[Spooks] Data bursts - beacon perhaps?

[Utility World (Hugh Stegman)]

Globe Wireless markers on 4459.0 from the Dixon site in north central
California.  I have it S9 right now in day time, so the radius is right.

Someone else reported a weird noise on 6431.4 which is also a Globe marker,
but it briefly had their odd failure mode where every burst drifts upward in
frequency with the characteristic little 170-Hz boink in the middle, then
goes back on-channel between bursts.  This is WNU in Louisiana and they'd
fixed it last night.
