In plain words

Super Trunking Scanner is an archived software-defined radio project that monitored Santa Clara County emergency communications from 2011 to 2016. The site contains a historical audio archive of police, fire, and multi-agency radio transmissions spanning several years. While no longer actively recording, visitors can listen to the recorded calls and learn about how software-defined radio technology enabled the monitoring system to function. The project is primarily of interest to radio enthusiasts and those curious about emergency services communications.
