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.

Hi all,
so all TX part alignment went ok. All resistances, voltages and finaly power
re-peaking is in spec.
Also 5W test seemed ok until I noticed strange behavior > the power
fluctuation on key down as same
as after band switching...
Short vid is here:

I am dissapointed as we thought to finish all work this evening successfuly.
I have no idea what could be wrong as I replaced K1-3 relays on band module,
checked all coils,
caps, also diodes on RF board... :(
Will be happy for any hints,
Mni thanks in advance.
