I’ll turn 70 this summer. I’ve seen a LOT of changes in these decades. For me, the biggest changes have been in my chosen career, communications. I started off in the Air Force, which in 1960 still used a lot of Army protocols. I learned the Morse code at Goodfellow AFB, TX, and went to “copy” code throughout my long career. Sadly now, the only time I hear any code is in the background on the Military Channel. I also learned HF radio teletype operations. I doubt now if there are any single-channel FSK tty circuits anywhere in the civilized world. It’s as if all the data being transmitted anywhere in the world were being forced into a single straw and now it is a virtual flood of 1s and 0s. And no more Birely’s or Nesbitt’s orange pop.
