DYHP, dubbed as The Sound of the City, commenced its operations on September 13, 1963 Cebu under the auspices of the Philippine Herald newspaper and Inter-Island Broadcasting Corporation. It was the second RMN station established in Visayas with DYRI in Iloilo as its first. The station was then broadcasting on the frequency of 600 kHz and became the fourth commercial radio station in the city. During the existence, the station's studio was located along Legazpi cor.

Its first radio drama was Kun Ako Ang Pasultihon ("Kung Ako Ay Ikukuwento"/"If I Were To Be Told"), a comedy drama written and directed by radio personality and Cebu Provincial Board Member Julian "Teban" Daan. The drama talks about ordinary problems of ordinary people to which Daan and Priscilla Raganas, RMN's premiere leading lady gets to pitch in their advices as ordinary people.

On September 21, 1972, when then-President Ferdinand Marcos declared Martial Law from the issuance of Proclamation 1081, DYHP was among the casualties. Several years later, the station returned to the airwaves as Ang Radyo Natin, taken from Manila's DZXL. Its success led to the opening of sister station DYHP-FM in 1976.

On November 23, 1978, following the switch from the NARBA-mandated 10 kHz to the adoption of the 9 kHz spacing implemented by the Geneva Frequency Plan of 1975 on AM radio stations in the Philippines and across the Asia-Pacific region, DYHP assigned its current frequency to 612 kHz

After a series of radio surveys in the city, DYHP became one of the most popular AM radio station in the entire province of Cebu.

During the early 1990s, DYHP began simulcasting some of its programs via satellite thru its stations and affiliates in Visayas and Northern Mindanao.

In 1993, the station transferred its studios to Gold Palace Bldg. along Osmeña Blvd.

On March 2, 2009, as part of its nationwide expansion, RMN's AM stations started carrying the Radyo Mo Nationwide branding. During its relaunch, RMN was released a new corporate station ID and a jingle entitled, "Tatak RMN", sung by Wency Cornejo. At the same time, the station's transmitter facilities moved to its new transmitter site in White Road, Brgy. Inayawan for better signal reception.

Martinez Bldg. along Osmeña Blvd. to adjust to modern broadcast settings.

In June 2014, DYHP began simulcasting CCTN-47's afternoon local newscast Sayri 47. In 2015, DYHP started airing a drama entitled, "Sabungera". Radio drama was about a person who was adopted by a certain man. As the person grew up, they became fond and grew successful with cockfighting. Not long after, the person knew that one of the competitors was his biological father.
