First, I'm brand new to GMRS and this is my first radio (received yesterday). Any issues are most likely me! My UV-9G will not make any sound when hitting the transmit key and the screen light stays dark. I have tried various frequencies, yes the volume is up, the radio is on and I tried a reset. I just watched a Notarubicon video on CHIRP and check to see if the PTT button was locked out and it is not. Any other ideas are appreciated.
