[Lowfer] curious signal

[Dale Rice]

Let me see if I can get it right this time.
I think I put the jpg in the right place.
Flame away if not legible.

This may be a bit off topic but these were seen with ARGO so maybe that
makes it OK.
These signals appear to be from KFI in Los Angeles.
Their carrier is 8.4 Hz high and doing strange things.
Does anybody know what is going on here? I would assume they are trying to
send this signal to someone a long ways off, but what and who?
