MCOT Yala 102.5MHz interference with THR Raaga 102.4MHz?

MCOT Yala currently broadcasts on FM 102.5MHz, transmitter located in Bannang Sata district (Narathiwat-Yala border). It covers Yala, Narathiwat and Pattani, also can be received in Kelantan with weaker signal.

Betong is one of district in Yala, located near Kedah and Perak, it is the southernmost area in Thailand.

MCOT Yala can be received clearly in most of Yala provinces, but it interferes with THR Raaga 102.4MHz from Gunung Jerai (which is Malaysia Tamil radio station) in Betong, caused MCOT Yala cannot be received in Betong, same as Radio Thailand Yala 95.0MHz.

Here is the radio frequency analysis.

1. MCOT Yala 102.5MHz vs. MY FM Bukit Panau 102.3MHz
Spacing: 200kHz, OK (Comply with JTC agreement)

2. MCOT Yala 102.5MHz vs. Nasional FM Bukit Dedap 102.7MHz
Spacing: 200kHz, OK (Comply with JTC agreement)

3. MCOT Yala 102.5MHz vs. THR Raaga Gunung Jerai 102.4MHz
Spacing: 100kHz. Although Malaysia and Thailand agreed the separation, but interference occurs in Betong Thailand.

Because Yala radio frequency is very sensitive to many sites due to its height, which involves Gunung Jerai, Gunung Raya, Bukit Palong, Bukit Dedap, Narathiwat, Gerik, Bukit Panau, Pattani, Sungai Kolok, Bukit Bintang, Songkhla, Telipot and Peringat, so it is difficult to change parameters.

There is a solution which can solve the interference of MCOT Yala 102.5MHz with THR Raaga 102.4MHz in Betong.

In order to improve the coverage of MCOT Yala in Southern Yala (Betong district), MCOT Yala should add 1 more transmitter in Betong district.

In my opinion, there is a frequency which is suitable for MCOT Yala to be set up additional transmitter in Betong Thailand, FM 104.7MHz.
