    Below is the list of frequencies allocated by ComReg for DTT (04Oct2011) - http://www.comreg.ie/radio_spectrum/technical_parameters.542.1071.html.
    ComReg issued two DTT multiplex licences to RTÉ, one in December 2007 the other in May 2011 - http://www.comreg.ie/radio_spectrum/digital_broadcasting.542.517.html.

    I haven't really been paying attention to the Relays (since we use a main Transmitter), but are all on that list on and broadcasting saorview?

    Will the two Clermont Carn MUXs have different ERPs, or is that an error?


  • Registered Users Posts: 9,235 ✭✭✭lucernarian


    That seems odd indeed, Ch53 from Clermont Carn's ERP limit is about 50kW when any previous data suggested that all multiplexes were allocated 160kW. As it stands I thought Clermont Carn was at 40kW for both multiplexes and I can say with certainty that it's not high enough to comprehensively cover its service area.

    It's also the first time I've seen Greenore having an allocation assigned to it. The previous info I've seen in Comreg documents or posted on boards never mentioned Greenore in the RRC-06 allocations.

    I'm not sure if Mount Gabriel is mentioned up there under another place name but it is one that should have spectrum assigned and then used by RTENL for saorview. Also Kilmacthomas, Inishtiogue, Greenore and Drogheda on one of its other allocations (instead of 2 of the PSB muxes from Divis) should have had Saorview transmitters.

    It's also strange to see that Fanad has a lower ERP than Malin. Fanad's site is further away from NI and has historically served a larger area than Malin.

    Greenore's planned 200W allocation was under the 250W cutoff for RRC-06 planning so wouldn't have appeared in any documents from that time.
    I'm not sure if Mount Gabriel is mentioned up there under another place name but it is one that should have spectrum assigned and then used by RTENL for saorview.

    Mt Gabriel doesn't have a DTT allocation, the nearest appears to be Bantry.

    I'm well aware of that particular aspect.

    But e.g. Drogheda's allocation in the document in this thread is under the threshold for the RRC negotiations yet it was included in RRC06. The likely conclusion when this and other relays on the border in NI were previously discussed was that they were negotiated on the basis of an ERP of "250W". Mainly so that they could be coordinated as part of RRC06. In reality some of the relays will not have a power close to that even if technically the 24dBW allocation remains. E.g. Benagh, Gortnalee.

    What suprises me is that the same trick was not applied with Greenore so that it could also have spectrum allocated under RRC06. If a relay with planned ERP of 21dBw 30km from the border was dragged into RRC06 then surely a relay 5km from the border would have been given the same treatment, like OfCom did with NI's relays?

    Perhaps Greenore was simply an oversight on the Dept's part during RRC06 and with the congested spectrum in the area, there's simply no space for two Group B multiplexes until after ASO, thereby ruling it out.

    Mount Gabriel UHF analogue TV broadcasts at 1kW EIRP if I remember correctly yet it never received an allocation... That's quite peculiar.

    I don't think it matters whether Greenore was included in RRC-06 or not, it was still included in RTÉ's and Comreg's plans for DTT as we can see from the Comreg document.

    Greenore, Mount Gabriel and all the other approx 120 analogue sites appear to have been cut from the plans due to financial reasons when the DTT plan was was revised to 51 sites early last year following the failure of the commercial DTT process, to replaced by Saorsat coverage.

    Had a look at the Louth Co Co planning website, couldn't find an application for a transmitter covering Greenore. As the allocation still exists in the Comreg documents maybe it'll come in future depending on the success of Saorsat.


  • Registered Users Posts: 9,235 ✭✭✭lucernarian


    Then you'd have to ask why Drogheda was included in RRC06 if its impact across the border is even less than that of the Greenore relay. It was also cut from the plans, though after the Saorview rollout had started.

    It seems the plans for DTT from Drogheda were more advanced than Greenore having been included in RRC-06, Comreg 2007 list of sites and the original 53 site plan.

    Why was it included and then dropped, Comreg and RTÉNL are the people to ask I guess.


  • Registered Users Posts: 9,235 ✭✭✭lucernarian


    And that's the thing, the Greenore relay seemed like an afterthought after RRC06 already happened. It's clear some kind of coordination would be necessary for Greenore even if under the 250W limit. And the absence of a high-powered relay like Mt. Gabriel from any Saorview plans seems like a real oversight on ComReg's part.

    Saorsat shouldn't be regarded as a panacea for coverage when it will require the purchase, install and use of specific equipment for it at a much higher cost than for the Saorview service in most cases. I guess it depends on the exact cost of providing Saorview coverage from existing sites but if Laragh, Co. Wicklow can justify it then so can Mt. Gabriel. And I do believe these allocations would have been decided on before any decision was taken on Saorsat.

    I'd guess its an error. MUX 1 and 2 strengths from the other Tx's seem to be the same. Is it not still the case that CC will go to 160 Kw and omnidirectional after ASO?

    Error in line 4 of the spreadsheet. The frequency of Lyric FM from CC is listed as 87.8 Mhz. Line 126 says RTE Radio 1's frequency is 95.2 MHz. Should be the other way round.

    No more an afterthought than any of the 188 planned RTÉNL PSB sites not included in the 43 at RRC-06 at the time.

    My guess is the Greenore DTT site was a replacement/renaming of the exiting Carlingford analogue site, same aerial group and same max ERP.
    And the absence of a high-powered relay like Mt. Gabriel from any Saorview plans seems like a real oversight on ComReg's part.

    Probably a cost saving measure on RTÉ's part. Comreg said in 2007 of Mt Gabriel, Carlingford and other analogue sites at the time
    The following are sites currently in use by analogue television transmission operators and may be considered suitable for use as part of a DVB-T network. Suitable frequency assignments can be found, if a DVB-T multiplex operator so requires.


  • Registered Users Posts: 9,235 ✭✭✭lucernarian


    But Mt. Gabriel compared to Laragh, serving a lightly populated valley in Wicklow at 20W ERP? Doesn't really add up. That's up to RTE to answer I suppose.

    And hold on a moment, the large majority of those 180-odd PSB sites were not 3km from the NI border and less than 10km from a relay which was allocated 8 channels from the same aerial group in NI! Coordination would be necessary even if not under the auspices of RRC06.

    Your guess is likely correct in that the Carlingford relay is actually located in Greenore but is built to serve Carlingford and Carlingford is by far the larger town and more recognisable. I.e. they are talking about the one and the same site. Ch. 47 happens to be the unused allocation for TV3 from Greenore.

    The cost saving is put down to "RTÉ's part" but two points must be considered there. Firstly DCENR pays RTENL's operating costs to a substantial degree and building more DTT sites is not going to come from nothing. Secondly, the DCENR helped fashion the Broadcasting Act 2009 which stipulated rather weak population coverage targets. I.e. no motivation to improve terrestrial coverage beyond the avoidance of political controversy at ASO and to ensure that advertising was still broadcast to a similar number of people as currently happens.

    As we discussed in another thread (re: Ch 39 Mt Leinster) bi-lateral coordination on DTT frequencies has been happening since the late 90's incl post RRC-06 as has been stated by both the Dept and Comreg. The border region is no different.

    RTÉ/RTÉNL operates on a budget of the Licence Fee and advertising and no additional cash has been allocated by the government to pay for the network upgrade. They are borrowing the money to pay for it.

    Exactly. Who pays the license fee to RTÉ? Who guarantees the €70 million they got from some bank in the UK, I forget which?

    You said that the absence of Carlingford from RRC06 is no more an oversight than any other of the numerous smaller sites around Ireland. Do you say this because there were continuous background negotiations over the remaining sites? It seems strange that an allocation has emerged only this year, and no mention of what the 2nd Mux would be assigned to. And this is the outcome from the same group of people who thought it would be fine to have a PSB multiplex broadcast on the same channel as another high-power mux only 150km or so. I wouldn't describe the spectrum planning aspects of ComReg as having the most foresight and attention to detail.

    My guess would be that the PSB 1 mux allocations were given in 2007/08 when the commercial DTT plan was still in play and costs would be shared but as that process dragged on and the commercial muxes looked less likely and with RTÉ having to shoulder all the costs of the upgrade, the plan had to be revised down to 51 sites, removing 9 of the Mux 1 sites already planned and halting any further planning for new sites in early 2010.

    Regarding Mux 2, these were only licenced by Comreg in May this year. That's about a year after the revised 51 site plan was submitted to the Dept for approval, so no Mux 2 frequency was allocated to sites not already in the 51 site plan.

    Regarding the allocations only emerging this year that's not surprising considering outside the original 12/13 main sites, for which we know the first 4 multiplex allocations, we only found out in Feb the Mux 1 frequencies for all 51 sites and then not directly from RTÉNL but from Watty who posted them following an RTÉNL Saorview presentation to the ISAA. We wouldn't know about the 9 other sites only Comreg published them on their site, maybe allocations exist for other sites also but will never be published.

    In recent Comreg published documents regarding the liberalisation of the mobile bands and release of the upper TV band, UHF Chs 60-69, for mobile services Comreg has indicated that UHF Ch 60 will not be used for DTT in the current 6 multiplex plan.

    The plan is to use UHF Chs 21-59 only.

    This would give a 9 MHz guard band between DTT and mobile services thus reducing the possibilty of interference to TV services.

    Future 7th and 8th multiplexes are also planned for UHF Chs 21-59 but could use UHF Ch 60 if required.
    ComReg does not require the use of Channel 60 for the provision of the first six DTT multiplexes in Ireland. In addition, ComReg is planning the 7th and 8th DTT multiplexes on the basis that they would mainly or only use Channels 21-59.

    Don't forget they still have options on VHF. Unlikely, but within the Saorview spec.

    I think it's unlikely too considering that they're planning up to 8 muxes in the UHF band but VHF hasn't been ruled out according to RTÉNL earlier this year.

    Comreg said in 2008 "It is intended that Band III will not be used as part of Irelands National DTT service, which is due to launch late 2009".

    There's not much point in leaving it completely idle and DAB will never fully occupy it I suspect.

    DAB shouldn't be on it at all. Only DVB-T2 Lite, DAB+ or DRM+ for radio (DVB-T2 Lite and DRM+ can use the same 1.7MHz channel as DAB).

    DAB is obsolete. It was launched too early.

    Also Radio is not like Multichannel Satellite TV. It's not 100% convincing that we need any of the 6 or so competing Digital Radio systems.

    At 270MHz and MOBILE Digital you also need a huge amount more transmitters for coverage as reliable as FM on Band II.

    RTE did Limerick and one corner of the Country about 5 years ago when Plain DAB was already clearly a failure. Why? Notably they have not added to it.

    It's quite a good band for Two-way radio fleets.

    Whether it's called Eureka 147 or DAB/+ isn't what I was concerned about, I don't think digital radio would ever occupy all of band III.

    RTÉNL has uploaded the official list of Saorview Mux 1 frequencies, sites and their max ERPs to their website.

    http://www.rtenl.ie/wp-content/uploads/2011/12/SAORVIEW-Frequencies-Rev-1.0.pdf


  • Registered Users Posts: 15,452 ✭✭✭✭The Cush


    Rev. 2 of the list of Saorview Frequencies is now up. It includes the planned frequency change at Three-Rock on July 10th and the new planned sites but without their frequencies or ERPs.


  • Registered Users Posts: 15,452 ✭✭✭✭The Cush


    Rev 2.1/2.2 of the list of Saorview Frequencies now up on the RTÉNL website.

    New transmitter sites added but without their frequencies or ERPs. Also the document indicates the frequency changes and increase in ERPs will now happen after ASO, the previous revision indicated these changes would happen at ASO.

    Comreg's newest technical parameters document includes information for the 4 relays announced in March

    I'm sure The Cush will put it into his fancy table but here's the basic information

    Bandon
    PSB 01 - 47V - 50W
    PSB 02 - 44V - 50W

    Dingle
    PSB 01 - 30V - 500W
    PSB 02 - 26V - 500W

    Glenties
    PSB 01 - 46V - 100W
    PSB 02 - 50V - 100W

    Greenore
    PSB 01 - 43V - 200W
    PSB 02 - 40V - 200W

    Glenties and Bandon are reported as V pol, but Saorview coverage checeker and RTE's analog list list both as H pol.

    Someone in RTENL must also have realised that the analogue powers were way too low:

    Bandon goes from an 8W analog site to a 50W digital site.
    Dingle goes from a 100W analog site to a 500W digital site.
    Glenties power stays the same.
    Greenore goes from 60W analog to 200W digital.

    No point updating the fancy table in post #1 as the information will appear in the RTÉNL list of Saorview frequencies in due course. I posted that table a few months before RTÉNL published its first official list of Saorview frequencies.

    Some of the information on the 4 sites such as frequency and pol. appeared in Rev. 2 of the RTÉNL list from last Jun.

    Another point of interest, in the document above, the power for Three Rock has been upgraded to 125kW. Are RTE now using that power as opposed to the previously used 63kW on C54?

    The latest Saorview list of frequencies continues to show the ERP for Ch.30 at 63kW.

    Any possible future conflicts with Brougher Mt NImux Ch.30 and/or the Belfast Local Mux Ch.30?

    Just a query that someone might help me on, it may be somewhere else on the Boards.

    I'm not great on TV technology but can anyone advise if there are plans
    or proposals to have the UK freeview channels also available on Saorview?

    Is this something that will eventually happen?
