Darryl, it depends, primarily, on the Q of the output tuned circuit, the
degree of loading, and the bandwidth of the antenna/ transmission line
system. Shortened antennas with loading coils have very narrow bandwidth can
be the determining factor. 73, Dan, N5AR

Hi,

I have a question that I have never seen the answer to in any amp manuals.
After tuning the amp, how far up or down in frequency can you move without
retuning the amplifer?

Rich, Thanks for the resisters, they arrived the other day.
