Steve B:
A signal strength of 100% is too much and will cause problems, that may be the cause of your problems. You need to reduce the strength to between 70 and 85% ideally. You may need to try fitting an attenuator to reduce the signal levels.

In my considerable experience in the TV industry, 100% is ALWAYS too much. Get used to the idea of being wromng sometimes.

100% leave no leeway for variations in signal streng5th and many tuners are not able to deal with excessive signal strength. Hencw the advice to not have 100% strength. If you do have then there can be occasions when the atmospheric absorption reduces (less moisture for example) so the strength increases. If there is no leeway then that often results in loss of signals. So keeping it well below the limiting strength is far better than risking having too much. It has been so since the days of analogue transmissions and it is actually more critical with digital transmissions. Knowledge of RF transmissions and what affects them is vital,

Get a life. Read what I said again and you'll realise that what I said was a general comment on why 100% is not good.

I quoted from the information provided to me by the design teams of 2 diffwerent TV manufacturers with whom I am acting as an independent consultant and have done for several years. Between them they have far more knowledge and understanding of the real world of TV reception. I cannot fault them in their knowledge and understanding.

Hi
Would I be right in thinking that a Freesat account is not needed if you do not wish to use a 'smart' phone to control the box? My 'old' Freesat box didn't have the facility and I would never want to use it. I would only use the remote control supplied.
Thanks

Mazbar:
The engineers who carry out the work at the transmitters do not come into contact with members of the public as a rule so they are unlikely to postpone their work. You may need to consider you own health security in light of today's Government announcements.
