As Brian suggested they are apart of the SC Air national guard. They have about 9 talkgroups on palmetto 800 at the moment only 5 are in the database under National Guard. I am the one who submitted them. i mainly only hear 27871 which is McEntire ops which is mainly used at McEntire Joint National Guard Base in Hopkins in Richland county. They dont talk a lot so its hard to identify talkgroups but when they talk its easy because they always mention the name of the talkgroup they are on. when i listen to 27871 i always hear the controller say '10-4 on McEntire ops'. Last time i saw a National Guard unit for ops on Palmetto 800 they were useing Motorola xts5000's.Does anyone know where I might find the radio system info for SC HART (Helicopter Aquatic Rescue Team)? Thanks!
