Hi Jay,

It sounds like you need to install an EMI line filter between your
wall socket and your power supply xfmr. This will attenuate the
RFs that feed back into your house wiring and into any other ap-
pliance that happens to be plugged into the same circuit. Install 
it into your 240 volt/20 amp input and make sure the EMI line fil-
ter has an adequate voltage/current rating to handle the power
that you are processing. Don't count on the filter to completely
eliminate the RF feedbacks, though, as you may still notice some
interference on TVs, radios, ect. while running your coil. It should
improve the situation, though.

Also, make sure that you have a very robust RF ground like (3) 8 ft
long copper-clad ground rods driven into the ground all but ~6" and
interconnect them with buried copper strap or bare braided welding
cable. Hook the base of the secondary to the RF ground via a heavy
guage welding cable that is as short as possible.

EMI filters are generally available at surplus houses like C&H Sales,
Surplus Sales of Nebraska, ect. Hope this helps you out and you
are getting excellent results with your coil :-) BTW, you can paral-
lel 2 or more EMI filters together to achieve the required current rating
of your system if you can't find/afford a single filter that's large enough.
