Using 10,000 watts day and night on 1210 kHz, KGYN Guymon, Oklahoma was heard in a large area of the western United States in 1970. Currently, there are other stations on the channel in the West, making reception more difficult except near Guymon. I remember one evening in January 1970 when I tried for WCAU 1210 in Philadelphia, KGYN was there instead. So I sent a reception report to the station for which they responded with the nice QSL card which features the Oklahoma Panhandle.
Today, KGYN’s format is full service featuring news, sports, and agricultural programming.
