SWR or standing wave ratio is the ratio of the amplitude of a partial standing wave at an antinode (maximum) to the amplitude at an adjacent node (minimum), in an electrical transmission line. The SWR ...

Maximum transmission efficiency occurs when the load impedance matches the generator impedance. Engineers do this to eliminate standing waves, which can severely damage equipment. Transmission lines ...

The project was based on a PIC16F877A microcontroller for the basic purpose of encouraging radio amateurs to build their own SWR meter at a very cheap price compared to high-priced ready made. Two ...

Even with the rise of cellular communications, radio networks remain an important part of business communications, especially for small businesses such as trucking and security companies. Proper ...
