So, I was going to ask for inquiry to RTM by sending email with few attachments regarding FM 92.0MHz transmission. So, I got replied from RTM. The broadcaster stated that FM 92.0MHz was transmitted from Hulu Langat as gap filler transmitter to cover Hulu Langat where some of areas are not covered by existing transmitters such as Gunung Ulu Kali, Gunung Telapak Burok and Kuala Lumpur Tower.
At the same time, Selangor FM does have Hulu Langat frequency on 99.8MHz. Both of them are operating at lower power, not more than 250W, I guessed.
==Current RTM Hulu Langat radio stations==
* 92.0MHz: Nasional FM
* 99.8MHz: Selangor FM
Moreover, Hulu Langat has more Orang Asli residents where stay at the villages. In my opinion, RTM still can add pocket filling transmitter for Asyik FM in Hulu Langat 18th miles (Batu 18) to cover blind spot areas.
Because FM 102.0MHz is likely occupied in Bukit Tampin as army general broadcast radio station, so FM 102.1MHz cannot be used in Gunung Telapak Burok, but FM 102.2MHz is suitable to be used in Hulu Langat with this situation.
==My parameter suggestion for Asyik FM Hulu Langat==
* Frequency: FM 102.2MHz
* Power: 0.5kW
* Transmitter site: Batu 18, Hulu Langat, Selangor
* Coverage: Hulu Langat and surrounding areas. Also works as alternative frequency of 91.1MHz and 102.5MHz when the reception of both existing frequencies are not clear.
