Default Raspberry PI as a P25 Scanner

I am putting this here because a lot of cities and counties are switching over to P25 and thought this would be a less expensive alternative to an actual digital scanner that I cannot afford. I saw a post on another website from a person who has a Raspberry PI setup as a P25 scanner. The problem is that he did not go into any detail as to what other equipment he is using or how it is setup. I am curious if this is even possible and if so what other equipment is needed. Has anyone done this that can give me some insight on how to make this work?


Thank you,

73

Ras-Pi may be cheaper, but the set up is involved.

Try OP25..Google that and Raspberry pi,
use the Pi, B3+ it will involve loading the rtlsdr
drivers..ect...

getting the pieces to play nice is the big dilemma..
linux is easy, but the learning curve is harsh.

then you have the option use with a monitor on your desktop,
or fit a TFT on it to allow use on the go.
Also, if carrying around the Pi...you will need to set up a power bank,

Cheaper, Yea..not by much..ras-pi may be 100..150 to set up well.
p25 capable hand held,,200..250...

.... and since it wasn't listed specifically in fourthhorseman's reply, you'll also need to buy an RTL-SDR USB receiver stick, which plugs into the RasPi USB. The RasPi itself has no radio receiver components.
