Skipp, I have two VHF repeaters linked in-band. 146.92 with a remote base radio on the other repeater frequency at 145.45. I use GE Mastr II radios in both repeaters, and used a modified GE Mastr II mobile radio for the link. I removed the final amp from the link radio and use the 250 mW exciter through a low pass filter/antenna relay to a three element beam. The beam is about 15 feet below the DB-224 repeater antenna and causes no de-sense to the repeater. I am sure the repeater de-senses the link radio, but the result is not audible. The two repeaters are about 10 miles apart and are line-of-sight. The 145.45 repeater uses a directional antenna to cover a major highway in a canyon that is masked from the 146.92 repeater in several places.

The repeaters are on different 30 mile distant mountain top sites. One repeater has an on-band linking radio (Alinco DR-235) set up on the adjacent frequency. As an example... 224.960 and 224.940MHz. With enough physical isolation, filtering and setup... much to my surprise it works pretty well. The owner wants to now park IRLP on it and waste everyone's time. But they are his repeaters... On toward part 2. s.
