    A PDF of the journal exists anyway at the DARC editor.

    Ask our friends at AMSAT-UK, I'm sure they would help us.

    Well - Yes, we also receive the Journal electronically as PDF before printing.. that's not the problem.

    As I said above, our current membership database and our internet servers are not connected.. also due to privacy.

    Doing this manually would require additional work for which we have no resources at the moment.

    We already planned to change our membership to an Online system earlier this year, but we are not really satisfied with that software so far.. Once we have a good solution, it should have a private area for members where we can also put signed PDF files..

    Hi Thomas,

    we had that discussion in the past, but the majority of the membership voted for continuing a printed paper version of the AMSAT-DL Journal.

    eMembership in fact requires more resources (people/software) to handle the whole process, i.e. from authentication that you are a real member (connection to our database and to the the serve) and to allow to download a private copy etc..

    At the moment we have no solution with our existing membership database and server for an easy solution without too much manual work load..

    If you have an solution or if someone wants to volunteer, let us know..

    Hi Mike and Karen,

    sure you can use a second transceiver or separate monitoring receiver, but than it makes the IC-705 no more special compared to others.. at least not at as satellite transceiver. Indeed, it's still a nice portable device and if you own two of them still no too heavy.

    Maybe we'll have to wait a little longer, surely ICOM didn't want to have a direct competitor to its own IC-9700. But a smaller/lighter portable version of the IC-9700 would be very interesting for many QO-100 users, but also especially for friends of the LEO satellites., no need for 50/100W Output on satellites..

    73s Peter

    Hi Mike,

    I know and trust that you are an experienced person and you know what you are doing.. no problem..

    I was not only thinking about QO-100, but also about portable QO-100 and LEO satellite operation..

    Conclusion: The ICOM IC-705 is definitely NOT READY for Satellites...

    So in this case the IC-705 is nothing special or new... it's a step back, in particular if you don't want to carry another computer with an SDR...

    The other point is about simplex operation:

    We have discussed this here and elsewhere many times and the ignorance to rules given by the QO-100 Transponder Bandplan and Guidelines is sometimes disappointing. In "portable" operation it does not help at all, if you don't have internet... and to completely depend on an internet connection to a WebSDR, is not what I think is good practice. It's OK when you are just starting to get up on QO-100, but it should not become a standard and it should not be promoted as a good solution..

    On AO-40 the time delay was twice as much compared to QO-100 because of 60.000km apogee :-)

    Sorry, I have taken the liberty of modifying the title a little bit ;-)

    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!

    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
    on September 26th 2020

    Unfortunately, the AMSAT-DL Symposium planned for September 26th and 27th, 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 (

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

    from :

    ... 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 Thanks to @HAMSATNL and @ppapadeas for discoveries

    [Blocked Image:]

    ... 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.

    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.

    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..

    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..
