    My iCom IC-751A has developed a glitch and I have no idea what might be causing it.

    Shortly after I obtained the radio, I read about the volatile memory and how the radio would quit operating if the soldered-in coin battery ever died. I replace the board with a non-volatile memory board made by Piexx and the radio operated flawlessly afterwards. Now it's developed an issue with the programmable frequency memories in that I can program a memory and it will remain in memory until I program another memory channel. When I program another memory channel, the first one I programmed disappears. It's like it will hold only one channel instead of the 32 channels it's designed to.

    I replace the battery on the Piexx board and the problem still exists. It's not a major issue as the radio still operates just fine in VFO mode and I have the external keypad that allows quick entering of frequencies.

    Anyone else ever have the problem and, if so, how did you cure it?

    People get old and lose short-term memory.

    Your board may have the same issue. Try speaking to it in a slow and understanding voice.:)

    Just to check: you are selecting a different memory number each time, right?

    I would exercise the connectors to the Piexx board (and also the other end if available without too much disassembly) and see if that fixes it.
