After consulting DF8ZR and DF6NM, who both are also active in DFCW, I would
like to suggest a kind of temporary DFCW standard in order to enhance DFCW
QSO's and avoid 'collisions' with other modes : >>>>>>>>>>>>>>>>>>>>>>>


All of Rik's standards look useful to me, but it is also essential to specify in the standard that the dash should be the higher (or lower) frequency. This is especially important if KK and RR are to be sent as part of the procedure, as a K is an upside down R !!
I have suggested this before, and it has not been taken up, but I
think that transmissions should start with CT (as one word). This will
make it very easy to determine which element is the dash, and to
find the dot length - bear in mind that there is a 4dB advantage to be
gained by using element lengths of 10s or so, The use of CT is quite
normal to indicate the start of commercial CW traffic so will not be
ambiguous.
