• Practising for ham radio ASOC exam
• My guess is that the below method is an easier way to memorise it. Let's see what works.

Or in simpler terms:

Morse tree
 - E
   - I family - SHV UF (5432?)
   - A family - RL WPJ (.1)
 - T
   - N family - DBX KCY (6-=;)
   - M family - GZQ O (7,890)

Then practice EIATNM, practice each family separately, then practice multiple families together.

Practise settings

• 8 wpm, farnsworth zero, 700 Hz
• audio generation: Link to app
• sequence generation: LC_ALL=C tr -dc 'EIATNM' </dev/urandom | head -c 1000 | pbcopy
