Radio Thailand Yala FM 95.0MHz received in Lojing, Kelantan, Malaysia

Lojing is a highland location in Gua Musang district, Kelantan, located between Cameron Highlands and Gua Musang.

Regarding the radio coverage, Lojing is a remote location actually. When you drive from Cameron Highlands to Gua Musang, the radio stations that you listen regardless tuning frequency from Bukit Larut, Gunung Kledang or Gunung Brinchang will go faded 5-6km after Perak-Pahang-Kelantan border.

As I predict, some of Gunung Kledang (Ipoh) and Bukit Larut (Taiping) radio stations are still receivable after Perak-Pahang-Kelantan border when enter Kelantan state.

In Lojing, RTM radio stations can be tuned via Bukit Bakar. Example: Kelantan FM 97.3MHz in Lojing.

While there are a lot of Malaysia radio stations (except RTM) are not receivable in Lojing, Kelantan, however surprisingly Thailand FM radio stations are receivable there.

Here are some videos of receiving Radio Thailand Yala FM 95.0MHz in Lojing, Kelantan, Malaysia.



Based on the videos, the receiving signal condition of Radio Thailand Yala FM 95.0MHz was quite clear in Lojing Highlands, Kelantan, Malaysia. This radio station broadcasts in Pattani Malay language where the language is widely spoken in Yala, Pattani and Narathiwat provinces of Thailand by Thailand Malay people.

Traxx FM frequency in Gua Musang is FM 94.9MHz from Bukit Chupak, I believe it is not receivable in Lojing. By listening to the signal audio, FM 94.9MHz is locked by Radio Thailand Yala FM 95.0MHz completely there. So, I believe FM 92.0MHz is also Radio Thailand Yala there, rather than RTM Kelantan FM 92.0MHz.

==Reception details of Radio Thailand Yala in Lojing==
- Frequency: FM 95.0MHz
- Power: 1kW
- ERP: 4kW
- Transmission site: Khao Pok Yo, Bannang Sata district, Yala province, Thailand
- Receiving site: Lojing, Kelantan state, Malaysia
- Distance: 180km

Apart from Radio Thailand Yala FM 95.0MHz, Lojing could receive Radio Thailand Yala FM 92.0MHz/94.25MHz, MCOT Yala FM 95.0MHz and Parliament Radio FM 89.0MHz as they're also transmitted from Khao Pok Yo. In addition, I may believe that Radio Thailand Betong FM 93.0MHz, Kor Sor Wor 6 FM 92.5MHz Sungai Padi, Radio Thailand Sungai Golok FM 106.5MHz, Radio Thailand Narathiwat FM 98.25MHz, MCOT Narathiwat FM 96.0MHz, Sathani Witthayu Krachaisiang Tamruat Phuthon Phak 9 {สถานีวิทยุกระจายเสียงตำรวจภูธรภาค 9}  FM 88.25MHz, Sathani Witthayu 912 FM 99.1MHz and Voice of Navy FM 94.75MHz can be received in Lojing, but I doubt about their receiving signal condition there.

RTM has radio stations in Gua Musang from Bukit Chupak such as:

1. Radio Klasik FM 89.7MHz
2. Nasional FM 91.1MHz
3. Kelantan FM 92.0MHz
4. Traxx FM 94.9MHz
5. Ai FM 94.1MHz
6. Minnal FM 93.2MHz

These radio stations are only covering Gua Musang town, and they're not for Lojing too. Bukit Chupak is a small hill in Gua Musang town.

In terms of frequency analysis condition, Kelantan FM 92.0MHz, Ai FM 94.1MHz and Traxx FM 94.9MHz from Bukit Chupak will be interfered by Radio Thailand Yala FM 92.0MHz, FM 94.25MHz and FM 95.0MHz respectively from Khao Pok Yo in Lojing, Kelantan. Meanwhile Radio Klasik FM 89.1MHz and Nasional FM 93.1MHz from Gunung Brinchang are not receivable in Lojing at all, and they're interfered by Parliament Radio FM 89.0MHz Yala and Radio Thailand Betong FM 93.0MHz there. Besides that, some of Ipoh based radio stations from Gunung Kledang such as Radio Klasik FM 88.3MHz, Ai FM 92.1MHz, Mix FM 94.3MHz, and Zayan FM 106.4MHz may be interfered by Thailand radio stations such as Narathiwat FM 88.25MHz, Radio Thailand Yala FM 92.0MHz/94.25MHz and Radio Thailand Sungai Golok FM 106.5MHz in Lojing.

For Malaysia radio stations, here are the frequencies that you can try when you're in Lojing, Kelantan.

Kit Kaan Witthayu Krajaisiang Yala FM 100.0MHz received in Kota Bharu, Kelantan, Malaysia



In Kota Bharu, Kelantan, Malaysia, there are a lot of Thailand radio stations are transmitted from Yala province, the receiving signals are quite clear there. Usually receivable Yala radio stations in Kota Bharu are:

1. Satthanii Witthayu Ratthasapha (Parliament Radio) FM 89.0MHz
2. Radio Thailand Yala FM 92.0MHz, FM 94.25MHz and FM 95.0MHz
3. MCOT Yala FM 102.5MHz
4. Radio Thailand Betong FM 93.0MHz

Except Radio Thailand Betong FM 93.0MHz, the Yala radio stations listed above are transmitted from Khao Pok Yo, Bannang Sata district, Yala, Thailand. For your information, Khao Pok Yo is Thailand version of Gunung Ulu Kali because the hill is located at the border between Yala and Narathiwat, the height of the hill is around 750m.

In this video, FM 100.0MHz is Kit Kaan Witthayu Krajaisiang from Yala province, but different transmissions site. The reception of FM 100.0MHz in Kota Bharu, Kelantan, Malaysia is not clear as Radio Thailand Yala FM 95.0MHz because Kit Kaan Witthayu Krajaisiang Yala FM 100.0MHz is transmitted from Khao Buyo, Bannang Sareng in Mueang Yala District, Yala, Thailand.

==Reception details of Kit Kaan Witthayu Krajaisiang Yala FM 100MHz in Kelantan, Malaysia==
- Frequency: FM 100.0MHz
- Power: 1kW
- Transmission site: Khao Buyo, Bannang Sareng, Mueang Yala district, Yala Province, Thailand
- Receiving site: Wakaf Bharu, Kota Bharu, Kelantan, Malaysia
- Distance: 109km

The height of Khao Buyo is lower than Khao Pok Yo.

This radio station was also used to air Allahyarham Tok Guru Nik Aziz (former Kelantan Menteri Besar) ceramah (speech) many years ago.

99.8MHz: Melody FM Bukit Panau
100.0MHz: Kit Kaan Witthayu Krajaisiang (Khao Buyo, Yala)

As FM 100.0MHz Yala has 200kHz frequency separation from Melody FM 99.8MHz Bukit Panau, so I assume that Kit Kaan Witthayu Krajaisiang Yala FM 100.0MHz will have adjacent channel interference from Melody FM 99.8MHz in Kota Bharu and North Kelantan, Malaysia, unless transmitted from Khao Pok Yo.

However, if FM 100.0MHz is transmitted from Khao Pok Yo, it will cause co-channel interference to RTM Ai FM 100.0MHz coverage in Gerik, Perak. For the frequency separation, Thailand NBTC and Malaysia MCMC had already agreed the minimum frequency separation between Gerik and Yala (based on Khao Pok Yo) must be 200kHz.

The frequency separation between Malaysia bordering sites and Yala does not include Khao Buyo and Tambon Sateng as they are lower height transmission sites.



MCOT Pattani FM 91.0MHz is receivable along Gerik-Jeli highway, but co-channel interference from Mix FM 91.0MHz Gunung Jerai



In this video, YouTuber Senn Lens received FM 91.0MHz along Gerik-Jeli highway when he was going from Kota Bharu to Penang.

FM 91.0MHz actually was MCOT Radio Pattani from Pattani province, Thailand there, but it had co-channel interference from Mix FM 91.0MHz Gunung Jerai when came to Perak-Kelantan border after R&R Titiwangsa.

==Reception details of MCOT Pattani in Gerik-Jeli highway==
- Frequency: FM 91.0MHz
- Power: 1kW
- Transmission site: Rusamilae, Mueang Pattani district, Pattani province, Thailand
- Receiving site: Gerik-Jeli highway (nearby R&R Titiwangsa), Malaysia
- Distance: 149km

==Reception details of Mix FM in Gerik-Jeli highway==
- Frequency: FM 91.0MHz
- Power: 2kW
- Transmission site: Gunung Jerai, Kedah, Malaysia
- Receiving site: Gerik-Jeli highway (nearby R&R Titiwangsa), Malaysia
- Distance: 125km

It is interesting to detect co-channel interference between MCOT Pattani and Mix (Gunung Jerai) on FM 91.0MHz in this location. Gerik-Jeli highway is a hill and curvy road, actually the locations between Gerik and Jeli are difficult to receive Malaysia FM radio stations due to terrain, however Thailand radio stations from Betong, Yala, and Sungai Golok can be received easily, somewhat Pattani too.

Co-channel interference between MCOT Pattani and Mix on FM 91.0MHz between Gerik and Jeli is considered ok, and no listeners impact because the locations are not under their broadcast coverage.

The video of receiving FM 91.0MHz with interference is quite interesting and impressive actually. If a Mix FM listeners tune the station there, but interference, I may suggest the listeners to try tuning some alternative frequencies below in order to continue listening to Mix while driving from Jeli to Gerik along the highway.

1. FM 91.3MHz Bukit Larut
2. FM 94.3MHz Gunung Kledang

However, the alternative frequencies of Mix FM listed above does not guarantee whether they're receivable along Gerik-Jeli highway or not due to terrains. I doubt about the receiving signal condition of FM 91.3MHz and FM 94.3MHz there, meanwhile I may predict that Mix FM 94.3MHz from Gunung Kledang may be clashed by Radio Thailand Yala FM 94.25MHz from Khao Pokyo, Bannang Sata district, Yala, Thailand. Therefore, the highest possible frequency to tune to Mix in Gerik-Jeli highway is FM 91.3MHz from Bukit Larut.

In terms of geographical condition, Bukit Larut has higher elevation than Gunung Kledang. I remembered that I was told by MCMC that Bukit Larut transmission somewhat could overspill to Bukit Bakar, Kelantan coverage when come to co-channel frequency when I attempted to propose FM 105.7MHz for IKIM FM Bukit Larut transmission to cover Taiping.

TP4 FM 93.5MHz Pattani, Thailand received in Kota Bharu, Kelantan, Malaysia

After PSU Radio FM 107.25MHz as only Pattani radio station which is received in Kota Bharu, Kelantan, the YouTuber Senn Lens had received another Pattani FM radio station, known as TP4 FM 93.5MHz.

TP4 FM is known as Satthanii Witthayu Krajaising Kong Thap Phak Thi Sii (4th Army Area), also called as Thor Por Sii for Thai radio call sign. This radio station is available in Pattani province on FM 93.5MHz.

TP4 FM 93.5MHz Pattani station is transmitted from Yarang district, border with Yala province. This results Pattani and North Yala (Amphoe Mueang Yala, Raman, Yaha and Krong Pinang) can receive TP4 FM 93.5MHz from Yarang, Pattani. As TP4 FM has no Yala provincial radio station like Songkhla, Trang, Surat Thani, Pattani, Chumphon, Phatthalung and Nakhon Si Thammarat, but it is available in part of Yala province too.


Back to its reception in Kota Bharu, Kelantan, Malaysia, the signal is weak actually on FM 93.5MHz as it is transmitted from Yarang, which is low elevation height. Here is the reception details of TP4 FM 93.5MHz in Kota Bharu, Malaysia.

==TP4 FM 93.5MHz reception details==
- Frequency: FM 93.5MHz
- Power: 1kW
- Transmitter site: Yarang, Pattani, Thailand
- Receiver site: Wakaf Bharu, Kota Bharu, Kelantan, Malaysia
- Distance: 111km
- Receiving date: 7th May 2020 1900H (UTC+8)

In Kota Bharu, TP4 FM 93.5MHz Pattani is difficult to be received, and signal is not clear and consists with static.

Bangkok Meteorological Radio 6765kHz and 8744kHz received in Malaysia (Balakong, Selangor state)

On today evening, I received two frequencies of Bangkok Meteorological Radio in Balakong, Selangor, Malaysia on shortwave band, they're 8744kHz and 6765kHz.

Here are the videos:




Accordring to these two videos, both have strong signal, but unstable reception. As I'm using TECSUN PL-380 which has no SSB (single side band), so it is not clear to hear the audio of weather annoucement on SW 8744kHz and 6765kHz.

==Information of Bangkok Meteorological Radio received in Malaysia==
* Frequency: SW 8744kHz and 6765kHz
* Transmission site: Thai Meteorological Department, Bangkok, Thailand
* Receiver site: Balakong, Selangor, Malaysia (20km from Kuala Lumpur)
* Distance: 1192km
* Receiving date/time: 21.05.2020 2010H (UTC+8)
* Radio receiver: TECSUN PL-380 with built-in whip antenna

[Thailand RF analysis] FM 102.75MHz Songkhla (PART 2): Khao Kho Hong at 50W power



Hat Yai is considered as Southern Thailand version of Bangkok in terms of FM radio stations frequency spectrum traffic condition because the frequency spectrum is quite peak in Hat Yai due to growing of community and commercial radio stations, alongside public broadcasters such as Radio Thailand, MCOT, Parliament Channel, Royal Thai Army, Air Force, Navy and Prince of Songkhla University.

However, I already noticed that Sunshine Radio Hat Yai was ceased since 2016, alongside recent defunct Sunshine Radio station in Phuket. In addition, according to Asiawaves.net, FM 102.75MHz was previously carried by Workers' Radio in Hat Yai, but it is INACTIVE.

In facts, FM 102.75MHz is now a vacant frequency in Hat Yai, Thailand, meanwhile Your FM 102.5MHz also broadcasts in Hat Yai as low power narrowcast community radio station. By referring Bangkok FM radio frequency spectrum condition, the main transmitter site radio stations separated at 500kHz, meanwhile the frequency separation between main radio stations and narrowcast radio stations is 250kHz.

Example: FM 92.5MHz, FM 92.75MHz and FM 93.0MHz

FM 92.5MHz is Radio Thailand national network, then FM 93.0MHz is Cool Fahrenheit 93 (under Voice of Navy), so separation is 500kHz. Between FM 92.5MHz and FM 93.0MHz, the frequency FM 92.75MHz is used as narrowcast broadcast stations such as: Sathani Witthayu Khon Charoen Nakhon {สถานีวิทยุคนเจริญนคร}, Sathani Witthayu Medee (Global Medee) {สถานีวิทยุมีดี (โกลบอลมีดี)}, and Sathani Witthayu Krachaisiang Phuea Phraputthasasana Haeng Chat lae Sangkhom {สถานีวิทยุกระจายเสียงพระพุทธศาสนาแห่งชาติและสังคม}, these 3 radio stations on FM 92.75MHz operate at very low power transmission, so they're considered as narrowcast.

For Hat Yai site, FM 102.75MHz is not a problem to be used in Khao Kho Hong as it has 500kHz frequency separation from Radio Thailand Songkhla FM 102.25MHz which is transmitted in same location, meanwhile Your FM 102.5MHz is transmitted from Tambon Hat Yai as low power community radio station to cover the sub-district only.

While FM 102.75MHz is suitable to be used in Khao Kho Hong, but to prevent interference to Your FM 102.5MHz, it is recommended to use low power transmitter there as much 50W. In addition, interference to border region (Malaysia) must be considered. Hence, I will issue RF analysis and tentative parameter of FM 102.75MHz for Khao Kho Hong transmission to cover Hat Yai.

In Khao Kho Hong, there are about 3 tower locations.

1. MCOT Songkhla FM 96.5MHz tower (low peak)
2. Air Force & Radio Thailand Songkhla transmission tower (upper peak)
3. Hat Yai Municipal Park side top peak

==Tentative parameter of FM 102.75MHz Hat Yai==
* Frequency: FM 102.75MHz
* Power: 50W
* Example antenna model: SIRA FM-04 3 bay array dipole antenna
* Antenna type: Dipole antenna
* Antenna polarization: Vertical
* Antenna gain: 6.0dBd
* ERP: 200W

==RF analysis==

102.5MHz: Your FM Hat Yai
102.75MHz: Khao Kho Hong, Hat Yai (50W)
<250kHz, OK>

102.7MHz: Nasional FM UUM Sintok
102.75MHz: Khao Kho Hong, Hat Yai (50W)
<50kHz, OK>

102.75MHz: Khao Kho Hong, Hat Yai (50W)
102.9MHz: Perlis FM Padang Pauh
<150kHz, OK>

102.25MHz: Radio Thailand Songkhla
102.75MHz: Khao Kho Hong, Hat Yai (50W)
<250kHz, OK>

102.75MHz: Khao Kho Hong, Hat Yai (50W)
103.25MHz: Satthani WItthayu Ratthasapha (Parliament Radio)
<500kHz, OK>

102.75MHz: Khao Kho Hong, Hat Yai (50W)
103.0MHz: Khluen Muanchon Khon Thepha {คลื่นมวลชนคนเทพา}
<250kHz, OK>

Next, I will show the coverage report of Khao Kho Hong at 50W power with 3 bay array dipole antenna in 3 different tower locations.

1. Khao Kho Hong (lower peak)


2. Khao Kho Hong (Upper Peak)



3. Khao Kho Hong (Hat Yai Municipal Park side)




According to the coverage, Khao Kho Hong upper peak and Hat Yai Municipal Park top peak have same coverage, but Khao Kho Hong lower peak (MCOT tower) has lesser coverage population. For border area transmission, lower peak Khao Kho Hong has coverage in Padang Besar, Perlis which is closer to Perlis FM 102.9MHz.

Besides that, the transmission of FM 102.75MHz from Khao Kho Hong will not interfere RTM Nasional FM 102.7MHz in Sintok and Bukit Kayu Hitam because it transmits at low power as much 50W. In Bukit Kayu Hitam, Nasional FM is still receivable and clear on 100.5MHz from Gunung Jerai.

Although FM 102.75MHz Khao Kho Hong has just only 50kHz frequency separation from RTM Nasional FM 102.7MHz UUM Sintok, but there is no interference impact within broadcast area, however Nasional FM 102.7MHz and Khao Kho Hong FM 102.75MHz have minor interference in Sadao, Thailand.

For my recommendation, as FM 102.75MHz covers Hat Yai only, so I suggest that FM 102.75MHz to be used at Hat Yai municipal park of Khao Kho Hong hill, rather than Upper peak (Radio Thailand tower) and lower peak (MCOT tower).



==Complete tentative RF proposal of FM 102.75MHz for Hat Yai transmission (for non-professional use only)==
- Frequency: FM 102.75MHz
- Power: 50W
- Transmission site: Khao Kho Hong (Hat Yai municipal park side), Hat Yai city, Songkhla province, Thailand
- Sample transmitter model: Elettronika MIZAR2 50
- Sample antenna model: SIRA FM-04 3 bay array dipole antenna
- Antenna polarization: Vertical
- Number of bay: 3
- Sample antenna height: 40m
- Height above sea level: 338m
- Antenna gain: 6.0dBd
- ERP: 200W
- Target location: Hat Yai, Thailand

RF analysis and vacant FM frequencies for Alor Setar, Kedah, Malaysia

Previously I listed FM 91.5MHz, FM 91.9MHz and FM 94.3MHz as vacant frequency for Alor Setar, Kedah as FM radio transmission.

In Alor Setar, FM 91.9MHz and FM 94.3MHz are not suitable to be used in Alor Setar Tower because interference from Radio Thailand Yala FM 92MHz and 94.25MHz. For your information, Radio Thailand Yala FM 92.0MHz is high power transmitted radio station.

In fact, Radio Thailand Yala FM 92.0MHz and FM 94.25MHz are quite clear and stable in Alor Setar, Kedah, Malaysia. However, there are another two vacant FM frequencies which can be used for Alor Setar radio transmission, such as FM 91.5MHz and FM 93.7MHz.

Let's study basic RF analysis by involving existing stations.

1. FM 91.5MHz

91.3MHz: Mix FM Bukit Larut
91.5MHz: Alor Setar Tower
<200kHz, OK>

91.5MHz: Alor Setar Tower
91.7MHz: Traxx FM Bukit Palong
<200kHz, OK>

2. FM 93.7MHz

93.5MHz: Ban Mai FM Hatyai
93.7MHz: Alor Setar Tower
<200kHz, OK>

93.6MHz: Hitz FM Bukit Larut
93.7MHz: Alor Setar Tower
<100kHz, OK>

93.7MHz: Alor Setar Tower
93.9MHz: Mutiara FM Gunung Jerai (Penang only)
<200kHz, OK>

93.7MHz: Alor Setar Tower
93.75MHz: Life FM La-Ngu, Satun
<50kHz, OK>

For Alor Setar transmission on FM 91.5MHz and 93.7MHz, it is enough to use less than 500W power transmitter, meanwhile as FM 93.7MHz is closer to Mutiara FM 93.9MHz Gunung Jerai (Penang only), so the transmission power of FM 93.7MHz in Alor Setar Tower must not be more than 250W to avoid unnecessary interference.



In conclusion, as May 2020 update, FM 91.5MHz and FM 93.7MHz are the only vacant frequencies for Alor Setar Tower radio transmission. (Presumed)

(FIRST EXCLUSIVE): Radio Republik Indonesia RRI PRO-1 Bengkalis FM 90.6MHz received in Balakong, Selangor, Malaysia


After Tampin, Negeri Sembilan was the first ever Malaysia location that I received RRI PRO-1 Bengkalis FM 90.6MHz, surprisingly I receive this radio station again at my home in Balakong, Selangor (20km from Kuala Lumpur) today.

Actually I have no plan to do a far FM DXing today, instead just perform radio aircheck of UPM Putra FM 90.7MHz at home on my TECSUN PL-380 radio receiver, but UPM Putra FM 90.7MHz is off-air.

When UPM Putra FM 90.7MHz is off-air, I receive an adjacent noise of unknown radio station which likely speaking Malay language. Therefore, I suspect the radio station is from RRI PRO-1 Bengkalis FM 90.6MHz because there is no any radio station within my location uses FM 90.7MHz other than UPM Putra FM. I slowly tune the frequency to FM 90.68MHz and below, then match with RRI PRO-1 Bengkalis FM 90.6MHz online streaming content through mobile phone, it is positively verified.

During the video recording, Radio Republik Indonesia RRI PRO-1 Bengkalis FM 90.6MHz is going to air Muslim afternoon prayer (Azan Zohor) around 1305 hours (UTC+8; Malaysia/China/Singapore/Taiwan/Hong Kong time).


 
 
In this video, I receive Radio Republik Indonesia RRI PRO-1 Bengkalis FM 90.6MHz via Tecsun PL-380 receiver, while antenna is pointing towards southwest direction from my position. To receive this radio station, I must stay in stationary and correct position, otherwise FM 90.6MHz will be fully overlapped by RTM Minnal FM 90.5MHz from Gunung Telapak Burok, Negeri Sembilan.

In Balakong, in fact Minnal FM 90.5MHz from Gunung Telapak Burok is very clear, so RRI PRO-1 Bengkalis FM 90.6MHz has adjacent channel interference noise from Minnal FM 90.5MHz.

The interference from Minnal FM 90.5MHz on RRI PRO-1 Bengkalis FM 90.6MHz which I receive in Balakong, Selangor, Malaysia can be reduced by adjusting the receiver frequency to FM 90.65MHz, FM 90.68MHz on TECSUN PL-380.

It is not receivable most of the time when UPM Putra FM 90.7MHz returns transmission. Due to Covid-19 pandemic, the campus and education sectors are closed, therefore UPM Putra FM 90.7MHz is temporarily off-air. For your information, UPM Putra FM 90.7MHz is a campus radio station by UPM, under RTM broadcast license, it is also known as "RTM Selangor FM Saluran UPM", it only broadcasts on weekdays from 10am till 8pm, it is in silent mode or off-air during non-broadcasting hours.

RRI PRO-1 Bengkalis FM 90.6MHz is likely receivable in coastal areas of Melaka and Johor.

==Reception details of RRI PRO-1 Bengkalis==
* Frequency: FM 90.6MHz
* Power: 5kW (upgraded since 2016)
* Transmission location: Bengkalis, Riau Province, Indonesia

In addition, RTM Perlis FM 102.9MHz from Padang Pauh is also not available in Satun due to its low height elevation, however it may be interfered by high ERP power TP4 (Thor Por Sii/4th Army Area radio) FM 103.0MHz from Trang, Thailand.

Although Satun has no full fledged Malay/Chinese/English radio stations, instead dominated by full Thai language local stations, but this results that Satun has 4 Malay, 1 English, 1 Chinese and 1 Tamil radio stations.

Despite Satun has no Indians, but Raaga is available there via FM 101.9MHz from Gunung Raya.

List of radio stations without Taiping frequency which can be tuned in Taiping, Perak

Majority of radio stations in Malaysia, especially mainstream radio stations have Taiping frequency for Taiping. In Perak state, all mainstream radio stations have Ipoh frequency because Ipoh is the capital of Perak, however Taiping is the second Perak frequency.

Taiping radio stations are transmitted from Bukit Larut.

The reasons of mainstream radio stations have Taiping frequency are:

1. Taiping cannot receive radio stations from Ipoh Gunung Kledang.
2. Although Taiping can receive radio stations from Kedah Gunung Jerai, but some of stations are facing interference from Ipoh Gunung Kledang stations because they have 100kHz frequency separation.

Some of radio broadcasters don't launch Taiping frequency due to market value and unavailability of frequency spectrum there, but they can be listened in Taiping via Penang Bukit Penara or Kedah Gunung Jerai, such as:

1. One FM 87.8MHz (Gunung Jerai)
2. IKIM FM 89.0MHz (Gunung Jerai)
3. Fly FM 89.9MHz (Bukit Penara)
4. Kool FM 90.2MHz (Bukit Penara)
5. Zayan FM 98.1MHz (Gunung Jerai)**
6. goXUAN FM 107.6MHz (Bukit Penara)

** Its predecessor Red FM was used to have Taiping frequency from Bukit Larut on FM 98.2MHz, but closed down since May 2009.

In addition, some of RTM state radio stations outside Perak can be tuned in Taiping such as Kedah FM 97.5MHz and Mutiara FM 93.9MHz from Gunung Jerai.

Other than these Malaysia radio stations without Taiping frequency, Taiping somehow can receive Indonesia and Thailand FM radio stations via tropospheric propagation, but weak signal.
