Thanks, Living in BC here, we see quite a few Low Band UHF repeaters. RCMP, Forestry, Highways, to name a few, used low band UHF as link frequencies, so when a hub repeater went up it was low band. These have come out of service now, because of narrow banding, and its just a matter if figuring out if they'll work in the ham band.
