As of today (Friday 19th October 2018) there is a strong likelihood that TV reception problems may be experienced by some people who have their TV Aerial pointed towards the Ridge Hill transmitter near Ledbury.
This transmitter serves large parts of Worcestershire and is occasionally susceptible to interference from other TV transmitters when certain weather conditions prevail, causing picture breakup or in some cases, total loss of TV reception.
Looking at the current weather / atmospheric pressure readings today would suggest that this interference is caused by the current High Atmospheric Pressure which is currently centred over the southern half of the UK.
Weather forecasting and predictions strongly indicate that this High Pressure may persist until the middle or end of next week.
While this current spell of cool but settled weather persists there is one very important thing to remember, if, at at any time, now or in the future you ever experience pixelation / breakup or a sudden loss of TV channels....
Many people, now know how to access the "Auto re-tune" in their TVs setup menu, unfortunately I'm often finding that customers use this new found knowledge as a "cure all" for any problems that may arise with their TV, whether that be reception related or otherwise.
Re-tuning a TV during periods of poor reception or loss of picture will usually only delete the TVs memory of frequencies / channels which were originally saved from the transmitter that your TV Aerial is pointing at, creating a bigger problem, often meaning that you will be without TV pictures for much, much longer than people who didn't re-tune their TV.
With the exception of an on screen message suggesting a re-tune is necessary or advise from someone like myself or TV retail shop etc, a willy-nilly re-tune of a TV in the hope that it will restore the channels should be avoided and is almost always counter productive.
The on-screen message "Weak or no signal" which sometimes appears on a TV screen while experiencing poor reception is NEVER an invitation to re-tune the TV!
