[Elecraft] [K3] Spontaneous HI CURR, audio reduction in RX mode

[Mike K8CN]

I believe I found a potential answer in the K3 manual (to my embarrassment, I
should have looked there first, eh?) under the Troubleshooting section,
Receive mode:

"HI CUR or SPKRS=1 warning: HI CUR may indicate a shorted left speaker
channel; the K3 will
reduce AF gain."

Funny thing is that I don't use the internal speaker, just headphones
connected via the rear panel PHONES jack, and have never plugged anything
into the external speaker jack.......I guess I'll unbutton the case and see
if any wiring is awry.  The intermittency of the HI CUR warning in receive
mode is puzzling - if there's a shorted audio channel, I would think it
would stay shorted unless my headphones have an intermittent short on one
side.

Thanks, too, to Joe, 4Z7JBA, for his offline suggestion of another potential
cause for the observed behavior in receive mode.  

Mike, K8CN
