I worked at KTOW from April 1968 to the end of December 1968. KTOW was in a building in downtown Sand Springs, and yes the tower was mounted on the second floor roof. The transmitter faced the control room. And yes, the ground straps, such as they were, ran down the side of the building. 1340 was a Class 4 AM station. Class 4's or "Local Class" stations ran 1000 watts daytime, and 250 watts at night with non-directional antennas. KTOW signal covered most of Tulsa in the daytime, and barely got out of Sand Springs at night. At the time, they were the only country station in Tulsa, so even with the terrible signal had good ratings. Until 1962 or 1963, they could only run 250 watts day and night, but then the FCC allowed them to a kilowatt daytime. I used to drive to Oklahoma City frequently and would leave the car radio on 1340. Around Stroud KTOW and KOCY would interfere with each other, but only for a few miles, then one would over run the other depending on whether I was go to OKC or coming back to Tulsa. At about the same that the FCC permitted the power increase, they also implemented the Third Class Radio-Telephone license as a requirement to operate non-directional stations. When I went to Dallas in September 1964 to take the third phone test, there were a number of older guys taking the test to keep their jobs. They were really sweating bullets over having to pass the test. Buddy Powell owned KTOW at the time, he was great to work for. Dean Jenkins (Kelly) was the PD and I was the news director. I replaced Bob Losure when he left to do news at KAKC.
