*The WSJT-X Development Group selected the FT8 frequencies now being used
by all. I believe that after serious consideration, they should define a
recommended DXpedition mode frequencies for each HF band. I'd further
recommend that the 'Frequencies' table be populated with these recommended
DXpedition mode frequencies. Even better, whenever the 'Fox' box is
checked, display ONLY the recommended DXpedition mode frequencies' in the
band pull down menu.*
Very constructive, Rich. I would add that if a real DXp freq plan can be
"generated", it needs to be *enforced in the software* , not just be in an
easily manipulated frequency table.
If, after due consideration of the needs of all the digital modes, a plan
can be implemented, then the place to do it is *inside *the software. Hard
code the mode/freq. If left up to users, DXp will be done wherever anyone
chooses. The choice cannot be left up to DXpeditions....that's what started
this conversation in the first place.
