agc fluctuating signal too strong

[Bk456]

Ok my agc in jumping from 0 to 100. But only on some channels...I have been advised this means the signal is too strong...

But on bbc1 which has probably the strongest signal of all I am getting a solid 74% signal...sky christmas is also solid. I haven't went through the rest...but most sports and movies are jumping....

Im getting a bit of glitching i feel is down to this...

I know a satellite attenutor would lower the signal but Im not sure if thats even the case....I just live in a small bungalow, quite an old dish with quad lnb. neighbours don't have these problems.....

You really should be getting 100% on BBC m8,if the ones that are jumping are lower then your highest of 75% then thats your problem,either dish is misaligned,LNB is goosed or cable is knackered

I upgraded my lnb to a quad from a single. But the old one pulled out very easy and the new one pushed in nice and tight...set for skew 3 as I'm in northern ireland...

im not sure what else could have went wrong...

And were you getting better signal with old LNB?

Are you using any diplexers/wall plates?

 

[Bk456]

No diplexers or wall plates, just cable straight through the wall...

Yea I'm going to put my single lnb back on but if it's better then what shall i do. I need a bigger lnb for my dual tuner box

If signal is better, then the quad LNB is faulty,or maybe you have not configured your dual tuner correctly
