Confirmed, but with a few differences. In my case, I found: 1. I don't have to actually be in SPLIT mode.
2. It doesn't seem to depend on the VFO-B frequency. 3. VOX on/off doesn't seem to matter, manually entering transmit with the XMIT button seems to be the trigger. 4. It's frequency dependent. That is, if I tune VFO-A to 3.535 and tap the XMIT button to enter transmit and then tap it again to enter receive, the receiver is dead. (By "dead", I mean I hear noise but at a very reduced level.) If I tap my paddle, the receiver comes back immediately. If I do the same thing at 3.530 or 3.540, it doesn't happen (i.e. the receiver always comes back fine.) Interestingly, I DON'T see this behavior at 3.515. 73 -- Joe KB8AP On Oct 19, 2009, at 5:03 AM, Mark C.
