1. Listen live

Madison County radio traffic centers on Huntsville, the county seat and largest city in Alabama, extending outward to Madison, Harvest, Hazel Green, New Market, Meridianville, Gurley, Owens Cross Roads, New Hope, Triana, and Redstone Arsenal. Listeners typically hear dispatch for law enforcement and fire, plus traffic incidents along I-565, US 72, US 231, US 431, State Route 53, and Research Park Boulevard.

A few realistic expectations:

• Some channels are encrypted: Huntsville Police primary dispatch talkgroups (30525–30545) and tactical law enforcement operations are fully encrypted.
• Transmission delays: Online audio stream feeds process through hardware encoders and digital networks, introducing an audio delay of several seconds compared to real-time radio signals.
• Cross-border coverage: Madison County shares borders with Limestone, Morgan, Marshall, and Jackson counties in Alabama, as well as Lincoln and Franklin counties in Tennessee.
