I am trying to get SBS, Nine, Go and Gem and am having no joy whatsoever!
I have an old sky dish, a newish zenus quad output 10750 ku band lnb and a vesta 7300 dvb-s2 receiver.
I am receiving the freeview channels with 98% signal and 98% quality with the above, but nothing with the frequencies and transponder settings from Lyngsat for the aussie channels.
I am I doing anything wrong, or are any of the parts I have not right/working..?
When you recieve good signal strength and quality from one transponder but poor or non existant from another on the same satellite it is likely that the skew of the LNB is your problem. A quote from another geekzoner on another forum thread:
Your dish has to be perfectly aligned with skew to grab what signal it can, and as its polarity and transponder differ from the rotation of the NZ freeview ones, can be tricky to obtain both at the same time with 100% hitrate.
It is difficult but possible however, I use an old sky dish installed by sky technicians and have not touched it. I am able to recieve Freeview with near %100 strength and quality and around %60 on the australian channels.

What are we talking here in terms of getting the skew right...? I've tried carefully and slowly turning the lnb around to see if the quality bar goes up (currently 0%) with no luck.
We almost need to merge these threads into a big aussie TV motherload :)
Yep, Skew angle of 1deg can be the difference between on and off. Even twisting it with the head still tight can make a difference.
I too have a sky installed dual head, it gets the church channels on C1 with 22k switch enabled (as you expect.. but all of those are on skip, its for the V8s :) ) and all the sky/freeview off D1.
The upshot is I also get fairly good signal on SBS. However due to their constant change in power levels, and a sinking house.. this can vary.
Similarly, when I put my portable dish out the door for D2 V8s, I tune it to the Optus test channel at around 85%, but still have to rotate both the dish, and head skew to get the signal of the V8 transponder to around 58% off the same bird.
Both are better on a 65-90cm dish as apposed to the smaller 45s that some people have.
It may be that you are getting awesome signal off the NZ FV spot due to its power, but the dish itself is not quite tilted or rotated correctly.. you would hardly notice. But for the others they need to be bang on.
Its a catch 22, you may have to decide which you want the better signal of, and tune it specifically for that.. both rotation, skew and tilt.. Then see if the FV one is still alive.
Its like parabolic wifi signals, you will always get part of a signal, but the strength varies depending on how much of it is zipping past the receiver after being bounced unless its peering down the barrel.
And with skew, as one voltage is equivalent of going _ and the other | as you can imagine, to get both it needs to be bang on / assuming everything else is looking straight at the stretched out panels, swinging it slightly makes a difference to either FV/Sky... or SBS
Dammit could have found it before I wrote my epic post :)
At least my point was discovered.. its hit n miss.
Word has it the others are possibly down, I cant confirm as I do not have a DVB-S2 receiver (which is required to decode the MPEG4 streams) but the user may be in the same boat as you and not have it aligned
Cloud spending continues to surge globally, but most organisations haven’t made the changes necessary to maximise the value and cost-efficiency benefits of their cloud investments. Download the whitepaper From Overspend to Advantage now.
My SBS on Optus D1 has gone ... hopefully that is just rain fade on the 60 cm dish. At least I can still get SBS on C3 (90 cm dish) with the Aurora card.
yes I hope so too as up here in Auckland I have lost GO , Nine and GEM BUT surprisingly my favourite, SBS (both SBS 1 and SBS 2) are ok (usually these are not ok when the weather is bad)
