@VDCdriver–I am a little before your time, so I listened to WOWO in the mid to late 1950s. The DJ’s back then were Bob Siever, Jack Underwood, Bob Chase and another one that I don’t remember. I lived about 60 miles from Fort Wayne and WOWO was a 50,000 watt station, so the signal was very clear.
The station many of us listened to in these old days was a station from Nashville, TN that featured Randy’s Record Shop at night. I adjusted radios for several of my friends to pick up this station.
In your time period (early to mid 1960s, I was working on my master’s degree at Southern Illinois University in Carbondale, IIl. The station of choice down there was KMOX in St. Louis, Mo. I haven’t tried to tune in any of the above AM stations for decades.
