Or , you can turn the amp on with a keying line and sweep the input with a
analyzer to see where it is matched. CB amps are notorious for having very
narrow input match networks, like Jim said, but the transformers are most
likely broad band. Worth tinkering with if you want to see whats going on..

I'm guessing that that amp is a POS. You can filter harmonics, but you
can't filter IMD. I'd throw it in the trash. The SWR issue is likely
because the input circuit is tuned for 11M and doesn't pass whatever
frequency you're trying to drive it with.
