Folks great info, I learnt a lot, though my original question got lost
somewhere in the math :-) thanks to all who contributed to the discussion.

The original question was more to do with interference caused by a nearby Tx
antenna used by another radio operator (not a ham) getting to my audio
equipment which is connected to my TxRx. My own equipment is near quiet as I
have proven when the neighbour was not operating. I suspect that my mains is
picking up the Tx from next door, I was thinking of a mains filter, what
type, who makes them (240V-50Hz)

Now another question. Any thoughts or comments/data on Protective Multiple
Earthing systems and interference or use near/in radio installations?

Also anyone ever had a electricity supply board timer (used to change for
daytime high rate to evening/night time low rate) cause interference to
radio or telephone circuits by introducing a click, click, click steady
repeated sound?
