Scanning the air with a NooElec NESDR Smart Bundle!

welcome to another video this is the NES dr smart bundle which is our first try at software-defined radio what is software-defined radio it's a little chip that handles all the radio reception and lets the software do the rest it came with all these antennas I hooked up a short USB extender so that they work it'll plug right in the PC but you really don't want to flex the connectors we're gonna show what you can do with this so we have no previous antenna theory or radio experience of any kind we are just seven things you can do with it in the past week or two and just with just the basic equipment one of the easiest things you can do is receive FM radio and you can see here there's three different radio stations you can scroll around by moving the mouse or you can just click on it this station is a little bit weaker than the one on the left but you can see at the bottom that thing is called the waterfall display I guess because it looks like a waterfall and the top or the you know single click on here now if you noticed up at the top you can see data is starting to fill in and that's that radio RDS data that usually has the title and artist little display in the car or whatever just like a lobe and yeah there's lots of controls you could do a lot of cool things with this you could save that RDS data out to a text file so you could record all your radio all day and then go back through the text file and look and see what songs are played when I guess [Music] now here we pulled out the CB radio to give it a try you can see the entire CB with 10 for break a breaker on the ground 50 feet in front of us and as I turn this knob here it'll change what frequency we're transmitting on so it's sort of a cool visual scan or inspectors it's just transmitting through the radio but this this sort of reminds me that that movie contact where you're kind of visually seeing a signal and analyze it a signal it's really fascinating it really makes me think differently about radio and the physics are busy right now please call later now this is FRS radio we just looked up on Wikipedia and found the frequency FRS is family radio system that's like these little Motorola walkie-talkies and you know things that people use on construction sites and just traveling in the car testing one two three this is digital data everything else that we've seen up to this point is analog this is a digital transmission called a p25 scanner and there's actually an external app called ESD Plus which comes with its own little tuner which is a little bit more basic than the SDR sharp but it also has all these windows open and up there's the frequency window it has a scanner now saying that she's diagnosed bipolar and hearing loss mr. Frank and not on her yeah we heard a lot of interesting stuff there well one really a shootout just shot one armed with yeah we this may not be the most a family friendly thing here son check the area aside for 28 burns the avenue were still getting calls inning of the 23 shots been fired still no suspect information this was interesting too it gives you all a little bit of day that comes along any of these sounds just tell your children the Carpenters fear safer hey that's 2003 Murphy breathe responses around is blessing we refer to ejaculate pant like 10 minutes ago go diagnosis but she does have brain trauma running unencrypted by the way it just sounds like a bunch of bleeps and bloops and you can see like that you can see these transmissions coming in at the bottom there you can see the like the thicker ones right right there there's a there's a some sort of police transmission but you can't decode it it is supposed to be integrated with STR sharp but but not really couldn't get that working very easily this this D SD + + f MP seems to work pretty well and it has scanning functionality it was pretty easy to get going alright the next thing we did was weather station data using a little program called RTL 433 you can see this is an old LL Bean weather sensor and it transmits on 433 megahertz and let's say see there it flashed and if you look at it here you can actually hear it coming across there it sounds like bleep [Music] that's just a bunch of sounds and so there's a little program that translates that into into actual data and it can handle a lot of different types of 433 megahertz data it can detect a lot of remote controls and sensors and things you can see here next thing we did was try to decode HD radio with with a program called NRS c5 here we go with that so HD radio is really you can see here it's a signal to the side of the main FM signal that gives you some audio signal that sounds a little bit better in the car it shows up with this little HD symbol and you have actually sub channels which is interesting so in addition to the main radio signal they can broadcast a slightly lower bitrate lower signal you it was nice to be able to get HD radio inside the house since I don't have another way to do that and it you can record it to file interesting to on this 104.5 station the main station shows you the DJ playing and the other station actually shows you the entitlement artists which I thought was unusual [Music] Ryan commercial-free around 104.5 HD tip The Love Train [Music] that's got let's see if there's another station and finally the moment the most surprising thing about this whole experiment was retrieving pager data pager a pager is it was like a one-way communications device I didn't think anybody used them anymore but apparently they're using them and sticking a lot of confidential or maybe not confidential personal information out there in the clear but you can see here on the waterfall display those signals are coming across I use a different program called PDW version 3.2 oh one so what you do is you pipe the output of SDR sharp or air spy over to this and then just is like a data dump you can see some HTML in there we have a lot of interesting stuff it looks like mostly medical stuff you know doctor information I looked up some of these numbers and domains we're seeing stuff from all over which is interesting it's also interesting it looks like a lot of people just dump their emails in this painting system so a lot of stuff from a defense contractor without servers being loaded and some weird stuff there's patient ready for x-ray surgery yeah there's a lot of interesting stuff that was probably the most surprising thing about this whole experiment was the fact that all this data was just out there and to clear unencrypted you know what a firewall is yeah it protects the other side of like so it's not being hacked that's great that well it's that hey where'd you learn that anyway anyway so that was about it so where do we go next I mean this is really just about a week of playing around with this system so our hey are certain ham transmissions you can buy adapters for that but I think probably what we'll do next is might be get a bigger antenna this is not a standard coax connector so I can't just connect another antenna to it but I guess just as a gift review if you're thinking of getting this for you know somebody it does require a little bit of time to setup we probably spent how long would you say we spent on it a couple of hours yeah maybe an hour a day over two or three days we've helped anyway yeah see you next time over and out
