      Modulation

      Modulation is the process of varying some characteristic of a periodic wave with external signals. Modulation is utilized to send an information bearing signal over long distances. Radio communication superimposes this information bearing signal onto a carrier signal. These high frequency carrier signals can be transmitted over the air easily and are capable of traveling

    • Radar Jammer

      Radar Jammer

      A radar jammer is a piece of equipment used to scramble nearby radar signals. Radar jammers are often used by drivers to jam the signals coming out from police speed detectors. The radar jammer is very similar to the Power Drainer and is the size of a small box. Radar Jamming as a Crime There

    • FRS (Family Radio Service)

      FRS (Family Radio Service)

      FRS (Family Radio Service) is an unlicensed service. FRS (Family Radio Service) consists of 14 UHF channels on FM. FRS Channel 1 is unofficially used as a common call channel. FRS (Family Radio Service) shares channels 1 through 7 with GMRS, and many FRS radios are also GMRS radios. The maximum allowable power for a

    • Internet Repeater

      Internet Repeater

      An Internet repeater is a device that allows amateur radio operators to communicate with each other over the Internet, much like how VoIP software allows telephone operators to communicate with each other over the Internet. Internet repeaters should not be confused with wireless repeaters, which allow users to extend the range of a wireless network.

    • Attic Antennas

      Attic Antennas

      An attic antenna is one that is mounted inside of an attic in order to provide maximum range as well as protection from rain, snow, sun, wind, and animals. Attic antennas are rather common and provide quality reception for those who live in rural areas, away from most radio transmitters. While attic antennas do not

    • Amplitude Modulation

      Amplitude Modulation

      Amplitude modulation is a type of modulation where the carrier signal’s amplitude is varied in accordance with the information bearing signal. The amplitude modulated signal’s envelope or boundary embeds the information bearing signal. The total power of the transmitted signal varies with the modulating signal, whereas the carrier power remains constant. A nonlinear device combines

      Yagi Antenna

      Yagi Antennas are one of the most well-known directional antennas in use throughout the world and are used for communications in the medium range of three to five miles between two points. They can also be used as a bridge antenna to connect clients to an access point. The original inventors of the antenna design

      Military Alphabet

      The military alphabet, or more properly the phonetic alphabet, exists in innumerable variants. If any military alphabet can be viewed as the most correct, it is the current NATO standard military alphabet. However, even with the NATO standard military alphabet, various member nations use numerous spelling variations. This version of the military alphabet is also

      BNC Connector

      More properly known as the Bayonet Neill-Concelman connector, the BNC connector is one of several radio frequency connectors on the market today. The name of the connector is derived from a combination of two things: 1) the connecting technology employed; and 2) the names of the two inventors of the device. Paul Neill of Bell
