This question is likely too simple, but I'll ask
anyway: What is the "fool-proof" way to tune an
amplifier?
My amplifier is a Command HF-2500 and was used
this weekend for the SARTG RTTY contest (and it
was the first time it was ever tuned up by me on
a band desides 20m).
Somehow in tuning up on 80m with my antenna all
preset etc, I found a combination of settings in
which power out seemed to peak (a local peak).
Upon increasing drive and going to operation, I
noticed a lot of grid current. It took little time
to discover that the problem was mistuning, but I
must admit that sometimes tuning things up I feel
like a monkey twisting dials.
Can you help in providing a "fool-proof" solution
to tuning (one that works in the middle of the night
in the middle of a contest etc)?
I like to take the very best of care of my equipment
and hate to see excessive grid current even momentarily
(2x3cx800's).
Thanks in advance, Brian
