I don't see a base on the Air Evac web site for Whitley County (it hasn't been updated with the Danville Base, yet).... but you should be able to hear them, at least one side, depending upon where you are when they transmit) from the freqs they have in place... Albany (152.95250), Harlan (173.32500) of Campbellsville (153.38000) on the Kentucky side of the border... The freqs for the Tennessee side of the border look to be kinda far away for effective comms... do you have the "N" Numbers from the choppers? When I get the chance I'll dig a little....
