Hi Ria,
Good to hear from you!

Hi Joe, Bill, Steve and team,
I'm getting feedback about the frequency choices for the initial FT4
rollout. There is conflict with users because it is so low down in the
band on 40 meters (7047). The QRP fox hunt (CW) guys are up in arms
because that's where they operate. Other hams have been complaining to
their ARRL officials (including me) about the QRM.
I love the FT/JT modes and think that what the WSJT development team
is doing is absolutely fantastic but I think some more thought has to
go into where we want these modes to live so we can have peaceful
coexistence on the bands.

Experience shows that it's impossible to select even 1% of a band --
say, a ~3 kHz slice in a 300 kHz band -- for a new purpose without
stepping on some toes. Experience also shows that nobody wants to help
with this important band-planning task. (Maybe something like a new
ARRL and/or IARU Committee?)
Finally, our experience shows that sometimes we have to try something,
see how it plays, and then (if necessary) try something else.
Our frequency choices are not arbitrary -- far from it. We're very
willing to make changes when a balanced assessment shows them desirable.
FT4 has been on 7047 kHz for all of 24 hours. Not much time, but enough
to make it clear that a better frequency should be found on 40 meters.
I hope those who experience QRM from FT8 or FT4 will keep in mind that
(by some measures) these modes account for something like 70% of ham
radio activity, world wide, while occupying something like 1-2% of our
allocated HF spectrum.
Please send us your suggestions for default frequencies for FT4 and/or
other WSJT-X modes, doing your best to find choices acceptable worldwide.
