Sungai Sumun is a small town, located in Bagan Datuk district, Perak. It is 30km away from Teluk Intan, 129km from Ipoh, 19km from Bagan Datuk and 160km from Kuala Lumpur.
About the radio coverage in this small town, Sungai Sumun is covered by Gunung Ulu Kali and Gunung Kledang FM transmission, however I received something unusual radio signal there on FM 96.0MHz.
FM 96.0MHz is usually Suria FM Ipoh frequency from Gunung Kledang in Teluk Intan, Bagan Datuk, Selekoh, Sungai Sumun and Hutan Melintang, but when I drove from Sabak Bernam to Bagan Datuk, I caught unknown Thailand radio station which played oldies on FM 96.0MHz in Sungai Sumun, Perak, Malaysia.
For the radio station, I could not fully identify what Thailand radio station on FM 96.0MHz was spotted in Sungai Sumun, Perak on the spot because I was driving. Hence, now I suspected two radio stations because they're Southern Thailand based.
1. MCOT Narathiwat
2. Unity Radio Krabi
Now analyze MCOT Narathiwat FM 96.0MHz reception possibility in Sungai Sumun, Perak, Malaysia.
MCOT Narathiwat height above sea level is 9m, meanwhile its antenna height is 120m. Transmitter power is 1kW, effective radiated power is 4kW. In terms of tropospheric transmission to Sungai Sumun, Perak, I think the possibility is low because there are many terrains between Narathiwat and Sungai Sumun. Distance is 301km.
Next, Unity Radio FM 96.0MHz Krabi. The reception possibility in Sungai Sumun, Perak, Malaysia was slightly higher than MCOT Narathiwat because there is no much terrain between Krabi and Sungai Sumun. Between both locations, actually it is the sea. Unity Radio TX site is located at Rodboon Road, Amphoe Mueang district, Krabi province, Thailand.
The distance between Unity Radio Krabi FM 96.0MHz TX site to Sungai Sumun, Perak, Malaysia is 511km.
Due to geographical condition, I suspected FM 96.0MHz that I received in Sungai Sumun, Perak, Malaysia was Unity Radio Krabi FM 96.0MHz. Actually this is tropospheric interference to Suria FM 96.0MHz Gunung Kledang local radio station coverage by Unity Radio Krabi FM 96.0MHz.
