I got a couple questions with it and specific LNB's, for example I set the meter for 91 and connect my cable to 91 lnb, all I get is the first bar go to like 150-200 + and does not show a quality, even though on the inside on my receiver, I am getting 80+ quality and signal,

if I set to my 110 LNB and i re-connect my cable to 110 LNB, I see good signal qualiy on the meter

my 91 and 110 LNB are the same type, its a dual circular lnb.

I also got a twin circular dual lnb (the one that catch's 118 and 119 in one). how do I see the signal on my birdog for that?
