I have a pair of Motorola Talkabout 5500 two way radios which I want to use with another pair of Midland LXT 345. The thing is while the Midland receives any transmissions from the Motorola, the Motorola on the other hand does not receive any transmissions from the Midland. Hence its more like a one-way communication between the Motorola and the Midland. Both the sets are on the same channel (channel 1 @ 462.5625 MHz GMRS/FRS as specified in the manuals of both the sets) and work fine within themselves just not amongst themselves. Can someone please guide me as to how to get the sets working with each other? Thanks for all your help.
