Learn basic Morse code

Learn enough Morse code to recognise a few letters without looking them up.

Do it

1. Start with a small group of common letters rather than the whole alphabet.
2. Listen to the rhythm as sound instead of trying to visualise dots and dashes.
3. Practise recognising the letters in random order.
4. Come back tomorrow and see which ones stuck.

What next?

Finish it properly. Then go back and find something else to do.
