Great vid mate, well done. Just a reminder folks, this will do trunking but not decrypt secured channels, so for us in Australia, you will not hear the police.
-
Now this is slick! I may have to do this! Great video!

Very nice. I just received my first pi5 a couple of days ago and was looking for a project. Even though I'm in a rural area, the next county over has a trunked system. This should be perfect, and I only need to buy a new power supply for the pi5. I already have several rtl dongles and a discone antenna.
-
I’m going to try this one, I have only heard of people getting trunked signals using 2 dongles. This is great news! Thanks!
-
I use a cellular router antenna with my rtl sdr blog v3 and it picks up the p25 system very well
-
I have a sdr kit I believe I'm going to try this

How is your pi5 holding up with sdrt? Have you considered ading a second sdr dongle to handle the bandwidth of your metro p25? In my case pi5 was just not enough to stay stable running sdrt with 2x rtlsdr's in sacramento. The cpu remains very close to pegged like yours, and this resulted in way too much dropped traffic. I reverted back to using an old x86 laptop for now.

You have my undivided attention. I've been contemplating making something like this for a while and your video gets me motivated. I would love to use a smaller display to match the foot print of the Rasp Pi. Is that a touchscreen with USB cable back to the Pi? or does that pop up go away on its own as the software loads right before you hear the dispatcher talking?

hola pregunta este sofware sirve ´para usarlo en una pc con windows 7

Lol I was reading the RTL-SDR blog after ordering one to read my meters, and stumbled across this video! Just so happens we have the same keyboard! Great minds think alike I guess

Hello, Great video. I was wondering however if there are any projects similar to this one that employ an RTOS instead of using a full Debian based os? I imagine that unless the bottleneck is the CPU based decryption, this could allow for a rpi4 to be able to handle the efforts. This is way outside of my technical knowledge but i like to learn so if anyone has ideas i would be happy to brain storm!

I bought a uniden bcd436hp for 100 and sold it for 300 ! But yea I use sdr trunk to hear what's going on or my EF Johnson 5100es

Hello. I have a question about your setup
-
hey what kind of monitor/tablet do u have there?
-
How much RAM does this require? I assume you would need the Pi5 with 8gb to run this?
-
Does this setup require wifi (after the initial setup)? Or can it run in ‘the field’ just off of the radio frequencies? It looks perfect for part of an emergency comms setup.
-
Does the Hackrfone have the capability of decoding p25? Instead of the RTL you have there?
-
Do you have a write up to run it in headless mode?
-
At this point though, why not just buy a dedicated tablet and running a radio scanner app?
-
Could you give us a hardware list? What are you using for the screen , etc?
