with apologies...
i understand the way different aeromed services operate.... the three central ky choppers will usually talk directly to the person from ems/fd on the scene using the local freq so the folks on the ground don't have to change anything....
the freq you are looking for, unless they use one of the med channels, is the dispatch freq or the "company" freq. the reason i suggested that you ask them for their numbers is they are more likely to pass it along to someone from an area fire department than someone like me calling from another time zone....
statcare's freq from their glasgow base is 155.265, their louisville base uses 155.400 and 155.340.... never listen to vandy and still waiting for phi to license their new freqs....
