      What is a BUC?

      A BUC (Block Upconverter) is a device that converts radio signals from a lower frequency to a higher frequency. BUCs are used in satellite uplink transmissions in order to transfer data from a ground based unit to a satellite in orbit that will then be redirected to another ground based unit in separate location. Likewise,

      How XM Radio Works

      XM radio is one of the two primary satellite radio services in North America. The service is operated by Sirius XM Radio and publishes premium radio content in addition to more than 70 music channels, 39 news, ports, talk, and entertainment choices, 23 play-by-play sports channels, and 21 regional and weather channels. XM radio channels

    • Circuit Simulator

      Circuit Simulator

      A circuit simulator is a computer program that predicts how electronic circuits work. Circuit designs are first entered through the schematic editor, then the simulation engine solves the complex equations that govern circuit behavior. Circuit simulators are especially useful for designing integrated circuits that are impractical to prototype using breadboards. The three types of simulator

    • Business Band

      Business Band

      Business band stands for a series of frequencies in the UHF and VHF two-way radio bands, which are exclusively reserved for businesses to communicate within limited ranges. Of course, not just anyone can use this bandwidth. Anyone that wants to use the business band must first receive a license from the Federal Communications Commission, also

    • Rheostats

      Rheostats

      A rheostat is an electrical component that has an adjustable resistance. It is a type of potentiometer that has two terminals instead of three. The two main types of rheostat are the rotary and slider. The symbol for a rheostat is a resistor symbol with an arrow diagonally across it. Rheostats are used in many

    • Transducer

      Transducer

      The broad definition of a transducer is a device that changes energy from one type into another. However, most transducers change between electricity and another energy type. Transducers also have other names depending on their usage such as probe, detector, pickup, sensor, gauge, and electrode. Chemical Transducers Acidity and alkalinity are measured using a pH

    • Voltage Drop

      Voltage Drop

      Voltage is the measurement for the electrical force between two points that drives the current. More specifically, voltage is the measure of the energy per unit charge that is equal to the electrical potential difference between two measured points. Volts are normally measured by a voltmeter. Voltage drop is the reduction in voltage in an

    • EMF Meters

      EMF Meters

      An EMF meter detects and measures an electromagnetic field. There are many types of EMF meters and they have many uses, including ghost hunting. Most EMF meters are “AC EMF meters” and can only detect the rate of change in an oscillating magnetic field. However, commercial grade EMF meters that can detect specific electromagnetic frequency

    • 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

    • LNB (Low Noise Block)

      LNB (Low Noise Block)

      An LNB (Low Noise Block aka LNC- Low Noise Converter) is used for communications (broadcast) satellite reception. The LNB is usually affixed either in or on the satellite dish. The LNB’s purpose is to utilize the super heterodyne effect and amplify and convert a wide block (band) of frequencies. This helps compensate the signal loss
