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.

Hi Ria,
we had several requests, including some from members of band planning
committees, that we should choose a spot below 7050 on 40m, this based
on that being the upper edge of any globally coordinated narrow band
digital section. It was also pointed out that region three has an EMCOMM
frequency at 7050 so with hindsight 7047 is not that good. Region 1 has
digital modes up to 2700 Hz bandwidth including automatic stations
between 7050 and 7053 and more automatic unattended <= 2700 Hz bandwidth
allocation between 7053 and 7060 where the digital modes section ends.
Region 2 is similar except 7060 is another EMCOMM QRG.
Given that 7047 does not look so low as far as I can see. I missed that
there was a W1AW code practice broadcast on 7074.5, which was
unfortunate, but it looks to me that further down towards 7040 is the
only way to go unless there are better options up in the all modes
sections above 7060?
Thanks in advance for any helpful input you can provide, we do have the
advantage that in general everyone using a WSJT-X mode on HF tend to
stick very close together and move as a pack. So changes are possible
and we really want to find the least contentious spot.
