Thats a normal thing to hear on 340. Mercy Flight uses 340 often. It used to be posted in the DB. If I recall correctly, due to the transition to the UHF "Countywide EMS", 325, 340 and CW EMS are all patched together. Its still programmed in all the VHF radios in my agencies rig. As an EMS provider, I only use it like every blue moon because I can just call on the phone and give a whole lot of information and have a legit conversation with the doc. Thats how the majority of providers are doing in it the area
