Hallo George,
I use Gentoo-Linux. The Distribution has only gnuradio-3.8. 5.
So I can not use gr-dvbs2rx. A great pity. It is a problem with the
varied versions.

Hallo,
ich bin neu hier und grüße alle OM . Mein Name ist Henry DH5RUM.
Ich besitze eine Mini GPS Referenz Clock von Leo Bodnar.
Letztes Wochenende wollt ich in deine umgebauten
Octagon Quad LNB die Referen 25 MHZ einspeisen.
Ergebnis : Der LNB funktionierte nicht. Kabel alle Okay.
Unmodifizierter Oktagon Quad LNB funtioniert auf allen
4 Anschlüssen.
Ich habe das Sinal des GPSDO mal geprüft.
Sieht komisch aus. Ist das so in Ordnung?
Falls ich was hier im Forum falsch gemacht habe, ruhig Bescheid sagen!
Danke für Eure Hilfe.
