[beer4life]

G,Day All,
Seems I haven't covered this one Yet. ABCs and SBSs FTA.
Beaming into Australia.

12521H 14294 DVB
12539H
12556H
12574H
12604H
12622H 12600 MPEG-2/HD
12649H
12658H

Haven't checked them yet, So don't know what "SKEW"

Kindest Regards, Bill and the FunFiles Team.

Anyone getting the Aussie beam from NSS-5 in New Zealand? If so, where are you and how big is your dish? Cheers.

From Melbourne, I've managed to pick up some of the ABC and SBS channels on my 85cm dish using my Strong 4652 decoder, but the signal strength is only about 54% at best even after adjusting the skew on the LNB. Whats more anoying than not being able to pick all the channels on NSS5, is losing most of the channels from Optus B3, C1, B1 and Pas 8 because they are now out of skew ( I have a H-H mount DiSEqC moterised dish). I'm confident my dish is tracking the Satellite arc pretty accurately because I was able to pick Intelsat701 way over at 180 East without adjusting the skew - this is when all the other satellites were being picked up also. If anyone knows why I'm having this problem with NSS5, I would appreciate the feedback, otherwise I might dedicate another dish just for it.

Congratulations, you do seem to be one of the few, that appreciate the "skew" problem.
I was banned from an ausie board 2 years ago for being arguementative about this. The resident Gurus had their heads in the sand.
Fact: Optus Sats do have a preset skew of about 30 Deg.
Fact: If you check " GorbTrack ", you'll find the observable skew changes considerably from H-H.
Fact: The rate of this change is dependent on your latitude.
Fact: To follow the "Clarke Belt Parabola" accurately, you need to select a motor with the appropriate kink in the rotor. (30 or 40 Deg. are the norm).
In other words, use a 30 Deg. one for Qld, and a 40 Deg. one for the southern States.(Not quite as critical as it may sound, but will help.
Fact: LNBs used by "Foxtel and Austar" had that skew built in. If you replaced theirs with normal commercial LNBs, you needed to skew about 30 Deg. right, looking into the Dish. If you want to look at other Sats, you need to skew their LNBs 30 Degs. left.

There are various ways of overcoming these problems which I've investigated.
You could use a motorised dish with a LNB with motorised Skew.(Not cheap).
Or: Two LNBs on a rail on a motorised dish.(Not very easy to set up).
Or: what I eventually decided was the optimum solution.

And that is two independently motorised dishes, with a tone burst contolled DiSEquC switch(provisision for 4 inputs)
Voltage or 22Kcs only interfere with the motor control.
You could of course use this to feed independent STBs and monitors.

PS, I'll check that Sat, when I have a little more time, and report.

Thanks for clearing up that "Skew" problem, much appreciated!

I think I'll try the two LNB option first and if that doesn't please me,
I'll go for an extra dish but no motor at the moment.

Cheers!

G'Day All,
My previous reply left a couple of glaring gaps, which I foresook for brevity.
1: There are Dual LNBs for two Sats, But only if 6 Deg. or less apart.
2: Depending on your Fixed dish, Multiple LNBs on a rail, probably limited to 30 Deg. spread of the Sats.
3: At my Latitude(36 Deg.), The observable "SKEW" of a Sat with Normal Skew is +/- 60 Deg. from H to H.
4: This is accounted for on a H-H motorised dish as it twists from H to H.
For fixed dishes, you must consider this if the Sat is not due N/S.
5: Due to the above, if your dish actuators are only in the horizontal and vertical plane, your Skew would be wrong for a Sat not due N/S of your location.
It was a very astute person that conceived the idea of H-H motors, with that peculiar bent rotor, that not only track the "Clarke Belt Parabola", but, to a large extent, also account for the change in "SKEW".
I do hope that I've cleared up many of the mis-conceptions and that once you understand the principles involved, you too will be confident in setting up dishes, fixed or motorised.
