BTW: Are these "always" USB ?

I'm sure someone will come up with an exception, but all SSB traffic
except for ham radio is USB. Many modern commercial radios don't even
have LSB as an option.

Ham radio is LSB on 160m, 80/75, and 40m, USB on all other bands. The
old saying LSB below 10mHz, USB above is no longer true, the 60m band
(U.S. only?) is USB only (no CW/LSB/AM/FM/digital).
