Hi Steve!

Could you describe your antenna setup? Are you using the Arrow
Antennas 10W diplexer with your antenna? Have you tried running
coax directly from the 70cm feedpoint on the antenna to your radio,
and just try listening to SO-50? Have you put another diplexer
between your radio and the 70cm feedpoint? What type and length
of coax are you using?

Paul N8HM had previously asked if you could explain your setup a
little better. I didn't see a response to that post. If you are using the
Arrow Antennas diplexer, it is possible that something has gone
wrong with it. That happened to me with my Arrow Yagi several years
ago, where I ended up replacing the small diplexer with another one
(I think it was a Diamond diplexer, but others from Comet, Yaesu,
MFJ, and other brands could also be used). The Arrow diplexer is
not very sturdy, and some unintentional rough handling could cause
what you are describing - if you're using that with your antenna.
