The Orang Asli radio station, Asyik FM currently has no Negeri Sembilan tuning frequency, however it relies on FM 102.5MHz Gunung Ulu Kali, FM 91.1MHz Kuala Lumpur Tower and FM 95.6MHz Gunung Ledang in part of Negeri Sembilan.
Asyik FM can be tuned in part of Negeri Sembilan via existing transmitters by following locations below:
1. FM 102.5MHz Gunung Ulu Kali: Mantin, Labu, Simpang Pertang, Port Dickson, Lenggeng, Linggi, and part of Seremban
2. FM 91.1MHz Kuala Lumpur Tower: Nilai
3. FM 95.6MHz Gunung Ledang (low power transmission): Gemencheh, Rompin and part of Jempol
In fact, there are many Orang Asli villages in Negeri Sembilan. The Orang Asli villages are mostly located in Jelebu, Kuala Pilah, Jempol and East Seremban districts. These areas can't receive Asyik FM via existing frequencies. Therefore, Asyik FM needs to set up a transmitter (0.25kW is sufficient) in Gunung Telapak Burok to cover Orang Asli areas in Negeri Sembilan, mainly districts in Kuala Pilah, Jelebu and Seremban.
The frequency availability in Gunung Telapak Burok is getting limited nowadays which cause Asyik FM or other radio broadcasters getting more difficult to get the new frequencies. Coincidentally, I notice FM 95.5MHz is also an empty frequency in Seremban and Jelebu. So, FM 95.5MHz becomes proposed frequency for Asyik FM's Gunung Telapak Burok transmission.
==Proposed transmission parameter for Asyik FM in Negeri Sembilan==
* Frequency: FM 95.5MHz
* Power: 0.25kW
* Transmitter site: Gunung Telapak Burok, Negeri Sembilan
* Antenna height: (same with other RTM radio stations)
* Antenna gain: 6.0dBd (3 bay array dipole antenna, each bay 2.0dBd)
* Antenna model: SIRA FM-04 or equivalent
* Antenna beaming angle: 30 DEG
==Radio frequency analysis between RTM Asyik FM 95.5MHz (Gunung Telapak Burok) and adjacent stations==
95.3MHz: Nasional FM Gunung Ulu Kali
95.5MHz: Asyik FM Gunung Telapak Burok (0.25kW)
<200kHz, OK>
95.4MHz: MY FM Gunung Pulai
95.5MHz: Asyik FM Gunung Telapak Burok (0.25kW)
<100kHz, OK>
95.5MHz: Pahang FM Bukit Sulai
95.5MHz: Asyik FM Gunung Telapak Burok (0.25kW)
<0kHz, OK>
95.5MHz: Asyik FM Gunung Telapak Burok (0.25kW)
95.6MHz: Asyik FM Gunung Ledang (0.25kW)
<100kHz, AFN- Adjacent Frequency Network>
95.5MHz: Asyik FM Gunung Telapak Burok (0.25kW)
95.7MHz: Negeri FM Bukit Tampin
<200kHz, OK>
95.5MHz: Asyik FM Gunung Telapak Burok (0.25kW)
95.8MHz: Fly FM Gunung Ulu Kali
<300kHz, OK>
Based on RF analysis, the transmission of Asyik FM 95.5MHz from Gunung Telapak Burok will not cause any interference to existing radio stations' coverage because proposed parameter for Asyik FM is just low power transmitter as much 0.25kW.
In North Johor, Asyik FM is on 95.6MHz from Gunung Ledang, main targeting coverage is Chaah, Labis and Bekok in Segamat district, transmitter power is 0.25kW. The proposed frequency FM 95.5MHz from Gunung Telapak Burok will not cause interference to Asyik FM 95.6MHz coverage because both are using low power transmitters. Despite Asyik FM 95.5MHz and 95.6MHz will have interference each other in Jempol, Negeri Sembilan, but it is not an issue because both are same radio stations, so it is considered as self-interference and AFN (adjacent frequency network), listeners can tune vice-versa with 100kHz frequency step.
In addition, Asyik FM 95.5MHz Gunung Telapak Burok will not cause interference to Pahang FM 95.5MHz Bukit Sulai and Negeri FM 95.7MHz Bukit Tampin due to different coverage areas and antenna configuration. Negeri FM 95.7MHz from Bukit Tampin covers only Tampin, Rembau and Kota, but proposed Asyik FM 95.5MHz Gunung Telapak Burok does not cover Rembau. Pahang FM 95.5MHz Bukit Sulai covers only Gambang and Pekan where Kuantan frequency FM 104.1MHz from Bukit Pelindung has co-channel interference with Best FM 104.1MHz from Gunung Ulu Kali.
Gunung Telapak Burok radio transmission will not overspill to Gambang and Pekan (Chini).
I also sketch the antenna pattern map for Asyik FM 95.5MHz Gunung Telapak Burok transmission, based on SIRA FM-04 dipole antenna and FM-07 Yagi antenna diagram, the drawings above are going to be sent to RTM engineering and planning team via email as the proposal.
SIRA FM-07 in different angle at 30DEG and 60DEG, meanwhile SIRA FM-04 is at 30DEG.
Among all 3 antenna pattern drawings, SIRA FM-04 at 30DEG is the best because Asyik FM reach more coverage in Negeri Sembilan on FM 95.5MHz from Gunung Telapak Burok, compare to SIRA FM-07 drawings.
To avoid interference to the existing adjacent stations, SIRA FM-07 at 60DEG angle drawing is proposed.
Although I think SIRA FM-04 at 30DEG antenna pattern drawing is the best for Asyik FM 95.5MHz Gunung Telapak Burok transmission, but I send all the drawings to RTM via email as the proposal, so the engineering team can evaluate the proposed antenna pattern.
The proposal was actually made in March 2019 (a month before I joined the broadcast transmitter equipment company).
I hope RTM will consider this proposal, so Asyik FM can reach Negeri Sembilan via FM frequency transmission.
