About motorola t5720
Hello, Thanks for requst me, As far as I understood, you have same settings in both radios, you mentined QT this is the 3° requirment to recive a signal, 1° channel, 2° subchannel (ctcss, pl, etc) and the 3° QT.
if you are using QT you must to send a Call from the other radio, I recomed to set the QT to Off in both radios and tray if you can communicate in both directions.
if does not receive, there is the possibility that one of your radios the Sub channel decoder is not working.
If you could test your radios with a Third radio to know wich radio is not working right.
