The point is that V8 Finder2 has the output freq. 950-2150MHz. That's it. LNB wideband has output freq. 290-2350MHz.
Even if you set LNB freq. 10450MHz you are not able to set TP freq. below frequencies that are translated below 950MHz and over 2150MHz,
e.g.:
LNB 10450MHz, TP freq 10760 => 10760 - 10450 = 310MHz BELOW 950MHz (Finder2 does not support below 950MHz)
LNB 10450MHz, TP freq 11760 => 11760 - 10450 = 1310MHz OK (it is between 950 and 2150)
LNB 10450MHz, TP freq 12760 => 12760 - 10450 = 2310MHz TOO HIGH (Finder2 does not support above 2150MHz)
Hopefully, it is clear.
I don't know what a chip is in the V8 Finder2. Maybe output freq. 950-2150MHz is limited by firmware only.
I have seen a video on Y.tube with the title 'Configuring the GT Media V8 Gold Satellite Finder for Terrestrial Digital Amateur TV Reception', user G8YTZ.
There is an older V8 Finder Meter that has output the same as V8 Finde2 950-2150MHz but the finder supports freqs below 950MHz.
GTMedia has V8 FInder Pro also. This one supports terrestrial freqs that cover lower freqs for Wideband LNB 290-950MHz. Unfortunately, Finder Pro does not support LNB 10410MHz. In this case, I am sure it is a firmware limitation, not the hardware.
