Re: Koch method to learn Morse
#22Wow this is interesting, I probably am going to learn this way. But I've read the Morse code is deprecated and isn't used anywhere IRL anymore. Isn't it?
Ham radio operators still use it, it's just required for licenses in United States anymore. I believe radiobeacons still use them as part of their identification protocol in aviation as well.
I think you're missing a "not"

Initially, I learned it for fun and ham radio emitting. But I find it fascinating that you can use it with anything that can be turned on and off with a rythm. I used a flashlight to say "hello" while waiting for a fireworks event, but the other person far away just blinked their flashlight randomly in response. I guess it could be used for worst scenario speech, like blinking eyes for examples if I ever have a terri…
Use double tones/knocks if you don't have long.
Then how do you distinguish between "long" and "two shorts"?

Sure, but how does knowing Morse help in those scenarios.
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.

#25Does learning to transcribe morse->letters at this speed mean you can also do letters->morse in a traditional morse keyer?

It's useful in any situation where you're trying to make the most efficient use of the power available to you. The classic example is communicating with the other side of the world with minimal power, but it's also useful in any situation where there's a lot of path loss, like when HF propagation conditions to your desired station are terrible or if you're bouncing radio signals off the moon. There are computer-based…
Do you listen/read/write in Morse, or use a computer to translate?
I mostly send with a paddle and decode with my ears. I sometimes use keyer memory to play back messages.

#27Does learning to transcribe morse->letters at this speed mean you can also do letters->morse in a traditional morse keyer?
Generally yes. Sending morse is much easier than receiving it. Once you are comfortable receiving morse at 25wpm for example, the amount of practice needed to send at that speed is pretty minimal.
Re: Koch method to learn Morse
#28Is 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.
In ‘The Diving Bell and the Butterfly’ there is a point where the author, who is suffering locked-in syndrome after a stroke, is communicating by having the letters of the alphabet shown to him one at a time, with him choosing by making the one small gesture he is capable of. Morse code could be much more efficient here, and perhaps more efficient than a binary-search version of the alphabet method.

Somewhat. There's a skill to the timing that needs to be picked up in addition to the patterns you learn when learning to copy. Ideally, you're also practicing sending with some kind of local oscillator or your radio set to monitor mode. One reinforces the other.

#30Are new letters usually introduced in a particular order?
Yes, though it's not hard and fast. Many sites will teach the Koch method but often with subtly different ordering, and very different from his original ordering. CW Academy teaches based on how frequently you'll hear them on the air. Long Island CW Club has changed to another system.
Most systems these days though focus on learning a couple letters and then progressively adding more on as you improve.
