Topband: Line noise

[Manyoaks]

I have a similar problem - and in my case it is caused by low voltage
(halogen bulb) lights - or more precisely the switching power supplies that
transform from 240 V to 12 V.  It is S9 on 80m and wipes everything down to
BC bands.  I traced mine with a ferrite rodded antenna in a portable AM
broadcast radio - that gave me the directional info I needed.  However the
wiring of the house radiates pretty well once the noise is in the system!

The only solution was to replace the switchers with regular ferrite cored
transformers.
