High pressure isn’t something that is easy to detect. It’s usually associated with hot weather but can happen at any time of the year.  Take a look at our video for more information. 

It can cause two potential problems. The first is that you receive a weaker signal, as the signal from your local transmitter is lifted higher into the sky. The second is that the signal from a distant transmitter interferes with your reception. 

How to check for high pressure 

The BBC monitors for high pressure and will publish a notice on theWorks & Warnings pagewhen high pressure could be problematic to viewers. 

What to try if you’ve lost reception due to high pressure 

Check theWorks & Warnings pagefor a high pressure notification. If there is high pressure happening, all you can do is watch by another means, like BBC iPlayer, or satellite until the weather changes. If there is no high pressure warning, try ourproblem assistant tool, where you can check for transmitter problems and work through troubleshooting guidance. 

Avoid retuning 

Do not try retuning when there is high pressure, as you can lose services or store signals from a distant transmitter. If you did try a retune, you’ll need to do it again once the high pressure has passed. We suggest performing amanual retunewhere you can select the transmitter you receive service from.
