yesterday morning it was strong S-9 plus toward 40 deg from west central
Alabama. I could copy it from 13998.3 to 1403.6 and then it dis-appeared
and hasn't been back since. Hard to tell! 73's Cort K4WI

All,
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.
