On the surface, it seems like CW usage should be in a decline because 1) CW is no longer required to get a license in most countries and 2) digital modes like FT8 are clearly superior at very low signal-to-noise ratios.
But the bands tell the opposite story, as crowded as they often are. I think the primary reason to use CW these days is because it's fun, it feels like you're really doing something and not just delegating the whole task to the computer, and CW is definitely far better than SSB for DX at low, possibly QRP, power.
In the amateur radio community, yes. You probably know this, but for those who might not: CW isn’t totally synonymous with Morse code.
Morse is the encoding scheme; CW is one particular method of transmission. You could instead flash a light source, or you could use FM radio, or… I don’t know… use smoke signals! CW (‘continuous wave’) just means ‘pulsing a carrier wave on and off’.
I've always wanted to make a messaging app that would vibrate in Morse code when you get a message. I love the idea of feeling a message in my pocket and 'reading' it without looking, but I'm also not great at deciphering it, so it wouldn't get much use.
I've been a licensed HAM for a while, but what actually prompted me to start learning Morse code was when I was troubleshooting some hardware that only had a blinking light to communicate back to me. Instead or print statements, I started using blinks to tell me what was happening. I realized it would be so much faster if I knew Morse code.
LICW is a great place to learn. But I also recently discovered https://morsecode.world/ and really like it.
I work in tech for a school district. Just the other day, a request came in to unblock a Morse code learning website. Initially I was hesitant as, I was concerned kids could harass one another using codes. I was surprised to find a nicely built educational site- https://morsefree.com/
Me and the other nerds used to send each other notes written in Morse code in high school.
This site is timely. Just the other day I turned on the emergency setting on my flashlight and thought oh that's an interesting pattern. Why would it flash three long then three short then three long? About 30 seconds later I realized that I had forgotten an entire alphabet.
Yes! I love Morse. I copy in my head and I send with an Iambic paddle and straight key.
I like to be able to build the smallest possible radios--and nothing's simpler than a CW transmitter. I have a 5 watt transceiver (based on a Si48xx rx chip) that fits in an altoid tin I use when I travel. Hang a wire off the hotel balcony (I have a mini EFHW tuner, too) and start making contacts.
I've been an "extra" since 1977, so we had to learn code back then. I also have the (now-obsolete) first class radiotelegraph licence where I had to copy code at an FCC field office at 25 WPM for 5 minutes in order to pass....
Related: The book "The Victorian Internet" [0] by Tom Standage was very interesting. I never realized how many social things that were impacted by the broad use of the telegraph would have future analogs during the dotcom age.
Highly recommend!

On http://websdr.ewi.utwente.nl:8901/ you can still see and listen to people using Morse code live in the purple amateur radio bands, usually on the lower frequencies (left part of the purple ranges)
As a kid I didn't have a phone, but my parents gave me a cheap iPod Nano. I flashed a custom OS on it (RockBox), which used Morse code as the primary input, since iPods only have a single button.
Programming in lua and writing my diary in Morse code on this microscopic device was a lot of fun.
Morse was a clever way to bypass limitations, which is the definition of hacking itself.
The time has apparently come for yet another Unix command line program to be turned into a huge unnecessary web site. This time it’s “morse”: <https://manpages.debian.org/jump?q=bcd>
Long ago at a startup, In-System Design, I was on a team that made one of the first USB-to-ATA mass storage adapter chips. Small company, having fun, one of us put in an easter egg so that when the drive was plugged in and before the OS enumerated it the drive activity light would blink our team cheer, "ISD rocks!", in morse. He even added a test to make sure it worked in verilog simulation.
The chip was fairly successful and years later someone out in the world noticed the funny blinking on their retail USB drive that used it and they figured it out. They wrote a letter to the editor of Byte or Dr. Dobbs or something, wondering what the message "Sis you rock!" meant. Twisted sister fan, maybe?
We saw the letter in the magazine and were chuffed that our easter egg had hatched but... It turns out the designer had typoed the table of ASCII-to-morse values and dot/dash timing he used to build the messaging circuit, so it really was saying "Sis you rock!". And because he also wrote the test it didn't catch the error. Doh!
We sold badges at DEFCON31 that had a Morse code blinking option. Have to go back and look at the code to remember if it just flashed DEFCON or something else
We also had an option to connect up via serial and it would dump DEFCON or our team name at the terminal and we had games on the terminal. Amongst other things our badge did, it was a great value for $20
is anyone going to point out that the linked website is absolute AI-generated ad-filled slop? or is this just a comments thread starter for "hey, morse code, right?"
