I have several UV-5R's and they all work great with each other, however I can not get them to talk with other radios, in this case the QYT KT8900.
UPDATE: turns out it was the RF module inside, it was fried, I took it to my local shop he replaced a diode and it words great now.
I have also tried talking to gmrs/frs radios (just to test) to see and same issue (not sure if gmrs had PL on or not however) but I do know there is no code set in either radio when I test them.
Please any suggestions would be great.
