[Spooks] Return of the UNID beeper

[Curt Rowlett]

The UNID "One Beep, Two Beep <https://youtu.be/6pQOSnu4aTQ>" signal at 4508
kHz that I submitted to the list on December 8th has returned.

UTC time and date can be seen in the widget running at the top right of the
video screen. Note that the frequency has changed, but it is the same
signal, with variations to the "One Beep, Two Beep" first observed.

UNID "One Beep, Two Beeps" at 4500.75 kHz <https://youtu.be/AaTqkbcfV9w>
(Signal changed pattern)


Anyone have any idea what this might be?
