w7rf has identification controllers for repeaters. These devices will make your repeater FCC compliant as far as call sign ID requirements go. This page show cases some of the available controllers by W7RF.
There are a host of "IDers" available. Build your own repeater using two Motorola's + the ID-o-Matic. It should be noted that a "cross-band" repeater also requires automatic identification.
W7RF supports Motorola, Kenwood, and TYT on amateur radio or GMRS.
