Title: If Not RTTY...?
Post by: Erik Mattson on December 27, 2021, 2300 UTC

What is it that I'm hearing, on 7456 (usb?) at the moment (2255 UTC, 27 Dec 2012) that sounds like RTTY?
It lines up perfectly with RTTY>RTTY-75W settings in FLdigi but it doesn't decode, and doesn't have an encrypted look (for all I know).

Ah. STANAG.

It most certainly is RTTY. If you tune to 7455.300 kHz USB it is Mark: 1275, Shift: 850, Baud: 50.
