[Elecraft] K1 manual revisions

[Bert]

Hi Petr,

I've checked you video and interestingly enough I have the same or 
similar problem with my K1.

Sometimes the power output goes to the full programmed output and pulls 
back 1 watt or so. It doesn't
happen every time I transmit but quite often and I can't figure what's 
wrong.

Looking forward to find a solution for both of us.
