WTVB

WTVB, AM 1590, is a regional radio station located in Coldwater, Michigan. It carries largely oldies music and local news and sports, with the ABC Radio Network as its source for national news, and carries Cumulus Media's "Greatest Mojo" oldies format. Midwest Communications owns WTVB-AM.

The call letters originally stood for Twin Valley Broadcasting and are in no way connected to any television station, although the station bills itself as "The Voice of Branch County. The "valleys" mentioned (ironically Coldwater is in one of the highest parts of southern Lower Michigan) are apparently the short Coldwater River and the St. Joseph River in south-central Michigan.

WNWN-FM Radio (FM 98.5) "WIN 98-5," licensed to Coldwater and now a country music station primarily targeting the Battle Creek and Kalamazoo areas, was originally WTVB-FM at 98.3, the FM signal that duplicated WTVB when FM radio was new. Like most AM radio stations, WTVB's signal is drastically weakened at night and does endure severe interference during thunderstorms.

WTVB was previously known as 16/TVB for a time. Even 10+ years after that campaign was stopped, and WTVB was officially known as AM 1590 WTVB, local community members have been known to refer to the station as 16/TVB.
