With a a 10% duty cycle I can hardly see any of these radios as a repeater of any kind. There is Motorola software that runs on XP but if you have a glitch while uploading the codeplug to the radio you will likely brick it. I think there is a Yahoo group for these radio and if you join you can get the software I think it's call Motorola Man. And probably get instructions to make a cable. If I remember the radio has an RJ45 connector and only two pins are used. But you better do some research if you are consider buying these radios. Just a friendly note from an old Motorola repair dude.
