[Elecraft] Kx3, wsjtx, broadband noise

[Jim Rhodes]

Well, it sounds like it is something outside your QTH. Unless you have some
solar charge controllers for off grid power, or some other possible noise
maker. Maybe go mobile in the neighborhood when the noise seems to be on
for a while. If you have a directional antenna you might be able to get a
vector that way.
