[Elecraft] K3 SN89XX Audio Problem Help please

[Bill OMara]

I have a new to me, Used K3 that looks to have a setting or audio problem I
can't figure out.

 

The problem I'm having is the CONFIG setting for "SPKR+PH" is set for Yes
and the audio is working the way I understand it to work (Both Speaker and
headphone audio at the same time).

 

But when I change "SPKR+PH" to NO I only get Audio if the Headphones are
plugged in, when I unplug the headsets NO audio comes out vis the internal
speaker and the radio audio is gone.  If I then go to the CONFIG settings
for for "SPKR+PH" and change it back to "yes" then the internal speaker then
provides audio again.

 

What am I missing?

 

No second receiver is installed if this has any impact.

 

I own two other K3 radios and they do not act in this manner.

 

 

Thanks for any help
