I found a ICOM marine radio for $ 5.00 at the swap meet. (Model M-55) I brought it home , it did not work and I took it apart and reset the CPU on it. Works great! If you own a Icom Radio for Marine use, you might download their service manual from the attached site. I found this site after getting it working....
