9a6
9A6 is a Campbellton unit...
9 being "District 9" (St. Quentin through Bathurst, Including Campbellton)
"A" being "General Duties Car"
6 being unit #6 (Units 1-15 are stationed in Campbellton, Units 50 - 59 are stationed in Dalhousie)
Generally they don't tend to go too far from their home detachment & repeater(s)
They aren't like the ambulance system where the ambulances are shifted around the province on a daily basis. RCMP cars usually stay in their home town, and it's pretty rare for them to go outside of their district.
Just curious, what repeaters are you catching?
