[600MRG] HF-MF band planning

[Brian Pease]

My two cents:
CW gets it's own space, say the lower 1kHz. WSPR needs it's own 200Hz 
clear channel, and possibly JT9.  Other digital modes come and go.  
Otherwise I would group them by bandwidth, with JT9, Jason, etc in a 
narrow band/weak signal space with PSK31 and everything else broader in 
the large remaining space.  I don't know what the "dividing" BW should 
be, 10Hz?  What should the wide cutoff be, 100Hz?  The different chat 
modes can informally sort themselves out as they come and go over the years.

> John, thanks for the additional info.  Where have I heard these no-CW comments?  In emails, and in-person and on-the-air discussions.  If I were to summarize, there seemed to be two main reasons offered:  (1) Emergency communications is the reason for the new band and these networks need to use computerized below-the-noise demodulation modes and the should be protected against interference from "routine" amateur operations.  (2) There isn't enough room in a 7 kHz band for anything but machine-precision modes.  As you might expect I pushed back on these ideas, making the point that CW is good for emergency comms and there needs to be room for both modes.

But that is not usually what is meant when some people speak of "digital modes" - they are referring to DSP-generated waveforms from personal computers soundcards or specialized modems such as listed on http://wb8nut.com/digital/ .  So it is wise to be clear on that point.

For example, the IARU claims their bandplans are voluntary, but actively promote their bandplans as templates for future regulation.  That's why I care about bandplans and try to work toward fair and open plans that makes sense for as wide a variety of amateur operations as possible.
