F8ACF56,
Q9 provides the KEY OUT signal to key an external amplifier (or other
circuit) when the KPA100 PTT is actuated. Normally, this signal (tab or
drain of Q9) will measure open or infinite. It will then measure close
to 0 ohms when the KPA100 is keyed (PTT actuated).
Measuring infinite at J2 is also fine. I know the instructions say >10K
for both measurements, but infinite is fine (and > 10K).

What is your problem with the K2 and KPA100? The instructions for
alignment of the KPA100 are in the manual.
