[sdiy] Shielding - (Was: 100 MHz EMI, what can it be?)

Well... you could surround the room with Mu-metal... or just give
the magnetic flux a good alternate path bu making the room entirely
of some nice, thick soft steel. Maybe 12ga would be good...

I think you can get Ferrite tiles to pave the walls with... that would work well for RF frequencies...

I'd suggest just refurbishing or discarding any equipment that does not pass RFI/EMI noise standards...

(half of the consumer / low end studio gear is probably responsible for the noise generation and/or pickup anyway. I have an old Tascam mixer that doubles as a radio receiver....)
