Recently I suddenly think if RTM Pahang FM launches Gunung Ledang transmitter for Southwest Pahang.
In West Pahang areas such as Bentong, Bera, Temerloh, Kuala Lipis, Pahang FM tuning frequency is 107.5MHz from Gunung Ulu Kali, meanwhile Raub receives 102.2MHz from Fraser's Hill.
Keratong still receives Pahang FM either 107.5MHz from Gunung Ulu Kali or 88.0MHz Bukit Sembilan, but it could be likely less clear there because interference from Gunung Ledang.
Although Pahang FM 107.5MHz Gunung Ulu Kali has 200kHz frequency separation from Melody FM 107.3MHz Gunung Ledang and Negeri FM 107.7MHz Gunung Ledang, but it sounds ok because they're far enough. However, it has interference from Gunung Ledang when comes to Tembangau, Keratong, Bera Selatan and Kota Shah Bandar.
For FM 88.0MHz Bukit Sembilan, it may be likely having interference from One FM 88.1MHz Gunung Ledang in Keratong, the interference can be worse when comes to Keratong areas where just next to Johor border. In fact, Pahang FM 88.0MHz Bukit Sembilan operation is much earlier than One FM 88.1MHz Gunung Ledang.
To cover large part of Southern Pahang, Gunung Ledang is the strategic location. If Pahang FM launches in Gunung Ledang to cover southwestern Pahang mainly Keratong, Felda Bera Selatan, Felda Tembangau and Kota Shah Bandar, its coverage is more strategic than FM 88.0MHz Bukit Sembilan because it generates more coverage population due to higher elevation of the site.
In terms of frequency, FM 100.9MHz is most suitable and ideal one currently.
==Pahang FM Gunung Ledang parameter suggestion==
* Frequency: FM 100.9MHz
* Power: 1kW
* Transmitter site: Gunung Ledang, Johor
* Coverage: Keratong, Muadzam Shah, Kota Shahbandar, Felda Tembangau, Felda Bera Selatan
==RF analysis==
100.9MHz: Selangor Gunung Ulu Kali
100.9MHz: Pahang FM Gunung Ledang
<0kHz, OK>
100.9MHz: Pahang FM Gunung Ledang
101.1MHz: Minnal FM Gunung Pulai
<200kHz, OK>
100.9MHz: Pahang FM Gunung Ledang
101.1MHz: MY FM Bukit Pelindung
<200kHz, OK>
100.6MHz: MY FM Gunung Telapak Burok
100.9MHz: Pahang FM Gunung Ledang
<300kHz, OK>
If RTM adds Pahang FM 100.9MHz Gunung Ledang, here's the result:
1. Keratong, Muadzam Shah, Felda Tembangau, and Felda Bera Selatan listeners can receive Pahang FM on 100.9MHz from Gunung Ledang, clearer than FM 107.5MHz Gunung Ulu Kali (for Tembangau) and FM 88.0MHz Bukit Sembilan (for Keratong).
2. RTM will have ten radio transmitters in Gunung Ledang, Johor.
3. Benefits to Pahang FM's listeners who often travel to state borders from Pahang. Example:
* Felda Tembangau (Pahang) to Felda Serting Hilir (Negeri Sembilan)
* Felda Keratong (Pahang) to Felda Palong (Negeri Sembilan)
* Felda Selancar (Pahang) to Segamat/Labis (Johor)
4. Pahang areas where nearby Johor Segamat border can receive Pahang FM clearly from Gunung Ledang, this will solve interference between FM 88.0MHz Bukit Sembilan and One FM 88.1MHz Gunung Ledang.
5. Segamat, Gemas, Rompin, Felda Palong, Felda Serting Hilir and Bandar Seri Jempol can receive Pahang FM 100.9MHz from Gunung Ledang, despite they're not the main coverage and under Pahang states.
6. Currently all Pahang FM transmitters are located within Pahang state, so it breaks its history by "crossing" to Johor border and launching transmitter in Gunung Ledang.
For RF analysis, Pahang FM 100.9MHz Gunung Ledang transmission will not have co-channel interference with Selangor FM 100.9MHz in Melaka and Port Dickson, Negeri Sembilan because Pahang FM only beams to southwest Pahang from Gunung Ledang (northeast direction from site). The only CCI locations can be likely in Teriang, and Bandar Bera.
Since it covers only southwest Pahang, it does not mean Pahang FM 100.9MHz Gunung Ledang will be available in Johor (Muar, Batu Pahat, Tangkak), Melaka and Negeri Sembilan (Tampin, Gemencheh, Rembau and Port Dickson) due to antenna direction.
While RTM has Pahang FM 100.9MHz in Gunung Ledang, RTM Pahang FM can maintain FM 88.0MHz Bukit Sembilan frequency for Muadzam Shah as gap filler transmitter to cover blind spot of FM 100.9MHz Gunung Ledang.
For listeners who from Kemayan/Teriang/Bandar Bera travel to Keratong/Tembangau/Selancar via Felda Lui and Jalan Bahau-Keratong road, they can switch to FM 100.9MHz from Gunung Ledang loudly and clearly when the reception of FM 107.5MHz Gunung Ulu Kali is weak while on the journey to those locations.
Besides that, listeners in Keratong, FELDA Bera Selatan, Felda Tembangau can also tune to 100.9MHz if Pahang FM 107.5MHz Gunung Ulu Kali is interfered by Melody FM 107.3MHz and Negeri FM 107.7MHz from Gunung Ledang.
I may realize that Pahang FM 88.0MHz from Bukit Sembilan may have interference from One FM 88.1MHz Gunung Ledang in FELDA Selancar, Keratong where not far from Johor border. With Gunung Ledang transmitter FM 100.9MHz, listeners in those locations can listen to Pahang FM on the frequency clearly.
As a result, RTM Gunung Ledang can have four state radio stations for different target locations, such as:
1. Johor FM 105.3MHz for North Johor
2. Melaka FM 102.3MHz for Melaka
3. Negeri FM 107.7MHz for East Negeri Sembilan such as Gemas, Felda Lui, Felda Palong, Gemencheh & Simpang Pertang
4. Pahang FM 100.9MHz for Southwest Pahang such as Keratong, Felda Tembangau and Muadzam Shah (proposal)
RTM can consider this suggestion if there is necessary.
