Radio encryption in San Diego County
Every agency record for San Diego County in this dataset is verified against RadioReference system data, with no unverified entries. Seven police agencies are tracked, all on P25 AES-256: Chula Vista, El Cajon, Escondido, La Mesa, Oceanside, and San Diego Harbour police encrypt everything monitored, while San Diego Police is logged as encrypting tactical channels. The county spans an unusually broad set of systems, including San Diego-Imperial County RCS NextGen, San Diego City 800MHz and 700 MHz, US Marine Corps Installations West (MCI-West), a Department of Defense (14C) system, Mobile Relay Associates Diga-Talk, Fisher Wireless TeamTalk, and the San Diego Zoo. Of 312 catalogued talkgroups, 46 are encrypted and 265 stay in the clear, so a scanner still receives a large share of monitored traffic.
