Freeview Retune Sept 30th - Changes at Divis?

Mayo Exile

This is happening on Wednesday isn't it? Just wondering what will be the changes at Divis? Are all the BBC services (BBC4, CBeebies etc.) being taken off Mux B (UHF ch. 26) and being put on either Mux 1 (ch 29) or Mux A (ch 23)?

Bummer if so, as ch 26 is the best reception for me here in Dundalk. Chs 29 and 23 quite poor.

For Divis the changes are:

· FIVE and ITV 4 are swapping MUX's [to help increase FIVE's coverage]
· ITV 2+1 and ITV 3 are swapping MUX's

This is rather annoying as the ITV/C4 MUX is on very low power and is prone to break-up a lot of the time so essentially I think there will be a good percentage of NI Freeviewers who willend up losing FIVE but will gain ITV 4 from it. Same goes for ITV 3/ITV 2+1, at least having 2+1 was handy as it meant ITV 2 was still receivable in some form, now were losing it in favour of a golden oldies channel mostly.

The big Freeview re-order whereby MUX B gets vacated by all services and is filled with 4 HD services is currently only happening at a few locations in England where Freeview HD is launching. NI won't be getting HD on Freeview until DSO in 2012/2013 at which point all transmitters will be broadcasting it including relays, so those close to the border should be able to pick it up from certain relay transmitters and not have to rely on the 3 main ones (unless they want all the channels and not just the PSB's plus HD).

Mayo Exile

Cheers Paddy C. So FIVE goes on to Mux 2 on ch 33? Is Divis going up to 75 KW ERP in 2013 after DSO? This should improve reception, plus extend spillover into RoI I'd guess.

lucernarian

If Five are being moved to a weaker multiplex, how then would it increase Five's coverage??

Rick_

I think it means to increase it's coverage post-DSO as the relays will not be broadcasting all 6 MUX's, only the 3 PSB's, which FIVE are currently not on. Instead of moving them to a PSB MUX region by region as they switch, it's being done now for everyone to save time. If you currently receive all the Freeview channels, don't worry you won't lose anything, you will just have to retune to make sure you still receive everything after the services do a bit of musical chairs.

After DSO, Divis will be increasing from the poxy 2k it has now to 75k, so it will stabalise everyones reception in NI and will, I'm sure, give some ROI viewers some nice new free channels to watch as well.

CORRECTION : DIVIS is 100 kW after DSO. Do not believe what you read on the enthusiasts ukfree.tv. The official ERP is 1/5th of analogue ERP for PSB muxes: see Ofcom, DUK and the international allocations. Divis, like Caldbeck its analogue peer, is 1/5th of analogue ERPs in the DSO era.

Rick_

Well, there you go, an extra 25kW of power to push the signal a little bit further over the border!

Both MUX2 and MUXA/SDN operates at the same power level (2.3kW) and both mux signals should have same robustness from Divis.
ITV2+1 is on MUX-D which operates at half the power (1.6kW) but with the more robust 16-QAM mode.

From Divis ITV2+1 will be a little less robust and ITV3 a little more robust.

I will add that some of the muxes may have directional antennas, which may change the general picture described above for some viewers.

These 'few' are all post-DSO locations i.e. Devon, Cornwall, Presely, Carmel and Kilvey Hill in Wales, Selkirk, Caldbeck and IOM (and all their relays). Llanddona and Moul y Parc (and Long Mountain) in Wales will not use the PSB-3 channels from DSO phase 2 (November) and until (sometime) after DSO phase 2 Granada (Dec 2.)

PSB 1-3 ch21, 24, 27 from 2.3kW, 2.3kW, 2.3kW  to 100kW = +16.4dB
COM 4-6 ch23, 26, 29 from 2.3kW, 2.0kW, 1.6kW  to  50kW = +13.4dB(MUX-A/COM-4) 

The 75kW is the average ERP, but you cannot receive 'an average signal' - you need the strength of each signal.

Its likely that the COM muxes will be interfered with by Three Rock DTT which will be cochannel, particularly in East and South Down (exactly as today where the relationship is between low-power Divis DTT and Three Rock.) The PSB Divis channels will be clear: these are the most important ones. This is the same as the current new situation between Preseli DSO and Mount Leinster where Preseli PSB muxes are clear and Preseli COM muxes are cochannel with Mount Leinster, should that be fully rolled out!.

Why does multiplex with ITV4 (Mux A) suffer more breakup than that with Five (Mux 2) at present when both are at same erp? At least that is how it is with my setup - I use a wideband aerial to pick up all DTT channels from Divis (including Mux C on Ch.48) and is it because Mux A has higher channel No. (33) and wideband aerials cope better with those in lower channel band (Mux 2 is 23)? Or is this pure speculation on my part? Am I right in suggesting as another post does above that for me and some others Five may now be more prone to breakup after tomorrow's retune?

tvman

After the retune looks like I will loose five via my STB. I lost all the ITV channels when RTE started DTT tests or at least it seems that way - they disappeared around the same time and they were never great anyway always prone to break up.
I had five via the STB fed into my analogue distribution system, will still have it via freesat etc. will have to fire up one of my old satellite receivers with a rf output to keep five in the analogue setup.
I will report back what the retune results are at my location (SW of Dundalk)

lucernarian

Post DSO Divis will not be affected by Three Rock DTT. The internationally approved allocations to Three Rock/Kippure are 54 58 61 and 64.

What will surely bollox it up for people living in Drogheda and generally further south is the relay that's planned to be installed on top of the Lourdes Hospital. On Chs 21 24 27 31. This is, interestingly enough, in a town where about 40% of houses have an aerial especially for Divis, with a chunk of that being able to get some of the freeview channels normally.

ERP of 130W but that will surely overpower the distant Divis signal in several areas.

Kippure and Three Rock actually have 8 DTT multiplexes allocated in the GE-O6 pan including Group A channels.

See :

Of course whether these will ever be used is another matter and I fully agree the Drogheda relay should be rechannelled. The interference from high power Divis will be considerable given some of the CCI issues already seen in the UK with high power DTT.

Yes, that is correct. After lunchtime today FIVE will be (in my house at least) unwatchable via Freeview from now on and instead I get rock solid ITV 4 to replace it. ITV 2 +1 will also go in favour of a rock solid ITV 3. So, essentially I'm losing 2 channels that would get watched often enough for 2 channels that don't get watched at all. :mad:

So that's UTV, Channel 4, FIVE, E4, More 4, Channel 4 +1, ITV 2 and ITV 2+1 that I won't have access to. Great. :rolleyes:

Mayo Exile

Have the changes occurred yet? In work at the moment so can't check.

Rick_

Well the retune has happened, I have now lost UTV, Channel 4, FIVE, Channel 4 +1, E4, More 4, ITV 2 and ITV 2+1, all so I could gain ITV 3 and ITV 4 which I don't even watch! I wouldn't mind if the signal was a bit stronger so I could actually receive the missing channels as well, but losing FIVE and continual loss of all those other channels just so I could watch ITV 3 and ITV 4 is a disgrace. I can't wait for the DSO now. Pity it's bloody 3 years away at least. :mad:

Mayo Exile

Thanks Paddy C. Have all the BBC services gone from channel 26 (Mux as well?

Rick_

No, the services will not clear from MUX B until DSO for Divis. They were only clearing out today in areas already switched over and also part of the HD trial/service which starts in December.

No transmitters in NI are part of this service, we are being left out as usual and won't get anything until years after everyone else.

This was always going to happen. A nationwide reorganisation was necessary in the UK for Freeview HD. The current Divis DTT service is pants because they never asked for sufficient powers at the start and a new mast has to be built. Annoyingly those in SE Ireland will get the Freeview HD service soon with the right boxes and as Jordy Lyons (a well known installer, ex IBA) noted over on ukfree.tv, there are parts of East and South Down can NOW get Winter Hill: and this before the ERP goes up by a factor of 10 in November. In addition Caldbeck and Cambret will also be switched to Freeview HD before next summer, so the overspill areas will have Freeview HD in time for the World Cup. Norn Iron is indeed last...

skycatcher

I'm going to have to do a re-scan (factory reset) on my panny so there goes my RTENL services again!- only a month or so after getting themback!:mad:

Rick_

If they could just bump the power up by a few kWs it would make a world of difference stability wise for a lot of people, most of the MUX's aren't even running at decent levels now, I mean, considering that they are pushing for everyone in NI to move to Freeview in the next few years, what harm will it really do by increasing the power a wee bit and giving those who have already converted, or those that are looking to but can't because of the crap signal a wee bit of a head start?

Thanks, Paddy C. Didn't know this. Thought they were clearing out Mux B everywhere at once.

Very interesting. Would coastal areas of Meath & Louth also pick up Winter Hill transmissions when this power increase occurs in November? I could be wrong, but I think it's been mentioned in this forum before that Caldbeck has been picked up in parts of Louth when atmospheric conditions were suitable.

Yes, I would think so. Winter Hill is going from 10kW to 100kW in November and its omnidirectional (this is the reason why all the North Wales stations are all being DSO'd at the same time and changing channels, particularly at Llandona). WH will definitely cover the Southern Isle of Man and DUK reports availability in parts of East Down. The higher up you are with a sea view the better. Caldbeck is receivable in lift conditions in Louth and Caradon Hill is apparently now being received in SE Ireland near Tramore and Kilnsale. There's been quite a lot of discussion of this over on ukfree.tv. Naturally you'll need a high performance aerial. This happens from Nlovember 4th and it'll be the first Freeview HD station from December although boxes will be like gold dust..

lucernarian

I've managed to pick up sound and fuzzy black and white TV from Winter Hill on Ch. 65 (Channel 4) with a contract C/D aerial 6 ft off the ground at my house. Only a low hill blocks sea view in that direction. Still, I don't think the power boost will be enough.

Needs a rooftop antenna: the ambitious DTT-Dxer will be going for a masthead/high gain wideband antenna and rotor!

DTT behaves differently from analogue as people are now finding out with the high power DTT signals appearing.

Five of the six multiplexes currently being broadcast at Divis are co-channel with DTT multiplexes on Brougher Mountain. If both transmitter sites keep their ERP's fairly low up to a level which (a) does not cause interruption to current analogue services and (b) interruption to each others' service, interference between the two can be kept to a minimum. If one or the other were to notably increase the ERP of their multiplexes, it would affect the reception of those receiving from the other transmitter on some places, especially those with fringe reception. It would just seem that the ERPs of current multiplexes being broadcast are about the level before "tipping over".

Muxs 2 & A from Divis AIUI broadcast with the same ERP and both from the current analogue aerial should in theory should be received approx. equally well at the reception site, however the propagation of the signal at the transmission site and characteristics at certain reception points along with its equipment e.g. properties of the reception aerial, can give differing results and may leave heads scratching. Mux 2 is on E33, which is the highest frequency being broadcast from the analogue aerial - it may be the case that the propagation from the transmitting aerial might not have had such a frequency designed (even allowing the aerial grouping) in mind and therefore gives some quirk's compared to other services, meaning that in some places it appears weaker and in others stronger compared to the other services in the same aerial group. This is often down to the radiation pattern which looks more like a petal shape than truly circular. For analogue TV, this quirks could be seen on Brougher Mountain where Channel 4 appeared to come in a little weaker compared to BBC1, BBC2 and UTV but some work at the site a few years ago seems to have levelled this. Ditto for Carin Hill, where in fringe areas TG4 appears to come in weaker than the other three services. The main link appears to be the highest the highest frequency transmitted within an aerial group. Screening in theory could also be considered but is unlikely.

This isn't going to happen till DSO. Current Divis DTT services are cochannel with some Caldbeck channels. The current kit is from 1998, a new mast is to be built (it does now have planning permission btw), and the new system will be installed in 2012/2013. There's no point in Arqiva spending money on interim fixes when a very high performance new system will be put in the next three years, including HD. No investment case and Arqiva are very commercial. As everywhere else in the UK the existing low powered DTT infrastructure is being binned.

I agree. If there was an opportunity to increase ERP's it would have been done earlier this decade (I think E48 from Divis had a power increase, but that was it.)

Yes, but as I understand E34 is definitely and I also believe E48 as well are transmitted from a separate aerial slightly lower down the current mast.

I've been reading this forum with some interest.

It's actually the opposite way round... Muxes C & D are broadcast from the two by two panels plonked on top of the analogue stack. The other muxes are broadcast from the 2 by 4 tiered panels bolted above the vhf crossbow array. It's do with some old Crown Castle commercial way of thinking.

This is absolutely correct - Divis psb's are 100kw erp after and the com's will be putting down 50... It does however cause problems for Brougher which effectively becomes an SFN with Divis. It's com channels will be restricted to 2kw. A part of the GE-06 spectrum plan was to include co-channeling three rock. It has caused some discussion about it's effects on parts of Omagh which rx from Brougher. It may be likely in the coming years before we switch that some of the triggers are revised as Digital UK have said themselves the plan for Northern Ireland is not fully locked down.

SFN, rx, "triggers"

Here i thought was a forum of learned people ffs...

An SFN is a Single frequency network, where two or more transmitter's use the same frequencies for example Budleigh Salterton and Beacon hill. Brougher and Divis will use the same frequencies as will three rock dtt...

Rx stands for receive just as tx stands for transmit.

Triggers refer to the international allocation of spectrum and govern the put down (db) of a transmitter in a foreign country...

lucernarian

Are Brougher and Divis not too far apart to allow an SFN unless the guard interval was changed to something horrific like 1/4??

The case for SFN is obvious with Three Rock and Kippure, but I think Brougher and Divis allocations are just a "hope for the best" idea. More resillient signals will mean that a directional aerial will pick up a more noisy signal that a receiver will still pick up.

Remember, even if the competing signal is stronger, all that matters is the difference in strength between the two. If both tx's muxes have better SNR values, then that difference in strength can be lowered without negative impact.

They're definitely not to far away from each other... Remember Brougher was an analogue rbl of Divis for years before moving to hard line fibre. With analogue 1/5 of dtt, there's going to be serious overlapping were none existed before.

You're absolutely right in what you say it would be horrific to move to 1/4 in 8k mode. They would need to look at changing the cyclic prefix and even then it be something ridiculous. I don't think for a second there will ever be an SFN between the two but the co-channeling and the amount of wideband aerials out there is going to cause retuning havoc. Northern Ireland is as you say is hit and hope and everytime i speak with someone from DUK it's the same answer. "The plan for Northern Ireland hasn't been locked down yet".
They still haven't sorted out channel 30 and went ahead and launched the scottish psb mux from Caldbeck. There will have to be mux re-organisation within the next year to sort negative channel offsets as Scotland begins it's switch...

With respect.. What is it you don't understand...

SRB

Slightly off topic, but what has happened to the planned SFN for Three Rock and Kippure ? Apart from a few "attempts" around Easter, the muxes have settled on 54 and 61.
