Like the above poster I was also able to recieve all ITV, 4 etc chanels with excellent reception, (IP9 area) nothing has changed my end and as it is all my neighbours as well that are affected with freeview I assume that its from the transmitter.

We would all be very grateful if you could adress this issue and fix it so we may once again enjoy a good reception

Its choppy and pixelated at best and has no signal at all at worst making none of the chanels watchable.
PS we have no sky vcr games programs or boosters, just freeview boxes, tv's and aerial, and as I said before it was all working just fine.

Hi Briantist I knew you were going to say that, which might explain mine but not my neighbour who has his outside the roof.
Apart from a few pixelated glitches at 5pmish today all itv and chanel 4 more 4 etc are working perfectly with the aerial still in the roof space and the same for my neighbour.
Maybe there was some work going on and the power was reduced or something, but as long as they keep it like this and pointing this way we will be ok :) like we were before.
Many thanks for responding and at such odd hours too, do they keep you working 24/7?

you need to upgrade your aerial fly leads if you have not already to digital type. the ones sold in some shops are very poor, best solution is to use new plugs and satellite cable double screened type with the foil in it.
go from the wall plate direct to your digi box.
or if you can change the cable from you aerial if you have a wide band aerial.
also another way to get over poor cable is amping the signal before it goes through the cable this means putting a quality amp near the aerial and a psu at the tv end.
but always try a digital aerial if you can first.

Richard: You're an "Aerial installer" and claim to need "digital type" "aerial fly leads". There's no such thing as a digital signal cable!!!!

Brian,

I'm at post code ip12 4hr which I know is right on the border of the sudbury signal. I have wide band aerial, mast booster and high quality fly leads. I can get a full signal on ch 39 but nothing else (ch 48 occasionally appears but signal strength tends to fluctuate). My neighbour has the same setup and gets most if not all of the freeview channels. Only difference I can see is that his aerial is about 3 degrees different to mine. Is the exact alightnment of the aerial critical or could it be something else such as a more sensitive freeview box?
Briantist
Tuesday 26 June 2007 5:50PM
Jonathan: I suspect it might be the height of the other aerial, rather than the direction being out by three degrees. If it's a Class I (ie, 100-element) then they are very directional, the lower the quality the less the directionality.
J
Jonathan
Thursday 28 June 2007 9:00AM
Thanks. His aerial is about 1-2 m higher than mine but I think it is a wideband but not class 1 certainly doesn't have the 3 central parts i have seen on other xlass 1's. My pole is as high as it can be safely so is there anything else I can do or do I just have to wait until the signal power is increased after switch over?
Briantist
Thursday 28 June 2007 12:00PM
Jonathan: Unless you can see the coloured marker on an aerial it impossible to tell if it grouped or wide-band, the aerials look otherwise identical. Can you extend the pole by adding on an extension? Without a line-of-sight you may still not get the signals after switchover.
J

Saturday 30 June 2007 2:58PM
I have put the aerial as high as I can. The thing that is really bugging me is how come i can get channel 39 at full power and yet not channel 48 even though they both are outputted by Sudbury at similar levels. Any ideas?
J
jonathan
Saturday 30 June 2007 3:09PM
Sorry forgot to mention in previous post. Is it possible that my antiference distribution amplifier in the loft is blocking channel 48? If so how do i check? if i switch it off the power to my mast head amplifier also goes.
Briantist
Saturday 30 June 2007 5:58PM
jonathan: it's not unheard that amplifiers block or wreak a signal by accident. The best way to eliminate is to physically remove it by disconnecting the "in" and "out" cables and joining them together.

Hi -

Like everyone else here, I was able to receive (at my postcode CO10) quality signal for ITV 1,2,3, and 4, along with channel 4 and most of the related channels: film4, 4+1, more 4, etc. Now they have all disappeared over the last month, and seem to have been replaced with the (crap) SKY3 and and load of useless shopping channels... what is going on? Nothing has changed at my end in the last 18 months.
Briantist
Sunday 1 July 2007 6:24PM
k flanagan: You have lost only a single transmission signal, multiplex 2, which carries ITV 1, 2, 3, 4, CITV, C4, More4, Film4+1, E4 and Setanta Sports - are you using a loft aerial? Sky Three is on multiplex C (along with Sky News, Sky Sports News, E4+1 and UKTV History). See www.ukfree.tv link icon http://www.ukfree.tv/muxmap.php - so this is not a "replacment" at all. If you have a loft aerial, relocate to the roof. If your aerial is already on the roof you may need to check for interference.
Briantist
Sunday 1 July 2007 6:32PM
Richard: Have you got a wideband aerial? If you havn't you won't get multiplex 2 or C.

Just purchased a brand new sparkling 50", set up the DTV only to find it intermittently lost the same channels as everyone else is having trouble with. My post code is CO5. Looking at the other postcodes involved it seems a pretty widespread interfering signal, if that's what it is, and how come it only affects the ITV services?

Hi,

Has anyone got any idea why I can see every service from multiplex 'A' except Setanta Sports? I have a card and CAM, and the TV doesn't report it as "scrambled" (as it does with Eurosport from the same mux) it just says "Programme not tuned".

I seem to have every channel apart from this one. I thought if you could receive a particular multiplex then all the channels within that multiplex would be received equally.

*confused*

Saturday 18 August 2007 4:13PM
Andrew: It's not on multiplex A, but on multiplex 2, as shown at the top of the page! Please also see www.ukfree.tv link icon Welcome to Setanta Sports | ukfree.tv - independent digital TV and switchover advice -

Whoops... Oh well, the same question applies for Multiplex 2... I get all those other channels (ITV, etc) but not Setanta sports...

I don't get it.
A
Andrew
Sunday 19 August 2007 12:09AM Colchester
Yep, I gave that a go and no joy. My understanding of DVB-T is obviously not as good as I thought it was, because I thought if you could receive any channels in a particular Mux, you could get all of them.

Might try putting the aerial on a higher pole.
Briantist
Sunday 19 August 2007 11:24AM
Andrew: You certainly should be able to watch the channel, but I suspect your box is detecting it as a "encrypted" channel when you scan and is helpfully ignoring it for you. Can you ensure you scan when the channel is in free-to-air mode. Also, check the 800-899 channel range as the box may have stuck it there... It's not the fault of DVB-T, but of the box you have.

Hi, I'm in CM1 3JB post code area which supposedly is a difficult digital area however I get all channels solidly from Sudbury if I use my original 'On Digital' box but if I use the inbuilt Freeview tuner in my TV I get all channels providing its not raining when I usually lose the ITV channels on one of the multiplexers - is this down to a combination of receiver sensitivity and signal degradation due to rain?
Briantist
Tuesday 21 August 2007 12:37PM
TerryC: I'm afriad I can't really say without your full postcode. The ITV channels suffer from the 64QAM transmission mode, please see www.ukfree.tv link icon Freeview modes | ukfree.tv - independent digital TV and switchover advice and www.ukfree.tv link icon Loft aerials | ukfree.tv - independent digital TV and switchover advice
Briantist
Tuesday 21 August 2007 12:41PM
Steve: The original ONdigital boxes had more sensitive reception equipment than many cheaper modern boxes (despite being very, very slow). ITV channels go first because of the "64QAM" mode they use for transmission - www.ukfree.tv link icon Freeview modes | ukfree.tv - independent digital TV and switchover advice - if you are on such a cusp you may find a booster attached as close to your aerial as possible may restore the services, but you might want to check all your cables and connectors are in the best possible order and your aerial is correctly aligned.

I finally got it working. I had to get Setanta to send the card authorisation as their automated website system had failed to transmit the keys the first time round. The completely unhelpful messages from the TV just made diagnosing the fault much harder!

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.
