Hello Sat Friends !
After modification of lots of Single- and Twin-LNBs for external LO input and the use of them I found it uncomfortable to have only one IF output.
So I decided to modify a Diavolo Quad LNB for external LO, which gives me 3 simultaneous IF outputs now.
I use one for the NB-Transponder converter, one for the WB-Transponder converter, and one for a SDR-Stick.
I wrote a complete modificationreport in my Forum for you.

Hope you find it interesting.
