[RFI] treadmill noise

[David Robbins]

When turning on for the 160m contest I had strong stable noise spikes every
15khz across 160m.  Checked everything in the house then went for a walk
with my grundig g5.  It was much stronger at the power pole so picked left
and started up the road that way. it slowly got stronger as I approached the
next house about 1000' up the road and was much stronger at their pole.  The
couple was home so I went and let him hear the noise and asked if they got
anything new recently, nothing. then asked if anything was running that
wasn't on all the time, she was on their treadmill.. Shut it off, noise
gone.   The treadmill is a ProForm ProTech 3.  Anyone have a good line
filter for a treadmill??
