    Congratulations Rolf for the first QSO with A71A..

    You are a real satellite DXer for long time and you certainly deserve it !!

    We are looking forward to hearing you from rare DX countries with your mobile satellite station..


    I think you heard my whistelinng noise and you just hit us at the right time when A71A (Operator Sabaan A71BP) took the microphone..


    6 Years ago I was first time in Qatar at the Ham Radio Festival and Qatar National Day.. Now we are here again and so happy that our dream comes true..


    We had a great openening ceremony with the Prime Minister of Qatar watching the live video from HE Abdullah bin Hamad Al Attiyah, A71AU, on the big screen in the control room from Es'hailSat.


    We could see that all the parties involved, including government and Es'hailSat were very delighted with this success.


    Indeed we all can be very greatfull to Qatar and the QARS for giving us this fantastic opportunity and for supporting worlwide friendship, humanity and education through Qatar OSCAR 100.

    Man sollte aber schon darauf achten, was man übernimmt. Mir scheint dieser Termin unrealistisch, da ja noch die AMSAT-DL-Tests ausstehen.

    Lieber Thomas,

    selbstverständlich wurde die Bekanntgabe zwischen Drew Glasbrenner und AMSAT-DL abgesprochen... und es ist ja noch nicht Mitte Februar.. :-)

    Gruß Peter

    Lieber Hans-Jochen,


    habe erfahren, dass die Empfangsmischer Kit's heute in Bochum angekommen sind.

    Die Sendemischer sollen ebenfalls in Kürze ankommen.


    Ein paar Vorbereitungen müssen noch getroffen werden, aber ich denke der Versand wird in ein paar Tagen beginnen..


    Die Kollegen machen das ehrenamtlich, mit tatkräftiger Unterstützung durch Mitarbeiter von der Sternwarte...


    Es wird also gerade noch "just-in--time" ;-)


    vielen Dank für die Geduld...

    Sehr geehrte Damen und Herren


    Projektleiter von Satelliten-/Nanosatelliten-Projekten möchten oft Amateurfunkfrequenzen, Frequenzen die für nichtkommerzielle Bildungs- und Kommunikationszwecke gedacht sind.


    Die Gemeinschaft der Funkamateure bietet ihnen somit ein enormes Potenzial zur Beobachtung ihrer Aktivitäten, ja teils sind diese Satelliten vollkommen von den Empfangsberichten der Funkamateure abhängig.


    Die Betreiber fragen oft, welche Art von Amateurfunknutzlast an Bord eines Cubesats für die Funkamateure interessant wären oder welche Dienste sie mit ihren Kommunikationssystemen anbieten könnten.

    Die Antwort kann einfach sein: ein Transponder, aber diese Designer möchten auch Neuheit und Innovation mitbringen.


    Um mehr sachlichen Input zu liefern, hat AMSAT-F beschlossen eine Online-Umfrage zu starten, um herauszufinden, welche Satellitenaktivität sie nutzen oder nutzen möchten und was Sie von den Satellitenentwicklern erwarten. Aber auch, wie sich die Funkamateure einbringen können und dazu beitragen können.


    Die Ergebnisse der Umfrage wird AMSAT-France auf seinem 2.ten Treffen "Rencontre spatiale Radioamateur " am 9. und 10. März 2019 in Nanterre (Frankreich) präsentieren.


    Zögern Sie nicht, geben Sie Ihre Meinung ab, indem Sie den Fragebogen über diesen Link erreichen:


    https://framaforms.org/amsat-francophone-survey-1548716436

    Die Umfrage ist auf Englisch, wird aber auf einem französischen Server gehostet. Nur wenige Hinweise könnten auf Französisch sein.

    On 15 November 2018 Es'hail-2/P4A was launched with a SpaceX Falcon 9 launch vehicle from Cape Canaveral Air Force Station Space Launch Complex 40 in Florida. Es'hail-2/P4A was jointly developed by QARS (Qatar Amateur Radio Society) and Es'hailSat (The Qatar Satellite Company), under the technical leadership of AMSAT-DL, and is the first geostationary amateur radio payload. The satellite reached its final position at 25.9°E and the narrowband and broadband transponders were successfully tested on 23 December 2018 and 16-17 January 2019. The transponders are expected to open for general use in February 2019.

    At the request of AMSAT Deutschland e.V., QARS and Es'hailSat, AMSAT hereby designates Es'hail-2/P4A as Qatar-OSCAR 100 (QO-100). May the 100th OSCAR satellite be the lead star for future amateur radio satellites and payloads in geostationary orbit and beyond.

    Hi Thomas and all,


    this had nothing to do with "old" modules. The Launch Opportunity from US Government with their payload simply disappeared.... which was a big disappointment for all involved. Some people believe there might be another one coming up.. So far, P3-E is still in Bochum, as it was reported in AMSAT-DL Journal and otherwise.


    Regarding SpaceX launch opportunities.. I had first direct contacts with Elon Musk in 2008, followed by a SpaceX representative visiting AMSAT-DL in Marburg a few month later to discuss possibilities..

    At that time we hoped to make a launch contract for P5-A, payed by the german government, which would also include the launch of P3-E. The P5-A project was cancelled by DLR some time later.


    Unfortunately there were and there are no free launches (anymore), but we still kept contact over the years.


    One day before the P4-A launch I had a chance for a longer meeting with a well known person from SpaceX and we talked about test flights as well. SpaceX had customers on earlier test flights, but they changed the policy to not launch any "customer" payload anymore on such test flights. Perhaps because they fear too much bad feelings and bad press when such a test flights fails..


    Technology, Knowledge, Tools (for design, simulation, etc.) and quality have so much improved over the last decades, that they just need only a single test flight before going into regular business with commercial customers on it... Remember how many rockets failed in the past.. some rocket programs where only known for failed launches..


    That's also the reason why on the first Falcon Heavy flight they just put Elon's Tesla, apart from the media attention.. Though I told it would have been nice to have a real "radio" on it on amateur radio bands... ;-) But that was simply not their priority..

    The next Falcon Heavy will already launch Arabsat...


    Definitely, when there is an opportunity we will try to grab it...

    For sure we discussed some potential ideas, which always have to benefit both sides... but as usual, not much can be said here and time will tell..

    Lieber Joachim,


    gerne können wir einen Beitrag im AMSAT-DL Journal abdrucken, wenn ein Zusammenhang mit Satelliten und möglichst auch Amateurfunk besteht..

    Wegen den Details kannst Du Dich gerne mit unserem Redakteur, Thorsten Schmidt, DO1DAA in Verbindung setzen.

    E-Mail: redaktion@darc.de


    Besten Dank im Vorraus und viele Grüße

    Peter



    Of course, feel free to reinvent the wheel ; -)

    I think nobody is reinventing here anything. Some people may just prefer to buy a ready made weatherproof solution for little money..

    Hi Maurizio,


    thanks for the good wishes.. we are also very excited indeed.

    Our equipment for the ground control station arrived in Qatar and we hope to travel soon to Qatar for installation and the opening ceremony.. But we might still have to wait a few more weeks..


    With P3-E unfortunately no progress. The hoped launch opportunity in US did not materialize..

    In dieser Stereo-MP3-Datei ist die Originalaufnahme der Aussendung von APOLLO 11 aus Bochum auf dem rechten Kanal und die NASA Net 1 Aufnahme (aufgenommen in Honeysuckle, aber von Goldstone kommend) ist auf dem linken Kanal.

    Die Sternwarte Bochum hat mit dem 20-Meter-Spiegel direkt vom Mond empfangen, deswegen hört man auf dem rechten Kanal die Bodenstation und deren Roger-Beep auch nicht.. :thumbup:

    These were really good times for ham radio and international friendship & collaboration.. We need more of this...


    Leonid Labutin UA3CR was a great man and I'm still in good contact with his son Eugene (RZ3AAO).. He visited me many times in my home and whenever I'm visiting Moscow we meet...


    When reading some of the messages from Vladimir's archive, I remember that I once received a "top secret" encoder & modulator for the command uplink in an attempt to override the Informator-1 control when the satellite felt silent.. All the hams in Hannover got mad on this strange signal.. hahaha


    I could not resist to open and look inside of the "black box". I was totally impressed by the engineering work. I also remember that there were many miniature tubes. And it looked very different from what we knew in the West. Really amazing..


    Looking back, the Radio-M1 with RUDAK II and INFORMATOR-1 with the planned Koskon constellation were somehow ahead of time...

    Thanks Vladimir!

    I added also your above links to the AO-21/RS-14 page.

    I have seen information which I even have forgotten.. Seems I was the first one to hear our RUDAK beacon to be turned on unexpectedly.. :)
