Instead of "interstate" to Gunung Ledang to launch transmitter, Pahang FM just only has to upgrade transmission system of Bukit Sembilan and change frequency

 

Previously I had proposed RTM Pahang FM to launch Gunung Ledang transmitter to cover Muadzam Shah and Southern Pahang and abolish Bukit Sembilan transmitter on FM 100.9MHz at 1kW transmitter power.

 

Looking back my old proposal from last year, now I have some new leads. In order to expand more coverage areas, Pahang FM can retain Bukit Sembilan transmitter by upgrading transmission system and changing frequency, rather than launching in Gunung Ledang.

 

My old proposal of launching Pahang FM in Gunung Ledang is not needed because existing Bukit Sembilan transmitter site is a strategic site to cover Muadzam Shah and Keratong, Pahang.

 

Based on Nautel RF toolkit that I generated, Bukit Sembilan transmission site can perfectly cover Muadzam Shah, Keratong, Bera Selatan, Selancar and Tembangau.

 

 

Interference from One FM 88.1MHz Gunung Ledang transmitter in Muadzam Shah, Pahang is not caused by transmitter site, but its main cause is the frequency problem because Pahang FM 88.0MHz is too closed with One FM 88.1MHz, causing interference there.

 

Between Gunung Ledang and Bukit Sembilan, for Pahang FM, Bukit Sembilan is more strategic than Gunung Ledang to cover Muadzam Shah, Keratong, FELDA Selancar, FELDA Bera Selatan, and FELDA Tembangau because Pahang FM is RTM state radio station to serve Pahang. Hence, suggestion of launching Pahang FM in Gunung Ledang to cover Muadzam Shah is less logic. If such proposal is considered, I believe more RTM state radio station will do same thing, like Negeri FM launches Gunung Ulu Kali transmitter to cover Nilai, Negeri Sembilan, then Perak FM launches Gunung Ulu Kali transmitter to cover Tanjung Malim.

In my opinion, if Pahang FM wants to reach more coverage areas (Keratong, Felda Selancar etc) via Bukit Sembilan transmitter clearly, Pahang FM needs to change frequency, and upgrade transmitter system.

Currently Pahang FM Bukit Sembilan transmitter runs only 0.1kW, so it needs to upgrade to a 0.5kW transmitter if wants to cover more areas. 

The interference issue will not be resolved if Pahang FM just upgrades Bukit Sembilan transmission system without changing frequency because One FM 88.1MHz Gunung Ledang still continues interfering Pahang FM 88.0MHz coverage in Muadzam Shah. Therefore, Pahang FM has to change frequency (proposed: 100.8MHz).

==Proposal of Pahang FM Bukit Sembilan transmission system and frequency change==

- Frequency: FM 100.8MHz

- Power: 0.5kW

- Antenna system: 4 bay array dipole antenna

- Coverage: Muadzam Shah, FELDA Keratong, FELDA Selancar, Pelawan, Felda Palong, and part of Segamat

==RF analysis==

100.4MHz: Ai FM Gunung Ledang

100.8MHz: Pahang FM Bukit Sembilan (500W)

<400kHz, OK>

100.6MHz: MY FM Gunung Telapak Burok

100.8MHz: Pahang FM Bukit Sembilan (500W)

<200kHz, OK>

100.8MHz: Pahang FM Bukit Sembilan (500W)

100.9MHz: Selangor FM Gunung Ulu Kali

<100kHz, OK>

100.8MHz: Pahang FM Bukit Sembilan (500W)

101.1MHz: MY FM Bukit Pelindung

<300kHz, OK>

Note: RTM radio stations from Gunung Ledang (Radio Klasik FM 93.6MHz, Nasional FM 96.6MHz, Traxx FM 97.4MHz, Ai FM 100.4MHz, Melaka FM 102.3MHz, Minnal FM 103.3MHz, Johor FM 105.3MHz and Negeri FM 107.7MHz) are very clear in Muadzam Shah, Pahang.

I hope RTM will consider this proposal, and launch the tender procurement of transmission system upgrade and frequency change for Pahang FM in the future.
