| Implementing a mental dit/dah decoder + lookup table is
| the shortest path to being able to decode written CW ` _
| . ___ _ ` but it will cause you problems trying to
| receive faster CW since you can't count, assemble, lookup
| fast enough to receive at more than 5-8WPM. And even then
| you are generally doing "keyboard copy" where you write
| down the letters as you hear them and then go back to
| actually read the message you received later.

| If your goal is to be "conversational" in CW I suggest you
| crank up the character speed until you are not able to count
| individual dits/dahs anymore. This will probably be somewhere
| in the 25-35WPM range. The goal is "instant character
| recognition" where you hear the sound/shape of the entire
| character rather than counting elements, assembling them in
| your head, and doing a mental hash lookup on the result.
|
| If you have trouble receiving or copying down the 5letter
| groups at this speed resist the temptation to add "farnsworth"
| spacing (extra gaps between letters). Instead increase the word
| spacing until you have enough down time in between to get
| everything copied.

| Just how general purpose is it these days? I learned it for
| amateur radio (a couple years ago), which is probably the only
| "common" place to use Morse. And even there it's all but dead

| It's getting more and more popular within amateur radio. If I
| look on the Parks On The Air spots page, there are currently
| 20 people in a park across the US doing Morse, and I know
| that when I go to a park I can knock out 60 Morse contacts in
| about an hour on one band since there are so many hunters.
|
| Clubs like Long Island CW have thousands of members and run
| classes all day to teach people Morse and help with their
| operating skills. Just this morning I joined the weekly CWOps
| mini contest which is so popular they have it in 4 x 1 hour
| sessions. And that's on top of the 3 medium speed sessions on
| Mondays, and 2 slow speed ones.
|
| There might not be as much ragchew activity but between
| contests, DXers, and POTA, there's CW activity all over the
| bands.

|
| Go here and see a live map of CW contacts picked up by the
| Reverse Beacon Network in the past 10 minutes (only the most
| recent 100, which is the most I could get it to show at

|
| Also, knowing Morse has been my escape room superpower.
| Escape room designers love Morse.

| press as a dash.
|
| There's a good chance you could also just do it with the
