[Elecraft] K3 SN89XX Audio Problem Help please

[Lyle Johnson]

Bill,

Try this (from K3 firmware release notes0:

MCU 4.86 / DSP 2.83, 6-9-2014

* REAR HEADPHONE JACK CONTROL: The rear headphone jack (on the KIO3) was 
recently changed to a different type whose speaker-cutout switch logic 
is inverted from the original. If speaker audio is missing even without 
phones plugged in, you'll need to change the setup. Locate 
CONFIG:SPKR+PH, then tap '1' to switch to "PH.R SW-" (inverted). Tapping 
a second time reverts back to the original setting, "PH.R SW+".
