Almost twenty years now since the digital start to invade radios. I sold everything when I couldn’t listen much any more. I had software with black box, optoelectronics high tech frequency counter that auto synchronized my Acom high tech scanner end few other things. I gave up and been told that is impossible to get digital listening scanners at the time. Some told me that each communication company had their own software to decode it. It was the good old time when we could listen police, fire station, ambulance, companies, FRS, wireless home phones, cell phones and few more. I miss all that.
@@n8mail76 suret but 20 years ago, we could not get the digital communication. Scanners were not out yet. I don’t believe that you could have listen Montreal police radio when they switch from analogue to digital in the 2000’. I don’t have this hobby anymore, so I’m not going to start buying again.
Phil - Don't be intimidated. If I can do it, trust me, anyone can! Look at it like a bunch of small easy steps all strung together to make a big project. It's worth it though. My dad was a Ham and an EE and unfortunately, I never understood has passion for radio technology until after he was gone. Now, I'm obsessed with it. Wish he could have experienced SDR! Good luck to you!
Cool! One day, I got noise instead of audio from my analog scanner while trying to listen to Police frequencies around my neighborhood. I later found out they changed into trunking and then I got this Uniden Bearcat trunking scanner only to find out that it only received analog trunking. I'm looking forward to watching your tutoring series and learn how to decode digital trunking. I happen to have two sdr receivers: an SDRplay RSP2 and an Airspy HF+ Discovery (recently acquired and not yet fully tested).
Thanks for doing these videos. I followed your instructions to the "T" and everything worked. I still can't get SDR# to work with DSD+ but the Unitrunker works great. The only thing is there has to be a way to save the fixed control frequencies that are around me in Unitrunker somehow.
glad it worked. i really have to go back through this process and recreate the videos. seems like people are having trouble as things change. in a perfect world, i would do it right away, but my world is far from perfect.
Steve's 5 C's Yes I agree with you on having to redo them as Linux is constantly changing and these developers are constantly updating stuff. I tried the Linux after doing the prerequisites from your raspberry pi video and after I installed ant i got the loop. I swapped the hard drive and am loading 7 on that one now. I tried 8.1 and 10 with unitrunker and had few problems but I can't get dsd+ to work with sdr#. It should use the same principles but it's driving me nuts! I talked before about Fusion DMR and it looks like dsd+ will decode Yaesu System Fusion packets. People are buying expensive radios to listen to this type of digital modulation. I like $25 SDR setups.
Now what I need to come up with is a simple program that will allow this to work on a Raspberry Pi. One single frequency and give me an active low or high output on the IO pins when either a single privat NAC code or an all call NAC CODE is received. Basically a control for a simple P25 repeater. The repeater can pass the data transparently to the receivers, just need to protect repeater from analogue ker-chunkers.
(BTW, I've been linking the heck out of your video set, it's one of the most informative tutorials on how to get this stuff working. OUTSTANDING work!)
Steve! GREAT set of videos! Thing is, though, it doesn't take in to account that there are systems that Unitrunker WON'T decode, including DMR. Have you had a chance to figure out how to monitor those yet?
I have the same scanner as you show here, that old scanner can still be used, as I have modified it with a discriminator output, and used it for decoding the AIS signal on the PC running Shipplotter.
I would need two RTL dongles to listen to local trunking channels? I really enjoy your videos. I am following them to a T. Hope to get things up and working with all your suggestions.Thanks for explanations of all related software. You make it sound so easy. Cheers!! Wish me happy listening.. :)
Thanks for the video! I am going to be setting up a discone on my rooftop later on when I get everything together to finish it. Can I use one antenna and a cable splitter, or do I need two antennas?
Very nice tutorial. I have a question though. Is there a way to control the scanner once you're locked in? I.e., can I hold on a talkgroup? Is there another program that acts like a virtual controller to tag the TGIDs with their names? I like the setup but as an open searching scanner...you'd hear everything on the system including the trash pickup guys. I'd imagine in Charlotte that'd be quite annoying. I'm currently using using a Unidentifiable 396xt as my portable and a new 352 as my home unit. I joke to use Freescan for programming logging and Procom96 for deep logging. I'm monitoring in the Triad area around Greensboro, Thomasville and High Point mostly. Thanks!
Question. I just watched Tahoe staves on how to do a radio scanner on the computer digital and the trunking service it's from 2017 is all that information still good. I'm not really good with computers so it looked very intimidating to me.
you can use ether unitrunker 2 by its self or sdr trunk no need for dsd+ anymore they can decode voice on their own sdr trunk is the best in my opinion tho
@Steve's 5 C's Hello! I am totally new to this and my local public services has also switched to digital. I don't have $100+ to throw around just to listen to the pd, fmd, and ems. I came across this video! I see in the description other videos. Are they assigned as step by step videos? Also, is there a way I can get this to work in my vehicle? Perhaps just bring my whole laptop into the car LOL.?
Hello, I live in brown county Wisconsin. I checked radio references for my county control channel and noticed that public safety operates in the 770. Band. However, I noticed that they are in the 800mhz bands. Not sure how that is possible?
The main problem isn't money. To encrypt transmissions requires key management which is itself a challenge. For example, neighboring municipalities would need the same key to assist with mutual aid. (A separate unencrypted mutual aid channel is really unhelpful as all the important traffic is taking place on the normal encrypted channel.) But once enough people know a "secret" it ceases to be a secret and you are back to smart guys like Steve adding an AES-256 decryption app to the mix and typing in the key. The good-practice of changing a key every 3 months becomes a nightmare.
Hello Steve, great vids, one question please, does the software Unitracker tell the second RTLSDR (the scan not the fixed) where to jump to for the channels?, cause both the Fixed and scan are set to the same Audio cable....its just confusing a bit for my slow brain, whats telling the other RTLSDR (scan) to jump ? cheers
I have been looking at scanners, but like you said Steve, they are crazy priced($450-500)....does this software & SDR work on P25 2 systems? Do they make any of this software for Android(tablets) or does it need to be on windows? I look forward to watching you vids & learning how this all works & I truly Thank You for sharing your knowledge!!
Hi Steve: Great videos. I have 2 RTL2832U dongles, Unitrunker Version 1.0.3.2.7, Virtual Cable, Windows 10 on a Core I7 PC. I have been able to get the first dongle to receive the control channel for a local Motorola Type II system and everything seems to be working great. However, I cannot get the second dongle to open no matter what I do. Any help would really be appreciated. Thanks, John
Thank you for the video. What do you mean about encrypted transmittion? I knew that trunk system meaning that both operators change continually frequency and that is why is difficult to hear the police or other security services. It is that what you call encrypted?
Digital transmissions need to be encoded to translate the digital message into words we can understand. If digital is unencrypted, it can be decoded and understood. If it is encrypted, even DSD+ won't help.
Encoding is a scheme for various means of transmitting a signal to improve it's transmission and reception, (i.e. enhance bandwidth). Encryption (validate in webster for a good definition) is a method of hiding a message for privacy or secrecy. According to FCC rules you may decode and listen to an encoded traffic on the airwaves (minus cell and cordless phone frequencies). You may not legaly un-encrypt an encrypted transmission. The FCC rules are posted on their web-page, read the legalese to get a better understanding.
Awesome video series Steve! I watched and bookmarked all 5. I just dropped over $250 for a Uniden BCD325P2 scanner that I am live feeding to Radio Reference. But not disappointed tho because with your videos when I get SDR running on my PC I can use it to live feed RR and free up the new portable I bought. Very interested in the Raspberry Pi set up too! Again thanks for making these videos! 73, KE0EYH
@Jimmie - It's comments like yours that make all the hours of content generation worth while, thanks! I just looked into the Raspberry Pi setup. Looks like a no go for SDR# so far, but I'll continue to investigate Unitrunker and the others.
I currently have one SDR and didn't know I needed 2 for Unitrunking so thanks for the clarity but I'm a little confused on the connections to the laptop. Were you using an external USB on your laptop?
so i need 2 of those sdr's to listen to p25 phase I ?? My main goal is to make a portable raspberry pi police scanner for the South Carolina Columbia area
HI I NEED YOUR HELP i have set up my RTLSDR dongle as you say to do and it is work but i have one problem the voice is clear on to receive but after 10minutes it cuts out and i can't understand any thing it songs all GARGLE and i cant understand anything CAN YOU LPEASE TELL ME WHAT TO DO TO FIX IT THANKS
Thanks for the reply. I have followed your instructions and can now pickup some transmissions from phase 1. I have tried to follow other videos and have had no luck. You have made it very clear. Thanks.
My area (Onondaga County, NY) is listed as P25 Phase II but with one RTL-SDR (same as in the video) I can listen to our 5 county consortium. New York State Police are listed as Phase I but I never hear them on 700MHz but I hear Sheriff's Deputies, City Police and Municipal police + EMS/Fire on 450MHz and 150MHz. I bought two just in case, am I missing out on something with only one SDR? I'm using SDRF, DSD+, etc.
As for a Linux series of os/applications try using dragon/os focal. It uses a Linux os coupled to a great many programs already trimmed out. I personally use it on a thumb drive as a bootable and run much of my ads-b and navigation applications from its front end. Try sdr-angel, I can recommend it wholeheartedly.
FYI everyone: DSDplus did not contain Zadig. You can download it at zadig.akeo.ie/ I am waiting for my second RTL to arrive from Amazon before I continue the installation. Wondering if this will work on P25 phase 2.
It will work with one sdr but on a larger system you will need at least two sdr's to cover the systems bandwidth, With just one you will be missing calls on a larger system.
i am running windows10 64bit i have tried installing and uninstall five times when i hit play i get nothing no sound or waterfall can it be the vb cable because it says download for Windows 7 HELP HELP HELP going nuts over this
This system can not decrypt any encrypted p25 or sky link.it can only pick up none encrypted phase 1 or 2 p25 sytems or any none encrypted radio waves.no has ever have been documented on dycrypting any encrypted didtil systems.
Who would know of the European digital police radio systems and how to hack in and listen in to them today? who is an authority on the digital radio system RAKEL is a system based on a digital standard TETRA "Terrestrial Trunked Radio" which is used within the EU for "blue light systems". The frequency band is 380 to 395 MHz. anyone that know about this and who on TH-cam that is great authority on educating in this system? please let me know, is my passion to understand radio networks and smart phone hacking. Am not a criminal, but is passion about this tech and like to learn and understand. thanks!

Yes, not mandatory, but definitetly helps because the USB ports on my LT are so close together.
Hey , great video. But isnt there enough bandwidth to do all of it with 1 SDR? Why use 2?
depends on your area and what you are listening to
Update: Can I get a link to just the cords that go on the end of the RTL? with antennas?
i think you are referring to my 4 in 1 usb. if so, here: amzn.to/2KpfrOx

Can you transmit on a sdr
Not these. You can transmit RX freq on a HackRf
Do you have any software/instructions to allow P25 Phase 2?
use sdr trunk
What if I have a Mac computer? Will what you are showing work on an Apple Mac computer?
I'm sorry but I have absolutely zero experience with Macs. Hopefully someone else will chime in.
Sell the Mac and buy a proper computer.

Who would know of the European digital police radio systems and how to hack in and listen in to them today? who is an authority on the digital radio system RAKEL is a system based on a digital standard TETRA "Terrestrial Trunked Radio" which is used within the EU for "blue light systems". The frequency band is 380 to 395 MHz.
anyone that know about this and who on TH-cam that is great authority on educating in this system?
please let me know, is my passion to understand radio networks and smart phone hacking. Am not a criminal, but is passion about this tech and like to learn and understand.
thanks!
Thats Not True That You Can`t Hear Anything In Analog, In My Country Even POLICE Use Analog WITHOUT Encrypting So I Just Listen To The Cops With My HT UV9R Plus , But Video Is Really Good, Good Info, I Will Try The Sdr Now. :)
I was not trying to be literal in the video. In the U.S. you can still get analog, but it's usually bus drivers, garbage trucks, dispatch stuff. Emergency stuff all seems to be digital
@@TahoeSteve In USA I Believe, Yes, But Sill, When Im Checking Out USA LA Radios, Its Like, WOOWO, Like Gazzilion Stations And Amateur Frequencies Pop Up. In My Country There are ONLY Like 50 Hams :D
and i was gonna spend $350 on a uniden scanner. god.
