      Round Trip Time

        Round Trip Time, or RTT, also known as “round-trip delay time” is the time it takes for a signal to be sent from a transmitter to a receiver plus the time it takes to verify that the signal has been received; therefore, Round Trip Time is the time it takes for a signal to be

      How to Reset a Kenwood Security Code

      Four digit security codes protect Kenwood car stereos from theft. If a thief steals a Kenwood car stereo, he/she will not be able to use the stereo until the secret four digit security code is entered. Unfortunately, many legitimate owners are also locked out of their Kenwood car stereos due to these security codes. This

    • Trunking

      Trunking

      Traditional radio equipment works because all parties involved in the communication agree on what frequencies they will utilize. Traditional radio scanners work by scanning for and then listening to those frequencies. Trunking radios, on the other hand, constantly renegotiate the frequencies utilized for the conversation. This allows for more efficient utilization of limited frequencies because

    • Low Earth Orbit

      Low Earth Orbit

      Low Earth Orbit (LEO) refers to a satellite which orbits the earth at altitudes between (very roughly) 200 miles and 930 miles. Low Earth Orbit satellites must travel very quickly to resist the pull of gravity — approximately 17,000 miles per hour. Because of this, Lowe Earth Orbit satellies can orbit the planet in as

    • IR Blaster

      IR Blaster

      An IR blaster (infrared blaster) is a device that emulates an infrared remote control. IR blasters are used in situations where one device controls another. For example, it can be connected to a computer in order to control virtually every other infrared device in the room from that computer. IR blasters are usually small and

    • Yagi Antenna

      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

    • Pulse Width Modulation

      Pulse Width Modulation

      Pulse Width Modulation, abbreviated as PWM, is a method of transmitting information on a series of pulses. The data that is being transmitted is encoded on the width of these pulses to control the amount of power being sent to a load. In other words, pulse width modulation is a modulation technique for generating variable

    • Linear LNB

      Linear LNB

      LNB stands for low noise blocker and it is essentially an amplifier on the end of your small satellite TV dish or communications dish. The “Linear” portion of Linear LNB stands for the characteristics of the radio waves that are transmitted via the satellite in space to your dish (LNB). Two Types of Polarization Circular

    • Thyristor

      Thyristor

      A thyristor is a solid state semiconductor device that consists of four alternating layers of N-type and P-type material. Many sources consider thyristors to be the same as Silicon Controlled Rectifiers (SCRs). In some cases they are defined as a large group of devices – the eligibility criterion being that the device should consist of

    • UHF (Ultra High Frequency)

      UHF (Ultra High Frequency)

      UHF is an acronym for a band of radio frequencies often used to broadcast television signals. Mobile phones and satellite radio also use UHF signals. The letters ‘UHF’ stand for: Ultra High Frequency. UHF Frequencies Any radio frequency between 300 MegaHertz (MHz) and 3,000 MHz (or 3 GigaHertz) is considered to be in the UHF
