Hi:
As a ham, and former RTTY operator, the _sound_ of RYRYRYRY... at 45 baud
was quite distinctive, and could easily be discerned by ear, for tuning
purposes. I operated 45 baud (Baudot 5-level code, not ASCII) on HF for a
number of years in the 70s and 80s. Built my own RTTY modem too, wrote my
own software. It was quite advanced, in that I supported 110 bps ASCII,
quite leading edge at the time.
