I was always fascinated by radio, passed the RAE and got my license at 14. No morse code - so I was only licensed to use 2m and up, but vhf / uhf was what really interested me so... Many years later they dropped the morse requirement so I can use hf these days, use 18m quite a lot for FT8 type modes.

While we are celebrating Morse, let's also remember his co-inventor Alfred Vail - Wikipedia - often overlooked.

Morse's 1844 code gradually fell out of use. Gerke's Continental Code of 1848 changed half the letters, all the numerals, and simplified spacing (reducing "hog-Morse"). It happened to be faster on very-long undersea cables (original Morse is mildly faster on short lines with low dispersion). Continental swept Europe and then ship-radio. 1912 it was declared default for radiotelegrams. Continental changed again to be ITU. "American Morse" lingered on US landlines, lake-ships, railroads, and a few hams, but is now mostly brushed-up for Civil War re-enactments.

OTOH, these are just "dialects" of the same basic idea, one which was not obvious when Morse started. (Cooke and Wheatstone's multiple-wire telegraphs already existed, and they had single-needle in 1843, before Morse's 1844 demonstration.)

It's not a code, it's a cypher, and Morse didn't wholly invent it, he had a lot of help, nevertheless, it made a huge step frward in long distance communication even if it did put a fair few horse dealers out of business...

Ok, so here is my story.

I tried several times as a teenager to learn code and never got it, including in boy scouts.

1971 I joined the NAVY. I volunteered for flight duty and Radio Operator. Ta-Da, I'll have to learn code now!

NIX! Radio operator school and I learn we are the first class to NOT BE REQUIRED to learn code.

Instead, we need to learn to type!

I took typing in HS as a summer course for failing literature.

60wpm

I ended up helping others to learn to type.

My dad was a general class license from the old days (WB4DBL, Willy Baker Four DeciBell Low). When the no-code Technician license became available my brother and I both got our ticket. We used to chat with my dad on my way home from work every evening through the Mt Mitchell 2M repeater.

When Pop passed away, I dropped my ticket. I only did it for him.

I can still find my call sign on the Internet KD4IMY (Kilo Delta Four India Mike Yanque). I guess it has not been re-assigned yet.

... Its only one note of two different durations.
That's the goal, but you could hear plenty of chirps, clicks, hum, buzzes and other junk, sometimes all of it on one signal, and if a guy had ( has ) a bad fist, even the timing and duration would be all over the place ... the bands sound a lot better these days.

I was going to post up a pic of my paddles - mine are made by MFJ, otherwise they look just like RajkoM's - except less dusty ... I guess MFJ bought out Bencher?

This can usually be reduced with xtal filters in the IF stage.
