Okay I know the old system was on VHF but are the firefighters Transmiting on VHF Repeaters or the UHF Repeaters. I'd assume there transmiting on the UHF since they always use their UHF fireground 486.1125 frequency. the last time I looked at a Firefighters belt i saw some kind of motorola xts series porable radio. can any one confirmed this? and confirme if they're transmiting on the UHF repeaters?
