Radio encryption in Douglas County
Every agency recorded in Douglas County, Colorado uses P25 ADP on the State of Colorado DTRS. Castle Rock, Lone Tree and Parker police encrypt all monitored channels and are verified against RadioReference; the Douglas County Sheriff's Office is listed as encrypting tactical channels and that record is unverified. The talkgroup split is nearly even, with 12 of the 26 tracked talkgroups in the clear and 14 encrypted, so roughly half of what the county puts on the air in this dataset is receivable. That makes Douglas County a marginal case for a scanner buyer: worth checking the live DTRS talkgroup list for the specific municipalities you care about before deciding.
