"slower that ALL"??

Dug this up this morning. Goodness, it's getting hard to find anything on
this newsgroup that is really worth even bothering with.

"Morse code is slower than ALL modes." Hmmmm, that's a rather interesting
observation. I think it would have to be determined on when and where. If
there's a CW net in progress and there are not very experienced people, then
it probably would be pretty darned slow--and repetitive.

Kim, you are welcome to hold any belief system you wish, but the
FACT that on-off-keyed "CW" morse IS the slowest communications
mode in use today or in use a half century ago. I've seen it up close
and personal throughout this whole past half century. It is evidenciary
in the REST of the radio communications world.

The only thing "evidencairy" is that you've misrepresented facts
again.

Morse Code is NOT the "slowest communications mode". That title
belongs to the spoken word for formal traffic throughput.

Morse Code, as a mode, has been replaced simply due to it's cost
in human resources and training. I remains the simplist mode and
among the most reliable.

As for your "up close and personal", yet more of your own
over-grandising of your own net worth to the world of "radio". No
evidence exists of any contributions made to the world of "radio" by
any "engineer" by the name of "Leonard H. Anderson"....None.

The slowest teleprinter rates of a half century ago was 60 WPM and,
to some degree still with old, worn-out surplus teleprinters of that
era. With Mark-Space shift of 170 Hz, those old, cranky 60 WPM
Teletypes need less than 400 Hz of bandwidth to transmit in FSK.
Those ancient machines (already around well before Jimmie was
born) can run continuously at 60 WPM throughput as long as they
are fed paper rolls and paper tape. I once watched over 200 such
teleprinters busy, busy working continuously 24/7 in the same
place on several "networks."

And as long as 100% propagation remains intact and 100% machine
operability remains then they would work.

I also worked with those machines.

If an error occurs, you had no means of knowing that until the
end of the transmission unless you were operating a parallel channel
and were asked to stop and restart.

The old electromechanical Teletypes of the 1970s can sustain 100
WPM throughput as long as the old 1940s era machines did. A
modern PC can emulate either of them and go faster, having much
more mass memory to store archives of network messages.

And at the end of a 100WPM teletype transmission, if you had the
same interruption of continuity of the string, you now had even MORE
data that had to be repeated.

It is the EXCEPTIONAL rarity now to find any two morsemen at
each end of a ham radio circuit who can do SUSTAINED "network"
communications by on-off-keyed "CW" morse at 40 WPM for
hours. HOURS. Networks need hours if the number of messages
are great.

For a "network", yes it is.

However the number of operators who can go on for "HOURS" at a
time at 40+ WPM are NOT that big a rarity.

I've known a couple of speed freak morsemen who had regular
QSOs along the California coast, doing bursting rates of about
60 WPM for a minute or so at a time. I took their word for it, not
hearing their ham transmissions. A minute or so at a high rate of
morse is not good enough for real networking, copying down and
recording for later re-transmission of message content.

Two Novices going 5WPM are going 5WPM faster than you can,
Lennie, so what does it matter?

However, under dire circumstances when, presumably, a CW net would be
underway with very experienced communicators and would be the fastest, most
efficient method of communication (hands down, no pun intended). For once,
this is a thread wherein the real point of CW can be highlighted. CW may or
may not ALWAYS be the "one mode that gets through when no other will." But,
it's hard to argue that CW--if clear and done well--is the fastest and most
efficient mode.

Nonsense alive and well only in the imaginative fantasies of mighty
macho morsemen. Real networks don't operate on imagination.
"Error-free" messages don't get relayed through self-glorified boasting.

Nope. Just through practiced, skilled operators.

No imagination. The nets still operate. The resources are still
there.

The rest of the radio communications AND wire communications world
learned that between a full century and a half century ago. That's why
NONE of them use morse code for message communications now.

A lie.

Morse code nets still exist to this day in the "radio
communications world".

All that said, I think that radiotelegraphy IS faster than the old British
and French semaphore communications systems.

All that said, it's also fster than any mode Lennie is presently
licensed to operate.

Morse radio-
telegraphy IS faster than the pony express and IS faster than paper
surface mail. Radiotelegraphy does reach out farther than the human
voice can transmit unaided by anything but the human body.
Other than that, morse radiotelegraphy still remains the slowest
mode of communications available to radio amateurs.

No, it isn't. Word for word, I can still get a message through
faster on a CW net than on a voice net.

Those who want to fantasize that morse is "faster" or "better" will
have to set up a controlled test NOT in morse favor to demonstrate
that alleged fact.

OK...I will allow that a message that says "Got the card, thanks,
Love" might be sent just as fst on a voice net as on CW.

However start sending traffic with multiple addresses, lengthy
text and unusual text with conditions that are "rough", and the
traffic will pass faster on CW than on voice.

Let all those might macho morsemen sustain
20 to 40 WPM continuously for an 8-hour period...and do the
communications with LESS error than any teleprinter circuit.

Macho Morsemen can do it. Untrained, envious ex-technicians
without any radio licensure can't. Period.
