As AB1J pointed out, a better contest mode using FT8-type signal
processing techniques isn't required have anything to do with CW. I
merely included that in my posts to show that digital processing
techniques using FEC, LPDC, and Costas Arrays could be incorporated in a
way that didn't look digital at all, and virtually no different than ...
for example ... CW.
AB1J may have been right that I confused the issue by including mention
of CW, but all it tells me is that nobody is really thinking very
seriously about this stuff anyway if they can't tell the difference.
Thousands of hams have flocked to FT8 because of its superior weak
signal performance in spite of its needlessly rigid format, but almost
nobody in the contesting world is willing to even consider applying
those same processing techniques to a mode more favorable to
contesting. I find that kind of sad, but I'm through flogging this
horse. You will hear no more from me on it.
Over and out,

The point is that CW is not defined by what the operator hears from the speaker or
headphone. It's defined by the RF emission type. In the case of CW it's a single
transmitted RF frequency that is turned on and off in a defined manner in order to encode
information. "Back in the day" passive components were used to shape the RF
envelope to reduce keying bandwidth (key clicks), while modern radios use digital signal
processing techniques to do so. However, the bottom line is that it's a continuous
carrier that's turned on and off.
For the new suggested mode, the question is would contest sponsors consider it
to be CW?

I never suggested any of those things, and they are all totally
superfluous to my proposal. It is an old and completely bogus debating
technique to extrapolate somebody's position to the ridiculous, like you
are doing now.
By the way what you are describing is basically FT8 carried to an
extreme ... and what I have been proposing is the result of me trying to
arrive at something that is different enough from FT8 that it would be a
desirable contesting mode.

It sounds like a universal digital mode that can be translated into
CW, RTTY, PHONE or even Video at the RX end. It can also carry machine
commands to initiate remote printer and print instant QSL cards,
automatically generate and send spot to all the spotting networks.
Spots themselves can carry a code that will tune radios with proper
software to the required frequency and initiate exchange with the
originator. GREAT! And what do we need radio for? With the recent
allowance of self spotting and extensive use of Internet in contests
by ARRL, all contesting should slide into internet and abandon ancient
radio waves media. Sounds like there is no place in this scenario
for human being. END OF HOBBY!
