Hi

Is this fair?

Can anyone explain it?

What does it mean: "Quartz Cristal Control" in this LNB?

What is on the underside of the pcb?

SP3OSJ Artur as I know all BEST typs are DRO. "Quartz Cristal Control" is not in there.

The two screws are probably for tuning a ceramic resonator ... No quartz

This is ceramic generator DRO, no quartz.

For use in my constructions there is only a teflon lens.

DRO vs PLL:

Hi Artur. All written on the cover not more than COMMERCIAL GIMMICK. In the article you are present is about all and about nothing. In any case, you can use this device, but remove DRO disk and inject external LO frequency 3,25 GHz, where LNB working on 3rd harmonics of external LO. Is not new, first time making in 1992. Todays radio amateur was testing this issue, it's correct.
