    It's weird though. At those EIRP levels one would expect a 75cm to work OK, not so?

    Is it the technology they are using that maybe demands greater carrier-to-noise ratio (i.e. bigger dish)?

    It's due to the encoding used. It's not the old-fashioned DVB-S QPSK, that we have been accustomed to but DVB-S2 multistream, which is using 16APSK encoding with an FEC of 8/9.

    In a nutshell, the combination of 16APSK and an FEC of 7/9 requires a far higher signal level and quality than we have been used to.

    DVB-S2 allows for more complex encoding systems. The advantage for satellite operators and service providors is that this in turn allows more channels per transponder, and in the case under discussion, multistream. It's all a matter of economics and profit.

    I posted a link or two in another thread, which led to a discussion of the constraints when using this type of encoding.

    These might help .... and .

    Those are full power EIRP. Not all broadcasters crank out full power and for various reasons there have been issues with the closeness of 164E and needing to adjust levels to avoid issues. As for Channel 9 someone said they use 6 meter dish to downlink this t.p they are using on IS19. Its quite likely that soon they will drop the power down to make it more unfriendly to hobbyist viewers.

    I got sick of Losing the V???? on this bird on V so I stuck a new Quality 1.2 Dish. No problems

    That would be typical of Channel 9. Just how many people are out there that have the equipment to do this, not many in the grand scheme of things.

    The point is the signal is not intended to be received directly by the public.

    and you don't make it easy with 75cm dishes and any old satbox
    this and the abc s 1 makes it sufficiently difficult by finding 1 of the few satboxes that do multistream once you've got stable signal and the abc by using s/r of 47288 when most sat wont go above 45000

    I am rather surprised its not encrypted to make sure only those who need to can access the signal.
    I stand unequivicably behind everything I say , I just dont ever remember saying it !!

    Exactly. It's the strategy they employed 20 years ago (their channels were E-PAL on analogue). Just encrypt the channels again.

    But, they were also on the lower power transponders on the Aussats.

    There really isn't a problem.

    The signal under discussion is a network feed and as such is not intended for reception by you and me.

    That some people can receive and watch is their good fortune and those who can't should stop complaining.

    Not all signals transmitted on satellite are for the convenience of the public but are there for other specific purposes.

    And yes, the network in question does use a 6m dish at at least one of their receive locations (in order to ensure reception of its interstate feed under all weather conditions).

    12550 V ' A15K-1 currently running Reuters feeds.

    Also today Wizzie TV 12557 H all 22 channels have become encrypted again in the last hour. I guess they've paid the bills.

    I could easily find an address that is or register as a traveller but again I would then have to buy a VAST receiver or CAS which I'm not prepared to do. I've just spent $70 on the FreeSat before they moved Channel 9.
    Have a 1.8 dish on D2 which I'd planned to use for Channel 9.
    I don't watch very much FTA but it's the Ashes next summer.
    Looks like I will try the LNB from my 90cm.
    Update
    Tried the NBN dish and no go for Channel 9 vert's. Switched over to D2 which works well.
    Moved my 1.8 because it was looking at big trees when I realigned it with IS19.
    With a lot of fiddling I managed to get Channel 9 vert.( as someone said very tricky to tune ) but the picture looked as if it was made up of multiple images. From what I can see it looked to have Perth TV as well as others. Is this what it means to have multiple streams?
    I assume that I need to put in the pids for each channel, but the Freesat V8 Super doesn't seem to work when I use the search function. From LynSat it lists Audio pid as 720E.Which means what?

    If you're not using a receiver that's capable of decoding 16APSK encoding with an FEC of 8/9, then you're wasting your time.

    I do not believe it will as it is not multistream capable (See what mtv said).

    You require a receiver such as the DVB-S2, Multistream, 16 QAM satellite receiver referred to in the document at

    From LynSat it lists Audio pid as 720E.Which means what?
    A letter in the audio pid column indicates language, i.e. E=English, S=Spanish and so on.

    Looking at the link for a multistream receiver I see that it specifically species multistream not just 16ASPK.
    So looks as if I have a spare receiver for sale. Bugger!!

    You apparently missed the thread on DVB S2 Multi Stream Receivers here at Austech. SEARCH for it for more info.

    Also, there is a discussion regarding Multistream over at Sat Universe. Go to the the site and SEARCH for "Multistream Satellite Channels" in order to get some additional background information. Other European forums have similar information. Use a search engine.

    Note that the cheapie receivers that apparently resolve some Multistream channels are not suitable for resolving others.

    Edit: Apparently the Freesat receivers will NOT do Multistream - see the .

    The simplest and cheapest encryption is to reduce the power levels. When you are talking about 6mt dishes being used to receive these services at the tv station, dropping it down a couple of dB will see no real signal level drop there. but make it near impossible for a 90cm to lock.

    I suspect the ONLY reason it has not happened as yet is because there are a couple off Ch9 techs who want to monitor it at home😄

    Ch 9 are fully aware of the satellite hobby community receiving these chs, They tolerate but monitor the situation. the issue is copyright legality, , regarding to advertisements and news articles infringing on black spot areas etc. (these are areas not intended to receive these chs. Advertisers and their clients can be very anal about other companies accessing their marketing zone. Also some state have different crime and victim disclosure laws and naming of both. Both areas have been a thorn in the side if tv networks and the main reason why state based authorisation was put into place with Aurora and now VAST.

    In the ideal world, we should be able to have national access to all chs but it ain't that simple.
