The Mighty 1090

 

For much of America, Little Rock (Pulaski County) was at one time just another dot on the map. But after sunset in the 1960s and 1970s, one Arkansas radio station changed that forever. Across the Great Plains, deep into the Midwest, and even into Cuba, listeners slowly turned their radio dials until they found a powerful signal on 1090 AM: KAAY.

Known as “The Mighty 1090,” KAAY became one of the most influential radio stations in the South and, in many ways, one of the most important stations in the U.S. Its 50,000-watt clear-channel signal traveled vast distances at night, allowing people hundreds (and sometimes thousands) of miles away to hear a station broadcasting from West 7^th Street in Arkansas’s capital city.

During the day, KAAY operated as one of the South’s dominant Top 40 powerhouses. But after dark, the station transformed into something entirely different.

Beginning in 1966, KAAY launched the groundbreaking underground music program Beaker Street, hosted by smooth-voiced deejay Clyde Clifford, whose real name was Dale Seidenschwarz. Ironically, Clyde Clifford was not a stage name he created himself, but the name of the comptroller of KAAY’s parent company, LIN Broadcasting. In fact, all of KAAY’s deejays adopted on-air names borrowed from members of LIN’s board of directors and executive team.

At a time when most AM stations relied on tightly controlled three-minute pop singles, Beaker Street broke every norm. Long album cuts, psychedelic rock, blues, folk, and experimental music flowed through Arkansas airwaves into bedrooms, businesses, and car radios across North America. For countless listeners, it became their first exposure to artists who would later become legends. Before long, Beaker Street itself took on an almost mythical reputation.

Part of that mystique came from Clifford’s delivery. His slow, deliberate voice stood in sharp contrast to the rapid-fire style common in radio at the time. Strange background sounds drifted beneath his words, creating an eerie late-night atmosphere listeners still remember to this day. The effect was partly practical; the show was often broadcast from KAAY’s transmitter site in Wrightsville rather than the downtown Little Rock studio, and the sounds helped mask transmitter noise. But the result felt almost hypnotic. To teenagers in remote towns throughout the Midwest and South, KAAY sounded less like a radio station and more like a message from another world.

What made the station even more remarkable was its extraordinary reach. Thanks to its powerful nighttime signal, KAAY could be heard far beyond Arkansas. Reports say KAAY could be heard as far north as Canada and as far south as Cuba. During the Cold War, young Cubans secretly tuned in to hear American rock music that was otherwise difficult to access under tight government restrictions.

Think about that for a moment: a radio station in Little Rock influencing underground music culture across an entire hemisphere. That kind of influence is difficult to imagine today in an era dominated by streaming services and social media. Modern audiences can instantly hear virtually any song ever recorded. But during radio’s golden age, stations like KAAY served as cultural gatekeepers. They introduced listeners to new sounds, new ideas, and entirely new ways of thinking, and KAAY was doing it from right here in the Natural State.

The station’s history stretches back further. KAAY originally began as KTHS (which stood for “Kum to Hot Springs”) in Hot Springs (Garland County) in the 1920s, before eventually becoming KAAY in 1962. Over time, the station evolved through different formats as FM radio gradually overtook AM as the dominant home for music broadcasting. By 1985, KAAY officially ended its run as a Top 40 giant and transitioned to religious programming.

Even so, the station’s legacy never disappeared. To this day, older music fans still speak reverently about Beaker Street and the thrill of hearing that distant nighttime signal rolling through the static. Archived recordings and surviving airchecks have become treasured pieces of broadcasting history, and radio historians now recognize KAAY as a pioneering force that helped shape the future of album-oriented rock radio. If you’d like to hear some of those rare recordings and vintage airchecks, they’re available on a website maintained by former employees of KAAY: mighty1090kaay.blogspot.com

In Arkansas, we often underestimate the significant contributions our state has made to American culture. Yet for one remarkable era, some of the most adventurous and influential radio in the nation came not from New York or Los Angeles, but from a transmitter outside Little Rock.
