I can totally see the fascination with satellites. In an unexperienced person's eyes, it looks like literal magic, being able to send/receive images from seemingly nothing.
We’ve always associated radio with sound, not pictures. So the idea of getting images through a radio would seem like magic. But images through radio is nothing new, amateur radio have been using SSTV (sending images) for ages.
When I played with this a few years ago (downloaded Meteor M2 images), all I used was a small "August DTA240" hdtv antenna with TV "rabbit ears" connected to it. I did not move the antenna(s) to track the satellite, it just sat there stationary. I also was receiving the signal indoors lol. Lots of errors in the image, but it was mostly "proof-of-concept", just to see if I could get an image. I did!! I was actually surprised it worked as well as it did. But the images that Gabe received are just stunning. COOL BEANS!!
I'm putting together a list of projects for new members in my radio club. Stuff like this is exactly the kind of thing I'm looking for. Thanks for the video!
Interesting stuff - I didn't realise that this is so readily available with minimal equipment. I do use an SDR for repairing vintage radios but I don't have any sort of dish for this satellite stuff. Would be interesting to explore, though.
Like the umbrella idea for a rainy day, with a bunch of bright daylight LED strips to make your little area a sunny day. A portable power brick would be ideal. I like the idea of collecting my own satellite imagery, sounds like a great project. I’m happy I stumbled upon your channel, just subscribed.
My buddy brought me over an old Dish satellite dish, one of the more oval shaped common style. Gonna solder up the little feed with the 3d print support structure you had in one video.
I still can't believe how much different the live satellite cameras are than these public cameras. I mean the first time I saw the live cameras on every satellite my mouth dropped open. We were told never to look at these cameras, so every time I worked alone, like on Christmas, I watched them, and they were just mind-blowing. So detailed. So clear. Like looking at Google Earth in real time. I really miss that job I saw so many cool feeds
NOAA was using 100 foot dishes when we built the turnkey system for Wallops Island. Encryption uses more power aboard a satellite, so it doesn't make sense.
It's very important to have a pigtail adapter on that/those usb devices. They have tremendous leverage if just plugged straight into a phone or laptop. One tug, or trip on a cable, or antenna blows over, and you're looking at a relatively expensive amount of damage to the USB jack.. Spend the extra few bucks for a short dongle/pigtail. I always have extras for my non tech friends who struggle with stuff like this... I hand them one, and they instantly get it.
Good call! Sellers call them a "USB C Extension Cable" on *m*z*n's marketplace. I see 0.6' (8"/18mm) ones and a few 4" ones. This includes a OTG+charging port which comes out as a C female (10W) and an A OTG port. Handy.
I use it as my baseline a lot, for testing and aligning antennas. I've manage to pick it up with some pretty marginal gear, although I'm not always able to decode good images with the flaky antennas!
Been watching your channel now for sometime and decided to subscribe! You put stuff together and hopefully inspire young people to continue the quest to explore electronics and physics!
For your antenna scafolding, move your bottom and middle support braces up to equally split the distance (height wise) on the calculator. I had the same problem with mine. They were 30 turn antennas.
Another great video Gabe! I've been getting some pretty good results from the 137Mhz NOAA 15, 18 and 19 sats using a modified V dipole antenna, RTL SDR V3 dongle, SDR ++ and WXtoIMG. I've never had ANYTHING from Meteor M2-3 though. I'm dying to have a go at getting HRPT images, so your videos are proving really useful and inspirational. Greets from the UK.
The geekery here is 11/10. Nice work, Gabe. I wonder if a larger diameter shallow mesh dish would be something that you could build. I know it would take a lot more to keep stable, and to aim, but I'm betting you'd get a much cleaner signal. I suggest a mesh to keep the weight down, and also to give a clean reflecting surface. I suppose it just needs to be dense enough so as to reflect signals properly. I'll bet there's a tool out there that will permit calculating mesh density for a given signal spectrum, etc. Just a thought that I think would be cool, but probably a bit spendy and cumbersome. Maybe a larger motorized mount for it? Have fun! :)
For the printed scaffolds, thinking that if were broken into five parts it would work better. Print the legs flat and the two rings with holes in them to index the legs you may have better results Some assembly required at the end but figure you'll get a better print
Hey man, I love these videos. In another video you said you went to graduate school to study GIS, I’d be very interested to hear your perspective on the GIS sector, if you work in GIS now or what. Only if that’s something you want to share of course! Thanks again for making these videos
I haven't directly worked there for a few years. When I graduated the only people using it were government agencies and real estate. I couldn't find a government opening so I drifted into real estate and kind of ended up there. ESRI tried to hire me but I hate Los Angeles and remote work wasn't as much of a thing yet. There are probably a lot more options nowadays but I'm a little out of date on modern GIS topics. I still use it occasionally and I have some video ideas involving GIS, but no time to do them :-D
Thank you for this great video. Not that I think you will need suggestions for a video, but if you has plans to revisit the cheap parabolic antenna subject. You may try to vacuüm form a antenna dish with mylar around a round mortar tub. Or other round sealed container. And a vacuum cleaner You may want to paint the mirroring surface though otherwise you will burn your receiver.
I ment to send this last video I mean, i wasn't looking for a direct answer for the LNA I just wanted to know if something like that would even work or if it would destroy the diodes on my rtl-sdr v3. And thank you for making me realize I haven't updated sdr++ in 4 months😢.
thanks : 18'20s : this is BPSK modulation. It could explain why the RX agc gain value has few effect: With numerical modulation you have a big threhold effect : if your are above this threshold the average gain dont improve reception . Bit 1 ou zero remains 1 or 0. ( basic explanaion ) If you see 4 points : this is QPSK modulation : better datarate but higher SNR needed.

11:08 1000% for your cable modem at home or any catv connection as well.... keep that braiding out of the way as well... need em clean and level and tight.
i´m fairly new to SDR radio but what i have started doing to keep the centre pin from moving around when soldering SMA connectors is to first solder the signal wire to the centre pin and then putting a drop of super glue on the base of the pin before assembling the connector and soldering the screen to the connector body.
I wonder if an umbrella, covered in fiberglass and resin, and then split into reassemblable segments would work. That way it can have a reflecting paint sprayed on it, can be stored and reassembled easily. For those that are fiberglass rich that is..
A very comprehensive and interesting video about my favorite topic, satellites. There were also some things in there that were new to me, better to use an umbrella than no satellite dish at all. Perhaps there will also be a video about amateur radio satellites, as there are several in orbit, and even the ISS now has an X-band repeater that receives on 145.990 MHz and retransmits it on 437.800 MHz. It seems that very few people know that receiving weather images and decoding them is completely legal. I look forward to every new video on the subject.
If you're using an on-the-go adaptor, get one with a cable between the plug and the socket. Saves putting a strain on the connectors at both ends, and could save you an expensive repair. Ask me how I know this. ☹
Great tutorial. I am trying to get into this stuff. I have an old dish from 2014. To be fair it is a large one (bit over 3 feet). So this is very helpful. I live in Norway so I doubt that I will be able to get GOES data unless I get a much bigger one. I hope that the European weather satellites also are L band satellite, then I could get data with the same method.
There are some interesting things you can get in Norway, a lot of low-earth-orbit satellites dump their full orbital data when they pass over Svalbard. I only see one that does L-band (according to www.satdump.org/Satellite-List/), and you'd have to aim the antenna somehow. www.youtube.com/@dereksgc has a lot of good info on that!
Solid video! Isn't it great to get data without the middlemen? Edit: I love that your feedhorn is a plastic funnel with 12ga and a cookie tin lid. Horses for courses.
I want to try an empty swimming pool (childs or even inground) coat it and have a moveable feedhorn, perhaps on cables. Something similar to The Arecibo Observatory. Would be an interesting project.
You can try to reduce the receiver noise figure by reducing the insertion loss before you're first lna. Agc may not give you much as shown because the noise figure of your lineup will be dominated by the loss/noise figure of your first component after the antenna. Sometimes changing from a SAW filter to a ceramic filter improves things because they have a lower insertion loss.
SMA connectors are not intended to be used in the way we use them, they are supposed to be inside equipment and connected once and never messed with again. I like to support the SDR so there is not so much load on the fragile connector. I like the scientific method of doing this so hot glue and a piece of wood.
Encryption would also add a thick layer of potential problems if there is noise. Unencrypted is easier to get something from even on a bad signal. Even with error correction etc, those are just solutions to work around problems with encryption of non sensitive data. I am not saying it isn't solvable, but the technical house of cards would get unnecessary big. ... As far as I know. Correct me enough and I'll remove this comment :)
Always check the phone specs as OTG capabilities of many phones are either permanently disabled or crippled by the manufacturer with very few capable of being activated. Amongst those that do function fully some just are not powerful enough to run SDR applications and in some battery drain with SDR receivers is so high that they become useless. If you are not sure or can't find the information give it a go as you may be pleasantly surprised when it works.
SMA connectors were never really designed to be used for equipment that was going to be moved around a lot, or plugged and unplugged a lot. They were really designed for microwave (up to 18GHz) use inside equipment enclosures for connecting modules together and with lots of good strain relief and cable management. But their use has expanded into communities that may not appreciate their heritage nor their limitations.
The original SMA cables were rigid, or semi rigid coax that didn't alow the center conductor to move. We made all of our cables in house at Microdyne when I first started working there. A final step for SMA was a weight that was screwed onto it, to test the joint's strength. Naer the end, we were using a very tiny snap in connector on one product. They had to be ordered premade because the tooling was computerized and only leased.
Yeah it seems like EVERYTHING is SMA these days. Which is actually kind of nice, I remember when Wifi cards used MCX and SMB and even tinier BS that would break if you breathed on it. SMA is actually kind of refreshing, and I no longer need a box of proprietary pigtails for every gadget.
@@saveitforpartsWe used about ten different types of RF onnectors at Microdyne, and both 30 and 75 ohms coax so the RF benches had a lot of cables to test boards and subassemblies.
The constellations your seeing in SatDump is probably a representation of the signal's modulation. Many satellites use what is called Phase-shift keying to modulate a digital signal. I don't know that much about it but here is the Wikipedia page for further reference: en.m.wikipedia.org/wiki/Phase-shift_keying
So, any plans for an antenna mast/tower? Be pretty cool to have ham band antennas, lora, and a dish above the tree line. What about sticking one out at Sandland? (That’s the name, right?) Maybe set it up with backup power and remote administration and redundancy. You could make multiple video series about something like that! Appreciate the content and sharing the knowledge!
Sandland is getting the radome and radio telescope. I'm too lazy to put up a bit antenna at home right now, I don't even have space for a real ham shack!
I think You tube deleted my last comment because i mentioned some other platform which would be good for us all interested in this hobby commenting helping each other very annoying ! Any case if you do with a bit a bit luck and big brother AI does not pick this up i might be talking about some platform which would be much better than here to help others interested in chatting to each other .....i don't know i can but try ! But love the videos and the help experiments on the dishes feed horn antennas great work i will try your ideas here in Australia hope to show my work when i can do it .
Wow great video once again (and for providing all those links) in the description. Saved Me tons of time not having to find it my self. (Did you ever try this Dish) On the GOES 16 Satellite. This way you Don't have the hastle of tracking it. Perhaps the result would be a clearer set of images. (Less Static) Thanks again 73s 📡👍
This dish is a little too small for the GOES satellite, I think I tried it in a previous video. I keep meaning to set up a bigger dish for that, but I'm lazy and haven't figured out exactly where to bolt it to the garage!
Forgot got to mention as an idea i am about to try using a pair of free geared DC motor driveway car gate openers i am going to use instead of actuators on my 2m C band mesh dish they seem to be very strong and do the job easy once mounted
Yes i was lucky as they were free i was not expecting to be able to move the dish via any thing i would have placed my dish pole a little forward to move up down any direction than just the geo belt ...OH well ! keep up the good work on the satellite dishes and different feed ideas so helpful know what can work and what can't ! Your very inspirational on all this and very good at it ...
Have you tried the heavens-above app (available on Android)? It doesn't have the full "AR" view but it does have an aiming view that uses your phone's angle. I haven't had issues with it.
The physics would say that the parabolic dish will reflect all signals at the focus point of the. Parabolic dish, which is most likely at the horn, not sure your helix which isn’t at the focus is making the most of the parabolic reflection. Have you ever tried a double helix antenna, just two springs mounted side by side, one left wound, one right wound and point them at the sat? Curious if it gets more signal and would eliminate the amp
I see clear difference between lower and higher resolutions. But can you tell us, since you have those png images, what megapixels are we talking about. Thanks for video!
@saveitforparts Can you please share HW info of that laptop used for decoding? I would like to get a better idea of what computing power is necessary. Thanks! BTW I love your satelite videos, it is such an inspiration of what can be done with such and ordinary HW.
I honestly don't remember, I'd have to look at it. It's someone's older one they sent me, probably at least 10 years old. You shouldn't need too much for basic satellite stuff, I've done some recording and processing with a Windows XP-era computer and it worked OK.
They should be, I think I mentioned that I get a commission. Pretty sure I've made like $5 in the last year from that Amazon thing, and it takes months to pay out, so I don't think much of it so far.
Weird question: how long could you expect to keep receiving useful data from weather satellites and such like this with your kit, in the event of a disaster that takes out their ground stations?
very unpredictable, but the only thing that will take these sats out will be collisions and space rocks, i hope that by the time the apocalypse comes, theyll have figured out how to automate that...
What I'm wondering is how you would track them without the help of these internet based services Maybe the timing and path through the sky are really consistent though, I don't know
@@maxscott3349 Their path is well known and maintained. Satellite terminals handle the tracing. What id more fun is tracking then on a ship in rough water. It has to both track, and compensated for the ship's shading and rolling. A friend of mine retired from the Merchant Marines as a radio operator in the '80s. Large cargo ships were installing first generation satellite communication.
Another super informative video, thanks! I notice that with your tracker setup, it's forced to rotate horizontally 180 degrees when it passes overhead. Would it be possible to just keep using the pitch motor to continuously track it without having to rotate, or does the mount have a mechanical limitation that prevents it?
The mount doesn't have a physical limit, although it does have a little slop in the internal gearing so it "flops" slightly when the center of gravity goes over the top. I'm using code written for TV antenna rotors, so this is just the way they programmed it. I'm currently struggling with updating some of the code for the thing so it can be a radio telescope, but I'm not actually much of a programmer myself so I'm not sure how easy it is to change that feature.
hey, great vid as always, i love your stuff, thanks for all your work. Do you get that alot that you look like youre the big brother of angus from makersmuse? :)
I've heard about it and occasionally look through the website, but I'm honestly still a little confused about how it works. I'll have to see if someone has a simple how-to guide on the whole project.
I wonder which SDR device would be best for these satellites? I have several different types, but have only used the RTL-SDR for satellite reception. It seems kind of weak. Most of mine are $300USD or less. Im sure a $2,000 unit would be great! Lol
If you can get one with super high bandwidth that can see more of the radio spectrum, I've seen some interesting stuff done with those! There are a few satellite signals that need much more bandwidth than the cheap SDRs can handle.

@@gorak9000 Downside of lna first is that you pass out of band noise to the lna which can saturate it depending on the noise environment.

SMA connectors are not intended to be used in the way we use them, they are supposed to be inside equipment and connected once and never messed with again. I like to support the SDR so there is not so much load on the fragile connector. I like the scientific method of doing this so hot glue and a piece of wood.
Back in the Mid 1980s, ANTIC Magazine plublished a project for Atari computer owners on how to receive & processs WeFAX data.
Encryption would also add a thick layer of potential problems if there is noise. Unencrypted is easier to get something from even on a bad signal. Even with error correction etc, those are just solutions to work around problems with encryption of non sensitive data.
I am not saying it isn't solvable, but the technical house of cards would get unnecessary big.
... As far as I know. Correct me enough and I'll remove this comment :)
This is cool. I think I need to re-up my Ham ticket. 73s.
Look at passive radar methods (using radio/TV broadcasts to detect planes). Maybe you can do cool video about
Thx
Always check the phone specs as OTG capabilities of many phones are either permanently disabled or crippled by the manufacturer with very few capable of being activated. Amongst those that do function fully some just are not powerful enough to run SDR applications and in some battery drain with SDR receivers is so high that they become useless. If you are not sure or can't find the information give it a go as you may be pleasantly surprised when it works.
SMA connectors were never really designed to be used for equipment that was going to be moved around a lot, or plugged and unplugged a lot. They were really designed for microwave (up to 18GHz) use inside equipment enclosures for connecting modules together and with lots of good strain relief and cable management. But their use has expanded into communities that may not appreciate their heritage nor their limitations.
The original SMA cables were rigid, or semi rigid coax that didn't alow the center conductor to move. We made all of our cables in house at Microdyne when I first started working there. A final step for SMA was a weight that was screwed onto it, to test the joint's strength.
Naer the end, we were using a very tiny snap in connector on one product. They had to be ordered premade because the tooling was computerized and only leased.
Yeah it seems like EVERYTHING is SMA these days. Which is actually kind of nice, I remember when Wifi cards used MCX and SMB and even tinier BS that would break if you breathed on it. SMA is actually kind of refreshing, and I no longer need a box of proprietary pigtails for every gadget.
@@saveitforpartsWe used about ten different types of RF onnectors at Microdyne, and both 30 and 75 ohms coax so the RF benches had a lot of cables to test boards and subassemblies.
The constellations your seeing in SatDump is probably a representation of the signal's modulation. Many satellites use what is called Phase-shift keying to modulate a digital signal. I don't know that much about it but here is the Wikipedia page for further reference: en.m.wikipedia.org/wiki/Phase-shift_keying
So, any plans for an antenna mast/tower? Be pretty cool to have ham band antennas, lora, and a dish above the tree line.
What about sticking one out at Sandland? (That’s the name, right?) Maybe set it up with backup power and remote administration and redundancy. You could make multiple video series about something like that!
Appreciate the content and sharing the knowledge!
Sandland is getting the radome and radio telescope. I'm too lazy to put up a bit antenna at home right now, I don't even have space for a real ham shack!
I think You tube deleted my last comment because i mentioned some other platform which would be good for us all interested in this hobby commenting helping each other very annoying ! Any case if you do with a bit a bit luck and big brother AI does not pick this up i might be talking about some platform which would be much better than here to help others interested in chatting to each other .....i don't know i can but try ! But love the videos and the help experiments on the dishes feed horn antennas great work i will try your ideas here in Australia hope to show my work when i can do it .
Amazeballs! Satellite tracker paying dividends.
Love the channel Great job! Thank you
Wow great video once again (and for providing all those links) in the description. Saved Me tons of time not having to find it my self. (Did you ever try this Dish) On the GOES 16 Satellite. This way you Don't have the hastle of tracking it. Perhaps the result would be a clearer set of images. (Less Static)
Thanks again 73s 📡👍
This dish is a little too small for the GOES satellite, I think I tried it in a previous video. I keep meaning to set up a bigger dish for that, but I'm lazy and haven't figured out exactly where to bolt it to the garage!
@@saveitforparts To describe yourself as "Lazy" 👎 I Disagree . (With all these Videos) And a Book in the works.. When do you Sleep?? 🛌
Forgot got to mention as an idea i am about to try using a pair of free geared DC motor driveway car gate openers i am going to use instead of actuators on my 2m C band mesh dish they seem to be very strong and do the job easy once mounted
Cool! That sounds like a fun project.
Yes i was lucky as they were free i was not expecting to be able to move the dish via any thing i would have placed my dish pole a little forward to move up down any direction than just the geo belt ...OH well ! keep up the good work on the satellite dishes and different feed ideas so helpful know what can work and what can't ! Your very inspirational on all this and very good at it ...
Have you tried the heavens-above app (available on Android)? It doesn't have the full "AR" view but it does have an aiming view that uses your phone's angle. I haven't had issues with it.
The physics would say that the parabolic dish will reflect all signals at the focus point of the. Parabolic dish, which is most likely at the horn, not sure your helix which isn’t at the focus is making the most of the parabolic reflection. Have you ever tried a double helix antenna, just two springs mounted side by side, one left wound, one right wound and point them at the sat? Curious if it gets more signal and would eliminate the amp
His focal point hits the tin lid which is 1/4 wave behind the helical antenna.
Thank you, keep working.
Thanks for all the information. How likely Would a 50cm dish work?
I see clear difference between lower and higher resolutions. But can you tell us, since you have those png images, what megapixels are we talking about.
Thanks for video!
@saveitforparts Can you please share HW info of that laptop used for decoding? I would like to get a better idea of what computing power is necessary. Thanks! BTW I love your satelite videos, it is such an inspiration of what can be done with such and ordinary HW.
I honestly don't remember, I'd have to look at it. It's someone's older one they sent me, probably at least 10 years old. You shouldn't need too much for basic satellite stuff, I've done some recording and processing with a Windows XP-era computer and it worked OK.
hey man, if those aren't amazon affiliate links in the description, you should change that
They should be, I think I mentioned that I get a commission. Pretty sure I've made like $5 in the last year from that Amazon thing, and it takes months to pay out, so I don't think much of it so far.
Love your content, how do you automate the NOAA Sat Dumps, that would be a great content to share.
I have it on my to-do list to do a video about the Raspberry-NOAA system I use. I keep meaning to update that and move the antenna to another spot.
Weird question: how long could you expect to keep receiving useful data from weather satellites and such like this with your kit, in the event of a disaster that takes out their ground stations?
very unpredictable, but the only thing that will take these sats out will be collisions and space rocks, i hope that by the time the apocalypse comes, theyll have figured out how to automate that...
NOAA 15 is over 25 years old and still trucking
There are multiple control ponts for the NOAA system. What usually ends a satellite's ueful life iswhen it runs out of fuel for course corrections.
What I'm wondering is how you would track them without the help of these internet based services
Maybe the timing and path through the sky are really consistent though, I don't know
@@maxscott3349 Their path is well known and maintained. Satellite terminals handle the tracing. What id more fun is tracking then on a ship in rough water. It has to both track, and compensated for the ship's shading and rolling. A friend of mine retired from the Merchant Marines as a radio operator in the '80s. Large cargo ships were installing first generation satellite communication.
the fact that people are shocked that weather sattilite data is free says alot about how we have been conditioned to think about the world
Another super informative video, thanks! I notice that with your tracker setup, it's forced to rotate horizontally 180 degrees when it passes overhead. Would it be possible to just keep using the pitch motor to continuously track it without having to rotate, or does the mount have a mechanical limitation that prevents it?
The mount doesn't have a physical limit, although it does have a little slop in the internal gearing so it "flops" slightly when the center of gravity goes over the top. I'm using code written for TV antenna rotors, so this is just the way they programmed it. I'm currently struggling with updating some of the code for the thing so it can be a radio telescope, but I'm not actually much of a programmer myself so I'm not sure how easy it is to change that feature.
Could you make a short showing how the saw bird is connected to the antenna, like what's between it's port and the dish, please
I actually showed the build process for the helical feed here: th-cam.com/video/vNo8Kjflbtg/w-d-xo.html
wow excellent.
hey, great vid as always, i love your stuff, thanks for all your work. Do you get that alot that you look like youre the big brother of angus from makersmuse? :)
Haven't heard of him!
Have you looked into setting up a Satnogs station? Its a very cool community.
I've heard about it and occasionally look through the website, but I'm honestly still a little confused about how it works. I'll have to see if someone has a simple how-to guide on the whole project.
I wonder which SDR device would be best for these satellites? I have several different types, but have only used the RTL-SDR for satellite reception. It seems kind of weak. Most of mine are $300USD or less. Im sure a $2,000 unit would be great! Lol
If you can get one with super high bandwidth that can see more of the radio spectrum, I've seen some interesting stuff done with those! There are a few satellite signals that need much more bandwidth than the cheap SDRs can handle.
