I operate a linked GMRS repeater network that's part of MyGMRS. It uses 5 MTR2000 part 90 machines linked with Voip and covers 1/4 of the state of Wisconsin. Just like NavyBOFH said you will at some point need to make a compromise on your requirements for a total part 95 certified solution. From the title of your post "a beginners repeater" you sure had a strange list of demands, I am still hung up on the Solid-state ladder filters as I have never seen these in use in GMRS or LMR of witch I own repeaters in both services and user either duplexers or vertical separation with separate antennas.
