Anybody step in and correct me if I'm wrong but AIREVAC here utilizes their company freq of 153.38 / Campbellsville tower when they get airborne as there is no reception on ground due to line-of-sight. Here in the BG area they have our Warren Co 800mhz trunked capability and are able to communicate on mutaid /fire/and Med talkgroups. They also have the standard 155.16 and 155.34 stuff. When inbound to the Medical Center, I believe I have heard them using the 155.34 and TG 3216 when inbound to the ER. Hope this kind of guides you. Oh yes, and 123.00 for the airport...
