenty of horsepower, so there should be no difficulty in separating out multiple stations in close proximity. There are only two things I can think of: the AGC may be set too "flat", or, if a speaker is being used at moderate to high output, that perhaps the RFC47 mod hasn't been done (on the RF board). In any case, we'll look into it. tnx Wayne N6KR --- http://www.elecraft.com ______________________________________________________________ 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 ______________________________________________________________ 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
