Well that sucks. I originally tried to buy this radio off of Amazon but they instead sent me a UV-25X2 two times in a row (which I still need to return) and I finally bought it off eBay
It's a two tone beep that I hear when I stop transmitting and I have another radio to monitor my transmission and it definitely is transmitting the tones.
I just got a new BTech GMRS-50V2 and the radio is sending out a roger beep which I can't seem to find the option to turn off. I researched the manual that came with it, Looked for the option in chirp and also a google search turns up nothing about a menu option to turn this off. Anyone have a clue?
