DWRX (93.1 FM), broadcasting as Monster RX 93.1 (also known as Monster Radio RX 93.1), is a commercial radio station based in Metro Manila, airing 24 hours a day with a contemporary hit radio musical format. It is owned and operated by Audiovisual Communicators, Inc. The station's studio and transmitter are located at the 17th floor of Strata 2000 Bldg., F. Ortigas, Jr. Road (formerly Emerald Avenue), Ortigas Center, Pasig City.

From 1983 to 1993, it was known as RX93.


The station was previously known by its call letters DWEI, originally owned by Liberty Broadcasting Corporation which featured MOR (aka Beautiful music) programming. However LBC sold the station to Audiovisual Communicators then led by Rene Lacson and Freddie Garcia. The station was relaunched as DWRX-FM on August 23, 1983. However, the station had inherited the call letters “RX” from the station’s former owners, RX referring to "prescription music". On that same year, the station adopted the pop format as Music City RX93 and became #1 in radio surveys in the mid-1980s.

In 1987, the station transferred from its studio and offices in Makati to its current location in Ortigas, and it was reformatted as Light Rock RX93, carrying a light rock format.

In October 1990, the station reverted to its pop format as Monster Radio RX93. Three years later, it carried the slogan "The First Creative Pop Station" and added the point .1 to its call number, becoming Monster Radio RX 93.1. In the late Nineties, it adopted its current slogan, "Manila's Hottest". The station is also known as "Summer's Hottest" & "Season's Hottest".

Monster Scholarship Program

This project began in September 2009. It started as a small effort by Monster Radio RX93.1's Vice-President for Operations & Programming, Raffy Barreiro, to help college students in dire need of assistance. The scholarship provides assistance for one semester and does not require a student to maintain a certain average.[1]


The station has been named Best FM Radio Station a record (11) times by the Kapisanan ng mga Brodkaster ng Pilipinas, most recently in the 25nd KBP Golden Dove Awards (2017).

In addition, several RX programs and specials, as well as on-air radio personalities, have been recognized by the KBP, the Catholic Mass Media Awards (CMMA), and other award-giving organizations.
