Kool FM Perak frequency (Part 2)

In Ipoh, there is no available frequencies to be used until today. At the previous blog post, titled Kool FM Perak frequency (Part 1), mentioned that 93.3, 93.9 and 94.9 cannot be used due to interference.

Previously I shared my opinion by suggesting to use Bukit Larut 105.7MHz for Kool FM to cover Ipoh and Taiping, but it is not so perfect because not all Ipoh areas can get Kool FM clearly as the signal is blocked by Gunung Kledang and Gunung Bubu, as well as other mountains in Ipoh.

Its sister station Hot FM operates Taiping frequency on FM 90.5MHz in Bukit Larut, actually there is another suggestion to move FM 90.5MHz transmission site to Gunung Kledang for Kool FM, but Hot FM Taiping frequency shall be moved to 105.7MHz by adding new transmitter in Bukit Larut which is originally suggested for Kool FM.

Means Media Prima Malay radio stations frequencies in Perak will be changed like below if the suggestion is applied.

==Media Prima Malay radio in Perak==

FM 104.5MHz: Hot FM Gunung Kledang Ipoh
FM 105.7MHz: Hot FM Bukit Larut Taiping
FM 90.5MHz: Kool FM Gunung Kledang Ipoh (Hot FM will no longer operate in Taiping on 90.5MHz)

If FM 90.5MHz is moved to Gunung Kledang for Kool FM, this will led Central Perak areas are available to receive Kool FM. About its RF analysis, 90.5MHz has no problem as 400kHz separation with Gunung Kledang radio. In addition, Kool FM does not need Taiping frequency as Taiping can receive either 90.2MHz from Bukit Penara or 90.5MHz from Gunung Kledang, meanwhile Hot FM can be listened in Taiping on 105.7MHz.

==RF Analysis Kool FM Ipoh frequency==

90.1MHz: Traxx FM Gunung Kledang
90.5MHz: Kool FM Gunung Kledang
90.9MHz: Nasional FM Gunung Kledang

<400kHz, OK>

90.2MHz: Kool FM Bukit Penara
90.5MHz: Kool FM Gunung Kledang
<300kHz, OK>

== RF analysis Hot FM Taiping new frequency==

105.7MHz: Hot FM Bukit Larut
105.7MHz: Kedah FM Gunung Raya
<0kHz, OK>

105.7MHz: Hot FM Bukit Larut
105.7MHz: Lite FM Gunung Ulu Kali
<0kHz, OK>

105.3MHz: Traxx FM Bukit Larut
105.7MHz: Hot FM Bukit Larut
106.1MHz: Ai FM Bukit Larut
<400kHz, OK>

To use 90.5MHz in Gunung Kledang for Kool FM, current Hot FM 90.5MHz in Bukit Larut transmission equipment shall be removed from the tower, but TX antenna is also needed to be replaced due to Bukit Larut and Gunung Kledang antenna pattern are different. So, this reallocation is needed to get approval from MCMC, and the costs will be very expensive to change the parameters. Installation and modifying parameters also need more time to be performed. 

At the same time, this kind of suggestion also involves costs of changing parameters and equipment. The problem is Hot FM already operates in Taiping on FM 90.5MHz in Bukit Larut since May 2011, Hot FM is earlier than Kool FM actually in terms of its history.

In conclusion, the suggestion is not practical by migrating Hot FM 90.5MHz TX site from Bukit Larut to Gunung Kledang for Kool FM (meanwhile Hot FM Bkt Larut is 105.7MHz after the migration).
