Hurricane Florence coming! You’ve all seen weather radios and you’ve all seen they generally cost $50 or more. On a good day you can find one for $35 or so.
The goal is to receive NOAA which transmits on the following 7 frequencies. There will be one or two specific to your area. The frequencies below are in MegaHertz (MHz).
So at this point it is safe to say I’m a police scanner junkie. This started with my love of Software Defined Radio (SDR) devices. You get an SDR then you tune to FM stereo, then you track aircraft ADSB, then somewhere along the lines you start listening to anything you can which includes emergency services stuff.
First you just listen to analog police, then you find out there are digital trunked systems. That evolves into using programs such as DSD+ with Unitrunker or another program called SDRTrunk or OP25.
Then you realize that you’re into hardware scanners. I started out with a Uniden SDS100 which is probably the most technologically advanced consumer grade scanner on the market at this moment. It probably unseated the Whistler TRX-1. If you read the forums there is kind of a Ford/Chevy thing going on with Uniden/Whistler. I had to see what all the fuss was about so I got the Whistler TRX-1.
So I bought the Uniden SDS100 hardware scanner, and I love it. But it cost $700, and then I added DMR decoding for $60, and NXDN decoding for $50. So I’m into this in a big way. The SDS100 is POWERFUL. It is not a toy by any stretch of the imagination. It comes with free control software called Sentinel (yeah the download is hard to find on that page). Sentinel is adequate for managing favorites and reading and writing to the scanner and it is all you NEED.
However I stumbled across this hunk of software called Proscan which looked interesting but it also costs $50. Where does the cost with this scanner end? Well, like most programs Proscan has a 30 day trial version so I gave it a shot. After playing with it for like an hour I knew it was worth the cost so I bought it. It does NOT disappoint.
I have a Uniden SDS100 scanner however the only software available for programming and firmware and database updates is Windows only. Sigh. I’m a Mac guy. Wineskin to the rescue. Download Wineskin and double click.
In my last part I set the Pi up to stream to Broadcastify. In this one we are just going to pump audio out through the headphone jack.
I’m doing this with an old generic black RTL-SDR and it works and it works fine but it is kind of susceptible to heat and cold and the ppm correction drifts a bit. I really recommend getting a v3 RTL-SDR or a NESDR Smart as they seem more stable. At any rate it doesn’t matter, you’ll just have to deal with the drift if you have any.
My assumption here is that you have Raspbian installed on at least a Pi 3. I haven’t tried it on a lesser Pi but I had it on a Pi 3 B + and then I found a couple Pi 3 B’s laying around and figured I’d reclaim my B+ for another project on another day. OP25 runs fine on the Pi 3.
So I finally figured out OP25 and I have this brand new Raspberry Pi 3 B + laying around doing nothing. In this segment we’ll install OP25 on Raspberry Pi and then take our police scanner feed and send it to the internet on Broadcastify.
As someone pointed out to me yesterday, “There’s an app for that” they are indeed correct. You can get Police Scanner Apps for IOS and Android. Guess where the feeds in those apps comes from? If you said Broadcastify you’d be correct. So if no one is feeding your municipality then there will be no feed in the app. We will be that feed.
So the assumption is that you have a Pi with Raspbian installed and you kind of know how to use it.
OP25 is a program that decodes P25 Phase 1 and Phase 2 digital radio. Some municipal areas are upgrading to P25 Phase 2 so almost gone are the days that you can track them with a police scanner since P25 is a Trunked Radio system and not just a lone frequency to monitor. The only things that do Phase 2 are hardware scanners and hardware radios and OP25 for software radios. Bear in mind Phase 2 could be encrypted and nothing you can do will decode it.
OP25 is HARD. I’m a geek and I messed with it on and off for a year or more and it whipped me more than once. Now that I have it working I find that it is REMARKABLY easy and I’m mad at all the geeks out there who never made a simple tutorial. There are tutorials out there, some good but everybody leaves out the good stuff or the stuff they took for granted.
So, you are a government employee AND a Linux geek. Join the club. It is possible to use your smart card to access DOD CAC Card enabled sites. A must do project for the Linux geek in you.
I’m doing this with an IOGEAR GSR202 and it will work with a lot of other CAC Card readers as well. Also I’m using Ubuntu 18.04
First of all the information is taken from this excellent website. While almost perfect there are a few minor issues that could foul a fella up. I seek to clarify those here.
First lets download the Certs for your browser. They also come from the page I have linked above (MilitaryCAC.com). Download here. Hold tight. We’ll get back to them.
DSD+ is a popular Windows digital decoding program that handles various digital protocols. I’m going to install and use it with WINE on Ununtu 18.04. The example I’ll show here today is a digital trunking control channel that the local Emergency Services uses. Without DSD+ the signal will sound like this:
No, the Bionic Beaver is not the name of Stormy Daniels new Porno………… 😀
Finally! Last night Canonical released Ubuntu version 18.04, aka, Bionic Beaver. It can be downloaded here.
18.04 is a Long Term Support (LTS) version with support for 5 years.
I installed it on only one laptop so far and all seems to be working fine. It does appear that some of the software that I used with version 16.04 isn’t all compatible yet however that will likely change in the following days.
