Sawbridgeworth Hi,
Where can I find a table of TV stations with their channel numbers for the Crystal Palace transmitter?
I have an old digital TV that only has space for 100 TV stations. After doing an automatic retune, some TV stations are missing such as BBC News 24, ITV News 24, Sky News, virgin 1 etc. They are missing because the radio stations 700 etc are stored at 70, 71 etc. I'd like to tune into these news stations manually.
Cheers, Ian Gould.AlistairThursday 7 January 2010 9:35AM
Hartlepool I have to try and tune a PC card to a tv channel to find a Linux software bug.
The only problem is that the script ask for an unrecognisable format e.g. E2,S22,SE15.
If I wanted to use UHF channel 33, is there an "S" number for that?John TidyThursday 28 April 2011 12:05PM
I live on the far side of Blackheath from the CP tx and had perfect reception until last Sept when suddenly I couldn't receive a watchable signal on any of the channels on Mux1 (DTV Ch25) i.e. BBC One (London), BBC Two (England), BBC Three, CBBC & BBC News. After a lot of web-searching, inc looking into freesat, fiddling with the aerial (height is critical) and putting up with it eventually the quality returned to normal.
As of a week ago we are back to having exactly the same really poor reception - same channels, same Mux and same symptoms , i.e. can have either this Mux alone with just acceptable quality, or everything else with good stable pictures and sound. but not both.
I found a spare aerial (they are both Wolsey ColourKings) so now there are two on my 20ft pole, but even that's not great nor acceptable in the long-term.
Before you tell me to change the aerial, remember it performed perfectly for many years before this all started about six months ago.
Please help! All and any suggestions welcome.Mike DimmickThursday 28 April 2011 3:30PM
John Tidy: The problem is that grid aerials don't have very much gain, and have a fairly wide acceptance angle. At that distance from Crystal Palace, you don't need the gain, but you're still at risk of picking up co-channel interference from other transmitters, as well as increased likelihood of too much signal overall.
I would consider getting a small log-periodic aerial, which have better directional properties. You might need to add an attenuator to reduce overall signal levels.

It could simply be due to weather conditions, of course: there are many other transmitters in the country using the same channels, which are normally blocked by terrain but in the right weather conditions, the signals bounce off the atmosphere and cause interference at far-distant locations. lauraWednesday 11 April 2012 8:33PM
i re-tuned my freeview box like told too and lost all the bbc channels? will i get them back? thanks (i live in surrey- just by gatwick).Mike DimmickWednesday 11 April 2012 9:46PM
laura: Check whether your box supports 8K mode. There's a list of some equipment that is known not to at 
http://www.digitaluk.co.u…ment . If it doesn't support 8K mode you'll lose all the remaining channels when switchover completes next Wednesday.
There are still some boxes around that have problems with the larger Network Information Table. This problem shows up when you retune, although you'd have had to not retune for more than two years now. Again, a partial list is at http://www.digitaluk.co.u…tnit .
Do make sure you do a full retune - also called factory reset, first-time installation, virgin mode or default setting. Some boxes even seem to need to have this done with the aerial unplugged to ensure they're completely cleared out before doing it again with the aerial connected. For information on your particular box, see 
TV Re-tune productmanuals .
If that doesn't explain it, you could have too much signal. If you're sharing a communal aerial, get the landlord or management agent to adjust the levels. If not, try unplugging any amplifiers or boosters that you have. If you don't, you might need to add an attenuator to reduce the levels. Andrew HealyFriday 4 May 2012 2:56PM
Ashford Sirs,
is the D3+4 multiplex, at Crystal Palace, unmdergoing something mechanical ? The signal from this multiplex fails repeatedly and fouls my Alba TV, when I can reach it. Is this multiplex set too high or low ?
I have had this problem since full switchover (DSO).Andrew HealySaturday 5 May 2012 11:07AM
Ashford Mr Fletcher,
when my picture fails, I am using a loft aerial and the signal strength goes so near to zero that my screen pixellates. BBC and Radio transmissions are fine, but, everything from D3+4 is shot. And no, a fully external aerial is not an option- I lodge.Andrew HealySaturday 5 May 2012 4:09PM
Ashford Have found out that a nearby bloke is a radio ham. This is a known source of interference, so have ordered a DTI (digital TV interference) filter, from Amazon- this should remove all ham and possibly taxi radio signals. Many thanks for your help, Mark.Andrew Healy,Ashford.No problem whatsoever,pleasure to have been of assistance to you ! Susan PritchardSaturday 26 May 2012 4:40PM
Woking the signal from channel 26 Crystal Palace has been very poor for the past 3 days meaning a lot of pixellating on the channels it serves. Have tried auto and manual retune and checked cables etc. but no improvement. Is there a problem with this channel at the moment?Charles WSaturday 9 June 2012 10:20PM
London I have the same problem as Susan. Channel 26 Crystal Palace has become unwatchable.
Briantist - thank you for that link, but unfortunately I can't see that anything has changed that would affect reception (eg games console)
If both Susan and I are having the same problems, and in the same time period, I wonder if there are more in this situation?jb38Saturday 9 June 2012 11:17PM
Charles W: you are located at only 2 miles away from the massively high powered transmitters at Crystal Palace and as such your TV or boxes tuner could be suffering from being grossly overloaded depending on the aerial system being used, for a test try a set top aerial or alternatively a short piece of wire (about 12/18" or so) inserted into the inner part of the aerial socket.

Telford I am in The Wrekin transmitter area (very close but in the shadow of Ketley Bank.
I have only been on Freeview for a week or so
Suddenly today all programmes on COM6
ArqB Channel 47 (682 mhz) have gone.
The signal strength is showing as 60 to 65% just as before but no picture/sound except for an occasional badly pixilated frame.
All other channels are ok
Any ideas please?BenSaturday 20 October 2012 9:22AM
