Others have mentioned null steerers that you can buy and are very effective. If you would rather build one for yourself, see the latest SPRAT (best value for money radio mag - ever). On pages 6 & 7 of the latest issue 145 is shown a simple home-build unit called the Plasma Nuller from Pat GW0VMR whose neighbour's plasma tv wiped out his 80m band and nearly put him off air. Jim's ferrite cures are of course the best approach from an emc point of view (cure the source) but sometimes you can't or don't wish to approach a neighbour. This method is probably the cheapest.
