Outside Kuching, Hot FM 94.3MHz can be tuned in Northern Betong Division (Saratok, Kabong & Roban) and part of Sri Aman Division (Simanggang & Engkilili)

Do you know? Malaysia's No.1 radio station, Hot FM can be received in Northern Betong Division and part of Sri Aman Divison via 94.3MHz from Gunung Serapi.

 

In Sarawak, Hot FM only broadcasts in Kuching on the frequency 94.3MHz, transmitted from Gunung Serapi. Its main coverage areas are Kuching, Bau, Sematan, Kota Samarahan, Simunjan, Sebuyau and part of Serian.

 

In Betong and Sri Aman Divisions, Hot FM 94.3MHz can be tuned in Kabong, Roban, Saratok, Pusa, Maludam, Engkilili, Simanggang, Lingga and part of Debak. 

 

1. Simanggang (147km)

 

2. Engkilili (172km)

 

3. Debak (138km)

 

4. Saratok (129km)

5. Roban (129km)

6. Kabong by Sarawak Radio & TV (106km)

Among 5 receiving locations in Sarawak, Saratok is the best town to receive Hot FM 94.3MHz from Gunung Serapi. It is loud and clear in Saratok, Sarawak with STEREO signal. Although Hot FM 94.3MHz has 100kHz frequency separation with RTM Sarawak FM 94.4MHz Off Spaoh transmitter, but there had no interference noise of RTM Sarawak FM 94.4MHz when I was listening to Hot FM 94.3MHz in Saratok on 19th May 2025 before departing to Sibu.

Hot FM 94.3MHz is slightly weaker in Roban and Engkilili, compare to Saratok.

 

I had not approached Kabong and Pusa as they were not listed in my locations of FM DX: Sarawak 2025 (PART 1). As Kabong and Pusa are located at coastal areas of Betong Division, but I may believe that Hot FM 94.3MHz is louder and clearer there because Gunung Serapi radio transmission can overspill signal to Kabong, Madulam and Pusa.

In Debak and Simanggang, Hot FM 94.3MHz Gunung Serapi transmitter has adjacent channel interference noise from RTM Sarawak FM 94.4MHz Off Spaoh transmitter. Before having breakfast at a restaurant in Simanggang town by eating my favorite Mee Pok, I monitored Hot FM 94.3MHz signal by using car radio. If I used TECSUN PL-380 and PL-310ET radio receiver to tune Hot FM 94.3MHz in Simanggang, the frequency was completely interfered by Sarawak FM 94.4MHz.

RTM Sarawak FM 94.4MHz Off Spaoh transmitter has clear distant signal in Simanggang town, causing Hot FM 94.3MHz has interference from this radio station. The main coverage of RTM Sarawak FM 94.4MHz Off Spaoh transmitter are Debak, Spaoh and Betong. In Saratok, Sarawak FM can be tuned loudly and clearly via 91.5MHz from Bukit Kayu Malam when 94.4MHz is interfered by Hot FM 94.3MHz, meanwhile 100.3MHz from Bukit Temudok has moderate signal there.

On Pan Borneo Highway, from Kuching to Sibu, Hot FM 94.3MHz can be tuned clearly until Sri Aman (Simanggang), then adjacent channel interference with Sarawak FM 94.4MHz Off Spoah transmitter starts from Temudok to Debak. In Spaoh and Betong, Hot FM 94.3MHz cannot be tuned totally due to Sarawak FM 94.4MHz. After that, Hot FM 94.3MHz is available again from Debak to Roban when RTM Sarawak FM 94.4MHz becomes weak in Mendas (area between Saratok and Debak).

 

Hot FM 94.3MHz coverage availability in Sarawak (based on Pan Borneo Highway):

1. Kuching>>Serian 

2. Serian>>Sri Aman (weak signal) 

3. Sri Aman>>Betong (interference with RTM Sarawak FM 94.4MHz Off Spaoh transmitter)

4. Betong>>Debak (signal is completely null due to Sarawak FM 94.4MHz)

5. Debak>>Roban (moderate signal)

6. Roban>>Sebangkoi (frequency leakage signal from Bukit Kayu Malam transmitters, RTM or Cats FM)

7. Sebangkoi>>Pakan (no signal)

8. Pakan>>Bintangor (weak signal)

 

In Sarikei Division, Hot FM 94.3MHz signal can be detected weakly near Pakan, Sarawak when I drove to Sibu on Pan Borneo Highway.
