Mt. Leinster reception

bmaxi

Has Mt. Leinster been broadcasting on reduced power lately? I'd been getting flawless reception on an indoor aerial (please don't start the debate again) but since Christmas it's freezing and pixellating, nothing has changed in the set up and the weather has been much the same.

Why not. Because that is the answer. Google "digital cliff". You are on the edge of it with that thing you don't want us to debate again.

With digital and a poor signal you either get near flawless reception or pixelation or freezing or nothing. TV /Set-box meters are fairly useless as an indication of noise margin.

When the noise margin is small, a small increase in interference or small decrease in signal (due to many weathers not just rain or other reason) results in what you see.

Get an outdoor aerial.

What signal level / quality level does the receiver display compared to when it was working ?

seriously if you are getting intermittant breakup with a digital signal then you have zero margin and time to get a better signal into the receiver

DTT includes a certain amount of error correction code to cater for some signal loss ,

Back to perfect reception this morning, 78% signal 90% quality. It has to have been a glitch somewhere as I didn't make any changes.

I haven't noticed any variation here. I could be the most easterly viewer from Mt. Leinster!

Sorry to be Hijacking the thread but,

Hi Marclt, how reliable is mt Leinster over on the other side? Since around the time of the Olympics last summer, Preseli has been almost flawless around Gorey

I was always curious to see how well it worked in the other direction, also how good was the analogue? (Band III and UHF in comparison)

Also does anyone else even bother receiving the Irish stations over there? thanks,

Hi Aerial Man.

There are reports of reception across the north and west coast of Pembrokeshire. I'm about 15 miles inland on a hill. Tonight I've got Signal strength at 44%, Quality 98% (average). I don't ever seem to get more than about 55% strength but quality is always pretty good. A few drop outs on Sunday night, strength was 30% with no quality. Main difficulty here is the effect of co-channel with a UK transmitter in Swansea. So I have the aerial on the back of the house, only about 3 or so metres above the ground connected to a masthead amp.

Occasionally get a very strong Mullaghanish on CH. 21 in high pressure conditions.

Prior to digital, analogue VHF was better from Kippure, UHF from Mt. Leinster. I've recently moved the aerial to its current position to get a better digital signal.

I was in St. Davids at the weekend, where the relay on the Cathedral outputs on CH. 23 as Mt. Leinster does. I didn't see many aerials pointing to it, although Preseli can be tricky there. A friend who lived in a little village up the coastline from there once told me as a child they only had Irish tv!

Mount Leinster VHF was nulled to the east so wouldn't have been received well on the UK mainland, if at all.

You'd be surprised on that one. Quite a few aerials in some locations for VHF Mt. Leinster. I could get it here, albeit with distortion on the sound. Kippure was better here.

Thanks for the detailed reply.

Would Mullaghanish have good quality during high pressure?

Kippure always was quite reliable on VHF in places where UHF was nonexistent and we always felt that the Horizontal polarization traveled better, especially over the hills etc through Wicklow. Whereas Group A Tv3 (Mt Leinster)was always better than C/d (Kippure) in the same places (Namely North west Wexford, Wicklow )

was it nulled much in comparison to kippure to the east? I found since about ~2009 Rte1 particluarly was what seemed reduced power.
