Radio encryption in Yuma County
Yuma County splits between encryption types: five agencies use P25 AES-256 and two use P25 ADP. Yuma City Police and the Yuma County Sheriff's Office encrypt all monitored channels with AES-256, as do Tacna Fire and Welton Fire; Yuma City Fire encrypts only tactical traffic, using ADP, and Rural Metro Fire/EMS encrypts everything with ADP. Two of the seven records, the Welton Fire and Yuma Township Police entries, are unverified. Three systems are listed for the county: the Arizona Wireless Integrated Network System (AZ WINS), Fisher Wireless TeamTalk and US Marine Corps Installations West. The talkgroup catalogue is close to evenly divided, with 51 of 109 encrypted and 50 in the clear, so a scanner still covers roughly half of what is monitored.
