Walt,
There are typically "layers" of stations on many of the bands. It
depends upon your antenna system and to a certain extent, operator
skill, when attempting to work really weak stations. It is not uncommon
for wall to wall signals where you can not find a decent open area. Not
to mention
If we do,
I believe that we have adequate space for even some 10 KHz bandwidth modes.

Walt,
I understand. My diatribe was to make the point that the occupied bandwidth
has a bearing on the general acceptance of a mode.

From a regulatory standpoint I don't think there is a problem. I think

This should read there is no requirement for the emission to be FSK or PSK.

Mark and group,
When you say the "entire waveform is one symbol," could you expand that
a bit. What do you mean by "the waveform." Do you mean the total
waveform of the emission spread out over the l KHz or 2 KHz bandwidth?
I am probably just not understanding this correctly but if there are 64

The entire waveform is one symbol. There are 10 symbols per
book
used to be available from the Air Force MARS Library at Scott AFB.

Bonnie,
If MT-63 is legal on the ham bands, since each tone runs at 10 or 20
baud depending upon the commonly used versions of this mode, but has 64
tones, it would seem that it is running well over 300 baud when you
consider the entire waveform.
The question that I need to be clear on is how

I KNOW you wrote this before I sent out my E-Mails this morning...but..."just

"Its easier to ask forgiveness that permissions."
You have captured what I have said for 3 years now...someone PLEASE (I am
begging) for a mode that has X number of tones, 40-50 baud per tone

I've never heard of the FCC citing anybody for using more then 300 baud.
Selective Enforcement is, I believe, a legitimate option.
