BTW, given a choice between LSB and USB, the military's preference is

USB was the commercial standard for the 50 years or so that I've been
in that business. Even with ISB (Independent SideBand) where each
sideband has different information, the "lower" sideband(s) are not
inverted relative to the "upper" sideband(s).
