Huh, I'd forgotten about the letters/numbers CB "call signs".
Your mentioning them somehow has me remembering WWV:
It was interesting back when because although it sounded utterly the same at first listen, there were nuances to what it broadcast. They probably had meaning/significance that I never knew (or knew and forgot..), but I only knew of them "auditorially".
And FWIW, it was a bit jarring to see my high school graduation year in a Midnight Pub post.... >_<
WWV looks cool. Similar to NOAA, which I liked to try to get from as far away as possible on my CCrane handheld radio. I picked up West Kansas from St Louis, MO before, so that was neat
I wasn't here for 1979, I just know there was a shakedown ;)
