I did not get a chance to look at this signal closely, however, at first glance it was 850 Hz shift FSK. It appeared to have only two tones of actual data, however 5 or 6 tones were seen, making it very wide. Each of the tones appeared to be a duplicate of one or the other of the two tones with unique data.
Total guess here, but it looked like a distorted STANAG 4481 FSK signal. I would guess a spur or broken transmitter.
Unfortunately, I did not make any recordings of the signal, literally every receiver and PC here at the desk was tied up making other recordings at the time.
T!
