No Speaker Audio / K3

[Elecraft mailing list]

Hello,
I have a K3 that just recently lost speaker audio.
No audio from the external amplified speakers I’ve been using, and nothing from the built-in K3 speaker when the external speakers are unplugged.
Headphone audio is working fine.
Any suggestions before contacting support?

Thanks!

Try Menu/CONFIG - SPKR+PH - must be "YES" for speaker to be active

In your ears or someplace in the radio?

Hello,

Mine did the same thing last month; small application of Deoxit on a  
Q-tip solved it.

To test,;
Set SPKRS+PH to yes, if audio comes back, then headphones are plugged
in, OR the switch in the front or rear phones socket is bad and telling
the brain a plug in in.
If setting SPKRS+PH to yes and still no audio, try tapping 1 while in
that menu to toggle the sensing between early (+) or later boards
(-)that had reverse polarity.
If still no audio (in speakers only), then probably a bad audio chip U1
on DSP board.
(or if you had the front panel off recently, the two dual-row plugs from
the DSP board to RF board may be UP one row of pins).
