I've been playing with radio poo poo for a long time but never posted it in the 'pos.

Roughly a year ago I set up a bunch of RTL-SDRs to be a full time scanner for the trunked radio systems of my county and a few surrounding counties. Fortunately they haven't gone encrypted (mostly) as has been the trend. I'm no fan of the cops so its nice to be able to more or less openly listen to what they're up to, though I spend most of my time listening to the fire dept.




Four SDRs plugged into a mini PC outside in a cabinet where the antennas are to reduce the coax run.
Combined with a brilliant piece of software called SDR Trunk (https://github.com/DSheirer/sdrtrunk) I can receive all the traffic on the local trunked systems.



It has been pulling just about 100% of every single transmission over these systems for about a year now.
