[CQ-Contest] 40M FT4 Frequency

A few observations, now that I'm sure I have plain text turned on and having
watched today's discussion with interest:

1) Above 7100 is hard because of how the narrower 40 meter band is used in
ITU Regions 1 and 3.
2) This is a hard issue, and may have no easy solution. 
3) It would be good to see ARRL pay more attention to this than to, for
example, whether Connecticut law permits Vice Directors. (Free advice from a
Connecticut lawyer: it does.)
4) From a spectrum management an defense perspective, this a very good
problem to have.

Not sure what the ARRL directors can do, other than suggest a different freq
(I think above 7.100 would be great). I think the software developers,
users, and contest organizers would be the ones to suggest "the move"
