It won't be required (cw ID) once the software is released to the
public. At least in USA as far as FCC is concerned, no?
I never is the cw ID

Hi
I'm a bit confused with pandanticity of the CW ident.
the classification of the speed of sending morse is weird anyway.
definition of a word ???? definition of a character ????
Why not just take the longest word in the dictionary , multiply that by 20, and
count up all the
letters, I guess someone will want to take the mean average of between an E and
probably a J
so with that you can wind the wick up until you you can send all the characters
in your callsign in
a couple of seconds.
If its going to be read by any gov agency it will be machine read anyway
antidisestablishmentarianism , that was the longest when I was at school

If you knew you had to send an ID with a packet, could you not reduce the
amplitude of the whole
data packet by a db or so and re-allocate that power to the CW ID? It certainly
doesn't have to
be loud, much like repeaters do id-under-voice. That way the FT8 signal taken
by itself would
still be constant envelope, and the CW id could be sent way down at
FDial+100Hz. If the OOK
nature of CW is the issue, you could always treat it as FSK using 1 Hz and
100Hz. The 1Hz
component would get chopped out in the radio, leaving the ID and FT8 signal.

Any chance of having the CW id run concurrently with a data packet, perhaps at
fDial + 100 Hz
or so? It'd meet the id requirement without interfering with QSOs.
Doing it concurrently wouldn't be compatible with FT8 being a 'constant
envelope' mode.
