The Apple DOS 3.3 disk (early 1980's) came with a simple program, included
as a programming example, that did a fine job of copying code/CW. I hooked
an unused Apple II Plus to a Kenwood R2000 shortwave receiver and used that
program to copy code for several months. It rarely missed characters and
almost never missed enough characters to make the message unreadable. The
only times that program failed was when the signal I was trying to copy was
too deeply buried in the background noise or when multiple stations were
transmitting on the same frequency.

I haven't purchased a program like that recently, but surely they've
gotten better over the years. Is that not the case?

No they haven't. The two conditions you state are still problems and good
reasons to learn to copy by ear. The human brain can sort it out when the
computer cannot. Poorly sent and spaced code is also still a problem.

We've had this argument before and you have formed a concensus of ONE!

Brian, I think you missed the letter N in the word "ONE." :-)

No they haven't.

They HAVE, but there's no market for such things, not even with the
Military Intelligence School at Fort Huachuca on ELINT training.

Which is NO reason to mandate code testing for an AMATEUR radio
license by the government.

The human brain can sort it out when the
computer cannot.

Then all the other radio services "should" have used it for communications,
right?

Wrong. All the other radio services involved in communications have
either DROPPED it or never considered it in the first place.

Poorly sent and spaced code is also still a problem.

So?

US radio amateurs who do NOT use morse code modes (the majority)
don't require morsemanship skills.

They have, but the mighty morsemen consider such to be desecrations
of the will of the old radio gods.

Perhaps you missed a back-and-forth I had in here with Ed Hare on a
programmer acquaintence who wrote an adaptive morse code cognition
program (on a standard PC, top of the line then, middle-level now) which
could compensate very well for variations in spacing, dot-dash lengths,
whatever "swing" is (a subjective term to morsemen), tone, rate, and
so forth. To him it was an intellectual challenge.

Some trials with my receiver and a long-wire antenna at his place
showed that there was damn little USE of morse code anywhere on HF
except in the amateur bands. There's no real market for such a thing
and the successful adaptive morse code cognition program remained
just a satisfying (to the programmer) intellectual exercise.

Well, I suspected the programs might have gotten at least somewhat better
over the years. The author of the program I had wrote about trying to
compensate for bad code by looking for patterns instead of focusing on each
individual dot and dash as it was being sent. The program also didn't use
hard rules for dot, dash, and space, length, instead interpretating each as
it went along. Obviously, I don't know the details, but the program did do a
pretty good job considering it was just a simple programming example
included with an operating system. My only complaint was that it didn't send
code like some of the other programs advertised, but I couldn't have used
that back then anyway.

What is "habd-sent CW?" :-)

You HAVE evaluated "most" computer morse programs and "proved"
your banana-boat swing can "thwart" them, senior? :-)

I rather suspect you know NOTHING of the abilities of computer
programs' abilities for receiving morse.

Please send your gas-baggery to Lakehurst, NJ.

beep, beep, BOOM! :-)

Seems like Morse Ops need to send better.
