XPR6550 no tx modulation
Posted: Wed Feb 29, 2012 4:23 pm
I have (3) XPR6550 portable radios all that are running in digital mode. Everything is working fine on the radios except there is no tx modulation on all 3. They are running ver 1.6 firmware. The tx audio does not work on the side connector with a new speaker mic either. Does anyone know if this is a common repair with these radios, or if there is a simple fix such as updating the firmware?????
