Co-channel interference between RTM Selangor FM (Gunung Ulu Kali) and RTM Minnal FM (Bukit Bakar) on 100.9MHz in Kelantan and Pahang


Although RTM Selangor FM 100.9MHz from Gunung Ulu Kali mainly covers Selangor, but it can be tuned in West Pahang, Central Pahang, South Perak, part of Negeri Sembilan, and Melaka, meanwhile RTM Minnal FM is also using same frequency with Selangor FM in Bukit Bakar transmitter to cover Central Kelantan areas like Machang and Kuala Krai.


The most interesting point is Selangor FM 100.9MHz can be received in South Kelantan, but it has a strong co-channel interference with Minnal FM from Bukit Bakar.


It is very interesting when both radio stations are interfering each other on the frequency FM 100.9MHz in Kelantan and Pahang.


From 2021 to 2022, I had managed to record the co-channel interference radio signal videos of Selangor FM and Minnal FM in Pahang and Kelantan on the frequency FM 100.9MHz.

首要媒體中文電台“Eight無限”芙蓉頻率88.3斷線,“Eight無限”可以永久停播其芙蓉頻率88.3




首要媒體旗下的中文電台"Eight無限" (Eight FM)在2025年10月27日在馬六甲,柔佛和怡保停播,其頻率在2025年11月3日變成馬來語電台Kool FM。

目前“Eight無限”只有在5個區域廣播。

* 雪隆區 88.1
* 北馬 (檳城,太平,吉打) 87.8
* 芙蓉 88.3
* 亞庇 95.7
* 古晉 98.3

根據一位來自芙蓉的朋友,最近“Eight無限”的芙蓉頻率88.3沒有廣播,傳輸斷線了接近3天。到目前為止,“Eight無限”88.3在森美蘭芙蓉還沒恢復廣播。

在我的看法, 由於“Eight無限”已經升級為數碼優先的中文電台,所以FM電台頻率傳輸不再是它的主要平台。就算“Eight無限”沒有在芙蓉恢復廣播,其實它是已經不重要因為芙蓉頻率88.3覆蓋範圍很小,“Eight無限”也無法吸引很多聽眾收聽廣播。

“Eight無限”芙蓉頻率88.3是從芙蓉Jalan Rasah 的Bukit Gun 發射站傳輸訊號,覆蓋範圍只限芙蓉,其他電台則從Gunung Telapak Buruk 發射。

跟關丹的情況差不多一樣,我相信在芙蓉收聽“Eight無限”88.3的聽眾是非常少因為覆蓋範圍問題。

“Eight無限”88.3在芙蓉的森那旺 (Senawang),萬茂 (Mambau)和申達央(Sendayan)的線路其實很差,進入Sungai Gadut就沒有訊號。

以目前的狀態來看,不是所有的芙蓉地區可以通過88.3聽到“Eight無限”。

因為許多聽眾已經使用數碼平台收聽“Eight無限”, 我個人建議“Eight無限”永久關閉芙蓉頻率88.3的傳輸,並把頻率歸還給MCMC,這項建議意味著“Eight 無限”可以選擇在芙蓉停播。

88.3的收聽廣播範圍很小,所以“Eight 無限”在芙蓉繼續廣播已經沒有意義了。

若首要媒體在關閉"Eight無限"的廣播,這也可以為“Eight無限”節省不必要的傳輸費。

如果芙蓉頻率88.3讓給Kool FM也ok,但覆蓋範圍也一樣小,Kool FM無法吸引更多馬來聽眾。

除了數碼平台,“Eight無限”在雪隆區,檳城,亞庇和古晉廣播已經很足夠,芙蓉地區可以永久關閉。

Eight WuXian can switch off its Bukit Gun transmitted Seremban frequency FM 88.3MHz due to low listenership rating and small broadcast coverage.



Eight WuXian (formerly known as Eight FM) had already ceased broadcast in Ipoh, Melaka and Johor Bahru on 27th October 2025, then its frequencies are now used by Kool FM.


As today, Eight WuXian (Eight無限) only broadcasts in Klang Valley on FM 88.1MHz, Penang, Taiping and Kedah on FM 87.8MHz, Seremban on FM 88.3MHz, Kota Kinabalu on FM 95.7MHz and Kuching on FM 98.3MHz.


According to my friend who is staying in Seremban, Eight WuXian on FM 88.3MHz is currently off air in Seremban, Negeri Sembilan recently. I may suspect the transmitter system of FM 88.3MHz in Bukit Gun tower is damaged as it has been running for 16 years since One FM era.


As today, Eight WuXian FM 88.3MHz in Seremban, Negeri Sembilan is not back on air yet.


In my opinion, Media Prima Audio can permanently terminate Eight WuXian radio broadcast in Seremban, Negeri Sembilan and surrender the frequency FM 88.3MHz to MCMC.


This is because the coverage of Eight WuXian FM 88.3MHz is very small as it is transmitted from Bukit Gun, meanwhile other radio stations are transmitted from Gunung Telapak Buruk. In addition, the transmission of Eight WuXian FM 88.3MHz doesn't reach many listeners.


Eight WuXian FM 88.3MHz is already weak in Senawang, Sendayan and Mambau where are within Seremban City.


Besides that, same like Kuantan, I don't think Eight WuXian has potential listeners in Seremban.


Media Prima Audio can make another option to switch Eight WuXian to Kool FM on 88.3MHz in Seremban, Negeri Sembilan if MCMC doesn't allow the radio transmission of FM 102.0MHz in Gunung Telapak Buruk.


Media Prima Audio can launch Kool FM in Seremban by taking over the frequency from Eight WuXian, at least Kool FM can gain potential listeners in Seremban, despite 88.3MHz doesn't cover entire Negeri Sembilan state.


If Media Prima Audio permanently terminates the transmission of Eight WuXian FM 88.3MHz in Seremban, Negeri Sembilan, Eight WuXian will remain 4 FM radio frequencies in Klang Valley, Penang, Kota Kinabalu and Kuching. This can help Media Prima Audio to save transmission fees for Eight WuXian.


Seremban is not an important market of Eight WuXian, somewhat Eight WuXian is digital first Chinese radio station which mainly focuses on digital platform over conventional FM radio platform.


Alongside digital platform, it is already sufficient of Eight WuXian to focus in Klang Valley, Penang, Kota Kinabalu and Kuching on FM radio frequency platform because many listeners have already tuned to this radio station digitally nowadays.

How to access RTM Wai FM via satellite feed in rural areas?




Dear all Wai FM radio listeners, as Wai FM had ceased operation on Astro CH871, so the listeners can only access via MYTV, RTM Klik or FM radio frequencies.


For rural areas like Ulu Baram, Bario etc, there are no coverage from FM radio and DVB-T2 transmitters, even internet connection is not stable at all, some of locations may have no internet coverage, leaving only 2G signal which only allows phone calls and SMS.


To access Wai FM in rural areas without Astro and MYTV terrestrial platform, I strongly suggest to tune via satellite signal with independent satellite receivers and C band parabolic dish by receiving C band signal.


MYTV DTH transmission is not recommended due to Ku band satellite, unless you don't mind of rainfade.


Here are the satellite frequencies of tuning Wai FM with local channel number.


1. C band 

* 3.871GHz ABS-2 75DEG (CH710)

* 3.880GHz MEASAT-3d 91.5DEG (CH1012)


2. Ku Band

* 11.550GHz ASIASAT-9 (CH710)


RTM Wai FM is no longer available on Astro CH871 since 9th January 2026




Effective 9th January 2026, all RTM radio stations are no longer available on Astro.


RTM Wai FM ceased broadcast on Astro CH871.


This is a bad news to Sarawak's rural community, but RTM Wai FM can be tuned alternatively on MYTV CH710 and online based RTM Klik.


It is because there is a decline of radio listenership on Astro DVR platform, many people tune a radio on a mobile phone via online streaming platform (RTM Klik) over TV set-top-box platform.






Wai FM on Astro CH871 carried Iban, Lun Bawang, Kayan and Kenyah programs. Since it is no longer available on Astro, the listeners have to tune alternatively by following platform below:


1. Wai FM Iban

* RTM Klik - Wai FM Iban

* MYTV CH710 (12am to 12pm, 6pm to 12am)

* FM 101.3MHz in Kuching and part of Betong/Sri Aman Division, FM 106.9MHz in Serian (24 hours broadcast)

* Sibu FM, Sri Aman FM, Bintulu FM (12am to 9am, 12pm to 12am)

* Miri FM (12am to 9am, 12pm to 3pm, 6pm to 12am)

* Limbang FM (12am to 9am, 6pm to 12am)


2. Radio Tau (Limbang FM's Lun Bawang language program)

* RTM Klik - Limbang FM

* MYTV CH710 (12pm to 3pm)


3. Radio Kayan (Miri FM)

* RTM Klik - Wai FM Bidayuh/Kayan (12pm to 6pm)

* MYTV CH710 (3pm to 5pm)

* FM 106.1MHz in Kuching and part of Sri Aman/Betong Division, FM 106.9MHz in Serian (12pm to 6pm)


4. Talidio Kenyah (Miri FM)

* RTM Klik - Miri FM (5pm to 6pm)

* MYTV CH710 (5pm to 6pm)

* Facebook LIVE & YouTube (3pm to 6pm)


Regarding MYTV, it has no terrestrial coverage in rural areas of Sarawak, so the people need to install MYTV DTH Ku band satellite dish (Asiasat-9 at 122DEG on 11.55GHz) or C-band parabolic dish (ABS-2 at 75DEG on 3.871GHz or MEASAT-3D at 91.5DEG on 3.880GHz). To avoid rainfade, I strongly recommend to use C band parabolic dish to access Wai FM in rural areas where there have no internet connectivity or MYTV DVB-T2 coverage.


Internet can be accessed in Malaysia rural areas via Starlink, so the listeners can access Wai FM via RTM Klik and various online platform easily.


Wai FM Iban is mostly available on Sri Aman FM, Sibu FM and Bintulu FM for 21 hours, but Wai 9-12 is not available from 9am to 12pm program on local radio stations outside Kuching and Serian because they carry 3 hours Malay language program, then Wai FM Iban is not available from 6pm to 7pm on local radio stations on Ramadan month annually. As Wai FM is no longer available on Astro CH871, then shortwave frequency SW 11665kHz is temporarily unavailable due to transmitter was damaged, so the listeners outside Kuching and Serian can only tune to Wai FM Iban on affected hours via MYTV CH710 or RTM Klik, but Wai FM Iban can be tuned via distant frequency 101.3MHz from Gunung Serapi transmitter in some areas of Sri Aman Division and Betong Division, Sarawak such as Simanggang, Engkilili, Lingga, Pusa, Saratok and Roban, meanwhile it is super weak in Debak, Betong and Spaoh.


Here is the radio reception videos of Wai FM Iban in various locations of Sri Aman and Betong Division, Sarawak where Cock DXer and me recorded in 2025.

 

1. Simanggang, Sarawak (147km)

 

2. Betong, Sarawak (151km)


3. Engkilili, Sarawak (172km)


4. Spaoh, Sarawak (145km)


5. Debak, Sarawak (138km)


6. Saratok, Sarawak (129km)


7. Roban, Sarawak (129km)


8. Pusa, Sarawak (120km)



9. Kabong, Sarawak (106km)

(AUSTRALIA FM DX) ABC Northern Tasmania tuned in Melbourne, Victoria State


ABC Northern Tasmania is a local radio station based in Launceston, its main target coverage is the northern part of Tasmania state, however a Melbourne based radio DXer, named VKS2WL managed to tune ABC Northern Tasmania in Greater Melbourne, VIC on various FM frequencies, however these radio reception were tropospheric propagation.


1. FM 91.7MHz - Launceston (TX: Mount Barrow)


Receiving distance: Approximately 450-470km


2. FM 91.3MHz - Lileah (TX: Willis Hill)


Distance: Approximately 367km


3. FM 106.3MHz - Rosebery (TX: Mount Read)


Distance: Approximately 470km


4. FM 88.5MHz - King Island (TX: Gentle Annie)


Distance: Approximately 258km. Weak signal with adjacent channel interference from 3SCB Southern FM 88.3MHz.


Most of the videos were recorded in Westmeadows, an suburb town of Melbourne, VIC. Among all 4 frequencies, FM 91.3MHz from Lileah was the clearest, following by FM 91.7MHz from Launceston, but FM 106.3MHz from Rosebery was the weakest frequency in Melbourne.


In Melbourne City, ABC Radio is locally available by following stations below:

* Radio National AM 621kHz

* ABC Melbourne AM 774kHz

* News Radio AM 1026kHz

* Classic FM 105.9MHz

* Triple J FM 107.5MHz


During nighttime transmission after sunset, ABC Hobart AM 936kHz from Tasmania can be received in Melbourne.

Malaysia TV and radio channels can be accessed in Australia via C-band satellite from MEASAT-3d 91.5°E and ABS-2 75°E

In Australia, alongside online streaming platform, the TV and radio stations can be accessed through C-band satellite from MEASAT-3d and ABS-2.


People's in Australia can access these channels by installing C-band receiving satellite dish and DVB-S2X receiver with the following C-band frequencies and channels below from Lyngsat:




Malaysia's MYTV C-band TV and radio channels via ABS-2 satellite are using DVB-S2X standard which is an extended version of DVB-S2, meanwhile RTM radio stations via Measat-3D are using DVB-S2 standard. 

Based on the C-band coverage, Measat-3D and ABS-2 satellite signal still can reach Australia, except Tasmania where is an island state. Hence, the Malay community in Katanning of Western Australia state and Cocos (Keeling) Islands can receive Malaysia TV and radio stations via C band satellite. 

Note: Several channels may not be accessible due to encryption.





List of RTM radio stations which are available via MEASAT-3d at 91.5°E C-band transmission.



Sources: Lyngsat


The main function of using C-band satellite transmission by RTM Malaysia via Measat-3d is to send the signal feeds from broadcasting houses (studio) to the transmitter sites, notably remote area.

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
