BS, the services realized that with modern technology CW is an outdated,
antiquated mode, no longer useful to them. You are living in your ham

radio
dream world too stubborn to see the truth.

Hey JJ -- did you forget that SSB is over 60 years old? By your logic,

it's
time to shut that antiquated puppy down as well. I mean, there are MUCH
more modern modes out there, right? Or are you too stubborn to see the
truth?

Arnie,

The technical fact of the matter is that SSB is just about as efficient as
it
gets for voice communications. The baseband (audio frequencies) are
translated to RF and back, with the result that the RF signal is no wider
than
required to convey the baseband bandwidth. (unless, of course you're
running things into clipping and causing all sorts of intermod products)

While digital voice has some advantages in some applications (particularly
if one wants to use mixed media, such as VOIP links), even the best
low-rate codecs require a bandwidth at least as wide as SSB and at those
coding rates don't provide the same fidelity (speaker recognition, tonal
quality, etc.) due to the coding involved.

Yes, SSB is at least 60 years old ... but Morse is what? About 3X as
old?

Its not simply a matter of age ...
