WAMU 88.5 FM

Non-commercial FM radio engineering at 88.5 MHz delivers direct-to-air RF coverage throughout the District of Columbia, Northern Virginia, and suburban Maryland corridors. Originally activated in October 1961 with a modest 4,000-watt transmitter footprint, modern continuous transmissions push high-fidelity spoken-word audio across the central mid-Atlantic basin alongside dedicated digital streaming feeds.

Daily scheduling centers around rigorous local accountability reporting, regional transportation coverage, and nationally syndicated talk productions including 1A. Morning drive slots feature localized segments inserted directly into Morning Edition, alternating between regional transit telemetry, metropolitan political updates, and investigative stories. Field journalists provide continuous regional documentation across varied county lines from Montgomery to Prince William. Additional digital program feeds maintain archival audio access via wamu.org, augmenting terrestrial radio coverage across overlapping municipal areas.
