Yes to a certain extent.

There is no even/odd, Tx vs. Rx is randomized to ensure every station has a chance of receiving every other in some period. Stations may choose to be more beacon than spotter by adjusting their Tx percentage. > > Does the current logic do that? The current logic globally coordinates all band hopping stations to the same bands with the option that each station may lock out some of the bands dependant on the time of day because of its propagation influence i.e. there's no point transmitting on LF in daylight hours but it is essential around the terminator due to grey line enhancements. It also randomizes Tx periods except that the random schedule is adjusted to avoid multiple consecutive Tx periods. > > > 73 > Mike W9MDB 73 Bill G4WJS.
