Another new FM DXing record in Malaysia: A Vietnam FM radio station on FM 93.1MHz is received in Kota Bharu, Kelantan, Malaysia

As we notice that North Kelantan (Kota Bharu) can receive many Thailand radio stations from Yala (Khao Pokyo), Sungai Golok, Sungai Padi, Tak Bai and Narathiwat, meanwhile the furthest Thailand radio station that can be received in Kota Bharu is from Pattani.

Break the records.

The FM radio reception for this time is beyond Thailand radio station in Kota Bharu. Kelantan YouTuber Senn Lens receives a Vietnam FM radio station in Kota Bharu and Pasir Mas, Kelantan, Malaysia in the car, frequency is FM 93.1MHz.

Usually I only can receive Vietnam radio stations in Malaysia on AM/MW (mediumwave) or SW (shortwave) after evening. In the past, I was used to receive Voice of Vietnam AM stations in Malaysia such as VOV-1 711kHz, VOV-2 783kHz, VOV-4 873kHz and VOV-6 1242kHz from Can Tho, Vietnam.

It is very strange when Vietnam FM radio station can be received in Malaysia (Kota Bharu, Kelantan) because FM radio station propagation is limited to maximum 130 to 200km usually.

 

According to these videos, I check Vietnam radio stations database which assign on the frequency FM 93.1MHz, the nearest station is An Giang Radio and Television aka ATV FM 93.1MHz from An Giang Radio and Televison transmitter tower, Vietnam (62km from Can Tho). 

An Giang Radio and Television

An Giang is located in southern Vietnam, not far from Cambodia border and South China Sea.

Technically, there is no any terrains between An Giang, Vietnam and Kota Bharu, Malaysia, therefore An Giang Radio FM 93.1MHz from An Giang, Vietnam can be received in Kota Bharu and Pasir Pekan, Kelantan, Malaysia.

==Distance of An Giang Radio FM 93.1MHz to Malaysia==

1. Kota Bharu: 592km
2. Pasir Pekan: 592km

==SINPO code==
1. Kota Bharu: 35333
2. Pasir Pekan: 23422

RF analysis: Can FM 102.75MHz be used for community radio station in Satun, Thailand?

Few years ago, there was a now defunct Thailand radio station in Satun, Idea Radio operated on 102.5MHz (later 102.6MHz). As Thailand standard FM frequency allocation is 250kHz per channel from 87.5 to 108.0, but this was second frequency allocation which did not follow Thailand standards, after FM 99.1MHz in Narathiwat.

If I follow current Thailand FM radio frequency allocation which is 250kHz per channel, as 102.5MHz is not suitable to be used in Satun main transmitter site as interference from Raaga FM 102.4MHz Gunung Jerai Malaysia, actually FM 102.75MHz can be used in Satun province for community radio station, but low power and not to use main site like public broadcasters transmit from Khuan Khan.

As FM 102.75MHz is not far from Perlis FM 102.9MHz Padang Pauh which separated at 150kHz, so FM 102.75MHz is not suitable to be used in Amphoe Mueang Satun due to interference, but this frequency can be used in other districts within Satun province, Thailand which a bit further from Perlis, Malaysia.

FM 102.75MHz radio transmission can be used in this transmission location below, but only select either one districts:

1. La-Ngu
2. Manang
3. Khuan Kalong
4. Tha Phae

To avoid interference to Perlis FM 102.9MHz Padang Pauh coverage in Perlis, Malaysia, the maximum transmitter power is 500W for FM 102.75MHz Satun radio transmission (Transmitter site: La-Ngu, Manang, Khuan Kalong or Tha Phae). 

If FM 102.75MHz is transmitted from Thung Wa, it is not suitable because it can interfere 4th Army Radio FM 103.0MHz Trang in Palian district which is high power transmission. In addition, FM 102.75MHz may be interfered by FM 103.0MHz Trang in some Thung Wa district. 

102.75MHz: Thung Wa FM 
103.0MHz: 4th Area Army Radio TP4FM Trang
<250kHz>

==RF analysis of FM 102.75MHz in Satun province==

1. Amphoe Mueang Satun (including Khuan Khan)

102.75MHz: Amphoe Mueang Satun FM
102.9MHz: Perlis FM Padang Pauh
<150kHz, NOT OK>

2. Manang/La-Ngu/Khuan Kalong/Tha Phae

102.75MHz: Thailand FM (Transmission site either Manang/La-Ngu/Khuan Kalong/Tha Phae)
102.9MHz: Perlis FM Padang Pauh
<150kHz, OK>

102.75MHz: Thailand FM (Transmission site either Manang, La-Ngu, Khuan Kalong, or Tha Phae)
103.0MHz: TP4FM Trang
<250kHz, OK>

94PFM We Love Satun (Thailand) received in Alor Setar, Kedah, Malaysia

In Alor Setar and Kuala Kedah, when RTM Mutiara FM 93.9MHz Gunung Jerai receiving signal goes weak, actually there is a Thailand radio station that I received there on the frequency next to Mutiara FM 93.9MHz. FM 94.0MHz has three radio stations within Southern Thailand where nearby Malaysia border, 94PFM We Love Satun from Satun, 94FM Club from Hatyai and True Love Kolok Radio from Sungai Golok.

I received 94PFM We Love Satun in Alor Setar, Kedah, Malaysia when Mutiara FM 93.9MHz Gunung Jerai signal goes weak.

For your information, Mutiara FM 93.9MHz Gunung Jerai does not cover Alor Setar and most of Kedah areas, it only targets blind spot areas of FM 95.7MHz Bukit Penara in North Penang Island such as Batu Feringghi, Tanjung Bungah, Teluk Bahang and Tanjung Tokong.

In Alor Setar, 94PFM We Love Satun FM 94.0MHz is receivable, but it is not clear and having a bit interference with Mutiara FM 93.9MHz Gunung Jerai each other.

- Frequency: FM 94.0MHz 

- Power: 0.5kW 

- Transmission site: Tirasathit Alley, Tambon Phiman, Amphoe Mueang Satun, Thailand 

- Receiving site: Alor Setar, Kedah, Malaysia 

- Distance: 65km

Apart from MCOT Satun FM 93.25MHz and Radio Thailand Satun (FM 95.5MHz and FM 99.5MHz) where transmitted from Khuan Khan hill, but 94PFM We Love Satun is the only Satun town transmitted radio station which can be received in Alor Setar, Kedah weakly. 

Received Thailand radio stations in Kelantan, Malaysia, but Pattani is the furthest radio station received in Kelantan?

Kelantan is a state located northeast Peninsular Malaysia within east coast region, border with Thailand at north, Terengganu at east, Perak at west, and Pahang at south.

As it is located next to Thailand border, so people in North Kelantan are able to receive Thailand TV and radio stations easily. Kelantan is bordered to Narathiwat province of Thailand.

North Kelantan usually can receive Thailand radio stations from Narathiwat, Sungai Golok and Yala (Khao Pokyo), such as:

1. Radio Thailand Narathiwat FM 98.25MHz
2. Radio Thailand Sungai Golok FM 106.5MHz
3. MCOT Narathiwat FM 96.0MHz
4. Police Radio FM 88.25MHz Narathiwat
5. Khon Tak Bai Radio FM 88.75MHz (only in Tumpat)
6. Kolok FM 101.5MHz from Sungai Golok
7. Kor. Sor. Wor 6 FM 92.5MHz Sungai Padi
8. Voice of Navy FM 94.75MHz (KCS Radio) Narathiwat
9. Slang Phan Fa Narathiwat FM 96.75MHz
10. 912 Radio Station FM 99.1MHz Narathiwat
11. SV Sound Radio FM 107.0MHz Tak Bai
12. Radio Thailand Yala FM 92.0MHz, 94.25MHz and 95.0MHz
13. Radio Thailand Betong FM 93.0MHz
14. MCOT Yala FM 102.5MHz
15. Parliament Radio Station FM 89.0MHz Yala

Apart from Narathiwat, Tak Bai, Sungai Golok and Yala (Khao Pokyo), the furthest distant Thailand radio station that can be received in North Kelantan is from Pattani.

In the videos by Senn Lens on YouTube, FM 107.25MHz is the only Pattani transmitted Thailand radio station which available in part of North Kelantan. 

FM 107.25MHz is Mor Or Mahawitthayalai Songkhla Nakharin (PSU Radio Network). English translation is Prince of Songkha University radio station. It is an education radio station operated by Prince of Songkhla University.

There are three videos of PSU Radio Network FM 107.25MHz from Pattani, Thailand received in three locations:

1. Kota Bharu (140km)
2. Pasir Mas (135km)
3. Jeli (145km)

Transmission power is 1kW.

==SINPO code of PSU Radio Network FM 107.25MHz from Pattani, Thailand received in Kelantan, Malaysia==

1. Kota Bharu: 42233 (interference by Fly FM 107.4MHz Peringat)
2. Pasir Mas: 12221
3. Jeli (nearby R&R Titiwangsa): 55455

Kelantan FM has a low power transmitter in Bukit Bintang, Besut, Terengganu on FM 107.1MHz to cover East Kelantan (Bachok), it is not only interfered by SV Sound Radio FM 107.0MHz from Tak Bai, Thailand in Kota Bharu and Tumpat, it is also interfered by PSU Radio Network FM 107.25MHz Pattani Thailand in Kota Bharu too. Although PSU Radio Network FM 107.25MHz from Pattani is receivable in North Kelantan, but it is interfered by local Fly FM 107.4MHz from Peringat which covers these locations.

Apart from PSU Radio Network FM 107.25MHz, there are none of other Pattani radio stations can be received in North Kelantan. Radio Thailand Pattani FM 101.0MHz, MCOT Pattani FM 91.0MHz and TP4 FM 93.5MHz are not receivable there.

988 FM 96.1MHz from Gunung Jerai and Melody FM 98.5MHz Gunung Kledang received at Jeli-Gerik highway

If you follow Senn Lens (Youtuber from Kelantan) Youtube channel, he received 988 FM 96.1MHz from Gunung Jerai at Jeli-Gerik highway.

According to the video, 988 FM 96.1MHz from Gunung Jerai was received at Jeli-Gerik highway before Tasik Banding while driving from Jeli to Gerik. The receiving signal quality was moderate to good, no interference found. As this highway has high elevation above sea level, so the reception is still clear.

==988 FM 96.1MHz Gunung Jerai receiving signal result==
* Frequency: FM 96.1MHz
* Power: 10kW
* Transmitting site: Gunung Jerai, Kedah
* Receiving location: Jeli-Gerik Highway before Tasik Banding, Perak
* Distance: Approximately between 115km-130km
* SINPO code: 44444

I have no information of its exact location, so there is approximate distance.

Next, Melody FM 98.5MHz from Gunung Kledang, Ipoh was received at Jeli-Gerik highway too before Tasik Banding.

   

==Melody FM 98.5MHz receiving signal result==
* Frequency: FM 98.5MHz
* Power: 2kW

* SINPO code: 44444

94PFM We Love Satun from Thailand received in Penang, Malaysia (Teluk Bahang)

On 14th February 2020 (Valentine's Day), a YouTuber named Senn Lens published a radio aircheck video on YouTube by receiving 94PFM We Love Satun in Penang, Malaysia.

  

According to this video, 94PFM We Love Satun on FM 94.0MHz was received nearby Teluk Bahang, Penang, Malaysia.

94PFM We Love Satun transmitter site is located in Tirasathit Alley, Tambon Phiman, Amphoe Mueang Satun, Thailand which is 94PFM We Love Satun studio and office, instead of Khuan Khan site where is MCOT and Radio Thailand Satun site.

The receiving condition is moderate, but signal goes weak when pass through some small hills. He received in the car which is Toyota Corolla Altis E170, although 94PFM We Love Satun has 100kHz frequency separation from local Mutiara FM 93.9MHz Gunung Jerai, but according to the video, 94PFM We Love Satun had no interference from Mutiara FM 93.9MHz Gunung Jerai, I strongly believe that his Toyota Corolla Altis E170 car multimedia system is high sensitivity radio receiver which can filter the interference noise.

The distance from 94PFM We Love Satun site to Teluk Bahang, Penang, Malaysia is about 129km-130km.

==94PFM We Love Satun reception signal result==
* Frequency: FM 94.0MHz
* Power: 0.5kW
* Transmitting site: Tirasathit Alley, Tambon Phiman, Amphoe Mueang Satun, Thailand
* Receiving location: Teluk Bahang, Penang, Malaysia
* Distance: 129km
* SINPO code: 23322

SINPO stands for "Signal Interference Noise Propagation Overall" (1 is poor, 5 is excellent for each section), which is always used by DXers for signal reception result.

This is 4th location in Malaysia to receive 94PFM We Love Satun FM 94.0MHz from Satun, Thailand, that is Teluk Bahang, Penang. Previous locations were:

1. Langkawi, Kedah
2. Alor Setar, Kedah
3. Yan, Kedah (Gunung Jerai top peak)

List of Indonesia AM (MW) radio stations that I received in Malaysia

Here are the Indonesia AM (MW Medium Wave) radio stations list that I received in Malaysia, receiving location is based in Balakong and Puchong, Selangor, all stations are Radio Republik Indonesia (RRI):

* AM 927kHz: RRI Pekanbaru PRO-4
* AM 1251kHz: RRI Banda Aceh PRO-4
* AM 1413kHz: RRI Sungai Liat PRO-1
* AM 1512kHz: RRI Bukittinggi PRO-1 

15 years ago, I was used to receive RRI Tanung Pinang PRO-1 on AM 1341kHz, RRI Palembang PRO-1 AM 1287kHz, RRI PRO-3 AM 999kHz from Jakarta, and RRI Padang PRO-1 AM 1179kHz in Malaysia during early morning and night transmission.

AM 1341kHz, AM 1287kHz and AM 1179kHz are possibly inactive as they might move to FM radio transmission. Radio Republik Indonesia gradually closes down AM radio transmission in Indonesia and slowly shifts to FM radio for the entire country.

In my receiving location, Radio Republik Indonesia RRI Bukittinggi PRO-1 AM 1512kHz was having co-channel interference from Thailand Air Force Radio Station AM 1512kHz from Songkhla, Thailand. I remembered when I listened to Thai songs on AM 1512kHz, I could hear Muslim prayer (Azan) on the frequency while I was in the car.




==AM 927kHz RRI Pekanbaru PRO-4==

== AM 1413kHz RRI Sungai Liat PRO-1 ==




== AM 1512kHz RRI Bukittinggi PRO-1 ==

Radio Thailand Betong FM 93.0MHz received in Malaysia.

Radio Thailand Betong FM 93.0MHz, a district radio station for Betong in Yala province, Thailand, nearby Perak, Malaysia border. It does not only serve Betong listeners, it can be received in Pengkalan Hulu, Gerik and Klian Intan of Perak, Baling of Kedah too.

Previously I had received this radio station in Penang, Ipoh and Kuala Kangsar and another YouTuber named Senn Lens received this radio station in Kota Bharu, Kelantan, and Kulim of Kedah.

Although this radio station listenership within Betong district is small, but the coverage of Radio Thailand Betong FM 93.0MHz is quite wide. The first location that I received this radio station was in Penang, the receiving signal condition was not good and interfered by Hitz FM 92.8MHz Gunung Jerai which is local transmitter site for Penang.

==Kulim, Kedah==

==Penang== (Georgetown and Batu Feringghi)

 

==Perak== (Kuala Kangsar, Ipoh, Taiping, and Gerik)




==Kelantan== (Kota Bharu)

 

PENGUMUMAN: Frekuensi Zayan di Taiping, Perak ialah FM 98.1MHz

Kepada pendengar Zayan yang tidak dapat mencari frekuensi di Taiping, Perak, untuk makluman, Zayan boleh diterima di Taiping, Perak pada FM 98.1MHz dari Gunung Jerai, dimana sama frekuensi dengan Alor Setar dan Pulau Pinang.

Walaupun Taiping terletak di negeri Perak, dan Ipoh adalah ibu bandar negeri Perak, tetapi Taiping tidak akan menerima Zayan pada frekuensi Ipoh FM 106.4MHz kerana isyarat Gunung Kledang terlindung oleh Gunung Bubu yang berada di Terong dan Changkat Jering. Jika kita menerima Zayan di Taiping pada FM 106.4MHz (Ipoh), kesemua isyarat adalah bunyi bersebelahan daripada Melody FM 106.5MHz Gunung Jerai.

Penerimaan siaran radio Zayan masih jelas di Taiping pada FM 98.1MHz dari Gunung Jerai, pendengar Zayan cuma tala kepada FM 98.1MHz sahaja dari Taiping sehingga Kangar.

DISCLAIMER: Blog article regarding my suggestion of FM radio frequencies. Misleading frequency information on Malaysia radio stations' Wikipedia.

Recently there is much of misleading information on selected Malaysia FM radio stations on Wikipedia, especially frequencies list section. I was informed by my friends about that, and hereby I would like thank to my friends for informing me about this matter. I'm Philip Yong, the owner of Philip DXing Log noted this misleading frequency information on Wikipedia seriously.

Bernama Radio Wikipedia

goXUAN Wikipedia

Kool FM Wikipedia

Raaga Wikipedia

Zayan Wikipedia

Above all the screenshots, those Wikipedia edits are badly misleading to the public enough. Let me to make clarifications by radio station. 

Raaga is a Malaysia Tamil radio station by Astro Radio. Due to license condition, currently it is available in West Coast of Peninsular Malaysia only, meanwhile East Coast is dominated by Gegar. Back to 2013, I suggested Astro Radio to expand coverage for Raaga in Kuantan only, but I was informed that Astro Radio would not make such suggestion due to license restrictions and market condition. 

About the misleading frequencies information on Raaga, Bernama Radio, goXUAN, CityPlus FM and Zayan's Wikipedia, most of the frequencies can cause heavy interference to existing radio stations. I believe such Wikipedia editor who did these all never performed frequencies studies and took into other considerations.

In terms of technical aspects, I strongly the particular user who edited these Wikipedia article never takes frequency planning study, interference study, border coordination study and marketing into considerations.

==Bernama Radio==

* 88.6MHz Kedah, Perlis, Penang: Cause interference to Traxx FM Bukit Genting 88.5MHz, Kedah FM Bukit Sungai Kecil 88.5MHz, and Radio Klasik FM 88.7MHz Bukit Palong

* 105.7MHz Ipoh: Depends on which transmission site located at, but if it is located in Gunung Kledang, it would cause interference to Lite FM 105.7MHz Gunung Ulu Kali

* 103.5MHz Taiping: Bad interference to Radio Klasik FM 103.3MHz Bukit Larut which covers Taiping

* 89.1MHz Kuantan: Interference to Radio Klasik FM 89.2MHz Bukit Sulai in Pekan, Gambang

* 106.4MHz Kuala Terengganu: OK

* 95.7MHz Kota Bharu: Interference to Radio KIasik FM 95.5MHz Bukit Bakar

* 93.5MHz Seremban: Interference to 988 FM 93.3MHz Gunung Telapak Burok and Radio Klasik FM 93.6MHz Gunung Ledang

* 88.9MHz Melaka/North Johor: Interference to BBC World Service Singapore and Traxx FM 88.7MHz Gunung Telapak Burok because Traxx FM 88.7 has separation from Suria FM 88.5MHz Gunung Ledang

==goXUAN==

*107.6 MHz Kedah, Perlis, Penang: Current goXUAN FM 107.6MHz is from Bukit Penara for Penang, South Kedah, and North perak only. Not include Alor Setar and Perlis. It would cause interference to Kool FM Alor Setar 107.3MHz, Minnal FM 107.5MHz Bukit Dedap coverage badly.

* 97.0MHz Ipoh and Taiping?: Interference to Sinar FM 96.9MHz Gunung Kledang. On Malay Wikipedia, 97.3MHz Ipoh can cause interference to Perak FM 97.3MHz Changkat Rembian

* 95.5MHz Kuantan: Interference to Pahang FM 95.5MHz Bukit Sulai in Pekan, Gambang

* 103.6MHz Kuala Terengganu: OK

* 101.3MHz Kota Bharu: Interference to Radio KIasik FM 101.1MHz Wakaf Che Yeh and Golok FM 101.5MHz

* 93.5MHz Melaka/North Johor: Interference to Radio Klasik FM 93.6MHz Gunung Ledang

* 88.5MHz Kota Kinabalu: Not OK, due to interference to Labuan 88.5MHz

* 100.5MHz Kuching: Sounds ok.

goXUAN is only available in Klang Valley on FM 88.9MHz and Penang on FM 107.6MHz. No other locations are expanded due to its license conditions.

==RAAGA==

* 105.7MHz Kuantan: OK

* 95.2MHz Kuala Terengganu: Interference to Minnal FM 95.3MHz Bukit Bintang in Setiu and Besut

* 103.7MHz Kota Bharu: Interference to Narathiwat FM 103.75MHz

Raaga has no plan to expand coverage to east coast as the region is not its market.

==ZAYAN==

Same condition as goXUAN. Other than current 6 frequencies (104.9/106.4/98.1/91.6/98.9/92.8) which carried formerly by Red FM, Zayan never plans to expand to other locations due to license conditions.

Its existing frequency FM 106.4MHz Ipoh and Taiping is misleading, FM 106.4MHz is for Ipoh only, excluding Taiping. In Taiping, it is very difficult to receive Ipoh FM radio stations due to big mountains of Gunung Bubu nearby Terong. To listen to Zayan in Taiping, its frequency is FM 98.1MHz from Gunung Jerai, not FM 106.4MHz Gunung Kledang!

* 103.1MHz Kuala Terengganu: Interference with Era FM 102.8MHz Bukit Besar.

* 100.9MHz Kota Bharu: Interference to Radio KIasik FM 101.1MHz Wakaf Che Yeh and Minnal FM Bukit Bakar FM 100.9MHz

==CityPlus FM==

The Malaysia first Chinese business radio station is only available in Seremban (106.0MHz) and Kuching (92.5MHz), but it is available in Central Pahang, part of Selangor/Kuala Lumpur/Melaka/Johor on FM 106.0MHz transmitted from Gunung Telapak Burok.

* 106.0MHz Kedah and Perlis: Interference to Ai FM 106.1MHz Bukit Larut, Traxx FM 105.9MHz Bukit Dedap (Sik, Kedah)/UUM Sintok and VR Radio FM 106.0MHz (Danok, Thailand)
* 106.0MHz Kuala Terengganu: Interference to Lite FM 105.9MHz Bukit Besar
* 106.0MHz Johor Bahru: Interference to IKIM FM 106.2MHz Gunung Pulai
* 103.0MHz Penang: Interference to Perlis FM 102.9MHz Padang Pauh and IKIM FM 102.7MHz Bukit Genting
* 103.0MHz Ipoh: Interference to IKIM FM 102.7MHz Gunung Kledang and Melody FM 103.0MHz Gunung Ulu Kali
* 103.0MHz Kuantan: Interference to Minnal FM 103.3MHz Bukit Pelindung
* 103.0MHz Kota Bharu: Interference to Kelantan FM 102.9MHz Wakaf Che Yeh

CityPlus FM never plans to expand its coverage in these such areas above due to market condition.

==KOOL FM==

102.1MHz Seremban, 100.9MHz Melaka/North Johor, 94.9MHz Ipoh, and 105.7MHz Taiping. My information on previous blog article in 2015/16 was taken and copied on Wikipedia without my knowledge, those information on my blog article is not official and just a personal suggestion (in general way), somehow the frequency is expired.

* 102.1MHz Seremban: No longer suitable because interference with Pahang FM 102.2MHz Bukit Fraser (spotted since October 2018)
* 94.9MHz Ipoh: Not suitable because interference to Radio Klasik Gunung Jerai FM 94.9MHz coverage in Kedah 
* 87.5MHz Johor Bahru: Not suitable because of Batam FM 87.6MHz, but depends on which site that broadcaster uses.
* 104.0MHz Langkawi: None of radio stations from Media Prima enters to Langkawi market due to no commercial value condition. In addition, FM 104.0MHz will cause interference to Border Patrol Police radio station FM 104.0MHz in Songkhla province.

When I read these Wikipedia article, to avoid public from misunderstanding about it, I removed these misleading articles immediately. In addition, no such official announcements are made by radio stations. Wikipedia is not a platform to make fake news, fake articles, misleading information or mimic somebody. 

Next, come to Kool FM. Currently it has 6 frequencies in service, 101.3MHz Kuala Lumpur, 90.2MHz Penang, 93.6MHz Kuala Terengganu, 88.6MHz Kota Bharu, 107.3MHz Alor Setar, and 104.3MHz Kuching. No any further frequencies announcements are made by Kool FM. Yes, I found that someone was using my information to write on Kool FM Wikipedia frequency section with a remark "COMING SOON", but I removed them immediately because those information are false.

* 102.1MHz: Seremban
* 100.9MHz: Melaka/North Johor
* 94.9MHz: Ipoh and Central Perak
* 105.7MHz: Taiping and North Perak

For everyone's attention, the frequencies above such as 102.1MHz, 100.9MHz, 94.9MHz and 105.7MHz were used to be published on my blog in late 2015 till 2018 regarding my opinion and suggestion for Kool FM personally. 

The frequencies above were totally unofficial, they were just my personal proposal and opinion, I did not get any information from somebody within the broadcaster company. Those frequencies that were listed, based on basic frequency scanning in my location by using radio receiver, but other considerations were not fully included yet such as interference and transmission parameters. 

In this article, I include RF analysis to answer the user who publish fraud information on Zayan, goXUAN, Bernama Radio, CityPlus FM Wikipedia.

I work within broadcast industry (selling broadcast equipment). Frequency study and interference analysis are mandatory processes when propose frequency parameter in an area. It is not easy to do such thing, as it takes many considerations. For the frequencies assignment, the final decision is done by MCMC, not broadcasters.

As the blog articles on Philip DXing Log regarding unofficial frequency suggestions opinion, I will not tolerate to people who misuse my articles on official platform such as Wikipedia, I remove them from Wikipedia in order to public interest. 

I respect people's decision to publish their thoughts on social media platform such as Facebook, Twitter, YouTube, Blogger and Instagram, but not on Wikipedia. 

Wikipedia is not a platform to put misleading content, and mimic somebody.

If someone would like to use and share my article, I would definitely welcome them, but never use my article on Wikipedia without permission.

I fully respect everyone's thoughts and opinions as I emphasized on freedom of speech, but I never allow to use unofficial information on official platform. Sharing opinion each other is not stupid and wrong, but it is depended on right situation, right place and right time to do so.

Q&A: FM 92.4MHz in Ipoh, Perak from Gunung Kledang. Suitable or non-compliance?

2.5 years ago, my blog Philip DXing Log received a comment from Syafiq on "Kool FM Perak frequency (PART 1 suggestion)".

First of all, thanks for everyone's feedback on my blog post. Can FM 92.4MHz be used in Gunung Kledang Ipoh?

This was an interesting question, but the answer is NO! I will share about the reasons.

The reason why isn't FM 92.4MHz suitable to be used for Ipoh radio transmission from Gunung Kledang is there are already having two radio stations which transmitted from Gunung Kledang and their frequencies allocations are nearby FM 92.4MHz, namely Ai FM 92.1MHz Gunung Kledang and Hitz FM 92.7MHz Gunung Kledang.

If a radio station assigns its Ipoh frequency on FM 92.4MHz, it will definitely interfered to Ai FM 92.1MHz and Hitz FM 92.7MHz, or FM 92.4MHz is badly interfered by Ai FM 92.1MHz and Hitz FM 92.7MHz. Just like a burger is centered by two breads, when you eat a hamburger, two breads will "press" the burger because it located between two breads. 

The maximum frequency deviation of a radio station is 75kHz +/-. For this study, even if install with band pass filter (4 or more poles), this does not guarantee FM 92.4MHz avoids interference each other.

92.1MHz: Ai FM Gunung Kledang

92.4MHz: Gunung Kledang

92.7MHz: Hitz FM Gunung Kledang

<300kHz, NOT GOOD>

Technically, the minimum frequency separation for radio station within same sites and coverage is 400kHz. It is impossible to have a band pass filter to be installed for these 3 stations in Gunung Kledang.

Another different case is One FM 87.6MHz and Fly FM 87.9MHz, both are from Gunung Kledang, and having 300kHz separation. For this case, it is still ok because "no sandwich" allocation within same sites. In addition, both of them are using high pass filter.

In addition, FM 92.4MHz is not suitable to be used in Gunung Kledang due to interference with Nasional FM 92.3MHz Bukit Ladang Teh, minimum separation must be at least 200kHz. 

If FM 92.4MHz is used in Perak's gap filler transmission site such as FELDA Terolak, or Ulu Slim (like Perak FM), it is ok because those gap filler areas are not Gunung Kledang coverage. Currently, FM 93.3MHz is the only available frequency in Gunung Kledang, Ipoh, Perak.

MCMC is performing FM frequency re-planning study, and all broadcasters frequency applications are suspended until frequency re-planning study is done. Therefore, frequency proposal is not suitable to be done at the moment.

RTM radio stations in Langkawi, Kedah

RTM has two FM radio stations in Langkawi, transmitted from Gunung Raya, they're Langkawi FM 104.8MHz and Kedah FM 105.7MHz, excluding Langkawi FM RTM Kuah 87.5MHz which is low power repeater for Kuah (target underwater).

For other RTM radio stations such as Radio Klasik, Nasional FM, Traxx FM, Ai FM and Minnal FM in Langkawi, they have no Gunung Raya repeater. These radio stations can be tuned only from Gunung Jerai, but available only in few locations within Langkawi Island such as Kuah.

Radio Klasik FM 94.9MHz, Nasional FM 100.5MHz, Traxx FM 98.7MHz, Ai FM 101.3MHz and Minnal FM 96.7MHz. 

In certain Langkawi locations, these radio stations could be clashed by Thailand radio stations, especially Radio Klasik FM 94.9MHz which is interfered by Radio Thailand Yala FM 95.0MHz, but alternatively Radio Klasik can be tuned via FM 88.7MHz from Bukit Palong (Baling, Kedah) which is much further than Gunung Jerai.

When RTM national radio stations cannot be received in Langkawi, they can be received via MYTV on digital terrestrial television platform, but for radio, only two stations Radio Klasik and Nasional FM maybe tuned alternatively from Bukit Palong on 88.7MHz and 89.7MHz respectively.

It is impossible to tune to RTM Ai FM 92.5MHz, Traxx FM 91.7MHz and Minnal FM 93.3MHz there because the frequencies are overlapped by Hitz FM 92.4MHz Gunung Raya, Thailand Police Radio Station from Tha Phae FM 91.75MHz and MCOT Satun FM 93.25MHz.

As Nasional FM is the RTM flagship radio station, Langkawi FM 104.8MHz can relay Nasional FM during its non-broadcasting hours, rather than duplicate relay from Kedah FM as Kedah FM has 105.7MHz.

If Radio Klasik FM 94.9MHz and Nasional FM 100.5MHz from Gunung Jerai are not receivable in Langkawi, you may try these below:

1. Radio Klasik FM 88.7MHz
2. Nasional FM 89.7MHz

At the moment, it is impossible to launch RTM five national radio stations by having repeater in Gunung Raya because unavailable spectrum and the listeners. Langkawi has more Malay residents, compare with Chinese and Indians. In addition, Langkawi frequency planning need to do more Thailand frequency studies as it is located nearby Thailand border.
