On this, I agree completely with Phil.

The problem stems more and more from computer consumers who willy nilly 
download some software and just because they can get the other side to 
print what they type by clicking on some icons on the computer display, 
assume that everything is under control (as in "the control op knows 
what he is doing").

I have attempted to explain it for the Mac community with a 
documentation that can be found at

http://homepage.mac.com/chen/cocoaModem/Documentation/main.html

In Appendix A (after Section 8) there is a discussion of RTTY and in 
Section A.4 of the Appendix is a section on "Where am I transmitting?"

(I should have said "Where does Riley Hollingswood think I am 
transmitting?" but this doc is intended for an international audience, 
HI)

Not that I have any illusion that this application's users will bother 
to read it.  I have considered putting it in a splash window like when 
you have to agree to a software license, but I figure nobody reads 
_that_ either.  Mac users are just as apt at not RTFM as Windows users 
are.

That said, I think PSK31 PacketCluster spots are way more broken than 
RTTY spots.
