Morse code isn't obsolete -- it can still extend to greater distances than
voice.

Another advantage of Morse code is that several conversations can
simultaneously exist on a single frequency. Each station uses a tone
different enough to be distinguished by ear and an experienced operator can
mentally filter out all but the tone he's copying.

This is not true.

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.

With BPL coming Morse Code might be the only way left to communicate on HF.

Sorry I'm not a ham and I don't want to see CW go. It call BASICS!
Once you start forgetting about the basics then you start developing a
backwards nation.

Just look at school, they don't teach the basics any more they just
throw the kids on computers. Do you know a single McDonalds employee
who can make change in their head???

CW isn't hard to learn, not even a ham and I can receive 15 WPM and
actually enjoy it....

So you think CW will come through the interference fairly well? I guess
everything will if the range is close enough, like within a few blocks
perhaps. You're probably already aware of it but ARRL conducted some field
experiments in areas where the power companies are testing BPL. I didn't read
the report but I recall hearing that the interference was about S9 in those
areas.

Now that was about a lame argument.
