Re: [Elecraft] K3 extra xmit frequency

[Richard Fjeld]

Just a passing thought.

If your friend was using an SDR pan adapter arrangement, it may have 
been an image.

Re: [Elecraft] Elecraft] K3 extra xmit frequency

[Fred C. Jensen]

FWIW, I worked a station in NAQP SSB, and then tuning down, heard him weakly 
and distorted but understandable about 4 kHz down. He had complimented my audio 
and when I said "K3" he said "me too.

Re: [Elecraft] K3 extra xmit frequency

[Don Wilhelm]

Bill,

Both the signal 18kHz lower than your VFO as well as the chirp are 
certainly not normal and may point to a problem with the synthesizer.
I would suggest you swap the synthesizer boards between the main and the 
sub as a test, and if that cures it, you may have a simple fix of 
contacting Elecraft to arrange a swap with the bad synth board.

OTOH, contact K3support if it is not fixed by the synth board swap.

Any ideas on the cause(s)??

p.s. sure would be nice if I had one of my S line rcvrs operating to gain 
possible causes right in the shack!
