Three live audio feeds stream 24/7 to Broadcastify. Click any feed to start listening — no app required.
Search the past 7 days of every monitored talkgroup across all five P25 sites — about 75,000 calls captured per day. Filter by talkgroup, agency, system, or tag. Replay any call.
If you've never used rdio-scanner before, here's how to get the most out of it.
This is a personal amateur radio project run by KI4GIP from Houston, Texas. An array of RTL-SDR and AirSpy receivers — collectively called "the Beast" — demodulate P25 Phase II trunked traffic from five sites across the Digital TXWARN trunking system covering Harris County and the City of Houston.
The Broadcastify feeds above are the public-facing curated streams. The full archive viewer is provided for personal use and research — talkgroup browsing, search, and replay of past calls.
Most scanner streams sound rough because they pipe trunk-recorder output straight to the listener. This one runs a multi-stage pipeline — recording, DSP, talkgroup filtering, metadata enrichment, and a watchdog process that catches silent failure modes most feeds miss.
trunk-recorder writes each captured transmission to disk as soon as it ends.inotify watcher fires sox on every new file: high-pass at 300 Hz, low-pass at 3 kHz, peak normalize to −3 dB, silence trim on both ends. Loud and quiet calls land at consistent levels.HPD-3 NORTH PATROL scroll on their phone instead of a numeric ID.ezstream serves newest-first from the whitelisted pool. sox-generated silence fills brief gaps so the live stream stays continuously connected to the Broadcastify mount and never times out.Use the form below for site questions, feed coverage feedback, or general inquiries about the project.
