DZRH (666 kHz AM) is an news/talk radio station serving Mega Manila market. The station is owned by the Manila Broadcasting Company in the Philippines. The station's studio is located at CCP Complex in Pasay City, Philippines, while its transmitter is located at Brgy. Malanday, Valenzuela City. DZRH operates 24 hours a day, 7 days a week. (except on Sundays where it signs-off at midnight to 4 AM, and except Holy Week of each year where it signs-off at midnight of Maundy Thursday until 4 AM of Easter Sunday)

DZRH is the oldest radio station in the Philippines by the Kapisanan ng mga Brodkaster ng Pilipinas or KBP. It broadcasts nationwide through an array of relay stations, each with its own frequency, re-broadcasting the national feed from satellite.

DZRH can also be heard on the internet, with various interactive features; a live chatroom where listeners can feed comments to the station in real-time, two modes of VOIP that can be used to call the station and participate in open-line discussions, and an online discussion forum called "Damdaming Bayan Online".

Though it is one of the oldest radio stations in the Philippines,[citation needed] DZRH was not the first. The first radio station in the Philippines was the now defunct KZKZ, which began broadcasting from Manila in 1922.


The Heacock era[edit]

DZRH first went on air as KZRH on July 15, 1939, after being founded by Samuel Gaches, the owner of H. E. Heacock Company, a department store company based in Escolta, Binondo, Manila. DZRH, which was then broadcasting on the frequency of 650 kilocycles, became the fourth commercial radio station in the Philippines and years later, it bought KZRC (now DYRC) from Isaac Beck in Cebu City. KZRH's radio broadcasts centered on musical, variety shows, comedy skits and short newscasts. Jazz and ballads became standard fare.

During the war, the Japanese took over the stations and KZRH became PIAM for their propaganda.

The birth and expansion of DZRH[edit]

After World War II, three prominent businessmen, Maestro Frederico Elizalde and his brothers then-Ambassador JM Elizalde and Manuel Elizalde (also known as Don Manolo) took over KZRH and KZRC. With the help of station manager Bertrand Silen, KZRH re-established its operations, this time at the Insular Life Building in Plaza Cervantes, Manila. In June 1946, the Elizalde family established the new network as Manila Broadcasting Company.

KZRH returned to the airwaves under MBC on July 1, 1946, and first covering the live inauguration of President Manuel Roxas under its new republic. In 1948, after the international telecommunications conference in the U.S. where the Philippines changed its first letter to "D", KZRH changed its callsign to DZRH, and has been expanded to over 30 stations nationwide.

In 1949, DZRH began airing the first radio drama, Gulong ng Palad. Radio drama is one of the traditional history of Philippine radio before the rise of television industry. Although, radio drama continues until today (only Ito ang Palad Ko, one of the longest-running drama anthology series since 1973).

In 1972, when then-President Ferdinand Marcos declared Martial Law, DZRH was temporarily closed for a few months. It was the only other time in DZRH’s history, since World War II, that broadcast would be interrupted.

In 1977, DZRH moved from 650 kHz to the current frequency at 666 kHz due to allocation of frequency spacing for AM stations switched from 10 kHz to 9 kHz.

In 1979, DZRH launched Operation Tulong, a socio-civic organization that helps the people in time of need.

The country tuned in and listened as DZRH covered the Snap Elections of 1986, the EDSA Revolution, and the peaceful installation of President Cory Aquino as a result of People Power.

In 1989, DZRH celebrated its 50th golden anniversary by launching "50 Taon ng Radyo", a spectacular event happened on Sunday, July 23, 1989 with parades, games, events, concerts, ceremonies and anniversaries with fireworks display and indoor fireworks happened in Rizal Memorial Stadium and Araneta Coliseum.

In 1994, as part of their 55th anniversary, DZRH launched its own nationwide satellite radio broadcast by covering the whole country, reaching 97% of its communities. Thus, the slogan is "One Nation, One Station". It also bought some of the broadcast veterans such as Jay Sonza, Rey Langit and Ka Louie Beltran.

In 2009, DZRH celebrated its 70th anniversary by launching of the "Fiesta Sitenta".

In the final quarter of 2011, DZRH did changes in their programming line-up as well as the adoption of the new slogan "RH Agad!"

DZRH celebrated its 75th Diamond Jubillee Anniversary last July 15, 2014 at the Manila Hotel with the launching of the coffee-table book and the special commemorative stamp courtesy of PhilPost.

In 2015, DZRH celebrated its 76th anniversary with the theme "76 Taon ng Balita at Serbisyo".
