[Elecraft] HF noise.....10 M

[Rick Bates]

A digitally controlled motor can do that.  Think dishwasher, washing machine...

Mine does it but I can tell when a neighbor does chores too.

They sound like a very unstable oscillator, almost like there's a random (or encoded ?) narrow frequency modulation as they move lower down the band.  They are quite noticeable on the panadapter display and appear to have several rates of downward frequency shift.  Also, occasionally, a wide band "hump" for lack of a better word. will appear in the display and pop off a second later as quickly as it came.  I've tried tracking them down, but they all seem to not be coming from anything in close proximity to me.

It's just that this is the first time I've been able to "see" them on the screen.  The display kinda reminds of the Quark capture displays we used to see.
