[CQ-Contest] What is "one radio"?

[K3ZJ David Siddall]

Sebastian,

You don't mention which contest you are asking about, but the classic
overlay category originated with CQWW.  In that contest (and all other CQ
contests with a classic category) the rules specifically state that
"receiving while transmitting is prohibited."  So no SO2R is permitted,
whether one is using a Flex-6700 (which has SO2R capability within a single
box) or two interconnected transceivers.

73, Dave K3ZJ


 Receiving while transmitting is prohibited. Single Operator Assisted
entries are not eligible for this category.
