Perak FM South Perak frequency changing suggestion and review




RTM Perak FM has two transmitters to cover South Perak where 95.6MHz Gunung Kledang reception is not clear, mainly FM 97.3MHz from Changkat Rembian and FM 89.6MHz Bukit Asa.

FM 97.3MHz Changkat Rembian for Tapah, Bidor, Chenderiang, Sungkai and Temoh. FM 89.6MHz from Bukit Asa for Tanjung Malim and Slim River.

Current FM 89.6MHz Bukit Asa covers Tanjung Malim and Slim River with low power transmission, but it is too close with BFM 89.9MHz from Gunung Ulu Kali.

FM 89.6MHz: Perak FM Bukit Asa
FM 89.9MHz: BFM 89.9 Gunung Ulu Kali
<300kHz, NOT OK>

FM 89.6MHz: Perak FM Bukit Asa
FM 89.7MHz: Ai FM Gunung Telapak Burok
<100kHz, OK>

In my opinion, there are no vacant frequencies for Ipoh by using Gunung Kledang. In order to free up a frequency for Ipoh new radio station, RTM Perak FM shall change its Bukit Asa frequency from 89.6MHz to other frequency. Talking about the frequency change, I would suggest FM 107.1MHz.

Besides that, in order to improve better reception of Perak FM in Tanjung Malim and other South Perak areas without using Gunung Ulu Kali. Perak FM shall use at least 1kW power to cover there.

==My suggested parameter for Perak FM Tanjung Malim frequency==
Frequency: FM 107.1MHz
Power: 1kW
Transmitter Site: Bukit Asa, Selangor.
Coverage areas: Tanjung Malim, Slim River, Terolak, and Behrang. Also accessible in Hulu Selangor areas such as Kuala Kubu Bharu, Kerling, Batang Kali, Serendah, Bukit Beruntung and Lembah Beringin.

==RF analysis of Perak FM Tanjung Malim frequency 107.1MHz==

106.7MHz: RTM Ai FM Gunung Ulu Kali
107.1MHz: RTM Perak FM Bukit Asa 1kW
<400kHz, OK>

107.1MHz: RTM Perak FM Bukit Asa 1kW
107.5MHz: RTM Pahang FM Gunung Ulu Kali
<400kHz, OK>

107.0MHz: Suria FM Gunung Telapak Burok
107.1MHz: RTM Perak FM Bukit Asa 1kW
<100kHz, OK>

107.1MHz: RTM Perak FM Bukit Asa 1kW

<0kHz, OK>

    1. 96.2 Gerik cannot be widened as 100kHz with 988 Gn Jerai 96.1, Perak FM supposes to add 1 more transmitter in Bukit Palong Baling for Pengkalan Hulu and Gerik, they shall close down 96.7 RTM Gerik transmitter. Bukit Palong (104.7MHz) can cover Hulu Perak
