Russian Weather Satellite Follow-up (Meteor M2-3 Video #2)

- Since last week's video on this satellite got a lot of interest, here's a follow-up! I wanted to address the most common questions from last time and correct a couple minor errors. I also wanted to try some different techniques of listening to this satellite, including different frequencies and other antennas.
More information on the satellite here: usradioguy.com/satellites/met...
More info on the image scanner system: en.wikipedia.org/wiki/Whisk_b...
This is the type of rooftop antenna I use, connected to an SDR and Raspberry Pi computer: usradioguy.com/wp-content/upl...
This is my current favorite software-defined radio for general experimenting: www.rtl-sdr.com/rtl-sdr-blog-...
For better 1.7ghz / HRPT reception, I use a SAWbird+GOES filter/amplifier gadget: www.amazon.com/Nooelec-SAWbir...
The folding satellite dish is a "Cyberex CN7500". I don't think they've been made since the '80s, but this company makes something similar: sub-lunar.com/products
I'm mostly recording satellite signals on Linux using rtl_fm, with the following settings (these might not be the best in every situation, I'm still learning how to do this!):
timeout 15m rtl_fm -M raw -s 120000 -f 137.1M -E dc -g 48 -p 1 (right angle bracket) raw_dump.raw
I'm then using sox to create a wav file:
sox -t raw -r 120k -c 2 -b 16 -e s "raw_dump.raw" -t wav raw_dump.wav
And then I process that wav file with SatDump: github.com/SatDump/SatDump
I also tried streaming from my computer with the SDR and antenna, using rtl_tcp as follows:
rtl_tcp -f 137.1M -s 250000 -b 16 -a (ip address)
And then connecting from the Recorder tab in SatDump. That seemed to work pretty well. I was told SDR++ works better as the streaming source, but could not get it to install on my Raspberry Pi.
More info on HRPT and antennas here: sgcderek.github.io/blog/begin...
I've also tried LeanHRPT, but I did my recording wrong for that: www.rtl-sdr.com/leanhrpt-a-se...
(UPDATE: I heard that Meteor M2-3 switched BACK to 137.9mhz after I made this, but who knows which frequency they'll finally settle on).

If the Earth was flat, cats would have already pushed everything off the edge.
I have spent my entire life trying to find evidence that the earth is round and here on TH-cam you gave the conclusive evidence. Thank you 😅
yes
I'm waiting for a flat earther to drive off the edge. Or take a boat off the edge, still no photos of the edge yet???
😂🤣
lol! 😂
Absolutely love this guy. Giving me the old cody's lab vibes
So in a few short years, this guy too will be living in a hole in the ground in the desert? Sad... Oh, actually, he'll be living in a sandstone cave - gotta keep it straight!
Certified Cody's Lab vibes!
"Try to learn something every day." Words to live by.
Before I found this channel I never even knew it was possible to just set up an antennae and listen to satellites. Even though google earth in VR exists this is still interesting stuff!
Same, if I didn't rent I'd be putting up an antenna to get satellite images for the hell of it
Beautiful thing is these are raw images in real time without censorship or centralized management, granted they can be turned off and controlled by their government agency but the raw data just comes straight down.
Back in mid 80's I had a Radio Shack Color Computer3. I came across a program in Rainbow magizine called " WEFAX " Weather facsmile. I had to buy a shortwave radio to pick up the signals. I forget which sat it was but it scanned one line at a time and filled the screen after 12 minutes. Was so cool then to be able to do that.
I had a Radio Shack model 100, fun little laptop! Don't think it would do much for graphics though!
Back then it would have been one of the many land-based shortwave transmitters pumping out weather charts on a schedule. There's not so many around any more, but they are still out there.
I am really impressed that you were able to get the higher frequency signal captured! Also huge props to you for churning out so much content. It isn't an easy job and I think I've gathered it isn't your day job, either. I'm glad you are able to make time to have fun and also make the effort to edit and share it with us.
Here's to your channel continuing to grow, man. 🎉🎉
You should never feel the need to justify why you are doing this. It's awesome and you have so many subscribers and viewers for a reason.
Something to know about LNAs. They work best when they're right up at the feed horn. Having more than 10-15cm of cable between the horn and the LNA turns your LNA into a kinda-ho-hum LNA. Now, in practice, this may not matter that much if you're looking at signals that are fairly strong, into a dish that's fairly large. But it's something to keep in mind.
Yes and also try and use an elbow connector to allow the LNA to drop downwards from the feed to avoid putting stress on the connectors. I have seen pictures where the SMA connectors were torn away from the PCB.
My question is, what's the point of people asking "what's the point of doing these things"? It seems self-evident to me, and that's a terrible question they're asking. This channel is just awesome!
It's people trying to justify themselves for never doing anything by questioning why someone else is doing something. Ignore the trolls and they'll go away.
This is one of those hobbies where the answer is simply because you can, or you want to see if you can.
Images from these satellites are often used by russian cargo ships in Arctic to monitor ice fields during navigation season. Unlike weather, you can't get that information from other sources rather than satellite. Very useful.
I think the thumbnail from the first video was a big reason as to why it did so well. It’s fantastic for getting peoples attention and interest. Plus the title of course, with Russia being such a topic at the moment.
This has quickly become my new favorite channel, and I’m now eyeing various scraps around the house for an antenna. 😂
Would love to see you get data from the NOAA satellites if that’s possible!
I've done a couple videos on the NOAA Polar orbit satellites: th-cam.com/video/yzLUsi8MsRQ/w-d-xo.html and th-cam.com/video/WM99A1uUprQ/w-d-xo.html
You may be stumbling your way through these things, But your light years ahead of me! Great video...keep up the good work.
Love to see more people using the RPi for radio stuff! Looks like the foundation is ramping up production as many stores seem to have them in stock now. Thanks for another fun and interesting video!
Nice, I'll have to buy another one if they come down in price!
Yups, I finally managed to purchase a 4B 4gig Pi in Australia this week.
Can't tell you how excited I was to see your newest vid pop up on my feed. Great stuff!
My new favorite channel on youtube! Thank you from a brand new subscriber.
I love the extra info you provided in the description for others to try this as well
Don't stop enjoying your hobby. We love & appreciate you! Well done.
The radio and satellite videos are always inspiring. My current challenge is to capture signals like that from my small apartment window. It's tough, but also fun!
The stuff you do is very awesome and love that you try to link everything you use so people can learn and use it too!
Love the channel thanks for putting in the effort and sharing.
Awesome tech and awesome content. Not only are you learning all about this but you’re helping countless others learn from your experience!
Dude you are doing so well. This stuff is so fun to watch. I got a sdr myself and have been playing along at home. Keep it up eh.
This channel is my favorite now
The camera that kind of scans the earth is Pushbroom Scanner (Pushbroom Camera). You can find it on wikipedia and the scanner scans like earth in lines so thats why sometimes you have black lines in your picture, its because your signal got smaller and thats why the SatDump (and also any other app) couldnt really read what was in that audio you listened to. And the options you tried after, other and other they can like set sensitivity so you can see the image behind the black lines, thats because its smaller quality, by default SatDump has parameters and thats why other parameters helped you get a nice picture.. Keep it up :)
Great video. I am glad this channel popped up on my TH-cam recommendations. Love the honest, narrative, ...almost conversational style 👍
I have been watching your videos for a long time now.
I absolutely LOVE your non professional approach to everything you do.. Don't ever change that!
I have learned a lot with you along your journeys..
You've always got a good attitude man. Keeps me coming back.
Despite any comments you may have had, I love all the stuff I have seen so far. Keep it coming. I find it very interesting just as you do.
Well done with the views on your previous video!!!! I only discovered your channel this week thanks to that video ❤
I really enjoyed your wrap-up talk at the end. Keep it up. You're putting out some great content! I've been a ham since the mid-90s and I've listened to easysats as they flew by overhead, but I've never been able to complete a QSO. Your channel is bringing back some fun old memories for sure, and your attitude about it all is top notch. Well done!
I'm sure these are a ton of work to make, but they are so fun. I love watching your videos.
Your positive personality really shines through as well. !
I really enjoy your content, you should do a showcase about specific satts....theory craft about interesting aspects, then try to talk/listen to it and see what you get. I think that'd be a cool format
Another great video! I arrived a couple of weeks ago (courtesy the algorithm) and I'm glad I did. I find incredible value in being "scrappy" and being able to just throw something together to accomplish a goal. Your Sandland project is really cool too 😎 Don't let negative comments sway your mood, you're doing it right!
I could listen to you for hours, especially on this subject!
Greetings from Germany
This is amazing! I love your videos; keep doing this stuff.
Another brilliant video Gabe, always good to learn something new and get enjoyment out it too, especially if there’s some random duck tape involved too! Looking forward to seeing more of your projects soon. Best wishes
I love the way you 'hack' stuff to try and get it to work. You teach a valuable lesson in perseverance. Keep up the awesome work!
We don't care if the Flearfers are triggered. Hell at sometime or another "Those Kind of People" will forget to breathe.
Thanks for another awesome vid!!
Dude you made a MEGA WORK! People who are doings stuff like people who "do" stuff. Great Job man!
Heya Gabe, consider this a friendly nudge to get going on that motorized mount, future you will be glad to have it around and working. Loving the satellite stuff. Glad you're having fun :)
I enjoy learning with you.
Great series! I'm an Extra class ham and have tried working V/U satellites and that seemed very tricky. Receiving microwave HRPT signals from weather satellites is even trickier in my mind, so to get any usable signal at all you're doing very well indeed. I love your attitude and your approach - the biggest hurdle for me is always just getting out there and trying it when I'm not sure it's going to work. Keep it coming!!
Thanks for the followup! The first video brought me to your channel.
You don't have to explain your reason for a hobby. It's something you like doing -- that's what a hobby is. Some people like to color, some people like to paint, sew, crochet, and so on. I personally enjoy doing a lot of the radio / antenna experiments that you do -- hence I found your channel -- and I also love audio equipment, old computer stuff, SBCs, etc etc etc. It's curiosity about what's out there and how things work -- that's what drives people like you and me and your viewing audience. Nope - you don't have to explain it to us - we get it :)
Ah, but it's WORTH the comparison.
Work is or should be defined as a hobby that supports,
Like the hobby of trees and ocean algae making free oxygen. They benefit, and so does everything else.
-You, me, everybody benefits from a good, dedicated, generous hobbyist. Breathe - that's one of my best hobbies - it builds trees (and blueberries)
Thanks for sharing. Charles
Anyone asking "What's the point?" is clearly not the target audience for this channel. Love the content!
Yeah, not sure why they bother watching :-P
Bro you are a kindred soul
Great work and follow up. Very cool!
It's all about that "I'll be damned!" moment.
It's interesting to think of someone living "off grid" using satellites as an important datapoint. Like the informational equivalent of navigating by stars.
I love the cat that shows up in the right monitor's reflection at 5:20
Well said explanation on the hobby at the end and why you do it 🍻
new fan here, the last russian satelite episode was my first episode so i guess i have a lot of old content to catch up on.
i dont know what you should do next but i love the satelite stuff.
recently moved but i cant wait to try more projects once i get setup
Here we go! You know 👍
I absolutely enjoyed and learned from this video.
Fantastic channel thanks for having something interesting to watch
One of the best channels on youtube 👍👍👍👍👍
Nice work, and cool project
Great video, appreciate you brother man
amazing job, thanks a lot for KINO! Waiting for upgrades and future series ! Cheers bud!
Love your channel,keep it up! ❤
And here's another fine hobby you got'n me into 🙂
Thanks for the informative video
bro if i can say one thing to you...stop selling yourself short my man.
this is all new knowledge to me and awesome to add to my library of interesting things.
your one clever cookie bro, got yourself a new sub cheers.
Idk how this all works but it is just so fascinating
Cool video! I remember doing this with my dad. Never received much from Russian sats, but NOAA worked well. George, M1GEO!
Nice video and nice hobby ! I'm currently using a SDR to track planes, and youtube suggested me your video : what about trackin satellites !! That must be fun, but requires a bit more hardware and time. Thank you for sharing, that's inspiring
Wonderful video
“What’s the point?”
It’s because we want to and because we can. Great experimenting, keep up the good work!!
Thanks for the info!
10:20 You can install a plastic plate in a linear converter, to receive a signal in circular polarization. It must be installed at an angle of 45 degrees relative to the pin in the converter.
There are few better feelings than that "EUREKA" moment when you put something like this together and it works.
haha heyy, i love your videos.. did people really ask u why u do this? i think its so obvious and i love that u do it, i never had a clue how communication with space satellites is working. this stuff is so fascinating, thank you for letting us all know kind sir :)
So interesting. Such a good recommendation by TH-cam! Love this content
No need to justify your hobby! It’s our benefit that you show this stuff, really interesting
You're a legend
This episode had me laughing the most. Love the subtle humor
That's already more than 4 views x) (Thanks for the follow up !)
Was hoping to see a follow up!
Спасибо, товарищ!
good job
Awesome video! Years ago I downloaded a few images from Russian weather satellites. I Can't remember which Meteor M it was (M2 etc). I did it indoors, and all I had (all I still have) was a television "rabbit ears" antenna, connected to a little portable HDTV indoor/outdoor antenna (The combination seems to work nicely). It was time consuming getting through all the steps, but finally got a few images. LOTS of errors, but it was "proof of concept" more than anything. The point is, you don't need much, no fancy equipment to have fun with SDR. I've downloaded images from the ISS, NOAA/Russian Satellites, Recently listened in to an ISS Ham Radio "fly-over" contact with a local High School (with Astronaut Dr. Josh Cassada, I have a TH-cam video on it). I can decode medical pager info (using PDW Paging Decoder Software) and SO much more!
Hey man. Hope you're doing well. Enjoyed the video.
And thanks for inspiring me to buy some antennas and trying it myself
Nice! It's a fun hobby. Frustrating sometimes, but still cool.
Excellent videos! One tweak to consider is to mount the LNA directly onto the feedhorn using the minimum amount of rigid coupling adapter you can. Try to avoid any coax between the horn and LNA. It's fairly astounding how much loss you get in small diameter coax. If you're at threshold, that can bring you back to functional.
Just getting into the hobby, will keep this tip handy for the future. Thanks!
@@BerthaTurtleOfficial You're welcome, and welcome to a cool hobby. Just for your info, the tweaks I would make to this setup would be to mount the LNA onto the feedhorn connector directly (for lowest loss), and then to run a feed in RG-6 coax (for lowest loss) from the LNA output down the support pipe to the SDR which I would mount on the support pipe just behind the reflector and next to the swivel mount. That allows you to have a Power+USB only connection to the dish and gives the least loss. If the configuration allows, one stop better might be to put the feedhorn, LNA, and SDR together where the original LNB was with no coax at all, or just one short piece of rigid coupling.
Thanks! I did mount the LNA straight to the little QFH antenna at the end. If I pull out the cantenna again I'll try that as well.
Good for you. Your vids are pretty great. I'm glad you're getting some views
Man great job I love your video! I just found something to do!
keep up great work!
I loved the cat peering into the fish tank in the background at around the 5:30 mark. Such a cat thing to do.
Can't wait to see the Cyberdeck 2 build!
Yeah v1 is rapidly disintegrating, and I've already thought of a few improvements. Just need to find the time for it, like with everything else! V1 sat on the to-do list for at least a year before I found time to build it.
Viewer #3 here. Pretty cool stuff 👍
Love the longer vids yo
So freaking cool
I connect my RTL-SDR directly to the antenna. Then I use USB extension cables. Less current but the receivers don't take much. Works for my ADSB stuff.
Ha! caught it at 4 views. love the videos man!!!
Yep, you are wicked smart.
I chuckled at the "what's the point?" bit. - Ohhhh the many points! I for one just think it's good to know how to do things analog or by hand. Just knowing how stuff works in general. 👍
I really want to try this at some point
It is fun and I really enjoy it😎😎
