RTM Traxx FM and Brunei's Kristal FM are using same frequency on 90.7MHz to target different coverage.
Traxx FM 90.7MHz from Lawa Mandau mainly covers Kota Kinabalu and West Coast Division of Sabah, meanwhile Kristal FM 90.7MHz covers Bandar Seri Begawan in Brunei, however Traxx FM 90.7MHz has co-channel interference with Kristal FM 90.7MHz in Kimanis, Sabah.
Alternatively, RTM Traxx FM can be tuned on 105.3MHz from Layang-Layang or 99.1MHz from Bukit Tampalagus in Kimanis, Sabah when 90.7MHz is interfered by Kristal FM.
Keningau is the largest town in Interior Division of Sabah. Regarding the radio stations availability, the listeners can only receive 7 RTM radio channels in this town, such as Radio Klasik FM 88.5MHz, Nasional FM 89.3MHz, Sabah FM 90.3MHz, Traxx FM 91.1MHz, Ai FM 92.3MHz, Sabah VFM 93.1MHz and Keningau FM 94.7MHz where they are transmitted from Bukit Sigapon, but Keningau FM has a transponder broadcast on FM 98.4MHz from Rumah Persekutuan Keningau, but can the listeners tune Kota Kinabalu radio stations in Keningau, Sabah?
Let's watch some videos of tuning Kota Kinabalu radio stations in Keningau, Sabah which are recorded by Kisah Alkisah recently.
In these videos, Kisah Alkisah tuned Era FM Sabah 102.4MHz, Hitz FM 100.8MHz, Bernama Radio FM 107.9MHz, Hot FM 87.7MHz, Eight FM 95.7MHz and Sinar FM 104.9MHz in Keningau, Sabah. According to this videos above, Kota Kinabalu radio stations (TX: Bukit Karatong) have no signal in Keningau town, Sabah. This is because Keningau is blocked by Crocker Mountains, so Bukit Karatong radio signal cannot transmit there.
In conclusion, Bukit Karatong transmitted Kota Kinabalu radio stations cannot be received in Keningau, Sabah, even no signal in Tambunan and Tenom too.
Several radio stations from Miri, Brunei and Limbang can be tuned in Tamparuli, Sabah, especially at the nighttime. According to Kisah Alkisah, the Sabah radio DXer, these radio stations are not receivable in Tamparuli during daytime reception.
The furthest radio stations tuned in Tamparuli, Sabah are Cats FM 93.3MHz and Era FM Sarawak where both are transmitted from Bukit Lambir.
The signal type of radio stations from Miri, Limbang and Brunei are tropospheric propagation in Tamparuli, Sabah.
1. RTB Pelangi FM 91.0MHz (258km from Andulau, Brunei)
2. RTB Nur Islam FM 94.9MHz (258km from Andulau, Brunei)
3. RTB Nasional FM 93.8MHz (258km from Andulau, Brunei)
Adjacent channel interference with IKIM FM 93.9MHz Bukit Karatong transmitter can be heard in Tamparuli, Sabah.
4. Cats FM 88.7MHz (208km from Bukit Mas, Limbang, Sarawak)
5. Era FM Sarawak 101.3MHz (332km from Bukit Lambir, Miri, Sarawak)
6. Cats FM 93.3MHz (332km from Bukit Lambir, Miri, Sarawak)
RTM Wai FM Bidayuh is now broadcasting 18 hours by extending its airtime from 12am to 6am.
Before this, Wai FM Bidayuh broadcasted from 6am to 12pm, then 6pm to 12am, meanwhile 12pm to 6pm is occupied by Radio Kayan. Then, it relayed RTM Sarawak FM from 12am to 6am.
From 8th June 2025, Wai FM Bidayuh adds 6 hours broadcast from 12am to 6am. So, Sarawak FM is no longer relayed on this radio station from 12am to 6am.
From 12am to 6am, Wai FM Bidayuh plays non-stop Bidayuh songs in automation mode without any DJs like what Wai FM Iban does.

In Tawau, only RTM radio stations (Radio Klasik, Nasional FM, Sabah FM, Traxx FM, Ai FM, Sabah VFM, Tawau FM & Sandakan FM), IKIM FM and RRI Nunukan PRO-1 (FM 96.3MHz/91.5MHz) are available there.
Era FM Sabah 103.0MHz, Hitz FM 99.8MHz, MY FM 100.6MHz, Melody FM 102.2MHz and Sinar FM 106.9MHz from Bukit Trig, Sandakan are not receivable in Tawau, Sabah.
2 years ago, MYTV added digital terrestrial television (DTT) transmitters in Gunung Telapak Buruk and TM Kangar to cover Negeri Sembilan and Perlis respectively.
For Gunung Telapak Buruk, MYTV supposedly launched there somewhere in 2018, but the plan was suspended due to dispute with Telekom Malaysia (TM). So, I was disappointed of MYTV for not launching DTT transmitters Gunung Telapak Buruk back then.
Before launching DTT transmitters in Gunung Telapak Buruk, MYTV was accessed via Bukit Tampin transmitter in Seremban, but not all locations could receive the signal from Bukit Tampin.
When I heard the news where Gunung Telapak Buruk would have DTT transmitters from MYTV, I was excited actually because I waited it for very long.
In September 2023, MYTV began DTT operations in Gunung Telapak Buruk, the frequencies are CH25/UHF 506MHz (MUX A) and CH23/UHF 490MHz (MUX B). I performed my very first DVB-T2 DXing of these frequencies at my home in Balakong, Selangor, then Beranang in Selangor where is not far from Mantin, Negeri Sembilan.
Today on 8th June 2025, I stop in Seremban, Negeri Sembilan for lunch and radio DXing after having long drive from Johor Bahru. Coincidentally, I bring my portable DVB-T2 television receiver together, so I take this opportunity to check MYTV DTT signal from Gunung Telapak Buruk in Seremban before driving back home.
As I'm using short length mobile TV antenna, the signal strength of MYTV DTT signal from Gunung Telapak Buruk is quite low (38-43) in Seremban, Negeri Sembilan.
Here are my videos of receiving MYTV digital terrestrial television from Gunung Telapak Buruk in Seremban, Negeri Sembilan.
On 23rd February 2025, I went to South Johor areas such as Kulai, Senai, Kota Tinggi, Skudai and Ulu Tiram to perform radio signal monitoring of Eight FM 105.3MHz and 88.1MHz under day trip.
After 3 months, I come to South Johor areas again to check the signal of Eight FM on 105.3MHz which is transmitted from Taman Sentosa, Johor Bahru, but different receiving locations. At this time, I make another 7 radio signal monitoring locations in South Johor, covering Johor Bahru, Pengerang, Pasir Gudang, Gelang Patah, Desaru, Bandar Penawar and Iskandar Puteri.
In Johor Bahru areas, we can tune many radio stations from local, Singapore and Batam, Indonesia. For Malaysia radio stations, most of Johor Bahru radio stations are transmitted from Gunung Pulai, but Eight FM 105.3MHz is the only JB radio station which is not transmitted from Gunung Pulai, instead JB town's Taman Sentosa tower. Hence, this makes me interested to monitor its signal in surrounding areas of Johor Bahru.
Melody FM is different case because it has Gunung Pulai transmitter on 98.4MHz, but it covers Kulai, Skudai, Senai, Pontian, Kota Tinggi, part of Johor Bahru and Central Johor, meanwhile 103.3MHz is a supplementary transmitter in Johor Bahru which is transmitted from Metropolis Tower to cover Johor Bahru City where 98.4MHz is less clear.
1. Johor Bahru
2. Pasir Gudang
3. Iskandar Puteri
4. Gelang Patah
5. Pengerang
6. Bandar Penawar
7. Desaru
By comparing my radio reception of this radio station where I recorded on 23rd February 2025, Eight FM 105.3MHz is clear in Johor Bahru, Senai, Skudai, Pasir Gudang, and Ulu Tiram, but it has ultra weak signal in Pengerang, Desaru and Bandar Penawar meanwhile Eight FM 105.3MHz has co-channel interference with RTM Johor FM 105.3MHz Gunung Ledang transmitter in Kulai, Iskandar Puteri and Gelang Patah.
In Gelang Patah and Iskandar Puteri, Eight FM 88.1MHz from Gunung Ledang is clearer than 105.3MHz from Taman Sentosa.
Eight FM 105.3MHz has strong adjacent channel interference noise of Radio Republik Indonesia RRI Batam PRO-1 FM 105.1MHz in Pengerang, Johor.
Frankly, Eight FM 105.3MHz can be received in Bandar Penawar and Desaru weakly, despite its transmitter power is just 0.05kW because Eight FM is using directional antenna and the signal is beaming to northeast direction from Taman Sentosa. So, Bandar Penawar and Desaru are the furthest coverage of Eight FM 105.3MHz JB frequency from Taman Sentosa transmission tower.
繼2025年2月23日在柔佛南部的5個地區 (士乃Senai, 古來Kulai, 哥打丁宜 Kota Tinggi, 烏魯地南Ulu Tiram, 和士姑來Skudai)探測Eight FM 105.3MHz訊之後, 我今天又來到另外5個JB新山附近地區探測這家電台的訊號, 地區涵蓋了新山 Johor Bahru, 巴西古當Pasir Gudang, 伊斯干達公主城 Iskandar Puteri，振林山 Gelang Patah和邊佳蘭 Pengerang.
1. 新山 Johor Bahru
2. 巴西古當Pasir Gudang
3.伊斯干達公主城 Iskandar Puteri
4. 振林山 Gelang Patah
5. 邊佳蘭 Pengerang
6. Bandar Penawar
7. Desaru
整體上, Eight FM 105.3MHz在新山, 伊斯干達公主城, 和巴西古當可以收到很清楚的訊號, 但是聽眾是無法在邊佳蘭地區通過105.3來收聽Eight FM因為其發射站Taman Sentosa是不能覆蓋該地, 加上105.3被印尼電台105.1干擾。
Desaru和Bandar Penawar 一帶可以收到很弱的訊號。
Eight FM 105.3MHz在Iskandar Puteri 和 Gelang Patah一帶的線路比較差，在部分地區受到柔佛北部Johor FM同頻率干擾，但聽眾還可以通過88.1繼續收聽Eight FM。
88.1在Iskandar Puteri 和Gelang Patah是比105.3清楚些。
整體上Eight FM 105.3MHz的發射天線是對東北比較多，所以Desaru和Bandar Penawar 可以收到這家電台。如果從Senai去Desaru的路段，105.3從Masai可以聽到Bandar Penawar 收費站去。
RTM Sandakan FM is a Sabah local radio station for Sandakan Division, it broadcasts on the frequency 90.1MHz, transmitted from Bukit Trig. RTM Sandakan FM 90.1MHz covers Sandakan, Kinabatangan, Pamol, Telupid and Beluran, but it can be tuned in Lahad Datu on the same frequency.
Beyond Lahad Datu, RTM Sandakan FM 90.1MHz from Bukit Trig can be received moderately in Tawau Division too.
Sabah radio DXer, Kisah Alkisah recently published the radio reception videos of tuning RTM Sandakan FM 90.1MHz in Tawau and Kunak.
1. Tawau (178-180km)
2. Kunak (130km)
By comparing with other Sandakan radio stations (example: Era FM Sabah 103.0MHz and Hitz FM 99.8MHz), RTM Sandakan FM 90.1MHz is clearer.
In Tawau and Kunak, the radio signal of RTM Sandakan FM 90.1MHz is moderately clear.
Overall, outside Sandakan Division, RTM Sandakan FM 90.1MHz is still available in Lahad Datu, Kunak, Tawau and Semporna. Both Sandakan FM and Tawau FM can cover the entire east coast region of Sabah.
Semporna is the most southeastern location in Sabah which is located in Semporna District of Tawau Division, Sabah.
Here is a list of available radio stations in Semporna, Sabah.
* RTM Radio Klasik FM: 87.9MHz (Gunung Silam)
* RTM Traxx FM: 90.5MHz (Gunung Silam)
* RTM Ai FM: 91.7MHz (Gunung Silam)
* RTM Sabah VFM: 92.6MHz (Gunung Silam)
* RTM Nasional FM: 89.1MHz (Bukit Kemiri)
* RTM Sabah FM: 91.1MHz (Bukit Kemiri)
* RTM Tawau FM: 88.3MHz (Bukit Kemiri)
* RTM Sandakan FM: 90.1MHz (Bukit Trig)
* IKIM FM: 107.3MHz (Gunung Silam)
* RTM Wai FM: SW 11665kHz (RTM Kajang, Selangor)
* Radio Republik Indonesia RRI Nunukan PRO-1 FM 96.3MHz (Nunukan)/91.5MHz (Sebatik Island)
According to Sabah radio DXer, Kisah Alkisah, Astro radio stations from Sandakan's Bukit Trig like Era FM Sabah 103.0MHz, Hitz FM 99.8MHz, Melody FM 102.2MHz, Sinar FM 106.9MHz and MY FM 100.6MHz cannot be received in Semporna, even in Tawau.
In Semporna, RTM radio stations are mostly covered by Gunung Silam transmitter, but RTM launched the gap filler transmitter in Bukit Kemiri for 3 radio stations (Nasional FM, Sabah FM and Tawau FM) to cover Semporna clearly. Before this, these radio stations were tuned in Semporna via Gunung Silam transmitter before launching of Bukit Kemiri transmitter in 2017 by following frequencies below.
1. RTM Nasional FM 88.7MHz
2. RTM Sabah FM 89.7MHz
3. RTM Tawau FM 93.6MHz
Next, for IKIM FM, this Islamic radio station is tuned in Semporna, Sabah on 107.3MHz from Gunung Silam, meanwhile 100.7MHz from Gunung Andrassy signal is weak there. Comparing both frequencies, IKIM FM 107.3MHz is clearer than 100.7MHz in Semporna, Sabah.
Same as Tawau, radio stations from Indonesia (Nunukan) can be tuned in Semporna, Sabah, Malaysia, Radio Republik Indonesia RRI Nunukan PRO-1 can be tuned clearly on FM 96.3MHz there, but FM 91.5MHz Sebatik Island relay can be tuned in Semporna too with adjacent channel interference noise of RTM Ai FM 91.7MHz from Gunung Silam transmitter.
RTM Wai FM on SW11665kHz can be tuned moderately in Semporna, Sabah because the transmission from RTM Kajang beams the signal to entire Borneo Island, so this makes Wai FM SW 11665kHz available in entire Sabah and Sarawak region.
==Radio stations signal monitoring videos in Semporna, Sabah by Kisah Alkisah==
In Sarawak, Hot FM broadcasts only in Kuching on 94.3MHz, transmitted from Gunung Serapi, it is also receivable in Saratok District of Betong Division, part of Sri Aman and Serian.
Two weeks ago, I had managed to receive Hot FM 94.3MHz signal in 6 areas of Sarawak such as Simanggang, Engkilili, Pakan, Debak, Roban and Saratok, but recently the Bintulu radio DXer, Shafik1995 tuned Hot FM in Bintulu, Sarawak on the frequency 99.5MHz from Gunung Telapak Buruk, Negeri Sembilan on 30th May 2025.
The signal of Hot FM 99.5MHz was clear with statics in Bintulu, Sarawak without the adjacent channel interference noise of local radio station (Ai FM 99.3MHz from Bukit Setiam).
Hot FM 99.5MHz Gunung Telapak Buruk transmitter radio reception in Bintulu, Sarawak which received on 30th May 2025 was an overspill signal in Sporadic E propagation.
There was no adjacent channel interference noise of RTM Ai FM 99.3MHz Bukit Setiam transmitter when tuned to Hot FM 99.5MHz in Bintulu, Sarawak because:
1. The sensitivity of the radio receiver by Shafik1995 is very high, it can eliminate the interference noise of the adjacent station. At 100kHz frequency separation between distant and local radio stations, certain radio receivers have no interference at all.
2. Bukit Setiam is located in Tatau, Sarawak. It is 26km to Bintulu town. Hence, there is no obvious interference noise, but if we tune to Hot FM 99.5MHz Sporadic E signal from Gunung Telapak Buruk in the vicinity of Bukit Setiam, surely we will hear the interference noise.
3. Inversely if RTM Ai FM 99.3MHz is transmitted from Bukit Nyabau, instead of Bukit Setiam, I think Shafik1995 would detect the interference noise of this radio station when he tuned Hot FM 99.5MHz in Bintulu, Sarawak.
==Hot FM 99.5MHz Gunung Telapak Buruk radio reception in Bintulu, Sarawak==
* Frequency: FM 99.5MHz
* Power: 2kW
* Transmitter site: Gunung Telapak Buruk, Negeri Sembilan
* Receiving site: Bintulu, Sarawak
* Distance: 1221km
* Receiving date/time: 30th May 2025 1508 hours (UTC+8)
* Receiver: Clarion (Tuner IC Sanyo LA1863+LA1175) [ANALOG PLL]
* Antenna type: Electronic windscreen antenna
* Propagation type: Sporadic E
Before this, Shafik1995 also received Hot FM in Bintulu on 104.5MHz from Gunung Kledang (Ipoh) and 90.5MHz from Bukit Larut (Taiping) via Sporadic E propagation.
RTM Ai FM operates on the frequency 93.6MHz in Bukit Kayu Malam for Sarikei, Roban and Saratok, but Nasional FM is also using same frequency in Off Spaoh transmitter for Spaoh, Betong and Debak.
When both radio stations are using same frequency, despite different targeting location, there is co-channel interference on FM 93.6MHz in certain areas.
Between Saratok to Debak, RTM Ai FM 93.6MHz from Bukit Kayu Malam and Nasional FM 93.6MHz from Off Spaoh have co-channel interference in several areas such as Mendas and Kedap.
The co-channel interference between Ai FM and Nasional FM does not affect the listeners to tune the radio broadcast in the interference areas because both Ai FM and Nasional FM can be tuned via Bukit Temudok transmitter.
In Mendas and Kedap,
* Ai FM can be tuned clearly on 105.3MHz from Bukit Temudok
* Nasional FM can be tuned clearly on 98.9MHz from Bukit Temudok
The radio reception of Ai FM on 96.0MHz from Off Spaoh transmitter and Nasional FM on 90.3MHz from Bukit Kayu Malam are not clear in Mendas and Kedap, compared to 105.3MHz and 98.9MHz from Bukit Temudok.
RTM Radio Klasik in Mukah and Cats FM in Bintulu (Bukit Setiam) are using same frequency on 88.3MHz. As Bukit Setiam radio signal can reach Mukah Division, so this causes the co-channel interference between Radio Klasik and Cats FM in the areas between Mukah and Balingian.
However, the co-channel interference between Radio Klasik (Mukah) and Cats FM (Bukit Setiam Bintulu) on FM 88.3MHz in Balingian, Penipah and Matadeng does not affect the radio coverage at all because both parties have alternative frequencies where the listeners can tune clearly in affected areas.
==Alternative frequencies in Mukah Division when Radio Klasik and Cats FM have co-channel interference on FM 88.3MHz==
* Cats FM: 97.9MHz from Mukah or 99.9MHz from Bukit Singgalang
* RTM Radio Klasik: 87.9MHz from Bukit Setiam or 93.3MHz from Bukit Singgalang
For RTM Radio Klasik, when its Mukah frequency 88.3MHz has co-channel inteference from Penipah (Mukah outskirt) to Balingian, it can be tuned even clearly on 87.9MHz which is transmitted from Bukit Setiam.
