Where are you getting the interference, is it on the Sky channel, the terrestrial channels, or all of them?

What are the channels from your main terrestrial transmitter and is there more than one?

Sorry, have read your post again and I think I have grasped it, what digibox are you using and is there interference on the Sky channel as well as the analogue channels? It may well be that you are putting too much signal into the digibox, also, do you have the voltage turned on at outlet 2, but no remote eye?

If you know your transmitter and all the rf outlets for all your boxes use this site:

to work out the "safe" rf channels.

Don't think that is so much the problem Analoguesat, I took a second look and thought that perhaps the interference is on the terrestrial channels, so more likely to be a signal overload.

Oh well, it was a good idea.

(Ive added the link the the Big Links section)

Nice link, but they don't seem to cope with contiguous transmitter areas, or if they do, it isn't obvious to me.

We dont have these problem up here in the wilds of south scotland. You get your local transmitter. End of story. Even in high pressure situations.......

Are u using an "ordinary" tv connector cable? Sat grade cable (foil sheath) will stop all external interference, then you know it's something else!

sorry guy for not replying to all your hepfull infomation i see this time and time again on this forum and think it is rude so im sorry the the problem was signal overload as i was using sky gade cable sreened outlet the distance from the dish to the receiver was about two meters i moved the dish not its position just the angle so it was slightly out of alingement and it fixed the problem .i dont now how the experts get round this problem but it seemed to have worked once again sorry for not replying sooner it wont happen again
