Thanks for online streaming!

Like it! Thanks!

Unless you like to smd surgery, either buy a new one or as you said use it for TX only.

Hi George, use a free dropbox account and provide the link.

Well, what would you like to do? I use the bullseye for stability and easiness to mount a helical TX antenna on it. Simple setup and works.

It all depends on which software you are running. I use an Apple I7 mac pro because I like the MacOS for day-to-day work and installed Bootcamp with a WIN10 partition for SDR Console and the Adalm Pluto for QO-100 portable operation while in Europe. Works beautiful!

If you look up the launch vehicle, it is limited to put a 6000 kg payload into a low 200 km orbit or 4000 kg into a sun-synchronous orbit.

The first launch took place in December 2022 but failed to reach orbit. I assume the proposed launch will include a number of payloads.

Sounds great! Please let us know what works for you.

One of the best tools to use for a portable station with a pluto and a laptop is SDR console! It will only run on Win. I have used it successfully for 3 months in Italy and it was a blast (see my QRZ page). So get a laptop with a processor and enough memory that runs Win, SDR console with low latency. For example an I7 processor (newer generation) and 16GB Ram. Hope this helps,

I believe that this experience shows the potential weakness of not having redundant control/operation stations. I hope that AMSAT-DL will take this opportunity and look at backup and redundancy. QO-100 operation is too important to have only Bochum available. This is just common business practice and highly recommended.

Thanks, yes makes sense. The new mini V2 uses a new FPGA (Lattice ECP5). I assume it will take a little bit of time for code, firmware etc., optimization by the community.

Currently testing the new Lime SDR mini v2 on QO-100 receive only. It is a bit noisy and appears less sensitive then the Pluto since the unit is not shielded and the settings for the unit are not optimized. Will try TX soon. Anyone else is using it? Feedback?

Great idea! I hope AMSAT-DL can work something out.

Have been QRV for a few days now. Lot's of contacts already. Basic station setup is either Adalm Pluto in SG Labs amplifier and 60cm foldable dish with Bamatech LNB/Patch, or FT-818 in Amsat QO-100 Transverter and SG labs amplifier into 20 element Yagi. Amazed how great the Yagi works and so much more portable (fits in suitcase).

Merry Christmas and to each its own. Already tuned away...

Not sure why you make this such a massive "science' project! I have Pluto, a laptop with SDR console, headphones, my preamp and SG labs final amp, a small power supply, and a POTY with a modified LNB. All on a 40+cm travel dish and will be online in 3 weeks from Italy. It really is not that difficult.

New scheduled launch on Sept. 30th at 12:01 AM - 2:00 AM PDT, with a backup on Oct. 1st with the same launch window.

Looks like it is scrubbed again (weather). The next possible launch attempts are the 19th or 20th.

There are commercial 10GHz antennas, but I am aware of nothing that has been combined with 2.4GHz. At this point, I would recommend waiting until we know the exact frequencies available with the IC-905. There are enough brilliant people out there that will be excited and ready to make a combination antenna for use with QO-100 once we know more about the IC-905. Until then, save your money (a lot) for the IC-905 Remember, the amateur radio frequencies available are 10.0 to 10.5GHz and the NB transponder is at 10489.5 to 1049.0. Let's just hope Icom will make the full amateur radio band available. Should be common sense.

Hallo Peer,

Freue mich für dich das du jetzt eine neue Station für Euro 1000 hast die dir gefällt. Meine Kosten waren um die Euro 550 und mir gefällt meine Station und die Ästhetik ist überhaupt nicht zu vergleichen

Zusätzlich habe ich AMSAT-DL unterstützt und das war eben auch wichtig und die Erfahrungen und Spass den ich im Zusammenbau hatte sind unverkäuflich! Nein, du hast mir keine Illusionen genommen. Mach dir keine Sorgen... .

Alles Gute und hoffentlich hört man sich auf dem QO100 in Januar 2023 wenn ich wieder in Europa bin! Bin dann mal gespannt ob deine Station Euro 450 besser ist...
