Thanks. I thought that was why you posted, but I have not seen a signal like that before. I would be interested in what it turns out to be once you locate it.

Hi Dave,

When I look at the video, it starts with lower resolution and then
clears up so I can read the frequency scale. Nevertheless, the scale
goes from 3920 kHz to 3995 kHz and the RFI sweeps about 30 kHz. By the
way, I am not seeking speculation as to what causes the RFI; I just
posted this to illustrate the value of an SDR with a panadapter over a
conventional receiver for tracking it down.
