The European tradition is to use primarily male names for the phonetic alphabet in non-English related languages. The table below (from DIN 5009) shows the German standard phonetic alphabet compared to the ITU/ICAO. Similar standards exist in other languages. Another aspect is that most younger people are completely clueless of phonetics, regardless of standard used. Trivia: Recently, there have been raised objections about that the Swedish phonetic alphabet is all-male. A proposal for a new standard using half female names has been submitted. 73/ Karl-Arne SM0AOM
