[sdiy] Frustrating RF Interference

[harry bissell]

Ahhh I was not clear about this...

I added the bead INSIDE the mixer...from the point where the
wires entered the case, to where they are grounded on the bus PCB.

I did NOT get any result with the bead on the outside...
No, I can't do dB readings because I can't remove the bead now :^)

The interference in my case may have been from a carrier current
transmitter (wireless speakers ?)in the apartment building I was in. VERY
curious, VERY annoying...
