Richard:
Others have had similar issues. There has been moderate Temperature Inversion/Tropospheric Ducting affecting large parts of the UK for several days, it sometimes accompanies high pressure.
Do NOT retune, it will more likely remove your correct tuning.
These conditions are predicted to ease late on Wednesday by the end of the night
Despite the incorrect spelling, this link does work - simple technical explanation

Essentially it results in interfering signals from other transmitters in the UK or Europe reaching you and so your wanted signals are disrupted. It won't necessarily affect all multiplexes or necessarily at the same time if more than one. It can last for seconds, minutes, sometimes hours or longer.
The BBC have had a warning on their Works and Warnings page for a few days, and Freeview had added one on Wednesday (better late than never!) but at that time it was then mainly affecting the S & SE.

Hi
Are you planning an update to your multiplexor info sometime?
For example, some of the HD programs appear to be on Ch30 rather than 48.
Thanks

Derek: There have unfortunately been errors in the information on this page for a long time, the only person who can correct it is the owner of the website. Crystal Palace has never used UHF channel 48, PSB3 has been on C30 since digital switchover was completed in 2012.

As the site owner hasn't had time to update the errors, I posted this (one of many) just over 12 months ago -
In the multiplex order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6, COM7, Local multiplex, the UHF channels for Crystal Palace are as follows
C23, C26, C30, C25, C22, C28, C55, C35 (London Local mux).
See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex.
Worth repeating now and again for those that aren't aware.

Hi
I find this page very useful but are you going to update it sometime? In particular it show HD programmes on C48 which have now moved to C30. There may be other changes too.

David Belmar:
Did you mean frequency? or Channel LCN in the EPG? All LCNs in the range 25-82 are moving down one, so they'll be 26-83. Davejavu moves from 23 to 25. BBC3 SD will be on 23 and HD will be on 109.
So Food Network will move from 42 to 43.
See BBC Three launches | Freeview for the official detail.
Food network is carried on the ArqA/COM5 multiplex on UHF C22 that's 482MHz at Crystal Palace.
See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex.

The signal for BBC fOUR hd and some other HD channels ( abc news, RT ETC ) has disappeared.
I have carried out retuning as recommended and manually retuned by get no signal on Frequency 55
which was the BBC fOUR FREQUECY WHEN i RETUNED last year.
My postcode is W11 3LT and communal roof aerial in not blocked by buildings etc.
I get other HD channels and bizarrely the new BBC Three .
Is there a temporary probable at Crystal Palace or have BBC Four HD programs no longer avaialable in
Central London ?
