Guess you missed the point.  Andy's work was with the K3 which he no 
doubt owns and likes.  FLdigi no doubt has facilities to do testing for 
their software and I have major doubts that their are thousands of folks 
running AFSK RTTY on anything in any case.

The major thing is that the K3 Folks like FlDigi and others are willing 
to make changes.  Doubt that Icom, Yaesu, Kenwood are listening much in 
the RTTY reflector.  A lot of folks choose the K3 just because they 
listen and are willing to make changes.

The RTTY community should appreciate those folks who are testing and 
enhancing our mode of operation.  Folks like Andy, Chen, David have done 
more in the last couple of years for RTTY than a lot that went on 
before.  Us old pharts that are in love with narrow filters, FSK, are 
starting to learn that the soundcard has some major advantages heck I 
might even have to retire my Hal ST-8000 and my old trusty FT-1000D.  I 
can feel a K3 and a fancy soundcard in my future.  Maybe even a fancy 
interface tho I have to retire these opto's.
