Forestry
I don't monitor V.I.P.E.R. that often, I am a searcher. But here is what I have picked up in Ashevegas over time, confirmed. hope it helps a little.
51991 N.C. FORESTRY SERVICE
52109 WRC FAR WEST DIST 9 091618
52110 WRC FAR WEST DIST 9 COMMON
60643 U.S. FORESTRY SERVICE OPS 1
N.C. State Forest.. 151.175 N.C. Forest Service mobile relay, WQEU844 is cancelled.
151.265 Arboretum in Asheville WPTK645, probably additional freqs on the license
151.445 Statewide Mobile WPGM564
151.475 Statewide repeater WQCA321
These are all last received as of 08/13/18. There are others on the list, but I have searching to do, have fun, take care.
The three listed current licenses I believe contain multiple frequencies, if I remember right. I just don't have them built into a system yet.
