[RTTY] CQWW Time Period

[Julian cleak]

Hi all,

     Does anybody know what the time period is for working mults in
multi single now that the 10 minute rule has been changed to 
6 band changes per hour. 

Does it mean that if the run station is on 15m and a mult is worked on 20m
that a new mult can't be worked on say 10m until the run station changes
to a different band.

or

Does it mean that if the run station is on 15m the mult station can make
6 band changes per hour to work other mults.

                                    Thanks

                                     Julian ( GW4JBQ )
