Ah, yes: "Lent the rig for Field Day use". I did
that only when I could be there and could watch
such things closely.
My only loss was a sledgehammer I loaned. It came
back "repaired" with duct tape, and totally
useless. I've kept it that way and a reminder
about the risk of loaning things for use at Field
Day :-)

The long history was that a few years ago I lent the rig for Field Day use and
something unknown went wrong. There was a nut that came loose inside the rig
and there might have been a short circuit somewhere.
The rig was sent back to Elecraft for diagnosis and repair and it was fully
worked over including all the mods including gold pins. It came back fine and
I did not open the case between then and this year's Field Day power transmit
failure.
After Field Day I re-flashed the firmware and recalibrated transmit and it
worked fine again although it did not get heavy use as my main antenna was down
for servicing.
The synthesizers were upgraded about two weeks ago without a problem.

George,
Does your K3 have the gold PA pin upgrade?
Are the nuts on the filter cap studs that mount the circuit board tight?
