according to an article in the latest cqDL, we've ordered two LNBs from reichelt. With the cases open, we could see that they don't match the layout from the article, at all :-/
When powering it up, I cannot measure anything like 5 or 3.3 V, anywhere. Therefore we can see that the power supply is directly connected to the bug saying T101702 03 SD813 (see 2), which makes me think this device is directly powered with something from 12-18 V?! It has also has a connection to both ends of the xtal (3).
How can we modify this to a TCXO version? How do we get the correct voltage?
