[Elecraft] RFI on K3s

[Clay Autery]

That's what I figured... Now to locate which one of the 50+ that are
present in this house alone...

They actually appear all the way down into the 14MHz range...  Always
there.  Tonight they were relatively stable in location... drifting
slowly, and even changed directions once.  At other times, the cyclical
migration up or down the band is faster and sometimes random, switching
directions repetitively and without discernible (to me) pattern.

Off to read...  Hopefully it is not the power supply I use for the K3s/P3...


73,
