interference source

hi to all just thought id share this with you all .Ive just managed to find the biggest cause of my static on 11m after nearly 18 months of 10db wall of noise it started in the winter at 4.30 pm and went off around 10.00 am then in the summer came on later went off earlier some one suggested street lights but it wasnt street lights it was a bathroom light from three houses away it was a chinese led oblong shaped one with its own psu ! i had a chat with my neighbour and to my surprise he said he'd bin it and use something else what a guy. Ok i still get static but not as bad so radio is good at the moment all i can say is maybe if you have sourced your noise problem post it on here you never know it may help a fellow member to find their problem 73's to all Mark
