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?

Andrew Healy:

Do you mean TV (LCN) channels 22 & 26 (on different multiplexes) or UHF channels 22 & 26?
Whichever, the transmitter isn't listed for Planned Engineering howver here are a number of other changes taking place which may have an effect
Updates and alerts | Freeview
You may find some channels get misplaced in the 800s depending on the retune and have to manually clear things.

Does anyone know when the current works on Chrystal Palace transmitter may be completed? I have had no tv signal for some days.
Thanks.

Kathy:

I'm afraid Arqiva never state how long any particular work will take, some of it may be weather dependant. However, if you've been without signal for several days, there's likely to be another reason as there would be a lot of complaints if it were down that long, which it's not.

if you are in a marginal reception area that could explain it, but you'd need to provide a full postcode for us to check that.
if you unfortunately went and retuned when you had badly pixellated pictures or no signal (never recommended when you'd been correctly tuned) then there's a good chance it's just cleared all your correct tuning, so you'd now have to retune again, and maybe try several times as you won't know when the signals are normal.
As mentioned, if you provide a full postcode, we should be able to give further advice.

Chris.SE: Was there a brief transmission outage last night during BBC1's Eurovision coverage? If so, what was the cause? Or how do I find out about the existence and possible details of recent outages? (Planned and unplanned)? Would help me identify any local issues with reception (eg interference). Regards, David

David Esp:

I can find no listing of any outage, however as per just after the top of the page, the transmitter is currently listed for Planned Engineering.However, I think it highly unlikely that interruptions or a reduction in power would have been made during Eurovision.
As per the post before yours, if you live in a marginal reception area, but also if reduced power was already operative that could be the cause of what you experienced but a full postcode would be needed to check that.

What I didn't mention in the reply to Kathy, was current weather conditions. There's some significant "Tropospheric Ducting" affecting differing parts of the UK very randomly.
These conditions cause signals from distant transmitters in Europe or the UK to travel further and result in interference to your wanted signals. This doesn't always affect all multiplexes at the same time and may not affect all viewers. It can last seconds, minutes or for longer. There is little you can do except wait until conditions improve - or try watching online etc.
Being in a marginal reception area makes you more vulnerable to such problems.

Hi, I live in Central London. I have have had little or no Tv signal for 7 days..at best there is constant pixilation but mostly every 30 seconds it is blank np signal screen. Initially Freeview page stated engineering works on Chrystal Palace transmitter had commenced on May 8th then it was changed to May 15th but no one has any information regarding when works will end.. Does anyone know pls?

Kathy: There is definitely no fault here in South London. Sounds like you have an aerial fault. Are you on a communal aerial, and indoor aerial or your own outside or loft aerial?
Signal strength in SW9 is the normal max.
On another issue I noticed that my Freeview Play enabled TV has ditched the BBC Three and BBC Four channels on Freeview 106 & 109. Instead channel 9 and 23 in the freeview list on the TV show as HD.
Don't recall either the BBC or Freeview warning about this strange behaviour!

Kathy: The latest engineering notice was dated yesterday so it's likely that the work is still ongoing. They never give an end date as it can change if work is disrupted by unfavourable weather or other issues arise.

It's worth checking that you don't have any loose or damaged cables or connections behind your TV, but do not attempt to retune while the work is taking place.

Kathy:

I replied to your first message on the 13th May (above). Please read!
As you haven't supplied a full postcode or any other information about your aerial installation eg. as another poster has mentioned whether you are on a communal system, then it's almost impossible to provide further advice.
If you are on a communal system, check if your neighbours are having the same issue, but in any event you will have to contact your building management to get the matter resolved.

See the last but one paragraph on this BBC Blog.
https://www.bbc.co.uk/med…land
IIRC there was a trial with some Freeview Play devices previously which were connected to the internet, where the automatic swap would take place. Your set may be one of the models which did this.
At present I can't find the link to that information, I'll post it later if I find it.
