Brett,
Congratulations on your new and improved K2/100 station.
Yes, the PA current goes up quickly when measuring for the bias level,
and I don't know of a better way. Just repeat several times until the
initial current is correct.
The first reading on your DMM is probably not correct due the timing
within the DMM, but the second one will be the correct current. The
current will begin to climb even on the rd cycle of the DMM reading.
Make the final adjustments to the bias in very small increments, going
into TUNE and out again for each trial.
73,
Don W3FPR
