very cool for portable satellite operation, but is it full-duplex capable, i.e. does it have a satellite mode??

No surprise, the 2.4 GHz uplink lies in the same band where WiFi is operating. Your transmitter simply blocks your WiFi on 2.4 GHz.

Try to switch WiFi to 5.6 GHz and switch 2.4 GHz Off.. most Smartphones nowadays support 5 GHz WLAN.

You can also go into the configuration of your Router or Access point and switch "Auto Channel" Off, than manually select a fixed WLAN channel.

Example Fritz!Box (sorry in German):

This might help too... let us know if it helped....

Just moments ago Thomas DG5NGI uploaded a new Firmware to our DATV equipment via internet remote access to the Es'hailSat control center and downloaded Logfiles for further analysis.

Hopefully the DATV beacon will now be more stable, until we replace the hardware next year.

Sorry Dear Lucio, I don't want to cause more headache on you, keep calm.

I want to emphasis that I would say exactly the same if it would have been a German company violating the rules, no doubt..

Yes, you are right.. every national country have the power to grant a license, even if it's not according to CEPT or ITU rules. This does not make the world better though. We all know that there exists Banana Republics with basically no rules, just money or nuts. Several European companies, Universities, even from Germany have licensed satellites in those countries. However, it is our right to protect our amateur radio bands, complain and caught attention to ITU and our national regulator. We did that in Germany too! Yes, there is a "gray zone", but we already see improvements.. just being quite and accepting that can not be the answer...

We might also get support from a completely different side. Other companies may now rub their eyes and feel economically disadvantaged because they have to pay for commercial frequencies and have other disadvantages.

I can tell you that we have been approached by European startup companies asking if we could help them to license a satellite in Germany, which was already denied by their national administration after IARU denied the coordination due to incompatibility with the amateur satelliteservice. After consulting IARU and DARC we also could not support this proposal. Finally they found an amateur satellite group of another country which gave them an alibi...

However, an Amateur Radio Satellite is not justified or qualified by being built by amateurs, universities or organizations like AMSAT. A satellite working in the Amateur Satellite Service is clearly defined by it's purpose and usage, not who build and payed for it!! Even a commercial company is allowed to build and operate amateur radio satellites, as long as they fulfill the definition given by ITU as partly described above.. Otherwise QO-100 would not exist!

Quote from I0LYL

Universities often work closely with commercial companies. You will remember that even Pacsats were sold in some form of Kit.

Very good example actually !!

All those PACSAT's where completely transparent and open. All modulation formats and protocols were published in public. And in fact I can't think about any other company which did it better job than SSTL in UK to include and not exclude radio amateurs!! They even involved amateurs to participate, apart from downloading camera images, they gave us a wonderful Store&Forward packet radio communication tool for world wide communication and they provide the software for free! They actively involved radio amateurs in communication and education. I personally had a lot of fun with them, analyzing the telemetry, downloading camera images etc.. In addition, later UoSAT's, like KITSAT and POSAT were using amateur and commercial frequencies completely separated from each other to conform with the rules, because they were getting more and more into the commercial business. Nowadays they do not include amateur radio anymore because of commercial business on frequencies outside of the amateur bands..

For sure, these satellites were "demonstrators" with full participation of radio amateurs to exploit the feasibility for later commercial missions (on commercial frequencies).. Nothing against that, it's actually the purpose of amateur radio.. education and development of new technologies, which does not exclude later industrialization.

I can't see anything of that with ION-SVC (ION mk01), built by D-Orbit. Nothing is published, nothing to learn from it, the satellite even does not identify himself.. everything in the dark.. this has nothing to do with "educational" purposed and "studies", "experimental licenses" etc.. After all, we are now dealing with legal studies, so we are learning... Hey!! - so it's in fact an educational satellite

But as I said.. I don't want to cause more headache and ill stop here..

Enjoy amateur radio and the satellites, have a nice weekend..

Hi Lucio,

ION-SVC (ION mk01), built by D-Orbit, is an commercial satellite (platform) that carries 12 commercial CubeSat's from Planet to be deliver to orbit by them. They inappropriately use the the amateur satellite service spectrum as their only UHF T&TC on 437.515 MHz (Uplink and Downlink) in a completely for-profit mission.. I can't see how this even fits into your table above... Normally ITU has special international frequency spectrum assigned for such satellite services, outside of the amateur satellite service.. the ITU and CEPT rules are very clear on this...

So sad that DK1YQ is no more among us, he was our expert on these ITU matters and I remember discussing a similar case with him.. that's how I came to the above conclusion...

73s Peter

It can not be in the interest of ITU member states in general, if a single member country violates the rules and allows commercial misuse of frequencies devoted to the non-commercial amateur satellite service, while other member country's companies have to pay licenses and have to go through all the processes to apply for commercial frequencies.

With the first OSCAR satellite launched more than 50 years ago, Volunteers as from the OSCAR group, AMSAT organizations worldwide, LibreSpace and other open source amateur satellite organizations fight for open, democratic and not-for profit use of our assigned space spectrum with affordable launches, competed by commercial misuse of our amateur satellite service spectrum by others. Somehow the community could feel betrayed.. we paved the way.

AMSAT-DL Online Symposium am 26. September 2020

Das für den 26. und 27. September 2020 geplante AMSAT-DL Symposium kann leider in diesem Jahr nicht in der gewohnten Art stattfinden.

Da uns die Gesundheit aller sehr am Herzen liegt und der gesetzliche Rahmen zurzeit keine andere Möglichkeit zu lässt, haben wir uns entschlossen eine Versammlung vor Ort in Bochum in diesem Jahr nicht durchzuführen. Wir bedauern dies sehr, aber die Räumlichkeiten lassen nur eine Belegung mit weniger als 20 Personen zu.

Ein “geselliges” Zusammentreffen mit gemeinsamem Abendessen ist leider auch nicht möglich, ebenso wenig wie ein Flohmarkt und andere Aktivitäten, wie das während der HAM Radio Messe in Friedrichshafen 2019 erstmals durchgeführte QO-100 Usermeeting.

Stattdessen werden wir das Symposium als “Online”-Tagung in DATV über den Breitbandtransponder von QO-100 und im Internet auf dem YouTube-Kanal der AMSAT-DL (https://www.youtube.com/user/amsatdl) ausstrahlen.

Zeitplan für den Samstag 26.9.2020 (alle Zeiten in MESZ=UTC+2):

Aufgrund des internationalen Publikums werden die meisten Vorträge in Englisch gehalten.

Der jeweils aktuelle Zeitplan ist auf der AMSAT-DL Homepage unter https://amsat-dl.org zu finden.

Wir möchten Sie alle, auch im Namen des Vorstands der AMSAT-DL, herzlich zu der diesjährigen AMSAT-DL Online-Tagung und dem virtuellen QO-100 Usermeeting einladen.

AMSAT-DL Online Symposium
on September 26th 2020

Unfortunately, the AMSAT-DL Symposium planned for September 26^th and 27^th, 2020 cannot take place this year in the usual manner.

Since the health of everyone is very close to our hearts and the legal framework currently leaves no other option, we have decided not to hold a meeting on site in Bochum this year. We regret this very much, but the premises only allow an occupancy of less than 20 persons.

A "social" meeting with dinner is unfortunately not possible either, nor is a flea market and other activities, such as the QO-100 User Meeting, which happened for the first time during the HAM Radio Fair in Friedrichshafen in 2019.

Instead, we will broadcast the symposium as an "online" meeting in DATV via the broadband transponder of QO-100 and on the Internet on the YouTube channel of AMSAT-DL (https://www.youtube.com/user/amsatdl).

Schedule for September 26th 2020 (all times in CEST=UTC+2):

Due to the international audience, most of the lectures will be held in English.

The current schedule can be found on the AMSAT-DL homepage at https://amsat-dl.org.

We would like to invite you all, also on behalf of the AMSAT-DL board, to this year's AMSAT-DL online conference and the virtual QO-100 user meeting.

Clear violation of ITU rules and use of amateur radio frequencies for commercial purposes.. wow...

from https://twitter.com/ea4gpz/status/1304161121167978496 :

... the unknown satellite at 437.515 MHz is ION SVC Lucas by D-Orbit, which is registered as an Amateur satellite but doesn't have anything to do with Amateur radio nor has sent @IARU coordination. API/A at https://itu.int/ITU-R/space/asreceived/Publication/DisplayPublication/17440 Thanks to @HAMSATNL and @ppapadeas for discoveries

... this satellite was denied frequency coordination by IARU in 2018. Interestingly, the description of the satellite and supporting organization are quite different from what the satellite has ended up being. http://amsatuk.me.uk/iaru/declined.

Hallo Roland und alle,

Gute Nachrichten:

Ja, die neue 6W-PA für PLUTO wird in Produktion gehen!

Details folgen, sobald verfügbar...

PA0DLO reports on Twitter:

The unknown satellite that transmits telemetry on 437.515 MHz appears to be ION-SVC Lucas (ION mk01), built by D-Orbit SpA. This is a platform that carries 12 Planet Labs Cubesats, to be released at a later date.

Jean Marc 3B8DU reports:

MIR-SAT: In November 2020 it will be sent to JAXA who will fly it to the ISS and it will be launch by the KIBO’s robotic arm in 1st Quarter 2021. The satellite will carry a camera and also a Radio Amateur digipeater (bent tube) at 9.6k bauds AX.25 GMSK.Callsign: 3B8MIR IARU.

Quote from I0LYL

It is as if, somehow, the scheduled reset every 24 hours is not working properly.

Yes, we had a similar behavior 2 days ago.. it was OK after the automatic reboot, but this morning it seems to have happened again..

If Corona allows, we are planing a replacement (new) HW for next year.

Manual reset is not an option at this time.

Another Firmware update was already planned for these days, hopefully it will cure the problems..

73 Peter

Yes, but on the other hand an US company was fined by US FCC a few years ago with a lot of money.. they are back on this flight too, but using non-amateur frequencies this time.. as it should be.

Just ignoring is not OK.. there are ITU regulations and we have to enforce them by reporting intruders and make them public.. most of them want to make a business and bad publicity might not be good.. sometimes they need to be educated one or the other way..

Quote from DH2VA

what about asking our friends from ISISspace? I think they had plenty of customers on board..

Done - not sure if they might report back officially due to NDA

But normally every launch provider has to ensure that licenses are legally issued to give launch authorization and ITU is informed about used frequencies. Perhaps someone will find out what's (if et all) in the database..

Excellent analysis from Daniel Estévez, EA4GPZ, who just wrote on Twitter:

"I confirm that the unidentified satellite from #VV16 which is transmitting on 437.515 MHz (probably illegally) uses 1k2 FSK with a @GomSpaceGroup AX100 transceiver in ASM+Golay mode.

This is from a packet received earlier by Mike DK3WN. Nothing seems useful to ID the satellite."

Quote from DB2OS

And there seems to be another unknown satellite infringing ITU rules for the "amateur satellite service"...

Nico PA0DLO made Doppler measurements, which show that the unidentified satellite is object 46273 (2020-061B). Frequency: 437.515 MHz.

In this case SatNOGS will be very helpful to us to identify and document those illegal transmissions in the amateur satellite service:

https://network.satnogs.org/ob…ver=&station=&start=&end=

PE0SAT and JA0CAW have already analyzed the recordings using the 1KUNS-PF decoder from Mike DK3WN, but no identifier was found. But could be another format... Several people are currently working on it..

there seems to be also 9k6 FSK AX.25/APRS transmissions on the 437.800 MHz Downlink..

Quote from HB9SKA

I hope SatNOGS will ignore this CubeSat, I do it.

I agree...

see https://community.libre.space/…launch-2020-09-03/6360/24

"This satellite is not coordinated, but we need to keep track of it for identification reasons"

I'm not sure what this means... who cares?

And there seems to be another unknown satellite infringing ITU rules for the "amateur satellite service"...
