[WriteLog] What's wrong with AFSK? was - 5 bit mystery unraveled

[Jim Smith]

It seems to me that the cognoscenti prefer FSK to AFSK.  I have never 
seen any reasons for this preference, probably because I haven't looked 
in the right place.  So, what's the problem with just sending AFSK to 
the radio, thereby eliminating the need for an AFSK to FSK converter?
