Which locations are transmitting MPEG4 test?

ianx

Folks,
I'm trying to determine which of the RTENL masts are now carrying DTT (or at least test signals). I live in the Kilmacanogue area and have run some limited tests without success. The next step is to put a mast up but I dont want to do that unless there are signals from Kippure and maybe Kendlestown/Greystones.

Three Rock is not a runner because of a large hill.

Also is there any likelyhood that Digital will be carried on VHF (the only analogue I can pick up easily).

Thanks for your help.

Digital will not be carried on VHF

UHF only.

DTT is now being broadcast from Greystones.

I haven't been able to see any DTT signal from the Greystones relay since I installed my rooftop aerial before Christmas. Still no signal today on the allocated CH52, 56, 66 or 68. I can see the relay tower from my house and I get crystal clear analogue signals.

From Three Rock I can get Mux1 on CH54 and occasionally they broadcast the "R&S Channel" on Mux2 (CH58). This is a short repeating segment showing components being installed on a circuit board. Mux 3 (CH61) shows a carrier only occasionally.

In the short and most likely medium term yes; we do however have international clearance for a series of regional SFNs on European 7MHz VHF channel alignments.

From putting together info on here...

* Three Rock (appears to be a high powered service w.r.t. analogue coverage area, estimated guess at ERP of 10kW, but cleared for even higher.)
* Clermont Carn (separate aerial used for DTT broadcasts than those used for analogue TV, signal towards the north very restricted.)
* Mount Leinster (Not thought to be running at a high enough significant power compared to its UHF analogue broadcasts, but certainly available.)
* Dungarvan (Claimed by RTÉNL, no proof of reception yet reported here.)
* Spur Hill (Tests commenced with streams available since December)
* Woodcock Hill (some "blank carrier" tests, no video streams reported)
* Carin Hill (a report of reception has been made here in Athlone, no frequency information given).

Personally for me, Carin Hill gives me the best chance to receive something though I hope they start some testing from Truskmore soon as I'll be back home in Tyrone very shortly. Might then give the ICDG Wiki a long-needed update when I get the chance.

Hello!

It appears from this document (http://www.bci.ie/DTT/boxer/appendix7.3_coverageplotsmapsA3.pdf) from the BCI, that DTT from Kippure is not due to commence until the 3rd quarter of 2010 unfortunately! I feel a little guilty living where I do (Isle of Mann) as I've been getting DTT since the first MPEG2 tests from Three Rock back in August 2006 and continue to do so - bought a trial box off Ebay before switch to MPEG4 so no prob!

Occasionally there is an interuption of service but it is still a trial / engineering test. I feel guity because so many of you on the forum cannot yet get DTT in Ireland and I do and I'm not even living there not paying a licence to RTE. On the other hand, The Isle of Mann is not part of the UK (and never has been), but I have to pay the BBC in Britain for a service which I cannot get in my location - weird state of affairs or what?! Oh well, the joys and perks of living in the middle of the Irish Sea so close to Ireland!

Good luck to those trying to pick up a signal for Irish DTT! Just had a thought - we could build a repeater here and beam it back along the eastern coast to you, north and south of the border!

Does that not say that DTT from Kippure is due to start Q2 2009 using the existing ATT antenna stacks; and that it will be 2010 before it uses new, recalibrated DTT stacks?

I'm going to withdraw that for now, I suspect it was actually an internet radio station that the particular software, ProgDVB, happened to mix in with the other channels. Of course I'm going to bluff my way out of it by saying if there was a sticky with links to good survey software there wouldn't have been a problem

I checked last night,
I disconnected my temporary Clermont Carn aerial and reconnected my roof-top Cairn Hill Aerial, rescanned and no DTT.

I'm sure I've seen some reports of Greystones intermittendly putting out a signal but I zone in on it. I'm not sure if this is becaue it was off or I'm living even further down a hole than I thought!.

Does anyone know if the Greystones transmission is directional (pointing down to Greystones) or not. As this could be a factor in my not been able to pick it up.

I have not been able to see any DTT signal from Greystones since I started trying just before Christmas. There have been some reports of reception prior to Christmas. Can you see the analogue signals on CH 53, 57 and 63? If you are not receiving those, then you will probably not see the DTT signals when they eventually are switched on.

After my last post, I scanned the Greystones relay before going to bed and lo and behold, CH52 was transmitting Mux1:D I had noticed earlier that TG4 on analogue CH63 was suffering some interference, so the DTT transmissions are presumably to blame.

This morning the four main TV and radio channels are still being transmitted on CH52, with carrier on CH56, 66 and 68. No EPG info, though.

I rescanned here in Greystones last night and picked up 8 stations (signal strenght 90 - 95%). Got the EPG no problem but no picture because the monitor has a freeview tuner.

I have the greystones dtt running on a simple homemade dipole antenna in the living room.

Depends how you interperet the doc. I took that ATT meant Analogue Terestial Television and DTT to mean digital! Who knows??

L1011

ATT is under "antenna"; as is woodcock hill which we know is going to be on in the first stage - I think its entirely safe to assume it refers to the antenna stacks and not the transmission format. ATT does mean "analogue terrestrial television" but in this case its referring to using the existing antenna which were installed for ATT.

The EPG is coming and going on the Greystones relay. It's off again this morning. I have the Three Rock mux and the Greystones mux coming in on my Globalteq receiver and can switch between them easily.

Is this from the same aerial?

Played around with my loft mounted C/D aerial and can get both Three Rock and Greystones at the same time. Located in Wicklow towm BTW.

Increase in power of Spur Hill DTT tests channels noted last Friday.

you might notice new problems with domestic amplifiers etc Rippy!

some TVs now have quite noticeable noise on RTE2 analogue on 57 (which was previously perfect), due to much more powerful DTT test channel on 66 (+9 image issue)

ahh, that might explain why the rf output from my skybox got worse over the weekend.

Sorry to jump in but my question is about signals from Clermont Carn. I have quite a lot of noise on TV 3 which is on 66 from Clermont, would this be from the RTÉ MUX on 57 being strong? (I understand the +9 thing also works in reverse, so any channel +3/-3 or +9/-9 from another CH can cause interference, please correct me if I am wrong). Thanks.

watty

The 9 channel issue is only one direction. +/- 3 is usually OK

your ch66 problem may have bee caused by DTT trials at Greystones if your close to there ch52 ch56 ch 66 and ch68

RTE Mux from Spur Hill in Cork continues on Ch45 (666MHz DTT)

However the 3 other Spur Hill DTT channels that recently were transmitting just 'DTT carriers' on Ch49 (698MHz DTT), Ch66 (834MHz DTT) , Ch68 (850 MHz DTT) appear to be off since a few days ago - good news for South Coast TV/'Deflector' viewers in certain areas whose reception is back to normal - in some instances such signals on adjacent channels were suffering badly! or had "overloaded" mast-head amplifiers (not a problem now),

and also RTE2 analogue Ch57 from Spur Hill is now free of +9 image noise on the TVs that had suffered this problem (which was an issue whilst the powerful DTT test carrier was on Ch66 due to the '+9' issue) as per my post earlier in this thread.
