If the "tone" is different at all, then the carrier is on a different
frequency.

Two (or more) CW transmissions on the same frequency will have the identical
"tone".

You can fit CW transmissions very close together, but not on the same
"single frequency".


If it's code, it's not on a single frequency in the first place. Not only
theorically! Listen to code through a 10Hz filter and it's nearly uncopyiable.

The audio effect is that the filter rings as loudly as the signal. But it's
actually a mathematical effect. You're cutting out too much of the bandwidth
that the code actually occupies.

OK, I was under the impression that a tone was transmitter on the carrier and
that the tone could be adjusted. But that would be modulation.

A single freq is not possible. You're only picking on words. "A single
frequency" always implies the frequency that the signal is centered on.

Another advantage is that CW has a narrower bandwidth than any voice
modulated signal.
