[amsat-bb] Mode B operating question...

Devin,


I use the Baofeng UV5R and a Wouxon for the FM sats. Both radios work excellent and are so portable along with my arrow antenna. For receive and having to adjust the receive frequency, I prefer the Wouxon only because it has a knob on top of the radio to tune the freq. I use the Baofeng to transmit and the Wouxon to receive. I prefer full duplex.

Good luck,

chad
