RTM Pahang FM should be changed its Muadzam Shah frequency from 88.0MHz to 103.9MHz due to adjacent channel interference with RTM Radio Klasik FM 87.9MHz from Gunung Telapak Buruk in Muadzam Shah, Pahang

 

 

RTM Pahang FM has local tuning frequency in Muadzam Shah on FM 88.0MHz, transmitted from Bukit Sembilan.

 

On 18th September 2022, I traveled to Muadzam Shah to conduct radio check and make radio signal content videos.

 

Pahang FM 88.0MHz from Bukit Sembilan reception is very bad in Muadzam Shah actually because it is often being interfered by RTM Radio Klasik FM 87.9MHz from Gunung Telapak Buruk, meanwhile it is also interfered by 8FM 88.1MHz from Gunung Ledang in several locations of Muadzam Shah.

 

In my opinion, Bukit Sembilan transmitter site is quite strategic and its coverage is quite good to cover Muadzam Shah and Keratong, as well as part of Kuala Rompin, but interference of Pahang FM 88.0MHz is actually caused by frequency problem.

 

Technically, Bukit Sembilan frequency should be separated from Gunung Telapak Buruk and Gunung Ledang at least 300kHz, meanwhile Gunung Ulu Kali and Bukit Pelindung are minimum 200kHz.

 

I did try other frequencies in Muadzam Shah, all of them are unstable and weak.

 

* FM 88.0MHz (Bukit Sembilan 19km): Adjacent channel interference with RTM Radio Klasik FM 87.9MHz from Gunung Telapak Buruk

 

* FM 104.1MHz (Bukit Pelindung 92km): Co-channel interference with Best FM 104.1MHz from Gunung Ulu Kali

 

* FM 95.5MHz (Bukit Sulai 72km): Adjacent channel interference with Asyik FM 95.6MHz from Gunung Ledang

 

* FM 107.5MHz (Gunung Ulu Kali 149km): Signal is stable, but not clear (MONO reception)

 

Radio reception of all stated Pahang FM frequencies was conducted exactly at Dataran Bandar Muadzam Shah where located at the town center of Muadzam Shah, Pahang.

To resolve the interference issue, I highly suggest RTM to change Pahang FM's Muadzam Shah frequency. Based on frequency bandscan, there are four available frequencies which suitable for Bukit Sembilan transmission, such as:

- FM 99.1MHz

- FM 102.0MHz

- FM 103.9MHz

- FM 105.5MHz

==RF analysis==

A. FM 99.1MHz

98.9MHz: Zayan FM Gunung Ledang

99.1MHz: Pahang FM Bukit Sembilan (0.5kW)

<200kHz, OK in Muadzam Shah, but interference in Felda Selancar>

 

99.1MHz: Pahang FM Bukit Sembilan (0.5kW)

99.3MHz: Raaga Gunung Ulu Kali

<200kHz, OK>

 

99.1MHz: Pahang FM Bukit Sembilan (0.5kW)

99.5MHz: Hot FM Gunung Telapak Buruk

<400kHz, OK>

 

99.1MHz: Pahang FM Bukit Sembilan (0.5kW)

99.1MHz: Mix FM Gunung Pulai

<0kHz, OK>

 

B. FM 102.0MHz

101.8MHz: MY FM Gunung Ulu Kali

102.0MHz: Pahang FM Bukit Sembilan (0.5kW)

<200kHz, OK>

 

102.0MHz: Pahang FM Bukit Sembilan (0.5kW)

102.2MHz: Pahang FM Bukit Fraser

<200kHz, OK>

102.0MHz: Pahang FM Bukit Sembilan (0.5kW)

102.3MHz: Melaka FM Gunung Ledang

<300kHz, OK>

 

C. FM 103.9MHz

103.6MHz: Era FM Gunung Telapak Buruk

103.9MHz: Pahang FM Bukit Sembilan (0.5kW)

<300kHz, OK>

 

103.9MHz: Pahang FM Bukit Sembilan (0.5kW)

104.1MHz: Pahang FM Bukit Pelindung

<200kHz, OK> (same radio station)

 

103.9MHz: Pahang FM Bukit Sembilan (0.5kW)

104.1MHz: Best FM Gunung Ulu Kali

<200kHz, OK>

 

103.8MHz: Manis FM Bukit Senggora (Maran sahaja)

103.9MHz: Pahang FM Bukit Sembilan (0.5kW)

<100kHz, OK>

 

103.9MHz: Pahang FM Bukit Sembilan (0.5kW)

104.3MHz: Hot FM Gunung Ledang

<400kHz, OK>

 

D. FM 105.5MHz

105.3MHz: Johor FM Gunung Ledang

105.5MHz: Pahang FM Bukit Sembilan (0.5kW)

<200kHz, OK in Muadzam Shah, but interference in Felda Selancar>

 

105.5MHz: Pahang FM Bukit Sembilan (0.5kW)

105.7MHz: Lite FM Gunung Ulu Kali

<200kHz, OK>

 

Based on RF analysis, FM 103.9MHz is the most suitable frequency for RTM Pahang FM Bukit Sembilan transmission because it is having 300kHz frequency separation with Era FM 103.6MHz from Gunung Telapak Buruk, and 400kHz frequency separation with Hot FM 104.3MHz from Gunung Ledang which are very sufficient. In addition, despite Pahang FM 103.9MHz Bukit Sembilan transmission has 100kHz frequency separation with Manis FM 103.8MHz from Bukit Senggora, but it is ok because both are targeting different area. I don't think Pahang FM 103.9MHz Bukit Sembilan transmission can overspill to Maran, Jengka, Chenor, Bandar Bera and Temerloh.

FM 99.1MHz and FM 105.5MHz are less suitable for Bukit Sembilan transmission if covers Felda Selancar where is next to Johor border because Pahang FM could be interfered by Zayan FM 98.9MHz and Johor FM 105.3MHz from Gunung Ledang where both radio stations signal are very clear in between Muadzam Shah and Segamat.

In terms of transmission power, I also suggest RTM Pahang FM to increase transmitter power from 0.1kW to 0.5kW when Pahang FM Bukit Sembilan frequency changes to FM 103.9MHz. Correspondingly, Pahang FM 103.9MHz from Bukit Sembilan can reach Keratong, Bukit Ibam, Selancar and Bera Selatan. The reception of Pahang FM 103.9MHz in Keratong is expected to be clearer than FM 107.5MHz from Gunung Ulu Kali.

 

Other than Keratong, Muadzam Shah and Felda Selancar, several locations in Negeri Sembilan (Felda Palong and Serting Hilir) and Johor (Pemanis in Segamat) can receive Pahang FM 103.9MHz from Bukit Sembilan.

With the proposal of frequency change, it is not necessary to launch Gunung Ledang transmitter for Pahang FM to cover Muadzam Shah and Keratong where Gunung Ledang is located in Johor state.

 

Meanwhile in Keratong, Pahang FM can be tuned slightly clearer on 107.5MHz from Gunung Ulu Kali.

==My proposal of RTM Pahang FM Bukit Sembilan frequency change==

* Frequency: FM 103.9MHz

* Power: 0.5kW

* Coverage: Muadzam Shah, Bukit Ibam, Keratong, Selancar and Bera Selatan

Radio check (FM DX) in Muadzam Shah, Pahang.

 

In conjunction with Malaysia Day public holiday, I went to Muadzam Shah, Pahang for radio signal monitoring activity. Originally I planned to drop by there on 31st August 2022 during departure from Kuantan to Balakong, but it was too far to travel such routes. Hence, I chose to carry forward Muadzam Shah FM DXing to Malaysia Day holiday. So, I made decision to come on 18th September 2022, rather than 16th September 2022.

Few radio stations are taken sample of signal reception in Muadzam Shah, Pahang, such as:

1. Hot FM

 

4 frequencies can be received in Muadzam Shah. The clearest Hot FM frequency is FM 104.3MHz from Gunung Ledang, following by FM 99.5MHz Gunung Telapak Buruk and FM 97.6MHz Gunung Ulu Kali, meanwhile FM 92.4MHz from Bukit Pelindung is still receivable.

 

2. Asyik FM

 

I compare two frequencies reception in Muadzam Shah. FM 102.5MHz Gunung Ulu Kali and FM 95.6MHz Gunung Ledang are receivable there. In terms of signal reception, Asyik FM 102.5MHz from Gunung Ulu Kali is more stable than 95.6MHz from Gunung Ledang.

 

Asyik FM 95.6MHz from Gunung Ledang is clear, but unstable due to adjacent channel interference with Pahang FM 95.5MHz from Bukit Sulai which intends for Gambang, Sri Jaya, and Chini.

 

3. Pahang FM

 

None of frequencies are having clear and stable signal in Muadzam Shah. The local transmitter FM 88.0MHz from Bukit Sembilan is being interfered by RTM Radio Klasik FM 87.9MHz from Gunung Telapak Buruk badly, and interference with 8FM 88.1MHz from Gunung Ledang could be detected certainly. 

FM 95.5MHz from Bukit Sulai reception is unstable due to adjacent channel interference with Asyik FM 95.6MHz from Gunung Ledang.

FM 104.1MHz from Bukit Pelindung is having co-channel interference with Best FM 104.1MHz from Gunung Ulu Kali.

FM 107.5MHz from Gunung Ulu Kali is the most stable frequency, but weak reception in Muadzam Shah.

 

4. MY FM

 

Same goes to Hot FM, 4 frequencies are receivable. FM 106.4MHz Gunung Ledang is the clearest, following by FM 100.6MHz Gunung Telapak Buruk dan FM 101.8MHz Gunung Ulu Kali. 

 

FM 101.1MHz Bukit Pelindung is still receivable with unstable STEREO signal.

 

5. Best FM

 

FM 94.8MHz from Gunung Ledang is the clearest and most stable frequency, meanwhile FM 104.1MHz from Gunung Ulu Kali is having co-channel interference with Pahang FM 104.1MHz from Bukit Pelindung. 

6. Lite FM

 

My favorite radio station actually. FM 92.2MHz from Gunung Ledang is the clearest, meanwhile FM 104.6MHz Gunung Telapak Buruk and FM 105.7MHz from Gunung Ulu Kali signal reception are moderate. From Seremban to Muadzam Shah, I listened to Lite FM all the way on FM 104.6MHz.

 

7. 988 FM

 

FM 98.2MHz from Gunung Ledang is the clearest in Muadzam Shah.

8. THR Gegar FM 88.8MHz

 

Adjacent channel interference with Traxx FM 88.7MHz from Gunung Telapak Buruk is detected.

 

9. THR Raaga 

 

Among three tested frequencies, FM 99.7MHz from Gunung Ledang is the clearest, meanwhile FM 101.5MHz Gunung Telapak Buruk and FM 99.3MHz Gunung Ulu Kali are weak there.

 

10. Negeri FM

 

FM 107.7MHz Gunung Ledang is slightly clearer than FM 92.6MHz Gunung Telapak Buruk.

 

11. Johor FM

 

Although Johor FM 105.3MHz covers North Johor only, but it is the clearest RTM state radio station from Gunung Ledang received in Muadzam Shah, Pahang.

 

12. Melaka FM

 

Compare with Negeri FM 107.7MHz and Johor FM 105.3MHz reception in Muadzam Shah, RTM Melaka FM 102.3MHz is the weaker as its Gunung Ledang transmission mainly beams to west direction to cover Melaka.

 

13. 8FM (formerly known as One FM)

 

Signal is quite weak, minor adjacent channel interference with Pahang FM 88.0MHz Bukit Sembilan transmitter is detected in Muadzam Shah.

 

14. CityPlus FM 106.0MHz

Reception is moderate to clear in Muadzam Shah, but adjacent channel interference with Ai FM 106.1MHz from Bukit Pelindung can be detected in several areas.

Overall check, Gunung Ledang transmitted radio stations are the clearest in Muadzam Shah, following by Gunung Telapak Buruk. Several Gunung Ulu Kali transmitted radio stations are still clear in Muadzam Shah, mainly Lite FM 105.7MHz, Zayan FM 104.9MHz, and Minnal FM 96.3MHz.

All radio check aka FM DX was conducted and filmed in Dataran Bandar Muadzam Shah, Pahang where located exactly at the town center.

 

Regarding Singapore radio stations in Muadzam Shah and Keratong, I did try CNA 93.8FM, Kiss 92FM, and One FM 91.3, none of them were receivable.

==Radio transmission distance to Muadzam Shah==

* Gunung Ledang: 93km

* Gunung Ulu Kali: 149km

* Bukit Pelindung: 92km

* Gunung Telapak Buruk: 115km

* Bukit Sembilan: 19km

Radio Exterior De Espana SW 15520kHz from Noblejas, Spain received in Balakong, Selangor, Malaysia

 

Today is Malaysia public holiday, known as Malaysia Day which falls annually on 16th September. I took opportunity to stay overnight until midnight to perform shortwave DXing by receiving signal from Europe, but my primary target was actually to receive Radio Romania Antena Satelor LW 153kHz (failed).

 

While I couldn't receive any signal from Radio Romania Antena Satelor LW 153kHz in Malaysia between 0000-0100 hours (UTC+8), I did manage to receive several shortwave radio stations.

 

Alongside BBC World Service from Ascension Island, Radio Farda (transmitted from Germany and UK), as well as Radio Romania International, I tried to receive Radio Exterior De Espana on SW 15520kHz in Balakong, Selangor, Malaysia.

 

According to short-wave.info, none of radio stations are operating on SW 15520kHz and adjacent frequencies during the receiving time. Hence, I identified SW 15520kHz is Radio Exterior De Espana.

The signal was quite weak actually. In terms of distance, Radio Exterior De Espana SW 15520kHz becomes 2nd furthest shortwave radio station that I tuned at my receiving location in Balakong, Selangor State, Malaysia after BBC World Service from Ascension Island.

 

==My shortwave DX report of Radio Exterior De Espana==

* Frequency: SW 15520kHz

* Power: 200kW

* Transmission site: Noblejas, Spain

* Receiving site: Balakong, Selangor, Malaysia

* Distance: 11074km

* Receiving date/time: 16th September 2022 0055H (UTC+8)/15th September 2022 1655H (UTC)

* Language: Spanish

* Receiver: TECSUN PL-310ET

* SINPO: 13322

I received UK and Germany transmitted Radio Farda shortwave signal in Balakong, Selangor, Malaysia.

 

On yesterday 15th September 2022 between 2300-2330 hours (UTC+8), I managed to receive Persian language external radio station, Radio Farda which are transmitted from Europe continent in Malaysia by following shortwave frequencies below:

 

1. SW 12005kHz from Woofferton, United Kingdom (300kW)

2. SW 15690kHz from Biblis, Germany (100kW)

3. SW 17830kHz from Lampertheim, Germany (100kW)

 

Receiving location is in Balakong, Selangor, Malaysia.

 

Among 3 frequencies, all of them are having same signal quality, but Radio Farda SW 17830kHz and SW 15690kHz are slightly louder.

 

In terms of distance, Radio Farda on SW 12005kHz from Woofferton, United Kingdom is the furthest with the distance as much as 10723km after the BBC World Service from Ascension Island which is 12928km and Radio Exterior De Espana. 

 

It is my another shortwave radio signal catch from Europe after Romania, Moldova (Radyo Denge Welat), France (Radyo Denge Welat) and Germany (DW). 

 

Radio Farda is usually targeting Persian speaking countries, notably Iran and some countries from Central Asia.

 

Here is the reception report of Radio Farda that I received in Balakong, Selangor, Malaysia.

 

1. SW 12005kHz Woofferton, United Kingdom

- Distance: 10723km

- Receiving time: 2308 hours (UTC+8)

- SINPO: 42233 

2. SW 15690kHz Biblis, Germany

- Distance: 9985km

- Receiving time: 2311 hours (UTC+8)

- SINPO: 33333

3. SW 17830kHz Lampertheim, Germany

- Distance: 9983km

- Receiving date/time: 2315 hours (UTC+8)

- SINPO: 44333

 

BBC World Service from Ascension Island received in Balakong, Selangor, Malaysia on 17640kHz, 17830kHz and 21630kHz, it becomes the furthest shortwave radio station that I received in Malaysia with 12928km.

 

In Malaysia, BBC World Service English broadcast can be tuned via shortwave radio transmission from Kranji, Singapore in certain broadcast hours, meanwhile FM 88.9MHz is available in South Johor areas.

 

Just midnight on today 16th September 2022, from 0000-0100 hours (Malaysia time UTC+8) or 1600-1700 hours (UTC), I received three BBC World Service shortwave frequencies from Ascension Island, Atlantic Ocean.

 

Frequencies are: 

1. SW 17640kHz (115 degree angle)

2. SW 17830kHz (85 degree angle)

3. SW 21630kHz (55 degree angle)

 

All stated frequencies are transmitted at 125kW output power. Although the primary targeting coverage region of BBC World Service SW 17640kHz, 17830kHz and 21630kHz from Ascension Island is Central Africa, but it can overspill to Malaysia and other ASEAN countries.

 

 

Among three videos above, SW 21630kHz is the clearest frequency, following by SW 17640kHz, meanwhile SW 17830kHz is the weakest. These 3 frequencies are transmitted from same site, but propagation is different due to different antenna beaming direction angle.

 

Here I would like to rate the reception of BBC World Service Ascension Island frequencies that I received in Balakong, Selangor, Malaysia with SINPO code. (1 is poor, 5 is excellent)

 

- SW 17640kHz:  24323

- SW 17830kHz: 13322

- SW 21630kHz: 45444 

 

The transmission distance from Ascension Island to my receiving location in Balakong, Selangor, Malaysia where is just 20km from Kuala Lumpur is 12928km. In terms of receiving distance, I break my record again by tuning BBC World Service from Ascension Island in Malaysia.

 

After I received BBC World Service Ascension Island shortwave signal, I do issue the e-QSL from BBC.

Rakita FM 107.9MHz from Bukit Sungai Besi received in Temerloh, Pahang

 

Rakita FM 107.9MHz (formerly known as IM4U FM before 2019) is a Malay language young oriented radio station based in Kuala Lumpur, the transmission site is located in Bukit Sungai Besi, instead of Gunung Ulu Kali.

 

Transmitter power is likely 2kW. Coverage areas are mainly in Kuala Lumpur, and part of Selangor such as Kuala Langat, Ampang, Shah Alam, Klang, Kajang, Bangi, Sepang, Petaling Jaya, Selayang, Gombak, Kuala Selangor, Sekinchan, meanwhile signal is weak in North Selangor.

 

Outside of Klang Valley, Rakita 107.9 is available in part of Negeri Sembilan such as Nilai, Mantin, Port Dickson and part of Seremban, however Rakita FM 107.9MHz from Bukit Sungai Besi can be received unexpectedly in Temerloh, Pahang.

3 years ago, I was used to receive this radio station in Temerloh town, but I never managed to film the video actually. Over last month, with my Kuantan trip in end of August 2022, I did manage to record the receiving signal of Rakita FM 107.9MHz in Temerloh, Pahang. The filming location was not located in Temerloh town, but I recorded the video at a highway rest station in Temerloh (also known as RnR Temerloh) during the short break before arriving in Kuantan.

 

- Frequency: FM 107.9MHz

- Power: 2kW

- Transmission site: Bukit Sungai Besi, Kuala Lumpur

- Receiving location: RnR Temerloh Eastbound, 28000 Temerloh, Pahang 

- Distance: 93km

Receiving signal was MONO, recorded on 28th August 2022. Compare with Buletin FM 101.3MHz, the signal quality of Rakita FM 107.9MHz is slightly stronger in Temerloh, Pahang. I may think Rakita FM 107.9MHz is using 2kW transmitter, while Buletin FM 101.3MHz is 1kW or lower.

The signal reception of Rakita FM 107.9MHz in Temerloh is not strong as other radio stations because Rakita FM 107.9MHz is transmitted from Bukit Sungai Besi, rather than Gunung Ulu Kali. 

During IM4U FM era, I was used to propose to shift the transmission site to Gunung Ulu Kali due to wider coverage (and I have prejudice against Bukit Sungai Besi), but the proposal was not working at all and likely turned down by MCMC. I suspect Rakita FM 107.9MHz Gunung Ulu Kali transmission is not allowed by MCMC as the Gunung Ulu Kali transmission can overspill to several areas in Riau Province, Indonesia, somehow Rakita is on FM 107.9MHz which can led interference to Indonesia airband transmission. Hence, Rakita is only allowed to transmit in Bukit Sungai Besi to prevent overspilling the signal to Indonesia territories and led interference to Indonesia airband.

 

Pahang FM is the No.1 widest coverage RTM state radio station in Peninsular Malaysia

 

Among all RTM state radio stations in Peninsular Malaysia, Pahang FM is the no.1 widest coverage RTM state radio station in terms of coverage availability. 

 

This is because Pahang FM can be received in several states of Peninsular Malaysia outside Pahang via frequencies transmission. Here are the coverage of Pahang FM outside Pahang state:

 

1. Kuala Lumpur, Putrajaya & Selangor via FM 107.5MHz from Gunung Ulu Kali (weaker reception)

 

2. Part of Negeri Sembilan via FM 107.5MHz from Gunung Ulu Kali (weaker reception)

Available locations: Nilai, Mantin, Simpang Durian, Simpang Pertang, Serting Tengah, Jempol, Port Dickson, Linggi, and part of Seremban.

 

3. Part of Melaka via FM 107.5MHz from Gunung Ulu Kali (weaker reception and interference with Melody FM 107.3MHz and Negeri FM 107.7MHz from Gunung Ledang in certain locations)

 

Available in Kuala Sungai Baru, Masjid Tanah, Lubuk Cina, Tanjung Kling, Sungai Udang and part of Melaka City.

 

4. Central and South Perak via FM 107.5MHz from Gunung Ulu Kali and FM 100.3MHz from Gunung Brinchang (weaker reception)

5. Part of Johor via FM 91.9MHz from Kuala Rompin and FM 107.5MHz from Gunung Ulu Kali

Note: Batu Anam in Segamat District can receive Pahang FM 107.5MHz from Gunung Ulu Kali, but interference with Melody FM 107.3MHz and Negeri FM 107.7MHz from Gunung Ledang is occured.

 

6. Part of Kelantan (Gua Musang district) via FM 100.3MHz from Gunung Brinchang and FM 107.5MHz from Gunung Ulu Kali

Co-channel interference with Thailand radio station is detected in Gua Musang town on FM 107.5MHz.

 

7. Southern Terengganu via FM 104.1MHz from Bukit Pelindung  

Coverage is up to Kerteh and Paka.

 

Overall check that FM 107.5MHz, FM 100.3MHz and FM 104.1MHz are the frequencies which can overspill outside Pahang state, meanwhile low power FM 92.0MHz, FM 91.9MHz, and FM 102.2MHz can overspill too, but weaker than 107.5 and 104.1.
