I listened several times to this recording and there are clearly 2 stations on at once! I am certain the opening ID mentions 1380 AM with the call letters WDLW. 6900 is the 5th harmonic of 1380! There was also a mention of Lorain County in one of the ads, so this is likely WDLW located in Lorain County Ohio. Very interesting and good ears on that one Bali_Frank!
