Anyone have any idea what those "weeblies" are on ten meters? They
typically start high in frequency and flitter past the receiver then stop
abruptly. 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.
I've heard these weeblies for many years. They're not a QRM problem since
they're only in the passband for a second or so and occur at about 1 to 5
per minute. 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.

Does the CW signal show up on a particular schedule? Does it seem to
repeat its transmission a lot?
It would be interesting to hear a modern numbers station like this -
they've really become scarce these days since the rise of the internet.
