Since 2013, the Astros' flagship radio station is KBME, Sportstalk 790 AM (a Fox Sports Radio affiliate). Previously, the team had a partnership with KTRH (740 AM) which went from 1999 to 2012 (both stations are owned by iHeartMedia). This change suddenly made it difficult for listeners outside of Houston itself to hear the Astros, as KTRH runs 50 kilowatts of power day and night, and KBME runs only five kilowatts. As a result, KTRH is audible across much of Central, East, and South Texas, whereas KBME can only be heard in Houston, especially after dark. Milo Hamilton, a veteran voice who was on the call for Hank Aaron's 715th career home run in 1974, retired at the end of the 2012 season, after broadcasting play-by-play for the Astros since 1985. Dave Raymond and Brett Dolan shared play-by play duty for road games, while Raymond additionally worked as Hamilton's color analyst (while Hamilton called home games only for the past few seasons before his retirement); they were not retained and instead brought in Robert Ford and Steve Sparks to begin broadcasting for the 2013 season.
