(IBM: Indonesia Broadcast Matters) Radio Republik Indonesia could launch RRI Pekanbaru PRO-1 repeater in Rokan Hilir regency once TVRI operates DVB-T2 transmission there in 2023. (Some proposal inside)

On previous post, I have talked about TVRI (Televisi Republik Indonesia) will reach coverage in Rokan Hilir regency, Riau Province by building repeater tower this year.

Back to 2021, I had reported about the availability Malaysia radio stations in Rokan Hilir, Riau Province, Indonesia. From 87.5MHz to 108MHz, the frequency band is covered by Malaysia radio stations majority, meanwhile only 1 Indonesia radio station is available there.

Radio Diva Nusantara FM 100.3MHz is the only local radio station in Rokan Hilir regency, transmitted from Bagansiapiapi.

TVRI will launch a DVB-T2 repeater in Rokan Hilir by Q4 2022 or early 2023. Hence, Radio Republik Indonesia can also launch RRI Pekanbaru PRO-1 repeater there after TVRI.

Rokan Hulu and Dumai get covered by RRI Pekanbaru PRO-1 with local repeaters, meanwhile Rokan Hilir (including Bagansiapiapi) has no coverage from RRI stations.

Here is my suggestion of RRI Pekanbaru PRO-1 repeater for Rokan Hilir (ROHIL) in terms of parameter:

- Frequency: FM 107.5MHz

- Transmitter power: 1kW

- Transmitter site: TVRI Rokan Hilir

- Coordinates: 1°52'27.0"N 100°57'31.0"E

By watching Noprio Sandi's video of receiving Malaysia radio station in Rokan Hilir, while Selangor FM 100.9MHz from Gunung Ulu Kali is very clear there, but Pahang FM 107.5MHz from Gunung Ulu Kali is likely not receivable there due to antenna beaming is only for Pahang, Malaysia. So, I suggest FM 107.5MHz for Rokan Hilir transmission.

107.2MHz: Radio Star FM Kota Dumai

107.5MHz: RRI Pekanbaru PRO-1 Rokan Hilir

<300kHz, OK>

107.3MHz: Melody FM Gunung Ledang

107.5MHz: RRI Pekanbaru PRO-1 Rokan Hilir

<200kHz, OK>

107.5MHz: Pahang FM Gunung Ulu Kali

107.5MHz: RRI Pekanbaru PRO-1 Rokan Hilir

<0kHz, OK>

107.5MHz: RRI Pekanbaru PRO-1 Rokan Hilir

107.7MHz: Negeri FM Gunung Ledang

<200kHz, OK>

Here is the expected coverage of RRI Pekanbaru PRO-1 FM 107.5MHz Rokan Hilir repeater (antenna height: 85m).

RRI Pekanbaru PRO-1 FM 107.5MHz from TVRI Rokan Hilir with 1kW power is expected to cover the whole Rokan Hilir regency, from Bagansiapiapi to part of Dumai City.

 

The usage of frequency FM 107.5MHz by RRI Pekanbaru PRO-1 in Rokan Hilir which I recommend will not cause co-channel interference to RTM Pahang FM 107.5MHz Gunung Ulu Kali coverage in Malaysia (especially Selangor coastal areas) because Pahang FM 107.5MHz covers only West Pahang by beaming to east direction only.
