This is a short clip and the audio quality is fair at best. But I wanted to feature it here since KOMA is a legendary station and tapes of this era are relatively scarce.
I recorded this from Minnesota when I was 8 years old, using a Spartan/Atlantic “shoebox” recorder. An Audio Magnetics “bag cassette” (3 for 99 cents on sale) completed my arsenal of highly sophisticated recording equipment. Keeping my hand as steady as I could, I held the pencil mic next to the speaker of my $10 Midland AM clock radio. The receiver sensitivity of this radio was extremely poor. You can hear it “squeal” as I tune the dial. The fact that I could even hear KOMA from 800 miles away on this radio is a testament to the strength of that big 50,000 watt nighttime signal on 1520!
