Yeah, they (baptist Lifeflight) just changed their dispatching/communications. Haynes lifeflight , which is a new service (unrelated to the other lifeflight) could possibly be using southern Linc I suppose, I don't know what there ground ambulances use, but I'd imagine it would be something similar to what the ground units are dispatched on.
Haynes Ambulance ground units in Montgomery are on 151.970 dcs311. Haynes ambulance ground units in Elmore county are on 151.910 using Digital Nexedge. I did hear one time on 151.505 with a 136.5 tone lifeflight, air 3 to air com, south tower, air heart 2. This may be a tower for Air Methods the company who owns several med evac helicopters nationwide. They dispatch out of Nebraska if I remember right.
