Wayne, If your repeater situation is like most, antenna not on 5000 ft mountain, a repeater 165 miles away would not be a problem for you. The users of it would be the interferring parties, but at 165 miles don't think a problem.
I would simply chose a freq 25 kHz away for the control receiver, T off the receive side of the duplexer, CTCSS or PL the control rcvr and connects its output to the control input of the controller. Things on the ground are typically cheap and easy to come by. Things in the air is what gets you. If you have a 2 meter repeater at same site could also use this same UHF receiver for its control also. 73, ron, n9ee/r Ron Wright, N9EE 727-376-6575 MICRO COMPUTER CONCEPTS Owner 146.64 repeater Tampa Bay, FL No tone, all are welcome.
