RTM Wai FM Bidayuh is still tuned on 106.1MHz from Gunung Serapi in Sebuyau, Sarawak.

In Sebuyau, Sarawak, RTM Wai FM Bidayuh is still tuned on 106.1MHz from Gunung Serapi transmitter.

Few days ago, Cock DXer uploaded a video of tuning RTM Wai FM Bidayuh 106.1MHz and 101.7MHz in Sebuyau, Sarawak.

Based on the video, RTM Wai FM 106.1MHz is louder and clearer than 101.7MHz in Sebuyau, Sarawak.

* 106.1MHz is transmitted from Gunung Serapi at 1kW transmitter power, it mainly serves Kuching.

* 101.7MHz is transmitted from Gunung Ampungan for Serian at 0.25kW transmitter power.

Receiving distance of RTM Wai FM Bidayuh in Sebuyau, Sarawak 

* FM 106.1MHz Gunung Serapi: 84km

* FM 101.7MHz Gunung Ampungan: 54km

Although the receiving distance from Gunung Serapi to Sebuyau is further than Gunung Ampungan to Sebuyau, but the signal of Gunung Serapi radio station is clearer because the height of Gunung Serapi is more than Gunung Ampungan, then RTM Gunung Serapi operates a higher transmitter power than Gunung Ampungan. In addition, RTM reduces the transmitter power of Gunung Ampungan radio station from 0.5kW to 0.25kW since 2023 after the transmitter system upgrade.

Wai FM Bidayuh 101.7MHz Gunung Ampungan is very weak in Sebuyau, Sarawak.

By comparing with my video of tuning Wai FM Bidayuh in Sri Aman (Simanggang) and Engkilili where I recorded on 19th May 2025, actually 106.1MHz is also clearer and better than 101.7MHz in Lingga, Sarawak.

Lingga is a small town in Sri Aman Division, located between Sebuyau and Simanggang (Sri Aman).

From here, Wai FM Bidayuh 101.7MHz from Gunung Ampungan is only covering Serian and Tebedu, meanwhile Siburan which is under Serian Division is covered by Gunung Serapi transmitter on 106.1MHz because 101.7MHz is not so clear in Siburan.

Same as Sebuyau, Wai FM Bidayuh is also tuned on 106.1MHz from Gunung Serapi in Simunjan and Asajaya.
