SC Forest Service uses analog vhf and sometimes Pal 800 trunking. I'm in the Aiken/Edgefield/Saluda county area and thats what I have received them on. I'm sure they probably use other means elsewhere in the state.
Last time I looked at my pay stub it said SOUTH CAROLINA FORESTRY COMMISSION. We dont have an SC Forest Service !!!!! 4 states have Commissions. SC GA AL and MS
