Although this is a clear requirement for QRSS qsos in order that everyone can have a fair chance within defined segments for QRSS operation, if the discussed other data modes allow much faster qso times then it should not be a requirement for them. If the qso time can be reduced to 15 minutes or less (as I sure these modes will allow) then operators can time share and all have qsos in sequence. In any case, unless qso times are reduced to these lengths qsos will remain rare as they will be unable to take advantage of relatively short openings. 73s Dave G3YMC dsergeant@btinternet.com dsergeant@iee.org http://www.btinternet.com/~dsergeant
