THR Time Highway Radio logo history

THR Time Highway Radio frequency list:

1. THR Raaga

- 99.3MHz: Klang Valley and West Pahang (Gunung Ulu Kali)

- 101.5MHz: Negeri Sembilan and Pahang: Bera (Gunung Telapak Burok)

- 99.7MHz: Melaka, North Johor and South Pahang (Gunung Ledang)

- 103.7MHz: South Johor and Singapore (Gunung Pulai)

- 102.1MHz: North Perak and Taiping (Bukit Larut)

- 102.4MHz: Kedah and Perlis (Gunung Jerai)

- 101.9MHz: Langkawi (Gunung Raya)

- 99.3MHz: Penang (Bukit Penara)

- 97.9MHz: Ipoh, Central Perak and Pahang: Cameron Highlands (Gunung Kledang)

2. THR Gegar

- 88.8MHz: East Pahang (Bukit Pelindung)

- 106.8MHz: Central Terengganu (Bukit Jerung)

- 88.1MHz: Kelantan (Bukit Panau)

THR Gegar untuk Pahang Tengah dan sebahagian Pahang Barat

Pada masa kini, THR Gegar bersiaran di Pahang pada frekuensi 88.8MHz dari Bukit Pelindung, tetapi kawasan liputan hanya untuk Kuantan, Pekan dan sebahagian daerah Rompin.

Kawasan liputan THR Gegar 88.8MHz di Pahang:

- Kuantan
- Gambang
- Cherating
- Kuala Pahang
- Pekan
- Muadzam Shah
- Kuala Rompin

Manakala di kawasan lain negeri Pahang, kebanyakan kawasan tidak dapat menerima siaran THR Gegar akibat jarak jauh dan di luar kawasan liputan 88.8MHz. Kawasan Maran, Temerloh, Jengka, Mentakab, Lipis, Bentong, Jerantut, dan Lanchang memang tidak boleh menerima.

Secara asasnya, THR Gegar boleh menambah pemancar di Gunung Ulu Kali untuk kawasan Pahang Barat, tetapi terdapat berberapa masalah dialaminya:

1. Frekuensi Gunung Ulu Kali telah penuh
2. Status lesen penyiaran THR Gegar tidak meliputi Pantai Barat, akibat stesen bahasa Tamil THR Raaga sudah berada di Gunung Ulu Kali.
3. Status lesen penyiaran THR.FM hanya satu sahaja, iaitu Raaga untuk Pantai Barat, Gegar untuk Pantai Timur.
4. Kapasiti menara pemancar Gunung Ulu Kali telah penuh.

Untuk meliputi kawasan Pahang Tengah dan sebahagian Pahang Barat, THR Gegar perlu menambah 1 pemancar lagi di Bukit Senggora, Maran.

Bukit Senggora banyak frekuensi kosong... 100.7MHz ialah terbaik.

==Cadangan parameter THR Gegar Bukit Senggora==
Frekuensi: FM 100.7MHz
Kuasa: 2kW
Kawasan liputan: Maran, Temerloh, Jengka, Mentakab dan sebahagian daerah Bera/Jerantut/Bentong

==Analisis THR Gegar 100.7MHz Bukit Senggora==
1. Gunung Ulu Kali: 200kHz (100.9MHz, OK)
2. Gunung Telapak Burok: 100kHz (100.6MHz, OK)
3. Gunung Ledang: 200kHz (100.9MHz, OK)
4. Bukit Pelindung: 300kHz (100.4MHz, OK)
5. Bukit Bauk: 0kHz (100.7MHz, OK)

Dengan frekuensi Bukit Senggora THR Gegar FM 100.7MHz, kawasan Temerloh boleh menerimanya asalkan kuasanya tinggi. Kawasan Karak, Bentong, Raub boleh dapat sikit, atau sebaik mungkin seperti menerima Ikim FM di Georgetown pada 102.7Mhz dari Bukit Genting, Balik Pulau yang kurang jelas.

THR Gegar 100.7MHz Bukit Senggora mempunyai 200kHz jarak dengan Selangor FM 100.9MHz dari Gunung Ulu Kali, tiada gangguan yang teruk di Pahang Tengah kerana Selangor FM 100.9MHz untuk Selangor dan Kuala Lumpur sahaja.

Pada Mei 2015, saya pergi ke Bukit Fraser. Apabila saya balik ke Kuala Lumpur dengan melalui jalan Raub dan Bentong, saya boleh menerima sedikit signal Bukit Senggora (guna sampel 92.0, 90.4, 91.2, 87.9 dan 89.6) di Bentong dan jalan Bukit Fraser-Raub. Bukit Senggora mungkin ialah tempat yang terbaik bagi THR Gegar untuk Pahang Tengah dan sedikit kawasan Bentong/Raub/Karak.

Ikim FM 102.9MHz Bukit Penara RF analysis

Since December 2013, I had suggested Ikim FM Bukit Penara frequency before, on FM 102.9MHz.

Because Penang frequencies are limited, only 102.9MHz can be fitted for Ikim FM in Bukit Penara. The 102.9MHz RF analysis has to take care of Bukit Genting and Padang Pauh.

Here is the result of RF analysis of Ikim FM Bukit Penara (vs. 102.7MHz Bukit Genting):

Ikim FM 102.9MHz Bukit Penara has 200kHz with Ikim FM 102.7MHz Bukit Genting, no interference are detected, but has to analyze with Perlis FM 102.9MHz Padang Pauh.

Case1: Bukit Penara 102.9MHz vs. Bukit Genting 102.7MHz

Result: PASSED

Case2: Bukit Penara 102.9MHz vs. Padang Pauh 102.9MHz

About the RF analysis of Case2, co-channel is founded, but the interference to Padang Pauh is depending on power and antenna pattern of Bukit Penara.

Power must be tested with minimum 0.5kW, 1kW and maximum 2kW.

102.9MHz Bukit Penara:

- 0.5kW

- 1kW

- 2kW 

Ikim FM 102.9MHz Bukit Penara mainly targets Georgetown, Seberang Perai, Bayan Lepas, Tanjung Bungah, and North Perak

Media Prima CLSB radio frequency analysis (Kool FM)

After Media Prima acquired Copyright Laureate Sdn Bhd since October 2015, I had suggested few frequencies to them when they would like to broadcast nationwide. Mainly are:

- 107.3MHz: Alor Setar Tower (Central Kedah)
- 105.7MHz: Bukit Larut (Taiping, Kuala Kangsar, Lenggong, Parit Buntar and North Perak)
- 94.9MHz: Gunung Kledang (Ipoh and South Perak)
- 102.1MHz: Gunung Telapak Burok (Negeri Sembilan) or 101.1MHz: Bukit Gan (Seremban)
- 87.6MHz: Gunung Ledang (Melaka and North Johor)
- 107.8MHz/90.9MHz/88.6MHz: Taman Sentosa (Johor Bahru)
- 103.7MHz: Bukit Pelindung (Kuantan)
- 103.6MHz: Bukit Besar (Kuala Terengganu)
- 103.7MHz: Peringat/Bukit Panau (Kota Bharu)

Among these frequencies, 4 of them are passed only, there are 105.7MHz Bkt Larut, 107.3MHz Alor Setar Tower, 102.1MHz Gn Telapak Burok and 103.7Mhz Bukit Pelindung.

Here are the results:

1. Bukit Larut

Results: OK

2. Gunung Kledang

Gn Kledang vs. Gn Brinchang= OK
Gn Kledang vs. Gn Jerai= Failed, antenna pattern and power reduction are needed.

3. Bukit Pelindung

 4. Alor Setar Tower

5. Bukit Besar

Results: NOT OK, 100kHz with Bukit Panau. The frequency of Bukit Panau need to be changed.

6. Gunung Ledang

Recommended frequency for Gunung Ledang: FM 103.9MHz

7. Bukit Panau

Results: FAILED, 50kHz with Narathiwat, Thailand. To be recommend FM 91.4MHz/91.3MHz or 93.4MHz

8. Gunung Telapak Burok

9. Bukit Gan

10. Taman Sentosa Johor Bahru

Results: 90.9MHz, 107.8MHz and 88.6MHz are failed due to interference to Singapore and Batam

Above the result of RF analysis,

1. Bukit Larut 105.7MHz: PASSED

2. Gunung Kledang 94.9MHz: FAILED, but power and antenna pattern reduction are needed

3. Alor Setar Tower 107.3MHz: PASSED

4. Bukit Pelindung 103.7MHz: PASSED

5. Gunung Ledang 87.6MHz: FAILED, To be recommended FM 103.9MHz

6. Bukit Panau 103.7MHz: FAILED, To be recommended FM 87.6/91.4/91.3/93.4MHz

7. Gunung Telapak Burok 102.1MHz: PASSED 

8. Bukit Gan 101.1MHz: PASSED

9. Bukit Besar 103.6MHz: FAILED, but Bukit Panau cannot use 103.7MHz

10. Taman Sentosa Johor Bahru 88.6/107.8/90.9MHz: FAILED

94.9MHz Gunung Kledang must reduce its power to 1kW, and the antenna pattern shall not cover Kuala Kangsar districts.

Media Prima CLSB Gunung Kledang RF analysis (94.9MHz vs. 93.9MHz)

Currently empty FM frequencies in Ipoh/Gunung Ledang are getting limited, so only remain FM 93.3MHz, FM 93.9MHz and FM 94.9MHz.

Because Media Prima acquired Copyright Laureate Sdn Bhd (who operates Pi Mai FM 90.2MHz and Ultra FM 101.3MHz) on October 2015, CLSB will be expected to expand broadcast coverage to nationwide. While launching transmitter everywhere, Ipoh will be listed as well.

For Ipoh and Central Perak, I suggested 94.9MHz based on the spectrum status, but at last it did not pass during analysis test because 94.9MHz from Gunung Kledang interfered to RTM Radio Klasik Gunung Jerai in Kedah.

Look at this map:

 

The RF analysis above indicated that red color stands for the shaded areas of 94.9MHz Gunung Jerai interfered by Gunung Kledang. In addition, RTM Radio Klasik 94.9MHz cover whole Perlis, Kedah and Penang. It is not good if 94.9MHz Gn Kledang interfere Gunung Jerai within service area. So, the antenna pattern of 94.9MHz Gunung Kledang must be reduced or use other frequency like 93.9MHz.

In my opinion, 94.9MHz must not cover Kuala Kangsar to prevent interference to Gunung Jerai, so FM 105.7MHz Bukit Larut has to cover Kuala Kangsar and Sungai Siput.

Gunung Kledang 94.9MHz also shall be reduced to 1kW.

About antenna direction, CLSB only can cover several direction:

- 94.9Mhz Gunung Kledang: South (100%), Southwest (100%), North (15%), Northwest (5%), East (10%)
- 105.7MHz Bukit Larut: East (70%), South (45%), North East (30%), North West (30%)

If 94.9Mhz Gunung Kledang is still fail after adjustment of antenna pattern, CLSB may use 93.9Mhz Gunung Kledang...

Although 93.9MHz Gunung Kledang co-channel with Mutiara FM 93.9MHz Gunung Jerai, but the interference reduced, compare to 94.9MHz because 93.9MHz Gunung Jerai coverage is very small, only cover North Penang.

 

After reading the result of Media Prima CLSB RF analysis, I found that certain transmitters are failed due to interference occurs.

- FM 103.7MHz Bukit Panau (formerly Peringat): FAILED, 50kHz with Narathiwat FM 103.75MHz

- FM 103.6MHz Bukit Besar: FAILED, 100kHz with Bukit Panau unless 103.7MHz did not use in Panau.

- FM 94.9MHz Gunung Kledang: FAILED, CCI to Gn Jerai

- FM 87.6MHz Gunung Ledang: FAILED, CCI to Bukit Pelindung

- FM 88.6MHz/107.8MHz/90.9Mhz Johor Bahru: FAILED, interference with Batam and Singapore.

Minimum separation of FM frequencies in Malaysia.

1. Bukit Panau vs. Bukit Besar: 200kHz

2. Bukit Pelindung vs. Gunung Ledang: 100kHz

3. Gunung Kledang vs. Gunung Jerai: 100kHz 

CLSB failed frequencies must be changed

1. Gunung Kledang: 93.9MHz (if 94.9MHz still interfere to Gunung Kledang after reduce power to 1kW or antenna pattern adjustment)

2. Bukit Panau: FM 92.2MHz

3. Bukit Besar: <Remain same>

4. Gunung Ledang: FM 103.9MHz

5. TM Taman Sentosa: N/A

Suggested parameter of Ikim FM for Penang and North Perak

Currently the reception of Ikim FM is very weak in Penang area when receive 102.7MHz from Bukit Genting, meanwhile 89.0MHz from Lower Jerai is no signal. In my opinion, a transmitter must be set up in Bukit Penara to cover Pulau Pinang and North Perak. Here is my suggested parameters:

==Ikim FM Penang/North Perak==

Frequency: FM 102.9MHz
Power: 2kW
Transmitting location: Bukit Penara (565m)
Coverage: Penang, Seberang Perai, South Kedah (Kulim, Bandar Baharu) and North Perak (Taiping, Parit Buntar)

==RF Analysis 102.9MHz Bukit Penara==

102.9MHz: Ikim FM Bukit Penara
102.9MHz: Perlis FM Padang Pauh
Status: 0kHz, OK

102.9MHz: Ikim FM Bukit Penara
103.1MHz: BFM Alor Setar Tower
Status: 200kHz, OK

102.7MHz: Ikim FM Bukit Genting & Gunung Kledang
102.9MHz: Ikim FM Bukit Penara
Status: 200kHz, OK

102.9MHz: Ikim FM Bukit Penara
103.3MHz: Radio Klasik Bukit Larut
Status: 400kHz, OK

Perlis FM 102.9MHz Coverage

THR Raaga Bukit Larut 102.1MHz can cover some Kelantan areas?

THR Raaga currently has no frequency in East Coast because of licensing conditions, where East Coast airs THR Gegar.

In Kelantan, Terengganu and Pahang, there have no any transmitters there. Pahang still can receive THR Raaga on 99.3MHz from Gunung Ulu Kali in most of west and central areas like Temerloh, Bentong, Raub, Maran, and Jerantut, meanwhile 101.5MHz from Gunung Telapa Burok covers Bera, 99.7MHz from Gunung Ledang Johor covers Muadzam Shah, Keratong and some Rompin districts, 97.9MHz from Gunung Kledang covers Cameron Highlands.

For Kelantan, only some areas still can receive THR Raaga from Perak on 102.1MHz (Bukit Larut) and 97.9MHz (Gunung Kledang), especially Jalan Gua Musang-Cameron Highlands.

Because Bukit Larut height is high, this cause Bukit Larut can transmit to South Perak, Central Kedah and part of Perlis areas. Bukit Larut also can transmit up to some coverage areas of Bukit Bakar (Central Kelantan).

In order to cover Kelantan with existing transmitters, THR Raaga should increase the transmitter power of Bukit Larut frequency 102.1MHz to 10kW, then 102.1MHz can be received in some Kelantan areas.

I had tried to receive THR Raaga 102.1MHz from Bukit Larut in some Selangor areas, such as Sekinchan, Tanjong Karang. It was more stable than 97.9MHz Gunung Kledang transmitter. The transmission of Bukit Larut can results that some Selangor areas can receive from there due to its height.

Bukit Larut= Gunung Ulu Kali No.2

For listeners in Kelantan, have to use high antenna to receive THR Raaga on 102.1MHz from Bukit Larut, but partially reception only.

List of Terengganu areas which can receive Red FM, 988 and one FM from Bukit Pelindung

 

List of Terengganu areas which can receive Red FM, 988 and One FM from Kuantan/Bukit Pelindung:

- Kemaman
- Chukai
- Cheneh
- Cherul
- Kijal
- Kemasik
- Kerteh
- Paka

Frequencies of Red FM, 988 and one FM in Bukit Pelindung:
- 988: 90.4MHz
- one FM: 100.4MHz
- Red FM: 91.6MHz

Dungun totally cannot receive these 3 radio stations. Too far from Kuantan. (109km)

These 3 radio stations have no any frequency in Terengganu states, but one FM may operate a frequency for Kuala Terengganu on 90.1MHz in Bukit Besar.

988登嘉樓收聽頻道的覆蓋範圍

988目前沒有在登嘉樓和吉蘭丹設有任何頻道, 因為這兩個州屬華人非常少. 988比較注重華人多的地區, 尤其是西海岸和東海岸的關丹.. 988最主要的地區是北馬, 中馬, 南馬和彭亨州.

988在關丹的頻率是FM 90.4MHz, 發射地點是Bukit Pelindung. 主要覆蓋範圍是彭亨東部的關丹, 90.4MHz也覆蓋了登嘉樓幾個地區, 特別是甘馬挽縣.

以下可以接收988的登嘉樓地區 (頻率: 90.4MHz):

- Kemaman甘馬挽
- Kijal
- Kerteh
- Kemasik
- Chukai
- Chenah
- Cherul
- Paka

988 FM 90.4MHz進到Dungun地區線路開始差, 甚至完全沒有訊號, 會與瓜拉登嘉樓的愛FM 90.5MHz產生小干擾.

吉蘭丹方面, 988是非常難收的, 南部Gua Musang可能靠比較遠的98.8MHz, 99.8MHz或101.0MHz.
