    Hello OK9SGC and welcome to the board!


    Technically possible, but as far as I know it's not legal to retransmit any transmission from Eumetcast.


    Even if for individuals (non-commercial use) the license is free, you still need the personalized USB key and they exactly want to know who is receiving it? We can try to contact Eumetsat to check what's possible..

    Hi Ed,


    I think the downstream bandwidth will just be too widewith the available minimum Symbolrate of 2.5 Msps and Datarate 2.5 Mbps for the WB transponder...

    Hi Conrad,


    the 75 Ohm cable from the LNB to your down converter or SDR is not critical as typical LNB's have around 60dB of gain. With only 10m of cable, absolutely no problem.


    The only reason to use better quality cable would be if you need a better shielding, for example when you are close to a mobile network operating in the 800-900 MHz IF of the LNB. Perhaps look for cables with good shielding designed for outdoor.


    There are a lot of good SAT-Shops, but Amazon should also do fine. Reichelt.de is also a good resource.

    Hat diese absichtliche (?) Miss-Nutzung irgendwelche Konsequenzen für den Betreiber?

    Moin Rainer,


    ich fürchte nicht, offensichtlich ist man da mit ja durchgekommen.. und wo kein Kläger... IARU?


    Spätestens zum Jahresende werden wir es wissen, dann sind mehre Nachfolger geplant... vielleicht hat sich hinter den Kulissen etwas getan...

    Hello OM,


    The CAMSAT XW-4 (CAS-10) satellite was launched into the Chinese Space Station on November 12, 2022 aboard China's Tianzhou-5 cargo spacecraft, and was launched by the Long March-7 Y6 launch vehicle from the Wenchang Launch Center in Hainan, China. It is currently planned that the XW-4 (CAS-10) satellite will be separated from the Chinese space station and enter operational orbit at 01:30 UTC on December 18, 2022.



    Attached is the CAMSAT XW-4 (CAS-10) Amateur Radio Satellite User's Manual V1.0, for your reference.

    New DXCC Entity VK9QO will be on the Air between 25-31, October 2022.

    Operation schedule and QSL information is as follows:


    Location 1: 25 -27 Oct 2022

    Cocos (Keeling) Island (VK9C) Local Time=UTC + 6.5hr

    12°05’S 96°53’E GL: NH87JT (Az: 274.1 deg Elv: 10.1 deg)


    Location 2: 28 – 31 Oct 2022

    Christmas Island (VK9X) Local Time=UTC + 7.0hr

    10°29’S 105°39’E GL: OH29UN (Az: 271.9 deg Elv: 1.7 deg)



    The operator, Mikio JA3GEP, will try to QRV mainly late afternoon and early morning UTC. He operates split. He will listen 5 kHz or more higher frequencies only.


    LoTW and eQSL, as well as paper-QSL, will be handled.

    Please visit JAMSAT-HP https://www.jamsat.or.jp/?p=2001 for detailed QSL Information.


    This activity is supported by ICOM Inc. and JAMSAT(Japan AMSAT).


    QSO with VK9QO is valid for “JAMSAT 50th Anniversary Award 5 points bonus”.

    See https://www.jamsat.or.jp/?p=1854


    Thank you for your interest.
