plenty of cw usage in the radio world

Like 1/3 of all Escape Rooms use it.

The Wordle spinoff Morsle (https://morsle.fun/) inspired me to learn Morse this year. It's been surprisingly enjoyable listening exercise.

People who use it call it CW https://longislandcwclub.org/

Every ham radio operator kind of aspires to use it regularly!

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 learning it, mostly as a fun hobby.

I journal a little bit about my experience here: https://owoga.com/posts/2025-03-18-learning-morse-code/

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....
