Monitor Fire/Police Radio
Interested in being able to monitor Fire/Police radio channels on the new P25 Phase 2 radio system? We have identified a cost effective way to accomplish this using a Raspberry Pi 3 Model 3+ Linux computer system, with a RTL-SDR software defined radio receiver and a very simple internal antenna. The total cost for these components should be approximately $100.00. The needed items can be purchased via the Internet (Amazon Prime). Once you have purchased the items listed in the package below, we can assist you in programming the micro SD memory card, used by the Raspberry Pi. The configuration will allow you to monitor any unencrypted Police/Fire radio channel operating on the Plano PAWM (Plano, Allen, Wiley, Murphy) radio system you may be interested in.
We have assembled a recommended parts list for your convenience. All of the items can be purchased on Amazon so if you have a Prime membership, you can be up and running in less than a week.
