Dick Carroll; wrote: It isn't on the FCC's website yet but you can read it here.... http://www.eham.net/articles/6371 If CW does enjoy a 13 dB advantage over SSB, avid DX hounds will choose to learn it and use it on their own. No need for a license test. CW makes for small bandwidth combined with simple equipment. NASA doesn't use CW with its deep space probes, but they have fancy equipment on both ends. I mention this in that NASA does the ultimate in weak signal work, something CW is usually good for on ham bands with simple equipment and trained operators. But there's no CW op on the space probe. And plain old binary FSK has a bit more than a 9 dB weak signal advantage over OOK Morse ... if you slow it down to equivalent data rates ... More modern digital techniques are even better. Some produce perfect copy at s/n ratios where even the best CW operator couldn't even detect the PRESENCE of a CW signal, let alone begin to copy it. However, Dick and other Morse fanatics insist that those modes aren't a suitable option because they (dread the thought) require a computer (and some hardware/software that I'm sure "Shannon doesn't mean squat Dick" couldn't even begin to understand).
