For Muin Kamaruddin, one of the most experienced amateur radio users in Lahad Datu, the usage of amateur radio is usually about sharing information with the 100-over members of Public Reliance Corporation Communication Association (PRCC).

These information could include the latest weather, road traffic condition, as well as latest update on any road accidents.

However, at a time of crisis, such as the current conflict in Lahad Datu, Muin is relying on the amateur radio for information that could safe lives.

"We can use the amateur radio to disseminate information on the latest happenings in Lahad Datu. These information could be useful for us to set up a rescue team, and in some cases, allow our members leave a place before any danger arrives," said Muin.

He added that amateur radio is an effective way to disseminate information in sub-urban areas like Lahad Datu, as compared to mobile phones, as amateur radio has a wider frequency.

However, he admitted that amateur radio needs to be cautious of information's authenticity when disseminating them over the channel.

"We also do not want to leak strategic information that could be useful for the enemies. So, we really have to be careful," he added.

Based on a news report last year, there are more than 10,000 amateur radio users in the country, or less than 1 per cent of the population.

The number is deemed low, as compared to our neighbors Thailand and Indonesia -- which has more than 176,000 and 27,815 users. Japan has more than 1 million amateur radio users.

These amateur radio can be purchased for as low as RM800, however, one would need to apply for a license before buying, selling or even using a radio.

Anyone caught using such equipment without a license can be jailed up to three years and fined RM100,000.
