Curious about how Aurora's map grids work? Check out this fire station map: link. Each map grid is 1/2 mile by 1/2 mile. The first number represents the north to south grid, the letter indicates the east to west grid, and the end number is represents one of the four 1/4 mile by 1/4 mile subgrids within a primary grid.
This is an experimental demonstration feed testing the features and cost effectiveness of a Pi + SDR + OP25 combination over a regular scanner. The full cost of this setup is $74, a small fraction of the cost of a full feature top of the line scanner needed to reliably monitor these types of system.
Aurora's radio system is a P25 Phase 2 four site simulcast radio system. These systems are notorious for being difficult to monitor on most traditional scanners without some type of special directional antenna setup, and reception is not always guarenteed even with such a setup. A lot of times it depends on luck. This feed is approximately 15 miles from the nearest site and does not use any special antenna setup or radio to achieve its current performance.
