I sent a question about the 'bogey' signal over to some of the 
'numbers stations', SDR signal analysis, Mil-Comms monitoring type of 
groups, yesterday.

I got a reply from one of the groups. That group looked at the 
signal, and recorded it for 'examination, identification, & decoding' 
attempts.   The result that came back from   them said that this 
signal appeared to be 'a known Canadian Navy signal type and was in 
STANAG 4285 and appears like Thales 3000 modems'  No way to tell if 
this was a stationary transmitter or a 'mobile' (water or air).


If mobile, that might be why it might have been in different seeming 
locations.  Speculation was also it might have been on a patrol 
routing between NA and Greenland air space.
