Is North Korea's Spy Satellite Legit?

- Recently North Korea launched a "spy satellite" known as Malligyong-1. Is it actually a working satellite, or just a political stunt? I took a look on several radio bands and couldn't find any evidence of this satellite doing anything. I also spoke with some satellite experts who haven't been able to find signals either. Has it failed? Never properly deployed? Is there another frequency I could use to listen for it? If you have any details, let me know in the comments!

I have never checked my cat's polarization, but I know she isn't radioactive.
ROFL!!!
Good for You...Polarization is the new Usa Sicknesa
...she IS in the infrared. Just sayin'
Much hope that she's really hairy
everything is radioactive dude, you get more radiation for just kuddeling your partner in bed.
I left a thumbs up as soon as I heard, "Remember to always check the polarity of your cat before doing any serious ham radio work." That's when I knew I was watching professional level content.
Yes, this is excellent advice to do a cat polarity check, because you never know which way round they might be. 🙂
Bingo, his work feeds my projects. They are legit.
What if your cat is CP?
@@StringerNews1 thats dogs depending on which way they chase their tails RCP or LCP
I was just chatting with my wife about this launch and said "I watch this really awesome guy on youtube who I bet will try and track it." And then got to explain to her all about your absolutely wonderful channel and how fascinating it is. Favorite channel I have found in a long time and thanks for giving me more excuses to hoard all the gizmos I do!
Awesome, glad I can enable more hoarding 😂
Any vibrators🤷♂️
What a great video and a brilliant little channel this is. This is exactly what this hobby is about, having an idea and testing stuff out.
Right on
"little channel"? Guy has got almost 200k subscribers.
😆
@@User-jr7vf yeah but some 200k sub channels might have a whole staff and a studio, sponsors or what have you. This is still just a dude and his gear.
It doesn't matter that you're not an expert. You're doing a great job. You can also see that you are having fun. You also explain everything clearly. For me one of the best channels if you love technology. Thanks for that :)
The frequency information comes from a SatNOGS forum thread where someone spotted a signal at that frequency when looking for the older DPRK satellite, the KMS-4. As far as I know that has never been confirmed to be from KMS-4 or even come from a satellite at all. The KMS satellites are also said to have X-band hardware, meaning downlink frequency around 8 GHz, possibly with a directional antenna only transmitting when in sight of a ground station.
You can receive modern satellites in the 466 MHz band, it's used by weather satellites for negotiating with ground-based sensors. The MetOp-B and SARAL satellites transmit a very narrow signal at 465.988 MHz, while the ARGOS-4/Gazelle and OceanSat-3 satellites use a new downlink type on 466 MHz that's over 2 MHz wide, you would need to use a sample rate of at least 4 MHz to clearly see it against the interference.
Interesting, I didn't realize there were some active downlinks on 466! I'm definitely still a beginner with a lot of these systems. I also haven't gotten into X-band yet, mostly because I can't find any hardware that will handle it. I'm hoping if this thing is active that someone will figure out the frequency, even if they can't decode any of the data.
You guys rock ✊️😎
as satellite expert...they use Xband , its simple for them to use and try add s-band ...i find lnb with both x and s band lnb but it requires big dish
I think X-Band is higher than 8ghz, closer to 9-10 isn't it?
@@Vostok7789 depending on the definition you use it can be anywhere between like (6) 7 to 11 GHz, in terms of satellite reception "X-band" usually means 7-10, with most satellites being between 7-9
This is one of the craziest videos I've ever seen. Two cat scans and a North Korean spy satellite investigation?
All this needs is a laptop covered in snow and a giant Hogwash sign... wait...
OH MY GAWD!!!
Comedy gold!
Peter.
In 1957 I listened to Sputnik on 20 MHz using a Hallicrafters receiver made in the 1930s. :^)
Very cool sir!
Great !!! Typical set up, with the Hallicrafters...👍
Do you remember the model ?
@@jplacido9999 It was a Sky Buddy S-19 just like shown in this YT vid: *Hallicrafters S 19R Sky Buddy Communication Receiver* th-cam.com/video/lUldl2QJ2sY/w-d-xo.html
Cat polarity is crucial to the success of any radio activity.
Edit: I've heard a few people mention that they assume that the NK satellite will only transmit as it's going over NK
A few people who live closer have supposedly checked that, with no results.
It is very likely that NK uses the latest technology from mobile phone providers, whose coverage area can be adjusted to the nearest centimetre.
@@rudolfglaser9664 1) that technology doesn't exist. 2) if it did, NK wouldn't have it.
@@tomkandy yea this. they are basically stuck about 20 years behind everyone else as far as tech goes. they couldnt even get the first 2 sats into space, what makes you think they have centimeter accurate tunable radio tech?
@@IndianaDipper194 Somebody out there that can do this may have an interest in spooking the US with NK as proxy, and they may like to help NK.
You should be able to pick it up at 468.738 MHz using basic FM modulation. Use Orbitron or similar to predict orbit path. It's in LEO so you will need to point the antenna and move it as it moves across the sky. I've never done this manually but am amazed at seeing some of your past results. I used to downlink from foreign remote sensing satellites every day for work, but I had a multi-million dollar ground station at my disposal and the antenna tracked satellites automatically.
Damn bro, I just made a hot pocket and dropped it. I need to do something with my life.
I couldn't see anything at 468.738, I'm not sure if it's actually transmitting there or not.
Are you saying you can confirm it sends?
I know that phone hand motion! Map Accuracy was low, calibration needed, lol!
I'm glad I found your channel, great stuff!
If no one in modern society can remember old tech, it could be considered still viable...
Channels like yours always fascinated me. you're doing in your garage what otherwise is only done in million dollar projects and companies. it reminds me of the "old youtube". I'm sure many here remember it, where half the content was cat videos and the other half was videos by tech enthusiasts. I hope your channel will continue to do well!
Nice, here some date you can use. Frequencies:
Downlink frequency on 27 MHz Downlink frequency on 470 MHz (470,028Hmz) UHF uplink frequency unknown Downlink frequency on 470 MHz, UHF uplink frequency unknown X-band downlink frequency unknown
Do you have a source for that? I've seen those used for some of the earlier satellites that just played music, but I haven't seen confirmation of any frequencies for this one.
AO-7 is still operational for more that 40years
norad=58400 google search and the second result it has info on the satellite i have tried to link it a few times but it keeps getting deleted people are trying to pull data from it
@@saveitforparts
It seams bogus....27 MHz....?!!!! 😂😂
@@jplacido9999 Its true, I wouldn't have chosen that band either, but certainly not nonsense and not the first time to!
4:40 Gotta love that magnetometer calibration wave.
Lol
I appreciate the time you spent on this en-devour. Keep up the strong work.
I'm about to watch but I had to say that I'm SUPER HAPPY that you did this! When I first saw that they launched something I was wondering if you were going to try and "contact" it haha Cheers, Blessings, and please keep up the great videos!
Man I have been following your channel for a while now. Your content and your personallity is so heartwarming. Just wanted to say best wishes for you.
This channel is great. I can't believe it only has 150k subs. I love very video. I'm binging on the older content. So awesome.
To be fair, if I built a spy satellite for spying on the usa, i would probably set its transmitter to power down while outside the position my own country can send/receive radio to it. It would probably just target the area they wanted to spy on, take photos passively, then power back up once it was over korea and transmit down the data. Perhaps you should take a weekend vacation in south korea and bring your gear to the hotel. :)
A few people living closer to NK have listened for it and not found anything.
@@saveitforpartsoh well, it probably ran out of carrier pigeons then :D "carrier not found"
@@saveitforparts right, so maybe it's made to work only over dead center NK and not nearby?
man, I love that collection of dishes you have. Brilliant stuff.
SUBSCRIBED ! Already love your content, but this pipped it - cant wait for the updates !!!
Just a nice video as always. Its important to show stuff like this too. Not only the super flashy "OMG look what i can do vids". So often its much more to learn from a nagativ result than a postive one. Keep you reat content going! THX!
BTW, ham radio transmissions are NOT in the 460+ MHz range. There are some in the 430-440+ MHz but there wouldn't be any interference between the two ranges unless the North Koreans are using over the counter Chinese radios which are pretty dirty.
Love the humor! Great channel, keep being you!!
As soon as I heard about the NK satellite your channel was the 1st thing I thought to check! Thanks for the update
Another viewer actually asked me about it, so that inspired me to do a video :-)
I rarely ever understand much of what you're saying, but I really enjoy watching your videos. Find that stuff that's out there!
You sir have some fascinating topics, very much appreciated 🤙
This type of ad-hoc video are / was awesome.
Have you tried a circular polarized "Egg Beater" antenna? Not as much gain as a yagi but doesn't require aiming. You could also get rigs for ham radio that enable people to control the antenna as the satellite arcs through the sky. Since there are many amateur satellites and repeaters on 400Mhz, did you try your methods on those known signals. For example SO50 and the ISS come to mind as satilite repeaters that are relatively easy to work. I had success working satellites with a Arrow yagi antenna making some contacts with a 5w Yaesu HT. Even once receiving a beacon from a palm sized cube sat. Since many satellites tumble through space, the polarization of the antenna is sometimes continuously changing as it arcs across the sky. Meaning with an antenna like a yagi, you have to rotate the antenna to get optimal signal.
Also the mode of satellite matters too.Not everything is FM. I would venture to guess any government satellite is running some sort of encrypted digital format in a much a higher frequency band to pass more data. However, it's possible the satilite might have a back-up 400MHz transceiver on board. Some satellites will have a separate transmitter to transmit the health of the systems on board.
For those in the USA who want to work satellites, all you need a Technician class Amateur radio license, a 2m/70cm FM HT with two VFOs (or two radios to receive and transmit), and a UHF/VHF yagi. While Arrow makes one that is ready to go, there are plans to make them out of a tape measure and PVC pipe. The ISS is by far the easiest to receive and hit. It's possible to receive it with just stock antenna. Some people are far more invested in the hobby with radios like the Icom 9700 controlled by software that also tracks their antenna.
I LOVE HOW YOU ARE EXPLAING THIS STUFF
thanks for the video! that was really interesting and thanks for the shout-out!
Sure thing! I don't have time to try everyone's suggestions, but I liked yours and wanted to give it a try. Even if I didn't find much, apparently people think this video is entertaining.
was waiting for this vid as soon as I heard about their new sat
I really appreciate you documenting the less-successful ventures along with the great successes!
Love this channel, great video
Love your videos keep posting 🎊
You put up solid videos! Keep it up!
Oh that was cool! Was hoping we'd hear something
Hey been watching your channel for awhile now, just wondering if you live in MN? I’m also a Minnesotan, just noticed the shirt is all lol love the content my friend
Yep, I'm in St. Paul.
great! this was the last straw to join the patreon. looking forward to more
I am currently listening to the South Korean shortwave radio on 3955 kHz. There was just a report about the North Korean spy satellite; it seems to have already transmitted images. According to the information, some additional tests are still required, and then it will officially become operational.
thx for the content. we love it!
Good video.
Thank You,
JR
Very cool and enternatining. Cat scans are a must
It's to bad you don't have the radar dome up. You coulda been protected from the weather.
Gotta get that assembled next spring!
This guys wholesomeness ranks right up there with Steve Irwin and Brian Barcyzk. Guard this man!!!
It can't possibly be dead. North Korea published news that Dear Leader was given photographs that the satellite had taken, and they would never lie to us.
The real question is would the engineers lie to the great leader
@@personzorz They probably printed out something from Google Maps in order to live another day.
Well, that is quite correct, despite of sarcasm. Their typical propaganda style is “tell the good news, be mute about bad ones. But typically they don’t explicitly lie about things never happened.
Latest message was that a military base at Hawaii and the White House in DC was photographed by this satellite, but no pictures so far. But to make statements like this without showing any pictures is a bit lame imo.
@@MacIn173 "But typically they don’t explicitly lie about things never happened." -- Isn't there a museum in North Korea showing the first North Korean on the moon and a Mercedes car as an example of the achievements of North Korean industry? I think I saw pictures of these things in National Geographic a long time ago.
Leading with a disclaimer and catibrating antennas, I can relate.
4:13 I think your earlier comment about "old School" is applicable here. What is that in terms of modern day satellite stuff?
Love your satellite videos thumbs up
experience, it's what’s you get when you don't get what you want! Great stuff as always 73.
Really interesting. How long has it been up, I hadn't heard about it. Also I'm in MI and we're having snow come in now too, makes me have to motivate myself more to go out and listen to satellites 😂
No Effort November.
Fair :-D
Commenting to help the Algorithm! Your videos (Even the adhoc ones) have greatly improved. I'm glad your channel is getting the attention it deserves.
great episode
interesting !
its good to have independent reporting on these matters.
The cat polarity test 😂, I love this channel.
from 155k subs a week ago to 158k now.
Congratulations sir!
Thanks! I'm not sure how that keeps happenings, but I guess I'll just keep doing whatever I'm doing :-P
It stopped sending signal when the string between the steel cans broke.
this is awesome man!
What a fun and positive guy you are!
Save it for parts I subscribed to other channels and found your through them You make cool vidz
if it falls out of orbit make sure to save it for parts, nice video :)
Excellent channel. Thank You ! BTW: The bioluminescence of the larvae of fireflies is circularly polarized ! 🙂 !
This man is the type of person that when the zombie apocalypse happens, he is still able to contact army high command of a country on the otherside of the world
An even slightly smart implementation of a spysat DOWNLINK would only be enabled when passing over a friendly ground station.
1:43 as usual I have a ton of jobs to finish, but here I am watching a dude trying to pick up a North Korean spy satellite's signal 🤣
There are still some active downlinks in the 460s, you just need the bandwidth sample to get above noise floor.
But I have noticed a carrier with no (discernible to me) data at 1417.6 (best guess at an average with unknown doppler shift) mega hurtings, which I thought was guarded for RA.
My listening gear is all scrap/salvage/borrowed or Strategically Transferred Equipment (you know,) to Alternative Location. I imagine that you can relate.
But I'm IVO a certain SE US port city so maybe that's why I got something. Just odd the band and the timing.
You could try the cold war military HF bands USB and LSB Russian or chinese bands ?
Can you upload a self destruct instruction to the satellite?
I love the CAT scans!
Your pre-amp is probably getting overloaded from out of band signals. The SDR can get overloaded by itself. Bandpass (or Bandstop) filter can take care of a lot of overload and intermodulation problems. Plenty of filter designs on the Interwebs.
no production value, everything is probably terrible and this channel is awesome!
I noticed the copy of "Atlas Obscura" on your bookshelf.
"Always check the polarity of your cat..." OMG I'm dying...
To me all sounds and looks okay. You did great.
Great Video.
Donny and Fluff are AWESOME!!!!!
6:48 insert any MadTV - Stuart “look what I can do!” Clip here 😂😂😂
Brother,I love all your videos,
This is the type of videos I love
2:43 new, very niche meme
My guess is North Korean hasn't powered up the onboard radio equipment just yet. That could be why you didn't get a signal from it. Generally the idea is, satellites remain "dormant" until they reach their intended operating altitude to save onboard battery power. It generally takes up more power to operate the satellite's thrusters than it does the radio equipment.
Your polarized humor was catastrophic 😂
The technology acquisition system for the Norks is probably less efficient than driving to Axman on a Saturday afternoon. Nice touch with the cat polarity stuff. When the humorless men in sunglasses show up for a little chat with you they might twitch slightly in their equivalent of a beaming smile.
thank you!
I enjoyed the results of your cat scan
Thank you!
just found this video in a recommendation. Thattle be an instant subscribe from me! super interesting. i miss my rtl-sdr. need to get a new one and get back into this stuff
Can they turn it on and off? Could it be a photo sat?
It's a sucessful video as it demonstrates how to test and verify yourself random online claims and perhaps discover something new that is of use to the rest of the community :)
ah yes, let me just pull out my 9ft wide radio dish to fact check this comment
Great efforts Brother, it shows how hard and time consuming it is to scan to unknown frequencies.
how do you spot/ track these North Korean satellites ?
73
Ive read that December 1st is when the satellite begins its mission in orbit, maybe this is wrong but I remember seeing it somewhere on youtube
I saw that as well, I also saw reports that it's supposedly sending down pictures already. Hard to know what's accurate when it's only one source!
@@saveitforparts something tells me that North Korea was probably testing the satellite’s systems to make sure that everything works as it supposed to before the satellite’s mission begins on December 1st.
Before you ask how did I know that, I follow the James Webb Telescope on twitter when NASA and ESA, and the Canadian Space Agency were testing the space telescope’s systems after it was inserted into its planned halo orbit
A fellow gopher!!! that was fun to see!
Interesting - thanks.
How is that satelite-tracking-gyro-thing coming along, mr Parts? :)
Still on the to-do list :-P
is it possible, that the Satellite is receiving in its current state and only sending if asked to?
Should be possible, right?
edit: and your videos are ALWAYS interesting, don't worry about that :)
That's possible, or it might only transmit when it's over NK. A few hobbyists who live closer to Korea have also looked and not found anything. Hard to say for sure though!
Your "cold" is just the first step of Comrade Kims Revenge😂
Malligyong-1 (Korean: 만리경-1; Hanja: 萬里鏡-1) is actually pronounced as "mahn-lee-gyong".
Composed of three syllables, the name is a portmanteau of the word "mahn-lee" meaning "ten thousand miles" and the word "mahn-won-gyong" meaning "telescope".
