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

[Mike K8CN]

Over the past several weeks, and especially during the NA Sprint CW contest
last Saturday night, I've noticed spontaneous brief flashing of the HI CURR
warning *in receive mode*, which is accompanied by an immediate reduction in
headphone audio (though not complete loss of audio).  It is as though the
receiver's RF attenuator was switched in after the HI CURR warning was
flashed.  

My K3/10 is up to date on all firmware and has a serial number in the 66XX
range if I recall properly.  I have yet to discern any correlation with
transmit mode behavior, which has never displayed a HI CURR warning.  My gut
instinct is that this may be one of those pin corrosion symptoms, especially
since I've had some strange responses to front panel button presses that are
not repeatable.  The receive audio seems to come back, but I can't tell why
or when in relation to anything I've done with the radio controls........

Has anyone else seen the HI CURR warning displayed only in receive mode with
accompanying loss of receive signal strength?  I've searched the archives
and found plenty of discussion about HI CURR warnings, but nothing quite
matches my K3's observed behavior in receive mode.

Mike, K8CN
