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
https://www.bbc.co.uk/rec….jpg

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 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 to your multiplexor info sometime?
For example, some of the HD programs appear to be on Ch30 rather than 48.

Thanks

Did you mean ? or 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 on UHF that's 482MHz at .
See Channel listings for Industry Professionals | Freeview for which are carried on which multiplex.
