After Tampin, Negeri Sembilan was the first ever Malaysia location that I received RRI PRO-1 Bengkalis FM 90.6MHz, surprisingly I receive this radio station again at my home in Balakong, Selangor (20km from Kuala Lumpur) today.
Actually I have no plan to do a far FM DXing today, instead just perform radio aircheck of UPM Putra FM 90.7MHz at home on my TECSUN PL-380 radio receiver, but UPM Putra FM 90.7MHz is off-air.
When UPM Putra FM 90.7MHz is off-air, I receive an adjacent noise of unknown radio station which likely speaking Malay language. Therefore, I suspect the radio station is from RRI PRO-1 Bengkalis FM 90.6MHz because there is no any radio station within my location uses FM 90.7MHz other than UPM Putra FM. I slowly tune the frequency to FM 90.68MHz and below, then match with RRI PRO-1 Bengkalis FM 90.6MHz online streaming content through mobile phone, it is positively verified.
During the video recording, Radio Republik Indonesia RRI PRO-1 Bengkalis FM 90.6MHz is going to air Muslim afternoon prayer (Azan Zohor) around 1305 hours (UTC+8; Malaysia/China/Singapore/Taiwan/Hong Kong time).
In this video, I receive Radio Republik Indonesia RRI PRO-1 Bengkalis FM 90.6MHz via Tecsun PL-380 receiver, while antenna is pointing towards southwest direction from my position. To receive this radio station, I must stay in stationary and correct position, otherwise FM 90.6MHz will be fully overlapped by RTM Minnal FM 90.5MHz from Gunung Telapak Burok, Negeri Sembilan.
In Balakong, in fact Minnal FM 90.5MHz from Gunung Telapak Burok is very clear, so RRI PRO-1 Bengkalis FM 90.6MHz has adjacent channel interference noise from Minnal FM 90.5MHz.
The interference from Minnal FM 90.5MHz on RRI PRO-1 Bengkalis FM 90.6MHz which I receive in Balakong, Selangor, Malaysia can be reduced by adjusting the receiver frequency to FM 90.65MHz, FM 90.68MHz on TECSUN PL-380.
It is not receivable most of the time when UPM Putra FM 90.7MHz returns transmission. Due to Covid-19 pandemic, the campus and education sectors are closed, therefore UPM Putra FM 90.7MHz is temporarily off-air. For your information, UPM Putra FM 90.7MHz is a campus radio station by UPM, under RTM broadcast license, it is also known as "RTM Selangor FM Saluran UPM", it only broadcasts on weekdays from 10am till 8pm, it is in silent mode or off-air during non-broadcasting hours.
RRI PRO-1 Bengkalis FM 90.6MHz is likely receivable in coastal areas of Melaka and Johor.
