Hot FM 99.5MHz from Gunung Telapak Buruk (Negeri Sembilan) received in Bintulu, Sarawak via Sporadic E propagation.

 

In Sarawak, Hot FM broadcasts only in Kuching on 94.3MHz, transmitted from Gunung Serapi, it is also receivable in Saratok District of Betong Division, part of Sri Aman and Serian.

 

Two weeks ago, I had managed to receive Hot FM 94.3MHz signal in 6 areas of Sarawak such as Simanggang, Engkilili, Pakan, Debak, Roban and Saratok, but recently the Bintulu radio DXer, Shafik1995 tuned Hot FM in Bintulu, Sarawak on the frequency 99.5MHz from Gunung Telapak Buruk, Negeri Sembilan on 30th May 2025.

 

The signal of Hot FM 99.5MHz was clear with statics in Bintulu, Sarawak without the adjacent channel interference noise of local radio station (Ai FM 99.3MHz from Bukit Setiam).

 

Hot FM 99.5MHz Gunung Telapak Buruk transmitter radio reception in Bintulu, Sarawak which received on 30th May 2025 was an overspill signal in Sporadic E propagation.

 

There was no adjacent channel interference noise of RTM Ai FM 99.3MHz Bukit Setiam transmitter when tuned to Hot FM 99.5MHz in Bintulu, Sarawak because:

 

1. The sensitivity of the radio receiver by Shafik1995 is very high, it can eliminate the interference noise of the adjacent station. At 100kHz frequency separation between distant and local radio stations, certain radio receivers have no interference at all.

 

2. Bukit Setiam is located in Tatau, Sarawak. It is 26km to Bintulu town. Hence, there is no obvious interference noise, but if we tune to Hot FM 99.5MHz Sporadic E signal from Gunung Telapak Buruk in the vicinity of Bukit Setiam, surely we will hear the interference noise.

3. Inversely if RTM Ai FM 99.3MHz is transmitted from Bukit Nyabau, instead of Bukit Setiam, I think Shafik1995 would detect the interference noise of this radio station when he tuned Hot FM 99.5MHz in Bintulu, Sarawak.
