[RTTY] Take Two RTTY Exchange

[Bill Turner]

We are starting to beat a dead horse here, so let me make this short and 
then I'll shut up (probably).

If Ed sends 599 CA and it gets garbled so it prints 599 CO, the other 
guy sees it's a valid state name and will copy it correctly but the 
information is wrong.

There is no way that either Ed or the receiving station can know it is 
wrong, but only the receiving station will get dinged by the log 
checker. Ed will not. Some folks will just say "too bad" and move on.

I can't do that. Contesters are my friends and I want their log to be as 
accurate as mine. Because of that, I send CA twice. I'm not a 
mathematician but I know that increases his chances of copying correctly 
a lot more than just two times. More like ten times, possibly more. The 
chances of exactly the same bit error making an A into an O two times in 
a row are very small. Maybe our friend Chen, W7AY could provide a more 
rigorous mathematical analysis?
