    Lucio, I logged in as administrator. In the settings the soundcard was only found in the output field. Without soundcard found in the input I can't play the sound from a WAV/MMV-file.

    hi Thomas, forgive me but I still don't understand what kind of radio you are using and how it is connected to the PC. Based on this answer there is a different solution.

    Yours appears to be a Windows / microphone access permissions problem. On which device do you send the audio signal from the radio? Set this device as the default recording device. Then make sure that the various programs are authorized to access this device. In Italian I could show you the exact path but in your language I don't know ... Then set the execution of the programs that interest you as administrator. Unfortunately, Windows is originally rather armored and touches to eliminate many software barriers that for our purposes are just annoyances.

    Hi Gio, you can safely use a TV-SAT splitter. Be careful, you need a splitter that passes the supply voltage for the LNB to only one output port. The other port must be electrically isolated to avoid possible trouble.

    Insertion loss problems do not exist in this case. In fact, the more you attenuate the conversion signal, the better the SDR works.


    Ciao Gio, puoi usare tranquillamente uno splitter per TV-SAT. Fai attenzione, ti serve uno splitter cha faccia passare la tensione di alimentazione per l'LNB su di una sola porta di uscita. L'altra porta deve essere elettricamente isolata per evitare possibil guai.

    Problemi di perdita di inserzione non esistono in questo caso. Anzi, più attenui il segnale in conversione e meglio funziona l'SDR.

    Andreas, look at minute one and ten seconds if that's what you're looking for.

    The company Es'HailSat announces that tomorrow, April 1, 2021, the satellite Es'hail-2 will be moved to the orbital position at 30 ° East. This maneuver is necessary due to the entry of the satellite into the constellation of fish. The satellite will remain in this new orbital position for 24 hours and will subsequently be moved back to its assigned position. Customers and satellite users will have to move the antennas to the new location but only for 24 hours. Starting from April 2nd, everything will be as before.

    Disclaimer: I cannot and will not give any technical details of the QO100 transponder due to NDA. But I think it is obvious that any space-qualified transponder oscillator will have very good stability values so for the sake of simplicity we assume it is non-significant compared to the numbers above.

    Ok, it seems fair to me. However some features of the "Melco" Satellite Platform DS2000, the same as Es'Hail-2, are known.

    Here the characteristics of the Beacon (commercial). The same that we find on V. 10.706 GHz.

    Maybe we can start from here?


    P.S.
    not everyone is able to receive this Beacon as it transmits on MENA Beam



    Hi Phil,

    If in your area the TV-SAT dishes are positioned on Astra 28.2 °, all you have to do is position yours in the same direction. Just a little bit to the right. If you have a small Satfinder, like this one in the picture, (6-10Euro) it will be much easier to find TV satellites. Once you are on the right elevation for small horizontal movements it will not be difficult to get to Es'Hail-2 / QO-100


    Without irony and with the utmost respect for everyone ...

    but you really don't sleep at night for a 70-100 Hz deviation in a 2.4 / 10 GHz amateur system?

    Do you think interplanetary probes are more accurate than your system? yet they work, they go to other planets and they don't even have GPS. How will they sleep at night?

    ISS crew will work out a plan of repair and restoration work

    Cosmonauts of Roskosmos, currently working on board the International Space Station, and specialists from the TsNIIMash Mission Control Center (part of the Roscosmos State Corporation) will work on a further plan to eliminate leaks in the Zvezda module on the ISS on March 8, 2021. This was reported on Monday in the press service of the SP Korolev Rocket and Space Corporation Energia. Korolev (part of the Roscosmos State Corporation).

    “Today, as part of the work to eliminate leaks in the Zvezda module, the crew of the International Space Station, under the guidance of specialists from the ISS Russian Segment Flight Control Operations Group, will work out in detail a further plan for repair and restoration work,” the press service noted.

    The commander of the 64th long-term expedition, Roscosmos cosmonaut Sergei Ryzhikov and ISS-64 flight engineer, Roscosmos cosmonaut Sergei Kud-Sverchkov, in consultation with the Mission Control Center near Moscow, will step by step study the radiogram of further actions and prepare the necessary equipment for processing the module surface, applying sealant and patches.

    I had booked out of technical/technological curiosity and today I received the offer from Starlink.

    For those who live in the city, served by optical fiber, Starlink is definitely out of the market.
