Opps did that wrong, Sorry, I've been using there HobbyPCB RS-UV3 for over a year now and had very good luck with the radio and have a couple of them. I've been using RX PL never tied the TX PL. But there is one thing you have to use the latest firmware and use the Windows Program not the command line and that was from the guys at HobbyPCB. 73, Marty KD4HLV
