      Hi Pawel,

      If you mean three points(dots) of light, they are not a defect, but rather fires (burning wood or dry grass).

        Hi Oleg,
        Related to your comment regarding the fire spots..
        During daylight passes of Meteor, is it possible to observe ..lets say..large satellites equipped with solar panels, orbiting the Earth at lower altitudes than 800 km ??

        1. booinform@gmail.com Автор записи


          100 percent not say, but it seems to me that this is possible only if the lower satellite sunbeams shine toward the top of the satellite.

    If the signal is to high would the SDR-RTL «distort» the received audio? I put up a new antenna for 137 MHz and works well. And I had a nice strong signal through out a 49E pass. But LrtpRx Constellation Diagram turns into a square at about 7 mins into a 12 min pass and nothing is decoded beyond that, then at about 10 mins into the pass the diagram becomes 4 dots again but nothing further was decoded. Being it was 22:00 local on Saturday night and the sat was above Australia I’d have a guess and say that no one was commanding the satellite at the time!

    I’ll do some more testing by switching over to a QFH when the sat is over 35º to see if that makes a difference. But makes unattended recordings a bit hard 🙁

    Any idea when they will turn on all sensors? I only received one picture from the visual sensor.

      My source of information about the commands supplied on board Meteor now on sick leave and I can not provide accurate information on what was going on board at this time.
      All six channels simultaneously transfer is not possible. Any combination of three of the six. And it is also possible to program the change combinations several times per orbit for the week ahead. Now ROSHYDROMET (the main customer of the satellite) must issue a decision which combinations will be installed during normal operation.

    Think I can now answer my own question….

    The AGC in the SDR-RTL that (I guess) is controlled by SDR# is distorting the audio when the signals are to high. I just had a 55ºE pass and I switched antennas from the X-Yagi to QFH at around 40º which did ok. But I switched back to the X-Yagi to early and lost 4 mins of data from to high a signal.

    So if you been having trouble decoding very high satellite passes but do well on the lower ones. Then you might have to much antenna gain looking up. Maybe a collinear would be a better choice? I’ll build one in the future and see how it preforms.

    Or a better SDR would solve the problem. But hey! It’s only $10!!

      Undoubtedly they are the fires. Volcanoes in this part of Russia is not available. Maybe some of these fires on the Ukrainian territory and some in Russian one. The Ukraine is also no volcanoes.

    Hi all,
    I’ve recently finished my QFH and while trying to recieve Meteor I’m having problem with LRPT_RX not detecting any signal whatsoever, same with decoder. Does anybody have similar problems? The satellite was 70deg. elev. so that is not the case. BTW. I recieved NOAA APT satellites and they were perfectly fine cause I»ve got nice clear picture and they were much lower.

    Attaching screenshot from LRPT_RX and Decoder


    Thanks in advance and greetings from Poland.

      1. Wiktor

        Thanks, Sergey.
        I’ve already probably solved my problem cause I’ve noticed that my center frequecy was not set to 137.1 MHz. After setting it to 137.1 I’m getting signal, but whole image is black, probably because the satellite is on the dark side at the time I recieved it. Will try in a couple of days and see if its OK though. But thanks for help.

        Greetings from Poland

      i have had the same problem in the beginning,untill i started to use an amplifier,
      this one was for portable scnanners, but you can also try any tv-amplifier,
      the signal has to be ampliefied a little so it comes above the desired level to get a carier-lock in the decoder,
      believe me after that you will have your first picture ! (you did resample your recording in audacity to 130000 ? thats very important to !)
      good luck ,Peter from Holland.

    1. peter

      exelent pictures you have!
      did you use a tracking antenna with x-y rotor ?
      did you use an amplifier ? if yes, wat type of amplifier ?

      like to hear from you,
      greetings from Holland.
