DTT Tests @ Clermont Carn

Rick_ · 2009-04-01 09:53:30

A place for us to discuss the tests from Clermont... and basically because the other transmitters are getting their own seperate threads, so why not Clermont? :p Anyones signal get better over the last day or two? Mine went from very low and poppy/clicky to quite stable since yesterday... Atmospherics or a power increase?

I noticed the drop in strength a couple of weeks back and it stayed under 70% since but when I checked 31 March it was back to around 95. Noticed the test card on TG4 31 March and now the lot is gone, great timing for the match!

Is the "North shielding" on Claremont supposed to be temporary (Im guessing from the Boxer coverage maps the answer is yes). If so which transmitters/relays is it supposed to be protecting and why is it also being applied to the DAB services ?

Judging by maps provided in some official documents on receiption strangth I remember seeing from a link on here a while ago, reception in NI will be quite possible in many places but it still said that the signal will be restricted northwards. I guess they just can't help overspill really as the signal cannot be 'killed' as soon as it hits the border and there are people on the northern side of the transmitter who will have to be able to receive the service too, so I'd say it's just on low power rather than completely nulled altogether.

Any idea when this testing will stop, as nobody in our area can get any TV reception at all at the moment? We're still in the dark ages I'm afriad with neither cable of satelite TV.

Yes, it's on. No apparent interruptions since the 2nd. However I have only been checking in the evenings. Not sure about daytime.

According to this document, up to the end of Q4, 2012, DTT transmissions from CC are set at 50 Kw due to NI restrictions. However from Q1, 2013, ERP rises to 160 Kw, with no NI restrictions indicated. Could this also indicate an end to nulling of CC DTT transmissions to the North?

That's something similar to what I saw but the PDF I looked at had coverage maps on it where some of NI was included but by 2012/2013 practically all of it was covered by the various ROI transmitters. So it would seem that after DSO there won't be any restrictions at all and many NI viewers can receive the ROI DTT service too and vice versa given the power increases...

Here's hoping that will be the case. Maybe then we'll be able to ditch the uber expensive Sky option to view RTÉ in proper digital 16:9. I'm assuming that the current restrictions are due to possible interference on analogue services north of the border from Irish DTT. After all analogue services are shut down up here, there should no further need to restrict output. Unless of course there's a risk of interference to northern DTT services as well! If that's the case, it'll be keep on paying I suppose.

Well, the DTT signals will be on 53, 57 and 60 at least, with the DTT signals from the northern transmitters mainly the same as their analogue counterparts, which seem to be in the 40's and 50's, and as there doesn't appear to me any / much interference at the moment, I wouldn't imagine there would be any problems. Then again we won't know until then!

Remember all frequencies are agreed internationally to avoid interference. After ASO there should be no problems between transmitters in Ireland N&S.

Just tried tuning in the dtt from clermont on my new panasonic freesat/freeview tele and it gets a fairly weak but with very few break ups signal here in the country side between hillsborough and dromore co down .

I have a mast head pre amp on my c/d aerial.

The channels come up as encrypted (?) but clear OK but there there is no epg showing.

Regards,

Sky

One of my TV's was quite stubborn and wouldn't even acknowledge a signal on CH53 whilst others would, but I noticed today that it gave a good signal and tuned the 8 channels in fine. I was thinking it might have been a power increase (but it's probably just atmospherics) but I have a DVD recorder with built in DTT and it now refuses to even slow down the search when it comes to CH53 (unfortunatly, you cannot manually tune in one MUX and a full scan must be done every time).

I am picking up on a viera tv - RnaG on channel 8 - Radio Service - CH53 730Mhz on freeview (based in South Derry).

Its a poor signal - says encrypted and there is an epg showing.

I am not picking this up on my other freeview goodmans box.

Are you sure you're getting it from Clermont? South Derry seems a bit far for reception... but then again, stranger things have happened!

Yip. Thats Irish DTT alright. although its flagged as encrypted, its not.

You would be picking up the TV channels as well, except there is an issue with the panasonics at present. You say a Viera - a PZ81 or LZD81 ?

sorry for the delay in getting back to you - its a Veira 32 LMD70.

the signal is still showing bad signal, but i am getting sound (Britney is on at the minute tbh) - probably because of the good weather.

did another scan - no other channels have appeared.

TG4 seems to take a while to appear. Sound is there immediately. But the picture can take 5 to 10 seconds to appear. Been happening the last week or so. Other 3 TV stations are ok.

Signal seems to be gone again from Clermont, or at least it's not receivable in Armagh. Loverly weather usually gives me a little boost in reception but all day I can't receive anything on CH53. Is this the same for everyone else or might it be a case of RTÉ testing their restriction patterns for northerners again?

So it could be low power again then?

When operating at the power levels they have been over the past few weeks I can receive the service fine, so if it returns to that or anything higher I should be OK then for any future reception when it fully launches, providing they don't modify their northern restrictions any more!

If you're in the Derry/Donegal area you wouldn't be receiving from Clermont though. I can't get anything on Clermont at the moment...
