The symbol shows the location of the Crystal Palace (Greater London, England) transmitter which serves 4,490,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Crystal Palace (Greater London, England) mast?

hi,
I now have no picture.the reception is dark and snowy. I havent switched yet as I rely on the crystal palace transmitter. Sometimes the weather makes channel 5 freeze, but this is the first time all channels have gone. Is anyone else getting this? I have a rooftop aerial.

Happened to notice that CP seems to be experimenting with ch22 (analogue ITV) signal strength lately. Daytime strength as measured by our system (in North London, line-of-sight except for pesky City of London towers halfway between us and CP) has always been in the the low 70s (in units of percentage of ideal signal? Who knows... Anyway, below 80 on analogue frequencies results in a very poor, unstable picture) but is suddenly now in upper 80's (perfect picture). Nighttime strength is back in 70s. Weird.

Actually, I'm wondering whether ch23 (analogue itv) is temporarily being broadcast from a different physical location (a different point on CP's tower, or maybe it's being relayed from Croydon?) while they get set up for post-DSO channel 23... I've always suspected that our poor ch23 reception was caused by our aerial just happening to be in a node for that frequency. An aerial a few feet away from it does fine, so even a very slightly different signal source location would change things. Anyone know?

Wow. As of just this minute signal has dropped back to its "normal" level, i.e. 72% and virtually unwatchable. Guess CP's DSO tech guys are clocking off for the day and have to put things back to normal for the night...

Just read that Croydon has, indeed, always been set up to run as a backup for certain Crystal Palace channels, including ch23 - so it looks like the DSO engineers are using Croydon for ch23 during work hours as they get CP's ch23 transmitter ready for when it will be used for the BBCA multiplex.

Hi all
I am in Se18 ( plumstead area ) I have an aerial in the loft facing south west towards shoots hill (crystal palace is over on the other site which is parley why we have such a poor signal in se18 .
A few years ago i put foil on the wall just behind the aerial which had improved the reception in the loft. Over all the reception has improved recently .
What i have notice is we are also getting transmission from multiplex from BBC Bedfordshire. I can watch the local news on channel 1 ( BBC 1 London south east ) as well as on channel 800 which give me BBC 1 ( look east - Bedfordshire ) ? I could only assume the multiplex for BBC Bedfordshire has much strong signal and is must be bouncing off shooter hill . When we have lost BBC 1 from crystal palace. I can still get a very good picture from Bedfordshire. The multiplex has BBC 1, 2 cbbc ect. On channel 800 to 804.
BBC look east Bedfordshire in on channel 800 and BBC south east London is on channel 1 is because the TV is set to the post code SE18 1RN.
