Hi all,

the debate about pro RST and contra RSQ (or vice versa) as far as RTTY
is concerned,  motivated me to consult 'The radio amateur's handbook'
35th edition 1958 chapter 24 page 580.

Some exerpts: T means (definitely) tone  

*** T 1 extremly rough hissing note ***
-
*** T 5 musically-modulated note ***
-
*** T 9 pure d.c. note ***

When i started ham radio as EP3HS (back in 1960) from Iran,  the C.W. of
(particulary) our neighbour-hams in the north of Iran seldom earned a T9 report 
and sometimes really did hurt our ears.

But, and thats a big 'but', they did everything to keep Ham-Radio going
under rather adverse circumstances and their  efforts 
still have my highest respect.

Footnote Page 580 (last sentence): "The above reporting system is used on both 
c.w. and voice, leaving out the "tone" report on voice".

My facit: Since human ears are very little  involved in decyphering digital sequences of tone,
(exept in c.w.)  
I personally find the term RSQ more appropriate,to express 
 - for instance - that the Signal is overmodulated (therefore splattering) etc.  

Not a very big issue, but it was rather interesting to read your opinions about it.
