Amateur Satellite Communications Using QO100, Part 1.

Ғылым және технология

There is at this time only one geostationary satellite open to amateur use, QO100, owned by Qatar. In this video I explore reception of HAM signals using a parabolic antenna and RTL SDR revceiver. Would SAT COMMS be of any use for prepping? Let's try it...

    That's cool you got it up and running . How much time did it take to optimize your dish manually ? I know the VSAT stuff I mess with is automated and it takes several minutes to incrementally optimize . Thanks for sharing !

    Great video! The frequency drift you are observing might be coming from the LNB and it's built in oscillator. The oscillator is not as stable as needed for narrow band ham stuff. Some SDR software can correct the drift by locking into QO-100's beacon.

    Congratulations on another excellent presentation Gil. If inclined, any chance of including topic of how you set-up GQRX on your Mac in a follow-up video? e.g. Did you need to run any additional applications or an emulator? Have you tried any other SDR applications? Keep up the good work and hope your Christmas has been everything you wished for and that the New Year exceeds your expectations! 73 from KG43eu

    @@RadioPrepper All noted Gil and I also located a 'Mac ready' build. Worked without any fiddling EXCEPT no audio... After exploring, I found setting relating to 'modulation' and once a mode set, audio was present. Plan to complete my portable QO-100 station soon(ish) and perhaps will be able to make contact with you via the satellite? Good luck with whatever you try using on the Tx side. Looking forward to your next production (especially if it includes 'scenic' footage of wherever you record) for sure. Stay safe. 73

    I wonder how much power one needs to transmit for the uplink? When I lived in the states I have seen some serious operators working microwave communications. Some of their amplifiers were upwards of 10 watts at around 10.525 GHz. This was for point to point land comms. For a successful uplink I would think around five watts would do good making the hop to the bird.
