RF analysis: FM 103.1MHz Lower Jerai vs. FM 103.1MHz Alor Setar Tower (BFM)

==Parameters==
Frequency: FM 103.1MHz
Power: 0.5kW
Transmitting location: Lower Jerai/Alor Setar

==Stations involved RF analysis==
1. Perlis FM 102.9MHz Padang Pauh
2. Ikim FM 102.9MHz Bukit Penara
3. Thailand Parliament Radio 103.25MHz Songkhla
4. Radio Klasik Bukit Larut 103.3MHz

==RF analysis 103.1MHz Lower Jerai==

1. VS Ikim FM Bukit Penara 102.9MHz

Separation: 200kHz
Critical level: LOW
Antenna direction of 103.1MHz: North

2. VS Perlis FM Padang Pauh

Separation: 200kHz
Critical level: Medium

3. VS Thailand Parliament Radio Songkhla 103.25MHz

Antenna direction: South
Spacing: 150kHz
Critical level: Low

Antenna direction: North
Spacing: 150kHz
Critical level: High

==RF Analysis 103.1MHz Alor Setar Tower==

1. VS 102.9MHz Bukit Penara & Padang Pauh

Both separation are 200kHz, no critical issue is detected.

2. VS. Songkhla 103.25MHz

Frequency separation is 150kHz, low critical level.

In conclusion, 103.1MHz located in Alor Setar Tower is safer than Lower Jerai because Lower Jerai can interfere 102.9MHz and 103.25MHz.

Media Prima 4th radio station (CLSB) will be launched on 3rd March 2016

Since October 2015, Copyright Laureate Sdn Bhd (CLSB) owned radio stations, Ultra and Pi Mai FM were acquired by Media Prima. Recently, the radio station is on trial transmission and counting down for launching new stations.

Last week, some of Hot FM DJs (including Fara Fauzana aka Fafau) moved to CLSB stations.

Previously everybody is speculating what will CLSB station become. 

My own speculation is Media Prima will launch CLSB radio as Malay language station, which targets serious and mature attitude listeners. Media Prima stated that they will launch this station on 3rd March 2016.

I had tried to tune to this station, my area is FM 101.3MHz.. 

About the frequencies, they just only mentioned 101.3MHz Klang Valley and 90.2MHz Penang. I'm  really not sure about when they are launched, will they mentioned more frequencies. 

They could launch these transmitters site:

- Alor Setar Tower (Alor Setar)

- Gunung Telapak Burok/Bukit Gan (Negeri Sembilan)

- Gunung Ledang (Melaka/Johor)

- Bukit Pelindung (Kuantan)

- Peringat (Kota Bharu)

- Bukit Besar (Kuala Terengganu)

- Bukit Larut (Taiping)

- Bukit Karatong (Kota Kinabalu)

- Bukit Djin (Kuching)

- Gunung Kledang (Ipoh)

But it is very difficult to make frequency for Johor Bahru as no available frequencies. It seems Media Prima may be unable to reach Johor Bahru for its 4th radio stations.

I had suggested FM 90.9MHz, FM 88.6MHz and FM 107.8MHz. All of them were failed due to interference with Singapore and Batam stations.

Basically FM 107.9MHz can be used in Gunung Pulai. Because of FM 107.9MHz frequency is near to Singapore/Johor Bahru airport airband, it cannot be used. Otherwise, it will cause flight accident as 107.9Mhz interfered to airband. 

88.6MHz basically can be fitted, but heavily interfered by Singapore stations (88.3 and 88.9) as 300kHz spacing.

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
