[Elecraft] [K3] multiple error messages on start-up

[John Shadle]

This is odd. Just finished a QSO with J5UAP on 30m this evening and
then switched over to 40m to pursue some more DX. When I got there, I
wasn't able to get any power out. It showed 0.0W when I tried to TUNE
(I have a remote tuner at the base of my vertical).

I power cycled the radio and then received a multitude of errors upon
power-up (including ERR IO1 and ERR PL1 among others). In addition to
that, the fans were running (I have the 100w amp as well).

I turned the radio off for a minute or so, and now the error has
resolved. I've had the issue of the no power out when TUNE-ing in the
past, but never this before.

Help!
