    Please start a new thread in the terrestrial section with the exact model and we can advise. This thread is for Saorsat and not how to record Saorview.

    I've a couple of Saorsat questions:

    1. Can I mount a Saorsat Ka LNBF on an old Sky Astra dish (alongside the Astra LNB) or do I need a new dish?

    2. Will a UK Freesat+ HD Box (Panasonic XS350 DVD Recorder with two LNB inputs) work with one input connected to Sky LNB and the other to Saorsat LNB? I only want the Saorsat picture/sound and don't mind if I lose the teletext or EPG!

    Thanks, Paul

    PS I'm in Dublin.

    .

    1. A solid dish of at least 80cm is recommended. I would recommend an 88 or 90cm in Dublin. In theory a Sky dish might work but not reliably during heavy rain.

    2. It would need a non freesat mode and DiSEqC. I don't think the panasonic has this so no I don't think it could be used for Saorsat.

    Has anybody used the ferguson 52d for a saorsat/free to air setup.I am looking for a simple to use box that can list all channel in one list. I am not to bothered about epg .The remote looks simular to the arriva 150 which works well.

    Probably a Saorview approved combo TV? I don't think two box "solutions" are viable, especially for older folk.

    Hi, read through this and cannot see anyone raise my issue. It was mentioned that someone thought you could not watch saorsat on split signal simultaneuosly. I have done 2 installs involving 3 room with free to air and saorsat in each. The box I used is the saorsat recommended walker box. When watching the 2 boxes on the split saorsat signal if one of the boxes is change from saorsat to free to air the other one freezes on saorsat for up to 5 seconds and vice versa.
    What i have done - Astra 28.2 is fed in port 2 on 3 diseqcs, 1 saorsat feed is fed direct from KA lnb to port 2 on 1 of the diseqcs, the other saorsat feed is split and then fed to port 2 on the 2 remaining diseqc swithes.
    I have tried different combinations of diseqc far from dish, near dish, half way. The same thing happens, change from one satellite to the other on one box and the box sharing the split KA signal with it freezes on saorsat.

    You can split Saorsat because it's just one polarity and band. ;)

    I know you can split it but the way it is working for me is of limited use.
    for example, 2 people are watching boxes fed by a split saorsat feed, one of the people is constantly flicking between RTE1 (saorsat) and BBC1 (28.2) then the second box is basically frozen the whole time. Any installation I have seen where saorsat feed is split and fed to diseqc has this problem. What am I doing wrong, CT100 cable has been used for the saorsat where possible, diseqc switches and splitters have been changed out. There must be a technical reason why split KA band on a diseqc with KU is affected when another box sharing the KA feed switches between KU and KA?

    say how you are splitting the saorsat signal ie switch used, then say how you are setting the diseq bit, a and b. for both boxes

    I presume this is a mistake and you meant that 28.2 is fed to Port 1 on the 3x Diseqcs?

    Does this problem only occur with the boxes which are working off the split Ka-feed? Or does it also occur between the box fed by the single Ka-feed and the others?

    If the former, then it looks like the Diseqc signal from the 1st box is "leaking" through the first Diseqc switch and being transmitted to the second diseqc switch, causing it to switch and resulting in a loss of the Saorsat signal.

    JKII what type of splitter are you using?

    Can you link to exact make and model?

    Has it two arrows on it?

    Is it like this?
    2way%20splitter.jpg


    The glitching should not happen. I would need to test the system to confirm what exactly is wrong but I have very good ideas.

    The KA LNB gets 13V (vertical/Left hand circular) sent from either box to power up the LNB and also to select the correct polarisation.

    If either box selects horizontal (18V) for even a fraction of a second then the other box on the line will lose the signal. This seems to be what is happening. Basically the box that has just switched sats, seems to br providing 18V to the Saorsat LNB for a fraction of a second. This causes all boxes connected to the same leg of the Saorsat LNB to lose signal.

    As for a solution, well if you force the LNB to remain on 13V vertical, no matter what either box sends, then the problem should go away (unless it is a DiSEqC bleedback problem see below) If it was me what I would try, is to power the LNB from a seperate power source, and see if the problem goes away.

    Personally I would buy one of these:
    http://cpcireland.farnell.com/_/a1330/line-power-inserter/dp/SE00411

    connect the top to the KA LNB (HF+DC)
    Connect the side to a 13V regulated power supply (IN)
    Connect the bottom to the splitter (HF)

    This would supply power independantly to the Saorsat LNB thus stopping either receiver from sending 18V to it.

    If you don't have a suitable power supply you could test by using a third receiver (set to any channel that is vertical and low) and feed that in to the power input instead of a power supply. Just for testing this would prove if a seperate power supply would fix the problem.

    If the problem is DiSEqC feedback, which is might be, this could be solved by using a satellite splitter that blocks DC, and again use the power supply inserter suggested above. (Basically a satellite splitter with no power passing ability). As DiSEqC needs power to talk removing the power stops DiSEqC signals from one receiver talking (beeding back) to the other receiver. If you can't find such a splitter you could open up one and remove the diodes.

    Why this happens? Well I suspect if it is not diseqc feedback, then the receivers software is probably programmed wrong. When switching channels it should:

    1) Send a DiSEqC command to select the correct port
    2) THEN change the voltage and tone settings for the new channel.

    It may be that the receiver is doing this the wrong way around.

    Also I would normally recommend putting 28.2 on the first port of the DiSEqC switch, and Saorsat on the second. This should make no difference, but in this case it might.

    I use a proper multiswitch so this problem would be hidden to me. If I had access to two approved boxes I could do tests (I am in Dublin)

    If needed I could make up some sort of a thing that should definitely solve the problem. Ideally everyone should try use off the shelf parts to solve this.

    Again please tell us the exact model of splitter (a photo would be best)

    As Apogee says,

    set up a test

    Box 1 connected to DiSEqC and splitter to Saorsat and 28.2 LNB

    Box 2 connected to DiSEqC and splitter to Saorsat and 28.2 LNB
    Set box 2 to RTE via Saorsat

    You say when box one switches from RTE Saorsat to BBC, box 2 goes funny for 5 seconds.

    Now bypass the DiSEqC on box 2. Just connect it to the Saorsat LNB by the splitter. It should still show RTE. What happens now when box 1 changes from BBC to RTE? With the DiSEqC switch gone from box 2 does the problem not happen?

    bypass the DiSEqC switch

    Diseqc switches are not a good solution for more than one tuner input.

    Multiswitches are easier to add another tuner.

    Thanks for all feedback.
    The receivers used are
    http://www.soundstore.ie/Product/Walker-WP95SATHD-HD-Free-To-Air-Satellite-with-Saorsat/3404/2220.2.2

    I will add some more photo's/links to the other equipment used
    for now I will try to clarify some more.
    I have used some different brands of splitters, including triax, it has DC pass on both legs and frequency 5 to 2400Hz.

    I have used port 1 for saorsat, is there a reason why this would not work as well as putting saorsat on port 2?
    The problem occurs with the boxes on the split saorsat signal only.

    Also, I have ran 1 box straight back to the split KA lnb and the other through diseqc to 28.2 feed and split KA , the box fed straight to splitter is still affected by changing satellite on the other box!

    The box having a programme problem makes sense to me, changing the voltage and tone setting first and then send a DiSEqC command to select the correct port. I should be able to test this by switching from a vertical 28.2 channel to saorsat and vice versa, then the voltage is always 13V?
    these set ups are in customers houses so i may not get to check this for a time.

    Thanks again

    I installed Saorsat for myself using a 1metre dish yesterday and my signal is at 68% - 69% on my Technomate 6900HD, I am wondering if this could be improved or is it as good as I could get?

    I used a Horizon HD-S2 and had the signal at 10.2dBi. I'm not sure if this is good or not as when I aligned it before to 9east using a KU-LNB and swapped it for the KA I was only managing 64 - 65%. I guess the real big test is rain and wind as the arm shakes quite a bit in the wind.

    That suggests a software fault which might be fixed by a firmware update, assuming that is really the fault and that they would be willing to issue an update. We could put pressure on Saorview who approved the box to get it fixed.

    Either way, as I said, supplying 13V seperately to the LNB from a power supply or spare receiver (for testing) will probably cure the problem.

    You could also try another make of receiver. This might solve the problem too. I possibly could test the scenario of two other model receivers, as I have two receivers with DiSEqC.

    Ross don't make proper Freesat receivers. It's just a generic FTA (free-to-air) box, but should be capable of Saorsat reception.

    You also need the right dish & lnb setup: you won't get Saorsat with a dish that's solely set up for UK channels.

    If you are in Republic of Ireland the recommendation is to use an aerial (not a dish) for reception of the Irish channels. Please start a new thread in terrestrial and we can advise on Saorview instead of Saorsat.

    I would have put up an aerial if i was in an area which could also pick up the UK freeview channels (which I am not) hence why i went the freesat route.

    I was just wondering if the reciever I have could be programmed manually to pick up the Irish Stations, except from tv 3 which i know is not on freesat.

    You can get the RTE channels and TG4 from Saorsat but you need a second LNB and DiSEqC switch. You won't get them from the same satellite as the UK channels.

    If you you intend doing this yourself putting up a uhf aerial to recieve the irish channels will work out alot cheaper and easier than buying a ka lnb ,a diseq switch and probaly a second dish as an 80 cm dish is needed for saorsat.

    If you are in ROI the recommended setup is Saorview with an aerial and a Saorview terrestrial box. Saorsat is only for those who cannot get Saorview. It is more expensive and has less channels.

    Is the a good combo box preferably saorview approved - that this man can avail of if he was to get an ariel for saorview and to also use his dish installation for uk services? just a post note: the irish channels are on astra 28.2e but are scrambled/encrypted and thus only receivable via a sky box with a subscription

    Appologies if in the wrong thread, but I'm trying to help my landlady save money as she's finding it hard to afford Sky. She has 2 boxes both Sky+, one in the living room and one in her room. She asked me if she could get a non sky box and still have a selection of channels. She tends to watch comedy and soaps so not worried about sport or movies. What's the cheapest way of doing this ? i.e. box, switches LNBs etc ? For a start she's not too worried about only having the one box in her room for now, as she can still watch her soaps on the sky box downstairs without a subscription. TIA :)

    Replace the Sky+ boxes with a Freesat+ receiver (built in recorder) downstairs and a standard Freesat zapper box in her room. Same dish and cabling.

    Normally you need a min of 80cm SOLID dish (I recommend 90cm min) and in some areas 1M, so check your area on the Saorsat dish size map.

    Then normally the LNB's should be both slightly offset, although RTENL recommend the Saorsat LNB at prime.

    Ideally set up Saorsat on it's own first, and then work towards a two satellite setup.

    My recommendation is to set the dish up with say 16 East at prime, then get Saorsat at 9 East (with the special KA LNB) and then Astra at the other side of the centre. It's quite tricky to do. http://www.rtenl.ie/wp-content/uploads/2012/03/RTÉNL-SAORSAT-FAQs-Mar-2012-Rev-1.1.pdf

    Depending on your offset bracket it might not be possible to put two LNB's either side of prime. Normally Saorsat is slightly closer to prime.

    That bracket assumes one LNB will be held in the centre of the dish, and the other one will be offset. If using that bracket you have no choice but to set Soarsat 9 East as the prime, and then mount 28.2 offset until you find the UK channels. If it had 3 rings you could mount a "dummy" LNB at prime and not use it.

    If you dish is only 80cm, then by my calculations, in the past, the signal on the UK channels may be a bit weak (depending on where in Ireland you are) so you may see breakup during very heavy rain etc. Even with a 90cm I would recommend offsetting both LNBs but with that bracket it's not possible.

    I have a couple three holder versions of that holder, unused, and have installed a couple, but not for Saorsat. If you can get the three holder version, centre on 13e, and get yourself an extra set of channels, you may need some slim lnbs though.

    its not as easy i thought.

    the dish i will be using has a lnb holder in the center and then you attach this mount , and start fiddling. I best have a go at trying this myself before i start the other job.

    So best bet is center align the dish to 16E and work from that.

    It depends on your needs and budget. A triax TD88 with it's multimount is not the worst. There are better makes but more expensive.

    The dish and long multi LNB arm are in this catalogue
    http://www.triax.co.uk/upload/section_satellitereception(1).pdf

    Last page 300727

    Depending on the make and type of your current dish something might be available. There are lots of multi LNB mounting options. Just make sure it covers a 20 degree arc (it needs to be long). If you already have bought the arm then it's probably worth a go.

    Can Saorsat be picked up in Liverpool? If so, what size dish?
    I doubt it. It uses a spot beam which means some parts of Ireland can't get it.

    Thanks for all the help guys, got a soarsat signal while testing locations for the dish at the weekend.

    There was a concerted effort made to receive it in Manchester, and while there is a Saorsat signal, the corresponding spotbeam from Scotland obliterated it. Whether Liverpool would be sufficiently west of the Scotland beam to escape is very hard to judge.

    I don't think any size dish will work. There is a jamming beaming coversing Scotland and liverpool.

    I did tests in North Wales and even east wales is a no go:

    Have a look at my report here:

    Summary is no hope for liverpool unless jamming signal is turned off.

    Thanks, ZG. It was a family member who asked about it. Mainly for the Irish sport. Gets that from Premier TV at the mo.

    It's not Jamming, it's frequency re-use for Internet by Satellite. But same result.

    Even if not all carriers seem to have data at any point in time.

    Eh no. The scottish beam was sending a blank DVB-S signal (as confirmed in Manchester) as opposed to the DVB-S2 Saorsat carrier. The frequency was not being used for internet. It seems as if it is deliberate jamming. The signal I also picked up near London (french beam) also seemed too narrow to be an internet carrier.

    The carriers can be any width and with few subscribers it makes sense to save power by using less bandwidth.
    The Satellite has 82+ spots and ONLY uses 2 bands of frequencies and 2 polarities. It's mathematically proven you only need four "parameters" / "colours" to fill in any arbitrary "map" without any neighbouring interference.

    The behaviour is "by design", it's reselling capacity for TV that was an afterthought.

    Also to enable monitoring and other political issues unconnected with Saorsat or Ireland you really need all spots to be active and most of the equipment in use even if only narrowband.

    Unless you have a document from Tooway or Eutelsat it's totally misleading to call it Jamming.

    This was all explained before the satellite was live. I met personally with Tooway people long before any TV usage was suggested.

    I explicitly explained within minutes of the original announcement that a giant dish would never work outside main area as a natural consequence of how the system achieves x20 capacity.

    Originally published December 2010 and comments here explaining it date to July 2010

    A manchester guy tested the signal and confirmed it was DVB-S with no data, hence a deliberate jamming carrier.
