MYTV DTT (Digital Terrestrial Television) transmitter in Bukit Temudok mainly covers Sri Aman (Simanggang), Lingga, Engkilili, Betong, Spaoh, Lachau and Pantu.
Lubok Antu is likely a blindspot coverage of MYTV DTT transmitter from Bukit Temudok, but technically it's not at all by looking at the official coverage map of MYTV DTT transmitters.
According to the coverage map, there is still having the coverage of MYTV DTT transmitter from Bukit Temudok in Lubok Antu, Sarawak, except Batang Ai area.
The signal of MYTV DTT transmitter from Bukit Temudok is likely unstable in certain locations of Lubok Antu, Sarawak, the viewers need to use at least 14e outdoor antenna to receive a stable signal of DTT service
No coverage in Batang Ai.
MYTV Bukit Temudok DTT transmitter can reach until Indonesia border (Badau, West Kalimantan Province).
To access MYTV digital terrestrial television signal in Lubok Antu, Sarawak, outdoor antenna is the minimum requirement by pointing the direction to northwest towards Bukit Temudok transmitter.
Distance from Bukit Temudok to Lubok Antu is 45km.

Lubok Antu is located in the south-easternmost of Sri Aman Division, Sarawak, it is not far from Indonesia border.
Note: Despite Lubok Antu is not far from Indonesia border (West Kalimantan), Radio Republik Indonesia RRI Sintang stations (PRO-1 on FM 102.5MHz, PRO-2 on FM 90.7MHz and PRO-3 on FM 96.6MHz) are not likely receivable in Lubok Antu, Sarawak, Malaysia due to terrain. In addition, it is still far between Lubok Antu and Sintang. No guarantee of RRI Sintang PRO-1 FM 95.9MHz Badau repeater can be tuned in Lubok Antu, Sarawak.
Only 8 radio stations are available in Belaga town, Sarawak, the coverage is limited in Belaga town and surrounding areas. None of distant (DX) radio stations can be detected in Belaga.
Note: Belaga transmitted radio stations have no signal in Sungai Asap.
On 3rd November 2025, Kool FM had reached Ipoh (87.6), Melaka (88.1) and Johor Bahru (105.3) by taking over the frequencies from Eight FM.
As today, Kool FM has not launched Seremban frequency yet, but I attempted to propose Kool FM to use 102.0MHz in Gunung Telapak Buruk to cover Negeri Sembilan recently.
FM 102.0MHz is currently an empty frequency in Negeri Sembilan, so I think there is a potential of Kool FM can use this frequency in Seremban generally, transmitted from Gunung Telapak Buruk, but technically it has no guarantee whether MCMC approves this frequency or not for Gunung Telapak Buruk radio transmission by Kool FM.
101.8MHz: MY FM Gunung Ulu Kali
102.0MHz: Kool FM Gunung Telapak Buruk
(200kHz, OK)
102.0MHz: Kool FM Gunung Telapak Buruk
102.3MHz: Melaka FM Gunung Ledang
(300kHz, OK)
102.0MHz: Kool FM Gunung Telapak Buruk
102.2MHz: Pahang FM Bukit Fraser
(200kHz, OK)
101.9MHz: Johor FM Gunung Pulai
102.0MHz: Kool FM Gunung Telapak Buruk
(100kHz, NOT OK as Johor FM has already separated with MY FM 101.8MHz at 100kHz)
By looking at RTM radio stations from Gunung Pulai, none of radio stations separate at 100kHz with Gunung Telapak Buruk radio stations, despite there are examples of 100kHz frequency separation between Gunung Pulai and Gunung Telapak Buruk radio stations by following below:
87.8MHz: Sinar FM Gunung Pulai
87.9MHz: Radio Klasik Gunung Telapak Buruk
101.4MHz: Suria FM Gunung Pulai
101.5MHz: Raaga FM Gunung Telapak Buruk
103.6MHz: Era FM Gunung Telapak Buruk
103.7MHz: Raaga FM Gunung Pulai
104.5MHz: Era FM Gunung Pulai
104.6MHz: Lite FM Gunung Telapak Buruk
For RTM radio stations, Traxx FM 102.9MHz Gunung Pulai has 200kHz frequency separation with IKIM FM 102.7MHz Gunung Telapak Buruk transmitter, most of its radio stations have 0kHz or 100kHz with Gunung Ulu Kali transmitted radio stations by following below:
101.8MHz: MY FM Gunung Ulu Kali
101.9MHz: Johor FM Gunung Pulai
102.9MHz: Traxx FM Gunung Pulai
103.0MHz: Melody FM Gunung Ulu Kali
104.9MHz: Zayan FM Gunung Ulu Kali
104.9MHz: Ai FM Gunung Pulai
105.7MHz: Lite FM Gunung Ulu Kali
105.7MHz: Nasional FM Gunung Pulai
106.7MHz: Ai FM Gunung Ulu Kali
106.7MHz: Radio Klasik Gunung Pulai
When RTM Johor FM 101.9MHz already has 100kHz frequency separation with MY FM 101.8MHz, both radio stations are interfering each other in North Johor areas like Segamat, Batu Anam, Sungai Mati, and part of Muar. RTM Johor FM 101.9MHz will have more interference in North Johor if the frequency FM 102.0MHz is used in Gunung Telapak Buruk.
Back to January 2023, I managed to record the videos of tuning RTM Johor FM 101.9MHz in Segamat and Batu Anam, it was already having interference with MY FM 101.8MHz. If I propose FM 102.0MHz Gunung Telapak Buruk radio transmission for Kool FM in Negeri Sembilan, it will be even worse.
101.8MHz: MY FM Gunung Ulu Kali
101.9MHz: Johor FM Gunung Pulai
102.0MHz: Kool FM Gunung Telapak Buruk
When it comes to this situation, Johor FM 101.9MHz is badly "sandwiched" by MY FM 101.8MHz and Kool FM 102.0MHz. Although Johor FM can be tuned loudly and clearly on 105.3MHz Gunung Ledang transmitter in North Johor, but Johor FM 101.9MHz also backs up some blindspot areas of 105.3MHz such as Seri Medan, Parit Sulong and Yong Peng.
Some areas between Yong Peng and Chaah rely on FM 101.9MHz because Johor FM cannot be received clearly on FM 105.3MHz due to terrains. If FM 102.0MHz is used in Gunung Telapak Buruk, Johor FM 101.9MHz will suffer interference in these areas while 105.3MHz has poor signal, so Johor FM has no alternative frequency in affected areas.
In addition, Gunung Telapak Buruk radio transmission can overspill signal to part of Kluang where is the coverage of Johor FM 101.9MHz from Gunung Pulai transmitter. In Kluang District (except Paloh and Kahang) and part of Batu Pahat District (Ayer Hitam, Sri Gading, Seri Medan, Rengit, Senggarang, and part of Yong Peng), Johor FM is mostly tuned on 101.9MHz from Gunung Pulai which is clearer than 105.3MHz from Gunung Ledang.
In conclusion, when Johor FM 101.9MHz and MY FM 101.8MHz are already having "interference war" in North Johor and Melaka, I may not recommend FM 102.0MHz to be used in Gunung Telapak Buruk for Negeri Sembilan, even if I present the RF proposal to MCMC, I don't think there is guarantee whether MCMC will approve or reject this frequency transmission, regardless low or high transmitter power.
Today my friend, Sarawut DXer from Langkawi, Kedah tunes RTM Nasional FM on shortwave frequency SW 15295kHz.
According to him, Nasional FM performs test transmission on SW 15295kHz, transmitted from RTM Kajang, but the signal is negative in Balakong, Selangor when I reached home at 6.15pm (UTC+8) because Nasional FM shortwave test transmission ends at 5.15pm.
Nasional FM on SW 15295kHz from RTM Kajang is loud and clear in Langkawi, Kedah.
Currently Radio Televisyen Malaysia (RTM) Nasional FM has not released any official announcement regarding its shortwave radio transmission SW 15295kHz, so I classify the radio broadcast on SW 15295kHz as the test transmission.

Di Kuala Rompin, Pahang, RTM Johor FM masih boleh didengari pada frekuensi 92.1MHz dari pemancar Bukit Tinggi yang meliputi Mersing, Endau, Jemaluang dan Pantai Timur Johor.
Pada tahun 2022 dan 2023, saya telah merakam video isyarat radio Johor FM 92.1MHz di Kuala Rompin, Pahang. Pada masa itu, saya tidak merakam isyarat frekuensi FM 105.3MHz di Kuala Rompin kerana saya memberi lebih perhatian kepada FM 92.1MHz. Johor FM 105.3MHz pun bercampur-baur dengan Suria FM sebelum pemancar Gunung Ledang dinaiktaraf pada Jun 2025.
Walaupun siaran Johor FM 92.1MHz masih boleh didengari dengan sederhana di Kuala Rompin, tetapi ia diganggu hebat oleh Pahang FM 91.9MHz akibat jarak frekuensi antara Pahang FM 91.9MHz dan Johor FM 92.1MHz ialah 200kHz.
Pahang FM 91.9MHz dipancar dari TM Kuala Rompin, meliputi Kuala Rompin dan Nenasi.
Apabila Johor FM 92.1MHz diganggu oleh Pahang FM 91.9MHz di Kuala Rompin, pendengar Johor FM di kawasan tersebut boleh mendengar siaran radio ini secara alternatif pada frekuensi FM 105.3MHz yang dipancar dari Gunung Ledang pada masa sekarang kerana sistem pemancar Johor FM 105.3MHz di Gunung Ledang telah dinaiktaraf pada Jun 2025, isyarat adalah sederhana di Kuala Rompin.
Terima kasih kepada Mu'izz untuk merakam video isyarat radio RTM Johor FM 105.3MHz di Kuala Rompin, jarak dari Gunung Ledang ialah 110km.
Pada 3hb November 2025, Kool FM telah memperluaskan siarannya ke Melaka, Johor dan Ipoh dengan mengambil alih frekuensi Eight FM di negeri-negeri tersebut.
Kool FM kini boleh didengari di Ipoh pada frekuensi 87.6MHz, Melaka pada 88.1MHz dan Johor Bahru pada 105.3MHz.
Kini slogan Kool FM ialah Malaysia Dah Kool, tetapi PANTAI TIMUR BELUM KOOL lagi.
Buat masa sekarang, Kool FM belum lagi bersiaran di Pantai Timur seperti Kuantan, Kuala Terengganu dan Kota Bharu.
Terdapat orang bertanya adakah Kool FM akan menambah frekuensi di Kuantan, Kuala Terengganu dan Kota Bharu selepas Kool FM mendarat di Ipoh, Melaka dan Johor Bahru.
Pada pandangan saya, dengan keadaan lesen penyiaran radio, penambahan frekuensi Kool FM di Pantai Timur adalah mustahil kerana Pantai Timur sudah mempunyai radio Molek FM.
Untuk makluman, Kool FM dan Molek FM berkongsi dengan satu lesen penyiaran radio di bawah naungan KOOL FM RADIO SDN BHD. Di bawah peraturan SKMM (MCMC), oleh kerana Molek FM sudah bersiaran di Kuantan, Kota Bharu dan Kuala Terengganu, Kool FM tidak dibenarkan untuk bersiaran di kawasan tersebut dengan frekuensi baru, kecuali dibenarkan oleh SKMM.
Sama dengan THR Gegar dan Raaga, radio THR Gegar sudah bersiaran di Kuantan, Kuala Terengganu dan Kota Bharu, oleh itu Raaga tidak dibenarkan untuk menambah frekuensi di Pantai Timur kerana Gegar dan Raaga berkongsi dengan satu lesen penyiaran di bawah naungan RADIO LEBUHRAYA SDN BHD.
Maka, Kool FM tidak akan bersiaran di Kuantan, Kuala Terengganu dan Kota Bharu dengan frekuensi baru kerana Molek FM sudah bersiaran di kawasan situ.
Walaupun Kool FM pernah bersiaran di Kota Bharu dan Kuala Terengganu sebelum frekuensi diambil alih oleh Molek FM, tetapi Kool FM tidak akan kembali bersiaran di kawasan tersebut kerana SKMM hanya membenarkan satu stesen bersiaran di Kota Bharu dan Kuala Terengganu.
From Sibu to Kapit, RTM Sibu FM is covered by 3-4 transmitters all the way, FM 87.6MHz Bukit Lima, FM 102.1MHz Bukit Singgalang, FM 99.8MHz Bukit Song and FM 94.3MHz Bukit Kapit, however there is a blindspot coverage of these transmitters in Kanowit, Sarawak.
RTM Sibu FM has no local gap filler transmitter in Bukit Memaloh for Kanowit like Sarawak FM 107.1MHz and Nasional FM 104.5MHz, so I need to tune Sibu FM on 102.1MHz from Bukit Singgalang transmitter.
In Kanowit, RTM Sibu FM 87.6MHz and 102.1MHz are not clear, but in terms of signal strength, 102.1MHz has better signal and dominates more coverage than 87.6MHz in Kanowit town. If I tune from Kanowit to Song, 87.6MHz and 102.1MHz are moderate and weak together vice-versa.
While Bukit Song transmitted radio stations like RTM Radio Klasik FM 91.1MHz, Traxx FM 96.7MHz, Red FM 99.0MHz, and RTM Ai FM 97.5MHz can be tuned clearly in between Kanowit and Song (Nanga Ngerah), but Sibu FM 99.8MHz cannot be tuned clearly due to adjacent channel interference with Cats FM 99.9MHz Bukit Singgalang transmitter as both radio stations' frequency separation is at 100kHz.
In my opinion, RTM Sibu FM should launch a gap filler transmitter in Bukit Memaloh to cover Kanowit, Sarawak where is the blindspot coverage of 102.1MHz (Bukit Singgalang) and 87.6MHz (Bukit Lima). Hence, the listeners can tune Sibu FM in Kanowit loudly and clearly from Bukit Memaloh transmitter tower. When Sibu FM 102.1MHz and 87.6MHz are super weak in between Kanowit and Song, while 99.8MHz is interfered with Cats FM 99.9MHz, the listeners can tune to this radio station on Kanowit frequency clearly.
If RTM Sibu FM adds Kanowit transmitter, so RTM has 3 radio stations in this town. In addition, Sibu FM instantly fills the coverage gap in between Sibu and Song.
Regarding the frequency, there are plenty of empty frequencies slots in Kanowit. Based on radio frequencies bandscan, I have listed down the frequency availability for Sibu FM in Kanowit.
* 98.1MHz
* 100.3MHz
* 103.7MHz
* 105.5MHz
* 106.3MHz
==RF analysis==
1. FM 98.1MHz

104.1MHz: RTM Red FM Bukit Lima
<400kHz, OK>
103.7MHz: RTM Sibu FM Kanowit
104.5MHz: RTM Nasional FM Kanowit
<800kHz, OK>
4. FM 105.5MHz
105.1MHz: Hitz FM Bukit Lima
105.5MHz: RTM Sibu FM Kanowit
<400kHz, OK>
105.3MHz: RTM Ai FM Bukit Temudok
105.5MHz: RTM Sibu FM Kanowit

104.5MHz: RTM Nasional FM Kanowit
105.5MHz: RTM Sibu FM Kanowit
<1MHz, OK>
5. FM 106.3MHz
105.9MHz: MY FM Bukit Lima
106.3MHz: RTM Sibu FM Kanowit
<400kHz, OK>
106.3MHz: RTM Red FM Bukit Temudok
106.3MHz: RTM Sibu FM Kanowit
<0kHz, OK>
106.3MHz: RTM Sibu FM Kanowit
107.1MHz: RTM Sarawak FM Kanowit
<800kHz, OK>
Among these 5 frequencies, based on the RF analysis, I recommend 98.1MHz or 105.5MHz as the Kanowit frequency of RTM Sibu FM because they meet the minimum frequency separation with the existing stations.
As today, Sibu FM is tuned in Kanowit, Sarawak weakly on 102.1MHz from Bukit Singgalang transmitter.
