IC-F121 Programming

[K7MEE]

My dilemma....

I have 2 F121's. I can read and write to the one we use as a base radio. I have the other mounted for mobile use. It will not read or write. I have contacted our local Icom vendor and the tech ran through with me everything to check which I had done prior to calling him. He is thinking that something has quit internally. The radio still functions, just won't read or write.

So, my questions are; Has anyone else ever had this problem? Is there a way to reset the radio to default to see if that may kick start something to work? Any suggestions?

Thanks

Are you using the same computer, same cable, and save version of software? I believe the most recent version of the programming software is v1.7.

Hi, Here is what you should do, use a multimeter and check the Front panel pin 1 of the Mic radio jack, probably you do not have 8 Vdc to supply to your RS 232 interface cable.

The easy way to check the 8V is to remove two side screw and you can check on the board.

Or if you can a USB interface cable and test it easy that way, because USB interface do not need supply
voltage from the radio, they use 5Vdc supply from Computer.

In your F121S remember pin 1= 8vdc, pin2 is TXdata, pin8 is RX data, and ground is pin 7 , and that is
all you need to read and writr to the radio.

I hope this help.
