I'm wondering where a couple of med copters are based out of, ever since I put up mine new antenna the other day I can hear them clear as day. The one I was hearing just a little bit ago was memorial star and the other was something like sierra gulf 1, not quite sure on that but it was coming through on the med chs. I'm just amazed that I can hear these clearer than the area based heli's, like AL 72 and Medevac 1 and 2.
