> I observed Russian Radio Team Contest as preparation for WRTC-2010. It was held just outside Moscow with 18 two-man teams, and was the 18th straight year that it has been held. Field Day style, all stations within a few miles of each other (but minimum separation of 500 metres) on flat grass-lands. Identical antennas: tribander and 40m Vee at 35 feet. Eight-hour multi-mode contest, changing call-sign and exchange each two hours. Full-time Referee monitoring each Team. The winner RW3QC/RN3QO made 1,532 QSOs, an average of over 190 per hour throughout.

All the leading four teams used a filtering system allowing TX on one radio and RX on the other radio at the same time ***on the same antenna/coax***. Cor!
