Map Grids

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 represents one of the four 1/4 mile by 1/4 mile subgrids within a primary grid.

Technical Information

Feed Device: Raspberry Pi 3 Model B+
Receiver: RTL-SDR Blog v3
Software: OP25 (boatbod), Liquidsoap

Radio System: Aurora


This is a demonstration feed testing the features and cost effectiveness of a Pi + SDR + OP25 combination over a regular scanner. Aurora's radio system is a P25 Phase 2 four site simulcast radio system. These systems are notorious for being difficult to monitor on all scanners designed prior to 2018 without some type of special directional antenna setup. Reception is not always guarenteed even with such a setup and sometimes requires luck. Currently only a very limited selection of full feature top of the line scanners costing between $649.99 to $699.99 will reliably receive these systems.

The full cost of this setup is the following.
$34.99 - Raspberry Pi 3 Model 3B+
$9.99 - 5V 2.5A Power Supply
$2.99 - 16GB microSD card
$34.95 - RTL-SDR Blog with Antenna Kit
Total: $82.92

This is a fraction of the $649.99 to $699.99 price tag. For the price of one of these scanners, someone could setup seven standalone feeds (1x Raspberry Pi and 1x RTL-SDR) and upto 10-12 feeds when providing two to three feeds per Raspberry Pi.

The setup is located approximately 9 miles from the nearest site and uses the stock RTL-SDR Blog v3 dipole antenna kit to achieve its current performance.
