I have no idea if that talkgroup is used, or if it's even the agency you are looking for. For information on something this specific you might get more help in the Ohio forum. You can ask a mod to move this thread over there.

Marcs TG xairevac is for use of fire/ems agencies to talk to the birds when coming into a LZ for information. AELT also gets dispatched on xmedflightdsp every once in awhile.
