Cameron Highlands is the only Pahang state where the radio listeners can receive Indonesia radio stations from North Sumatra, but tropospheric propagation.

Back to 1st May 2022, I managed to receive few Indonesia radio stations from North Sumatra (Medan, Deli Serdang) in Kinta Highlands, Perak, Malaysia where is not far from Cameron Highlands.

Now in 2024, my friend Mu'izz receives 3 Indonesia radio stations from North Sumatra in Tanah Rata, Cameron Highlands, Pahang.

Based on his videos, the Indonesia radio stations that he receives in Cameron Highlands are based in Medan and Langkat of North Sumatra Province, I was used to receive them in several Perak areas in 2022.

1. Radio Muslim Al-Fatih Medan FM 107.3MHz

Distance: 321km

2. Nastra FM 88.6MHz Langkat

Distance: 353km

3. Radio Maria Indonesia FM 104.2MHz Medan

Distance: 314km

Frankly, no interference with Minnal FM 104.3MHz Gunung Brinchang transmitter is detected when tune Radio Maria Indonesia in Tanah Rata on 104.2MHz.

I was used to tune these Indonesia radio stations in other locations two years ago.

1. Radio Muslim Al-Fatih Medan FM 107.3MHz in Teluk Intan, Bagan Datuk, Hutan Melintang, Sitiawan and Sungai Ayer Tawar.

2. Nastra FM 88.6MHz Langkat in Sungai Ayer Tawar.

3. Radio Maria Indonesia Medan FM 104.2MHz in Kinta Highlands.

Among these videos of 3 Indonesia radio stations tuned in Cameron Highlands, the strongest is Nastra FM 88.6MHz, meanwhile Radio Muslim Al-Fatih FM 107.3MHz Medan is the weakest radio station tuned there.

Radio Muslim Al-Fatih Medan FM 107.3MHz only operates 500W transmitter power.

I believe these Indonesia radio stations received in Cameron Highlands are tropospheric propagation because they are not constantly receivable.

Overall in Cameron Highlands, Nastra FM 88.6MHz from Langkat, Indonesia is the furthest radio station tuned there.
