Do you know Series - 6

Do you know that:

Upon switching on your amateur radio, you are required to listen on the frequency to ensure that it is free, before you can operate your radio?

To join the conversation if its not free, you are to give them your callsign during the pause period, and not use the word "break" or "contact"?

When operating through a repeater, the order of priority should be as tabulated below:

First - Stations relaying/transmitting emergency or distress message

Second - Stations using low power or handsets

Third - Stations that are Mobile

Fourth - Stations that are at Base or high powered handsets

Prohibited Transmissions

Communications relating to anti government/religion/politics/business and racial issues/other issues that are sensitive to the people of Malaysia.

No transmission of music; communications intended to facilitate a criminal act; messages in codes or ciphers intended to obscure the meaning thereof; messages containing profane, offensive, obscene or indecent words of any language.

No engagement in any form of broadcasting for sending news, advertisements for percuniary reward for and on behalf of a third party.

You should not use the amateur radio apparatus such as to disrupt the usage of the amateur radio frequency or any other acts which can cause interference with other services.

You should not retransmit programs or signals from any types of radio station other than an amateur station, except weather forecast information intended for use by the general public and originated from a Malaysian Government station.

Lightning Strikes to Jalopies

What happens when lightning strikes a vehicle? The answer, gleaned from anecdotal observations, is all the way from "nothing" to "Wow! What a mess. . . my car is a disaster."

Electrically speaking, at lightning's higher frequencies, currents are carried mostly on the outside of conducting objects. A thick copper wire or a hollow-wall metal pipe will carry most of the lightning on outer surfaces. This phenomenon is called Skin Effect. The same holds true for lightning when it strikes metal vehicles: the outer surface carries most of the electricity. The persons inside this steel box can be likened to protected by a partial Faraday Cage.

But, consistent with lightning's capricious nature, situations alter results. Is the car dry or wet? If the car is made of fiberglass (a poor conductor) or a convertible, Skin Effect principles may not work. [Corvette and Saturn owners please note.]

The complete article is available at :

The website has some good photos of Jalopies after being struck by lightning!

Our friends have managed to get a Venue for us to conduct the
RAE Review session on the 28May05 at Proton Edar Training Room,
Lot 203 Jalan Ampang. The Venue is within a "stone's throw" from
the Ampang/Outer Middle Ring Road Intersection. It has also been highlighted
that the Proton Edar Showroom is very close to Land Rover
and Volvo Showroom.

Amateur Radio

Things you need to know about

What is Amateur Radio?

Amateur Radio, also affectionately known as "ham radio", is the hobby of constructing, experimenting and communicating via radio.
Amateur radio fans communicate with each other around the world via a set number of radio frequencies.

When was Amateur Radio started?

Amateur Radio is as old as radio itself. In 1912, the American Congress passed the first laws regulating radio transmissions in the US. By 1914, amateur experimenters were communicating nationwide and setting up a system to relay messages from coast to coast. In Malaysia, amateur radio was the precurser to commercial radio broadcast.

What can I do with Amateur Radio?

Unlike other communications technologies, Amateur Radio allows you to communicate from virtually anywhere! You can communicate from the top of a mountain; your home or behind the wheel of your car. You can take the radio wherever you go. In times of disaster (such as the recent Tsunami), when regular communncations channels fail, "hams" can swing into action assisting emergency communication efforts and work with public service agencies . Amateur Radio operators can talk to Shuttle astronauts or bounce signals off the moon for wider area coverage. Amateur Radio operators can also transmit images and files digitally. Know of any other hobby with so much to offer?

I don't have a lot of time. Can I still enjoy the hobby?

You bet! The beauty of operating an Amateur Radio is that it can fit the time, space and budget that you decide is right for you. Its got that low stress, high fun ratio that so many busy people seek in their off-hours. It can also be great family fun or a solitary pleasure.

What will this cost me?

A basic new hand-held radio can cost about the same as an inexpensive 19-inch TV. A new tabletop multi-band unit can cost about the same as a PC. Materials to get you started are relatively inexpensive and the exam fee you'll pay when you're ready to test, is nominal. Alternatively, if you are inclined to experiment, as most Amateur Radio Operators are, you can build your own Amateur Radio Unit.

Who can help me out?

Amateur Radio clubs are located all over the country and are eager to help newcomers. Many of these clubs have their own websites, which contain a large amount of information on the hobby. One example of such a site is the one hosted by the Malaysian Amateur Radio Transmitters' Soceity ("MARTS") at (now web site is inactive), or unoffical websites such as
and this site.

How do I become an Amateur Radio operator

Only certified Amateur Radio operators can operate Amateur Radio equipment. In order to get a certificate, you should be above 14 years old, a Malaysian Citizen and have passed any of the following:

  • Radio theory and understanding of Radio Regulations for Class B Certificate; or
  • Radio theory, understanding of Radio Regulations and Morse Code Test for Class A Cetificate.

Are there any fees payable?

Yes, you have to pay an annual fee for the Certificate. The fee for Class A Certificate is RM36, while for Class B Cerificate is RM24.
