An 'it works for me' and a suggestion.

- 'it works for me':

I have a Universal LNB, I'm in the UK, my VDR settings are (setup.conf),

LnbFrequHi = 10600
LnbFrequLo = 9750
LnbSLOF = 11700

- A Suggestion:

From,

"
Receivers typically accept L band signals in a range starting at 950 MHz.   If 
you want to receive satellite signals starting at 10.7 GHz then you need a LNB 
LO of 9.75 GHz.  Maybe Astro are starting some services in the band 10.7 - 
10.95 GHz ? 
 
For satellite TV, 'universal' LNBs with switchable LO frequencies of 9.75 and 
10.6 GHz seem to be common. 
 
For Ku band reception, LO frequencies of 10, 10.75 and 11.3 GHz are also 
available. 
"

No idea, just guessing, try rearranging your values in the same sort order a my 
'it works for me' section,

High LNB frequency (MHz):  11700
Low LNB frequency (MHz):   10750
SLOF (MHz):                12500

Don't know if this will fry your silicon.
