Thanks much. There was another freq that I heard them on that is no longer in my radio. Probably because it was also used by a school district in MS and I didn't have the ability to tone it out. There was a DB of TN medical helo freqs on RR but I'll be damned if I can find it. I hear Memphis MedCom talking to the ER at the Med on 463.15/468.150 via a patch from .340, 205 or whatever else they might be using. Last time I paid attention, not nearly as much helo traffic heard on the usual freqs. I do know that the Memphis MedCom doesn't dispatch the Memphis helos anymore, thus the freq that you hear along with the one I have forgotten. I'll do some hunting.
Thanks again.
