Although Kuala Lumpur is not located within Pahang state, but why is RTM Pahang FM 107.5MHz still available in Klang Valley?


In Kuala Lumpur and Klang Valley areas, RTM state radio stations are generally available with KL FM 97.2MHz and Selangor FM 100.9MHz, meanwhile Gunung Telapak Buruk transmitted Negeri Sembilan radio station Negeri FM 92.6MHz is weakly available in Kuala Lumpur, but Pahang FM is also receivable in Kuala Lumpur and Klang Valley.


Kuala Lumpur is the capital city of Malaysia, some people may ask why Pahang FM can be tuned in Kuala Lumpur, despite Kuala Lumpur is not located in Pahang state.


This is because RTM Pahang FM has a transmitter in Gunung Ulu Kali on the frequency 107.5MHz, but the main intended coverage is West Pahang such as Temerloh, Bentong, Karak, Chenor, Bera, Selancar, Keratong, and Lipis.


West Pahang areas highly relies on Gunung Ulu Kali radio transmitter because Bukit Pelindung, Bukit Senggora, Bukit Sulai and Bukit Istana transmitters cannot be received there. Gunung Ulu Kali is located in Genting Highlands, Pahang, it is a very strategic transmitter site in Central Region of Peninsular Malaysia. 


Gunung Ulu Kali transmitter mainly covers Kuala Lumpur and Selangor for most of the radio stations, but Pahang FM 107.5MHz does not target Kuala Lumpur and Selangor as it focuses only in West Pahang.


Although RTM Pahang FM 107.5MHz is available in Kuala Lumpur and Selangor, but the signal is not clear because its transmitting antenna in Gunung Ulu Kali beams signal towards east direction to cover West Pahang only with directional antenna. It is same as RTM Johor FM 105.3MHz in Gunung Ledang, despite Gunung Ledang transmitter covers Melaka and North Johor, but RTM Johor FM 105.3MHz covers only North Johor (Tangkak, Muar, Segamat and North Batu Pahat) with directional antenna by beaming signal towards south direction from Gunung Ledang, but it does not cover Melaka, so RTM Johor FM 105.3MHz has co-channel interference from Suria FM 105.3MHz Gunung Ulu Kali transmitter in most of Melaka areas.


According to Radio Televisyen Malaysia (RTM), Kuala Lumpur and Selangor are the bonus coverage of RTM Pahang FM 107.5MHz from Gunung Ulu Kali transmitter, despite these regions are not its intended coverage.


Some people even compare this with Best FM 104.1MHz in Kuala Lumpur. Best FM is a Malay language commercial radio station from Johor, then he or she asks whey RTM Johor FM does not expand coverage in Klang Valley like Best FM.


Same as Pahang FM, RTM Johor FM is a state public radio station from Radio Televisyen Malaysia serving Johor only. RTM Johor FM is not a commercial radio station like Best FM. If RTM does such way to expand coverage of Johor FM to Klang Valley, RTM wastes the transmission fees in non-targeting region, even it can cannibalize other radio stations' positions in Klang Valley, notably KL FM and Selangor FM. RTM restricts several state radio stations coverage with directional antenna to prevent cannibalization, so Selangor FM and Pahang FM have different radio reception in Klang Valley because they are using directional antenna in Gunung Ulu Kali to cover different areas.


Selangor FM 100.9MHz only covers Selangor and Kuala Lumpur, meanwhile Pahang FM 107.5MHz is only for West Pahang.


RTM operates 3 state radio stations in Gunung Ledang with directional antennas.

* Melaka FM 102.3MHz covers Melaka only

* Negeri FM 107.7MHz covers Gemas, Tampin, Gemencheh, Simpang Pertang and East Negeri Sembilan areas only.

* Johor FM 105.3MHz only covers North Johor


Although Best FM is a commercial radio station targeting Johor, but it is available in Kuala Lumpur and Selangor on 104.1MHz because it expanded the coverage there in 1996 to compete against THR FM (Time Highway Radio) where Best FM also carried English language programs. Until today, Best FM still broadcasts in Kuala Lumpur and Selangor, despite it mainly serves Johorean listeners, but it acts as the alternative radio station to the listeners in the regions, so commercially it can compete against Suria FM, Era, Hot FM, Sinar FM etc.
