RTM should change Asyik FM Gunung Ledang (95.6MHz) and Negeri FM Bukit Tampin (95.7MHz) frequencies as they're intefering each other.

 

 

In Melaka, and some North Johor areas, I spotted Asyik FM 95.6MHz from Gunung Ledang and Negeri FM 95.7MHz from Bukit Tampin were interfering each other.

 

Melaka is having serious interference between Asyik FM 95.6MHz, Negeri FM 95.7MHz and Fly FM 95.8MHz since 2011.

 

95.6MHz: Asyik FM Gunung Ledang (0.25kW)

95.7MHz: Negeri FM Bukit Tampin (0.1kW)

95.8MHz: Fly FM Gunung Ulu Kali (2kW)

 

The interference does not really affect Negeri FM and Fly FM listeners in Melaka because they can tune to 107.7 and 94.0 from Gunung Ledang respectively.

In terms of history, Negeri FM uses 95.7MHz in Bukit Tampin was much earlier than Asyik FM 95.6MHz Gunung Ledang. In addition, Asyik FM launched 95.6MHz in Gunung Ledang 10 years ago only in 2011. Logically, RTM Asyik FM should change its Gunung Ledang frequency.

Next, Negeri FM 95.7MHz Bukit Tampin somewhat was interfered by Fly FM 95.8MHz from Gunung Ulu Kali in Rembau and some area in Kota where they're Bukit Tampin broadcast areas. To cover these areas with more stable reception, RTM Negeri FM should move its Bukit Tampin frequency to 95.6MHz. With this suggestion, Asyik FM has to change frequency too as Negeri FM occupies 95.6MHz in Bukit Tampin.

5 years ago, I proposed RTM to shutdown Negeri FM 95.7MHz Bukit Tampin transmitter with the reason of FM 107.7MHz can cover Rembau and Tampin, but RTM Negeri FM said that some of Rembau areas need Bukit Tampin transmitter because they cannot receive 92.6 and 107.7 clearly. 

Here is my proposal of frequency change for Asyik FM Gunung Ledang and Negeri FM Bukit Tampin transmitters.

==Negeri FM Bukit Tampin frequency change proposal==

* Frequency: FM 95.6MHz (migrate 100kHz from 95.7MHz)

* Power: 0.1kW (same as current, but can upgrade to 0.25kW)

* Result: Asyik FM has to change Gunung Ledang frequency

==RF analysis of Negeri FM 95.6MHz Bukit Tampin==

95.6MHz: Negeri FM Bukit Tampin

95.8MHz: Fly FM Gunung Ulu Kali

<200kHz, OK>

Result: No more interference from Fly FM 95.8MHz Gunung Ulu Kali in Rembau, Pedas and Kota. Better listening, compare to current 95.7MHz.

==Asyik FM Gunung Ledang frequency change proposal==

* Frequency: FM 100.9MHz

* Power: 0.25kW (same as current, but can upgrade to 0.5kW)

* Note: Asyik FM can share antenna system with Johor FM 105.3MHz to provide better transmission coverage.

==RF analysis of Asyik FM 100.9MHz Gunung Ledang==

100.9MHz: Asyik FM Gunung Ledang 0.5kW (mainly North Johor)

100.9MHz: Selangor FM Gunung Ulu Kali

<0kHz, OK>

100.9MHz: Asyik FM Gunung Ledang 0.5kW (mainly North Johor)

101.1MHz: Minnal FM Gunung Pulai

<200kHz, OK>

Results:

1. With frequency and antenna system changes of Asyik FM Gunung Ledang transmitter, Asyik FM can reach more coverage in North Johor, even part of Melaka and Negeri Sembilan, also Pahang.

2. As proposed frequency is same as Selangor FM 100.9MHz, and suggest to share antenna with Johor FM 105.3MHz, Asyik FM Gunung Ledang transmission will not cause interference to Selangor FM 100.9MHz Gunung Ulu Kali coverage in Tanjung Sepat and Sungai Pelek because Asyik FM 100.9MHz beams to Johor mainly like Johor FM 105.3MHz.

Previously I proposed the frequency FM 100.9MHz Gunung Ledang for Pahang FM transmission in Muadzam Shah, Keratong, Selancar...

If RTM changes Asyik FM Gunung Ledang and Negeri FM Bukit Tampin frequencies, there are advantages:

1. Interference will become zero as they're no longer interfering each other.

2. Asyik FM can expand more coverage in North Johor by sharing antenna with Johor FM 105.3MHz in Gunung Ledang after change to proposed FM 100.9MHz. Besides that, Asyik FM can reach more coverage in some Melaka, Negeri Sembilan and Pahang areas. Expect Asyik FM 100.9MHz has better reception than current 95.6MHz.

3. Negeri FM Bukit Tampin transmitter can cover Rembau and Kota even clearer after migrate to 95.6MHz, then no more interference from Fly FM 95.8MHz Gunung Ulu Kali in broadcast areas.

4. Asyik FM may benefit Melaka listeners as it can be listened in part of Melaka, despite it would have interference from Selangor FM 100.9MHz in North Melaka like Johor FM 105.3MHz which interfered by Suria FM 105.3MHz.

==Proposed frequency migration==

* Asyik FM 100.9MHz Gunung Ledang 0.5kW

* Negeri FM 95.6MHz Bukit Tampin 0.25kW

Those frequencies are my personal proposal, but the allocation and actual analysis are decided by MCMC.

RTM state radio stations new logo colour arrangement similarities and differences (April 2021-present)

On 1st April 2021, RTM unveiled its state radio stations brand new logo, each radio station is representing the colour of the state flag respectively. As I figured out its stations old logo colour arrangement similarities and differences on previous post, now I do the same thing by figuring out new logo colour arrangement similarities and differences.

 

Here I figure out the similarities and differences of RTM state radio stations logo colour background arrangement by classifying the major and minor similarities as well as differences.

 

==GROUP 1: Major similarities, but minor differences==

 

GROUP 1A: Selangor FM, Negeri FM, Sarawak FM, Perak FM

* Similarity: All logos background colour are in yellow. Note: Perak FM yellow colour background is darker.

* Difference: All logos are having different lines and "fm" logo colour.

 

GROUP 1B: Johor FM vs. Labuan FM

* Similarity: Both logos background colour are in blue, meanwhile they're same lines colour in red.

* Difference: Both logos are having different "fm" logo colour. 

GROUP 1C: Sabah FM and Johor FM

* Difference: All logos are having different lines and "fm" logo colour.

 

GROUP 1E: Pahang FM and Terengganu FM

- Similarity: Pahang FM and Terengganu FM are using black and white colour in their logo as both state flags are having same colour.

- Difference: By comparing Pahang FM and Terengganu FM new logo, their background colour, lines and "fm Wifi alike logo" are inverse each other.  

GROUP 1F: Johor FM, Sabah FM, Labuan FM

* Similarity: All logos background colour are in blue

* Difference: All logos are having different lines colour. Labuan FM is having different "fm Wifi alike logo" from Johor FM and Sabah FM as it is in yellow.

 

==GROUP 2: Minor similarities, but major differences==

 

Group 2A: Perlis FM and Mutiara FM

 

* Similarity: All lines and "fm WiFi alike logo" colours are in yellow.

* Difference: All logos are having different background colour.

GROUP 2B: Mutiara FM, Kedah FM, Perlis FM

GROUP 2E: Sarawak FM, Sabah FM, Selangor FM, Johor FM, Kedah FM

* Similarity: "fm Wifi alike logo" colour is in red.

* Difference: All logos are having different background and lines colour.

 

GROUP 2F: Labuan FM, Perlis FM, Mutiara FM 

* Similarity: "fm Wifi alike logo" colour is in yellow.

* Difference: All logos are having different background colour. For Labuan FM, it is having different lines colour from Perlis FM and Mutiara FM. 

 

GROUP 2G: Sarawak FM, Negeri FM, Labuan FM, Johor FM, Selangor FM

* Similarity: Lines colour is in red.

* Difference: All logos are having different background and "fm WiFi alike logo" colour (for Labuan FM and Negeri FM).

RTM state radio stations old logo colour arrangement similarities and differences. (2005-2021)

In 2009, when I was 15, I began to discover all RTM (Radio Televisyen Malaysia) state and district radio stations, and recognized their logos, but I spotted that some of state radio stations logo are having colour arrangement similarities during that time. So, I would like to classify their logo colour similarities by group.

Group A: Perlis FM, Mutiara FM, Selangor FM

- Similarity: First three wave colour is in yellow

- Difference: The last wave colour between three are different. Perlis FM is in dark blue, Mutiara FM is in light blue, Selangor FM is in red.

GROUP B: Kedah FM, Negeri FM, Melaka FM, Langkawi FM

- Similarity: First two wave is in red colour, then third wave is in yellow colour.

- Difference: The last wave is different colour. Kedah FM and Langkawi FM are in green, Negeri FM is in black, and Melaka FM is in blue.

GROUP C: Terengganu FM and Kelantan FM

- Similarity: Both of them are full single colour in all waves.

- Differences: Kelantan FM is in red, Terengganu FM is in black. (Both represent the state flag colour respectively)

 

 

GROUP D: Selangor FM, Johor FM and Kelantan FM

- Similarity: The last wave colour of Selangor FM, Johor FM and Kelantan FM logo are in red.

- Difference: First three wave colour for Johor FM is in blue, meanwhile Kelantan FM is in red and Selangor FM is in yellow.

In my opinion, it is good to differentiate by using colour to avoid confusion among each other. Hence, we will not feel confuse of it. For RTM state radio stations' old logo, the colours in the logo are representing the colour of their state flags actually. Example: Perlis FM, the flag of Perlis consists yellow and dark blue. So, the logo of Perlis FM uses these colours.

 

RTM Selangor FM 100.9MHz can be listened in Indonesia (Rokan Hilir, Riau province)

 

RTM Selangor FM 100.9MHz is a state radio station mainly serving Selangor, Malaysia. It can be received in South Perak (Tanjung Malim, Teluk Intan, Tapah), West Pahang (Bentong only) and part of Negeri Sembilan (Seremban/Port Dickson) as well as Melaka. Transmitter site is located in Gunung Ulu Kali (Genting Highlands, Pahang).

 

Surprisingly RTM Selangor FM 100.9MHz can be tuned clearly in Indonesia territory. An Indonesia Youtube user, named Noprio Sandi made a footage of receiving Malaysia radio station in Rokan Hilir, Riau province of Indonesia on 7th November 2020 in his Toyota Cayla.

 

In the footage, most of Malaysia radio stations that he received are transmitted from Gunung Ulu Kali. Until FM 100.9MHz, he recorded the footage longer as Selangor FM played an Indonesia song by Misha Omar, and he listened to the DJ hosting. Hence, I decided to take the clip from the long footage, and published on YouTube with credit.

 

 

According to the footage, RTM Selangor FM 100.9MHz from Gunung Ulu Kali receiving signal is very clear in Rokan Hilir (Rohil), Riau province, Indonesia because it is located in east coast side of Riau province, and there are no terrain between West Coast of Peninsular Malaysia and Indonesia, hence our Malaysia radio stations signal can overspill to Indonesia.

 

Northeast Riau and Southeast North Sumatra province listeners can listen to Selangor FM 100.9MHz loudly and clearly.

 

- Station: RTM Selangor FM

- Frequency: FM 100.9MHz

- Power: 2kW

- Transmitter site: Gunung Ulu Kali, Pahang, Malaysia

- Receiving site: Rokan Hilir, Riau, Indonesia 

 - Distance: 226km

Radio Thailand is going to cease certain AM provincial radio stations and some FM radio stations, it is about 41 stations.

From 01.04.2021, the Thai national broadcaster Radio Thailand will cease certain AM provincial radio stations and some FM stations. According to the sources, there are 41 stations to be closed down, and frequencies will be returned to NBTC.

I'm not certain which regional radio stations are about to be ceased, but I just know there are many Radio Thailand AM stations in southern region and selected FM provincial stations to be closed, also two Bangkok based AM stations too.

==Bangkok based Radio Thailand AM stations to be ceased on 01.04.2021==

* AM 837kHz

* AM 918kHz

==Southern region based Radio Thailand provicial stations to be ceased on 01.04.2021==

* Betong AM 1026kHz

* Surat Thani AM 1215kHz

* Satun FM 99.5MHz

* Satun AM 1206kHz

* Songkhla FM 102.25MHz

* Pattani AM 1296kHz

* Krabi AM 720kHz

* Krabi AM 963kHz (Education network)

* Songkhla AM 558kHz (Education network, but already ceased many years ago)

* Phangnga AM 1341kHz

* Chumphon AM 1377kHz

* Phatthalung AM 864kHz (already off air many years ago)

* Trang AM 810kHz

* Nakhon Si Thammarat AM 639kHz

* Ranong FM 105.75MHz (Education Network)

For other provinces outside Southern Thailand region, most of Radio Thailand AM provincial stations were ceased for a long time. 

I believe the decision of Radio Thailand to shutdown AM broadcasts for provincial stations for following reasons below:

* Less people listen to the stations on poor audio quality AM band due to growing of digital listening

* As selected Radio Thailand provincial AM stations are just simulcast of FM stations, so Radio Thailand decides to reduce duplication by shutting down AM transmission.

After Radio Thailand closed down AM radio stations, I think the broadcaster will improve its exsiting provincial FM stations transmission to reach more coverage and provide clearer reception in the involved provinces respectively.

For Satun province, I don't understand why Radio Thailand Satun closes down FM 99.5MHz, despite 99.5 and 95.5 are different content. After FM 99.5MHz Satun second station is closed down, I suggest Radio Thailand Satun should increase FM 95.5MHz (flagship station in Satun) transmission power to 1kW to 2kW to reach more coverage and listeners. In addition, FM 95.5MHz can reach Malaysia with clearer signal reception.

In Surat Thani, the province will remain only AM 1242kHz (Education Network). In my opinion, Radio Thailand can transfer Surat Thani Education Network from 1242kHz to 1215kHz to avoid interference from Voice of Vietnam VOV-5 AM1242kHz (Can Tho) at night. So, after transition, AM 1242kHz Surat Thani can be closed down, and Education Network continues broadcast on AM 1215kHz in Sura Thani, Thailand.

Besides that, for RF analysis in Thailand-Malaysia border region, as Radio Thailand Songkhla FM 102.25MHz is having 150kHz frequency separation with Malaysia's THR Raaga FM 102.4MHz from Gunung Jerai which causes adjacent channel interference in Perlis and Northern Kedah, Malaysia, there will have no interference when tuning Raaga FM 102.4MHz in North Kedah and Perlis after Radio Thailand Songkhla FM 102.25MHz is closed on 01.04.2021.
