[RFI] treadmill noise

[Jim Brown]

Thanks, Lionel. The key to making a filter like the Delta or Corcom is 
to mount it so that the chassis of the filter bonds to the chassis of 
the noise source. It sounds like that's what you did.

Question: You said "common mode line chokes"  -- exactly what were those 
chokes, and what frequency were you trying to kill?  What core material, 
how many turns through each core?
