Bukit Senggora empty FM frequencies analysis

In Bukit Senggora, there has some empty frequencies.

Here are the list of empty FM frequencies, based on FM scanning and spectrum condition:

- FM 93.7MHz
- FM 99.7MHz
- FM 100.7MHz
- FM 104.4MHz

1. FM 93.7MHz

- 200kHz with FM 93.9MHz. If Bernama Radio24 transmits from Gunung Ulu Kali on 93.9MHz, FM 93.7MHz cannot be received clearly in Temerloh from Bukit Senggora, even no signal.
- 100kHz with FM 93.6MHz Gunung Ledang. Not clear in Temerloh

2. FM 99.7MHz
- 400kHz with Gunung Ulu Kali 99.3MHz and 100.1MHz
- 300kHz with Bukit Pelindung 100.0MHz
- 200kHz with Gunung Telapak Burok FM 99.5MHz
- Suitable for gap filler stations (RTM Ai FM Bukit Senggora)
- My suggested frequency for Ai FM Bukit Senggora as current 89.6MHz interferes with IKIM FM Bukit Pelindung in areas between Kuantan and Maran

3. FM 100.7MHz
- 200kHz with Gunung Ulu Kali 100.9MHz
- 300kHz with Bukit Pelindung 100.4MHz
- 100kHz with Gunung Telapak Burok FM 100.6MHz
- Suitable for gap filler stations (RTM Minnal FM Bukit Senggora)
- My suggested frequency for Minnal FM Bukit Senggora as current 90.4MHz interferes with IKIM FM Bukit Pelindung in areas between Kuantan and Maran
- Previously suggested for THR Gegar, but it seems not effective much because Temerloh receives My FM 100.6MHz Gn Telapak Burok signal.

4. FM 104.4MHz
- 300kHz with Gunung Ulu Kali 104.1MHz
- 300kHz with Bukit Pelindung 104.1MHz and 104.7MHz
- 100kHz with Gunung Telapak Burok 104.6MHz
- Suitable for commercial broadcasting like THR Gegar.

Previously I had published about my opinion of THR Gegar Bukit Senggora frequency for Central Pahang like Temerloh, Maran, Jengka, Mentakab and Bera on FM 100.7MHz. During Pahang trip on Deepavali 2016, I noticed that Temerloh cannot receive any signals from Bukit Senggora by testing Pahang FM 92.0MHz, and Nasional FM 91.2MHz.

RTM Bukit Senggora power is 0.5kW, that's small coverage.

In my opinion, Temerloh may receive Bukit Senggora signal if occupied 2kW.

Imagine if THR Gegar used my former suggested frequency FM 100.7MHz with 2kW power in Bukit Senggora, I don't think Temerloh can receive the station and it will cause interference there as My FM 100.6MHz from Gunung Telapak Burok is still very clear there.

Moreover, frequencies in Central Pahang are limited enough. I don't think it is effective to cover Temerloh and some West Pahang areas if use the frequencies which 200kHz with Gunung Ulu Kali. Basically FM 93.7MHz can be used for commercial broadcasting (2kW) in Bukit Senggora if Bernama Radio never use Gunung Ulu Kali. Inversely, if Bernama Radio use 93.9MHz in Gunung Ulu Kali, FM 93.7MHz Bukit Senggora is not clear in Temerloh.

Another frequency, FM 100.7MHz Bukit Senggora. Selangor FM 100.9MHz Gunung Ulu Kali uses directional antenna to cover Selangor only, meanwhile Pahang is not so clear. Although commercial radio uses FM 100.7MHz Bukit Senggora, it has no problem if 200kHz with Gunung Ulu Kali 100.9MHz, but it will be interfered by My FM 100.6MHz from Gunung Telapak Burok.

In conclusion, FM 104.4MHz is the best frequency to be used by commercial radio for Central Pahang, perhaps 300kHz with Gunung Ulu Kali. If THR Gegar use 104.4MHz with at least 2kW (best is 3.5kW) in Bukit Senggora, I think it may be effective to cover Temerloh until Lanchang due to there is no interference with any station from Gunung Telapak Burok.
