DTT Mt Leinster, Ch45 blocking Presely in the South East

Read somewhere that they are building mast in Arklow for DTT. Ready by end of October I hope.

Im near arklow and I can get DTT no problem with an indoor ariel (a bit of co-channel interferrence does occor on occasion however even with an indoor one) - you should be able to as well unless your antenna is pointing towards presley and its an outdoor or loft one (in that case its co-channel interferrence)

That's interesting. My outdoor aerial (VHF) is pointing towards Mount Leinster and was getting great Irish DTT until May. Now it's impossible. Others having same problem in the area

Mount Leinster was transmitting on 4 Muxes (frequencies), then in June they stopped transmitting on 3 of those muxes. Foolishly the mux the choose (Channel 45) to transmit the DTT signal on suffers from interference from Wales and is blocked out for many people on the East cost. People in Wales also have some of their channels blocked out too as a result.

RTENL could at the flick of a switch change to a mux (channel 39) that is not affected by interference but they seem unwilling to accept there is any problem at all.

When DTT launches in October you and many like will not be able to get a signal from Mount Lienster and the only reason for this is pure stupidity.

I'd suggest write to your local TD and complain about this shambolic state of affairs. You have a TV license, you have the correct equipment, you should not have to alter your set-up or pay somebody to do it change it for you just because RTENL won't flick a switch to change to the correct mux (channel 39). Spread the word to your neighbours too

You will have to tell your T.D that it is Comreg's fault and they have to give RTE a public service broadcasting licence for ch 39 instead of ch 45.
It's so easy for someone in Comreg to do that.
It was their tests up to a few months ago on ch39 that gave you the perfect reception newleaf in Arklow.
Isn't it gas that instead of just flicking a switch to go on ch39 at leinster,they are needlessly spending thousands on a new transmitter in Arklow that will only solve the problem in a maybe 3 to 5 mile radius and ignore rural south wicklow and wexford.... [and parts of waterford obviously]
Typical public money wastage....

RTE say it's Comreg's decision but who were the engineers that recommended ch45 for Mt Leinster in the first place?

No prizes for guessing that one folks...so theres no escaping culpability!
RTE could and should argue to Comreg for ch39 usage.
Even with a new transmitter in Arklow,what are the people outside the town to do?
You don't have to go far before you cannot see the cemetery industrial estate and it's so low power and with local topography,it's going to be the town only really.
What about rural areas with existing good analogue?
It's totall unacceptable that they are going to have that replaced with ropey at best and often non existent digital on ch45.

Tropospheric ducting will be fair to high from tomorrow 0600 utc up until Wed. The chances of us getting Ch 45 at all is minimal. It has almost gone as 1500 utc. Though on the other hand UK DTT should be great!

Is mount leinster on today?

It's on at the moment anyway.

Meanwhile,It may be that RTE are performing an interesting part solution to the problems people in rural south Wicklow and North wexford are having with welsh aerials..in the light of them wanting for god knows what reason to stay on ch45..

Will this not jsut lead to more co-channel interferrence or is it jsut a relay in which case it could be the same result or are tehy that stubburn to think that they can actually block out presely all together and get rte to work?

if its not a relay and its a new transmitter then would it effect our welsh neighbours or is the power low enough not to?

Arklow is very low power , a tenth of a kw I think so no that would interfere with wales Blaenplwyf over there.
Theres more chance of BP interfering with it actually especially on the margins of Arklows area during tropo.

As for Kippure...well if they can get it to service rural south wicklow,then surely it makes more sense than having overspill into clermont carns service area.

Hi all,

Can someone tell me what is going on?

Recently I have being receiving RTE DTT on Channel 54 through my 'Preseli' aerial. Like the Welsh broadcasts 54 has been coming in on my Technomate Combo at 93% quality. As this is obviously not Mount Leinster where is it coming from and also is this reception due to the current good weather? However in previous good weather I never noticed this.

Also yesterday whilst messing about with the Technomate menu I received Mount Leinster on Channels 39, 42 45 and 49 for a few minutes but it went off back to 45. Am I imagining things?

However I am receiving Channel 54.

Advices please.

Channel 54 is from Kippure, near the Blessington lakes. The footprint is rumored to be changing to cover south Wicklow and north Wexford.

Looks like you're receiving a signal from Kippure

A thread is started here about it - http://www.boards.ie/vbulletin/showthread.php?t=2056015326

Thanks charlie1966 and jobyrne30. I missed the proper thread for this and perhaps the mods can transfer?

Hi has Mt Leinster Ch 45 gone off the air? I'm getting nothing here in Tramore. There is no lift at present. It just started to come back. Must be enginering works.

jabarrett35

I just had an installer here and it transpires that my uhf aerials one for mt Leinster and the other a deflector in the area has a combiner on it which is blocking out Ch 45. He says this is going to be a problem in this area on top of Presley. He feel I would probably better off using the Dungarvan relay on Ch 62. He is coming back tomorrow so hopefully I'll get better reception of Mt Leinster and Presley with a new aerial.

Let me know how you get on. That would be a nice compromise assuming that you can get Preselli in some reliable form. I would really like BBCOne HD for my pseudo HD F1 coverage (Yes I know it will be on freesat, but I use picture-in-picture for the race from the interactive stream on a different transponder and I only have on drop into the room!)

jabarrett35

New aerial up Presley is coming on ch 42 43 46 49 but no ch 50 which is the HD muxes installer wasn't sure why. He said 100 element aerial but said leave it and see what it's like with lift. Also moved my Mt Leinster aerial to Dungarvan signal coming at 80% and 80% quality. Apparently the combiners on most houses here block out Ch 45 and you get Mt Leinster from the deflector aerial which in the wrong orientation and polarisation.

UK HD is DVB-T2
maybe your MPEG4 receiver's "tuner head" is only DVB-T (fine for nearly everyone else's HD)

DVB-T/DVB-T2 = Tuner head technology. DVB-T2 tuners do DVB-T also
MPEG2, MPEG4 etc = Video codec on the MPEG2 Transport stream from tuner head.

jabarrett35

Watty, would you sill get strenght on the signal meter or would it not register? I've Samsung Le26c350diw,sigmatek DVBR 520 and Metronic zapbox Hd I'm sure these are not DVT T2.

Gerry Wicklow

I used to get the mux on CH50 at 80%+ before they changed it to HD T2 now no signal registers on my dvb-T equipment.

watty

An Analogue signal meter will show a reading, but unless you have a channel wide filter that's no use as you would see sum of all the muxes.

A real Spectrum Analyser will show it. My 1986 Spectrum analyser (HP141T) knows nothing about DAB, DVB-T or DVB-c and can see them.

But a Digital DVB-t tuner likely ignores it.

marclt

No, you probably won't see the signal strength and the box will just skip over the channels....

Great result tho!

jabarrett35

Thank you I kind of knew I would get something because I'm quite high up and very near the sea. I'm getting over 75% strenght on most muxes. Shame about HD though. Any ideas on a good DVB T2 box. I look at the Humax.

The humax didnt do a pvr in t2 last time I was in the UK so I settled on the sagemcom.
It's quite buggy as it's a work in progress.They fix bugs as per reporting of them via and over the air software update.
I'm receiving those fine from presely.

You wont see anything on ch50 on a t1 box but once you get a t2 box,you'll have the same strength as the bbc mux on 50.

Well done by the way.Having RTE and most of uk freeview on the one epg is great.

Came across these two new Triax DVB-T2 receivers yesterday, haven't read any reviews on them yet.

Annuncement on Morning Ireland this morning that Mt Leinster may be intermittently down during the day for essential maintenance.
