I am a dispatcher for the sheriff office in shelby county and we use both vhf and southern linc to dispatch. Most of the radio traffic goes out on our VHF channel (154.7850 pl tone 123.0). Everything thing else goes out over southern linc.
I have asked around and nobody can tell me who is using this frequency. However, if you happen to catch any of the unit ids let me know i should be able to track down who they are.
In the last 10 minutes I have heard the following units id: 5199, 5161, 7505, 5231 and 5251. Also heard a unit call a "Code 10".
In the past I have traffic on 154.785, then I would hear the same unit(s) on 159.960.
Also I have heard Dispatch give a "hold all radio traffic" on both frequenices.
Hopefully the link below will work - had a problem copying it: But these are the current licenses issued in Alabama Statewide for that frequency as of March 01, 2006.
