I was looking around on 15m this past weekend for that elusive multiplier
during the Sweepstakes and I noticed my exciter was folding back power as a
result of a high SWR between it and my amplifier. The SWR between amplifier and
antenna was great (handled with Palstar AT-Auto Tuner – modified to accept two
SO-239 inputs).
Since I was on a SteppIR at the time, I set my tuner to it's 'bypass' mode. I
still had a high SWR between exciter and amplifier. Last night while playing
around with it, I decided to add a low power tuner between my exciter and amp..
Bingo, full power out.
The Palstar AT-Auto Tuner disables the exciter's internal ATU function, do I
have to add a 'tuned' the length of coax between exciter and amplifier or
should my Alpha be happy?
