I got into radio in the early 70s and spent many hours perusing broadcasting yearbooks and other lists. I recall KIMP and KPXI in Mt Pleasant and KXIT in Dalhart even though I grew up in far south Texas. And when channel 42 here in Austin picked up the KEYE call letters I was the only one who knew they belonged to KEYE-AM/FM in Perryton. The stuff that gets stuck in your brain.
