Radio Republik Indonesia RRI Batam PRO-1 FM 105.1MHz received in Central and North Johor, Malaysia

We already noticed that Hang FM 106.0MHz was the most powerful Batam radio station in terms of transmission where it can overspill signal in North Johor and part of Melaka with overlapping CityPlus FM 106.0MHz Gunung Telapak Burok signal.

After Hang FM 106.0MHz as powerful station from Batam, actually Radio Republik Indonesia RRI Batam PRO-1 FM 105.1MHz transmission is quite powerful.

From my listening experience, I was used to receive RRI Batam FM 105.1MHz in Gelang Patah and Singapore. In Gelang Patah, Johor, Malaysia, FM 105.1MHz has no interference noise from Ai FM 104.9MHz Gunung Pulai, my phone may have high sensitivity radio receiver. Meanwhile, RRI Batam PRO-1 FM 105.1MHz is very strong in Singapore, cause Ai FM 104.9MHz Gunung Pulai was interfered.

 

Apart of its station availability in Singapore and Southern Johor, actually Central and North Johor are still able to receive RRI Batam PRO-1 FM 105.1MHz.

For RRI PRO-1 Batam FM 105.1MHz in Simpang Renggam, Johor, the entire video was recorded by Badrul Hisham. According to the video, FM 105.1MHz was having adjacent channel interference from Ai FM 104.9MHz Gunung Pulai (local station), despite FM 105.1MHz was receivable there.

Surprisingly, Radio Republik Indonesia RRI Batam PRO-1 FM 105.1MHz was receivable in Northern Johor location named Segamat, the video was recorded by HBC 101, but I published on my YouTube channel by giving credits and video courtesy.

For FM 105.1MHz receiving condition in Segamat, Johor, it was not clear there, but I don't hear any adjacent channel interference noise from RTM Johor FM 105.3MHz Gunung Ledang, despite both are having 200kHz frequency separation only. I may believe the radio receiver are high sensitivity unit in the recordings.

Alongside RRI Batam PRO-1 FM 105.1MHz, its sister station PRO-2 Batam FM 105.5MHz is not receivable in Central and North Johor. Although both are using 5kW transmitter, but PRO-1 and PRO-2 are having different antenna system because PRO-1 antenna gain is higher than PRO-2. So, the effective radiated power (ERP) of RRI Batam PRO-1 FM 105.1MHz is higher than PRO-2 FM 105.5MHz, this allows RRI Batam PRO-1 FM 105.1MHz to have wider coverage and more powerful transmission.
