Hi all,

Let me assure you that we are very much aware of possible issues with 
the initial, suggested, and expressly provisional FT4 frequency for 40 

We (the WSJT developers) do not choose these frequencies unilaterally. 
Rather, we consult widely, ask for public input, eventually make a 
suggestion, and then change (if necessary) when/if a different consensus 

FT4 was openly released less than a month ago.  Initial FT4 default 
frequencies clearly labeled as "provisional".

The following published documents that list the IARU recommended band 
plans for Regions 1, 2, and 3:




To summarize: The above documents recommend 40 m frequencies for CW and 
narrow-band digi-modes (NB DM) in IARU Regions 1, 2, and 3 as follows:

Region    CW        NB DM
    1   7000-7040  7040-7050
    2   7000-7040  7040-7050
    3   7000-7030  7030-7060

It's clear that these band plans were not developed with the
possibility of explosive growth of digital communications in mind.  This 
problem is particularly apparent on 40 meters.

Hopefully the IARU, ARRL, and other relevant organizations will 
recognize the weakness of the the current band plans and start to do 
something about it.  And perhaps an interim solution can be agreed to 
while future band plans are being developed.

We're doing our best to be compliant with world-wide needs and to 
respond to wishes of the amateur community.

It doesn't help to complain here.  Much more effective to give relevant 
band-planning committees your thoughtful input.
