RTM Asyik FM can launch a transmitter in Gunung Kledang to cover Orang Asli areas in Central Perak (Ipoh, Gopeng, Kampar), and Lojing Highlands, Kelantan. Proposed frequency: FM 107.4MHz.

 

In Perak, RTM Asyik FM has only a transmitter, FM 93.1MHz from Bukit Ladang Teh, just covers Lenggong, meanwhile listeners other Perak areas rely on FM 105.1MHz from Cameron Highlands and FM 102.5MHz from Gunung Ulu Kali, but reception of both frequencies are not clear.

 

There are many Orang Asli in Central Perak, such as Gopeng, Kampar, Kampung Kepayang, Langkap, Sungai Siput (U), and Ulu Kinta, however these locations cannot receive Asyik FM via frequency transmission. Although FM 105.1MHz from Cameron Highlands can be received partially there, but reception is very poor. 

 

In my opinion, RTM Asyik FM can launch Ipoh frequency (Gunung Kledang) to cover Orang Asli areas in Central Perak. 

 

==Proposed parameter of Asyik FM Ipoh frequency==

- Frequency: FM 107.4MHz

- Power: 0.5kW

- Transmission site: Gunung Kledang, Ipoh, Perak

- Antenna type: Directional Dipole

- Targeting areas: Ipoh, Chemor, Sungai Siput (U), Gopeng, Tanjung Rambutan, Teronoh, Kampar, Batu Gajah, Simpang Pulai, Temoh, Kampung Kepayang, Ulu Kinta, Chenderiang (partly), Tapah (partly), Bidor (partly) and Lojing Highlands (partly)

- Antenna beaming angle: 75DEG


==RF analysis==

107.1MHz: Nasional FM Bukit Larut

107.4MHz: Asyik FM Gunung Kledang 

<300kHz, OK>


107.2MHz: Kelantan FM Dabong

107.4MHz: Asyik FM Gunung Kledang

<200kHz, OK>


107.4MHz: Asyik FM Gunung Kledang

107.5MHz: Pahang FM Gunung Ulu Kali (West Pahang only)

<100kHz, OK>


107.4MHz: Asyik FM Gunung Kledang

107.6MHz: goXUAN FM Bukit Penara

<200kHz, OK>

 

Based on RF analysis above, usage of the frequency FM 107.4MHz in Gunung Kledang by Asyik FM doesn't likely cause the interference to existing radio stations as the proposed parameter is low power transmission, rather than 2kW power like other RTM radio station. 

 

Besides that, Asyik FM 107.4MHz Gunung Kledang transmission will not cause interference to Pahang FM 107.5MHz Gunung Ulu Kali coverage in West Pahang (Bentong, Lipis, Temerloh, Bera and Chenor). Although the interference between Asyik FM 107.4MHz and Pahang FM 107.5MHz happens in Southern Perak areas like Bidor, Sungkai, Teluk Intan, Langkap, and Kampung Gajah, but Pahang FM 107.5MHz is not affected because South Perak is not its service coverage as Pahang FM 107.5MHz targets only West Pahang areas.

 

Compare with the interference between 988 FM 98.8MHz from Gunung Ulu Kali and Minnal FM 98.9MHz Gunung Kledang, the interference between Asyik FM 107.4MHz (Gunung Kledang) and Pahang FM 107.5MHz (Gunung Ulu Kali) is lesser because Pahang FM 107.5MHz doesn't beam to Perak direction much like Traxx FM 100.1MHz as Pahang FM is using directional antenna (likely Yagi type). 

 



With Asyik FM Ipoh frequency 107.4MHz from Gunung Kledang, the radio station is expected to become receivable in part of Lojing Highlands, Kelantan as proposal antenna pattern diagram is beaming to northeast direction at 75DEG angle. Lojing Highlands has many Orang Asli people, the reception of Asyik FM 105.1MHz from Gunung Brinchang is unstable there due to interference with Molek FM 105.1MHz from Kota Bharu (Peringat). If Asyik FM Ipoh frequency 107.4MHz is launched, I may predict that the signal reception of FM 107.4MHz is slightly better than FM 105.1MHz in Lojing Highlands. 

 

Orang Asli villages in South Perak like Tapah, Chenderiang and Bidor can receive Asyik FM 107.4MHz from Gunung Kledang. Although it is less clear, but at least it is clearer than 105.1 and 102.5. For the interference, Asyik FM 107.4MHz may dominate the signal more than Pahang FM 107.5MHz. If Asyik FM 107.4MHz signal is moderate in Bidor and Tapah, so it is unnecessary to launch Tapah frequency from Changkat Rembian.

 

Next, Orang Asli villages in Sungai Siput (U) are expected to receive Asyik FM 107.4MHz from Gunung Kledang, signal is likely better than FM 93.1MHz from Bukit Ladang Teh which covers Lenggong. Despite Asyik FM 107.4MHz Gunung Kledang reception in less clear in Sungai Siput (U) town, but the main targeting areas are actually the Orang Asli villages. Therefore, it is not necessary to launch a repeater in Sungai Siput (U) town like Nasional FM 89.5MHz and Radio Klasik FM 90.7MHz.

 

For Gopeng, the town in Kinta district has many Orang Asli villages also. Asyik FM signal is expected to be clearer in Gopeng with the launch of Gunung Kledang transmitter FM 107.4MHz, the listeners will receive clearer signal than 105.1MHz from Gunung Brinchang.
