Did the radios previously work together? If so, you have one radio in need of repair.

If the radios are new to you, and you do not know if they previously worked together, it could be a simple programming problem. Take it to your local Motorola dealer to check the programming.

One simple test to see if you have one with PL and one CSQ, is to press the monitor button and see if the two radios can communicate when they are in open squelch mode. (The monitor button will be one of the side buttons near the PTT.)

Read the radio on a computer and check the accessories socket
