Hi All

I have an question.
What is the first RTTY CONTEST? 

VOLTA said the 2005 is 39th time.

That is, probably, 1966 are the beginning. 

Key word of RTTY was discovered in P.14 
of "Historic Results 1967" of DARC.

These pages are really wonderful! 

What is the first RTTY CONTEST? 
Is that BARTG? SARTG? ANARTS? RCJ?
