[Elecraft] Heil K2 Proset with K3

[Fred Jensen]

Ok Folks,

As often happens on reflectors, I have totally lost the thread on this 
subject [and I suspect I'm not alone :-) ] although I still have the 
problem.  Please note the details below:

K2 Proset purchased with K3 came with the stock adapter.  WITHOUT the 
adapter, and plugged into the rear jacks, VOX ON, VOX GN=50, 
ANTIVOX=000, and RPL.bias turned on, it works fine.  VOX works fine. 
PTT works fine.  Semi-QSK works fine.  QSK works fine [never really 
liked full QSK].

FPL.bias turned on, gray Proset plug inserted in the mating adapter 
socket, 8-pin connector inserted into the front panel plug, VOX ON, VOX 
GN=50, ANTIVOX=000 -- No SSB, no VOX, no PWR OUT.  All CW functions work 
fine.

Numbers of folks, including one of the Chief Elecrafters, advise me that 
the FP config in the paragraph just above this one works for them, 
leading me to believe that my problem has exactly nothing to do with 
pins 5 and/or 6 of the 8-pin mic connector.  This is further borne out 
by the word to me that mic bias goes on the audio lead anyway.

I have discovered that if I tap XMIT, it goes into transmit but there's 
still no audio, however tapping XMIT again won't clear it and it stays 
in transmit.  I believe [word from the K3 designers again] that this has 
something to do with a missing ground on the blocking cap on the front 
panel, which I have not fixed yet.  If fixing that solves my FP audio 
problem, I'll be sure to let everyone know.

Meanwhile, I will use the rear panel connectors which is what I want to 
do anyway [I think, haven't actually installed the rig at the opr 
position yet].  Boy, is that receiver great!!

73,
