      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

    • Breadboard


      A breadboard is a thin rectangular piece of insulating material used to hold electronic components when making circuit prototypes. They have many rows and columns of conductive points for inserting component terminals and jumper wires. The original breadboards were just wooden boards, presumably used to cut bread on, but the modern versions have plastic cases

    • GMRS (General Mobile Radio Service)

      GMRS (General Mobile Radio Service)

      GMRS (General Mobile Radio Service) is a licensed radio service. GMRS consists of 16 UHF channels on FM, plus 7 channels that are shared with FRS. The maximum allowable power for a GMRS radio is 50 watts. The GMRS channels which are shared with FRS are limited to 5 watts of power. The use of

    • Circulators


      A circulator is a box-shaped ferrite device that has three or four ports and allows energy from one port to transfer to the next port in line. Circulators are usually used with radio signals but can also be used with microwaves, light, and other electromagnetic waves. This means that a radio signal that is being

    • FCC ID

      FCC ID

      FCC ID stands for Federal Communications Commission Identification. An FCC ID is the number found in all computer hardware components. FCC ID numbers, usually found on the circuit boards, are helpful in finding information about the manufacturers of the hardware devices. An FCC ID has 2 elements. The first is a three-character Grantee Code which

    • Crosstalk


      Crosstalk is a form of interference caused by signals in nearby conductors. The most common example is hearing an unwanted conversation on the telephone. Crosstalk can also occur in radios, televisions, networking equipment, and even electric guitars. Causes of Crosstalk Crosstalk is caused by coupling, the transfer of electrical energy between conductors. The three main

    • FSK (Frequency Shift Keying)

      FSK (Frequency Shift Keying)

      FSK (Frequency Shift Keying) is also known as frequency shift modulation and frequency shift signaling. Frequency Shift Keying is a data signal converted into a specific frequency or tone in order to transmit it over wire, cable, optical fiber or wireless media to a destination point. The history of FSK dates back to the early

    • MS Connectors

      MS Connectors

      MIL-C-5015, now known popularly as MS connectors, are multi-pin, highly durable connectors that were originally invented for use in military applications. They have a variety of features that makes them easy to use for nearly any application and are often found in a variety of advanced, high power, heavy duty devices in the industrial world.

    • S Band

      S Band

      S band is a frequency range from approximately 2 to 4 GHz. S band is used for Digital Audio Radio Satellite (DARS) satellite radio systems such as Sirius XM Satellite Radio.  Sirius XM uses frequencies between 2,320.00 and 2,332.50 MHz, and also between 2,332.50 and 2,345.00 MHz. S band is also used by many weather,

    • Types of Projector Lamps

      Types of Projector Lamps

      A projector lamp is used to transfer an image from a multimedia projector onto a larger screen. Earlier halogen bulbs were used for many years for projection purposes, but were discontinued as halogen produced a yellow tone on the images. A projector lamp relies on an intense light bulb, called a metal halide bulb, to
