Radio encryption in Harris County
Harris County is a patchwork rather than a blackout: of the 159 talkgroups catalogued across its systems, 135 are still in the clear and 18 carry encryption. Eleven of the twenty-nine listed agencies encrypt everything — Bellaire, Humble, La Porte and Seabrook among them — while eighteen encrypt selectively, with the City of Houston, Deer Park and Webster locking down tactical channels on the Texas Wide Area Radio Network (TxWARN). Fifteen of those agency records are still unverified, so a reporter should confirm any single department's current status on RadioReference before relying on it.
