Radio Tx works on USB but not on wireless telemetry radios

Hi. Has anyone encountered the radio tx not working via wireless telemetry radios (no visible input in  even in radio calibration) but work perfectly via USB cable? This is in Mission Planner. The telemetry radios are communicating properly (i.e. linked and sending/receiving data) and the MP is displaying correct sensor data from the APM. I am currently trying ArduRover firmware. I never encountered this before in ArduPlane. Any help/ideas will be appreciated.See More
