Why is the TV signal so poor in Kettering, all BBC are just black and have been so for a few days now. We have lived here for about 4 years now at this address. The signal is so poor, we can't view lots of Free View channel's all the time, & we can't even see the programme information of what on as it never works as the signal is so bad. We are having to constantly scan the channels to try to get it better, but it never works. Don't know why we bother paying for our TV licence as it's not worth the money with just repeat repeat repeat all the time.

Mr Charles Foreman:

Did you read the post before yours? The transmitter is on Planned Engineering with the possible effects exactly what you are seeing.
Additionally, if you were correct6ly tuned, it is NEVER a good idea to retune when you have very weak signals or no signal or badly pixellated pictures etc. The most likely effect in most cases is it will just clear your correct tuning and so will be missing channels. Sometimes you might get tuned to very weak signals from another transmitter which will not stay constant.
You then have to retune again when signals are normal, which you may not know when, and so have to try several times.

Depending on your precise locale you may not be predicted to get very good reception of the SDN/COM4 and ArqA/COM5 multiplexes in any event. We'd need a full postcode to advise on that.
