I am testing with my HT as well as MXT500, I can hear my transmission from the RA-87 on both my HT and confirmed with my MXT500. However I cannot receive transmissions from either. I have held 2 way conversations over the repeater with both radios as well as a side conversation with another user while trying to test the setup via my MXT500. Steve Shannon…. Set tone instead of TSQL then set RX tone and TX tone both to 123.00? WRKC935can you explain tuning steps? I have researched that and was under the impression that it is primarily for non GMRS use?
