Kim:
In my many years of experience with both analogue and digital TV, the broadcasters have never announced anything about atmospheric conditions as that is not in their remit - it is a matter for weather forecasters such as the Met Office to report about. In the days of Ceefax/Teletext, booth BBC and ITV had pages reporting about transmitter issues and often included weather effects. Sadly, they got rid of what was a very useful service and replaced it with a very truncated attempt that had nothing about transmissions and conditions.
So the broadcasters are not being secretive at all. It is up to you, me and other viewers to do the research and then to understand the implications of the results.

It is possible that your aerial system has a problem that lets water into the cables which would affect some signals more than others. The solution is to ensure that all the cabling from the aerial to the TV is in perfect order and not letting the rain in.

Mrs G Hall:
If you receive your programmes from Malvern, then it is reported as being on reduced power during engineering work. As you have not given a full post code we cannot tell if that is significant for you.

MikeB:
Yes, I'd noticed that too. Just responded to one such for Malvern and another for Rowridge.

Firstly, Malvern is reported to be on reduced power during engineering work. Secondly, this website is not connected with the transmitter operators. If you wish to contact then look at https://www.arqiva.com/co…us/. They are responsible for transmitter maintenance, etc.

Hillary Woodward:
Further to that said by MikeB, I strongly suggest that you make some investigations first. Check what the reported signal strength is for all the available multiplexes and then report them here. Secondly, check that all the connections in your aerial system are in good condition and the plugs fully inserted. Thirdly, check that your aerial has not moved or been damaged.
Finally, help us to help you by giving your full post code so that we can check what the reception and transmission conditions are for your location.

Geoff Hall:
As most people using Malvern are not having any problem at all, that suggests strongly that you have a fault with your system. You need to thoroughly check through all the connections.

Sasa:
Your relative should check that they are tuned to the Emley Moor transmitter. That uses channel 47, 44, 41, 51, 52, 48, 32 and 34. If they find the TV is tuned to other channels then they are on the wrong transmitter and will experience problems, so will need to retune manually.
ITV3 from Emley Moor is in the multiplex on channel 51 along with several other services, see Which Freeview channels does the Emley Moor transmitter broadcast? for details. If they are getting these other services OK then there could be a fault with their TV set.

Michael Brookes:
Though you have not given a full post code, which is needed to determine which transmitter you use and what the reception conditions are like, it rather sounds as if you have a problem with either your aerial system or the TV set. Start by checking what the signal strengths are on the multiplexes used by your chosen transmitter. If they are over 85% then they are probably too strong, which gives the symptoms you describe. Then check all the connection between the TV and the aerial. They must be in good condition and tight.
Further advice depends on your full post code and the test results.

Glad that sanity has returned to your household.
When dealing with signal reception problems both the strength and quality are important. Too much signal strength is as bad as not enough, or sometimes worse. Quality will always vary but the critical issue is whether it falls below a required level so that the 'decoder' can sort out what all the digits mean.
'F' connectors are becoming the preferred method of connection aerial leads. They are reliable if fitted correctly.
The frequency range used by 4G is in the bands 800 MHz, 1800 MHz (1.8 GHz) and 2600 MHz (2.6 GHz). So any transmission that is close to those frequencies could be affected by interference. In your case PSB3 on ch58 and COM5 on ch59 could be affected, so a filter may be beneficial if the 4G transmitters are close by.
