    When I first watched Saorview on my Samsung LE40C750 it was very glitch, the sound would be getting very interfered and the parts of the picture would stay the same for a second while the other parts would show the current picture.

    But it was fine 2-3 weeks ago when I watched Tottenham-AC Milan on RTE2 HD on Saorview. But tonight I tuned into watch premiership highlights and the signal is glitchy again. Does this happen to anyone else?

    Happened me watching Rugby last night.Was real heavy downpour at one point and signal broke up completely.

    Happened to me too last night, but only once. Can't remember if it was raining at the time.

    Is this something we all have to put up with if weather is bad, or is it aerial problem.

    I'm getting 100% signal quality & 92% signal strength,but quality takes dramatic nosedive for couple seconds during inclement weather thus causing picture freeze/breakup.

    We'd get frequent artefacts and 'glitchiness' on RTÉ 1 and 2 (rarely watch TV3, but I'd presume it was the same).
    Anything from part of the picture freezing to people becoming green and '80's Music video' looking (leaving a distorted trail of the actors movement behind them on-screen)

    What's your analogue reception like?

    People seem to have got this idea that DTT will be reliable even with a really poor aerial setup that gives rubbish performance on analogue; it doesn't work by magic.

    I wonder does the SFN of Three Rock & Kippure fool some people into thinking they're getting good Saorview with bad analogue from one or the other (how much of an overlap is there)?

    Analogue Reception is grand - no bother with it. In north County Dublin and get all four Irish Stations without problems, clear picture and sound with no snow or breakup.

    The UK Channels also come in OK (BBC 1, 2, UTV, CH4), but about 50-75% as clear as the Irish Analogue stations.

    Glad I found this thread ...... my PC was dropping audio every few seconds yesterday, but the picture was fine.

    For the moment I will blame the transmission until I am sure.

    I find saorview very glitchy indeed, I got my signal boosted by the tv guy last week so I now have 100% signal quality but I still have the odd glitch.

    Glitchy in bishopstown cork too with my usb tuner, fine at home in Kerry and i'm a mile from the transmitter here in Cork..

    Wierd...

    Currently RTE Radio 1 is not RTE Radio 1, it is something else. The whole datastream is messed up.

    All OK here from Mullaghanish.

    I've been getting similar on mine from Kippure the last few evenings - weather hasn't been that bad. Was going to check the signal strength this evening. I'm using an edison combo, and haven't had any issues on the terrestrial side until this.

    Have noticed this a lot for the last week or so, and it's getting on my nerves now, picture freezing and breaking up. I'm under the cairn hill area. Luckily i can switch over to the analogue stations at the moment, but i'd be interested to know why it has suddenly started to have these issues. :(

    It's weather related.
    In high pressure conditions,digital tv signals travel a lot further than old analogue.
    I'm picking up perfect digital itv1 from cornwall here in wicklow tonight.
    It's also got hd on ch47 so it's bound to be interfering with cairn hill tonight.

    This is the downside of saorview and theres nothing that can be done about it.

    A lot of breakup here tonight from Mullaghanish (Ch 21).

    There are two three threads active on this at the moment, this one and http://www.boards.ie/vbulletin/showthread.php?t=2056232208 (and http://www.boards.ie/vbulletin/showthread.php?p=71593613#post71593613). No doubt there will be more threads as people switch over to DTT. I haven't had similar problems with analogue.

    This might be something the RTÉNL Saorview people should include in their info. Perhaps it could be mentioned at one of the future RTÉNL Saorview trade events.

    yeah caradon hill cornwall is on fire tonight which is definitely whats causing your mullagh break ups.
    It's causing some problems with arklow tonight aswell.

    Wonder if the forecasted Saharan Dust Plume will affect DTT/Satellite signals? (Click on link for satellite imagery.)

    How? They're the same thing albeit more tightly modulated as multiple carriers & packed into the 8MHz channel; didn't think it affected their travelling ability.

    Just to concur, picture breakup on DTT from Mulla here in North Cork tonight was brutal.
    However, as a side issue, I did a scan on my Dab tuner and got BBC national mux perfectly, plus quite a bit on fm from Wales and I must be a 100 miles from the East Coast !

    because they are cofdm which is very robust in travel versus analogue.
    You need very little signal to decode that versus analogue.
    look at the many reports here for example of poor irish analogue but perfect dtt.

    In Co. Limerick it might be more likely CCI from Divis in NI - it has analogue Channel 4 on Ch21

    The Cush, when it happens again check Ch24 analogue for any signs of a weak UTV from Divis??- as that channel is usually empty (apart from occasional DTT testing from Mullaghanish). Hopefully your TV doesn't have a picture mute on weak analogue signals.

    Divis has occasionally been received easily in north Kerry in lifts, see this reception there of Channel 4 on Ch21 (note, it was before Mullaghanish DTT launched on 21):

    One might expect some bit of interference to Mullaghanish TV3 (Ch27) at least?
    Any UK transmitter (that might reach you) that uses Ch21 also uses Ch27 ! (analog or digital). Analogue interference (on analogue) would usually cause a 'venetian blind' effect, digital interference on analogue has the same effect as a drop in signal strength (more snow/noise)

    Though when transmitters go full power in May, viewers' reception will be immune, or a lot less prone to interference during 'lifts'.

    you posted elsewhere

    All other transmitters except those with NI overspill will be going full power from saorviews official launch date [may 6th ?] which in most cases will mean a 6db increase in received signal.

    An increase of 6dB in more simple language- is a multiplying of the power by 4 - which is a significant jump in power.

    How is that relevant to causing interference, apart from the fact you need very little signal for CCI?

    It's the RF that causes the problems, whether it be multiple or single carrier (I suppose a digital multiplex would be a more efficient interferer).

    Decoding a wanted signal & causing unwanted interference are seperate considerations.

    Had that problem when my dad first got the soarview tv at christmas.

    Took down old aerial that had a perfect analogue signal, and put up a 50e one my mam had picked up in argos... or heatons can't remember which... it was tiny, like a foot long and it made the picture absolutely perfect, hasn't broken up once since.



    Also on his tv there's an option that appears to buffer the picture a bit which can cut out choppiness, too much and the audio goes out of sync but it helped a lot before new aerial.

    EDIT: actually just remembered... he setup new aerial pointing same way as old one and the signal was ****, then he pointed it at kippur after I whipped out my android phone and the layer app... inside of which was some random app in which showed you the direction of the base stations which was uber handy.

    Yes, people seem to pick up quicker on the effect co-channel has on digital, for obvious reasons, although even slight analogue on analogue is noticeable.
    If it gets like what I tuned into last night in Monaghan; Kippure & Maghera RTE1 on channel E, it's pretty much unwatchable.

    Did you have 2 aerials pointed at Kippure (VHF & UHF).

    What was analogue TG4 & TV3 like?
