When the Nationals arrived in Washington, D. C., MASN acquired the television rights for almost all Nationals games. However, MASN was not available to most people in the Nationals broadcast area for nearly all of the first 2 seasons in DC. Some of the games were also televised on WDCA, mostly on weekends.
While MASN continued to televise nearly every Nationals game, the number of WDCA telecasts decreased to approximately 30 in 2006, mostly on Friday nights. By 2007, the number of over-the-air games was down to approximately 20. MASN's broadcast partner switched from WDCA to WDCW for the 2009 - 2012 seasons. In 2013, WUSA became MASN's over-the-air broadcast partner for 20 Nationals games - all weekend games except for opening day.
Since the 2011 season, The Nationals' flagship radio station is WJFK-FM, "106.7 The Fan", which is owned and operated by CBS Radio. Most games will also be simulcast on WFED, "Federal News Radio" at 1500 and 820 AM, which is owned by Bonneville International and was the flagship station of the Nationals from the first season in Washington (2005) through the 2010 season. Whenever WFED can't air games due to conflicts, those games air on WJFK's sister station WJFK (1580 AM, "CBS Sports Radio 1580").
