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!
