It sounds like you have the RF feedback into the mains suppressed, so I
am thinking that the interference is due to radiation from your coil. One
thing you might try is to place your spark gap inside a grounded metal sheild.
This may at least help you determine whether or not the gap is the culprit.
An EE buddy of mine keeps insisting that I place my gap in such a shield to
prevent the emanation of x-rays (and VHF/UHF radiation perhaps) from the gap
itself. I plan to do this once I am satisfied that no more adjustments need
to be made. It would be worth a try anyway. It would certainly be easier,
if it works, than screening in your whole garage as a Faraday cage.
I am surprised that none of my neighbors have ever complained about my
coil. I run my coil from two 15/60 neons and I have taken no measures to
prevent feedback(aside from the RC filter circuit recently added for neon
protection) into the mains nor shielded my coil. I live in an apartment
with neighbors on both sides, yet I have had no complaints in the years I have
lived here :o) Call me lucky.
Hope you resolve this without too much trouble.
