Heard a 10-27,28,29 check on the Windsor Public Safety 800mhz system using an ID of 'Unit 199". Turned out to be CP Rail Police, drove up on them with the vehicle stopped near the CP tracks.
Has "Unit 199" been linked to one Talkgroup or LID? could it be "anyone" linking in on 142.7700mhz that is patched onto the system???
Seam to have numerous reliable reports of both CP Police and UWO police using this call sign on the Cities system. Just puting forth one possible solution.
