    Downside, youll need over 10Watt FM to get a desent S9 R5 signal...

    In stead of the 4 watt needed for a similar USB signal...

    Hi Benno,

    This is already the reason.. FM is the most ineffective method on satellites and we just don't want to promote this among other technical reasons. We also have had abuse in the past using strong FM on both NB and WB.. There have been a period of experiments using FM as a back channel, but it was not feasible for the above reasons and that's why we banned FM in general on QO-100.

    Der eBay-Link taucht weiter oben mehrfach auf und funktioniert... wo ist das Problem?

    Wenn jemand es hier aber überstrapaziert (wie geschehen), dann müssen wir korrigierend eingreifen.

    Wir verdienen hiermit auch kein Geld und stellen das Forum kostenlos zur Verfügung.

    In general, we ask not to post any commercial or trade offers in this forum.

    There is nothing wrong with individual offers for purely personal and non-commercial reasons, but here too there should be no price discussions and a discreet approach.

    Ideal zum neuen DownConverter V3d passt natürlich ein von AMSAT-DL fertig umgebauter LNB, d.h. modifiziert für eine Referenzclock direkt gespeist aus dem Down-Converter und dort durch einen hochstabilen OCXO oder TCXO+GPS erzeugt.

    Weitere Details sind der Beschreibung des DownConverter V3d auf unser Webseite zu entnehmen.

    Wichtig: die externe Referenz liegt nur am "WB" Eingang des Konverters an und muss dann entsprechend auch mit dem oben gekennzeichneten Anschluß des LNB verbunden werden!

    a small reminder for given reasons:

    Remote operation of an amateur radio station via QO-100 is only permitted if the station belongs to the operator himself and is operated at his own location. He must always have full control over the station and in particular be able to switch it off immediately if, for example, interference occurs. Special cases of unmanned and automatically operating stations require both permission from the operator of the space station, in this case represented by AMSAT-DL, and special permission from the regulatory authority responsible in the respective country. The international and national legal regulations must always be complied with by the operator. The above agreement is in accordance with AMSAT-DL, AMSAT-UK, QARS and Es'hailSat.
