    yes, this is Brazilian portuguese. A little hard to understand, but one of the guys is saying that he's running out of battery and needs to clean his "board" (not sure what he means) during the weekend. Basically, it sounds like they are setting up their radio systems.

  • @Suzuki_Akira
    @Suzuki_Akira 4 роки тому +152

    They are not all “pirates” intentionally as the input “uplink”’ to these few particular satcom channels happen too be in the legal bands in Brazil for commercial / business band / public bands similar to fm cb..... also in a few of the channels they are using the frequencies illegally BUT they are not talking through the satellite intentionally, just simplex on the ground from truck to truck as example, the normal daily traffic your hearing is mostly trucking operations with no clue they are on the satellite and it is not directly on the satellite input / uplink frequency either which why the quality of what your hearing is poor and off center carrier from the output your listening too. This started almost immediately when these sats were first put in service due to poor frequency management on the uplink side plus very high receiver sensitivity and with the main beam being in the lower Southern Hemisphere- Brazil region centered and these particular uplink / input channels are wideband linear which also playing into the issue. This has been a “conspiracy topic” with tons of wrong / misinformation since it started... The configuration of the satellites uplink / input linear transponders will not allow for reconfigurations that could be done to block the close frequency, they are using in Brazil, without effecting the other operational needs on these sats so it is just a fact a few channels pick up these users unintentionally. Yes there was a few cases of true malicious / illegal stations but what is heard daily on the few channels is not this case.
    It is a Portuguese dialect with strong slang & abbreviations used heavily plus with the signal being off frequency on the uplinks input and the modulation index is higher then intended for the sat it makes it harder to understand too.

    • @jplacido9999
      @jplacido9999 4 роки тому +17

      Most is intentional. Been there for decades now. Some guys in Brazil and Portugal even specialized in modified ham radios and commercial units (Motorola, etc.).
      The first excuse from the "promoters" of the selling of the units was that they were using abandoned satellites. It was true at first. They would chose "past life" sat's that were "overshoooting" expected operacional life. Frequencies were carefully choosen to avoid troubles with the military.
      But as units were being sold to everyone, less care was being taken, and soon started lots of abuse.
      Mainly used by truckers, it became a sat CB.
      Abuse of language, truckers tallking from Germany to their wives in Portugal, truckers in Amazonia (Brazil) in long chats, and illegal activities communications in South America became regular.
      In Portugal, in the early stages of "brazilian copycats" I've warned those guys that there should be no normal use of UHF satcom for chats like CB. That was not a good idea.
      But people pushed it (brazilians were doing it for years allmost without any trouble).
      After a while, chaos and abuse was standard:
      Long chats, interference with italian navy NATO coms, and the likes.
      There were even guys using digital voice to avoid interception by other pirate users😀.
      Things went so bad that a joint investigation by the Judiciary Police (high prestige Police), ANACOM (the portuguese FCC), GNR (kind of National Guard but with daily police action) and NATO military resulted in a border between Spain and Portugal welcome to truckers with prision arrests envolved.
      Same in Brazil:
      Next generation military direction finding (US military guys don't joke arround) led to precise pinpointing of pirate use, even in the Amazonia jungle.
      Activity went down a lot after those operations.
      The bad sound in this video is a result of low quality SDR (high quality SDR based receivers cost thousands) and a improvised antena (you should use a direccional antenna pointed at the satellite).
      Some satellite transponders would let you get in touch with military tact teams in deep South America and Far East at the same time !!!!
      Hope my information was usefull

      yes they know what they are doing, there are people specialized in sales of equipment to operate these satellites here in Brazil, most of them are truck drivers who use the system just because there are regions that do not have any type of cell phone signal, they end up buying radios and installing and using it clandestinely, the guy who sells the equipment sells a kit that consists of a conventional vhf radio (136 to 174) and a converter for (250 to 320) and an antenna that is called a shower head.

    @redneckhippiefreak Рік тому +5

    While looking at the transmission without sound, I noticed how much of the band lit up..Plus, it looked like Morse code. That made me think the speech could be cover for the actual encrypted info that is piggybacked with each packet. It is an old CIA technique to do so. It was explained to me as "Kind of like playing a song in the back ground of a recorded conversation, You can hear it but you don't notice it much". The trick is, knowing the correct frequencies to cancel out and which ones to enhance so you can hear the actual transmission clearly and catching the signal as it too modulates within the frequency being used. . Think of it like Noise canceling headphones. An entire conversation could be going on in the background while two guys seemingly talk about dead batteries and cleaning a solar panel. Mundane yet jam packed with info. Doubtful but entertaining to think about.

    One of this pirates used to send SSTV (slow scan television, no motion, only pictures) signals on one of the UFO sats consisting of old black and white pictures of some kids, a family, again kids and so on. Now, he (or she) moved to the new (and first) hamradio Oscar 100 part of a Quatar geostationary satellite. Nobody knows why he sends the photos, to whom, maybe he is ill, but he is not a full. He knows how to build the setup for Oscar 100 sat, aswell as he knew how to acces UFO sat until now. The transmission goes all day long, no identification, no voice, no explanation, nothing but theese old b/w pictures.

I also had to put a noise reduction filter but my reception was a bit better than that from your video, I bet if I tune the antena to 250 MHz I would receive it much clearer.

      A word of warning though, you by law need to be licensed to use any of these things and licensing is free in most countries just need to pass a test. You however can freely listen to transmissions without a license just can not transmit without a license.

    I live in Germany (South Hesse) and have received them without problems with a similar setup described in this video. A Diamond X-300N antenna (12m above ground), 20m coax (ecoflex 10) and a 10€ generic RTL-SDR (that thing with the blue plastic case).
    It the cheapest setup I used so far, the most important part is of course the antenna which must be able to see the horizon and a good cable. I have also used other SDRs like an Airspy and an USRP B210, but the RTL-SDR works too. The only difference is, that the noise floor of the RTL-SDR is a bit high and you won't be able to see the noise of unused transponders on the satellite.
    A friend tried the same, but he used an old TV antenna pointed into a random direction. He also had limited success, the carrier was barely visible in the waterfall diagram and the fft plot (with a lot of averaging to get the noise down).
    (But after having received them and knowing that it works, it becomes boring real fast. I haven't tried it for over 2 years, but when it was new, it was quite exciting)

    The antenna on the fltsat satellites looks circularly polarized. How did you manage to receive the signal with a crossed dipole? And how long was each pole in the crossed dipole antenna?

    • @vk2ig
      @vk2ig 4 роки тому +3

      Crossed dipole is easily made to receive circularly polarised signals by introducing the appropriate 90° phase shift between the signals from each dipole before combining them and feeding them into the receiver.
      Alternatively, just use a single dipole to receive a circularly polarised signal, and tolerate the 3 dB loss of signal strength.

      LordHog - If you’re new, definitely stick with sdrsharp, for now. Just properly installing the drivers, can be a bit of a challenge. However, there are some great step-by-step tutorials, on www.nooelec.com
      Gnu radio runs under Linux, which, if you’re not familiar with using it, may not be your best choice. Also, when using gnu radio, you have to ‘build’ each radio, in the software’s interface, which has a very steep learning curve, unless you REALLY understand how radios work. (I’ve been an EE for 31 years, and sometimes find it challenging.) The real advantage of gnu radio, is that it allows you to transmit, if you’re using a HackRF One.

      The reception with these satellites is great. My dad used to talk way back, like 2003, 04. There were much more HAM operators than there's today, they all used codenames, and it wasn't just Brazil in the past, my dad used to chat with plp in Portugal too, in especial with 2 guys which their codenames were "Asterix" and "Obelix". We later found out they were two helicopter brush fire pilots. Everyone stopped chatting using these sats when the feds busted some guys that sold upconverters. My dad never bought and always made his own converters, very easy to do. Nowadays it is very sad to see that the sats are being used for illegal things, but back in the day it was very fun and plp were very nice.
      As far as we Brazilians are concerned, we don't give a fuck that these satellites were designed with linear transponders and no authentication, it's the US Navy problem, and they should deactivate the fleet somehow, but they don't seem very concerned because this is going on for more than 20 years and the only arrests were made only because some guys were building and selling the converters
