Listening to some stuff happening yesterday, fire requested PHI then shortly after someone else came on and said PHI was too far out and dispatch needed to call for St. Joe's Med-Trans instead. I've heard the medical helo talking on some of the fire channels, but I don't believe I've heard them directly talking to anyone else. Since it seems PHI was replaced, their information is still showing in the database, but nothing is mentioned about Med-Trans. Just curious if anyone may be catching them on the PHI freqs or if they have other means of communications?
