Rte1 terrible on Saorview

Dempo1

Hi, apologies if this has been raised previously. I have external aerial, cable directly into TV, Have tried everything and RTE1 and RTE+1 dreadful, no other channel affected, in fact they are perfect.

One thing that I should mention , my Saorview is built into TV so not using a box, I've also seen mention of sky box near TV could be interfering so have plugged out just to check, no difference.

I'm in the Midlands so perhaps that's it but with every other channel perfect, re tuning done, aerial directions checked, I just don't get it.

Any advice appreciated

What are RTE2+1 and VM3 like? They are on same frequency as RTE1 so should be same level of reception on those channels.

Just checked and both perfect, it's just the oddest thing RTE 1 & RTE 1 + the problem, it's been like this for a long time, just got fed up and thought I'd seek advice, thanks for responding

It’s usually VM 1 channel I have the issue on saoirview, Rte1 only the odd time based on where I am. Could there be wind turbines nearby? Usually that can cause issues with saoirview.

I'm in the slieve bloom mountains, I think your correct, a mystery nonetheless, thanks anyway

Im in Donegal and have had different episodes of this over the last 4 or 5 months. Cant say if RTE+1 is affected but all other Saorview channels are working fine which is odd.

TBH I couldn't be arsed contacting Saorview about it as you are always given one of two stock replies - high pressure affecting signal or contact local installer as the aerial and/or cable aren't right.

Agreed, I'm the same and I do think it's weather related also. Only watch RTE. 1 for news anyway but can catch that on news now

There are regular reports of perfect reception on some channels and non existent or intermittent on others. This might lead to the impression that the perfect channels are very strong signals. They could be only a few percent stronger than the problem signals. There should be a menu which shows signal strength, and this would be my first port of call in trying to identify problems.

There are two multiplexes on each Saorview transmitter, which use separate frequencies. RTE 1, and 2 are always on separate frequencies, and likely not to be the same strength. My signals from Clermont Carn are 80% RTE 1 and 85% RTE 2. Plenty of signal, but if I was in a marginal reception area, I could lose RTE 1.

I’m near mountrath and hadn’t seen Rte 1 in ages due to signal. Went up into attic and did a bit of rooting around and found it was a splitter that was fooked. Perfect now. Both TVs grand now. I was blaming the weather also.

It's amazing that RTE have not been kicking up a fuss over this, I've seen alot of reporting on terrible signal for their main channel, I assumed they help finance it? the issue is very specific to RTE 1 & oddly RTE 1 +, I can honestly say I've never seen issues with other channels on this system

It's not a splitter for me, I've a direct cable from external aerial into back of TV which has saorview installed

dxhound2005

I still suggest that people go to their menus to see what are the signal strengths. The perfect pictures might be weak signals, but just strong enough.

It won't be only those 2 channels. Anyhow, there's nothing wrong with the transmitted signal; some people are just in areas where it can't penetrate adequately, or their receiving setups aren't up to the job.

I'd say that signal quality is a far more important metric to take notice of. On an arbitrary percentage measurement a signal which was 30% strength but 95% quality will usually be watchable (assuming the 30% strength mark crosses the tuner threshold for the transmission format) compared to a signal which is 95% strength but 30% quality, which might be OK but would deserve investigation.

In most cases the signal strengths of both multiplexes will have slightly different strengths with various factors causing this. Nothing unusual about it - as long as both multiplexes are above the tuner threshold in strength (ideally at least 6db above the threshold, can be tested with an attenuator) and the quality rating is high with no or very few errors then there should be nothing to worry about. Only time it could matter is in a fringe reception area which most of the landmass of the Irish Republic shouldn't have a problem with.

I also concur with Elvis that if there are reception errors on RTE1 & RTE1 +1, then all services on the same multiplex should be affected - I've never seen a case personally where a break up of some services but not others on the same DVB-T(2) multiplex occurred. Indeed it should in theory not happen given the way the Saorview multiplexes are configured (no hierarchal modulation).

Id do that except I cant see any way of doing it. Looked at various things on the menu but cant figure out how. The tv is a LG540V

Im about 1km from the local mast with clear line of sight.

For the last 2 months I haven't been able to receive any television channels on mux 21 from Mullaghanish.
This includes rte1, rte junior etc. All the channels from mux 24 are fine.
Has anyone else experienced the same or could the television be the problem?

I am certainly no expert on this , my system is very straight forward, external aerial, Coaxial cable directly to back of TV, saorview preinstalled in TV and yet RTE1 + RTE 1 + 1 remain the only channels that have regular issues. rain, sleet , snow and sunshine, calm, windy, makes no difference, all the more peculiar that every other channel perfect and all of the time.

If you are only 1km away from the mast the signal may be overloading the TV's front end. Do you have a proper aerial on the roof? At 1km, a foot of wire out the back of the TV should be enough. I am about 8km from a mast and use a bit 1.5m coax plugged in the TV. With the braid and core split two feet from the end to form a dipole.

Thanks for that. I'll give it a go later.

Yes, had a Saorview aerial fitted to the chimney several years ago. Strange though that RTE1 is the only channel affected and even then its only now and again. It can be perfect for a couple of months and then go awry for a couple/few weeks. In saying all that I wouldnt be watching the Saorview channels on a regular basis. RTE1 and the RTE news channel are the usual ones I watch.

This is quite possible. In this situation there may be an excess of signal. There is also a chance of high power transmissions for other services coming from the same site, which can increase overloading and further swamp the TV receiver.

You won't have every other channel perfect: VM3 & whatever else is on that frequency will be poor too, whenever RTE1/+1 is.

Do you know what transmitter you aerial is set up for, & can you see which UHF channels/frequencies you're getting Saorview on?

I'm in Laois, slieve bloom mountains so unsure what the nearest mast would be, my TV has saorview pre installed and I've limited menu in terms of checking frequencies etc so difficult for me to check UHF, tuning seems to be automatic when I retune etc. I kid you not re RTE1 AND RTE 1 + and of course today RTE1 fine despite high winds

Elvis Hammond

Windy weather shouldn't cause trouble unless maybe your aerial is looking through trees.

The type of weather usually cited as 'troublesome', are atmospheric conditions that allow temperature inversions to form, & cause interfering signals to travel further. Not too common in this part of the world, & when it does occur, usually affecting coastal areas more.

The Saorview coverage checker shows all the transmitter sites, & you should be able to work out which one your aerial is pointed at.

Anyone got a link to what numbers the saorview channels are broadcast on? Are they on 36, 38, etc???

The coverage checker shows the freqs for each transmitter site.

It makes no sense whatsoever that one channel on a particular multiplex e.g. RTE1 is pixellated and not another e.g. RTE2+1 on the very same multiplex. If they were on different multiplexes e.g. RTE1 and RTE2 that makes sense but definitely not 2 channels on the same mux.

I agree but that's what I'm facing, I don't understand it at all, I can say weather does have an impact if that makes sense but it remains a total mystery as to why only 2 channels affected. I wish I could upload a video just to prove the issue I have.

I have had this EXACT same problem last few weeks totally out of the blue RTE 1 totally unwatchable on Saorview. I have a tv with a digital tv tuner built in.
It seemed to correspond with the "Saorsat technical changes - 1st July 2020 "
Alas tried to re-tune the tv multiple times no Joy. I checked yesterday my other tv that I rarely use but saorview works perfect on that. So i guess its not the aerial.

Interesting, my issues far longer but I'm wondering is this something to do with the actual TV, my saorview is also built in , pre installed but I'm guessing if it was this, surely all channels would be affected?

I can assure you that it's not just those 2 channels; they're just what you happen to be watching when trouble strikes. Only way to prove it I suppose would be 2 TVs side by side, with one tuned to RTE1, & the other to say VM3.

The Saorsat changes were to parts of the transmission chain exclusive to that platform, with no bearing at all on Saorview.

Pity I've only one TV with it pre installed but will see if I can borrow another TV and revert back, thanks for that

I had the same problem for the past year. RTE1 used to be the strongest station now is the weakest. I can no longer get it with a room aerial. Regardless of what TV I use.

I've mostly given up on saorview until I wire up a aerial in the attic or better.

If I run a outside aerial on a long temporary cable I get all channels no problem.

Sorry left out some relevant info. have had both these tvs approx 5 years and have had saorview working fine on them perfectly years. Same Aerial / wire set up etc. Point to note important i left off sorry some of my other channels are bad too

TV 1:
All Saorview Perfect

TV2:
RTE 1 (Unwatchable)
RTE 2 (Perfect)
Virgin Media 3
TG4 (Perfect)
Virgin Media 2 (Perfect)
Virgin Media 3 (Comes and goes not as bad ar RTE 1)
RTE Junior (Comes and goes not as bad ar RTE 1)
RTE Plus 1 (Comes and goes not as bad ar RTE 1)

Just happened out of the blue weird. Might check connections on back of tv see if there is a problem there. Its wall mounted and its tv cable is slightly pressed against the wall at a 90 degree angle so quite possibly a problem there

The transmitters that changed frequencies for the 700 MHz clearance, switched on their new freqs about a year ago. If you're receiving from one of those, that could have affected indoor reception if your TV tuned to the new freq. (The old were only switched off in March.)

Your non 'perfect' channels are all on the same multiplex, as expected. I'd definitely check out the kinked aerial cable.

Maybe I should say that moving my aerial cable slightly brought in MUX1 on one of my TVs when it was pixellated but all channels on same mux were affected equally.

Used to have issues with Saorview, moved aerial to the attic, it's been fine since

Right you were elvis, tv co-ax pressed at 90 degree just checked there. Little bit of wiggling and its back to normal. Will pick up a 90 degree angle piece from amazon next week to allow tv sit flat against wall

It could be worthwhile to see what signal strength/quality you have on the two frequencies. For comparison when you put in the new piece. There should be a menu on your TV.

Normal/perfect pictures can be from weak signals which are just about strong enough.

Was watching RTÉ1 Monday and last night and found picture breaking up.
Have had the new frequencies for a few months now by a qualified TV Engineer.All other RTÈ/Virgin Media channels were fine.
Weather too was good.
Transmitter is around Dundalk/Greenore area I think..

Cheers

Atmospheric conditions could be causing interference problems, & it will probably happen again over the next few days.

Since the reorganisation of the UHF band, the number of available frequencies has been significantly reduced.

Mux 1 and Mux 2 broadcast on different frequencies, so it is possible that one or both could be subject to interference from another transmitter using the same frequency much further away.

Even in ordinary times, depending on your aerial and cable set up, one frequency may be weaker than another.

For atmospheric conditions, always worth checking this map: http://dxinfocentre.com/tropo_nwe.html
