There IS one reason to generate the SSB signal as LSB - many crystal lattice
filters (including the one in the KSB2) have a steeper slope on the low
frequency side, so the LSB generation is better than USB generation. Yes,
the sideband CAN be inverted by the proper mixing scheme - the current state
of affairs -- it depends on which transceiver you are talking about.
