RTM Asyik FM is now largely available in Negeri Sembilan via FM 95.6MHz from Gunung Ledang and 102.5MHz from Gunung Ulu Kali after the transmitter system upgrade

In June 2025, RTM Asyik FM upgraded its Gunung Ledang transmitter system 95.6MHz, this allows Asyik FM to reach more areas in Negeri Sembilan, together with 102.5MHz Gunung Ulu Kali transmitter.


Before the transmitter system upgrade, Asyik FM 95.6MHz was currently available in Gemas, Gemencheh, Rompin, Kuala Pilah, Batu Kikir, Bandar Seri Jempol and Bahau with weaker signal because it focused Segamat area in Johor only.


After Asyik FM 95.6MHz Gunung Ledang transmitter was upgraded in June 2025, it is clearer than before in Gemas, Gemencheh, Rompin, Kuala Pilah, Bahau, Bandar Seri Jempol and Batu Kikir, but it can reach even more areas in Negeri Sembilan such as Simpang Pertang, Simpang Durian, Johol, and Kuala Klawang.


For Seremban, Rembau, Nilai and Port Dickson, Asyik FM can be tuned moderately and weakly via 102.5MHz (Gunung Ulu Kali) or 91.1MHz (Kuala Lumpur Tower).


On 31st December 2025, I managed to record the radio signal videos of Asyik FM in new locations of Negeri Sembilan by following below:


1. Kuala Klawang


2. Simpang Pertang


3. Simpang Durian


Technically, Asyik FM 95.6MHz Gunung Ledang transmitter can reach Jelebu, Negeri Sembilan nowadays, but it is not clear as 102.5MHz. I believe that RTM Asyik FM 95.6MHz is using non-directional antenna in Gunung Ledang, but retaining its transmitter power at 0.25kW, so it can reach more areas in Negeri Sembilan, Pahang and part of Melaka, despite it mainly targets North Johor.


FM 95.6MHz is now available in Gemas, Jempol, Kuala Pilah and Jelebu, Negeri Sembilan.


Asyik FM can be tuned on 102.5MHz and 95.6MHz in Jelebu District, Negeri Sembilan nowadays. 


In Simpang Pertang, Simpang Durian and Peradong, 102.5MHz is clearer than 95.6MHz.


Asyik FM 95.6MHz is very clear in Jempol, Negeri Sembilan, comparing with 102.5MHz, but both 95.6MHz and 102.5MHz are clear in Bahau, Negeri Sembilan.


Asyik FM also can be tuned in Johol moderately on 95.6MHz nowadays.


From 2019 to 2025, I also recorded several videos of tuning Asyik FM on 102.5, 91.1 and 95.6 in Negeri Sembilan.


1. Seremban



2. Port Dickson



3. Kuala Pilah



4. Linggi



5. Bandar Seri Jempol



6. Mantin



7. Bahau



8. Rantau 



9. Rompin



10. Air Kuning Selatan (near Gemencheh and Batang Melaka)



11. Batu Kikir

Co-channel interference between Suria FM (TX_Gunung Ulu Kali) and RTM Johor FM (TX_Gunung Ledang) on the frequency 105.3MHz in Negeri Sembilan and Melaka

 



Generally Gunung Ledang radio transmitter mainly covers Melaka and North Johor, but RTM Johor FM 105.3MHz only covers North Johor areas like Tangkak, Muar, Segamat and North Batu Pahat, so this causes Johor FM 105.3MHz to have co-channel interference from Suria FM Gunung Ulu Kali transmitter in Melaka and Negeri Sembilan badly.


When Suria FM and Johor FM are interfering each other on FM 105.3MHz in Melaka and Negeri Sembilan, Suria FM can be tuned on 88.5MHz (Gunung Ledang) and 107.0MHz (Gunung Telapak Buruk), meanwhile Johor FM has no alternative frequency because Melaka and Negeri Sembilan are not its targeting coverage.


From 2016 to 2025, I managed to record the videos of co-channel interference radio signal of Suria FM and RTM Johor FM on the frequency 105.3MHz in Melaka and Negeri Sembilan.

MYTV has some coverage in Lubok Antu, Sarawak via Bukit Temudok DTT transmitter



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.


==MYTV Bukit Temudok DTT frequencies==

* MUX A: CH 47 (682MHz)

Analysis of FM 102.0MHz Gunung Telapak Buruk transmission (for Kool FM)

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.


Seremban dah Kool? Masih tak belum KOOL lagi.

RTM Nasional FM starts its trial transmission on shortwave frequency SW 15295kHz


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.
