[Elecraft] [K3] Audio cutting out??

[James Sarte (K2QI)]

Not quite sure what's going on here; have had the K3 in storage for
about 4 months. Finally unpacked it after our move to PA and set it
up, and now audio is cutting in and out; as if it would just mute for
a few seconds (sometimes 4-5 secs) then come back to a normal level.
I'm wondering if the RF overload protection is engaging as the weather
here has been quite stormy, and I suspect lightning interference.  How
can I confirm?  It's been a long time since I've been on the air with
the K3 that I've forgotten quite a bit.

Any suggestions?
