The FSS LNB (121°W) is linear and will work on 97W. Not sure about the V8 but a LOF of 10750/13850 should handle the bandstacked LNB
I tried on 97W... It does work to some degree. But the limited size of the dish and the mediocre performance of those stacked LNBs caused some problems. I think it was a combination of interference from 95W or 99W, and limited signal strength. I am however using one successfully for 123W for KBS. I set the LO to 10750 (or 10742 if I can, to compensate for the LO drift). The V transponders scan in with the expected frequencies, and the H Tps display some higher frequencies in the 13 GHz range due to the stacking. Most receivers don't have a proper setting for the bandstacked LO, if you enter it as a dual-band LNB, you'll get even crazier numbers as it will try to switch with 22k tone
so all in all, the stacking is a nice feature, allowing to get both polarities without swithing, on a single cable, at the cost of not-so-intuitive displayed frequencies, and mediocre performances.
this page has a pretty clear explanation of the stacked LNB:
also, it's fairly easy to replace the feed/LNB assembly with a regular linear LNBF with a mounting bracket. There's even a hole in the LNB arm that is perfectly located. I got better results that way than with the original stacked LNB.

When I was using those stacked lnb's, I noticed they had HORRIBLE noise figures. Like 1.0 and above.
I had that type of lnb when I started in FTA. Iceberg told me to scan vertical only since its dual stacked. Rather use a pll lnb instead for better signal.
Years ago I had access to a huge pile of SuperDishes and played with a bunch of those FSS linear LNBS.

I found an old DTV triple LNB that had removeable feed horns and grafted those onto the FSS LNBs.
My SuperDish Mod to multi-LNB FTA Dish
Dead 121 SuperDishes are everywhere in the NorthWest. So I have plenty to work with. I modded the FSS LNB by putting a feedhorn from a DTV triple on it. I made three this way. I then fashioned a bracket to hold my new LNBFs and put them back on the SuperDish. The first attempt was 87W, 97W, and...
