It should be on full power if not right now then later today. It's certainly coming in stronger than the old Multiplex 1 though not by a huge margin.

Multiplexs A, C & D on E23, E29 and E33 are also back on at Brougher as are the remaining three analogue channels.

That's strange, the plan was to move Mux C from E48 to E29.

I blame Doris

Must dig out my old humax pvr and check, was able to get it pre dso power in roscommon but very weather dependent.

Noticed an interesting observation trying to get the new BBC A mux from Brougher with an indoor aerial - because the "direct" signal has to come through a number of walls, there's not much success directly pointing the aerial that direction. However pointing the aerial through a window at a mountain in the near distance, facing almost 180 degrees away from Brougher Mountain is giving a good signal.

All services now back up at Brougher. I'm away to bed now for a few hours :pac:

I need to get this. I live in direct line of site of Kilkeel transmitter. Im in Clogherhead. There is an aerial up in the loft, but its not really pointing at anything. In fact, its not a point kind of aerial at all. There is a signal booster etc, but when I tune in, all I get is a really bad reception on TV3 and RTE. I get some music channel too, which is equally bad.

My TV on autotune tells me these channels are found under the heading "TV", it finds no channels on the "DTV" part. Any ideas?

CRM Ireland · 10-10-2012 4:10am

Ive just went up into the loft, which is quite the frightening experience at this time of night with all the spiders lurking up there..freezing too!

Here is the aerial. Im not sure which way is the front, upside down or anything. I actually managed to manually find the satellite for UK Freesat a couple of months ago, so you would think this would be a lot easier. Anyone know which way to rotate this?

Is this even good enough to pick up freeview? I would have thought so, but you never know!

Relays won't start broadcasting Freeview until later in the day.

Good Morning Ulster on BBC radio Ulster is being inundated with calls asking why ALL analogue channels are off.

sesswhat · 10-10-2012 7:46am

As a crude test, Limavady BBC has improved from a patchy 20% signal strength to an error-free 93% on the TVs own meter at my location south of Ballybofey.

formerly scottish paddy · 10-10-2012 8:13am

That seems good for 20kw!

sesswhat · 10-10-2012 8:22am

Digital TV service from Strabane for the first time on CH45. BBC digital now available for many parts of East Donegal and Derry/Tyrone west of the Sperrins.

Delboy5 · 10-10-2012 8:25am

On the Monaghan\Fermanagh border getting Freeview from Divis.
Last night i checked my STB's inbuilt signal meter, strength was showing as approx 30 and quality about 90.

This morning after a rescan im getting strength 72 and quality 100 !

This should be a good indication of getting all the rest on the 24th !

Yes, but remember COM muxes down a good bit on 100kw PSB Muxes (if you like shopping channels?

)

The COM muxes are only down by 3dB - it's not that much.

But how strong is the BBCA mux from Brougher? This will give an indication of the possible co-channel interference between Divis PSB muxes and Brougher COM muxes at this location.

The most important reading in that screenshot is the C/N: a whopping 27.4dB. That is a result! What kind of aerial are you using? Divis is romping into the Republic...

If you hit the refresh key you will see the latest state of play with the relays across all three transmitter groups. Kilkeel will be live this afternoon and I see Strabane is already operational. The more reception reports the better!

Im not 100% certain, as it was installed 5/6 years ago but i think it was a Triax Unix 100 Group A !?

A high-gain system. Nice screenshot BTW.

adox · 10-10-2012 9:57am

if there is anyone in North Dublin tuning in to the Kilkeel transmitter this afternoon, can you report on here?

I will be having a go when I get home from work tonight but would love some feedback from others who have tried already.

Thanks.

From looking at my signal readings, does that mean i should get the exact same strength and quality readings on the other Public Muxes on the 24th ?

Does is also mean that i will get the COM Muxes at half the strength and quality of the Public Muxes, 50Kw as opposed to 100Kw !?

It's not that simple. It was asked already by reslfj, but are you getting anything from Brougher on ch. 28?

The C/N will be 3dB down, (half of 100kW = 50kW), so around 24.0dB provided there is no CCI from Brougher. With a high-gain directional aerial this should be minimised. The 24th will be revealing.

Unfortunately at work now so cant check till this evening, if tonight i do a Manual scan on Channel28 and it picks up something what will that mean.......?

It won't mean anything as regards the Divis com. muxes, but the Brougher coms. could cause problems for the Divis PSBs. Hopefully unlikely though.

Kilkeel now coming in fine here to Balbriggan.
Checked with both an attic-mounted wideband aerial with mast head amp, and an old roof-mounted contract aerial with lossy cable. Not much above sea level in a relatively built up area.

It isn't Kilkeel. It is not on air yet according to Digital UK. Check the UHF channel number: if its E27 you are getting Divis which is more likely.
