Joe,
Greeting from nice weather weekend just before rainy season here in Japan.
I am fine with your comment if you "WSJT developer team" has already
being working for next generation format, such as sensitivity and fading
performance of FT8 (15 Second format) to be compatible with WSPR (one
minutes format).
Regards,
take

Hi Jim, K9YC:
You write here of "major errors," "massive failures," "developers
living in their own world," "failing to consult with other users of
the spectrum," etc., etc.
You write: "The major error that developers made way back when, and
CONTINUE to make, is to chew up way too much spectrum by spacing
watering holes with excessive spacing, and by... "
We (developers of the digital protocols in WSJT and its sister
programs) have never dictated any band usage plans or unilaterally set
any rules for particular frequencies. On the contrary, we've always
emphasized that such plans must be community decisions. We have sought
wide input before making even tentative recommendations for a dial
frequency for exercising a potential new mode. I could be wrong, but I
don't recall that you ever responded to any of these requests for
input, when we made them.
Chewing up "way too much spectrum" ??? The 3 kHz slices of spectrum
used for most FT8 and FT4 activity on the HF bands are on the order of
one percent of our allocated spectrum on most HF bands. WSPR uses an
order of magnitude less still. The consensus "way back when" was that
something like 10 kHz spacing between (say) initially recommended 3
kHz slices for FT8 and FT4 made good sense because usage patterns
suggested increased future occupancy and a likely need for the
conventional sub-bands to grow somewhat.
Suggestions for better band plans could be useful. Why not produce
some, rather than issuing broadside complaints with the implications
that you would have done it better?
