So what? Amateurs choose the mode they want to use. What is wrong with
choosing Morse Code and HF operation?

Now, now, Jimmie, you are assigning some "blame" on a plain
and simple factual statement: "Amateur radio is the ONLY
[US] radio service still using morse radiotelegraphy for
communications purposes."

What I wrote is a plain and simple fact.

You seem to be in denial, unable to accept a plain and simple
fact. Your problem, not mine.

Some may say the Morse Code *test* is outmoded. But you are saying the
*use* of Morse Code is outmoded!

Yes, in every other radio service except amateur.

You seem to be in denial, unable to accept a plain and simple
fact. Your problem, not mine.


FM broadcasting is the only radio service that uses stereo multiplex FM
- is it outmoded?

There is NO SUCH THING as "stereo multiplex FM" mode.

FM broadcasting is NOT the "only radio service" using stereophonic
audio modulation. Stereophonic audio modulation is NOT required
by FM band broadcasters. Those broadcasters MAY use stereophonic
audio OR they may use monophonic audio plus a SUBCARRIER separate
audio channel OR they may use stereophonic audio PLUS the
subcarrier audio. The term "multiplex" applies to SEPARATE
information sources, not stereophonic audio. All of that is
very much in use today.

DTV (Digital TeleVision) broadcasting carries QUADRAPHONIC audio
(optional, may be monophonic or stereophonic) with or without
extra separate audio subchannels, with or without audio text
("Teletext") accompanying the video. That is very much in use
today and for the foreseeable future of American TV broadcasting.

Some AM broadcasters are still using the Motorola C-QUAM system
for stereophonic broadcasting where each stereo "channel" takes
one of the two DSB sidebands. While that system works well,
the AM broadcasting listener market has NOT received it well
enough to warrant more than a few broadcasters adopting it or
any similar AM stereophonic system. It appears to be on the
way out due to listener non-acceptance.

"Shortwave" broadcasting is still "testing" Radio Mondial
system which is capable of stereophonic audio transmission.
Technically the system works very well. The increased cost
of receivers and the general downturn in world interest in
"shortwave" broadcasting might result in a future
discontinuance. Note: What was once "shortwave" radio
broadcasting is increasingly shifting over to satellite
relay and VoIP dissemination rather than maintaining the
HF transmitters; program content remains the same.

The International Civil Airways VOR (Very high frequency
Omnidirectional radio Range) system ground stations ALWAYS
broadcast with a subcarrier (9.96 KHz) that is FMed with
the reference magnetic azimuth bearing phase. The RF
output is amplitude modulated with 30% AM so that any
receiver can determine its magnetic bearing to the ground
station by comparing the demodulated reference phase with
the main AM phase. Relatively simple receiver demod that
was devised in vacuum tube architecture times. In use
since 1955 worldwide, no foreseeable discontinuance in the
future despite wider use of GPS.

Multi-channel (many "multis") using FM was once the choice
of trans-continental microwave radio relay, the linkage
across the USA that made national TV and 'dial-anywhere'
long distance telephony possible. It has been largely
replaced by optical fiber relay using digital multiplexing
of voice and TV channels using digital modulation of laser
light. The longest (to date) fiber-optic relay is the
long, long like between London and Tokyo through the
Mediterranean Sea past Saudi Arabia, India, around
southeast Asia, past the Phillippines. Most of it under
water. Optical "pumping" with a second optical wave-
length is used for amplification to avoid electronic
repeater amplifiers. Such optical pumping (amplification)
is not possible with microwave RF radio relay.

There are many different other examples of "FM"-like
modulations at work daily in HF and on up into the micro-
waves. The most common is the various adaptations of the
common dial-up modem using combinatorial amplitude and
phase modulation of an audio carrier wave. Those are the
"TORs" (Teleprinter Over Radio) used for data
communications in maritime service; voice is done via SSB
and may be simultaneous with the data. This is on-going
in use and for the foreseeable future.

The FIRST HF Single Sideband circuits (since the beginning
of the 1930s) used combinatorial modulations. The 12 KHz
bandwidth was composed of four 3 KHz wide separate one-way
channels. Each 3 KHz (voice bandwidth) channel could carry
up to 6 frequency-shift-modulated teleprinter channels.
The common arrangement worldwide (by both commercial and
government users) was to use two 3 KHz channels solely
for voice/telephony and the remaining two for 8 to 12 TTY
circuits (number dependent on the redundancy required to
overcome selective fading). While those "commercial" SSB
circuits were numerous from the 40s on into the 70s, their
number has dwindled due to better throughput and reliability
from satellite radio relay services.

Was there anything else technical about communications
and/or broadcasting that you wanted to erroneously state?

Whewww. That was a gassy one.

We don't need to hear about your sex life.

You seem pretty knowledgeable so I need some assistance at
understanding something.

What I can't understand is the the incredibly childish attitude of
some of the pro-coders here. For me, the confusion stems from having
known several old timer hams while growing up. I looked up to them.
They were older gentlemen that had some fascinating knowledge and
great stories to tell about their ham radio hobby. This was back in
the 60's and early 70's so they are all gone now.

I am sure now that they are spinning in their graves, after the spew
puked up by some of the pro-coders.

Not all of them, to be fair, but a few loud ones stand out.

I still can't figure out how a statement about how CW is just beeps[
as opposed to voice on the same hardware] became transmuted into a
requirement that I should hate usenet.
That kind of blatant mis-direction seems to be quite common.

The statement is quite simple...a voice on the airwaves can convey
much more information than just the words spoken but CW can only
convey the words. Since the medium and usually the hardware is exactly
the same weather or not a microphone or a key is used, why bother with
a key that is much more limited? Somehow, this relates to pixels on my
screen but I have yet to understand why my opponent felt the need to
misdirect, misrepresent and misquote. Can none of the pro-coders make
a valid point?

Why do some of them feel that insulting my daughter will make their
point valid? Are their points so weak that they resort to vulgar
insults instead of engaging in debate? I usually don't killfile people
but I have made a few exceptions lately.

Now, there will be some spew directed towards my post. They can go
ahead and prove that turning ham into CB will most certainly be a
great improvement to the ARS. I NEVER knew anybody on CB that was as
rude and vulgar as some of the pro-coders here. I can have a nasty
mouth too, at times, but it's always in response to stupidity that is
obviously not to be taken seriously.

And, ironically, *I* am the one told to grow up. That's just too
funny.

Morse Code can convey more than the words - if the operators are
skilled in it.

It's not the same thing as a voice, though. It's a different
communications experience, just as the written word is a different
experience from the spoken word.

the same weather or not a microphone or a key is used, why bother with

Several reasons:

1) It's often *not* the same hardware. You can use much simpler
equipment for Morse Code than for voice modes.

2) It's a different communications experience. (see above). For many of
us, that alone makes it worthwhile.

3) It takes up much less spectrum. With good equipment, five to ten
Morse Code signals can fit in the same spectrum space required by just
one single-sideband voice signal. AM and FM take up even more space on
the band.

4) It's more effective under adverse conditions. A Morse Code signal
typically has about 10-13 dB of advanatage over single-sideband voice.
That's about 2 S-units. Under conditions that make SSB unusable, or
barely usable, Morse Code will often be solid copy with good signals.

There are other reasons, but those four come to mind right now.

Lots of that going around - on both sides. Don't let it bother you - I
sure don't.

I just made a couple of valid points. That doesn't mean there *must* be
a Morse Code test, just that the mode has some good points.

Thank you for making some points in a nice, civilized manner.

My neighbor, when I was about 12 or younger, had a nifty tower setup.
He had 2 tall telephone poles in the ground with enough space between
them for a third pole bolted in near the top, adding almost the full
length of another pole, save for about 6 feet where all three were
bolted together. I was self-supporting.

Yup. Little things about an op's sending can make it as recognizable as
a familiar voice.

btw, the term "fist" is used in the same context as "hand" was used by
that op.

I am not sure how
much more a person can get out of code.

The words, of course. How they are sent can tell a lot, too. It takes a
bit of experience to recognize all the subtleties of Morse Code.

The main point is that skilled Morse Code operators can convey more
than 'just the words'.

It's not the same thing as a voice, though.

I think that is your main point.

Of course.

But wouldn't simpler equipment limit you to code only?

That depends on the exact situation. The important point is that once
you have Morse Code skills, using code-only equipment isn't really a
limitation in most cases.

Simplicity of equipment can be very important in some situations. For
example, if someone wants to actually build their HF Amateur Radio
equipment, it's much simpler and easier to build a Morse Code station
than an equivalent-performance voice station. In portable operations,
the power requirement, size and weight of a Morse Code station can be
less than that of the equivalent voice station.

2) It's a different communications experience. (see above). For many of
us, that alone makes it worthwhile.

I am curious as to what would make it worthwhile.

All sorts of things:

A) You can communicate without talking or typing. (In a world where a
lot of us spend a lot of time on the telephone and computer, being able
to communicate another way can be a real treat!)

B) The exercise of a skill is fun. Consider the person who learns how
to play a musical instrument: do you think making music (performing) is
the same experience as listening to recorded music?

C) Once you have the skills, communicating with Morse Code can be as
easy - or even easier - than using voice.

D) You can use Morse Code in situations where voice could not be used.
For example, suppose you are in a small house, apartment, RV, tent,
etc., and you want to operate without disturbing others (who might be
sleeping, talking, etc.). Of course you can put on headphones so they
don't hear the received signals, but in order to transmit, you have to
talk. Even if you keep your voice down, it can bother others. How many
times have you heard people complain about folks using cell phones in
public? But with Morse Code and a good pair of cans, you can operate
and make less noise than someone typing on a keyboard.

3) It takes up much less spectrum. With good equipment, five to ten
Morse Code signals can fit in the same spectrum space required by just
one single-sideband voice signal. AM and FM take up even more space on
the band.

Some very valid points here.

None of which mean that there *must* be a Morse Code test for an
amateur radio license. I happen to think such a test is a good idea,
but that's just my opinion.

4) It's more effective under adverse conditions. A Morse Code signal
typically has about 10-13 dB of advanatage over single-sideband voice.
That's about 2 S-units. Under conditions that make SSB unusable, or
barely usable, Morse Code will often be solid copy with good signals.

I could see the challenge in this. I remember a certain thrill back
when I was a kid, whenever I managed to make out a distant signal and
recognize where it was broadcast from.

Exactly! The very fact that it takes some skill is part of the fun and
attraction.

There are other reasons, but those four come to mind right now.

Here's one mo

5) The amount of "bad behavior" problems resulting in FCC enforcement
actions is much less from radio amateurs using Morse Code. Just look at
the FCC enforcement letters that address violations of deliberate
interference, obscenity, exceeding license privileges, and other "bad
behavior" problems. Almost all of them are for violations committed
using voice modes, not Morse Code. The difference is much greater than
would be expected from the relative popularity of the modes.

This doesn't mean all voice ops are problems or all Morse Code ops are
saints! All it means is that there's a lot less enforcement problems
from hams actually using Morse Code.

Somehow, this relates to pixels on my
screen but I have yet to understand why my opponent felt the need to
misdirect, misrepresent and misquote.

Lots of that going around - on both sides. Don't let it bother you - I

I just don't like the snotty attitude that makes the ARS look so bad.

Agreed! There's too much of that type of attitude on *both* sides of
the debate.

I am still waiting for my government handout. Never had any government
handouts in the 44 years I have been around.

How does one define "handout"?

For example, is public education of children a government handout? Yes,
many parents with kids in public school pay school taxes, but in most
districts those taxes paid by parents do not cover all of the costs of
the public schools. And the level of taxation does not depend on how
many children the parents have in school. Is public school a government
handout to people with lots of kids?

Or how about tax deductions? Are they a form of government handout? If
you have a mortgage or home equity loan, the interest is deductible. If
you rent, you don't get that deduction. Is that a government handout to
homeowners?

Not trying to be argumentative, just trying to get a clear idea of what
is a handout and what isn't.

Can none of the pro-coders make
a valid point?

I just made a couple of valid points. That doesn't mean there *must* be
a Morse Code test, just that the mode has some good points.

Cool! I recently saw a similar setup used for a repeater antenna in a
wooded area. It blended in much better than metal tower.

The question of whether there should be a Morse Code test for an
amateur radio license really boils down to this: Does such a test do
more good than harm? The answer is always an opinion, not a fact.
