Rádio WCMN-FM

WCMN-FM (107.3 FM) is a radio station broadcasting a contemporary hit radio format. Licensed to Arecibo, Puerto Rico, it serves the Puerto Rico area. The station is currently owned by Uno Radio Group.

WCMN-FM was the first FM radio station to be licensed on the north of Puerto Rico. During most of its history it was called "Delta 107". In February 2004, WCMN-FM was acquired by "Uno Radio Group". In May 2004, WCMN-FM changed its brand name from "107.3 Delta" to just "107.3" and added the "Toca De To" slogan which eventually became the new brand name.

In March 2007, Uno Radio Group officially acquired WMIO from Bestov Broadcasting (previously known as Audioactiva 102.3 FM) and chained it with WCMN-FM.

On January 9, 2009, MSG Radio Inc. acquired WIAC-FM and the Toca De To' brand moved to 102.5 FM on January 16, 2009. Old Toca De To stations WCMN-FM 107.3 and WMIO 102.3 continue as "107.3 Mi Emisora" and not chained to WIAC-FM.
