I was lucky enough as a kid to inherit my grandfather's collection of old sci-fi books. I first became aware of Q codes through the short story "QRM Interplanetary" from 1942 (https://en.wikipedia.org/wiki/Venus_Equilateral https://en.wikipedia.org/wiki/Venus_Equilateral). I find it interesting that Q codes have changed so little over the last century. I have some ham radio friends who will use Q codes when talking face-to-face with each other, and the codes they use are basically the same ones from the original list.
