WFID

WFID (95.7 FM), branded on-air as Fidelity, is a radio station licensed to serve Río Piedras, Puerto Rico, established in 1958.

The founders, Rafael Acosta and his wife Victoria Suarez, made their first broadcast from their house with a 250W FM transmitter on November 17, 1958 before hiring others.

Acosta frequently travelled to the United States to stay up to date with technology, particularly the Gates transmitters and equipment.

As of 2015[update] the 50,000-watt WFID was owned and operated by Arso Radio Corporation under Jesús Soto, who had been a friend of Acosta's.

WFID was the first FM radio station to broadcast salsa in stereo, Saturday nights on their program "El Bailable Don Q".
