WMVX (1570 AM; "Nossa Rádio 1570") is a radio station licensed to Methuen, Massachusetts, USA. The station is owned by Costa-Eagle Radio Ventures Limited Partnership, a partnership between Pat Costa and his chief investor, The Eagle-Tribune. WMVX broadcasts in Brazilian Portuguese and airs ethnic programming provided by the ICGG Television and Radio. The station is branded as "Nossa Rádio 1570", with "Nossa" translated as "Wow."
The station has been known by the call letters WMLO, WBVD, and WNSH. Its studios have been located in Danvers, in Salem (at Pickering Wharf), and on the second floor of a hardware warehouse in Hamilton. In 2011, Willow Farm, Inc. sold WNSH for $400,000 to Costa-Eagle Broadcasting. In March 2011, Costa-Eagle changed the station to "Viva 1570". The format changed from tropical music, simulcasting Costa-Eagle sister station WNNW, to Spanish Adult Contemporary. On November 26, 2012, the call letters were changed to WMVX. The station switched to its Brazilian Portuguese ethnic format in July 2014. On October 8, 2014, the New England Revolution announced that WMVX would become the team's Portuguese-language flagship station.
In January 2013, WMVX was granted a U.S. Federal Communications Commission (FCC) construction permit to increase day power to 50,000 watts. The station recently switched its city of license from Beverly, Massachusetts to Methuen, MA with its transmitter in Andover, Massachusetts. Even with the anticipated increase to 50,000 watts, the maximum AM power allowed by the FCC, the station must still reduce power at night to 102 watts because 1570 kHz is a Mexican clear channel frequency and WMVX must protect XERF in Ciudad Acuña, Coahuila, Mexico, the Class A station on 1570.
