Hacking the TV tuner and making DIY antena to recieve weather images from satellites (NOAA)

Hi everybody this time I want to show You something which is pretty cool and super easy to make i want to show You how to recieve real photos from a weather satellites only using your computer, televison tuner and handmade antena so we will try to pick the signal form NOAA satellites which fly more than 800 km above the earth and this is amazing when You think about it those satellites are making the pictures in infrared of earth and then th epictures are send to earth using standard FM frequencies and You can pick the signal using an antena inf fact you will need not only an antena but also sdr device. it is Software Defined Radio device fortunately it turns that ordinary television tuner which You an buy for almost no money it is a very good sdr device so you will need one of this to recieve the signal antena in fact could be very simple this is just two copper wires conected under 120 degrees and then connected to typical television cable as You can see I;m making it with my son and it is very easy to make we are using wery thin copper wire and we are using plywood as the holder for the wires the whole project of recieving the images from the satellites it was the idea of my son i think that it was because of some cartoons he was watching one important thing considering an anthena you have to put it somewhere where there are no eletronic noises i recommend the open field or something like this now the software i recommend You to use the wxtoimg this is the program which allows You to track the weather satellites and to decode signal from them this program is available for all operating systems so just go to their site and get this program first thing You have to make in satellite tracking software is to set Your grand station on eartha i'm showing You how to do that now after You set Your ground station you have to update the kepplers as I'm doing it now on the screen and now we are ready to predict what satelilite and when it will be on Your sky as You can seenot only information about the satellites but also about the frequencies which You have to listen to recieve the images from them. You have to have one more softwar ewhich allows You to recieve the signal and control Your television tuner and if You are using the windows, I recommend You to download the SDRSharp but if You are using the linux or mac os I recommend You to download gqrx in fact it doesn't metter what You chosed because those softwares are working in exact same way now the short tutorial first You have to set the frequency of the satellite, than You have to set the reciever parameters as I showed You on the screen and then You will able to see the signal on the waterfall diagram so the last thing You have to do it;s just recieve the signal and record it to the wav file on to Your system I have to admit that recieving the signal was pretty exciting not only just for my son but also for me it is really cool thing to recieve the signal from the satellite which is so high above You and to recieve the images of Your area in the real time ok after You recieve the signal You have to change it a little bit and I'm using audacity software You have to open the file and change it's frequency and save it and that's all now we are ready to decode the signal to do that open the WXTOIMG open the audio file aaand viola you have Your real time images from the satellite as I sad it was really simple now You cna play a little for example You can change the type of the images to see for example the temperatures on earth and You can correct the images change it's contrast etc in the next few days we've got several images the satellite some of them are a bit noisy but You have to be aware that we are not using any amplifiers to boost the signal so it's pretty ok as i said on the biginning, this is the simplest configuration which allows You recieve the images from satellites, but You have to be aware that only with this You are able to do much more for example You can read images from meteor satellites with better quality you can also recieve messages from International Space Station and You can listen to the typical radio transmisions which was also pretty cool for my son and he spent a many many hours sitting and searching the frequencies to recieve some transmissions and that's all thanks for watching and if You enjoyed You can subscribe my channel, bye

This is actually really useful. Saw the whole thing. The antenna design, the SDR set up and the image decoding is really useful. You can do all kind of real time land studies without needing a drone.

I bought an SDR just for this and it arrived yesterday. Today i have a satellite pass at 18:44 hopefully i can use the standard V dipole antenna!

I feel like you can really tell the dude making the vid is a good father.

wow this is actually pretty cool! I thought these dvbt devices were only for TV

[u/Bubba-Huba]

Some one show Eddie bravo this

The reason i am here is to learn useful talents, this sub never fails me

[u/awesomefacepalm]

Plan to do this one day. Because its cool as frig

[u/Code_Monkey_69]

This is cool as heck. I'm just wondering how legal this is?
