[CQ-Contest] Many US stns out of band

[Barry W2UP]

I'm not a SSB op, but got on to work a few stations in the contest.  I
heard a number of DX stns CQing below 21200 and USA stations were calling
them.

>From what I can find online, the US phone band starts at 21.200.  Is this
correct?
If so, does the log checking software disallow the QSOs that took place out
of band?  If so, for one or both sides of the QSO?
