I've been hearing (and seeing on the P3) an 850 Hz shift RTTY signal on 10.130 MHz for years now, virtually every evening. I use it as a propagation indicator on 30m, when it's strong I can work into the eastern US from here (NM) easily. I've read that it is an encrypted transmission of the US Navy, possibly from the Cutler ME NCS.
I see that it turns up on this list: http://ik4hdq.net/doc/10to30MHz.htm But this signal I observe has an occupied BW of no more than 4 kHz. It's certainly not spread out over a 14 kHz bandwidth you indicate. Maybe you are seeing something else? Does it look like wide shift RTTY?
