[Elecraft] Kx3 turns itself off

[Sean Cunningham]

Thanks, I'll check it out. I wondered if it could be the PA overheating and
did some testing. The PA.I temp got up to about 42C and it didn’t power
off, so I am guessing it is the low internal voltage issue you mentioned.

I will check with support if it continues.
