One of radio’s most recognizable personalities has officially called it a career.
After more than 24 years with SiriusXM and an incredible 53-year run in broadcasting, Spyder Harrison has announced his retirement, closing the book on a career that spanned some of America’s biggest radio stations and satellite radio channels.
In recent years, Harrison was heard weekdays on The 10s Spot, while also hosting countdown programs on SiriusXM Hits 1 and 90s on 9. Fans of 70s on 7 also knew him through his longtime alter ego, JJ Walker, a character that became another signature part of his on-air legacy.
Long before satellite radio, Harrison built a reputation as one of Top 40 radio’s most energetic personalities. His career included memorable stops at stations in Detroit, New York, Miami, Philadelphia, Minneapolis, Tampa, and Orlando, where listeners knew him by several on-air names, including “The Jammer.” His high-energy presentation and unmistakable style helped define multiple eras of contemporary radio.
In announcing his retirement, Harrison expressed gratitude to listeners who supported him throughout his decades on the air and thanked the colleagues who stood beside him during his years at SiriusXM.
Few broadcasters remain behind the microphone for more than half a century. Fewer still successfully navigate the evolution from terrestrial radio to satellite broadcasting while continuing to connect with generations of listeners.
For Spyder Harrison, that journey has now reached its final sign-off—but the impact of his voice will continue to echo throughout the radio industry for years to come.
