I am a new Ham. I just purchased the Yaesu FTM-500dr as my first rig. The rig arrived and set up seemed easy. I can receive on several frequency that I manually programed into the unit but I am unable to transmit on any frequency. I have been checking it against my handheld. Check the manual but can not find any issue. I also tried the Yaesu mic from the control head and the main body - still not able to transmit. Any suggestions? thanks in advance.
