Mix FM 91.0MHz Gunung Jerai is interfering with RTM Mutiara FM 90.9MHz Bukit Genting each other, but Mix can be tuned via FM 91.3MHz Bukit Larut in affected location.

Based on the audio recording videos above, Mix FM 91.0MHz Gunung Jerai and Mutiara FM 90.9MHz Bukit Genting were interfering each other, I captured this at the cruise (Royal Carribean Mariner of The Seas) between Langkawi and Penang Island while the cruise was going to Phuket, Thailand.

Actually these two videos reflect the interference between both stations within Penang Island too. Mix FM 91.0MHz Gunung Jerai was interfered by RTM Mutiara FM 90.9MHz Bukit Genting in Teluk Kumbar, Balik Pulau and part of Bayan Lepas, meanwhile RTM Mutiara FM 90.9MHz Bukit Genting was interfered by Mix FM 91.0MHz Gunung Jerai in Bayan Lepas and large part of Penang Island, but FM 90.9MHz is not receivable in Georgetown and Seberang Perai (mainland Penang).

Although the minimum frequency separation between Gunung Jerai and Bukit Genting is 200kHz, but interference between Mix 91.0 and RTM Mutiara FM 90.9MHz does not really give impact because both of them have alternative frequency.

In fact, Balik Pulau and Teluk Kumbar somehow cannot receive Mix FM 91.0MHz Gunung Jerai at all, regardless with or without Mutiara FM 90.9MHz Bukit Genting transmission. This is because the locations are topographic enough and full of terrains. However, RTM Mutiara FM 90.9MHz Bukit Genting transmission is strictly for Balik Pulau and Teluk Kumbar, it can be tuned via FM 95.7MHz Bukit Penara which is main transmitter of the station once FM 90.9MHz goes faded and interfered by Mix FM 91.0MHz.

Refer Senn Lens video where he received Hitz FM 92.8MHz Gunung Jerai in Teluk Kumbar, the signal was weak. (Hitz can be tuned via 93.6MHz Bukit Larut).


For Mix FM case, it can be tuned on FM 91.3MHz from Bukit Larut in Teluk Kumbar once FM 91.0MHz was interfered by RTM Mutiara FM 90.9MHz. The receiving signal of Mix FM 91.3MHz Bukit Larut is loud and clear in Teluk Kumbar, Penang. 

Based on my listening experience, I could not listen to Mix in Balik Pulau town on FM 91.0MHz because of Mutiara FM 90.9MHz, but I tuned to FM 91.3MHz Bukit Larut, it was receivable, but not really clear. In my opinion, at least I could continue listening to Mix FM there with 91.3MHz. 

Mix FM 91.3MHz Bukit Larut is not clear as Teluk Kumbar in Balik Pulau town.

Officially, Astro will recommend Mix FM listeners in affected location to continue listening to Mix via Syok app (mobile streaming) and Astro DVR CH855. I agree because two digital platforms provide clearer sound, ideal for indoor listening, meanwhile suggestion to tune FM 91.3MHz Bukit Larut in Balik Pulau is ideal for outdoor, especially in the cars. Besides that, if Balik Pulau is not covered by Internet coverage along the road, so Syok app will not be accessible smoothly, at least FM 91.3MHz is alternative solutions.

In the mean time, I will share with all of you regarding a video which I received Mix FM 91.3MHz in Georgetown, Penang on November 2017.
