Co-channel interference between Suria FM (TX_Gunung Ulu Kali) and RTM Johor FM (TX_Gunung Ledang) on the frequency 105.3MHz in Pedas Linggi, Negeri Sembilan (2026)

 

This is my video of detecting co-channel interference between RTM Johor FM (Gunung Ledang) and Suria FM (Gunung Ulu Kali) in Pedas Linggi, Negeri Sembilan on 17th May 2026 when I was driving to Yong Peng, Johor.

RDS PS text was changed from "JOHOR FM" to "SURIA" when I tuned 105.3MHz in Pedas Linggi, then the RDS PS text disappeared during co-channel interference.

From Seremban to Muar, co-channel interference between Johor FM and Suria on 105.3MHz extends until Simpang Ampat toll exit in Malacca.

1. Suria FM is already tuned on 107.0MHz (Gunung Telapak Buruk) or 88.5MHz (Gunung Ledang) in Pedas Linggi, Negeri Sembilan

2. RTM Johor FM 105.3MHz only covers North Johor, co-channel interference with Suria FM in Negeri Sembilan and Melaka is considered normal. Listeners can access RTM Johor FM via RTM Klik or online streaming.
