I was an active KOMA listener in the early and middle 60s...and I remember the station ID very clearly from 1966.
Hey, I listened too, in Southern California, and remember that ID as well. In So. Cal. you had to wait until the sun went down, causing the atmospheric conditions to change, thus enabling the signal to bounce off the ionosphere. Even with 50,000 watts, most of the time KOMA wasn't easy to receive in So. Cal., but when it did come in it was cool to see what was being playing on Top 40 radio in the midwest.
