Hello! Thank goodness for this thread. I was beginning to think my TD-H3s were defective. I programmed some repeaters on channels 90 and above with the intent to use those when traveling. But, when I went to test, all I get is the "beep" notifying me that I cannot transmit. I tried resetting into "normal" mode and into GMRS mode -- same effect. I realize I'm new to all of this, but was wondering why have a programmable channel if it cannot be used to transmit? My solution for now is to try and save the repeaters to lower memory slots.
Edit: I used Chirp and the TD-H3 Windows application to do the programming. Both had the same results. Both radios are running version GMRS_250110.
