Radio encryption in Williamson County
Every one of the six agencies logged in Williamson County is recorded as fully encrypted, and all of them operate on the Greater Austin/Travis Regional Radio System (GATRRS). Four use P25 DES-OFB — the City of Georgetown, City of Hutto, City of Leander and City of Taylor — while Round Rock Police and a Leander Township Police record are listed with P25 AES-256. Only the City of Leander entry has been verified; the other five records are unverified against system data. Fifteen of 17 monitored talkgroups are encrypted, leaving just two in the clear, so scanner coverage of this county is close to nonexistent in the current data. Anyone considering equipment here should confirm the live picture on RadioReference first.
