Amateur Satellite Communications Using QO100, Part 1.

[@ronleblanc9832]

very interesting used to install 10 foot satalites in the past then the smaller ones for a bit those were fun times

[@aaronakiyama]

That's awesome! We need to get a geostationary sat like that here above the US

[@RadioPrepper]

Space X...

[@aaronakiyama]

@@RadioPrepper that's cheating 🤣🤣

[@RadioPrepper]

Elon Musk might give amateurs a good price on a launch..

[@The_Last_Post]

Great result Gil 👍 cool experiment getting satcoms going!

[@Robbie12GS]

I always enjoy your experiments!!!

[@0Fluxor0]

Good luck with the next steps, QO100 is very cool. Only wish we had something that supported this hemisphere like the QO100. Cheers

[@justinelliott3529]

😂 I started on the French version by mistake. Great video!

[@AdamosDad]

The essence of the hobby and art of radio. Thank you, Gil, I'm looking forward to part 2. ✋73's🎙KD9OAM🎧📻📡

[@M7XCB]

Very interesting video and thank you for doing it in English.

[@adrianmatusik]

now you need to work on the transmitting part. I have such a satellite set based on Icom 705 and a 60cm antenna. You can take a look at my QRZ under the callsign SQ5AM. Regards.

[@RadioPrepper]

I'll check it out, thanks.

Très bon vidéo Gil, merci et 73 de va2sib

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.

[@RadioPrepper]

I have friends who used 2.5W.

[@KevinReeve]

Now we need one to cover the North and South America continents so we can play.

[@oherrala]

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.

[@RadioPrepper]

Definitely possible!

[@daveschwarz5279]

Would be useful with WinLink, but not very packable. Wonder how minimal a station could be?

[@RadioPrepper]

That's probably the minimum dish size.

[@2j4ez]

is that a universal LNB?

[@RadioPrepper]

Yes.

[@Andy2e0ree]

Hi brother great video 73

[@510109]

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]

Thanks Nigel. I just found a Mac version somewhere.. To transmit I will use SDR Angel, I think...

[@510109]

@@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

[@RadioPrepper]

Well done!

[@survivalcomms]

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 !

[@RadioPrepper]

Less than a minute..

[@humaxf1]

Interesting. Do you have a link for the SDR dongle please? Thanks

[@djamelait8905]

Bonsoir stp une vidéo en français merci

[@RadioPrepper]

Elle arrive dans 5 mins!

[@JohnDerrick-cc4yd]

What LNB are u using and what voltage please

[@RadioPrepper]

A generic model, 13V.

[@skyking6989]

Not gonna work as i live in North America. Awesome nonetheless. Licensed ham myself. Maybe someday ill get on the birds. 73

[@F8FFP]

Quel est le logiciel utilisé pour la réception ?

[@RadioPrepper]

GQRX

[@F8FFP]

Merci

[@NamasenITN]

Did they sound French speaking OMs?

[@RadioPrepper]

French and Italian.

[@ammocraft]

My wife also tells me I’m special…but it isn’t meant as a compliment! 🤣

[@RadioPrepper]

LOL!

[@noimnotarobotcanubeleiveit7024]

The best thing about using qo100 is americans cant listen in😂

[@RadioPrepper]

Americans are not all in America 😉

[@lorenkuhn3806]

He gives off such strong narcissist vibes. wouldn't want to have to deal with this dude irl...

[@RadioPrepper]

I've been called a few things, but that's a first. What could I have possibly said that might make you think that?

[@Bob814u]

Always great content. 72! de KE5ES
