A low-power FM radio station broadcast at 91.3 megahertz can provide audio for events like drive-in movies, concerts, or religious services. Attendees tune their car radios to the designated frequency to receive the audio directly, creating a shared listening experience within a specific location. This setup often offers a cost-effective and convenient way to deliver high-quality sound to a large audience in an outdoor setting.
Utilizing low-power FM broadcasting for localized audio delivery offers distinct advantages. It eliminates the need for extensive speaker systems, reducing setup complexity and potential noise pollution for surrounding areas. The direct transmission to car radios ensures clear reception, even in challenging outdoor environments. Historically, drive-in theaters have relied on this technology, contributing to their nostalgic appeal. This approach also proves valuable for community events, creating an inclusive experience for attendees.
