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.


Don't exaggerate, Leonard. You might have seen it up close but for you,
it wasn't personal.

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."

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.


Actually, many of the old Mod 26's, a relic of the '60s could do 100
wpm.
They couldn't do it in the presence of heavy static or multipath flutter
or echo though, even with the use of modern digital "helpers" such as
various HF link enhancement devices.

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.


....and you know this because of your vast experience in the use of
morse?

One thing for su It is certainly a rarity to find TWO morse ops at
each end of a circuit.


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.


They certainly don't, even if TTY machines are being used on an HF
circuit.


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. 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.


You surely don't know much about radio contesting, do you, Leonard?

I'll allege that you are the original "might" macho type.
