I think that is going to be Herman Lifeflight right? If so they are on Air: 128.85 A.M. and STAR-Net: TG 21904 and the old TG is 208, but it isn't used anymore. You can also hear them on UHF FM 1960 Fireground, High band mutual aid (154.28), HAHERN, Starnet Mutual Aid 1 and 2, and the 800 MHz ITAC channels for air-ground ops on lifeflight scenes. You also might want to check out PHI Air Med (used to be Sky Med), they use all of the same air-ground ops channels.
Edit: Yups stupid smiley lol
