Anyone else receiving this? In AM, sounds like a low breathy note
on a flute. In sideband, sounds like a sweeping chirp - once per
second. I'm suspicious, because I can hear it about S3 during the
day, so I'm thinking local. (Perhaps my gas or electric company's
remote read digital meters?)


got the same thing here.
S9+
NE Wisconsin

Thanks. That rules out local.


Back to topic: There's another noisy note from 4.877-4.902. Over S5 at
19:48Z

Weak one from 4.916-4.936. S1 @ 19:58Z

Big one from 4.963-4.995. S5+ @ 20:00Z

WWV is S1 on 5mHz this time of day.

4.734-4.766. S3 @ 20:04Z

Two of them overlap 4.530 S6 @20:06Z

The first one mentioned at 4.810 is an overlap of two, as well. S6 @
20:06Z


I hear it continuously from 4734 right up to 4998~4999 where the splatter
from wwv knocks it out. I hear nothing at all above 5000 though. most of
it is just the one side - "weep". right at 4810 I hear both sides -"weep,
weep". real strong, with near full quieting. it's always there, but the
signal strength changes.

weird.

Kenwood R5000 to a PAR EF-SWL flat out north away from the house.


It's CODAR.
