I enjoyed the complaining about q codes :) as a ham radio operator who does a lot of Morse code, I can tell you that they are far far from dead. QRL, QRZ, QSL and more are heard or sent over the air tens of thousands of times a day.
Also the radio call signs of hams primarily start with either k, n, w, a in the USA. Airplanes have radios, so that’s why they treat those letters in a similar way along with fm/am radio stations
