Most public radio stations settle into a routine of news, talk and the occasional pledge drive. KQED 88.5 has done that reliably for decades, but its history holds a strange detour that most listeners never hear about: a full hour of Pink Floyd, recorded in an empty studio.
Two Lives, One Call Sign
The station first signed on in April 1963 as KXKX, run by the San Francisco Theological Seminary. That version didn't last. When the seminary pulled its support, the signal went dark in 1967. It came back in 1969 as KQED-FM, this time backed by the Bay Area Educational Television Association, the same organization behind public television's KQED Channel 9, according to the station's history. The call letters themselves are a small joke for anyone who remembers geometry class: KQED nods to "quod erat demonstrandum," the Latin phrase that closes a mathematical proof.
A Founding Manager Who Helped Build NPR
Bernard Mayes served as KQED-FM's founding manager, and his influence reached well past San Francisco. He went on to become executive vice president of KQED's television operation and co-founded National Public Radio itself, later serving as its chairman. That connection helps explain why KQED has stayed one of the most listened-to public radio stations in the country, frequently topping Nielsen's San Francisco ratings outright, commercial stations included.
The Hour Nobody Expected
Buried in the archive is a genuine curiosity: An Hour with Pink Floyd, a 1970 studio session recorded without an audience. It aired just twice, once in 1970 and again in 1981, and stands as one of the more unlikely moments in the station's programming history, a reminder that even a public radio institution built on news and analysis has room for the occasional rock and roll footnote.
What's on Today
The current lineup centers on locally produced shows layered over the national NPR schedule, including Forum with Mina Kim and Alexis Madrigal for daily discussion, The California Report for statewide news, and Tech Nation for coverage of the industry that reshaped the region KQED broadcasts into. It is Bay Area journalism built on top of national infrastructure, which is exactly the model Mayes helped establish decades ago.
Tune In
Six decades in, KQED 88.5 remains the Bay Area's benchmark for public radio, and its archive proves it has never been quite as predictable as its reputation suggests. Listen in on Radio Shuffle and hear it live.
