I was previously able to receive sky 3, uk tv history and other channels on my goodmans digibox. Recently I cannot receive these channels although other channels are crystal clear. Any suggestions? I live in the Dundonald area.

Kevin Henderson: are you using a wideband aerial? Multiplex C is broadcast on an out-of-group frequency, and requires a wideband aerial to receive it.

I live in the warrenpoint area and cannot pick up any signal on my freeview box is there anything i could do to get it?
Briantist
Tuesday 12 December 2006 1:58AM
Joe: check to see if you can see any sort of analogue signal from your aerial. If you can't at all, then there will be a disconnect. If you can, but the picture is poorer than normal you might have a damaged cable, connector or aerial. If everything seems fine on analogue, try scanning for channels again and if you have nothing your box may be at fault.

From the 'before and after' tranmission frequencies above it looks like Divis and the other N. Ireland transmitters are currently transmitting all 6 muxes, but will only transmit 3 after switchover. Surely this can't be right, as it's mentioned elsewhere that if you currently receive all freeview channels you'll continue to do so after switchover?
Briantist
Tuesday 2 January 2007 12:41PM
Victoria: Ofcom have not published the actual frequencies, but this transmitter is going to broadcast all six multiplexes after switchover.

I live on the West Coast of the Isle of Man, and although I'm not supposed to be able to, up until two weeks ago had been suucessfully (with the aid of aerial amplifiers) receiving most MUX's, although MUX 2 was sometimes too weak. However, since about two weeks ago, and despite a lot of work by a local aerial firm, MUX's A-D are now weak, although Mux 2 has strengthened. Having just discovered the above list, I'm not surprised I'm having problems! What puzzles me is what's changed. Do the MUX strengths change, or have they rotated the transmitter to change the transmission pattern, at the expense of my signal strength. Or are the aerial people struggling? Sorry about the message length!
Briantist
Wednesday 7 February 2007 10:34AM
Al Lawrence: changes in atmopsheric conditions and changes to signals of very distant transmitters cause unpredicable effects outside the designated reception areas. If possible try raising the aerial up by a few more meters

Hi, I live in the Dundonald area. I've recently installed an 8-way amp/splitter from my aerial to distribute the signal throughout the house. The reception was fine before, but after feeding through the amp I've lost Mux D. I think the aerial is a high-gain (it's got a green cap on the end). I'm stuck! Any suggestions? Many thanks!
Briantist
Monday 26 March 2007 11:10AM
Carl Irvine: often boosters cause this problem to happen. You will probably find using a new amp/splitter will solve the problem.
C
Carl Irvine
Monday 26 March 2007 12:55PM
Briantist: Thanks for the reply! I'll give that a try. Would that mean that the amp/splitter is faulty, or just not very good? I used an SLx8 from B&Q, so if it's faulty I'd like to just exchange it! If it's probably not faulty, is there a brand that you would recommend?
B
Briantist
Monday 26 March 2007 1:53PM
Carl Irvine: It may be a fault, but sometime it's just the device. can you return it to B&Q to exchange for a different model?

I see a post from someone living behid the Scrabo hill in Newtownards. I have just moved to this area and I cannot get freeview :-(
I have freesat but it is crap - it only comes to one TV in the house - I plan to connect it through to the rest but haven't done this yet (well not with wires - I am using wireless senders at the minute). Freesat only has some of the channels as well - I think it has the free-to-air ones, but freeview has these plus the free-to-view ones (or the other way round)......
My question is..... all the aerials here are pointed towards Newtownards. We must be getting our signal from a repeater station in Ards as opposed to from Divis..... does anyone know any details about this, and anyone I can contact to ask when it will start repeating freeview frequencies as well?

I had seen this link after submitting my last post.... I think it does answer my question, unfortunately :-( I am amazed the dates are in 2013... I thought everywhere was to have freeview by 2012!! I am also amazed that only a subset of the channels will be available after 2013.... this seems to be an absolute farce to me!! From the map I still think Scrabo is between my house and the transmitter - all the aerials in my street point into Ards which seems to me to be away from this transmitter... it must be repeated out again from somewhere within Ards which is in the coverage area of the transmitter. I have since spoken to neighbours and it seems even if I put up a good aerial all I can expect to get at present is channels 1-4 (not even 5!!!). I have sent some mails to work out my options.... it is either going to be ditch all TV and stop paying my licence fee, or subscribe to sky to get better channels and also cable this up to other rooms with old sky boxes to give freesat in those rooms :'( Thanks for your help

Kingsley
Thursday 26 April 2007 3:45PM Newtownards
Do sky not still offer free installation and box? I think it would be better to go for that..... you get the equipment and a lot of channels for £15 / month ... then if you want to you can cancel after a year and you end up with freesat... and that has cost £180 overall (i.e. not a lot more than the freesat install which would give a lot less channels for the first year).
I have heard about the freesat from the BBC but don't know much about it... do you have a link to a website?
Briantist
Thursday 26 April 2007 6:37PM
Kingsley: BBC Freesat has not launched yet, but see www.bbc.co.uk link icon BBC Trust - "Freesat" closed consultation - and you have spotted why Sky charge £150 for Freesat!

hello
i to live in newtownards and was able to get all freeview channels untill recently when all the chanels on mux d decided to go by by. i was thinking of using a masthead amp to see if this will boost the signal. i have a wideband aerial all other chanels are ok. checked thru sony freeview box all muxs seem to have good signal quality wxcept mux d which is very bad is this also linked to below average output from divis.
Briantist

hello
sorry but no vcr etc are connected to the tv it seemed a sudden loss of mux d
may try replacing aerial down lead but have checked aerial for connections etc.
asked neighbour and he uses a masthead amp in his loft. aerial lead has been split using y joint may also try fitting a splitter first but think amp with two outputs is the way to go. after using y joint thihgs were ok for some time. any other ideas would be very helpfull.

aerial is on the roof it has not moved but tryed another wideband high gain aerial but had the same results all channels have good signal and good signal quality even when checking on pace freeview recorder chanels have approx 65% strength but both boxes are failing on mux d with low signal strength and bad signal quality i wonder if a filter of some sort is required in aerial feed also i have the black sat cable through out,

Wednesday 6 June 2007 11:20PM Newtownards
Quick reply the problems have now been
sorted believe it or not it was the splitter/connectors thes were replaced with a proper type box now have mux c back though it is at lower power so sometimes there is breakup. so moral to story is use good quality connectors and you should be OK

Hi

I live in the Markethill area and manage to receive a range of freeview channels, however I am particuarly after E4 and More4 and for some reason I cannot pick them up. I also cannot pick up ITV1 2 or3 although I can pick up channel 5. Is the problem down to these programs being in the low transmission power zone or if I move my ariel slighlty would this help?

My aerial is wideband, should I switch to group K?

Bill McAskie
Briantist
Tuesday 7 August 2007 10:48AM
Bill McAskie: If you are missing just multiplex C from this transmitter is would normally appear that your aerial is NOT wide-band. If it is (they have a black band to identify this) you may have local interference on C48 from a VCR, games console or similar. Try powering of any devices that might have such an output (analogue TV picture) and rescan to check.

I live in Maryhill, G206UG and have connected my freeview box using a cable from living room ariel wall socket, and fed it up stairs to the bedroom. But I cannot get ITV, E4, etc. What am I doing wrong? Do I need a wideband ariel, and if so, is it just a matter of replacing the existing ariel?

Thanks to anyone who can help..

Sharon...
Briantist
Thursday 9 August 2007 8:42AM
Sharon Jebb: Probably your aerial is too small to receive the 64QAM-mode multiplex 2 channels. If you can watch multiplex C and D, your aerial is wideband already.

Hi. Wonder if anyone might have had and solved these problems!
I live in Ballymena BT43. i have RTE aerial bbc high gain aerial. This is fine when i use power amp and run to my TV. 1st problem occurs when i split into a powered 8 way splitter. i loose signal on itv bbc (teletext is poor).
so i have to not connect the splitter. to get all terrestial channels. 2nd Problem is when i then connect my new free view box i am not able to get the ITV MUX...... But if i do not use my power amp (which i need for rte and bbc to combine) i can indeed pick up all the freeview mux with reasonable strength. So i have good reception in my roofspace as this is where i carried out my checks. but i would like to be able to combine rte and bbc ... and be able to get freeview and then split the signal in my roofspace at point of entry. and finally send from there to any chosen point... without having to run two cables to each Tv.
Any ideas about power amps or splitters to achieve this> Thanks. Greg.

Thank you Briantist!
HiAGAIN. SORRY. i have had a look through the section suggested and other information also. I do not see any information or threads at all that suggest how i could solve my problem in the roofspace and then leave ready to distribute to tvs from there. I could run the digital freeview but as i said in my last post this would then require two cables to each tv point that i wanted to get the freeview on. Seems also that local tv people in town R unsure or really do not know how to combine RTE/BBC while getting a suitable freeview OR... if they do.. they will not tell(i suspect the first).
Still Thanks for reply... any other info/suggestions gratefully received. Greg

I, in common with many people at the seafront in Girvan,KA26, get reception from the Divis transmitter in Northern ireland. This involves a set top box an amplifier and a proper aerial installed professionally about three years ago.
This has worked with very little problem.
The frequencies we received were 23,26,29,33,34.
Since Saturday 1st December only 34 seems to be sending a signal.
So viewing is restricted to analogue channels and UKTV History,Film 4 and a few others. Can you shed any light on this or put me i touch with someone who can?
Briantist
Tuesday 4 December 2007 8:59AM
tom de lussey: You are not technically in the transmitter's reception area, so I would advise that you contact the professional installer that supplied the installation in the first place.

I too live in the Dundonald area and found that as of recently Mux D has become unwatchable.
Is it not a little bit strange that more than one of us are experiencing this problem, It had been working quite well up to that point, I notice the transmission power on that frequency is the lowest of the muxes. Has that changed or has it always been that low?
Briantist
Sunday 30 March 2008 2:54PM
Jonny L: The multiplex configurations have been the same since Freeview started. Digital TV reception tends to be all or nothing, so a slight drop in signal level will go from perfect reception to no reception. Still, please check www.ukfree.tv link icon Single frequency interference | ukfree.tv - independent digital television and switchover advice, since 2002 for help.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
