RTM Johor FM 92.1MHz (Bukit Tinggi) & 101.9MHz (Gunung Pulai) tuned in Tamparuli, Sabah by Kisah Alkisah at the first time, but Sporadic E propagation.

  

In February and June 2026, the Sabah radio DXer, Kisah Alkisah had successfully received the radio signal of RTM Johor FM on 92.1MHz and 101.9MHz in Tamparuli, Sabah, both frequencies are Sporadic E signal.

 

Tamparuli is a small town located in Tuaran District, West Coast Division, Sabah, it is 39km from Kota Kinabalu City.

 

RTM Johor FM 92.1MHz is transmitted from Bukit Tinggi for Mersing, Kahang, Jemaluang and Endau, meanwhile 101.9MHz is transmitted from Gunung Pulai for Central-South Johor (Johor Bahru, Pontian, Kota Tinggi, Kulaijaya, Kluang and Southern Batu Pahat), Singapore and Riau Islands Indonesia (eg: Batam, Bintan, Karimun).

 

Sporadic E radio propagation is only happened for a short while, the signal goes disappeared after Sporadic E propagation season ends.

 

Here are two videos of tuning RTM Johor FM in Tamparuli, Sabah by Kisah Alkisah via Sporadic E propagation.

 

1. FM 92.1MHz Bukit Tinggi 1kW (1461km)

 

 

2. FM 101.9MHz Gunung Pulai 2kW (1498km)

 

Both are moderately weak in Tamparuli, Sabah, but their signal propagation don't hold for long duration. 

 

For FM 92.1MHz, despite it is just 200kHz from RTM Ai FM 91.9MHz from Lawa Mandau transmitter which covers Tamparuli too, but no adjacent channel interference noise from RTM Ai FM 91.9MHz is heard when tuned RTM Johor FM 92.1MHz in Tamparuli.

 

As none of local radio station is using the frequency near 101.9MHz such as 101.8MHz and 102.0MHz, RTM Johor FM 101.9MHz is tuned in Tamparuli without having any interference noise, but during Sporadic E propagation season, it has adjacent channel interference from Indonesia radio station on FM 102.0MHz. 

 

During normal radio propagation, FM 101.9MHz is empty frequency in Tamparuli, Sabah, meanwhile FM 92.1MHz is weak radio signal from RTM Nasional FM Bukit Trig transmitter occasionally, otherwise simply adjacent channel noise of RTM Ai FM 91.9MHz Lawa Mandau transmitter.

 

RTM Nasional FM 92.1MHz covers Sandakan mainly, but it can be detected weakly in Tamparuli, Kundasang and Tuaran.

 

Congratulations to Kisah Alkisah for successfully receiving RTM Johor FM 92.1MHz and 101.9MHz in Tamparuli, Sabah via Sporadic E propagation.
