OpenSky is encrypted and was also used as the Pennsylvania Statewide Radio Network from 2003-2022. As of 2017, the Pennsylvania Statewide Radio Network is working on migrating to APCO-25 Phase 2 (P25 Phase 2), with most, if not all, the law enforcement agencies having full encryption enabled.
As of 2026, there are few towers actively transmitting OpenSky.
