Correct, Change all three to 10750 Or as I said earlier, use Circular.

We can look at the file where these settings are managed in the link below.
[Only registered and activated users can see links. ]

Lines 466-469 show how Circular lnb is set in enigma2 for OpenATV:
elif currLnb.lof.value == "circular_lnb":
sec.setLNBLOFL(10750000)
sec.setLNBLOFH(10750000)
sec.setLNBThreshold(10750000)
So all three to 10750 or use Circular. Either one should do the same thing unless OpenATV has changed their blindscan coding.

Other lnb settings will work, and it does not matter what you use as long as you are satisfied with the results.
