    Mallusk should be fine unless they are lying about the Spot. Better than Ballymena, which should still be in main service area.

    So I agree with Apogee. Either you are doing it wrong or the LNB doesn't work. Or else they turn it off every time you go out to look at it!

    If you can't find it with a Prodig in spectrum mode, you're not going to find it with any other meter. Put it into spectrum mode, and set the LO to 0MHz so that the frequency range is in IF mode (900-2100MHz). For NI, you should see the data peaks for the Blue or Purple spots.

    kasat_foot.jpg

    For the Blue spot, the data carrier peak is at 19.731GHz or 981MHz on the spectrum. For the Purple spot, the data carrier peak is at 20.118GHz or 1368MHz. These peaks are always on - if you can't see either of these, then something is wrong. You can check first that the spectrum is OK by attaching a Ku-band LNBF and you should see peaks for Eurobird 9E.

    Just to show that even an analogue meter will work, you can see if I push/pull the LNB arm or push/pull on the edge of the dish, the meter reacts.

    quick update 1:30 this morning cloughmills on an 80cm dish - saorsat! !!!!!

    carrying out more tests today around no with different dishes - will post pictures and info later

    key was puttting the lnb horizontal!

    Which LNB, and which way up horizontal?

    Must be an alignment issue as the transmission is Left Circular polarisation.

    Congratulations :)

    I think he means he put the LNB lying flat, rather than on its side like he was doing previously - probably aimed too high above focal point of dish.

    Yes, certainly on my Triax bar, it needs to be flat or one port is too low and the other two high. Strangely on the Hughes LNB I have both ports (H and V) seem active at same time on 13V or 18V. Also attempting to block either with a metal plate increases the output level. Very odd. Anyway I still have been unable to go and look at it since 5th or 6th of June 2011.

    What happens in the areas that have a clash of two signals? e.g. the purple and blue areas of NI and Donegal.
    Do you guys think SaorSat will be up and running by the end of 2012?
    Is Saorsat a part of the digital switch-over requirement from that EU law or is it just a bonus thing?

    Nothing. In overlap of different "colours" you have a choice. Likely the "blue" and "green" N.I. and Welsh spots can be got on a bigger dish as far as Portliose or Athlone. Maybe even the Orange beam with a big dish in Dublin. It's spots of SAME colour with similar level signal that's an issue (which is worst half way between two identical colour spots).

    Saorsat is just a bonus.

    Actually even the Analogue Switch off isn't law, and the "real" EU recommendation is by 2015.

    Technically there is nothing legally stopping Ireland having NTSC colour 405 line TV on 185MHz and Secam 625 line on Ch 40 forever. Comreg regularly does "their own thing".

    MMDS (it's LTE or WiMax elsewhere)

    Interestingly on the tooway coverage checker it recommends some Pembrokeshire addresses use the Irish spot. So I'd say there would be coverage across West/SW and NW Wales Wales at least. Possibly over towards Cardiff without there being any interruption from Calais.

    :D Congratulations to user dbcool on tracking down the Saorsat signal! :D

    I live in a "marginal" RTÉ reception point of south Belfast. I have been advised that my location is just too far away (36 miles) from the nearest transmitter at Clermont Carn in Louth, to receive its digital signal output (both now and after switchover.)

    I was hoping with dbcool's good news, that one of you chaps might perhaps like to lend a generous helping hand to me? ;) I am no techie by any means; however I do hope to be getting set-up assistance from an experienced contact in the TV trade. (So clear and simple instructions for me to relay would be greatly appreciated!)

    I am very interested in getting a multi-feed satellite dish set-up, with LNBs aligned to the following:
    • Astra @ 28.2°East
    • Astra @ 19.2°East
    • Hotbird @ 13.0° East
    • **Ka-Sat @ 9.0° East**
    I envisage the following equipment set-up:
    • 90cm Solid Dish (Fortec or Triax brand.)
    • Technisat HDFS HD Receiver (or another recommended brand anyone knows?)
    • Multi-switch unit (to enable a feed to x2 receivers).
    I've been monitoring the vast number of technical forums and websites out there which have been covering this subject; since the launch of Eutelsat's Ka-Sat antenna last December. I understand that the sticking point for enthusiasts (like ourselves), is the lack of Ka-Band equipment (i.e. LNB's more specifically).


    I’ve read in a previous board post here, that a successful temporary work-around to this problem has been achieved with an “adjusted” Ka LNB purchased from eBay. I've also read that removing a Ku band LNB feedhorn can work too (although it leaves the unit very susceptible to rain and bad weather) – is this all correct?

    I know I’ve gone in to a lot of detail here chaps; however I thought it was best to give you a full run-down on where I am (or not as the case may be) at this. If anyone fancies taking on this project with me, or can offer any help, guidance or instruction, I would be very grateful!



    I look forward to hearing from you very soon.

    Warmest Regards,
    Allan

    No, it can't. A Ku-band LNBF is for Ku-band only and cannot be modified to work on Ka-band.


    Some of this I've covered in the PM, but for 4 positions, you're going to need a 16x sat input multiswitch. 3 of those will be redundant for Saorsat, but you can't buy a 13x sat input multiswitch AFAIK (you can get 13x input switches but they are 12x sat, 1x terrestrial).

    http://www.emp-centauri.cz/products.php?id_kateg=5&id_pkateg=14&id=248

    [edit] You could get away with a 12x sat input multiswitch, if you were willing to sacrifice one of the bands on 13E or 19E and use it for Saorsat for example - there's not much on 13E/19E of interest anyway.

    I want to just mention that Clermont Carn will be receivable with an appropriate outdoors aerial in most of south Belfast when DSO takes place. Assuming there's no large apartment block or suchlike to the south across the road from you! If the RTE signal is good enough for some sort of Aertel (teletext) then I would expect it to work. Certainly, Freeview is already receivable in Dundalk with a good aerial and that's with even longer distance and crucially far lower power than Saorview will be next year.

    todays findings - we have a temporary test rig - a ground mount wiht a td78a and the ka lnb taped on - workign fine in cloughmills - moved it to mallusk and couldn't get it working ( prob user fault only ) moved it back to cloughmills and working prefectly - a thing i've noticed - on all the screen shots of reviers receiving it - each one uses a different transponder number so a blind scan is essential to find it and whats really strange is that we are using a spiderbox hd and its pulling in only 10 % quality but the picture is 100% - even tonight in the rain - it never broke up and it was pretty heavy!!!! yee ha! - we are currently trying to fabricate a proper holder for the lnb coz this is the only way we will be quickly able to get this test rig from place to place.

    yes we had to lay the ln on its side to make it work


    and guys thanks very much for all your help - wouldn't have got this far without this board!

    Is this the first time ever that an LNB of this type will be manufactured and used to recieve the type of signal being used in the Saorsat broadcasts - does this explain the lack of availability of these LNB's - i.e. have they never actually been used or manufactured before ?


  • #1368
    Apogee
    Registered Users, Registered Users 2 Posts: 3,802 ✭✭✭Apogee


    In a word, yes. Ka-band for DTH transmission is a novelty in Europe. However, the basic, underlying technology is not new, and Ka-band circular polarised LNBFs are widely used in the US. But the LNBFs they use are very complex and designed for reception of satellites from multiple orbital locations and therefore are impractical for use in Ireland.

    Unless other countries start using Ka band for TV then is there any reason why anyone would bother manufacturing LNB's for such a small market :confused:

    Surely even if/when they do they are going to be hideously expensive ?


  • #1370
    marclt
    Registered Users, Registered Users 2 Posts: 848 ✭✭✭marclt


    Won't the LNB be the same for tooway broadband, just it's sending a signal to a sat box rather than a modem?

    If they are expensive, this might be where a subsidy for switching over those in area's where RTE aren't upgrading masts will come in...

    Wouldn't it be fair to say that if RTE are supplying you with analogue tv, then as a licence payer you would assume they should provide you with digital... hence the need for a satellite(!)

    Registered Users, Registered Users 2 Posts: 32,417 ✭✭✭✭watty


    No, the Tooway LNB isn't separate. It's integrated inside an ODU (outdoor unit) that has filters, polarisers, BUC (Block Up Converter = Transmitter).

    They will not be hideously expensive. As said earlier on the thread there will be ample quantity of Domestic LNBF (integrated polariser and feed horn) for regular dish at a reasonable price.

    The DirecTV LNBF system is for a proprietary satellite system and receiver IF. It's no use at all here really.

    People should wait for correct LNBF unless dedicated hobbyists.


    Note though some people will lose Analogue and not get Digital, that already the Digital coverage actually exceeds Analogue. Saorsat is thus a "bonus" for the 10,000 to 45,000 households that will get no DTT.
    Note
    About 250,000 households don't receive Analogue TV3
    maybe 80,000 households can't get Analogue TG4

    Today less than 45,000 households should be without DTT

    That would be the "soon to be released" domestic ones for Saorsat. Not ill-suited hacked LNBs from ODUs bought off eBay, from Hylas Hughes, Hughes Net, Wildblue or Tooway gear,

    Sure if you are very fond of microwave plumbing and experimenting buy something less than suitable from eBay. It will not work as well as the "proper" domestic LNBFs. "Coming soon" :)

    I'd be fairly sure I.O.M. will be fine for reception. Unless you are in a hole in ground on North West of Snafell.

    Fortunately I'm not in a hole in the ground on the side of Snaefell, but have a good clear view of the skies from here. :) We waited what felt like an eternity for the launch of SV so I won't hold my breath waiting for RTENL to announce the launch of SS and the availability of certified / suitable equipment to receive it. Only hope I live long enough to witness it! ;)

    If you can hang on there till late Autumn Peddyr! Probably before end of 2011.

    I moved to this Glorious Republic from "UK" in 1983 and didn't have BBC till I think 2000 via Sky and later ITV joined. In 1983 we had 1.5 channels via very poor fringe VHF reception.

    Waiting since 1999 for Irish Digital Terrestrial.

    During 1970s I listened to Manx radio regularly on an attic aerial made of cut up TV coax and a German VHF/SW/MW/LW valve radio. Near mouth of Belfast Lough in Co. Antrim.

    Years later I've chatted to Manx Amateurs via their Repeater in 145MHz band from near the Beach in Millisle, Co. Down with a 10W mobile radio and 1/4 wave whip. Must have been 2005 +/-

    I have a Gibertini Cassegrain 60cm (CPR 60cm) I bought from Slovakia lying around with ages which I never tested, so decided to give it a go today.

    This is what it looks like with a Universal LNBF installed

    From front
    lidldish_wildblue_front1.jpg

    With subreflector installed
    lidldish_wildblue_front2.jpg

    So having aligned it on 9E, tried the Wildblue TRIA as it has a proper integrated depolariser and feedhorn. A somewhat "non-standard" installtion of the LNBF
    cas_wildblue_rope.jpg

    Side on
    casdish_wild_side.jpg

    And with the plastic cover attached - fairly discreet, esp if you painted the cover
    casdish_wild_coverjpg.jpg

    Signal lock no problem, just a different frequency to the Hughes gear as the LO is different
    screen_kasat.jpg

    If anyone is interested in the Wildblue TRIA for testing with Saorsat, I'm selling it on Adverts - already have way too much satellite gear cluttering up the place.

    Question in the Dál last week on Saorsat and areas that will not receive terrestrial TV after ASO.
    Telecommunications Services
    Wednesday, 22 June 2011

    124. Deputy Éamon Ó Cuív asked the Minister for Communications, Energy and Natural Resources his plans or those of RTÉ to inform the public of their options in areas in which RTÉ intend abandoning its present broadcasting network in late 2012; the location at which satellite is proposed; and if he will make a statement on the matter. [16640/11]

    Minister for Communications, Energy and Natural Resources (Deputy Pat Rabbitte): RTÉ is an independent national public service broadcaster whose remit and obligations are set out in the Broadcasting Act 2009. In relation to the broadcasting network, section 130(1)(b)(i)(II) of the Act provides that RTÉ shall provide a digital TV network by 31 December 2011 capable of providing coverage to the same extent as its existing analogue TV network.

    While I have no function in relation to the development or operation by RTÉ, or its subsidiary RTÉNL, of its broadcast infrastructure, I understand from the company that the analogue TV network uses 150 sites and provides 98% population coverage. I also understand that the RTÉ digital terrestrial television (DTT) network, which launched on 26th May 2011 and is providing the Saorview service, will also be capable of providing 98% coverage from 51 sites.

    In relation to the proposed RTÉ Saorsat service, this is a satellite-based broadcast service being developed independently by RTÉ on a commercial basis and the service is currently undergoing testing by RTÉ. I understand from the company that, once established, the service is expected to provide ‘free to air’ TV reception of the RTÉ TV channels to virtually 100% of the population. The provision of information to the public in relation to the Saorview and Saorsat services is a matter for RTÉ. In that regard, since the national launch of the Saorview service on 26th May 2011, RTÉ and the other broadcasters have been operating a substantial Saorview information and awareness campaign to inform the general public about the availability of the new national digital TV network. In addition RTÉ has established a dedicated website – www.saorview.ie – and a telephone helpline to assist the public to access Saorview.

    In addition, as Minister with responsibility for broadcasting, I have promised to deliver a substantial information campaign on the switch-off of the analogue signal and the necessity for the digital switchover. This information campaign, which is currently being developed by my Department, is planned to launch in October 2011. The aim of this campaign will be to ensure that TV households throughout the country are made aware of analogue switch-off and of the range of options available to them for going digital.

    In conjunction with this, my Department is also currently developing plans to ensure that a range of practical assistance is made available, in particular, to address the particular needs of vulnerable households as they prepare to go digital. In this context, the expertise and local knowledge of the many voluntary and charity organisations around the country will be of critical importance to ensuring the success of the switchover process. I have asked my Department to ensure that, to the greatest possible extent, these organisations play a major part in our digital switchover information and assistance campaign.

    http://debates.oireachtas.ie/dail/2011/06/22/00105.asp#N2

    He didn't answer the question in relation to the location of the satellite that will carry the service. I don't think either RTÉ or the Dept have ever officially indicated from which satellite or position the Saorsat service will be available since it was officially announced last July.

    Hi all,

    Is Ka-Sat Tooway service being provided right now across Europe? in countries where they need a license are they already registered? e.g. Spain, Italy?

    Thanks in advance for your comments.

    Yesterday a digiweb contractor installed a tooway dish on my building for two way internet access. It seems to be the latest version. It is different to older versions. It only has ONE cable between the box and the dish for two way internet. This cable connects to the TX port only (the RX port still has it's blanking plug fitted).

    While aligning the dish he told the box inside to enter alignment mode and the LNB thingy outside itself started beeping and when the beeping was continous then the dish was aligned.

    It was EXACTLY the same as this youtube clip:

    http://www.youtube.com/watch?v=M5xSWEP3Pyw

    He selected the purple beam. All other steps in the video are identical.

    The question I have is:
    1) Has anyone used this newer version of the LNB to pick up saorview?

    2) As the RX port is now free (but seems to be fitted) can I just hook up a DVB-S2 box to it and receive RTE

    3) Do I need to also send 30V/24V up the RX line (the tooway box sends up 30V)

    4) Will I damage the LNB or my satellite receiver if I put up 18V or the LNB puts back 30V down the line to my receiver box?

    Please only comment if you have used these newer tooway LNBs that have a beeper inside for allignment.

    Thanks for your advice

    You just need to put a splitter in the cable, one port with DC power passing from the Tooway modem, and power blocked on the other port to the satellite receiver.
    Similar to page 15 of the installer's manual. Eventhough they show a 2-cable setup, the principle is the same.

    P.S. If you put a requirement that "only comment if you have used these newer tooway LNBs that have a beeper inside for allignment", then you're going to be waiting a hell of a long time for anyone to reply.

    That's perfect. I already have such a splitter, but not a HD receiver. I will try borrow one. I like this design as it doesn't put me at risk of damaging either box nor tooway equipment.

    So basically still no conenction to RX port? Is the RX port good for anything?
    Can this LNB also be used with older two cable systems?

    *Make sure* your splitter has power blocking on one leg/port. A standard splitter (all ports power pass) will cause damage to the receiver and/or TRIA.

    There's a good chance the RX port is active and you could hook it up directly to the receiver. But to be on the safe side use the splitter to prevent damage e.g.

    Tooway TRIA RX -> IN PORT -> OUT PORT (Power Block) -> Receiver

    Thanks for the help. I have the correct splitter with the red line etc.

    I looked at the installer manual and I am still not 100% clear. At least if I use that power blocking splitter, it's extremely unlikely I will damage anything.

    From the installer manual:
    RT4000N-010:
    - 300-800MHz Rx, 1800-2300MHz Tx (1
    connector)(2 connectors at the beginning)

    RM4100N-010
    300-800Mhz RX
    1800-2300 TX (1 connector)

    IDU with 2 IFL cables for services including broadcast functions
    (Capability to connect separate Ka band receiver)
    - RM4200N-010:
    - 1000-1500MHz Rx (1 connector)
    - 1800-2300MHz Tx (1 connector)

    So there is 4000, 4100, & 4200. My unit is a 4100 so I expect the signal I want is in the range 300-800Mhz on the TX line, which is not what I want.

    My satellite receiver will only receive 800-2100Mhz or so. The 4200 is the only unit that seems to receive in the range I need. So my understanding is I need to connect the satellite receiver to the unused RX port of the LNB. I am still not clear if I need to supply power to the RX port, so for safety's sake I will block the power going up/down to the LNB. I will need to run a new cable to the RX port and test the setup.

    I just measured for DC voltage on the RX port with a multimeter and it showed 0V. I think it's the RX port I need. I will initially put 0V up and see if I can get RTE, then I might try 30V

    In the two cable version is 30V sent up the RX cable too? If someone in Dublin is willing to loan me receiver (with deposit) PM me.

    For these setups, power to the TX port powers the entire unit. No power required on the RX port, so use splitter to block it.

    To be honest, having read what you've posted about the RM4100 unit, you're probably wasting your time. It looks like the RX LO is either 19.4GHz or 20.5GHz, so the output is on the B-band rather than on the L-band.

    You can buy DirecTV upconverters which will shift the B-band output up to L-band for the receiver, but nobody seems to know how to get them to switch on.

    The RM4200 model is the one you want, with RX output in 1000-1500MHz range.

    Thanks Cush, I already know the distributor as I am using them myself but was wondering if they are actually licenses by the Spanish regulator - I don't want to use this service and then discover that I need to license it

    I'm not 100% sure what you mean.

    Are you referring to an individual user requiring a licence to uplink and downlink from the satellite? If so this part of the spectrum is licence exempt throughout Europe - 19.7-20.2 GHz (down) and 29.5-30.0 GHz (up)

    I have a different model of upconverter, which may work, but I want the least number of unknowns for a new setup. As the 4200 version will work, but I don't have one, I might just see if the RX port has the different output frequency I need. I have access to a spectrum analyser which might be the way to go.

    Another idea is to disconnect the TX lead and feed 30V into it. I assume all three indoor boxes (4000, 4100 & 4200) all use the same LNB and tell the LNB which frequency to output, or else the RX port outputs a higher frequency while the TX port simultaniously downconverts to a lower frequency.

    I searched all over the net but could not find a detailed spec of how this new unit works so more testing needed. At least the dish points the right way! If I can get my hands on a HD Sat box I will test and post results. It looks as if this setup might give internet or saorsat, but not both at the same time!

    Sorry, I picked this up wrong. I thought the R4000, RM4100 were models of LNB/TRIA, but they're the modem models. So maybe the TRIAs are the same, and it has 2 different RX LOs.

    OK then, leave the modem attached to the TX port, fit your cable with DC block on the RX port and plug it into the analyzer, and see if you can see a peak. An analyzer will tell you much quicker than a receiver will.

    Sorry for the confusion, yes you are correct that part is exempt. I'm asking about the tooway operators in Spain whether they are licensed for ka-band VSAT services? I understand that the operator needs a general authorisation and a VSAT ka-band license. I'm pretty sure they have a general authorisation , but not certain if they are legally providing ka-band services?

    Thanks,

    I would assume the 5 Spanish providers have the necessary licences - http://www.tooway.com/Purchase/(country)/Spain

    >but nobody seems to know how to get them to switch on.

    A work round is here:
    http://www.m0dts.co.uk/datv_converter.htm

    but it is based on narrowband (430Mhz only) upconversion. He too could not figuire out how to enable the unit but bypassed the on/off feature.

    The last two photos are the relevant ones. Hopefully this won't be needed.

    I started looking in to Saorsat as an alternative to Saorview at the end of April; after I was advised that my ‘marginal’ location in south Belfast, is too far north to receive the digital terrestrial signal from Clermont Carn (both now and after DSO.)

    I contacted Eutelsat UK regarding reception of the Eurobird™ 9A (Ka-Sat) satellite. They subsequently referred me to the RoI distributors section of the Tooway.com website.

    Today I enquired with my nearest distributor (Digiweb Ltd in Dundalk) about purchasing a Tooway satellite dish and Tria, for the purposes of obtaining Saorsat. The Sales Representative I am dealing with is currently awaiting some information from their technical support section. It seemed to me that their technical support staff were fairly au fait with Saorsat enquiries, as they seemed clear about the details the Sales Rep relayed on my behalf. I’m expecting a call-back with (hopefully) some reasonable figures on pricing the kit.

    With this in mind, and looking at the forum posts to date, would I have success with the following set-up:
    • Tooway satellite dish
    • Tooway Tria
    • 2-Way Satellite Splitter (Leave DC power to Modem port live; but block power on other (to a Linux receiver.)
    If workable, here’s me next query:

    Could I attach a standard Multi-Feed LNB bar/holder to the Tooway Tria (or that area), in order to include Ku-Band LNBs aligned to:
    • Astra 28.2°E
    • Hotbird 13.0°E
    Linux Receiver:

    What would be the best budget Linux receiver? I’ve seen the following names on various posts, and would appreciate some feedback:
    • VU+ Duo
    • VU+ Solo
    • Spider Box
    • Az Box
    • Q-Box
    I understand that whatever STB I choose, it needs to have a D1.0 or D1.1 DiSEqC switch.

    *As always folks, any help, advice or instruction that can be offered, is greatly appreciated here!*
