As I understand it, hams had to get permission from the FCC to use
FSK.  They originally tried it with on-off keying, like CW, but it
didn't work very well.

   There was a story in QST within the past 18 months about a ham who 
"invented" 
   the walkie talkie.  He also developed a system to transmit teletype signals 
   over radio.  He invented a lot of other things, too.  I am sorry I can't 
   remember his name or call.  I do recall that his picture was shown along 
with the 
   QST story.  Radio-teletype was not developed for amateur use.  Later, 
amateurs 
   (once the FCC okayed FSK transmission) adapted the FSK techniques.  

   Others have correctly written that the first amateur uses of FSK involved 
850 
   Hz shift.  

   If anyone has access to the December QST issues of recent years, he might 
   look in the index and find the article.   It's worth reading and I wish I 
had 
   saved it.
