RTM Miri FM 95.7MHz from Bukit Lambir suffers adjacent channel interference from RTM Nasional FM 95.5MHz in Long Lama, Sarawak, so RTM Nasional FM should change its Long Lama frequency to avoid interference.

Since 2016/17, RTM Nasional FM launched its gap filler transmitter in Long Lama, Sarawak on the frequency FM 95.5MHz, this has already caused RTM Miri FM 95.7MHz Bukit Lambir transmitter suffers strong adjacent channel interference in Long Lama.

In my opinion, it is caused by the poor frequency planning of MCMC about the frequency assignment for RTM Nasional FM's gap filler transmitter in Long Lama, Sarawak.

95.5MHz: RTM Nasional FM Long Lama

95.7MHz: RTM Miri FM Bukit Lambir

<200kHz, NOT OK>

Long Lama should be separated its frequency at least 400kHz from Bukit Lambir, instead of 200kHz or 300kHz.

When RTM Miri FM 95.7MHz Bukit Lambir transmitter is interfered by RTM Nasional FM 95.5MHz in Long Lama, Sarawak, there is no alternative frequency for Miri FM in Long Lama.

For Radio Kayan and Talidio Kenyah program, the listeners can tune alternatively on SW 11665kHz in Long Lama, alongside RTM Klik or Astro CH871.

RTM Miri FM has no gap filler transmitter in Long Lama like Nasional FM 95.5MHz and Sarawak FM 98.1MHz.

To solve this issue, as there are a lot of empty frequency slots in Long Lama, RTM Nasional FM should change its Long Lama frequency to avoid interference against RTM Miri FM 95.7MHz Bukit Lambir transmitter's coverage in Long Lama, Sarawak.

Empty frequencies in Long Lama, Sarawak:

* 87.6MHz

* 94.7MHz

* 97.3MHz

* 99.1MHz

* 100.1MHz
