The Baofeng GT-5R is a GMRS radio. It is the latest one that is approved by the FCC. It doesn't allow transmission on any frequencies that aren't GMRS by default. But I can manually enter the GMRS frequencies and it transmits fine. It's way faster to use CHIRP to put in all the frequencies and also frequencies that I just wish to monitor such as Fire, etc. So it works as advertised unless I download from CHIRP. I have tried using a fresh sheet in CHIRP after resetting to factory settings and it shows in the duplex column off which shows it won't transmit. So I changed each one of the duplex settings to none one at a time. (have done this three times now) and then load to the radio and it won't transmit. When I go into CHIRP to see the saved settings sheet that I changed to none, all the settings are at off. Don't know if this is a bug in CHIRP but thought I'd see if anyone had a fix before I contacted them. This is my first GMRS radio ever. I've read through the manual and don't even see in the settings where you change the transmit/not transmit settings. Have watched several youtube videos and made sure that transmit in the CHIRP settings was enabled and I'm out of ideas. Think I'll put this one in a drawer for now. I have a better radio back ordered (Wouxun UV9GX GMRS) which is pre-programed. Thought it would be fairly simple and 2 weeks in and quite a few hours and if I thought it was a bad radio I'd smack it with a hammer, but I think the radio is fine and being new I just don't know how to effectively use CHIRP and the settings. Any suggestions would be nice. Thank you everyone who has responded so far. I'll start from scratch tonight and use the suggestions and give it one more go. ?
