Previously in May 2025, I had managed to record the radio reception videos of RTM Wai FM Iban and Wai FM Bidayuh/Kayan in each town from Simanggang to Roban by tuning the frequencies from Gunung Serapi (101.3MHz Iban and 106.1MHz Bidayuh).
Both RTM Wai FM Iban and Wai FM Bidayuh/Kayan have Serian frequencies, transmitted from Gunung Ampungan.
Iban: 106.9MHz
Bidayuh/Kayan: 101.7MHz
On Pan Borneo Highway from Serian to Simanggang town, Wai FM Iban 106.9MHz and Bidayuh/Kayan 101.7MHz can be tuned until Lachau, then the signal becomes weak after Bukit Bangunan.
RTM Wai FM Iban 106.9MHz and Wai FM Bidayuh/Kayan 101.7MHz from Gunung Ampungan are still clear in Lachau, meanwhile 101.3MHz (Iban) and 106.1MHz (Bidayuh/Kayan) from Gunung Serapi are very weak in Lachau, Sarawak.
For Wai FM Iban listeners, although they can tune to Wai FM Iban in Lachau loudly and clearly via Sri Aman FM 89.5MHz from Bukit Temudok transmitter, but they can switch alternatively to 106.9MHz from Gunung Ampungan in Lachau, Sarawak when Sri Aman FM 89.5MHz airs 3 hours Malay local program from 9am to 12pm daily and 1 hour Malay Ramadan program from 6pm to 7pm during Muslims' Ramadan month annually.
Lachau is my latest location in Sri Aman Division, Sarawak to tune Wai FM Iban and Bidayuh, but via Serian frequencies (106.9MHz Iban & 101.7MHz Bidayuh/Kayan).
From Kuching to Sri Aman, 3 of Media Prima Audio (MPA) radio stations such as Hot FM 94.3MHz, Kool FM 104.3MHz and Eight WuXian FM 98.3MHz can be tuned clearly up to Lachau, Sarawak where Lachau is located in west part of Sri Aman Disivion (not far from Balai Ringin in Serian).
Here are the radio reception videos of MPA radio stations in Lachau, Sarawak where I record today while on the way to Kuching and Bau before flying back to Kuala Lumpur.
1. Hot FM 94.3MHz (124km from Gunung Serapi)
2. Kool FM 104.3MHz (106km from Bukit Djin)
3. Eight WuXian FM 98.3MHz (106km from Bukit Djin)
Compare to Simanggang where I recorded last year, these MPA radio stations in Lachau are clearer.
Hot FM 94.3MHz is still clear in Lachau without interference noise from RTM Sarawak FM 94.4MHz Off Spaoh transmitter like what I tuned in Simanggang town last year.
Kool FM 104.3MHz in Lachau has clearer signal than Simanggang and Engkilili.
Eight WuXian FM 98.3MHz is the most powerful Kuching's Chinese radio station in Sri Aman (Lachau, Simanggang and Lingga) by comparing to Tea FM 102.7MHz, meanwhile Astro Audio Chinese radio stations such as MY FM 96.9MHz and Melody FM 103.7MHz have no signal in Sri Aman, Sarawak, despite these radio stations are transmitted from Bukit Djin.
After Lachau, the radio signal of Hot FM 94.3MHz, Eight WuXian FM 98.3MHz and Kool FM 104.3MHz become very weak while heading to Simanggang or Engkilili.
Lachau is the best location to tune these MPA radio stations in Sri Aman Division of Sarawak, following by Lingga, Simanggang and Engkilili.

After having radio signal monitoring in Lubok Antu, I proceed to Lingga, Sarawak in the evening to continue my radio DXpedition. Before driving to Lingga, I take a break at Seri Simanggang Hotel in Sri Aman.
Lingga is a small town in Sri Aman Division, it is 49km from Simanggang town.
Generally Lingga is under the coverage of Bukit Temudok radio transmitter, but several Kuching radio stations from Gunung Serapi and Bukit Djin can be received there.
Same as Simanggang where I did in May 2025, I record several Kuching radio stations in Lingga by following below:
1. RTM Wai FM Iban (101.3MHz Gunung Serapi) & Wai FM Bidayuh/Radio Kayan (106.1MHz Gunung Serapi)
2. Hot FM 94.3MHz Gunung Serapi
3. Eight WuXian FM 98.3MHz Bukit Djin
4. Kool FM 104.3MHz Bukit Djin
5. Tea FM 102.7MHz Bukit Antu
6. Kupi-Kupi FM 92.5MHz Bukit Antu
7. Bernama Radio FM 100.9MHz Bukit Antu
==Radio reception results in Lingga, Sarawak==
1. Kupi-Kupi FM 92.5MHz is almost zero signal in Lingga.
2. Hot FM 94.3MHz and Kool FM 104.3MHz are the clearest Kuching radio stations in Lingga.
3. Eight WuXian FM 98.3MHz and Tea FM 102.7MHz are moderately weak.
==RTM Wai FM (Iban & Bidayuh/Kayan) coverage in Lingga, Sarawak==
In Lingga, same as Sebuyau, Simanggang and Maludam, Gunung Serapi transmitted Wai FM (Iban 101.3MHz and Bidayuh/Kayan 106.1MHz) are much clearer than Gunung Ampungan transmitter (Iban 106.9MHz and Bidayuh/Kayan 101.7MHz).
Hence, RTM Wai FM is tuned in Lingga, Sarawak via Gunung Serapi transmitter (Iban 101.3MHz and Bidayuh/Kayan 106.1MHz).
==Radio stations list in Lingga, Sarawak==
* RTM Radio Klasik FM 107.3MHz Bukit Temudok
* RTM Nasional FM 98.9MHz Bukit Temudok
* RTM Sarawak FM 100.3MHz Bukit Temudok
* RTM Traxx FM 103.8MHz Bukit Temudok
* RTM Ai FM 106.3MHz Bukit Temudok
* RTM Red FM 106.3MHz Bukit Temudok
* RTM Sri Aman FM 89.5MHz Bukit Temudok
* RTM Sibu FM 94.6MHz Bukit Kayu Malam Sarikei (weak)
* Cats FM 88.7MHz Bukit Temudok
* Hot FM 94.3MHz Gunung Serapi Kuching
* Kupi-Kupi FM 92.5MHz Bukit Djin Kuching (super weak)
* Eight FM 98.3MHz Bukit Djin Kuching (weak)

* RTM Wai FM Iban 101.3MHz Gunung Serapi Kuching (weak)
On 8th November 2026, I pay a visit to Sarawak again after 1 year hiatus, but today I visit Lubok Antu and Lingga in Sri Aman Division to conduct radio DXpedition.
In Lubok Antu, I could only receive these radio stations from Bukit Temudok tower, but weaker signal.
* Cats FM 88.7MHz
* RTM Radio Klasik FM 107.3MHz
* RTM Nasional FM 98.9MHz
* RTM Sarawak FM 100.3MHz
* RTM Traxx FM 103.8MHz
* RTM Ai FM 105.3MHz
* RTM Red FM 106.3MHz
* RTM Sri Aman FM 89.5MHz
Distance is 43km from Bukit Temudok to Lubok Antu.
RTM has Lubok Antu gap filler transmitter which operates Nasional FM 97.0MHz and Sarawak FM 98.4MHz. Although their signal are good, but audio quality of 97.0MHz and 98.4MHz are poor because they are too soft.
No signal of tuning RTM Wai FM Bidayuh (106.1MHz & 101.7MHz), Wai FM Iban (101.3MHz & 106.9MHz) and Hot FM 94.3MHz in Lubok Antu, Sarawak.
Radio Republik Indonesia RRI Sintang PRO-1 FM 102.5MHz (also on FM 95.0MHz from Badau repeater) is the only Indonesia radio station available in Lubok Antu, Sarawak, Malaysia with weak signal condition.
No signal to tune RRI Sintang PRO-2 FM 90.7MHz and PRO-3 FM 96.6MHz due to lower power transmission.
KL FM 97.2MHz ialah sebuah stesen radio tempatan/negeri yang dikendali oleh Radio Televisyen Malaysia (RTM), ia dipancar dari Menara Kuala Lumpur, meliputi Wilayah Persekutuan Kuala Lumpur dan Selangor (kecuali Rawang, Sabak Bernam dan Daerah Hulu Selangor). RTM KL FM 97.2MHz juga boleh didengari di sebahagian Negeri Sembilan seperti Nilai, Seremban, Port Dickson dan Rembau.
KL FM 97.2MHz is a regional radio station operated by Radio Televisyen Malaysia (RTM), transmitted from Kuala Lumpur Tower, covering Federal Territory of Kuala Lumpur and Selangor (except Rawang, Sabak Bernam and Hulu Selangor District). This radio station is also available on the same frequency in part of Negeri Sembilan such as Nilai, Seremban, Port Dickson and Rembau.
Dari tahun 2019 sehingga 2025, saya membuat rakaman video penerimaan siaran radio KL FM 97.2MHz di beberapa kawasan Negeri Sembilan.
From 2019 to 2025, I made the radio reception videos of KL FM 97.2MHz in several areas of Negeri Sembilan.
1. Seremban (55km)
2. Port Dickson (71km)
3. Mantin (42km)
4. Rembau (77km)
5. Kota (88km)
6. Pedas Linggi (89km)
7. Bukit Pelanduk (56km)
Tiada isyarat boleh diterima di Daerah Jelebu, Jempol, Tampin dan Kuala Pilah.
No signal is received in Jelebu, Jempol, Tampin and Kuala Pilah Districts.
Siaran radio KL FM 97.2MHz boleh didengari dengan isyarat lemah di sebahagian kecil Melaka (Kuala Sungai Baru, 96km dari pemancar Menara Kuala Lumpur).
KL FM 97.2MHz can be tuned weakly in small part of Melaka (Kuala Sungai Baru, 96km from KL Tower)
It is almost 1 year anniversary of Kool FM expanding coverage in Ipoh, Melaka and Johor Bahru by taking over frequencies from Eight WuXian (formerly known as Eight FM).
Currently both radio stations broadcast in Klang Valley, Eight WuXian is on FM 88.1MHz, then Kool FM is on 101.3MHz, but they are transmitted from different locations. Eight WuXian FM 88.1MHz is transmitted from Gunung Ulu Kali, meanwhile Kool FM 101.3MHz is transmitted from Bukit Sungai Besi, hence both have different coverage.
Technically FM 101.3MHz can be transmitted from Gunung Ulu Kali as it has met the minimum frequency separation with existing radio stations.
If Kool FM moves its transmitter site of Klang Valley frequency 101.3MHz from Bukit Sungai Besi to wider coverage Gunung Ulu Kali with MCMC's approval, then it can swap its frequency with Eight WuXian FM 88.1MHz, which means that Kool FM is on 88.1MHz and Eight WuXian is on FM 101.3MHz,
==For Kool FM==
1. The frequency FM 88.1MHz in Gunung UIu Kali and Gunung Ledang will be same radio station again, so it becomes self-interference in Negeri Sembilan and part of Pahang.
2. While Gunung Telapak Buruk has no vacant frequency for Kool FM, actually Kool FM can launch Seremban frequency by taking over 88.3MHz from Eight WuXian which is transmitted from Bukit Gun, but small coverage. When Kool FM 88.3MHz from Bukit Gun cannot be tuned outside Seremban, the listeners can switch to 88.1MHz in rest of Negeri Sembilan areas under self-interference basis as both transmitters from Gunung Ulu Kali and Gunung Ledang are under Kool FM, just like what happened under One FM and 8FM era from 1st January 2009 to 26th October 2025.
(Current)
88.1MHz: Eight WuXian Gunung Ulu Kali
88.1MHz: Kool FM Gunung Ledang
<Co-channel interference in Negeri Sembilan>
(Proposed)
88.1MHz: Kool FM Gunung Ulu Kali
88.1MHz: Kool FM Gunung Ledang
<Self interference in Negeri Sembilan>
==For Eight WuXian==
1. Eight WuXian can make a comeback in Melaka via overspill signal from Gunung Ulu Kali on FM 101.3MHz. Hence, Eight WuXian FM 101.3MHz from Gunung Ulu Kali can be tuned in Kuala Lumpur, Selangor, South Perak, West Pahang, part of Negeri Sembilan and part of Melaka like BFM 89.9 and GoXUAN FM 88.9MHz. Technically, Eight WuXian FM 101.3MHz can be tuned from Lubok Cina to Tanjung Kling in Melaka, despite its Melaka frequency 88.1MHz is now taken over by Kool FM.
With such suggestions above, it is a win-win situation for Kool FM and Eight WuXian. First, Kool FM solves its co-channel interference issue in Negeri Sembilan by swapping frequency with Eight WuXian in Gunung Ulu Kali. Secondly, Eight WuXian can return to Melaka again if 101.3MHz is taken by Eight WuXian and transmitted from Gunung Ulu Kali. Hence, both radio stations can gain more clients (advertisers) and listeners.
==Results==

Sedili is a small town located on the east coast in Kota Tinggi District of Johor, it is 38km away from Kota Tinggi town.
Regarding the radio stations availability, RTM (Radio Televisyen Malaysia) has a low power gap filler transmitter in Telekom Tanjung Sedili tower for two of its radio stations, such as Radio Klasik FM 100.5MHz and Nasional FM 96.5MHz to cover the blindspot coverage of Bukit Tinggi and Gunung Pulai transmitters.
What about Gunung Pulai transmitted Johor Bahru radio reception in Sedili, Johor?
Personally I plan to have radio DXpedition in Sedili, Johor during Hari Raya Aidiladha 2027 in mid of May 2027 under day trip basis. From my home in Balakong to this location, it takes about 4 hours 30 minutes which is longer than reaching Johor Bahru, Mersing and Pontian. Sedili is the furthest location in Johor when I reach there from my home in Balakong, Selangor.
Balakong >> Johor Bahru: 3 hours 30 minutes
Balakong >> Mersing: 4 hours 5 minutes
Balakong >> Sedili: 4 hours 30 minutes
Balakong >> Pontian: 3 hours 30 minutes
(Direct traveling only, excluding break and meals)
Originally I plan to come there on 1st January 2027, but I concern about the flood disaster there due to northeast monsoon season. Coincidentally my friend, Rafiq went to Sedili for fishing yesterday afternoon, hence he also conducted frequency check there by tuning some radio stations from Gunung Pulai and Singapore. Then, he uploads the videos to his YouTube channel.
Here are the radio reception videos in Sedili, Johor by Rafiq.
==Commercial radio stations from Gunung Pulai tuned in Sedili, Johor (random)==
1. Raaga FM 103.7MHz
2. Mix FM 99.1MHz
3. Lite FM 94.6MHz
4. MY FM 95.4MHz
5. Best FM 104.1MHz
Result: All are still clear in Sedili, Johor.
==RTM radio stations reception in Sedili, Johor==
1. Radio Klasik
100.5MHz is transmitted from TM Tanjung Sedili. 106.7MHz (Gunung Pulai) is still clear, but 93.6MHz (Gunung Ledang) is weak, meanwhile 90.1MHz (Bukit Tinggi) has co-channel interference with Hot FM 90.1MHz from Gunung Pulai in Sedili.
2. Nasional FM
96.5MHz is transmitted from TM Tanjung Sedili. 105.7MHz (Gunung Pulai) and 90.9MHz (Bukit Tinggi) are still clear in Sedili, but 96.6MHz (Gunung Ledang) is not receivable due to 96.5MHz from Tanjung Sedili transmitter.

==Singapore radio stations (Bukit Batok) tuned in Sedili, Johor==
1. Mediacorp Warna 94.2FM
2. Mediacorp Ria 89.7FM
3. Mediacorp Oli 96.8FM
4. SPH One FM 91.3
Based on the videos above, Gunung Pulai transmitted radio stations are still clear in Sedili, Johor, except Hot FM 90.1MHz, Fly FM 102.5MHz, Zayan FM 92.8MHz and Melody FM 98.4MHz.
- Hot FM 90.1MHz has co-channel interference with RTM Radio Klasik 90.1MHz from Bukit Tinggi transmitter
- Fly FM 102.5MHz has co-channel interference with Best FM 102.5MHz from Bukit Tinggi transmitter
- Zayan FM 92.8MHz has adjacent channel interference with RTM Traxx FM 92.9MHz from Bukit Tinggi transmitter
- Melody FM 98.4MHz has weak signal in Sedili.
RTM radio stations from Bukit Tinggi are still clear in Sedili, except Radio Klasik FM 90.1MHz, meanwhile Gunung Ledang signal is weak there.
Compare with other RTM radio stations from Gunung Ledang, Asyik FM 95.6MHz is the weakest in Sedili as it only operates 0.25kW transmitter power in Gunung Ledang.
In addition, Singapore radio stations are also receivable in Sedili, Johor, except Kiss 92FM due to RTM Johor FM 92.1MHz. According to Rafiq, all Mediacorp radio stations are loud and clear there, but SPH (Singapore Press Holdings) radio stations are weak in Sedili, Johor. Hao FM 96.3MHz and UFM 100.3 are interfered by RTM Nasional FM 96.5MHz and Radio Klasik FM 100.5MHz from Tanjung Sedili transmitter respectively.
As Sedili is a Malay majority small town in Kota Tinggi District of Johor, the people can tune two Malay radio stations (Ria 89.7FM and Warna 94.2FM) from Singapore loudly and clearly, alongside local radio stations.
In conclusion, Gunung Pulai and Singapore radio stations are still available in Sedili, Johor.
