Could anyone living in northland check what type of signal levels they are getting on channel 70 discovery channel using the standard sky dish with monoblock. I'm getting break ups even in good weather with 80% signal level but down to around between 30 and 40% quality. I'm being told this is a good level but I'm not sure.
I had the same thing happen to me last year, and it turned out to be the Sharp Dual-throat LNB was failing. Sky have replaced many thousands of these around the country due to LO drift. At first, some channels are affected but not others. Then it gets slowly worse until nothing works. The amount of drift is temperature dependent so with these colder nights we are getting now, it may get worse.
If your LNB is a light grey colour with a "Sharp" label, and is Dual-throat (elliptical dome on the front), I'd be pretty much certain it is the cause of your problem.
I think you may have hit the nail on the head so to say, the sky enginner did mention this but when I gave the signal reading tonight he said they where perfect, The thing is I'm not stupid and I have filmed the channel breaking up and shown the ber readings in the same video.
On another not my moto box is losing ept, I have posted about this in another thread, but I am being told its is a sky fault and they know about it. Load of crap if its a known problem I'd like another box to try.
