Been watching this show on Discovery this season, showcasing Lesser Slave River Fire Service and Yellowhead County Fire Rescue. I'm impressed that both agencies use the exact same tone to alert their halls (which is tone A of my department's tones - my blood pressure hates that), and have MDC1200 plus FRS roger beeps on what seem to be both VHF analog and DMR per the radios shown and heard. Actually I remember at least one AFRRCS radio in an early episode too. I guess plain old comms without squawks and beeps isn't sexy enough for TV.
