[Elecraft] K2 & Aux Digital Mode Connection Box

[Leigh L Klotz, Jr.]

Nigel,
I am seeing thr phenomenon I described, but you must right, as I am 
taking the output after the amplifier, and that is likely not on the AF 
gain pot, so I was probably wrong citing the tap location.  I don't have 
access to my schematics or a PDF viewer right now.

I tried taking the output before the amplifier, but it wasn't high 
enough level for my sound card, and I was troubled by noise on the low 
signal.  So I moved the tap to after the audio amplifier and that is 
where I am seeing the audio pickup from the speakers.

I did buy one of Don's digital out boards, but didn't install it yet.  
Someday...
