Bill,
Those symptoms sound familiar. I believe your KPA100 is oscillating at
about 600 kHz.
During the KPA100UPKT installation, did you change C31? There is an
omission in the kit contents and the instructions right now which is
trying to be corrected, but has not yet been completed.
If you did not change C31 to a 0.22 uf capacitor, send a note to
[EMAIL PROTECTED] and ask for one - the part number is E530295.
Installation of the larger value for C31 will stop an oscillation at
about 600 kHz (what frequency does the LP100 say is being transmitted).
Note for others following this thread - the C31 change is *only* to be
installed if the KPA100UPKT has been installed.

initial symptom was the autotuner would lock up/ & reset the radio

when running the k2 @ qrp .. the swr reads correct and the PA is
basically out of the circuit,.,,,,"1.3" .... this is on 40. both on
the set AND THE LP-100
now my LP100 is giving me a big clue what is going bad in my K2/100
PA.....
The problem is that I still don't understand enough of the basics../..
but when i dial up over 15 watts the swr reads 9.98 !!! but when i
go back to under 15 watts .... the swr reads correctly...(LP-100)
I know something is wacky in the kpa100.... and i thought it was in
the tuner...
I have just completed the last of the upgrades to the KPA , but it
appears to not have helped...
oN TYHE k2/100 the swr seems to read double when on the PA vs the
qrp,....on the other bands , but 40 has bigger /*issues...such as
locking up the autotuner... .which was the original sympton...
