[CQ-Contest] Contesters review: new FT8, WSJT 2.0.0

Ed, in one of the single-hour "contest mode trials" of WSJT 2.0 release
candidates, I hit 36 FT8 Q's in an hour. The abbreviated contest exchange
and the fact that most of the guys on had some contest-leanings, really
helped me in that hour.

I did that by going almnost 100% S&P where I get the one-per-minute cycle
time. It also really helped, that the trial hour band segment was not
completely jam-packed with signals.

In the big FT8 test weekend two weeks ago, I did not hit that rate. Even
when I focused and tried hard, I was usually only in the 20's for rate over
a while hour. I attribute this to many of the participants being less

The 120-per-hour run rate with the "TU, NOW" feature you mention, I think
you might be able to exploit that from P4, with callers spreading
themselves nicely and being patient to work a rare mult, but my feeling is
that us more common mults will hardly ever use that.

Again, I do not plan to do any FT8 during RTTY RU. However, I do appreciate
that the WSJT developers are learning some things about contesting to
improve rates and that non-contest FT8 rates have improved noticeably as a
result of this learning.

Ed, what rates were you able to hit in the FT8 weekend two weeks ago? I
think when the logs are collected that AA5AU may be able to advise us as to
peak rates hit by participants.

I did a quick-looksee at 3830 comments for FT8 roundup and see two
experienced contesters talking about a best hour of 38Q's, and more typical
"good hour" rates in the 20-30Q per hour range.
