I made the experiment over AWGN and ROS is 2 dBs better than OLIVIA 32/1000. But we are comparing two modes at differents character rate. As you know ROS is two times faster than OLIVIA 32/1000. You should compare ROS 16 with OLIVIA 8/1000.  Then the different is about 5-6 dBs for the same char

If the radio has RTTY as a mode, as does the TS-940 for example, it means (1) there is an input on the back where you put in a baseband signal and FSK comes out the antenna, and (2) for receiving it will use a narrow filter and center the filter up around 2.2 KHz. (By "baseband" I mean the actual
