You are indeed a lucky man.
Man made noise is something that should receive a much higher level of
official protection.
Switched mode PSU's, computers and games consoles are something I hate ;-)
However perhaps we can now use the new EMC Protection directive 2004/108/EC
which came into force 6 days ago to help protect our hobby from noise
(grr).

Tyte QRM eliminator circuit that I sent out is fine but it must be
remembered that it is only capable of removing *1* source of interference
at a time. All other QRM sources will be arriving at different amplitudes
and phase - meaning you have to choose which QRM you want to eliminate ;-)
Of course if you only have 1 QRM source then everyting is OK.
Or the alternative is to go /M or /P like I do much of the time (see my
G0FTD-P.JPG files).
