[Elecraft] K3 audio issues

[John Simmons]

I bought a second K3 (used) after being a happy owner with the first one 
for about 5 years.

The radio worked great for several weeks and I used it as a remote while 
on a 3 week vacation. Now I'm seeing some problems. Hopefully it is 
something that I have done wrong!

#1. When I press any button on the front panel (e.g. A/B, MODE, etc.) 
there is no beep.

#2. I cannot get the radio to transmit power in SSB using a known good 
mic into the front panel jack or using the line in on the rear panel. 
Matching the menu settings to my first K3 does not provide joy. Using 
the rear panel mic input does work.

TIA and 73,
