[Elecraft] K2 - starts in transmit mode

[James C. Hall, MD]

Hello:

 

I hadn't started up my K2/100 in awhile and I wanted to give it some
exercise today. When I hit the power button, I was surprised to see it in
transmit mode with a hum/tone coming from the speaker. I immediately shut it
down, disconnected everything and hooked up a battery and a dummy load and
set the power to minimum. Pushing the power button revealed the same
symptoms - increasing the power showed the LED power meter increasing in
power until it got close to 100 watts and then showed Hi Cur. I powered down
and then shut it off.

 

I don't know what to try next, that is before attempting to do a MCU reset.
Any ideas would be appreciated.
