[RTTY] Dash vs space, more beat this to death

[Andreas Rehberg]

ok, so for the guys hunting for milliseconds a solution could be
to have 2 sets of exchanges available.. one additional for the
strong stations returning - with USOS temporarily switched off..

on the usual exchange that should save 7 characters (4 spaces
= 4xLTRS + 3xFGS) per 167ms are 1.17 sec. 
(pse correct me if I calculate that wrong)

that sounds much.. per 1,000 QSOs that's abt 20 minutes..
at a rate of 40 Q/hr that are 13 additional QSOs, well
that sounds not so much.. (at least it is emvironmentally
friendly)
