Hallo und guten Abend habe nun ein neues Notebook mit Geforce 1650 das laut Nvidia auch H265 Encoding kann aber im OBS wird das mit H265 nicht angezeigt. Gibt es einen Trick ?

QRH of the DK0SB-Beacons? I hear the that frequency of the uplink beacons is jumping a few Hertz -- at least I sincerely hope its the uplink and not the SAT!

We are currently investigating the Beacon jumping.. might be a problem in Bochum with the central 10 MHz GPS/Rubidium reference..

Due to instability of our HP Z3801 (GPS-locked) 10 MHz reference we switched over to a back-up R&S Rubidium reference in Bochum (DK0SB). It's still warming-up, so some offset is possible.

The reference frequency is too low and thus the beacons are transmitting about 230Hz too low ... it is planned to correct this in the next days ...

TNX, guys! I am really happy that the bug is in the Bochum ground station and not some 35.000 km abover ground ...

after some warming up the Rubidium frequency seems to be pretty much on frequency now, at least it's stable and not jumping anymore; giving is some time for repair or new equipment...

Maintenance work at our QO100 AMSAT ground station in Bochum from 09:00 to 18:00 UTC on Saturday, 23 January: LEILA and beacons are temporarily switched off or unstable. LEILA could strike unintentionally

6W-PA für ADALM Pluto verzögert sich noch um 1-2 Wochen, da die Verstärkung noch weiter verbessert wurde und ein paar passive Bauteile getauscht werden müssen..
