Stephen,
Incidentally, is it normal for the UV-5R to key up when the serial cable is present? I'm going to make a practice of always having a dummy load connected when programming this radio.
It is my experience that any RF reception breaking squelch on either of the channels during data transfer will likely fault the transfer. The receiver appears to be 'on' during data transfer.
Take the antenna off (instead of a dummy load) and/or tune to quiet channels for data transfer.
I suspect the issue is that any audio signal from the radio receiver get's blended with the data transfer signal being pushed in the thru the microphone jack, thus scrambling the data steam.
