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 ...

If you have an optimized receiver and suitable conditions, maybe - depends on
what you determine to be "equivalent data rates".

But hams don't do slow-HF-BFSK. 60 wpm FSK Baudot RTTY is about the most basic
data mode still in use by hams.

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.

That all depends on the equipment in use. Using a receiver optimized for one
mode in an attempt to receive another may or may not be a good idea.

What mode do you use most on HF, Carl?
