Craigavon Colin, what are the levels on the other channels?JKWednesday 24 October 2012 7:06PM
Craigavon In case this is helpful to someone else trying to get the NIMM. My earlier post details signal levels but 35% on C39 and 80% all others.
I use a variable signal booster to feed a loftbox and 4 other rooms. If I adjust the booster down to a point where signal level is 60% on main channels ( and all work well ), the RTE mux disappears.
JK: The main Freeview channels come from Divis whereas the NIMM is from the adjacent Black Mountain. At your location they are only 2 degrees apart which is probably nothing as far as sensitivity of the aerial is concerned.
However, it is always possible that there is something that is reducing the level of the signal from Black Hill. For example, a building or tree.
With this in mind, try moving your aerial around the loft and see if reception of the NIMM improves. I suggest that you connect your TV directly to the aerial (perhaps via the variable booster but not via the Loftbox). This will rule out the possibility of the Loftbox causing the issue.

Craigavon Thanks Dave. Will check it out at the weekend. AerialmanWednesday 24 October 2012 8:47PM
The final destination for SV2 at Clermont Carn is channel 56,is it not?
Which would be quite logical. PeteLadWednesday 24 October 2012 9:53PM
I'm in Lisburn BT28, and receiving Clermont Carn on ch52 (RTE1/RTE2HD/3e/etc) via an amplified indoor aerial (similar to 
http://www.amazon.co.uk/d…E0), set horizontal and pointed towards Divis! Picking up all muxes via both Divis and Clermont Carn no issues.
Was waiting for the digital switch over to get an aerial installed, but going to just go with the indoor one I've managed to hide away.
I suspect that aerial men may well see a lower volume of work long term with the performance I'm seeing off an indoor aerial! JKWednesday 24 October 2012 10:31PM
Craigavon Petelad thanks for that info. I immediately went to find an old indoor aerial ( no amp ) and plugged it in to my TV. Got all the rte channels inc TV3 from CCarn on C52.
Although this does raise another question. This LG TV doesn't pick up the HD channels or the NIMM from Divis so I assume its not Mpeg4 compatible. Not sure whats going on!
Still, I can't complain.PeteLadWednesday 24 October 2012 11:59PM
Jk my LG is the same, rte channels from Ccarn, no UK HD from divis.
I understand its because UK freeview HD uses DVD-T2 with mpeg4. Saorview is DVB-T with mpeg4. So our LG tvs support mpeg4 and DVB-t but not the newer dvb-t2PaulNThursday 25 October 2012 10:10AM
Here's a weird thing... my Triax TR112 SaorView box happily picks up SaorView from Clermont and FreeView from Divis cos of my two aerials etc.
However - it doesn't find the HD Freeview channels - whereas my Panasonic DVB-T2 equipped TV (and HDD recorder) does from the identical setup.
There must be something signalled on the HD FreeView channels that the SaorView box doesnt like - but it happily ingests all the SD FreeView channels & EPG data. Odd.PaulNThursday 25 October 2012 10:15AM
Another weird thing is that while my Panasonic DVB-T2 HDD Recorder picks up both SaorView & FreeView signals in SD and HD....
My Panasonic DVB-T2 TV only finds the FreeView channels.
There must be some differences in the software that controls the searching/tuning operation on the two devices where presumably some SI/PSI data is being ignored by the HDD so it can 'see' all channels that present themselves - while the TV is programmed to ignore anything other than FreeView multiplexes.
Not really a problem - just a curious observation !PaulN: have you checked the 800-899 channel numbers? PaulNThursday 25 October 2012 11:25AM
@Briantist - I just performed a manual scan of C52 on the panny T2 tele and it is 100% happy with SaorView.
I just figured how I missed this yesterday - I did a full auto/install tune on that TV yesterday morning around 9am and thought it odd the Analog RTE was still on air and I was really only expecting a proper SaorView box to find SaorView muxes.
I tuned the other devices to SaorView much later in the day - so obviously Clermont wasn't running full power early yesterday morning.
BTW - I have just ordered another DMR-100HW recorder for another room - its last years model at a bargain around GBP180 on Amazon right now - SaorView & FreeView SD/HD twin tuner HDD recorder.
Its all good :)PeteLadThursday 25 October 2012 11:37AM
PaulN: triax 112 doesn't look like it supports DVB-t2 which would explain why you are seeing Ccarn rte and no uk HDPaulNThursday 25 October 2012 5:31PM
@Pete - I know the TR112 isnt FreeView certified... the fact it picks up anything is a bonus, but I understand that SaorView is a DVB-T2 system... perhaps a subset of all specs which is why FreeView T2 boxes can ingest the SaorView channels but not the other way around ?
PaulPeteLadThursday 25 October 2012 8:52PM
Saorview is NOT DVB-T2, its DVB-T/MPEG-4.
Freeview SD is DVB-T/MPEG-2
Freeview HD is DVB-T2/MPEG-4
So a regular saorview box will be a DVB-T box which will support mpeg2 & 4. Thus the behaviour you are seeing on your TR112 is expected - no freeview HD because it doesnt support DVB-T2.PaulNFriday 26 October 2012 11:09AM
@Pete - Thanks for clarifying... My knowledge of the NIMM led be to believe that SaorView was also DVB-T2... I hadn't looked at the small print of DVB-T to realise that MPEG4/H264 was supported along with MPEG2.
That explains why the SaorView box can only work with DVB-T FreeView muxes.
PaulPeter HendersonFriday 26 October 2012 10:29PM
Excellent reception of Saorview from Clermont Cairn now with the power increase, and actually considerably stronger than Divis at this location here in Jordanstown Co. Antrim.
Also receing the NI Mux from both Carnmoney Hill and Black Mountain, with Carnmoney Hill being the stronger of the two (getting this off the C.C. aerial). Black Mountain isn't that strong, despite Digital UK's predictions, but perfectly watchable with absolutely no break up.
Very impressed with C.C. though.
Happy days !PaulN: I am glad to hear that it all works now. P. Kieran WardThursday 8 November 2012 11:37PM
Belfast Hi all!
Can I start by setting my location in context – BT14 6NQ! My main TV set is a Toshiba UL863 with both DVB-T2 and DVB-S2 tuners and my HDD recorder is Humax HDR-FOX T2. I have always received good strong signals from Divis, Black Mountain and Clermont Carn and this has continued after DSO.
I have a bit of a problem with regard to Electronic Programme Guide from Freeview and Saorview from Clermont Carn both on the TV set and the Humax recorder. If I am on Freeview I cannot see details of programmes from Saorview and vice-versa. After-all all of the information for both services is being received from both transmitters; I would have thought that both sets of EPG data would be shown.
Am I expecting too much?
P. Kieran Ward
Peter HendersonFriday 9 November 2012 2:56PM
Noticed that myself on my Humax boxes Kieran.
I don't think there's anything you can do about it. It's the only issue on Humax receivers, as far as I can tell. The Humax PVRs can record Saorview and Freeview at the same time so there's no problem there.
The Sony STBs are much worse. No programme information on the EPG for exampler.
P. Kieran WardSaturday 10 November 2012 11:21AM
Belfast P. Kieran Ward: Hi Peter! Many thanks for your info. I would have thought that both sets of data for EPG would have been processed by the receiver and displayed accordingly!
Again thanks!
Regards
KieranP. Kieran Ward: The EPG information for all Freeview channels is carried on all of them. Therefore if you are watching BBC, for example, the EPG information for ITV and Channel 4 will still be available.
Clearly it won't be available across the two platforms: Freeview and Saorview.
From what you describe, your receiver doesn't "take the initiative" and "look" for the EPG information on any other multiplex other than the one that it is currently tuned to.
I'm not a professional so don't know whether there is a way around this. On reading comments online, the Humax devices are well designed, so if they won't do it, then maybe nothing will do it. AdrianSaturday 10 November 2012 11:50AM
Have a panasonic TH-42PZ81B tuned to claremount carn ch 53 but with the change to ch 52 I cannot retune to ch52 any body have a fix?Adrian: Have you done a full reset?
I understand that the transmission power of CC went up at switchover, so could you have too high a signal level now? If so, this may likely show as too low a level or no signal. ADRIANTuesday 13 November 2012 11:46AM
Dave I didnot do a full reset as I had problems with the software on this tv before and i had to download a previous software version so I could recieve the Irish stations from claremount carn .
I believe this software problem is known by panasonic but they have not done anything to resolve it.
Because of this I tried to do a manual tune to channel 52 but only the radio stations are picked up .
I also have an LG tv and it retunes fine .
ADRIAN: I don't think that doing a factory reset would revert you back to the later firmware (software).
Once you have exhausted all other avenues, then a factory reset would appear to be the only thing left.
What options you have depend on the design. In some cases it is possible to delete individual multiplexes or services. Or running the scan through with the aerial unplugged may "blank" the memory. Perhaps due to the fact that the channels are/were tuned in on C53 that some remnant of this still remains in the memory and is preventing the C52 mux from working. I don't know exactly how it works, so that is just my thought and possible explanation should it turn out that a full reset does the trick. Peter HendersonTuesday 18 December 2012 12:38AM
Newtownabbey Saurview Mux 2 is now testing from Clermont Cairn on channel 56, not 57.and it also says C51 and C53 for SV1... Peter HendersonTuesday 18 December 2012 9:58PM
Newtownabbey Well, I did a manual scan on 57 and found nothing Brian.
SV1 is currently on 52PaulNFriday 3 May 2013 6:04PM
Anybody else having problems with C52 from Claremont carn tonight??? Dunno if it's weather related.
My sets are showing very poor signal tonight so maybe my masthead amp has died. Nothing else changed but has been a while since I tried it. I was seeing some errors a couple of weeks ago due to reduced quality but now I have black screens. :-(PaulNSaturday 4 May 2013 1:44PM
Been up in the attic and checked I still have power into my saorview aerial amp. Swapped the amp for another with a little more gain but still I get black screen. Odd as the mast hasn't moved and chances of cable damage are negligible as nothing has changed in months. PaulNSunday 12 May 2013 1:31PM
So this is weird. Today I am getting 100% quality from Claremont carn. Nothing has been changed. So it must have been weather related when it went bad last time - unless something else was interfering on C52. Weird, but hopefully it stays good for the Pro12 final in HD on RTE2 !updates
