Did you test it ?

i have to make some adapters to use an old LNB : i set the sf8008 as universal lnb (tone for band select) .
i juste change the OL values .
i want to keep 14/18V as polar change .
i detect 22k to change power supply for old lnb .
i keep 14/18 to change polarotor value .



to make some test with PLL lnb on my prime focus i made some aluminium pieces , i dont make change on original lnb just
put a aluminium ring stuck in the horn.

Are there people who use a mechanical polarotor?
in KU band?
Which LNB: OL=9.75-10.75 band select 14/18V or OL 9.75-10.6 band select 22khz?

On my EGIS installation I am going to put a mechanical polarotor and a 9.75/10.75 LNB and I am going to add a small interface to control this LNB with 22Khz.
Does this interest anyone?

Not so long time ago I've got this LNB for PFA with mechanical polarizer. It changes H to Y by applying some DC voltage to the motor.

Nowadays it only makes sense to have/use OL 9.75-10.6 I think. But since you are making "something unique & special", ideal would be a choice.

I designed this small assembly so that an old LNB (9.75/10.75 -14/18V) + mechanical polarotor can be recognized by the sf8008 as a universal LNB with OL 9.75/10.75 instead of 9.75/10.6.
It works very well, you have to adjust the two polar values at each satellite position.


here is the schematic

if someone can gives me advice about L2 L3 C7 values .
i dont have active splitter or opened devices to see similar values .

when sf8008 send 22k (high band) , 22k is detect in posi and send 18V to L3 .
when there is no 22k signal posi send 13V to L3.
sf8008 send also 14/18v ,posi use this to manage polarotor (no change to L3).

The larger dish in the garden has a Co-Rotor which uses the same circuitry for both C and Ku band.

I have been working on the EGIS engine for several months, I adapted my JPC-POSI (positioner) to this engine.
AAL41 and FEMI have this model.
I added an autofocus function based on the AGC signal, it's less precise than the SNR quality signal but it works very well.
I also added a function which allows you to approach a position always from the EAST (by going beyond the position to then return), this allows you to make up for the mechanical play.
I also did the same thing for the elevation.
To be able to test in the best conditions, I mounted an old generation LNB (9.75/10.75 band selection by 14/18v) on a mechanical polarizer.
Using a small adapter board, the SF8008 is configured in user-defined LNB mode: the 22k is diverted to activate the band change and the 14/18V changes the H/V polarity.
I would like to know if any forum readers would be interested in my EGIS positioner version or in this adapter intended for polarotor chaparral type installations.
