Frequency Changes at Three Rock

Gyck

Is it possible to adapt or modify a group C/D aerial into a group A aerial? Assuming its a 10 Element UHF contract is it a case of switching out the PCB?

No its the length of the elements that are proptional to the frequency used . I'd try it first it may well work ok on ch 30.

Ok thanks!

Sam Russell

My neighbour has a group A aerial and is receiving 3 Rock on 54 with no problem, so I would think the reverse would apply - a C/D would be OK for ch 30. Having said that, I get it on a coathanger.:D

I was talking to the inlaws today and they have not heard anything about the requirement for a rescan..

as they told me they buy the Irish times every day, listen to the news , watch the 6 and 9 news , Nothing., no info..


(they have a saorview box)

they know now though.

Gerry Wicklow

They'll probably do one of their classics on the day like they used to do years ago..."We apologise to viewers in xyz who currently have no reception because of a fault..." :)

Sam Russell

Perhaps they consider a rescan to be normal, or alternatively, a Soarview Approved box will do it all on its own. Unapproved sets, go fix yourselves!

Notice of the Three-Rock outage next Tuesday up on Aertel 169 - http://www.rte.ie/aerteldigital/desktopxhtml/169-7.html. Note the error - 10th May, should be 10th July

The first four slides of page 169 on Dig Text mentions 9:00 - 13:00 for the 10th July for Three Rock. Slide 7 is as mentioned above. Is there a chance this was past information as times differ also?

It's possible. It could also be that the outage is shorter than first announced (and still within 0900-1400 hrs first announced last Wed) following completion of engineering work last week with the typo thrown in.

Heard an announcement on Radio 1 before the 4 pm news this afternoon advising listeners to rescan their Saorview receivers next Tuesday.

jamescc

was announced on rte about 7'30

jamescc

So has anybody's tv lost signal yet

okla

I just did a rescan and saorview is coming in loud and clear on CH 30.

Gerry Wicklow

I wish the guys in Mt Leinster would buy a watch. They pulled the plug at 08:41 this morning for a 09:00 outage. It's not the first time they've done this either.

Tony

Receiving both 3 rock and Kippure now in Tallaght on an indoor aerial.

Alun

I can get both here in Bray too, in fact when they were both on ch54 I wasn't particularly sure which one I was getting, I got a good signal just by pointing my attic aerial (group C/D) in a vague easterly direction. I've been up to attic armed with a compass, and now I'm getting a stronger signal from Kippure, presumably because of the aerial despite Three Rock being slightly closer (10km vs. 13km) and being visible from my front garden. I might pick up a wideband aerial sometime and see what difference that makes.

Any indication of a channel change for Multiplex 2 from Three Rock?

jamescc

My tv has switched over to 30 now

For anyone on UPC in Dublin, it might be interesting to keep an eye on the analogue relay of Channel Four on UHF channel 30.

Those who may currently experience co-channel interference from Kippure VHF will see that element of CCI disappear, but when the Three Rock DTT transmitter kicks in with increased power, it may create a problem.

Further to my observation, I am now noticing a significant degradation in picture quality on UPC's analogue Channel Four now that UHF channel 30 is active from Three Rock.

Issac

I've lost my saorview signal now. Nothing coming through even after a full rescan. Any suggestions? Is anyone else having this problem?

Unbelievable. Just as I say that the channels all come in on ch30 but still no picture or sound

First reported problem with the frequency change.

What type of aerial are you using? Where approx are you located?

EDIT
I see from a previous post you're using an outdoor aerial indoors, maybe it'll have to be fixed outside

Issac wrote: »

I think it should be ok if you can pick up TV3. I was in a similar position and an internal worked for me - as long as there was no traffic interference from outside. Ended up buying a small rooftop and using it inside. Problem solved.

Issac

It's a small outdoor aerial, inside our garden shed, in Booterstown. I'm getting text telling me what program is on but "no signal" is written on the screen.

Issac

Lost the signal again after trying another rescan. Just says no channels available now.

Might be worth trying it higher up, in the attic maybe or you'll have to fix it outside.

Issac

I was afraid you'd say that! Have they dropped the signal power or something? Why'd they go messing with it?!

They haven't said what they've done on Three-Rock other than change the frequency - reduced power, changed radiation pattern, new antennas???

In any case they will always recommend a rooftop aerial.

Do you know what group the aerial is - Wideband (black tip) or Group CD (green tip)? If the aerial is Group CD you have the wrong aerial for the new frequency at Three-Rock. Wideband or Group A (red tip) required.

Issac

Damn them. I just read through the start of this thread and this whole thing seems like a mess. It looks like I need a black labeled aerial for around 3 rock. Thanks for your help!

Sorry if this is a dumb question but have you tried scanning ch 54 ?

I am in Ballsbridge and I have found the signal rock solid (if you pardon the pun) with my bedroom TV giving an improved performance on the coathanger.:D. I am getting 60% on that when it was only 54% on ch 54. My main TV gets 50% signal and 100% quality.

Did they have to change the panels for such a big channel change?

Issac

I just checked the aerial there and it seems that I do have the black tipped aerial. When I look at the signal coming at ch30 it's really weak (non existent really) and the quality is terrible too. Running searches at ch54 yields no results either. Keeps on searching but finding nothing...

Verso

Hi all,

Just a quick note to say that I have re-tuned all my TVs from Ch. 54 to Ch. 30 for Three Rock and no problems.

I am in Cabinteely and in sight of the transmission masts. The quality is at 92% with a black tipped outside aerial.

Did you try moving the aerial? The 'sweet spot' for channel 30 may not be the same as channel 54.

For those who can read the TS data, does it still list 738000 as the frequency?

uck51js9zml2yt

just did an automatic retune.
everything worked fine with my little €6.49 indoor aerial

BubbleBalls

Hi All,

As with Karsini I would also appreciate if someone could confirm frequency? Looks like it has changed from 738000.

For those who dont understand the frequencies that equate to the channels.

738000 = Channel 54.

546000 = Channel 30.

Do you know if the TS still shows 738000 (and 198500)? Or is that old news?

What do you mean ?

There is (or was) data in the TS that mentioned some frequencies. It said 738000 regardless of what TX you were on. It also had 198500 in the list which is not active anywhere as it's a VHF channel.

mollser

Much stronger signal on Ch 30 in leopardstown just using a cheap indoor aerial,rock solid100%,thanksguys!

Communication was abysmal tho,surely a message could have flashed up periodically on the channels from3rock over the last couple of weeks? Only discovered this as I sat down to watch revenge and nothing there.. .

I think the problem with this is that each TX is carrying the same stream. To put messages on the Three Rock stream they'd have to demux, decode, re-encode and remux the stream. So it's more difficult to do than with analogue.

News to me. The transport stream should only have indicators for the Local Mux being broadcast. In this case the Mux frequency is now 546MHZ.

There will be no references to 738Mhz in the TS unless you are receiving from Kippure which was SFN with Three Rock, but not currently as Three Rock has moved frequency.

Perhaps this is where the confusion lies. If you are Dublin your main transmitter Three Rock has now moved to Channel 30. Rescan your TV.

Hi,

STB - thanks for quick reply and apologies if I am unclear here.

I am new to Saorview and am using a VU+ Duo (not official) to manually scan the Irish channels. My working settings, until this morning, are below. does anything look out of place? Any ideas on why I cannot get the channels at all?

No confusion. I took a dump of the current NIT to check it myself. No mention of 738000 here, it only has 198500.

All TX sites are transmitting the same TS so the NIT would be the same across all transmitters.

What has this to do with people not being able to pick up Ch30 ? The NIT may change from time to time but the the Frequency List of Descriptors that the Network uses doesn't. (It includes frequencies that are not used alright including VHF - but that is in the Saorview spec, regardless of whether they use them or not). It doesnt affect reception. Its denifitions of where services can be found.

Per your TS dump.

738 is still defined in it as it must be for Kippure.

As is 546 still defined in the NIT as it is used for Holywell and Kinsale.

BTW The confusion I was referring to was that some people on the outskirts of Dublin are under the impression that Three Rock is still on as 738 is still working for them. This is not the case, they are receiving Kippure, hence the "drop" in signal.
