My own research over Minnal FM Bukit Tampin 101.1MHz to solve interference issue in Melaka.

==Current condition of Minnal FM reception in Melaka==

1. Main frequency

103.3MHz: Minnal FM Gunung Ledang 1kW

103.3MHz: Era FM Gunung Ulu Kali 2kW

Result: 0kHz, co-channel interference in Melaka such as Melaka City (St Paul's Hill, Stadhuys, Jonker Street, Dataran Merdeka and high rise buildings within Central Malacca), Tanjung Bidara, Tanjung Kling, Masjid Tanah, Sungai Udang, Kem Terendak, Klebang, part of Alor Gajah.

2. Alternative frequency

90.5MHz: Minnal FM Gunung Telapak Burok 1.5kW

90.6MHz: RRI Pro-1 Bengkalis 5kW

Result: 100kHz, adjacent interference in coastal areas of Melaka including the Malacca City

90.3MHz: Era FM Gunung Ledang 2kW

90.5MHz: Minnal FM Gunung Telapak Burok 1.5kW

Result: 200kHz, clashed by Era 90.3MHz in some Malacca City.

Proposed solution: Adding a lower power transmitter about 500 watts in Bukit Tampin to cover Melaka on FM 101.1MHz where same frequency with Gunung Pulai 101.1MHz.

==Proposed parameter of Minnal FM alternative frequency for Melaka==

- Frequency: FM 101.1MHz

- Power: 0.5kW (500W)

- Transmission site: TM Bukit Tampin

- Height above sea level: 564.5m

- Coverage: Melaka
