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...

"Nothing is eaten as hot as it is cooked"

Let's wait and see the real price. it will be just fine One can say a lot about Icom, but they are not stupid.

Euro 1000, das tut weh! Hoffe AMSA-DL wird bald wieder Komponenten fuer eine Station bereitstellen.

Sounds good! Was just wondering. Thanks!

Why do people always think that every single radio useful for satellites has to be full duplex?

Where is this misconception coming from?

Yes, it is helpful to have everything in one radio but not necessary at all. There is nothing wrong using two radios (RX, TX, RX/TX) for satellite ops. So many folks do this every day!

Any new updates on these patches? Availability? Any shirts available with the logo?

Thanks Peter,

unfortunately, the webinterface requires the TX data from the downconverter to be send to the RX pin of the PIC for both, the upconverter data and the downconverter data to be shown. I just used the RX pin of the PIC directly (which was a pain in the $%#$@ to solder) and got it going. Would be nice to have that pin accessible in the next version. Thanks again, Stefan

Hi Thomas,

while IARU frequency coordination for amateur radio satellites is highly desirable and beneficial it is not mandatory.

Trying to build the web-interface for the AMSAT-DL up and down converter (AMSAT-DL Journal 3-2020). I need to find the contact (pin) to route the TX data of the downconverter to the RX port of the upconverter to have both serial data available for the web interface. According to the article, the revision 4.3 of the upconverter is supposed to have a separate pin for RX (it has one for TX). However, it looks like there is none, unless someone can point to it. It is not available at the 6pin connector where the TX pin is located. The only option appears to be connecting it directly to pin 15 of the PIC (18F2520) or the tiny resistor in front of it. Appreciate any thoughts.....

Thanks, Stefan VE4SW

Super! Vielen Dank,
