I've got an old Kenwood tm 241 2 meter mobile rig that has basically gone unused for about the last 10 to 11 years. I hooked it up the other day and it works, but the controls don't work right. The dtmf buttons are totally done and the vfo knob, up down and front panel keys don't always work correctly. Sometimes they do other jobs than what they are supposed to. This radio's never been mobile or beat up. It was in my shack. I'm just wondering if anybody has some idea what I could look at to get it working right?
