site DCist in Spring 2018. WAMU relaunched DCist on June 11, 2018. Technical facilities In 2013, WAMU moved to a new studio facility at 4401 Connecticut Ave. NW in the Forest Hills/Van Ness neighborhood of Washington, D.C. The facility was constructed with three broadcast studios, two news studios with dedicated control rooms, multiple editing suites, and a 90-seat black box theater capable of supporting broadcasts before a live studio audience. In total the five-floor WAMU media center supports 21 broadcast and production studios and control rooms and a technical core, as well as 12 conference rooms and community spaces. The IP-based studio infrastructure at the facility helped ensure WAMU staff could work remotely throughout the COVID-19 pandemic. In October 2019, the station launched a major tower renovation and antenna replacement project for its tower on the American University campus. The improvents were designed to improve reception in Northern Virginia and parts of Maryland. During the project, WAMU broadcast from an auxiliary site in Arlington, Virginia. The WAMU antenna also serves WTOP, WPFW, and WETA; the tower also hosts auxiliary antennas for WPGC and WMMJ. Prior to the station's move to Connecticut Avenue, WAMU operated for about two decades from two floors of an office building in Tenleytown near the AU campus that at one point housed the East German embassy. Before that, the station was housed on the AU campus next to its tower. Programming WAMU's main channel carries content from NPR, American Public Media, Public Radio International, and Public Radio Exchange. The station's weekday schedule is largely made up of NPR staples Morning Edition, All Things Considered, Here and Now, The Takeaway, and Fresh Air. , WAMU produces one daily program, 1A, which NPR distributes nationally. The station also airs This American Life. A relay of the BBC World Service is heard overnight and in the 9 a.m. slot on weekdays. WAMU breaks from its general all-news and talk schedule only on weekend nights, which it devotes to entertainment programming; Sunday nights are given to The Big Broadcast, which originated in 1964 as Recollections. This program, which airs for four hours, features rebroadcasts of drama, comedy, and variety shows from the "golden age of radio", including The Jack Benny Show, Dragnet, Gunsmoke, The Great Gildersleeve, Lux Radio Theater, and Philco Radio Time with Bing Crosby. Ed Walker, himself a storied Washington broadcaster, served as the program's host from 1990
