ABOUT KEDAH HISTORY

Recorded history shows that in the 5th century AD, traders plying the east-west trade route stopped at the port of Kuala Muda, using Gunung Jerai, Kedah's highest peak, as a navigational point.

The ruins of ancient Candi (temples) in the Bujang Valley show that a Hindu-Buddhist civilization existed here and may have been one of the first places to have come into contact with Indian traders. How important this kingdom was, is still being researched as more artifacts are unearthed.

During the 7th and 8th centuries, Kedah paid tribute to the Sumatran Srivijaya Empire. After the decline of the empire, it became a vassal state to the Thais until the 15th Century when the rise of Malacca led to the Islamization of the area. Kedah faced Portuguese and Achehnese attacks in the 17th century, but it again fell into Thai hands in 1821.

The Thais handed Kedah over to the British in 1909, and after the Japanese occupation, it became one of the states of the Malayan Union and subsequently the Federation of Malaya in 1948.

Stellar Nursery in the Rosette Nebula

This image from the European Space Agency's Herschel Space Observatory shows the cloud associated with the Rosette Nebula, a stellar nursery about 5,000 light-years from Earth in the Monoceros, or Unicorn, constellation. Herschel collects the infrared light given out by dust. The bright smudges are dusty cocoons containing massive embryonic stars, which will grow up to 10 times the mass of our sun. The small spots near the center of the image are lower mass stellar embryos. The Rosette Nebula itself, and its massive cluster of stars, is located to the right of the picture. This image is a three-color composite showing infrared wavelengths of 70 microns (blue), 160 microns (green), and 250 microns (red). It was made with observations from Herschel's Photoconductor Array Camera and Spectrometer and the Spectral and Photometric Imaging Receiver instruments.Herschel is an ESA cornerstone mission, with science instruments provided by consortia of European institutes and with participation by NASA. A media day celebrating the release of the first results from ESA’s Herschel infrared space telescope will take place on May 6, 2010, at Space Expo, at the European Space Research and Technology Centre (ESTEC), Noordwijk, The Netherlands. Doors open at 11:30 CEST. The media day is organized in connection with the Herschel First Results Symposium taking place this week at ESTEC and the theme is Revealing the Hidden Side of Star Formation. For more information on the day's activities, see the press release.For more information on this image, visit ESA's Herschel Program site.

Double Black Holes

This image from the Chandra X-ray Observatory shows the central region of the starburst galaxy M82 and contains two bright X-ray sources of special interest. New studies with Chandra and ESA's XMM-Newton show that these two sources may be intermediate-mass black holes, with masses in between those of the stellar-mass and supermassive variety. These "survivor" black holes avoided falling into the center of the galaxy and could be examples of the seeds required for the growth of supermassive black holes in galaxies, including the one in the Milky Way. This is the first case where good evidence for more than one mid-sized black hole exists in a single galaxy. The evidence comes from how their X-ray emission varies over time and analysis of their X-ray brightness and spectra, i.e., the distribution of X-rays with energy. These results are interesting because they may help address the mystery of how supermassive black holes in the centers of galaxies form. M82 is located about 12 million light years from Earth and is the nearest place to us where the conditions are similar to those in the early Universe, with lots of stars forming. Multiple observations of M82 have been made with Chandra beginning soon after launch. The Chandra data shown here were not used in the new research because the X-ray sources are so bright that some distortion is introduced into the X-ray spectra. To combat this, the pointing of Chandra is changed so that images of the sources are deliberately blurred, producing fewer counts in each pixel.

Ring of Fire

This new image from the Solar Dynamics Observatory’s Atmospheric Imaging Assembly (AIA) shows in great detail a solar prominence taken from a March 30, 2010 eruption. The twisting motion of the material is the most noticeable feature. Launched on Feb. 11, 2010, SDO is the most advanced spacecraft ever designed to study the sun. During its five-year mission, it will examine the sun's magnetic field and also provide a better understanding of the role the sun plays in Earth's atmospheric chemistry and climate. Since launch, engineers have been conducting testing and verification of the spacecraft’s components. Now fully operational, SDO will provide images with clarity 10 times better than high-definition television and will return more comprehensive science data faster than any other solar observing spacecraft.

ABOUT AMATEUR RADIO

Amateur radio service is defined in the Communication and Multimedia (Spectrum) Regulations 2000 as a radiocommunications service (covering both terrestrial and satellite) in which a station is used for the purpose of self traning, intercommunication and technical investigations carried out by authorized persons who are interested in radio technique solely with a personal aim and without any pecuniary interest.

AMATEUR RADIO OPERATOR'S CERTIFICATE

Regulation 27(1) of the Communications and Multimedia (Technical Standards) Regulations 2000 states that no person shall undertake or conduct any activity in designated skil area unless that person is certified. Amateur radio operator has been gazetted as a designated skill area category under the regulation, hence to operate an amateur radio station a person needs to have an appropriate proficiency and skill i.e. certified in this area.

INTERFERENCE

Please ensure that the radio transmision does not cause interference to any other radio services. Regulation 15(1) of the Communications and Multemedia (Technical Standards) Regulations 2000 states that no person shall intentionally design, install, operate, maintain or modify any communications equipment in a manner is likely to cause interference with, impairment, mulfunction of, or harm to any communications equipment or any other equipment.

Regulation 15(2) of the regulation denotes that a person who contravenes this regulation commits an offence and shall, on conviction, be liable to a fine not exceeding three hundred thousand ringgit (RM 300,000.00) or to imprisonment for a term of not exceeding three years or to both.

To eliminate the potential of interferences, the following procedures must be followed strictly:-

a) Ensure that suffient equipment, tools and test gear is available and can used to monitor and verify that your transmission does not cause any interference to other radio services.

b) You must responsible if your amateur radio is found to be the caused of interference. Immediate remedy action must be taken to rectify the problems in case of interference.

c) Ensure that the transmission do not exceed the level of over deviation.

d) Ensure that the radiated energy is always within the narrowest posible frequency bands for any class of emission in use.

e) The radiation of harmonics and spurious emissions should be suppressed to minimize interference.

Historical Description of Amateur Radio: From the Encyclopedia Britannica:-

Interest in amateur radio arose around the turn of the century, shortly after the Italian inventor Guglielmo Marconi successfully sent the first transatlantic wireless signal in 1901. The interference of amateur broadcasts with commercial and military transmissions led to the institution of government control in 1911. After World War I, amateurs became active in radio experimentation, contributing to developments in long-distance broadcasting and becoming the first radio operators successfully to exploit the upper medium-frequency and lower high-frequency radio bands. Over the years, amateur radio operators have also provided emergency communications during forest fires, floods, hurricanes, and other disasters. They serve as an important link between stricken communities and the outside world until normal communications are reestablished.Amateur radio operators in the United States are subject to international and federal regulations. There are five classes of licenses. Competence in the use of the International Morse Code and a knowledge of radio theory and regulation are required to obtain the advanced-level licenses. Amateur radio is allocated frequencies at the extreme high-frequency end of the medium-wave band, five groups of frequencies in the shortwave band, two groups in the veryhigh-frequency band, three in the ultrahigh-frequency band, and seven in the superhigh-frequency band for telegraphic and telephonic communication using amplitude and frequency modulation. There are restrictions on the power of the transmitters, and certain of the frequencies must be shared with due regard for the needs of other users.
