[ARRL-OK] RTTY Signal near 10132 kHz?

[Kim Elmore]

Curiosity has gotten the better of me and after all this time I have to 
ask: Does anyone know what the RTTY signal around 10132 kHz is?  I've tried 
all sorts of ways to decode it with no success.  I don't expect it to 
necessarily make sense (it's almost certainly encrypted), but I haven't 
found any combination that acts as if I'm decoding the characters properly. 
It's 850 Hz shift and so probably government/military.  It's quite strong 
and so probably originating in NA, ands it's there every night and quite 
possibly 24/7.

What is it?
