Title: 6935-6950 @ 0200z UNID - UTE or ? 8/19/2013
Post by: Kilokat7 on August 19, 2013, 0236 UTC

Did anyone else catch this on their overnight recordings on 6940 at 0200z?  Extremely strong here:

Yes, same exactly signal here. S9+20.

While I cannot be 100% sure of what it is without an audio or I/Q file (and the signal is not making it to the west coast) I am reasonably confident that this is Link 11 CLEW.

You can see enough detail in Kilokat7's image to see the 605 Hz Doppler tone, the 14 DQPSK data tones, and the 2915 Hz Sync.

The other image, showing 2 mirrored streams, looks like the signal is in DSB (or possibly ISB) on 6942 kHz.

T!

Thanks Token.  I suppose we can rule out Doctor Benway playing with digital modes again then, as I heard Undercover Radio on the same frequency and same signal strength about 15 minutes prior to this UTE burst captured in my screen shot above.  Hmmm...
