[RTTY] RTTY Screwed by FCC?

[Joe Subich, W4TV]

Tony, 

If you want to split hairs, no signal that is transmitted by RF 
(or light in fiber optics) is truly "digital."  Electromagnetic 
signals are analog media.  However, RTTY and CW certainly belong 
to the family of digital modulations (on/off, mark/space, phase 
reversal/no phase reversal, etc.).  The coding format used is 
immaterial - if the carrier can take only one of two states the 
emission is considered a "digital" signal (this also applies to 
each carrier in multiple carrier systems like MFSK, COFDM, etc.).  

CW and RTTY are most certainly digital modes.

73, 

   ... Joe, W4TV
