I see it as a good test of the FT8 decoder's ability to pull out the
data from all the dross.

I'm curious where these ranges came from. The 10/15/20 meter ranges
look like a good idea, but it seems like 3.590-3.600MHz and
7.080-7.100MHz are recipes for a lot of FT8 frustration.
Both of those ranges are normally amongst the busiest RTTY contest
sub-bands, especially in contests that have a large domestic component
(like the RTTY Roundup).
I suspect there will be a lot of RTTY ops unaware of this
recommendation firing up in those ranges not realizing that there are
FT8 QSOs hiding in the noise.
I fear that these recommendations will result in a lot of unsuccessful
FT8 QSOs, which are no fun. Better to find a lighter used range where
FT8 ops can find each other and have more fun.
It would seem to be much better to use the top of 40 as was done for
the higher bands - data can go up to 7.125 - so why not choose
7..115-7.125.
And on 80, RTTY stations tend to bunch up against the 3.600 limit.
Better to locate FT8 down at 3.560-3.570 or even 3.550-3.560.
I suppose that at this late date there's no changing this. I would
recommend to anyone having difficulty on the recommended frequencies
to go up higher on 40, and go lower on 80. You'll find more room.
(And just FYI, some of the RTTY ranges shown in the table are not
accurate for big contests that have both domestic and DX. On 40 you
will see RTTY from 7.030 all the way past 7.100. On 80, you will see
Asian DX down around 3.525.)
