That is actually a darn good suggestion, and does not deviate from what we can do today on FSK with the current regulations.

I.e., the narrowest 2 tone FSK bandwidth you can get by using the maximum symbol rate and FSK shift that is allowed from the existing regulations.

This would include 850 Hz RTTY shift too, which will allow good experimentation to further study selective fading.

Mind if I plagiarize that to include in my own comments to the FCC?

P.S.  It would also de-legalize Pactor III and create a different religious war.  (Pactor III is 2K20J2D emission.)
