Sitiawan is the most critical Perak areas to tune Minnal FM because none of its frequencies are clear and stable.

It is 27 years of Minnal FM Ipoh frequency 98.9MHz from Gunung Kledang suffers adjacent channel interference with 988 FM 98.8MHz from Gunung Ulu Kali in most of Perak areas, the interference is caused by poor frequency planning from MCMC (known as Malaysia Telecommunications Department) in 1996.

Listeners in Southern Perak such as Teluk Intan, Kampung Gajah, Langkap, Bidor, Tapah, Sungkai, Chenderiang, Temoh, Bagan Datuk and Pasir Salak can tune alternatively on 96.3MHz which is transmitted from Gunung Ulu Kali.

The most critical area to tune Minnal FM in Perak is Manjung district because there are no clear and stable frequencies tuned in several locations of that district. 

Here are the radio reception videos of Minnal FM 98.9MHz, 96.3MHz and 107.9MHz where I filmed in Manjung district of Perak by locations:

1. Sitiawan

2. Lumut

3. Pangkor Island

4. Changkat Keruing

5. Ayer Tawar

Radio reception of Minnal FM in Pantai Remis is not filmed because that location is covered by FM 107.9MHz from Bukit Larut.

Among the mentioned locations, Minnal FM 98.9MHz Gunung Kledang signal is only moderate to clear in Seri Manjung, Ayer Tawar, Pangkor and Changkat Keruing where 988 FM 98.8MHz Gunung Ulu Kali signal is weak there. Little interference is still heard when I tuned in Lumut, but more interference is heard in Sitiawan.

Between Lumut and Pangkor, Minnal FM 98.9MHz reception in Pangkor is more stable than Lumut.

First alternative frequency FM 96.3MHz Gunung Ulu Kali is clear in Ayer Tawar and Lumut, but interference with Sinar FM 96.4MHz Bukit Larut is detected in Pangkor, and Sitiawan.

Second alternative frequency FM 107.9MHz Bukit Larut is very weak in Sitiawan, Ayer Tawar, Lumut and Pangkor actually.

Sitiawan is the most critical town of Minnal FM radio reception because none of its frequencies are clear and stable. 

In Sitiawan,

1. 98.9MHz is interfered by 988 FM 98.8MHz from Gunung Ulu Kali like Teluk Intan, Bidor, Sungkai, and Langkap

2. 96.3MHz is interfered by Sinar FM 96.4MHz from Bukit Larut

3. 107.9MHz signal is very poor

No clear and stable alternative frequency is available in Sitiawan.

To solve the interference, I suggest RTM to change Minnal FM's Ipoh frequency from 98.9MHz to 99.0MHz when RTM will upgrade its FM radio transmitter system in Gunung Kledang in the near future. Hence, I send my radio reception report to RTM through email. I do hope MCMC will approve RTM to change Minnal FM Ipoh frequency.
