RTM Radio Klasik has frequency in Lenggong, Perak. FM 89.9MHz from Bukit Ladang Teh?

As I know that RTM operates 3 radio stations in Bukit Ladang Teh transmission site to cover Lenggong, Perak, they're operates 0.5kW power. The radio stations are Nasional FM 92.3MHz, Asyik FM 93.1MHz and Perak FM 94.2MHz.

When I was in Sungai Siput (U), majority I detected Bukit Larut and Gunung Kledang radio signals, but selected Bukit Ladang Teh stations signal could be detected. Asyik FM 93.1MHz is the strongest one, BUT I detected Radio Klasik FM feeds on 89.9MHz in Sungai Siput (U), Perak.

This is another new Radio Klasik frequency that I spotted in Sungai Siput (U). Currently Radio Klasik operates FM 103.3MHz Bukit Larut, 88.3MHz Gunung Kledang, 90.3MHz FELDA Terolak (Timur), 90.7MHz Ulu Slim, 90.7MHz Sungai Siput (U), 97.8MHz Gerik and 88.7MHz Changkat Rembian in Perak state.

I may suspect FM 89.9MHz Radio Klasik signal is transmitted from Bukit Ladang Teh, Lenggong, Perak. In Lenggong, Radio Klasik 89.9 is the fourth RTM radio station.

In another way, FM 89.9MHz that I detected in Sungai Siput (U) could be the fake signal. RTM Sungai Siput (U) repeater's radio stations Nasional FM 89.5 and Radio Klasik 90.7MHz may not have band pass filter, to cause transmission signal leak to other frequencies, but the possibility is low because:

89.9MHz: Radio Klasik (currently suspect from Bukit Ladang Teh)

90.7MHz: Radio Klasik Sungai Siput (U)

<0.8MHz>

Radio stations with 0.8MHz frequency separation will not leak signal to cause interference (regardless with or without installing band pass filter) and the maximum frequency deviation is 75kHz +/-. The broadcast stations only install band pass/high pass filter when the separation is 500kHz and below to control frequency harmonic.

If there is no frequency leakage, Radio Klasik FM 89.9MHz is transmitted from Bukit Ladang Teh, Lenggong.

Here is the parameter:

- Station: Radio Klasik

- Frequency: FM 89.9MHz

- Transmitter site: Bukit Ladang Teh, Perak

- Target area: Lenggong, Perak
