[2] THR began its test transmission on the night of 31 August 1994 on FM 99.3 MHz from the Gunung Ulu Kali transmitter site covering the state of Selangor, Kuala Lumpur, and western Pahang.

On 9 September, at precisely 3:00 pm local time, symbolically in line with its '99.3' frequency THR officially came into being, operating in both Malay and English for 24 hours a day on the 80:20 formula - 80% broadcast time was in English, 20% in Malay; it was the second station in Malaysia to go round-the-clock after Klasik Nasional FM (then known as Radio 1) in 1971, and did so right out on the first day of its transmission.

[3] THR featured some of the best deejays in the local broadcasting industry such as flyguy, Richard La Faber, Gina, Andy Hakim, Daphne Nasir, Suzana, Deanna Nassem Rahman, Nasa, Rezz, Albert Ng, Sheela Haran, Kassandra Kassim, Glen Salay, and Simon D' Cruz.

A year later in 1995, THR expanded its broadcast coverage area to Negeri Sembilan, Melaka and Johor; its broadcast could also be heard in Singapore - at one point THR proved so popular in Singapore, stations there felt threatened by the alarming rate at which listeners changed to the station.

However, it was the start of AMP Radio Network's HITZ FM broadcast in January 1997 that really hurt the popularity of THR, as it did Best 104.

In 2002, THR expanded coverage to Kuantan, Kuala Terengganu and Kota Bharu, and Gegar was launched 24 hours as Malay East Coast radio station to compete against Manis FM.

[5][6][7][8] The station was eventually acquired by AMP Radio Networks (now Astro Radio) in 2005 and split into 2 different channels; the Tamil language section became THR Raaga and the Malay language section became THR Gegar, which broadcasts primarily on the East Coast region of Peninsular Malaysia.
