Verified: RTM Nasional FM 92.0MHz and Selangor FM 99.8MHz Hulu Langat Batu 18 transmitters were terminated.

On January 2018, we had spotted RTM Nasional FM 92.0MHz and Selangor FM 99.8MHz operated as additional frequencies within Selangor apart from existing frequencies (88.5MHz and 95.3MHz for Nasional FM; 100.9MHz for Selangor FM).

Actually RTM Nasional FM 92.0MHz, and Selangor FM 99.8MHz were transmitted from Hulu Langat Batu 18 transmitter tower as pocket filling transmitters to cover blind spot areas within Hulu Langat town where the locations may not receive Gunung Ulu Kali signal clearly.

Firstly I already noted RTM Nasional FM 92.0MHz where I spotted in Balakong and Serdang on 25th September 2017, but I had no idea where the location transmitted from yet. Until I sent an inquiry to RTM, I was told that Nasional FM 92.0MHz transmitted from Hulu Langat Batu 18, alongside with Selangor FM 99.8MHz since 10th January 2018 (which was my 24th years old birthday).

Nasional FM 92.0MHz and Selangor FM 99.8MHz from Hulu Langat could be received in Balakong, Cheras, and part of Kajang/Serdang/Puchong, but signals were not clear. 

Selangor FM 99.8MHz receiving signal was interesting actually. As Balakong is not far from Hulu Langat, but Selangor FM 99.8MHz was interfered with THR Raaga FM 99.7MHz from Gunung Ledang each other in Balakong, Selangor. Raaga FM 99.7MHz Gunung Ledang was having 120km distance from Balakong.

Until May 2019, Nasional FM 92.0MHz and Selangor FM 99.8MHz Hulu Langat transmitters were closed down and off-air. I thought they were just a transmission repairing and would be returned on air soon, but they were still off-air after I came back from Brisbane, Australia on August 2019.

From May 2019 until today, Nasional FM 92.0MHz and Selangor FM 99.8MHz Hulu Langat transmitters are still off-air. This indicates that RTM has terminated Hulu Langat gap filler radio stations for Nasional FM and Selangor FM, but Nasional FM and Selangor FM can be received in Hulu Langat town via 95.3MHz and 100.9MHz from Gunung Ulu Kali respectively, the receiving signal condition of both status is still fine there. In my opinion, I may think that very less people note that Nasional FM and Selangor FM had gap filler transmitter in Hulu Langat as they already tuned to Gunung Ulu Kali frequency very early.


My final radio aircheck of Selangor FM 99.8MHz Hulu Langat was back to March 2019, but I will share some signal aircheck of RTM Hulu Langat videos where I recorded between 2017 and 2019 as a flashback.

After RTM terminated Hulu Langat 92.0 and 99.8 since May 2019, actually this may free up some radio frequency in Klang Valley. The new radio broadcaster can apply new frequency in Klang Valley with 91.9MHz and 99.7MHz, but not transmitted from Bukit Sungai Besi, Kuala Lumpur Tower and Gunung Ulu Kali. FM 91.9MHz and 99.7MHz are only allowed to cover Kuala Lumpur city with low power transmission like One FM 88.3MHz Bukit Gun covers Seremban only. 

91.9MHz and 99.7MHz can be used in Bukit Lanjan to cover Klang Valley.
