Coverage simulation anaylsis: Can Lojing receive Kelantan FM if transmitted from Gunung Brinchang?

Kelantan FM is RTM state radio station for Kelantan state. As today, Kelantan FM already reaches 85% of coverage areas in Kelantan with 6 frequencies below:

- 102.9MHz Wakaf Che Yeh for Kota Bharu

- 97.3MHz Bukit Bakar for Central Kelantan (Machang)

- 90.0MHz Bukit Tangki Air for Jeli

- 107.1MHz Bukit Bintang for East Kelantan 

- 92.0MHz Bukit Chupak for Gua Musang

- 88.1MHz Felda Paloh for Paloh

One district in Kelantan where is not covered by Kelantan FM with existing transmitters, namely Lojing. 

Lojing is the most difficult Kelantan location for installing a gap filler FM transmitter for Kelantan FM because it is an ultra remote location where fully covered by high mountains and terrains. This causes radio signal cannot be received in Lojing regardless any transmitter sites. For your information, Lojing is located in southwest Kelantan, a location between Gua Musang and Cameron Highlands. When you travel from Gua Musang to Cameron Highlands, you will pass through Lojing.

Kelantan FM is not receivable in Lojing with 6 existing frequencies. So, by adding transmitter in Gunung Brinchang, Cameron Highlands to cover Lojing, is Kelantan FM receivable in Lojing?

==Kelantan FM suggested parameter for Lojing==

* Frequency: FM 105.9MHz

* Power: 1kW

* Transmission site: Gunung Brinchang,  Cameron Highlands, Pahang

* Target location: Lojing, Kelantan

* Antenna direction: Northeast with directional antenna

==RF analysis==

105.9MHz: Kelantan FM Gunung Brinchang

106.1MHz: Ai FM Bukit Larut

<200kHz, OK>

105.7MHz: Lite FM Gunung Ulu Kali

105.9MHz: Kelantan FM Gunung Brinchang

<200kHz, OK>

According the coverage simulation map of Kelantan FM 105.9MHz from Gunung Brinchang for Lojing, only areas located nearby Pahang border will receive Kelantan FM. The coverage simulation map above is based on 10m receiving antenna. Overall, Lojing is still unable to receive Kelantan FM 105.9MHz from Gunung Brinchang. If RTM Kelantan FM installs transmitter in Gunung Brinchang, the listeners in Lojing still cannot receive Kelantan FM clearly. In addition, technically Kelantan FM is totally nothing signal from Gunung Brinchang in Lojing if use cheaper radio receiver unit where the receiver with shorter receiver antenna height.

In conclusion, Lojing cannot receive Kelantan FM if it has Gunung Brinchang transmitter. So, in order to cover Lojing clearly, RTM or transmission tower provider company shall do a site survey to find out suitable sites to cover Lojing, Kelantan. Unfortunately, currently there is no suitable transmitting location to cover Lojing, regardless any cellular tower within Lojing or not.

==Findings==

- Result: No signal in Lojing Highlands from Gunung Brinchang
