[RTTY] Take Two RTTY Exchange

[Jeff Blaine]

The optimal number of repeats is situational.  Give you a couple of 
examples...

If you are S&P, you may want to consider a couple; and if you are running, 
then a single may be fine.  Because as a runner, you are sending the state 
frequently and there is a good chance that the S&P side of the Q may see 
your exchange from the prior and have that as a confrimation.

If you are running QRP, have a lousy antenna or some other weak source 
signal condition - you will be doing a lot of repeats compared to a guy 
running a stack and power.

QRN is a factory - lower band operation, especially in the summer, is going 
to result in more band noise prompting for more repeats.

There are other factors, but I would have to be with Bill on this one - two 
is a good number generally speaking.  I run 2 "KS" in my S&P, and unless the 
band is in exceptional shape, two "KS" in run mode as well.

I don't think the rx stn would ask for a repeat if he got a valid
(but garbled) exchange. And no way for the tx stn to know he missed it.
