North Mississippi Air Med
Hospital Wing (Wing-1, Wing-2, Wing-3) out of Memphis almost always gets the call to Desoto, Tunica, Marshall, & Tate counties in Northwest Mississippi. Tupelo also has a chopper and they usually get Northeast Mississippi. Hospital Wing is normally dispatched on 155.340 or 155.280. Also traffic on 155.205. I hear patient info, dispatch location, doctor info, etc. on 155.340 but have also heard it on 462.950, 463.150 and 463.175. They talk to ground units on 155.340 or 155.205.
