Ed,
I guess the reset command can be our best friend sometimes. Kevin
mentioned the possibility of being in split mode, but I'm 99.9 percent
sure I checked that as part of the head scratching process.
As you said, these modern radios can just get a bit flaky sometimes.
BTW, I think I heard the ST0R guys work you on 20 SSB Friday of last
week. I was listening to the DX side of the split as they worked 6 and
7 call areas, and pretty sure I heard him work K7UC. I haven't spent a
lot of time looking for them, but did get them on 20 CW and SSB.
