[RTTY] Latest craze in contest exchanges?

[Ekki Plicht]

During the recent WPX (as op at LX8M) I noticed a lot of stations, mostly from 
eastern and southern EU who started their transmission with three or four 
dots. Like

... LX8M de <callsign> <callsign>
... LX8M UR 599 001 001

and so on.

Has there been an article I missed which said that this is the best remedy 
against whatever problem or what?

Ok, I know that some TU are slow to sync on a signal, I start all my 
transmission with a <space><CR> sequence. But why dots? And why so many?


Curious,
