Imagine a telegraph office where all of the operators are hyped up
on speed enhancing medications.
The sound of those signals is definitely not synchronous in nature
as there is no constant rhythm to them, pretty well negating the
sense of a "teletypic" mechanical rhythm.
Had I the time I would record them and reduce the playback speed by
a factor of five or six. I think it would become rather obvious that
they are CW via FSK.
The shift is definitely 850 cycles.
I ran the Steppir into the dipole mode and swung the beam around
looking for a peak and a null. My indicator shows them to be either
northwesterly or southeasterly from this corner of the U.S.
The strength varies form S-9 plus five to deep fades to S-3/S-4,
indicating some distance away.
It's a pretty hefty transmitter, probably at least ten or twenty
kilowatts.
