[CQ-Contest] 40m "new" approach to staying in the band?

[Zack Widup]

I don't quite get the complaint about 14150.5. Is it that MOST of the RF is
in the band but the suppressed sideband may yet still be there? If you could
be guaranteed of only a USB signal being there, it would not be illegal to
use this frequency on USB. I listened to several SSB signals on 20m and
switched to the LSB position and couldn't hear a thing. So I assume they
were suppressed below the minimum requirements. That's easy to do with
today's rigs.
