Since every one of these mnemonics requires a two-step mental translation between sound and character, none of these systems are useful for using manual Morse at practical speeds. Amateur radio clubs can provide resources to learn Morse code. Visual mnemonic charts have been devised over the ages. Baden-Powell included one in the Girl Guides handbook in 1918.
