Which companies have run the Channel 3 services in the Crystal Palace transmitter area
brian: I would reduce it more than just that needed to get a stable picture (assuming that too much signal is the issue).
Being "just below" a level that is too high could be an issue if the level increases slightly (due to the weather etc). Leave room for this.
The picture isn't better when the level is higher, thus the objective isn't to get as near full signal strength as possible.
...Yes I await your news. Just hope that your dad hasn't paid an installer to add an attenuator.

Just so you konw the attenuator arrived in the post the next day.
I was about to fit it when I noticed the picture was fine on the D26 MUX. Four days later and it is still fine. The problem was definately too much signal as I can see the signal strength is slightly down on this MUX compared to the others.
I will keep my £3 investment in a safe place lest the problem occurs again !
Many thanks for your support and advice and I have noted your comments about signal strength reduction above.
