Can it? I see little evidence of that. The second-pass decodes appear in
the Band Activity window after the first-pass decodes and my experience
are relatively few in number. And when FT8 was first introduced, Joe
Taylor said that two-pass decoding would not be as good for FT8 as it
was for JT65.

The ability to decode overlapping signals should be seen as a bonus, not
something that should be used as an excuse to transmit overlapping
signals intentionally, let alone used as an excuse to try and squeeze a
quart into a pint pot in band planning.

FT8 needs to spread out. Trying to cram everything into a single SSB
channel is ruining it.
