In most contests, classes of operation are defined by the number of 
operators and the number of simultaneously transmitted signals. Most 
SO2R operation entries are in the single0op single transmitted signal 
class -- that is, listening on one band while transmitting on the other. 
While SO2R results are reported separately on 3830 Scores, that's still 
a single op single transmitter entry.

I've entered at least one contest, Makrothen, that has single- and 
multi-receiver classes for single- and multi-op.
