My proposals of expanding Asyik FM's coverage in Negeri Sembilan (Gunung Telapak Buruk 95.5MHz) and Ipoh (Gunung Kledang 107.4MHz) can become irrelevant if the proposed frequencies cause interference to existing radio station, but Orang Asli people in Negeri Sembilan and Ipoh can listen to Asyik FM digitally on MYTV CH706 via digital UHF TV signal



From 2018 to 2023, I sent my proposals to RTM for expanding Asyik FM's coverage in Negeri Sembilan, Ipoh and Tapah by following frequencies and transmitters below:


* 107.7MHz Changkat Rembian for Tapah

* 107.4MHz Gunung Kledang for Ipoh

* 95.5MHz Gunung Telapak Buruk for Negeri Sembilan


250W transmitter power is proposed for Gunung Kledang and Gunung Telapak Buruk, meanwhile Changkat Rembian is at 0.5kW.


Until today, I have not received any feedback from RTM regarding my proposals to expand Asyik FM's coverage yet. In the proposals, I attached my antenna pattern drawings which I drew manually based on manufacturer antenna catalogue's vertical polarization pattern, but I just change the antenna direction to prevent interference to existing radio stations. The proposals content are based on my amateur expericne towards radio broadcast, hence I need to get exact interference analysis from professional team of RTM and MCMC.







My proposals can becomes irrelevant if RTM frequency planning team does the analysis of my frequency coverage proposal of Asyik FM for Ipoh (107.4MHz) and Negeri Sembilan (95.5MHz) can cause interference to these radio stations' coverage below:


* Pahang FM 107.5MHz Gunung Ulu Kali coverage in Lipis district and Kampung Sega, Pahang

* Pahang FM 95.5MHz Bukit Sulai in Chini and part of Muadzam Shah, Pahang


For FM 95.5MHz Gunung Telapak Buruk proposal, as there is already a 100kHz frequency separation between Pahang FM 95.5MHz Bukit Sulai and Asyik FM 95.6MHz Gunung Ledang, then the interference between both radio stations happens in Muadzam Shah. The interference will become worse if Asyik FM 95.5MHz Gunung Telapak Buruk transmission is activated, despite low power transmission. Hence, I don't think this proposal goes well and possibly get rejected.


However, Asyik FM is currently digitally available in my proposals such as Ipoh and Negeri Sembilan on MYTV CH706 via digital terrestrial television transmission UHF signal by following frequencies below:


* Ipoh and Kinta Highlands: UHF 650MHz (CH 43) from Gunung Kledang

* Negeri Sembilan: UHF 490MHz (CH 23) for Gunung Telapak Buruk, Bukit Tampin and Gunung Ledang


Orang Asli people in Central Perak can still tune to Asyik FM on MYTV CH706 digitally by receiving signal from Gunung Kledang on UHF 650MHz (Channel 43) with UHF outdoor or indoor antenna.


Alongside MYTV, Asyik FM is also available on Astro or NJOI CH 875, but to me, Astro is not reliable because its satellite transmission faces rain fade attenuation where Astro service will be interrupted when it is raining.


In July 2023, Elon Musk's satellite internet Starlink landed in Malaysia, Orang Asli in remote areas can listen to Asyik FM via online and RTM Klik application with high speed broadband from Starlink.


It is perfect if RTM Asyik FM launches in Ipoh (Gunung Kledang), Negeri Sembilan (Gunung Telapak Buruk) and Tapah (Changkat Rembian) for FM radio transmission, but digital platform such as MYTV CH706, Astro CH875 and online streaming can bypass my proposals.
