Some years ago I learned to take only expendable
items to Field Day: Myself :-)
Otherwise I give items to the Club: Those things
always seem to survive!

I guess I've blown the speaker amp IC in my K3
again. This is the third time this has happened,
twice in one radio and once in another.
In this case, the radio had both the AF Output
Mod Kit (pair of 470 ohm resistors) and the
E85056 Audio Protection Assembly Circuit Board
installed.
I was operating on Field Day, with headphones,
as I usually do, when some onlookers wanted to
hear what was going on. I flipped
SPKRS+PHONES=YES, then along came a strong
signal, and poof! no speaker audio.
AGC SLP was zero, and AGC THR was 020. Front
panel AGC was FAST.
This failure is really getting old, especially
at $120 a pop to get it fixed.
