What is Mobile-Trunked-Radio-Decoder?

This project delivers a complete hardware blueprint for building a mobile decoder that captures and decodes P25 Phase 1 and 2 trunked radio signals in your vehicle. It solves the pain of scanning fragmented public safety and trunked systems by pairing RTL-SDR receivers with a Raspberry Pi running op25 software, outputting talkgroups to a touchscreen display and audio via a ducker module. You get a plug-and-play BOM with Amazon links, keeping required costs under $130 for core hardware stuff like antennas and power adapters.

Why is it gaining traction?

Unlike scattered forum posts or generic SDR guides, it provides a vehicle-specific parts list with costs, notes, and suppliers—think hardware stuff list ready for ace hardware near me or hardware stuff 4u on eBay. Developers into GitHub hardware acceleration or hardware in the loop setups dig the modular cabling for clean installs, plus integration with op25 for real-time decoding without custom scripting. The pre-built BOM in progress hints at easier replication.

Who should use this?

Ham radio operators mounting scanners in cars, public safety monitors chasing trunked traffic on the go, or SDR tinkerers testing GitHub hardware test rigs with RTL-SDR. Ideal for those sourcing hardware stuff images or hardware info from stores, not coders needing software polish.

Verdict

Skip unless you're prototyping radio hardware—1.0% credibility score, 19 stars, and just a README with BOM scream early-stage experiment, lacking code, tests, or docs. Solid hardware stuff meaning for DIYers, but verify op25 compatibility yourself before buying.
