With rotten conditions and marginal antennas 38 per hour can be better then 0.

> 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.
