Radio encryption in Winnebago County
Rockford Police, verified, and the Winnebago County Sheriff's Office, unverified, are the two agencies logged in Winnebago County, both recorded as fully encrypted using P25 ADP. Traffic runs on STARCOM21, the Illinois statewide system, and a Diga-Talk system. Four of five monitored talkgroups are encrypted with one in the clear, so almost nothing in this record remains receivable. That conclusion rests on a small talkgroup sample and one unconfirmed agency record, so treat RadioReference as the authority on current status before buying a scanner for this county.
