Author Topic: ICOM IC-745 Cannot Change Modes  (Read 532 times)

I have an Icom IC-745 that has been stored since 1995. It was functioning perfectly when I stored it.

Now when I apply AC power, the receiver turns on, but neither the Mode switch or Ham/General Coverage switch functions.  The digital display works, memories I had stored are still in place, but the radio seems to be in a receive mode that is not CW, SSB, Am, etc.  It kind of sounds like FM.  Depressing the mode switch should step through all the various modes, mut nothing happens.  The radio has the original Lithium battery, but if it was bad, I don't think the memory channels would be retained.  Anyone have any ideas?

Thanks

I am not sure what happens when the battery fails, but I know it is used to store the whole operating code for the rig. That is the first thing I would suspect, in which case the radio (or at least the microprocessor board) has to be reprogrammed by ICOM. I'd check with the service notes on the ICOM website, and then maybe call them and ask for advice. Good luck!
