An offshoot of ham RTTY activity to note is the development of the deaf 
TTY (or TDD) system.

Way back when I was in high school and had recently gotten my ham 
license I got interested in RTTY.  I subscribed to the RTTY Journal for 
a few years.  One of the authors that I recall seeing on those pages was 
Robert Weitbrecht, W6NRM.  Later I learned that he had developed the 
acoustic coupler modem ("Weitbrecht modem") used for the TTY.   For 
anyone interested in the history there is a book, "A Phone of Our Own". 
(I haven't read it yet.)

73,
Gary
