Keith, Respectfully, I think you missed an important part of Joe's post. The rules state-- that for the mode used, not the least broad mode, nor the narrowest mode possible, but for the mode being used...
97.307(a): No amateur station transmission shall occupy more bandwidth than necessary for the information rate and EMISSION TYPE BEING TRANSMITTED, in accordance with good amateur practice. I added the caps for emphasis. So this entire discussion hangs on the question-- is ESSB the same mode as SSB. If it is, then it is not legal, very simple. If ESSB is a different mode than SSB, than this discussion path proves nothing. I am very interested in the answer to this questions as well as a few others are I expect. I just don't know where to find a list of FCC accepted mode definitions. If ESSB is not address in the list, then I believe it would fall under SSB, and as such not be legal. -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info for MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Sun, 2014-04-27 at 14:57 -0700, XE3/K5ENS via Elecraft wrote: > Joe, > > Because there are other narrower digital modes that can do the same thing. > RTTY uses much bandwidth.
