Hello to all,
CCW is a pure digital mode as CW when sent by a computer because it is coded as
another digital mode at a defined speed and it is not difficult to decode
(almost same technic as PSK31 decoding ).
Now when CW is sent by a human being it is a very special digital mode let's
say a "fuzzy digital mode" because the standard is not respected, the speed
must be assessed and variations of dash and dot length must be taken into
account (which is not simple).
It is very complex for a program to decode human CW and it is not so good as a
human ear (this situation being preferible...).
Note: program decoding does not work at all as a human decoding: the second one
decodes entire characters without any analyse of the number of dots and dashes
when the first one decomposes in dots and dashes before deciding for nothing or
for a character.
