I have two P200's in UHF programmed for GMRS. Very durable and for plain conventional use they work just as well if not better than my MTS2000. As others have said, they require DOS to program and it is my understanding that the Genesis radios suffer from quite a bit of sensitivity issues with the CPU clock speed of the programming computer, meaning you may even need an old 386 or 486 CPU to successfully program them. Mine were programmed by the seller and I believe I was able to read from them to my Pentium II laptop I normally program with, but I don't think I ever succeeded in writing changes back to the radio due to the CPU clock speed being much faster that what the Genesis RSS was programmed to use.
