I have 2 DTR650 radios that I was able to configure through the serial cable. I bought a 3rd one on eBay and when I tried to configure it to talk to the other 2, I got a message saying I first needed to upgrade the firmware.
I saw the cable costs $80. Even though is desirable to update the firmware on all 3 radios, there’s only one of them I am having issues with.
I am weighing if is worth buying it or not. I read that if you have the keyboard, you can do the programming as well. Do you think this can be an option as well? (Of course, I wouldn’t upgrade any radio, but that might also OK).
Sorry if this has already been answered, but confirming the serial cable does not work for flashing? Has anyone found a place to buy the flash cable? I’m out of luck looking.
