The specs of the LMB:
RF: 12.1 - 12.6 Ghz
LO: 11.0 GHz
IF: 1100-1600Mhz
From the frewview website the freq etc..
TVNZ Frequency: 12483 MHz
Kordia/TV3 Frequency 12456MHz
Symbol Rate: 22500 hsymb/s
Polarity: Horizontal receive
FEC: 3/4
So the input frequency is fine. I can't find any trademe auctions that list the IF frequency (input to the settop box I think). The dish itself is only 40cm but I think its worth a try. New LMB? Thoughts?
