The YASME Foundation was formed to fund Danny Weil’s (VP2VB) DXpeditions on his sailboat YASME (the name is Japanese meaning to make tranquil). Danny was one of the first to travel to more than one location to operate – often solo in a sailboat and lugging hundreds of pounds of radio equipment – specifically to provide DXers with a “new one.” … From YASME.org
Also called a “beam antenna”, or “parasitic array”, the Yagi is very widely used as a high-gain antenna on the HF, VHF and UHF bands. It has moderate to high gain which depends on the number of elements used, typically limited to about 20 dBi,linear polarization, unidirectional (end-fire) beam pattern with high front-to-back ratio of up to 20 db. and is lightweight, inexpensive and simple to construct. The bandwidth of a Yagi antenna, the frequency range over which it has high gain, is narrow, a few percent of the center frequency, and decreases with increasing gain, so it is often used in fixed-frequency applications. The largest and best-known use is as rooftop terrestrial television antennas, but it is also used for point-to-point fixed communication links, in radar antennas,[ and for long distance shortwave communication by shortwave broadcasting stations and radio armatures.
The Rhombic Antenna is an equilateral parallelogram shaped antenna. Generally, it has two opposite acute angles. The tilt angle, θ is approximately equal to 90° minus the angle of major lobe. Rhombic antenna works under the principle of travelling wave radiator. It is arranged in the form of a rhombus or diamond shape and suspended horizontally above the surface of the earth.
Chew the fat dates back to the first time in print and that is 1885, from a book written by J Brunlees Patterson called “Life in the Ranks of the British Army in India”. In his book chew the fat was referencing army soldiers gossiping amongst themselves and the junior officers to keep from being bored. This may not be its beginning but it is for its use associated with conversation, the term does go back to when a fat soaked rag end was bitten off to be wrapped around a musket ball while loading.
Chew the rag, although its original origin is unknown was first in print in the 1875 printing of “The Random House Historical Printing of American Slang”, and then in 1885 appeared in the same sentence in a book “Life in the Ranks of the British Army in India”.
Some speculate that the term relates too cloth and ladies sewing circles or women gossiping while quilting.
The IARU is an international organization that was formed in Paris France in 1925 and is not made up of individual amateur radio operators, instead it is made up of amateur radio societies, such as the ARRL. The IARU is broken down to 3 regions, for more about the IARU…. Click Here
At age 8, Horowitz achieved distinction as the world’s youngest amateur radio operator. He went on to study physics at Harvard University (B.A., 1965; M.A., 1967; Ph.D., 1970), where he has also spent all of his subsequent career. His early work was on scanning microscopy (using both protons and X-rays). Horowitz has also conducted astrophysical research on pulsars and investigations in biophysics. His interest in practical electronics has led to a handful of inventions, including an automated voting machine and an acoustic mechanism for landmine detection. Since 1974 he has taught a practical course in electronics whose lecture notes became one of the best known textbooks in the field: The Art of Electronics (coauthored with Winfield Hill).
