im4u FM 107.9 MHz transmitter site

Malaysia's first youth radio station, im4u FM had been launched on 3rd March 2013 on 107.9 MHz, transmitted from Bukit Sungai Besi as trial transmission for few months. im4u FM 107.9 broadcasts in Malay language majority.

I knew this radio station since 4th March 2013 when the frequency 107.9MHz that I used for my mp3 modulator (changed to 106.0MHz, finally on 106.1MHz since May 2013) clash with im4u FM 107.9 while I was driving from IUKL to my home. Before im4u FM launched, this frequency is empty and had been used for my mp3 modulator before. 107.9 MHz was formerly used by Negeri FM (then used by Klasik Nasional since 2007) Seremban frequency which transmitter site was in RTM Seremban, then later Gunung Telapa Burok when Klasik Nasional took over the 107.9MHz. Klasik Nasional 107.9MHz was closed transmission since December 2009 while its original Negeri Sembilan frequency 87.9MHz was upgraded its transmission power.

Unfortunately IM4U FM 107.9 is transmitted from Bukit Sungai Besi, only can covers Kuala Lumpur area, some Selangor area (except northern parts) and parts of Negeri Sembilan.

List of Selangor areas can receive im4u FM 107.9:
- Kajang, Klang, Shah Alam, Petaling Jaya, Sepang, Seri Kembangan, Bangi, Ampang, Sungai Buloh, Subang Jaya, Cheras, Kelana Jaya, Puchong and parts of Rawang/Kuala Selangor.

Among all TV and radio stations in Klang Valley, majority they are transmitted from Gunung Ulu Kali, instead of Kuala Lumpur Tower and Bukit Sungai Besi. RTM launched another frequencies in early 1990's for their radio stations to cover Kuala Lumpur city clearly, along with Gunung Ulu Kali frequencies.

If im4u FM locates its transmitter site in Gunung Ulu Kali or Bukit Cincin on 107.9 MHz, the Klang Valley area, even South Perak, Negeri Sembilan, West Pahang and parts of Malacca can receive im4u FM loudly and clearly on 107.9MHz. Gunung Ulu Kali transmitter can transmit up to Tapah, Rembau, Malacca (Masjid Tanah), Maran, Bahau, Johol, Temerloh, Seri Iskandar and Manjung. At the same time, the northern parts of Selangor (Rawang to Hulu Selangor and Sabak Bernam) can receive this radio station.

Before im4u FM launched, the 107.9 MHz was Minnal FM from Bukit Larut, Taiping, can be received in South Perak (not so clear). If im4u FM transmitted from Bukit Cincin on 107.9MHz, the coverage of Minnal FM Bukit Larut 107.9MHz will be minimized, somehow Teluk Intan, Kg. Gajah, Bidor, Sungkai, Sitiawan, Manjung, and Seri Iskandar may not receive Minnal FM 107.9MHz from Bukit Larut anymore, instead receive im4u FM from Bukit Cincin, but Minnal FM listeners still can tune to 98.9MHz from Ipoh (Gunung Kledang), 96.3MHz from Ulu Kali or weaker 104.3MHz from Cameron Highlands (Gunung Brinchang).
