[Spooks] XM "Whales"

[Zack Widup]

I've been sitting here listening to the "Whales" station on 10512 kHz for a
while. At 0505Z there was a sudden change in the loping, wandering tones.
It suddenly went into a rapid pattern of uniform tone changes for a minute,
then went back to the slowly wandering tone changes

It's done it a couple more times of shorter duration just while I've been
typing this message.

Has anyone tried recording this station and playing it back at different
speeds, faster and slower?

There certainly are some mysterious things to be heard on shortwave!
