There is no rule prohibiting “duelling CQ”, i.e. running on two bands simultaneously. This is OK with the rules as long as only one signal is transmitted at any time. I have checked this personally with the CQ contest promotor a few years ago before adopting this way of operation. 

To me this is useful even at low rates at the end of the contest as calling CQ on two bands are more likely to increase the rate than working just one band.

In addition N1MM is set do this with an additional SO2R controller and two radios.

73 de Björn,
