#32I haven't tried this site, but the most well known for learning Morse in your browser in Ham radio is:
Which uses a similar technique. It also has quite a few more types of practice such as words, callsigns, games, contests etc.
I learnt Morse code there last year before I did a CW academy online course and I really enjoyed the approach.

#33A few years ago I tought myself enough in a few days to be able to chat with people on https://morsecode.me/ I've forgotten it almost all now.
I recently got into Morse and was so proud I could send a message via your tool. Thanks!

#34Earlier quoted context omitted.
Generally CW mode (morse) can be transmitted farther on less power than most other modes, and can be sent and recieved without sophisticated electronics (build your own QRP rig for like $10). But yeah, there's not a lot of utility, even in rare or hypothetical emergencies. Many other things one could focus on.
In apocalypse you'll have a lot of down time to learn Morse.
Interesting. Without grocery stores (et. all) I think most of us will have far less free time.
Re: Koch method to learn Morse
#35Is there a good reason to learn Morse in modern day besides just for kicks? Some sort of survival situation in which your only form of communication would be Morse, and you can't get out of it by sending ASCII binary? Not knocking on anybody's learning for fun, just curious.
Yes, it is important for solving some of the more challenging bomb disposals in the game "Keep talking and nobody explodes" within the alotted time limit :-)
Also i think Morse is sometimes used in Geocaching riddles and CTFs.

On iOS there is Morse Machine, similar idea for single characters. There is also morse.camp, a PWA that focuses on recognizing English words.

> and you can't get out of it by sending ASCII binary?
It's a minor point, but I doubt you'll find many people who can decode binary ASCII in their head (especially in contexts like tapping), not to mention that you'll need 7/8 bits per char instead of the ~3 Morse code uses.

This is because there're different levels: they are similar to EOL, LF and EOF.

> There are three in general use: AR signifies the end of the message, KN marks the end of your transmission and an invitation to the other station to reply, and SK says it’s the end of the contact and your last transmission to that station
See this nice discussion on the nature of morse:
https://cs.stackexchange.com/questions/39920/is-morse-code-b...
> TLDR: We can thus conclude that the Morse code can be understood, and easily analyzed, as the composition of a prefix binary encoding of a 3 symbols alphabet {dot, dash, sep} into a binary alphabet, and a prefix encoding of a 58 symbol alphabet (57 characters and one space) into the 3 letters alphabet.
> The composition itself is a prefix encoding of the 58 symbols into a binary representation.
Check this part:
> However, some people would be inclined to recognize the space DET at level 2, thus making the alphabet quaternary, then using it directly at level 3, encoded as itself in level 2.
> This would meet the standard definition, for DET encoded in binary as 0000. But it would prevent the analysis of the binary encoding C2→1 as a prefix code, making it harder to show that CMorse is a prefix code, hence unambiguous.
In your link, AR, KN and SK can be considered in a similar way, but applied to the decoded message.

Yeah, LCWO is the gold standard for Koch training on the web, and I'd second the suggestion for CW Academy. Having a commitment to learning with other people tends to help you ride out the rough patches.
To help with my own learning, I built a mobile friendly web app/game which includes Koch as an option. It's also open source - https://github.com/mdp/morse.mdp.im - morse.mdp.im
