A magnificent accomplishment. Now, if only you'd been content to stop there. Building that much bigger Yagi antenna and suspending it from a big white balloon sure seemed like a good idea at the time.........
It's still a great way to loft a Yagi, but not everybody can afford a balloon. Using a giant box kite would be more cost-efficient for a non-state actor.
There is no point in having the antenna very high up. As long as you have line of sight to the satellite and not much local noise from electronics, it will be fine near ground level.

Cool, thank you! I'm sure I could have recorded more and caught longer conversations. I've heard that a lot of the users are truck drivers, so it makes sense to hear them talking about cargo and routes.
@@saveitforpartsyes, truck drivers, farmers and illegal loggers in Amazon forest are the regular users in Brazil. But the Federal Police, with help of US govnmt, track and arrest then. FARC and a famous brazilian drug dealer called Fernandinho Beira Mar used this Sat, called here "Bolinha" (little ball), until his arrest in 2001. Other major criminal organizations (PCC) used until the arrests became recurrents by signal triangulation.
HI, I used to work FLTSAT for the USAF in the late 1980s. I think you should look into "circular Polarization" for your receive antenna. I believe you want LEFT-HAND-cirlc-polarization (LHCP) for receive (RHCP for TX) . Also, the biggest problem the Pirates make is each one takes power from the tansmitter on the satellite. The battery can only kick out a certain power per day....now it's DECADES later so the battery is about 50% what it used to be.....Each Pirate takes a chunk of satellite power.....and these satties are what we call "bent-pipe" repeaters....the more power you pump in, the more power it pumps out...further draining the battery. ( I worked with the agency that was always highly concerned with "power balancing" across users.).......OK, now for my illegal satty story story.....I once called CQ over a Top Secret Gov't satellite network.....I was told to never do it again. SO....I love your channel...let me know if I can help in any way with my satty experience.....Ka1igc
Very cool, and good info thanks! I'd like to do a follow-up video when I have time and attention for it (LOTs of projects on the pile), so those would be some cool details to include.
Working in N6 for the Navy I could never figure out why SATOPS was always so frustratingly anal about power balancing. I had no idea they just wanted to keep us from draining the sats batteries, that's hilarious. Thank you for this!
Did you end up off freq by accident? Or did they put that hidden sat system in the ham band? That is funny. When I used to work for the radio systems companies I would find the unused antennas on the tower and take a suitcase radio with me. Plug in the ant analyzer and figure out what band they were in on the ant's on top the tower. I would find one I could use and operate during lunch. This one tower was 350 free standing over hilltop. Perfect. It was always amazing what you could get into on 1/4 or one watt power. I did a lot of QSO from places like that.
"I once called CQ over a Top Secret Gov't satellite network" Ah, no harm no foul. My uncle worked at a remote station for the Air Force and used to do a trick where he'd call the next station over and ask nicely for a patch into the next one from there, and so on, until he'd circled the continent and gotten back to where he started, at which point the duty desk would call over the PA that he had an incoming call, only to be connected to himself.
10,000 points to you. A lesson for anyone overthinking anything when you can reuse, repurpose and reinvent useful things out of an antenna you already had, a $1 adapter and scrap.
A good friend of mine was in 1/505th 82nd ABN back in the 80s. They were all out in the field at Ft Bragg and got together with the commo guys who were able to use their satcom uplink to get into the PSTN, whereby they proceeded to order a huge stack of pizzas from Domino's. They gave the delivery guy instructions like, "Take the Post Road hardball until it disappears in the sand and we'll meet you there..." The guy shows up and all these grunts with green faces, foliage in their helmets, and M16s emerge from the darkness to pay for the pizza and carry it back to the Assembly Area. I thought this was a pretty cool use of resources.
I’ve been tracking these for a few years in the U.K. with mostly rabbit ears and a Tri band UV-5R or Yupiteru. A 1/4 wave ground plane antenna works well too. The common frequencies seem to be between 255 and 262, usually Brazilian Portuguese language or Russian. Comedy Radio from Russia is sometimes very clear, I’ve also heard Mosque broadcasts and even Karaoke microphones! It’s an interesting section of the radio spectrum. Thanks for the video 👍🏼
In Brazil those satellites are nicknamed "bolinha" (little ball) and they were heavily used, today because of Internet and cell phones I think they were not much used. But I saw news on TV a few years ago about Federal Police apprehend the equipment of some of those pirates.
@@KlodFather 1. there is a fine 2. putting people in jail for doing that would benefit no one 3. Brazilian Federal Police has more to do than to protect unused obsolete USA military unencoded bad designed satellites that could even be used by the enemy. Satellites from the 60's that are not decommissioned because it would cost more to do so than to let they rotten in space.
@@Nomamegoogle - They should be more harsh with them. Confiscate the radios or better yet whatever has the radio in it. House or vehicle. Make it hard. Problems go away when they take your stuff and throw it all out in the street and board the place up or burn it down. These guys are causing international defence problems with their disregard for the law.
8:09 You are picking up local FM stations because RTL-SDRs have bad image rejection capability, I would recommend adding a FM broadcast bandstop filter to attenuate these signals
That or a harmonic of the original frequency. Or possibly the result of 2 frequencies mixing in an imperfect RF system. After a few decades of working on antenna systems, I can confidently say RF can be pretty "black magic" outside of the mathematical theory world sometimes.
@@pileofstuff - We engineers used to say, 50% science and 50% witchcraft. Its really true. You should have seen some of the shit we saw and lived through LOL STuff from science fiction movies LOL
@@pileofstuff For something that only have about 48dB of in-band dynamic range, it's more likely to be image frequency / aliasing (especially because RTL-SDRs use direct conversion & doesn't have a great IF filter)
If you question why they didn't put any kind of access control on those early repeater satellites Consider that prototype repeater satellites became unusable less than a month after launch because clock-based access codes got out of sync
@@yoeyyoey8937 ....have you ever tried to keep 2 clocks sync'd??? this is why they came up with the atomic clocks that are small enough to orbit.....that is the ONLY way.....there are a gagillion factors but...when you consider that there are as many nano seconds in one second as there are seconds in 32 years and you are trying to sync to LESS that THAT......yeah....
@@Name-nw9uj ...they didnt have accurate and small enough atomic clocks.....the new quantum technology will make all that look like sticks and stones....
Back some 65 years ago I used to sit in front of the family radio and turn the band to try and listen to whatever I could pick up. I would sit there for hours trying to hear something from someone somewhere on Earth. I don't remember specifics, but the mind of a 10-year-old can create many things that could happen and hope to find one of them. It was quite fun. Not sure what my parents thought of me with my ear to the speaker while turning the dial. BTW, this was before TV in our house...and many other houses too.
I used to do it with my crystal radio built on my Radio Shack 30-in-1 electronic project kit...so cool. Plus, I could listen on my little earphone all night if I wanted to!
as a kid i had an old radio from my grandma (one of these big boxes). I changed the radio bulbs (vacuum tubes) with some i found on scrap-radios and one time i even could hear the police radio lol)
On my childhood FM radio you could puuuuuush the dial off the bottom end you could pick up a strange pulsing transmission, some kind of data transmission I guess.
I'm an absolute turnip - I don't know anything about this very interesting topic - but you had me at space pirates, and I really enjoyed your attitude and presentation - ty!
The voices at around 7:38 are in Portuguese. The lady is saying "stay tuned ok, stay on this ??" "If you need anything call me on this, or I'll be listening in on the other one too" (I would imagine they're talking about frequencies). At 9:06, again Brazilian portuguese saying: "How is it over there? Talk to us. We just loaded the truck now". The next transmission I can't make out other than the word "carga" (cargo, or load in English).
5:04 it is recommended to get the antenna off the ground for proper swr/resonance measurement. all the stray capacitance of the floor will detune your antenna by quite a bit. although it's not that critical for rx only, i would suggest you redo the measurement while the antenna is on its tripod.
This is cool! I need a crash course on frequencies and radio satellites though. Older analog communication would be a pretty useful skill at times I bet
I wonder if the age of the components has caused any frequency drift in the repeaters. Regardless, I love that these 40+ year old satellites are still functioning and still getting used, even if for unauthorized purposes. A testament to engineers who designed and built the originals, glad they're not just space junk.
As it appeared in the video, the sats were actually still in service, so even without the pirates, they would not be space junk yet. But with increasing user count and decreasing battery life, they may end up as junk sooner. But surely is more fun to see this tech used by a broader audience than intended.
Well, its not all that hard, AO-7 is a ham radio satellite that was launched in 1974, and remained working until a battery failure in 1981 when it went quiet. It was heard again in 2002, when the batteries finally went "open ckt" and the equipment started operation again using only solar power. It would reset when in darkness and restart when it was getting enough light. Other than the batteries, the thing is about ready for its 50'th birthday next year, and was built by amateur (ham) radio operators on a very thin budget.
It has been a few decades from my Electronics Technician Training. That said, Check the length of the directors ( preceding the antenna ) and distance apart as well as the reflector ( after the antenna ) for the correct parts of the frequencies. They looked to not be like Yagi where the reflector is larger and the preceding ( you have 3 so front looking over half the length, next two almost the same, but shorter ). You may also want to get some more wood and cut them in half, get some wire to connect the antenna to the middle directors in a cross pattern ( when held so the antenna is pointing right, bars up, top to bottom to top antenna segments and opposite for the pointing down antenna ). Good luck hunting down the Space Pirates.
If you find any AM signals in those transponders, they are military ATC in the uplink bands (~300MHz) that are probably asigned without knowledge of the frequencies also being allocated for satellite uplinks. We do hear them from time to time.
I listening to many Brazilians and Russians, but there is also a small group of Italians, not all of them in Italy who have been making themselves heard for over 15 years, sometimes more, sometimes less, but Brazilians and Russians are on the increase, thanks also to Chinese portable and vehicular radios that have invaded the market, capable of transmitting on the rising frequency, pleasant contacts from Europe have been felt with the Russians in English, always kind and helpful, however there is no way with the Brazilians who insult immediately heavily for no reason.Ciao
The U.S. Govt legit SATcom stuff in the 250s these days are mostly secure data links. There's definitely still some secure & plain-voice USG Tacsat comms in the 260s -- some of it important stuff, But a lot of the USG Tacsat has migrated to MUOS CDMA with downlinks in the upper 300MHz area. Really annoying to hear the pirates for those of us that used to have to submit requests for UHf SATCOM transponder access back in the day & get in trouble if we used to much uplink power, etc.
WHy did it matter if you used a little too much power on uplink? I realize that you don't need a kw to access it, but enough juice to make a solid entry into the system. What kind of karens run that system anyway?
@@KlodFather As available power is shared across users, normally you uplink enough power so that the downlink power is enough to be received. If you uplink more power, the other downlinks will suffer, dependant on sat power budget. A major sat system I worked with some 40 years ago, had automatic individual and total uplink power adjustment. All users of the system had their uplinks controlled in this way.
Ha. The chopped up tape measure segments are also used for direction finders when fox hunting for transmitters. You can go rung through the undergrowth without the risk of being impaled by a ridgid element. Lighter also.
Former US Navy Radioman here. I went to school for this system in 1977 and used it at sea on a system called NAVMACS. It's amazing those transponders are still operational. en.wikipedia.org/wiki/Fleet_Satellite_Communications_System
This is something I have been trying do with similar tech, quite a few Zombie Sats out there with no encryption on them some still with power at times (depending what and where). This content if fantastic, Love the back stories on the history of the tech the most. Thanks for the content :)
A log periodic or yagi log periodic would give you the wider band. Your yagi is really on the low side gain wise. Down in the equator area, they will not need such high gain antennas. The voice you heard sounded like Portuguese which while closer to Spanish can sound a bit like Russian if you are not familiar with the two languages.
And I would have recognized Russian as I worked with a bunch of Russian engineers and started to learn the language from them. Its complex as hell but full of nuance and surprises. These clowns on that channel sound like a bunch of CB trash and should be eliminated. Shutting off the satelite for a year or two should clear the board. THe radios would fall out of use quickly when the system goes dark.
I heard almost nothing on that frequency all day when I was messing with this. I had read it was one of the more popular ones, but I guess I just picked a quiet day to listen!
I heard the female say ‘obrigado’, which is Portuguese for ‘thank you’. Cool video and concept, cheers for sharing! PS, your man-cave looks like a sweet shop to me, lol 👌
Hahahahaaaa your neighbor just freaking out watching you like, “ohh shit here he goes again” keeps watching as the equipment in your yard starts moving ”what the hell is that thing. Honey come look at this shit, our neighbors setting up some experiment.” 😂
NPR on 271 MHz is very common you will pick up FM local transmissions on 271 Mhz and even sometimes you will pickup shortwave transmissions, it is just a harmonic frequency. That is why you typically want to use an FM bandpass filter. IDEALLY you want to use a band pass filter that filters out everything except the band you are interested in, in this case 270mhz
I'm very familiar with Space Pirates (otherwise known as SPRT) Honestly it's pretty easy handling their planetary bases and cargo ships, just need to pummel their pre-warfare weaponry with autocannons & Artillery, disable their AI, and then boom! You've got some new components and such. (If you are curious, this is referencing Space Engineers. That is the joke)
Most of those transmissions in portuguese that you've presented I assume they were made by truckers, they use some frequencies as a "team speak". And maybe... Sometimes Portuguese can be a little tricky and sound a bit Russian, phonetics are kinda similar
Hi there, the main "users" on the military Fleetcom VHF frequencies around 250 ... 260 MHz will be stations from Brazil. Here in the Netherlands they are easy to monitor, with a Discone antenna, or even a "vertical" for 2m//70cm.
Oh so this is the video where you're haunting pirates. I am an SWL from Italy, I use a superclassic omni Diamond X300 on a Yaesu FT-7800 vhf/uhf radio and I can normally pick up lots of Brazilians pirates, sometimes Russians but mostly people from Brazil. Yagi on VHF is good if you want to get a point-to-point connection, otherwise a good old simple J-pole will march quite nicely (if you only want to catch waves without considering the ROS, so not transmitting and say goodbye to the radio). I made one from various copper scraps and I can get ships and planes from 105 MHz to the 140 MHz. Though VHF are quite keen to pick up lot of noise, sometimes it's crystal clear, but I live 50 mts far from the Adriatic sea... The idea of using a PTZ cam as a rotor is just awesome!
Cool, thanks for the info! I'm always learning more about antennas, I have an amateur license and have read some of the theory books, but it always makes more sense to me once I've actually tried it for real.
@@saveitforparts Ah, nice! I'm waiting for my license too. For now, '73 here, maybe one day we can try to catch on air, when I'll have some spare time to setup a DX (I sell marine engines... funny how we have common passions :D )
came to this channel originally for the boat content, but this stuff is cool to me even if i have no clue how it works. neat to see a channel out of the city i live in.
I've not tested the metrics in any real comparative detail or to any standards other than the nanovna, though I'm still amazed how well my 450MHz yagi worked and works only using wooden rod with aluminum duct tape wrapping for the reflecting and directing elements. I invested in a 3D printer pen to make the mounts more adjustable for finer tuning. I never got around to making with the plastic knurled thumb screws or 3D printing, though did order and have most the parts I need if not all.
By the way, I thoroughly love the channel! I also picked up satellite signals at these frequencies shown in your video, but with my biconical antenna, it was too faint for the descriminator. Just heard extremely spotty voice. Going to build a directional.
Sat comms were my favorite back in my marine days. We didn't have a geosyncronus satelite over head for the man portable kits I used. Instead I had to kinda guess where tf it was in the sky, aim the antenna at it, and see if it would transmit. Kind of a pain, but I liked them bc the voice comms were always crystal clear. But for reliability it was hard to beat the old HF radio with a field expedient antenna.
@@saveitforparts Encryption is a whole other thing. Stock they are unencrypted til you load crypto. We would use unenceypted chanells to talk to civilian run range control to let them know when we were going live, when we were done shooting, how many marines were on range, etc. Since you are a radio guy, you prob already know, but if u don't I suggest looking into omnidirectional field expedient antennas. All you need is some copper wire cut to the right length for the frequency, a means of holding that copper wire off the ground. You can get comms with anyone using that same freq within 350 mile radius. Field expedients were only workable with HF radios due to the length ratios required to cut the copper wire. (The length of the cut has a certain ratio to go with the freq, but I have long forgotten the tables for that) Not all info I'm giving u here is gonna be 100% spot on (I've been out for ten years) so I'm just goin off of memories. Hope this will maybe give u an idea for a video you can do.
They are speaking in Brazilian Portuguese, the woman tells him: "hide the cargo and stay alert. She will be monitoring this one and "the another one". I'll let you know if anything happens. The man just responds something that means "Ok, thank you"." She is probably referring to the frequencies of the police, military, etc. and she will let he know if she hears anything. In the second transmission, he calls someone and says he has just loaded the tractor
Lol man I could uae some friends like you! I have always been the "oddball maker"/"horder of electronics etc" one of my groups. The biggest problem with being interested in so many different things that require a good bit of experience and research to understand, is that you are lucky to meet anyone in person that is into even just one of those many things. It's ts a damn miracle to meet someone that is into more than one of them....at least where I have lived. Finding the time to do all the stuff you want to is another big problem with it😁 Anyway, fun times! Keep it up man!
7:42 it looks like portuguese for me they're saying something like: "sera que ele chegou na cidade carregado ou (dont undertand the rest)?" translation is "did he arrive in the city loaded or (i cant undertand the rest)?" probaly a truck driver from brazil (my country yay) and the woman said: "(dont undertand) so fica ligado ta? fica nessa rua ai" "stay alert ok? stay in this road" and the guy said: "positivo, positivo" its something like "ok, ok" in english and the girl said: "ok qualquer coisa so me chama aqui nelson, vou ficar ouvindo ela e a outra, ta?" translation: "ok anything just call me here nelson, Ill be listening to her and the other one, ok?" and the guy said: "beleza, joia" translation: "ok, thankyou" (not literal translation, but he means something like this)
Hello Friend! Nice video! I speak native Portuguese, and I can sure tell you that all conversations are from Brazil. You are correct that most communications are from truck drivers and, sometimes, from farmers in the middle of nowhere. I can try to translate what they speak if you want.

After that things settle down and people get serious. When engineers make mistakes in products, people get hurt. Common sense is not out there and the guy with the most papers on the wall is rarely the brightest bulb in the room. Facts.
If I may suggest, @7:30, when you located a pirate station, it will help the intelligibilty if you narrow your IF bandwidth, to cover the signal only. The reason your audio was "fuzzy" was that your BW is too wide.
I've been able to receive these with an rtl-sdr and an omni directional scanner antenna on my roof here in central california, surprisingly strong signal. Usually Brazilians? using these repeaters from what I can tell
In the twin cities there's MPR News at 91.1.The third harmonic of this would be on 273 MHz.... And there's KFAI on 90.3 MHz which would have it's third harmonic at 271 MHz but that's not MPR or NPR. Probably one of these signal is loud enough for you that the filtering after the mixer in the R820T tuner of the rtlsdr dongle can't knock it down below your noise floor at ~270 MHz. And then there's just some local clock error in freq that shifts it there.
Just a question, if he was picking up the third harmonic of an FM station, wouldn't the signal stay somewhat constant if he changed the direction of the antenna? Wouldn't the harmonic be coming into the antenna/system from the side and not from the direction the yagi is pointed? I hope I asked that correctly. Thank you.
I was always wondering why i pick up FM radio signals with my analog 90's TV 😁(i use it for gaming).So it is a kind of unwanted FM transmission artifact.
It's crazy... I built a rabbit ear yagi almost the same way about 6 years ago. only thing I did different was use copper wire for the other elements. worked like a dream on 2 meters.

Best not to fine tune antennas while they're resting on the floor. You might get away with it, but still... Best to have them at least a little bit further away from things.

the last one is talking about where someone is going, and asking why prob he changed his route, and he tells why he changed
Cool, thank you! I'm sure I could have recorded more and caught longer conversations. I've heard that a lot of the users are truck drivers, so it makes sense to hear them talking about cargo and routes.
It is Brazilian Portuguese the language.
@@saveitforpartsyes, truck drivers, farmers and illegal loggers in Amazon forest are the regular users in Brazil. But the Federal Police, with help of US govnmt, track and arrest then. FARC and a famous brazilian drug dealer called Fernandinho Beira Mar used this Sat, called here "Bolinha" (little ball), until his arrest in 2001. Other major criminal organizations (PCC) used until the arrests became recurrents by signal triangulation.

HI, I used to work FLTSAT for the USAF in the late 1980s. I think you should look into "circular Polarization" for your receive antenna. I believe you want LEFT-HAND-cirlc-polarization (LHCP) for receive (RHCP for TX) . Also, the biggest problem the Pirates make is each one takes power from the tansmitter on the satellite. The battery can only kick out a certain power per day....now it's DECADES later so the battery is about 50% what it used to be.....Each Pirate takes a chunk of satellite power.....and these satties are what we call "bent-pipe" repeaters....the more power you pump in, the more power it pumps out...further draining the battery. ( I worked with the agency that was always highly concerned with "power balancing" across users.).......OK, now for my illegal satty story story.....I once called CQ over a Top Secret Gov't satellite network.....I was told to never do it again. SO....I love your channel...let me know if I can help in any way with my satty experience.....Ka1igc
Very cool, and good info thanks! I'd like to do a follow-up video when I have time and attention for it (LOTs of projects on the pile), so those would be some cool details to include.
Working in N6 for the Navy I could never figure out why SATOPS was always so frustratingly anal about power balancing. I had no idea they just wanted to keep us from draining the sats batteries, that's hilarious. Thank you for this!
Did you end up off freq by accident? Or did they put that hidden sat system in the ham band? That is funny. When I used to work for the radio systems companies I would find the unused antennas on the tower and take a suitcase radio with me. Plug in the ant analyzer and figure out what band they were in on the ant's on top the tower. I would find one I could use and operate during lunch. This one tower was 350 free standing over hilltop. Perfect. It was always amazing what you could get into on 1/4 or one watt power. I did a lot of QSO from places like that.
"I once called CQ over a Top Secret Gov't satellite network"
Ah, no harm no foul. My uncle worked at a remote station for the Air Force and used to do a trick where he'd call the next station over and ask nicely for a patch into the next one from there, and so on, until he'd circled the continent and gotten back to where he started, at which point the duty desk would call over the PA that he had an incoming call, only to be connected to himself.

That is unspeakably cool! Never would’ve expected pirate radio to exist in space.
10,000 points to you. A lesson for anyone overthinking anything when you can reuse, repurpose and reinvent useful things out of an antenna you already had, a $1 adapter and scrap.
A good friend of mine was in 1/505th 82nd ABN back in the 80s. They were all out in the field at Ft Bragg and got together with the commo guys who were able to use their satcom uplink to get into the PSTN, whereby they proceeded to order a huge stack of pizzas from Domino's. They gave the delivery guy instructions like, "Take the Post Road hardball until it disappears in the sand and we'll meet you there..." The guy shows up and all these grunts with green faces, foliage in their helmets, and M16s emerge from the darkness to pay for the pizza and carry it back to the Assembly Area. I thought this was a pretty cool use of resources.
Best use of tax dollars in a long time.
I’ve been tracking these for a few years in the U.K. with mostly rabbit ears and a Tri band UV-5R or Yupiteru. A 1/4 wave ground plane antenna works well too.
The common frequencies seem to be between 255 and 262, usually Brazilian Portuguese language or Russian. Comedy Radio from Russia is sometimes very clear, I’ve also heard Mosque broadcasts and even Karaoke microphones!
It’s an interesting section of the radio spectrum.
Thanks for the video 👍🏼
Brasileiros!!
I've always wanted to have some fun getting into a microphone or shop P.A circuit 😂
Mosques? Disgusting
Some drunk singing karaoke unaware they are being broadcasted over a vast area 🤣
uv52 is dual band
In Brazil those satellites are nicknamed "bolinha" (little ball) and they were heavily used, today because of Internet and cell phones I think they were not much used. But I saw news on TV a few years ago about Federal Police apprehend the equipment of some of those pirates.
If they confiscated all their radio gear no matter the band, it would deter them for a while. The punishment should be much more severe.
@@KlodFather 1. there is a fine 2. putting people in jail for doing that would benefit no one 3. Brazilian Federal Police has more to do than to protect unused obsolete USA military unencoded bad designed satellites that could even be used by the enemy. Satellites from the 60's that are not decommissioned because it would cost more to do so than to let they rotten in space.
@@KlodFather why?
Policia federal is like gestapo or stazi in Brazil
@@Nomamegoogle - They should be more harsh with them. Confiscate the radios or better yet whatever has the radio in it. House or vehicle. Make it hard. Problems go away when they take your stuff and throw it all out in the street and board the place up or burn it down. These guys are causing international defence problems with their disregard for the law.
8:09 You are picking up local FM stations because RTL-SDRs have bad image rejection capability, I would recommend adding a FM broadcast bandstop filter to attenuate these signals
That or a harmonic of the original frequency.
Or possibly the result of 2 frequencies mixing in an imperfect RF system.
After a few decades of working on antenna systems, I can confidently say RF can be pretty "black magic" outside of the mathematical theory world sometimes.

If you question why they didn't put any kind of access control on those early repeater satellites
Consider that prototype repeater satellites became unusable less than a month after launch because clock-based access codes got out of sync
did they not take time dilation into account?
How did they get out of sync?
@@yoeyyoey8937 ....have you ever tried to keep 2 clocks sync'd??? this is why they came up with the atomic clocks that are small enough to orbit.....that is the ONLY way.....there are a gagillion factors but...when you consider that there are as many nano seconds in one second as there are seconds in 32 years and you are trying to sync to LESS that THAT......yeah....

Back some 65 years ago I used to sit in front of the family radio and turn the band to try and listen to whatever I could pick up. I would sit there for hours trying to hear something from someone somewhere on Earth. I don't remember specifics, but the mind of a 10-year-old can create many things that could happen and hope to find one of them. It was quite fun. Not sure what my parents thought of me with my ear to the speaker while turning the dial. BTW, this was before TV in our house...and many other houses too.
I used to listen to shortwave radio at night when you could hear faint signals better. It's always interesting what's out there!
I used to do it with my crystal radio built on my Radio Shack 30-in-1 electronic project kit...so cool. Plus, I could listen on my little earphone all night if I wanted to!
I used to do the same. Simple things were the best things...
as a kid i had an old radio from my grandma (one of these big boxes). I changed the radio bulbs (vacuum tubes) with some i found on scrap-radios and one time i even could hear the police radio lol)
On my childhood FM radio you could puuuuuush the dial off the bottom end you could pick up a strange pulsing transmission, some kind of data transmission I guess.
I'm an absolute turnip - I don't know anything about this very interesting topic - but you had me at space pirates, and I really enjoyed your attitude and presentation - ty!
The voices at around 7:38 are in Portuguese. The lady is saying "stay tuned ok, stay on this ??" "If you need anything call me on this, or I'll be listening in on the other one too" (I would imagine they're talking about frequencies). At 9:06, again Brazilian portuguese saying: "How is it over there? Talk to us. We just loaded the truck now". The next transmission I can't make out other than the word "carga" (cargo, or load in English).
Yeah, I was gonna mention that sometimes Portuguese is mistaken for Russian, but clearly you beat me to it lol
I've been guilty of it before, tbh
o cara manja dos pt-br
This was mentioned in Tom Scott's latest newsletter. Very cool!
That's cool!
I found it from there too
5:04 it is recommended to get the antenna off the ground for proper swr/resonance measurement. all the stray capacitance of the floor will detune your antenna by quite a bit. although it's not that critical for rx only, i would suggest you redo the measurement while the antenna is on its tripod.
7:25 WOW! is Brazilian Portuguese hahaha, recently discoverd this channel and it's amazing, Keep up the great work buddy!! shout out from Brazil!
This is cool! I need a crash course on frequencies and radio satellites though. Older analog communication would be a pretty useful skill at times I bet
This video was amazing! Thanks for doing this intro to satellite pirate radio. The history of it is something I had never heard of.
I wonder if the age of the components has caused any frequency drift in the repeaters. Regardless, I love that these 40+ year old satellites are still functioning and still getting used, even if for unauthorized purposes. A testament to engineers who designed and built the originals, glad they're not just space junk.
As it appeared in the video, the sats were actually still in service, so even without the pirates, they would not be space junk yet. But with increasing user count and decreasing battery life, they may end up as junk sooner. But surely is more fun to see this tech used by a broader audience than intended.
Well, its not all that hard, AO-7 is a ham radio satellite that was launched in 1974, and remained working until a battery failure in 1981 when it went quiet. It was heard again in 2002, when the batteries finally went "open ckt" and the equipment started operation again using only solar power. It would reset when in darkness and restart when it was getting enough light. Other than the batteries, the thing is about ready for its 50'th birthday next year, and was built by amateur (ham) radio operators on a very thin budget.
@@arnoldgrubbs2005that's really cool to hear
It has been a few decades from my Electronics Technician Training. That said, Check the length of the directors ( preceding the antenna ) and distance apart as well as the reflector ( after the antenna ) for the correct parts of the frequencies. They looked to not be like Yagi where the reflector is larger and the preceding ( you have 3 so front looking over half the length, next two almost the same, but shorter ). You may also want to get some more wood and cut them in half, get some wire to connect the antenna to the middle directors in a cross pattern ( when held so the antenna is pointing right, bars up, top to bottom to top antenna segments and opposite for the pointing down antenna ). Good luck hunting down the Space Pirates.
I just finished an ELE 111 course as an elective in my welding program.
Had a great teacher and it was a lot of fun.
TH-cam recommends yet another great channel. Need to dust off my SDR and do some listening between applying for jobs while I’m outta work right now.
If you find any AM signals in those transponders, they are military ATC in the uplink bands (~300MHz) that are probably asigned without knowledge of the frequencies also being allocated for satellite uplinks. We do hear them from time to time.
You are right.
Some input frequencies coincide with sat input (specially non US mil users)
I have been watching sporadically for a couple days now, very entertaining, thanks for sharing that inquisitive spirit.
Oh my! The first pirate transmission was a short dialogue about a trucker asking if the other one is already loaded
Loaded with drug
I listening to many Brazilians and Russians, but there is also a small group of Italians, not all of them in Italy who have been making themselves heard for over 15 years, sometimes more, sometimes less, but Brazilians and Russians are on the increase, thanks also to Chinese portable and vehicular radios that have invaded the market, capable of transmitting on the rising frequency, pleasant contacts from Europe have been felt with the Russians in English, always kind and helpful, however there is no way with the Brazilians who insult immediately heavily for no reason.Ciao
as a brazilian i couldn't help but wheeze here, man, that just pictures us so well
Violent bunch the Brazilians ,still smashing heads in with rocks 😮
😂
I might have to give listening to those space pirates a go! I’m in the UK and the coverage into the US and Europe on your map looks pretty good.
The U.S. Govt legit SATcom stuff in the 250s these days are mostly secure data links. There's definitely still some secure & plain-voice USG Tacsat comms in the 260s -- some of it important stuff, But a lot of the USG Tacsat has migrated to MUOS CDMA with downlinks in the upper 300MHz area. Really annoying to hear the pirates for those of us that used to have to submit requests for UHf SATCOM transponder access back in the day & get in trouble if we used to much uplink power, etc.
WHy did it matter if you used a little too much power on uplink? I realize that you don't need a kw to access it, but enough juice to make a solid entry into the system. What kind of karens run that system anyway?
@@KlodFather As available power is shared across users, normally you uplink enough power so that the downlink power is enough to be received. If you uplink more power, the other downlinks will suffer, dependant on sat power budget. A major sat system I worked with some 40 years ago, had automatic individual and total uplink power adjustment. All users of the system had their uplinks controlled in this way.
I honestly had no clue what to expect when I clicked on this video. Pleasant surprise, this is actually really interesting!
Great stuff man
Nice Yagi antenna you whipped-up there! You can also cut up a tape measure to make flexible elements for the same.
Ha. The chopped up tape measure segments are also used for direction finders when fox hunting for transmitters. You can go rung through the undergrowth without the risk of being impaled by a ridgid element. Lighter also.
So cool. Reminded me of telephone Phreaks from the 80s and 90s
I think the lady says "My dog has no nose!" Then the guys is like, "How does he smell?!" The lady says "Terrible." Good channel, OM, 73

extremely underrated channel, I hope you don't run out of these ideas.
Former US Navy Radioman here. I went to school for this system in 1977 and used it at sea on a system called NAVMACS. It's amazing those transponders are still operational.

This is something I have been trying do with similar tech, quite a few Zombie Sats out there with no encryption on them some still with power at times (depending what and where). This content if fantastic, Love the back stories on the history of the tech the most. Thanks for the content :)
Wow, I can't imagine trying to hunt for these zombie sats. Hat's off to you for listening to them.
Your channel is so much of what I want do do, but haven't got the time or skills to do.
Best channel for my morning coffee.
A log periodic or yagi log periodic would give you the wider band. Your yagi is really on the low side gain wise. Down in the equator area, they will not need such high gain antennas. The voice you heard sounded like Portuguese which while closer to Spanish can sound a bit like Russian if you are not familiar with the two languages.
And I would have recognized Russian as I worked with a bunch of Russian engineers and started to learn the language from them. Its complex as hell but full of nuance and surprises. These clowns on that channel sound like a bunch of CB trash and should be eliminated. Shutting off the satelite for a year or two should clear the board. THe radios would fall out of use quickly when the system goes dark.
that is so cool! i am so happy i came across this channel, please never stop mate.
I'm definitely hearing some traffic on 255.550 today, even with a ground plane antenna that's not tuned for the band.
I heard almost nothing on that frequency all day when I was messing with this. I had read it was one of the more popular ones, but I guess I just picked a quiet day to listen!
I heard the female say ‘obrigado’, which is Portuguese for ‘thank you’.
Cool video and concept, cheers for sharing!

Hahahahaaaa your neighbor just freaking out watching you like, “ohh shit here he goes again” keeps watching as the equipment in your yard starts moving ”what the hell is that thing. Honey come look at this shit, our neighbors setting up some experiment.” 😂
Stumbled on your channel looking for new content, am genuinely interested and now subscribed.
NPR on 271 MHz is very common you will pick up FM local transmissions on 271 Mhz and even sometimes you will pickup shortwave transmissions, it is just a harmonic frequency. That is why you typically want to use an FM bandpass filter. IDEALLY you want to use a band pass filter that filters out everything except the band you are interested in, in this case 270mhz
This is wild. Dude do more of these.
I'm very familiar with Space Pirates (otherwise known as SPRT)
Honestly it's pretty easy handling their planetary bases and cargo ships, just need to pummel their pre-warfare weaponry with autocannons & Artillery, disable their AI, and then boom! You've got some new components and such.
(If you are curious, this is referencing Space Engineers. That is the joke)
I hate the damn space pirate scrapper ships. I’m just trying to test out the blocks from the latest update stop destroying my things.
Clang bless you, fellow engineer.
You are exceptionally inspiring. Thank you for this video
Most of those transmissions in portuguese that you've presented I assume they were made by truckers, they use some frequencies as a "team speak". And maybe... Sometimes Portuguese can be a little tricky and sound a bit Russian, phonetics are kinda similar
Hi there, the main "users" on the military Fleetcom VHF frequencies around 250 ... 260 MHz will be stations from Brazil. Here in the Netherlands they are easy to monitor, with a Discone antenna, or even a "vertical" for 2m//70cm.
Oh so this is the video where you're haunting pirates. I am an SWL from Italy, I use a superclassic omni Diamond X300 on a Yaesu FT-7800 vhf/uhf radio and I can normally pick up lots of Brazilians pirates, sometimes Russians but mostly people from Brazil. Yagi on VHF is good if you want to get a point-to-point connection, otherwise a good old simple J-pole will march quite nicely (if you only want to catch waves without considering the ROS, so not transmitting and say goodbye to the radio). I made one from various copper scraps and I can get ships and planes from 105 MHz to the 140 MHz. Though VHF are quite keen to pick up lot of noise, sometimes it's crystal clear, but I live 50 mts far from the Adriatic sea...
The idea of using a PTZ cam as a rotor is just awesome!
Cool, thanks for the info! I'm always learning more about antennas, I have an amateur license and have read some of the theory books, but it always makes more sense to me once I've actually tried it for real.
@@saveitforparts Ah, nice! I'm waiting for my license too. For now, '73 here, maybe one day we can try to catch on air, when I'll have some spare time to setup a DX (I sell marine engines... funny how we have common passions :D )

Yeah pretty sure I also came across this channel from the river boat series
@@saveitforparts my boat also, waist deep in snow!
Very cool nice work with stuff laying around. The show at 4:05 is a gem Flash Gordon filmed in Berlin.
I've not tested the metrics in any real comparative detail or to any standards other than the nanovna, though I'm still amazed how well my 450MHz yagi worked and works only using wooden rod with aluminum duct tape wrapping for the reflecting and directing elements. I invested in a 3D printer pen to make the mounts more adjustable for finer tuning. I never got around to making with the plastic knurled thumb screws or 3D printing, though did order and have most the parts I need if not all.
By the way, I thoroughly love the channel! I also picked up satellite signals at these frequencies shown in your video, but with my biconical antenna, it was too faint for the descriminator. Just heard extremely spotty voice.
Going to build a directional.
Sat comms were my favorite back in my marine days. We didn't have a geosyncronus satelite over head for the man portable kits I used. Instead I had to kinda guess where tf it was in the sky, aim the antenna at it, and see if it would transmit.
Kind of a pain, but I liked them bc the voice comms were always crystal clear.
But for reliability it was hard to beat the old HF radio with a field expedient antenna.
Cool! It would be fun to learn more about military radios and systems. I assume most of them are encrypted these days.
@@saveitforparts Encryption is a whole other thing. Stock they are unencrypted til you load crypto. We would use unenceypted chanells to talk to civilian run range control to let them know when we were going live, when we were done shooting, how many marines were on range, etc.
Since you are a radio guy, you prob already know, but if u don't I suggest looking into omnidirectional field expedient antennas. All you need is some copper wire cut to the right length for the frequency, a means of holding that copper wire off the ground. You can get comms with anyone using that same freq within 350 mile radius.
Field expedients were only workable with HF radios due to the length ratios required to cut the copper wire. (The length of the cut has a certain ratio to go with the freq, but I have long forgotten the tables for that) Not all info I'm giving u here is gonna be 100% spot on (I've been out for ten years) so I'm just goin off of memories.
Hope this will maybe give u an idea for a video you can do.
The language you picked up is Brazilian Portuguese, it is what we call PX, communications between truck drivers. This is soooooo nice! 😮
I think the female voice was saying "Help me Obi-Wan, you're my only hope...", but in Portuguese.
I had no idea this was even a thing and that so many people rely on these decades old satellites for communication! How nice of the US military!
They are speaking in Brazilian Portuguese, the woman tells him: "hide the cargo and stay alert. She will be monitoring this one and "the another one". I'll let you know if anything happens. The man just responds something that means "Ok, thank you"."
She is probably referring to the frequencies of the police, military, etc. and she will let he know if she hears anything.
In the second transmission, he calls someone and says he has just loaded the tractor
Lol man I could uae some friends like you! I have always been the "oddball maker"/"horder of electronics etc" one of my groups. The biggest problem with being interested in so many different things that require a good bit of experience and research to understand, is that you are lucky to meet anyone in person that is into even just one of those many things. It's ts a damn miracle to meet someone that is into more than one of them....at least where I have lived. Finding the time to do all the stuff you want to is another big problem with it😁
Anyway, fun times! Keep it up man!
ABSOLUTE best channel I've recently found!
7:42 it looks like portuguese
for me they're saying something like:
"sera que ele chegou na cidade carregado ou (dont undertand the rest)?"
translation is "did he arrive in the city loaded or (i cant undertand the rest)?"
probaly a truck driver from brazil (my country yay)
and the woman said:
"(dont undertand) so fica ligado ta? fica nessa rua ai"
"stay alert ok? stay in this road"
and the guy said: "positivo, positivo"
its something like "ok, ok" in english
and the girl said: "ok qualquer coisa so me chama aqui nelson, vou ficar ouvindo ela e a outra, ta?"
translation: "ok anything just call me here nelson, Ill be listening to her and the other one, ok?"
and the guy said: "beleza, joia"
translation: "ok, thankyou" (not literal translation, but he means something like this)
Hello Friend! Nice video! I speak native Portuguese, and I can sure tell you that all conversations are from Brazil. You are correct that most communications are from truck drivers and, sometimes, from farmers in the middle of nowhere. I can try to translate what they speak if you want.
Thanks! A few people have commented with translations. Maybe I should have recorded longer to find something more interesting!

"Help me Obi-Gabe....you're my only hope....."
This is incredible... A very strangely coincidental, but resourceful use of these sats lack of security. I need to get back into radios...
It'll be interesting if you get a better antenna and if or how much of a difference it'll make.
If I may suggest, @7:30, when you located a pirate station, it will help the intelligibilty if you narrow your IF bandwidth, to cover the signal only. The reason your audio was "fuzzy" was that your BW is too wide.
I've been able to receive these with an rtl-sdr and an omni directional scanner antenna on my roof here in central california, surprisingly strong signal. Usually Brazilians? using these repeaters from what I can tell
I am shocked that this was not clickbait. Really cool
In the twin cities there's MPR News at 91.1.The third harmonic of this would be on 273 MHz.... And there's KFAI on 90.3 MHz which would have it's third harmonic at 271 MHz but that's not MPR or NPR. Probably one of these signal is loud enough for you that the filtering after the mixer in the R820T tuner of the rtlsdr dongle can't knock it down below your noise floor at ~270 MHz. And then there's just some local clock error in freq that shifts it there.
Interesting, I wouldn't have expected a side harmonic to come in that strongly. I'll have to check if other FM stations do that too!
Interesting...as I am local. I know KQRS you can pick up darn near anywhere with the wattage they put out.
Just a question, if he was picking up the third harmonic of an FM station, wouldn't the signal stay somewhat constant if he changed the direction of the antenna? Wouldn't the harmonic be coming into the antenna/system from the side and not from the direction the yagi is pointed? I hope I asked that correctly. Thank you.
I was always wondering why i pick up FM radio signals with my analog 90's TV 😁(i use it for gaming).So it is a kind of unwanted FM transmission artifact.
At 7:28 I'm sure that is Brazilian Portuguese. Amazing channel!!!
It's crazy... I built a rabbit ear yagi almost the same way about 6 years ago. only thing I did different was use copper wire for the other elements. worked like a dream on 2 meters.

The majority of pirates are south american and portugese. As there is little or no enforcement of the law there by their PTT's. The last batch of crackdowns we heard about, those foung guilty were fined ~$50 and allowed to keep their equipment.
Where...?
@@jplacido9999 Brazil I think it was.
@@gonzo_the_great1675
Brazil, no doubt.
There were portuguese users too, but they were taken down by a joint operation by portuguese branch of NATO, portuguese National Guard, and Judiciary Police.
Brazil also made several operations against pirate users of Mil Sats.
There are still a few out there in the midle of nowhere....
Incredible! You are amazing!
The voices at 7:22 in are in Brazilian Portuguese. It's a dialogue, difficult to understand, but for those curious:
Male voice (7:22):
"Uai, será que ele chegou na cidade, (des)carregado? Ou derramou no meio da estrada aqui? Tem um negócio de derramar carga na [cortado]"
By the accent, I believe he is from the state of Minas Gerais.
Translation:
"Uai, did it arrive in the city, (un)loaded? Or did it spill in the middle of the road here? There's a thing about spilling on the [cut]"
Female voice (7:27):
"[?] Só fica ligado. Fica nessa [?] aí."
Translation:
"[?] Just stay tuned. Stay in that [?] there."
Male voice (7:32):
"Positivo, positivo"
Translation:
"Positive, positive"
Female voice (7:35)
"Qualquer coisa só te chamo aqui nessa. Vou ficar ouvindo essa e a outra, tá?"
Translation:
"Anything else, I'll just call you here. I'll listen to this one and the other one, okay?"
male voice:
"Beleza, Joyce"
Translation:
"Fine, Joyce"
Male voice (9:02)
"Como que tá aí oh Jefferson? Fala com nois. Acabou de embarcar o trator agora"
Translation:
"How are you there, Jefferson? Talk to us. Just loaded the tractor now"
Male voice (9:07)
"[?] Vou dar uma carga pra nois ouvir [?] 544" (não tenho certeza se entendi certo)
Translation:
"[?] I'm going to give us a load to hear [?] 544" (not sure if I understood correctly)
Thanks Wolverine 👍🏾👍🏾👍🏾
Came for the thumbnail, stayed for the sick radio wizardry.
Best not to fine tune antennas while they're resting on the floor. You might get away with it, but still... Best to have them at least a little bit further away from things.
Wow this is so cool! I'm an electrical engineering student and would love to do some project like this in my spare time as well!
Damn that was actually a really good pirate accent
around 9min mark it sounds like somebody in a diving bell or some deep sea application and it makes ur voice High pitch breathing in the mix under pressure 😅 interesting video to watch bro 👊
Most of the interlocutors are Brazilians, most of the things they speak are about the cargo they are managing, the word "carga" (cargo) is often. Why do I know this? Because I'm a Brazilian 🤭🤗 and I didn't know this exists, and I'm really impressed that there are so many people taking advantage of pirate transmissions. That's incredible! (I could translate most of the chats in Portuguese to you! Just ask me if you want that 😉)
Aqui no MT e no MS é muito comum, os fazendeiro e caminhoneiro tudo usa Rádio Amador.
@@DioneBatista legal! Eu não imaginava que os fazendeiros também usavam o rádio! Poderia me contar um pouco mais? Tipo, por que os fazendeiros usam rádio amador? Para se comunicar em caso de ataque de bandidos?

Did you not come across the car alarm ???
i don't recall the frequency around 268.7 there is a transponder with two active channels one is a car alarm type sound been on for months, the other is voice often.
i'm in the UK and i pick about twenty of more up each day using a simple ham antenna on the roof in to a cheap SDR..
I didn't find that one, maybe it's coming through a different satellite in the UK that I can't hear from the US.
@@saveitforparts not sure, i have a line of sight to the southern hemisphere so assume it's Satcom 7 i think it is..
i need to check which it is,
but very active to me, shame i can't understand a word they speak :)
For an Amish dude you know alot about tec !
In the 70's nobody used 250 MHz for anything, except all the military in the all world....
