Hi Brian, Every journey/task begins with a single step.
It would begin with a study of watering holes (dial frequencies) on each band, with two concentrations. First, those that are causing QRM to other users of the bands during contests, moving all activity above .070. Second, reducing the spacing between dial frequencies to 5 kHz, allowing the suggested use of rigs with wider IFs to use that much spectrum.
160M is an example of excellent allocation of multiple digital modes that are appropriate for that band.
The process requires the participation of active users both analog and digital modes on the bands in question, and in different parts of the world.
On 6M, with NA allocations, there's no good reason for digital operations to start higher than 50.25, and to be spaced more widely than 5 kHz. With Es, TE, EME, and occasional F2 openings, choices need to work worldwide. BUT -- contesting, DXing, grid chasing are the operations that need relatively tightly packed operating frequencies so that they can be monitored on spectral displays (the factor that killed CW on 6M when 50.313 was chosen for FT8).
I suggest beginning with moving FT4 out of the CW portion of the 40M band, and understanding that the needed spectrum is 3 kHz.

How would you propose that these issues are addressed now Jim? I'm in no way knowledgeable enough to know where to start but the thing that comes out from what you've said is the sheer complexity and timescale for getting changes made, perhaps the problem now is that the horse has bolted and that catching it and returning it to the stable is going to be a difficult job. There may be more than one horse.
