Perak FM in Gerik, Pengkalan Hulu, Klian Intan and Hulu Perak

The frequencies of Perak FM in Hulu Perak district are 94.2MHz from Lenggong, 96.1MHz from Gerik, meanwhile other Hulu Perak areas receive on 104.1MHz from Bukit Larut, Taiping, but there has weaker reception of Perak FM in Klian Intan, Pengkalan Hulu and Northeast parts of Hulu Perak areas, it may be received via MW 657kHz from Gerik with 20kW power and weaker transmitter 96.2MHz from RTM Gerik. This radio station also can be received in some parts of Thailand area (Betong).

The Perak FM Gerik frequency, 96.1MHz clash with 988 96.1MHz from Gunung Jerai after Gerik (to Klian Intan) due to same frequency (co-interference), the transmitter power of 988 96.1MHz is 10000 watts (equal to 10kW), which can cover whole Kedah, Perlis, Langkawi, Penang and some parts of North Perak (may include Hulu Perak).

RTM Perak FM 96.2MHz from Gerik has only 0.1kW (100W) transmitter power, which only can cover Gerik, meanwhile 96.1MHz in other area than Gerik (Klian Intan, Pengkalan Hulu) receive 988 from Gunung Jerai. 

Recently I find that Perak FM may have been shifted its Gerik frequency to 96.2MHz on MCMC/SKMM website. Here's the link: http://www.skmm.gov.my/Legal/Registers/Register-Of-Apparatus-Assignments-Search.aspx?src=rtm%20gerik&fld=Location&type=AABroadcast

96.2MHz is still clashed with 988 96.1MHz in Klian Intan and Pengkalan Hulu, even after Gerik, but interference may be reduced about 20-30%.

RTM Perak FM Gerik frequencies should put 95.9MHz, so the interference with 988 96.1MHz may be reduced 50% and above because the frequency distance between them is 0.2MHz. Although if Perak FM place Gerik frequency on 95.9MHz for Gerik, Pengkalan Hulu, and Klian Intan, the reception of two radio station may be same.

988 can be received in Gerik on 96.1MHz, but not clear, although if Perak FM uses 95.9MHz. Meanwhile, Perak FM 95.9MHz still can be received in Klian Intan and Pengkalan Hulu, but average signal.

In other cases, if RTM Perak FM wants to cover Pengkalan Hulu, and Klian Intan on FM frequencies, they should change their Gerik frequency to 95.9MHz and increase their transmitter power which can cover those areas (1-2 kW). 

Normally TV and radio stations in Klian Intan and Pengkalan Hulu are received from Baling, Kedah or Gunung Jerai.


If Perak FM used high power transmitter for Gerik area and 95.9MHz, Pengkalan Hulu and Klian Intan and some parts of Northeast Hulu Perak district can receive Perak FM signal from Gerik, but may weak.

Review on Perak FM Tanjung Malim and Slim River reception

Perak FM is a Malay language radio station for Perak states, which is owned by RTM (Radio Televisyen Malaysia).

The Perak FM frequencies in South Perak, mainly are 97.3MHz from Changkat Rembian, and 89.6MHz from Bukit Asa. In South Perak, Perak FM 95.6 from Gunung Kledang, Ipoh is still can be received in certain area of South Perak, but not so clear.

Perak FM 97.3MHz from Changkat Rembian, covers Tapah, Bidor, Sungkai, and Trolak, meanwhile 89.6MHz from Bukit Asa, covers only Slim River and Tanjung Malim.

In Slim River, Trolak and Tanjung Malim, I find that radio stations reception quality which transmitted from Gunung Ulu Kali (Genting Highlands) is much better than local transmitter in South Perak such as Bukit Asa.

Perak FM 89.6MHz (from Bukit Asa) is low power transmitter, it only covers 25km area from Bukit Asa (up to Slim River), its reception is not so good in some certain areas of Slim River.

RTM can locate Perak FM transmitter in Gunung Ulu Kali for South Perak area only, so that it provides better reception in Trolak, Slim River and Tanjung Malim than transmitted from Bukit Asa, even in Sungkai, Tapah, Bidor and Hilir Perak still can receive Perak FM from Gunung Ulu Kali. If Perak FM locates its transmitter in Gunung Ulu Kali, it is only for South Perak and nearby area like North Selangor (Hulu Selangor), not for Klang Valley and Pahang. Therefore, the reception of Perak FM from Gunung Ulu Kali will not be clear in Klang Valley, South Selangor and West Pahang, like Pahang FM 107.5MHz from Gunung Ulu Kali, only covers West Pahang.

Optionally, RTM Perak FM can migrate its Bukit Asa frequency from 89.6MHz to 89.5MHz, so this can avoid interference with 89.9MHz from Gunung Ulu Kali. In addition, with frequency migration to 89.5MHz, this can allow Perak FM to increase power to cover South Perak.
