Gunung Ulu Kali transmitted radio stations are still receivable in Central Perak, radio signal monitoring was conducted in Tronoh, Seri Iskandar, Bota and Ayer Tawar.

On 8th October 2023, I went to Central Perak to conduct monthly radio signal monitoring (FM DXing), I performed FM DXing in 4 locations such as Seri Iskandar, Tronoh, Bota and Ayer Tawar. 

 

In fact, I plan to come these locations by February 2024 during Chinese New Year holiday, but I make it earlier to this month. This FM DXing trip was 1 day without overnight by departing from Balakong in early morning, then coming back home in the afternoon. Originally this trip only covers Seri Iskandar, Bota and Tronoh in Central Perak, then Chenderiang in South Perak, but I extended my DXing location in Ayer Tawar last minute because I learnt that Ayer Tawar is very near to Bota.

The location route was done by following below:

Balakong (home)>>Teronoh>>Seri Iskandar>>Bota>>Ayer Tawar>>Tanjung Tualang>>Chenderiang>>Bidor>>Balakong (home)

Regarding radio stations that I was DXing, there were nothing very special in Seri Iskandar, Bota, Ayer Tawar and Tronoh, but I focused to DX Gunung Ulu Kali radio stations signal because few of mentioned radio stations don't have tuning frequency nationwide, even in Perak state, such as:

1. BFM 89.9

2. GoXUAN FM 88.9

3. RTM Selangor FM 100.9MHz

4. RTM Pahang FM 107.5MHz

5. RTM Asyik FM 102.5MHz

Best FM 104.1MHz signal videos were not filmed because it had co-channel interference with Perak FM from Bukit Larut in Seri Iskandar, Teronoh, Bota and Ayer Tawar. In addition, Best FM was playing non-stop music with less advertisement, so I could not stay for so long to wait for footage recording when the songs were ended due to limited time given.

Between Selangor FM 100.9MHz and Pahang FM 107.5MHz, by overall conducting the radio signal strength check, Selangor FM 100.9MHz is stronger than Pahang FM because Pahang FM beams to east (Pahang) from Gunung Ulu Kali, meanwhile Selangor FM 100.9MHz beams to west (Selangor) from Gunung Ulu Kali.

 

Selangor FM 100.9MHz signal is clear in Tronoh, Bota and Ayer Tawar without interference of 988 FM 101.0MHz from Bukit Larut like Seri Iskandar.

Next, Asyik FM 102.5MHz signal is moderate in Tronoh, but it was very weak in Ayer Tawar, Seri Iskandar and Bota. I don't understand the radio reception of Asyik FM 102.5MHz from Gunung Ulu Kali in Tronoh is clearer than other locations of Southern Perak such as Chenderiang, Bidor, Teluk Intan, Bota, Ayer Tawar and Seri Iskandar, the radio propagation seems weird actually. In Ayer Tawar, Asyik FM 102.5MHz has adjacent channel interference with Gunung Jerai transmitted THR Raaga FM 102.4MHz. 

Asyik FM 105.1MHz Cameron Highlands frequency from Gunung Brinchang could not be tuned in Tronoh, Seri Iskandar, Bota and Tanjung Tualang like Radio Klasik FM 89.1MHz due to its transmitter system is having issue.

BFM 89.9 is overall clear in Seri Iskandar, Ayer Tawar, Tronoh and Bota, but it has adjacent channel interference with Traxx FM 90.1MHz from Gunung Kledang when I tuned in Tronoh. From Bota to Ayer Tawar, even in Ayer Tawar town, BFM 89.9 is interfered by Fly FM 89.9MHz from Penang's Bukit Penara.

In Bota, all the radio stations signal videos were filmed at Bota Kiri.

 

Gunung Ulu Kali radio signal is clearer than Bukit Larut in these 4 locations. 

 

==Receiving distance of Gunung Ulu Kali radio signal to 4 locations in Central Perak==

1. Tronoh: 142km

2. Seri Iskandar: 138km

3. Bota: 143km

4. Ayer Tawar: 150km

After 4 locations, during the departure to Balakong in Selangor, I also passed by Tanjung Tualang and stopped in Chenderiang (South Perak location).

Asyik FM 102.5MHz is available in Tanjung Tualang, but signal is not strong as Ai FM 106.7MHz and MY FM 101.8MHz.

I will be coming back to Perak again in November 2023 with another series of FM radio DXing with the locations namely Pangkor Island, Lumut, Seri Manjung, Sitiawan town, Pantai Remis, Changkat Keruing and Selama.
