Scott,
Yes, the problem is with the KPA100. The most likely thing is that
diodes D16 and D17 are damaged which results in the KPA100 not being
able to tell the K2 that power output is being developed, so the K2 just
increases the power to the max in an effort to obtain a power output
indication. At setting less than 11 watts, the base K2 is probably
producing its maximum power output as well which will be in the 10 to 15
watt range.
The most probable cause for D16, D17 failure is a lightning surge - it
is always a good idea to disconnect the antennas when not in use. I
switch all my equipment to a dummy load unless I am actively operating.

Hello
My K2/100 just recently started going to 100 watts output
as soon as I set the output to 11 watts or greater.
I disconnected the amp, and am back to the qrp version and
everything works fine. So I asume the problem is with the
amp. Am I correct?
Thanks
