As today, RTM Labuan FM currently broadcasts with 2 frequencies, notably 103.7MHz from RTM Labuan and 89.4MHz from Bukit Timbalai to cover entire Labuan Island, both frequencies are using 0.1kW transmitter power.
Look at its history, RTM Labuan FM was launched in 1986, it operated on the frequency 102.9MHz at RTM Labuan until 1994 before changing to 103.7MHz. In the year of 2000, RTM Labuan FM launched 89.4MHz when Bukit Timbalai transmitter was established.
In my opinion, it is a duplicate transmission of Labuan FM in Labuan Island because both 103.7MHz and 89.4MHz can be tuned clearly elsewhere in Labuan.
103.7MHz from RTM Labuan acts as transponder to send studio feed to Bukit Timbalai transmitter, meanwhile 89.4MHz Bukit Timbalai receives the feed from RTM Labuan and transmit the signal to entire island.
To integrate both frequencies into 1 frequency, RTM Labuan FM 103.7MHz can move to Bukit Timbalai transmitter and increase the transmitter power from 0.1kW to 0.5kW, so RTM Labuan FM can cover whole island with 1 frequency only, but RTM Labuan FM has to install studio-transmitter-link (STL) system, so it can send studio feed to Bukit Timbalai via STL microwave signal, same as Melaka FM 102.3MHz, sending studio signal from RTM Melaka to Gunung Ledang via STL system.
If RTM Labuan FM 103.7MHz moves to Bukit Timbalai, so 89.4MHz can be abolished permanently in Labuan because it is already sufficient to cover entire Labuan Island via Bukit Timbalai transmitter.
==RTM Labuan frequency transmission==
* Current: 103.7MHz RTM Labuan (0.1kW) & 89.4MHz Bukit Timbalai (0.1kW)
* Suggestion: 103.7MHz Bukit Timbalai (0.5kW)
==Result after suggestion==
* 89.4MHz Bukit Timbalai transmission is abolished by changing frequency to 103.7MHz
* RTM Labuan transmitter is no longer in operation on FM radio transmission as transponder, replaced by STL system to send studio feed to Bukit Timbalai.
