[CQ-Contest] 40m lower band edge SSB

Just to put a fine point on it,  7125 is the band edge.  The FCC regs don't
say "Don't go within 3 KHz of the band edge", but of course, technically,
that makes perfect sense.  There are obvious violations outside of this,
but band-edge violations by mode are probably not something people are
going to take a coronary about it.  It is best to avoid them. (CW is a
different story).

I presume the log checking software uses the actual band edge, and does not
compensate for LSB/USB.

Probably most violations occur in the excitement of picking a packet spot
which is a new multiplier pops up.  One fix is for the contest software
to prevent picking out-of-band spots for your country or region.
