[Spooks] Arecibo Observatory ionospheric heating signal or XM Whales?

[Curt Rowlett]

I recorded this <https://youtu.be/8L6lV4IReCk> while monitoring 5125 kHz,
the known frequency for the Arecibo Observatory ionospheric heating signal.
However, after I posted the video on my YouTube channel, a comment was
posted by a person who informed me that the Arecibo campaign was only
active during the period of July 24th through July 31st. (I recorded this
last night. The time and date can be seen in the UTC widget running at the
top right of the screen). The person who supplied that information believes
that this signal actually might be XM Whales transmitting on the Arecibo
frequency.

Here is a link to the video <https://youtu.be/8L6lV4IReCk> that I recorded.

Anyone have any thoughts on this?
