Fwd: Re: [MilCom] Orderwire?

[Steve Douglass]

I've now been monitoring this mystery signal for almost 3 days now. 
It seems to by cyclic, moving first up in frequency then down in 
frequency over a range of six hours.  One monitor suggested it was 
from a HAMSAT, but I can't find any frequencies listed anywhere near 
the center frequency which now seems to be 229.560 MHz.

Another suggested it might be an image or a harmonic from a signal 
out of band, but since I've had various confirmations now from many 
sources spread out all over the Texas/Oklahoma/New Mexico area I 
think it's actual.

No voice or data traffic has been heard in the last 12 hours, but the 
carrier remains strong. As I right this it is centered on 229.6048 
MHz.  This is pure speculation but in may be a SATCOM channel, UFO 
(no not a flying saucer but the UHF Follow On Satellite) that is near 
geo-stationary orbit but must have some slight movement to due to 
what I perceive is a Doppler shift in frequency.

Speculation welcome!
