UHF Freqs
The UHF Bham and St. Clair County frequencies that AmCare / StClair EMS used are actually licensed to GTS Communications, if I remember correctly. There is one site in Bham and another site on Bald Rock Mountian in St. Clair county. The repeaters had a multi-tone repeater panel on them and there were other users on the Bham repeater besides AmCare. When RPS bought AmScare last year they stopped using those and there has not been any traffic on them since. The repeaters were still up and functional the last time I checked tho....but that has been several months back.
The UHF link frequency that RPS had used to be between their Shelby County dispatch facility in Saginaw and Bluff park. There no longer exists an RPS dispatch in Shelby County. I would guess if you are in the path of the pattern of the yagi antenna between Saginaw and Bluff Park that you would be able to hear traffic on that frequency. I know the antenna on the Saginaw end was directional, and I am fairly certian the antenna on the Bluff Park end was directional as well. If it is still used you should be able to hear a "repeat" of everything the VHF reciever at Bluff Park hears go out on that link frequency; so both the units and the dispatcher.
I am unsure if the link is a simplex or duplex link. If Carl is only hearing unit-to-base transmissions on 460.525 then check the transmit repeater pair of 465.525 and I would bet it is likely you will hear the dispatch-to-unit traffic on that frequency. Sometimes when agencies are licensed to a repeater pair and they want to utilize it and not loose the pair they are utilized in that manner to avoid having the pair re-assigned to another user.
I am also uncertian how the dispatch office that is now in Jasper keys up the VHF transmitter at Bluff park, whether it is by tone remote or bi-directional link of some kind. There is still traffic on the VHF system in Jefferson and Walker Counties from time to time, but the majority of their traffic is on Souther Linc.
