That mode is included in SpecLab so it would be no problem. I never used 
it so far. I've just done a test, generating my call in a spectrogram 
using your settings, see attached.
That's not really nice i find. Maybe a bit more time efficient but quite 
confusing when signals are buried in the noise. In DFCW you know the 
dashes are only present on 2 frequencies. So the shift is defined. That 
is an additional information that becomes relevant when the characters 
are still not clearly detectable.
So i will go on in DFCW-180.
Let's keep the challenge and wait to the end of the week, as you say :-)
Then we can go for DFCW-120.

73, Stefan/DK7FC
