I believe the K3 "may" have a power spike on

as things
settle I may try it. I use the MFJ 600 watt auto tuner with the 2KL
and
generally it works quite well. I was not happy with a AT-500 I had.
I was also of the firm opinion not to use ALC, but as my K3's power
output fluctuates a lot in SSB and sometimes for no reason also trips
the amps in CW I have ordered the ALC mod to make sure I protect the
amp.
When I set power for 50 watts output and confirm this power level with
"TUNE", I easily get 65+ watts on SSB within a few seconds after
keying up and start talking. Then slowly the power settles down to the
set level or even below. I will do the mod and hook up ALC as a safe
guard and keep it that way until Elecraft finds a solution to my (and
others) fluctuating power problem.
