As today, FM 102.0MHz or FM 102.1MHz is empty and unoccupied in Negeri Sembilan, none of radio stations use these frequencies in Gunung Telapak Buruk for Negeri Sembilan due to interference against other radio stations as I mentioned previously by following below:
* FM 102.0MHz Gunung Telapak Buruk causes Johor FM 101.9MHz Gunung Pulai transmitter to face interference in Central Johor (Sri Gading, Sri Medan, Parit Yaani, Yong Peng, Ayer Hitam and part of Batu Pahat) where 105.3MHz Gunung Ledang reception is less clear.
* FM 102.1MHz Gunung Telapak Buruk causes interference to RTM Melaka FM 102.3MHz (Gunung Ledang) in Northwest Malacca areas like Kuala Sungai Baru, Sungai Udang, Masjid Tanah and Lubok Cina as Melaka FM only operates 1 frequency on FM 102.3MHz for entire Malacca state.
However, the frequency FM 102.1MHz is used by Sepang International Circuit as seasonal Grand Prix live radio commentary during the race event.
Despite FM 102.0MHz or FM 102.1MHz cannot be used in Gunung Telapak Buruk for radio transmission in Negeri Sembilan, but FM 102.1MHz is allowed to be used in Sepang, Selangor for Grand Prix live radio commentary because it only operates seasonally at super low power radio transmission as much as 30W.
Sepang International Circuit (SIC) uses FM 102.1MHz as live radio commentary during MotoGP and recent Formula 1 Bahrain Grand Prix in Malaysia event, as well as other motorsport events. This targets the spectators who are watching F1 or MotoGP at Sepang International Circuit to listen to the live commentary of the race, including the current position of their favorite racers or teams.
Although Sepang has 5G internet coverage, but the data performance would be jeopardized badly due to large crowd of spectators (expected 100k-150k people), so the conventional low powered live commentary radio on FM 102.1MHz can ease this problem. The spectators don't even need to follow up the race status via mobile internet, they can use the portable radio and tune it to FM 102.1MHz for live commentary regarding the race.
The live commentary radio broadcast on FM 102.1MHz from Sepang International Circuit is only operated during motorsport events, it is off air during normal day.
Outside Sepang, the FM 102.1MHz can be tuned in Nilai, Bandar Enstek, Labu, KLIA (Kuala Lumpur International Airport), Salak Tinggi and part of Sungai Pelek, its coverage radius is about 5-10km.
10 years ago, I was used to tune Formula 1 live radio commentary on FM 102.1MHz in Nilai and Labu, Negeri Sembilan, Malaysia. Here are the videos of tuning FM 102.1MHz which I recorded on 2nd October 2016.
On 29th October 2017, I also tuned MotoGP live radio commentary at Sepang International Circuit, but the frequency was FM 102.2MHz (but it was back to 102.1MHz later).
The radio transmission of FM 102.1MHz from Sepang International Circuit is safe from causing interference to licensed radio station as it runs low power transmission at 0.03kW and operates only during motorsport event (usually from Thursday from Sunday).
