Listen live to Boone County public safety radio — the Sheriff, county fire, and EMS across Boone, Madrid, Ogden and the rest of the county. Streamed 24/7. Free, no app to install, no ads.
Boone County public safety runs on the Iowa Statewide Interoperable Communications System (ISICS) — a P25 Phase II trunked radio network, monitored here from the Woodward/Ames Simulcast site. A conventional analog scanner can't follow a trunked system — agencies don't sit on a fixed frequency; the network assigns channels dynamically and organizes traffic into talkgroups. NCISS decodes the trunk and streams the talkgroups as plain audio in your browser.
What sets this apart from other ways to listen to Boone County:
No ads, no pre-roll, no paywall. Talkgroup names are visible to everyone, not locked behind a subscription.
Plays in any browser on any device. No account required to listen.
Boone County encrypts a lot of its system. We show the full list — what's clear and what's sealed — instead of quietly leaving out what can't be carried.
Operated by a licensed Iowa ham radio operator in the coverage region, actively listening so the talkgroups stay accurate.
The Boone County Sheriff dispatches law enforcement, fire, and EMS for communities throughout the county on the main dispatch channel carried here — including Boone, Madrid, Ogden, Luther, Pilot Mound, and the rural areas in between. The county's fire departments dispatch on the fire channels carried on this stream as well.
Boone — the county seat, and home to Ledges State Park and the Boone & Scenic Valley Railroad — generates much of the county's public safety traffic. One stream covers the city and the surrounding county together.

Yes. Every NCISS stream is free — no ads, no pre-roll, no paywall. Open the stream and you're listening.
No. The stream plays directly in your browser. If you'd rather use a scanner app, any app that supports Icecast or HTTP audio can connect to the same stream URL.
The Boone County Sheriff dispatches law, fire, and EMS countywide on the channels carried here — covering Boone, Madrid, Ogden, Luther, Pilot Mound, and the rural areas. The county fire departments are on the fire channels carried on this stream.
Yes — Boone encrypts a significant part of its system. Law 1 (main dispatch) and the county fire/EMS channels are clear and carried here, but Law 2, the tactical incident channels, and the Jail channel are encrypted and can't be carried by anyone. We show the full system rather than hiding what can't be decoded. Boone encrypts noticeably more of its system than the neighboring counties NCISS monitors — places like Greene, Guthrie, and Webster keep the majority of their channels in the clear. That's a choice each agency makes; we simply show you what's open and what isn't, for every county we cover.
Boone County runs on the ISICS P25 Phase II trunked network, not conventional VHF. A standard analog scanner can't follow trunked talkgroups. NCISS decodes the P25 system directly and streams it in plain audio.
The stream runs 24/7 and is typically 30–60 seconds behind real time, normal for internet streaming. Not suitable for emergency response. If you need emergency services, call 911.
