ZR6TG has written up a good tutorial on how to use a rpi zero as a USB to Ethernet forwarder for QO-100 satellite. This enables you to get rid of your active USB extender cable and makes it possible to place the pluto and dish far away from the shack. Click below to check it out.
VIDEO. How to adjust your dish for QO-100 geostationary satellite:
Find Astra 28,2 degrees (strong signals in Northern Europe and Central Europe) with a low cost satfinder with sound / analog meter
This is one of the most eastern TV satellites that are very strong, so you can start east and move towards south until you find the first strong satellite on your satfinder (you should find Astra 28,2)
Now move a slight bit more to the south until you are out of the strong Ku band lobe of the Astra 28,2
You should point in the correct direction (elevation is the same in practice)
If you have a generic LNB the IF should be on 739,7 MHz. Your SDR should be able to tune to that QRG
