RTM (Radio Televisyen Malaysia) gap filler radio transmitters in Bukit Kamiri are dead (off air) recently, so the listeners in Semporna, Sabah can continue listening to the broadcast moderately via Gunung Silam transmitter.

Two days before Hari Raya Aidilfitri, a Sabah radio DXer, Kisah Alkisah visited Lahad Datu and Semporna, Sabah, then he published a radio off air video of RTM Bukit Kamiri transmitter in Semporna, Sabah on YouTube.

Radio Televisyen Malaysia (RTM) launched gap filler transmitters for Nasional FM (89.1MHz), Sabah FM (91.1MHz) and Tawau FM (88.3MHz) in Bukit Kamiri to cover Semporna, Sabah since 2017 because Gunung Silam transmitter signal is not so clear there, meanwhile non-priority radio stations such as Traxx FM, Ai FM, Sabah VFM and Radio Klasik have no Bukit Kamari transmitters for Semporna.

Bukit Kamiri transmitter targets indoor radio listening in Semporna, Sabah where the listeners can tune to Nasional FM, Sabah FM and Tawau FM loudly and clearly there.

According to Kisah Alkisah, RTM Bukit Kamari transmitters were dead since February 2026.

I visited Semporna, Sabah today morning. I also checked RTM Bukit Kamari transmitted radio stations on 88.3MHz (Tawau FM), 89.1MHz (Nasional FM) and 91.1MHz (Sabah FM) in Semporna, they had no signal at all too.

Dear Semporna radio listeners who tune Nasional FM, Tawau FM and Sabah FM, Bukit Kamari transmitters are off air now, please tune to Gunung Silam transmitted frequencies by following stations below:

1. Nasional FM 88.7MHz

2. Sabah FM 89.7MHz

3. Tawau FM 93.9MHz

Traxx FM, Ai FM, Radio Klasik and Sabah VFM are not affected because they are already tuned via Gunung Silam transmitters in Semporna, Sabah by following below:

* Traxx FM 90.5MHz

* Ai FM 91.7MHz

* Sabah VFM 92.6MHz

* Radio Klasik FM 87.9MHz

I also performed signal check of RTM Sabah VFM and Sabah FM in Semporna, Sabah by comparing the radio signal between Gunung Silam and Gunung Andrassy transmitters.

In Semporna, Gunung Silam signal is better than Gunung Andrassy overall.

Even semi-commercial Islamic radio station IKIM FM is also tuned on 107.3MHz from Gunung Andrassy in Semporna, Sabah.

In my opinion, if RTM doesn't wish to continue the broadcast transmission of Bukit Kamari transmitter, RTM should increase the transmitter power of Gunung Silam transmitter from 1kW to 2kW, so Semporna can receive better signal.
