Dispatch460 is a real-time monitoring platform for Milford, CT Fire and EMS radio communications, capturing two channels simultaneously.
A software-defined radio (SDRplay RSPduo, dual-tuner) captures both frequencies at once. GNU Radio handles FM demodulation and squelch-gated recording. Each transmission is transcribed by a self-hosted, fine-tuned Whisper large-v3 speech-recognition model, then run through automated dispatch detection, street-name correction, and geocoding to place calls on a map — published live to the web within seconds.
On-premises capture and AI inference keep sensitive processing local, paired with a cloud-hosted web application and database.
Dispatch460 monitors publicly-broadcast radio for informational purposes and is not affiliated with the City of Milford or its emergency services.
