Do you think to be a real amateur radio operator if you play morse code with a computer?
Everybody can complete the DXCC in CW with a computer and a linear amplifier, but if this is valid for ARRL, this has no sense for the community of operator that still practicing morse code.
You can decrypt whatever you want, but you have to know: you are not making anything more that looking into a computer screen. The machine is making the work instead your brain.
So, onece again: CW Skimmer is not hamradio!
