Not to be argumentative here…
So I send the exchange twice. One gets wiped out by the “static crash”. What
do you do? Now you’ve only seen the exchange once. Do you ask for a repeat?
Contesting is a set of decisions, done real time. If I’m running and I get
more than the usual number of repeat requests, I’ll likely start sending the
exchange twice for a while. Band conditions change. QRM changes.
I operate RTTY the same way I operate CW. There is really little difference
other than the way the “data” is decoded. The human decoder has some
advantages, to be sure. But using multiple decoder windows can make up for some
of the deficiencies in RTTY decoding.
The “extra few seconds” can be a factor. Make 2000 Qs in 24 hours (average
83/hour). 2 seconds per Q is about 60 minutes. So it could mean 80 – 100 more
Qs. That’s a 5% increase. Significant, I would say.

You have to believe that the receiving station is not hearing you great such
as what David describes. I mean, it's common sense, what on earth is an
extra
couple seconds going to make. I agree with David, always send it twice as
there are so many reason's why just once may not be heard.
