Where they are used, what is a typical example of a remote control system for a repeater? In other words, to provide the ability to shutdown the repeater remotely, by means other than the input.
I think this has been touched on briefly in the past here but I was unable to find anything in the archives. Specifically, what about the receiver antenna connection? We have access to only one feedline connection. If the control receiver is in the same band as the repeater (VHF in this case) could a divider be used off of the duplexer RX port to connect to the remote control RX? Would a cavity be needed also? As for the rest of the system, my inclination would be to use a DTMF decoder output to control the PTT line. Any input is appreciated. 73 Paul - KC0HST
