[Elecraft] K3 - KRX3 audio cuts out.

[Bill Coleman]

I’ve been experiencing an issue with my K3, and I’m wondering how to troubleshoot it. 

Here’s the symptom.

Often, when I’m trying to work a weak DX station, I’ll switch the sub receiver off and on, so I can better hear the DX station, then to try and hunt for the station he’s working. 

Lately, after switching a few times, the sub receiver audio will go dead. Changing the sub receiver volume makes no difference, it’s just not there. Once it does this, switching the sub receiver off and on does nothing. The audio does not come back until I power off the K3 and power it back on. 

Any one else experience this?
