Well, I am in a mess now. I have an Icom F4GS I want to re program, I have the dongle, found the driver and software but can't find the serial number to install the software. The computer this was originally on no longer exist. Problem here is it is no longer supported by Icom, dealers don't have it and looking like some top secret, unobtanium information. Can any one help here or do I have something for dumpster fodder.
