Mine died on me and have not been able to figure out what the problem is, in the meantime, I need to get a replacemet for it as soon as possible because I use it extensively at work. Myself and the local "CB" shop here have not been able to determine what the problem is with my radio.It quit transmitting a carrier on a.m. and when switched to sideband it DOES transmit a carrier. When a signal is introduced on a.m. it will move the meter slightly. In the meantime till I can figure out what to do with it. I'm just going to purchase another on to use.
