Jim is correct, Arapahoe County Sheriff dispatches for Deer Trail and Byers. Deer Trail is very unique because they don't receive tones. ACSO initiates a party-line telephone call to all of the volunteers who will pick up the phone and advise of their availability. Once they respond to the call they'll usually stay on ACSO 1, Talkgroup 3001. Occasionally they'll be on Talkgroup 3071 & 3072.
