I tried to save my fire department a few bucks in radio programming. I was successful with a couple other portables and the Minitor V's were a breeze. But these Motorola PR400's are over my head. I bought a disk and cable on Ebay and nothing in the software says for PR400 I cant get my laptop to recognize the USB cable that came with the disk, and furthermore the radio it self doesnt even have a CP interface plug to put the cable. I see 2 holes with a dust cover 1 has a set of headphones on it the other hole is labeled with a microphone. I am usually pretty quick with these things. The disk when I load it up has so many files and what not on it i dont know where to start I see Motorola and Kenwood A8 CPS and something called HYT and a mess of Chinese folders. Any advice at this point would be greatly appreciated.
