[RFI] More on 160 M RFI - significance of hum bands

[Rob Atkinson]

Sounds to me like a plasma TV.  If you were closer you'd hear noise in
between the 22 kc spaced barfs.  When the picture changes, the highest
amplitude blobs change too, going away when the screen goes dark.  The
h.v. supplies in the set can be noisy too.  If it is part of a "media
center," connected to telephone and cable, those lines will radiate.
It's a RFI nightmare.
