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.
73!

I still can't hear SO-50. I've checked out the receiving radio and it works just fine. Has anyone ever had a problem with the UHF portion of an Arrow antenna going bad? Loose connector?
