MaxxCasting™ Stations Lead San Francisco’s December Ratings

December 2025 Nielsen Audio ratings in San Francisco clearly demonstrate the competitive power of MaxxCasting™, with four of the market’s top five FM stations now licensing the technology for signal reach. Together, these MaxxCasting-powered stations captured nearly one-quarter of all radio listening among audiences age 6+, underscoring the growing role of coverage optimization in market leadership.

Public radio leader KQED-FM finished December as the #1 station overall, a position it has consistently maintained since activating MaxxCasting. Fellow top-ranked FM stations KOIT, KDFC, KMVQ, and KLLC further illustrate how enhanced and stabilized coverage directly translates into audience share gains in one of the nation’s most competitive radio markets.

San Francisco is widely regarded as one of the most technically complex FM environments in the country, making these results particularly significant. For broadcasters seeking proven, market-tested growth strategies without changing format or content, December’s ratings reinforce a clear takeaway: expanding usable signal reach remains one of the most powerful drivers of both audience and revenue growth.
