      Ham Radio Software

      Ham Radio Software, also known as Amateur Radio Software, refers to computer programs designed exclusively for ham radio equipment. Once thought to be a means of communication between radio enthusiasts, ham radio now coexists with software including data and contest loggers, log books, Morse code tutors, and antenna design aids. In the 21st century there

      Photodetectors

      A photodetector is a device that imprints the image of an object or scene onto a material. Photodetectors are made in various ways and can be used for different purposes. Most photodetectors fall into the phototube, thermal detector, or camera category. These photodetectors are used for communication, navigation, and record keeping. Types of Photodetectors Phototube

    • What is a Multivibrator?

      What is a Multivibrator?

      A multivibrator is an electronic circuit that rapidly switches because of positive feedback between multiple states. The switch’s output is harmonic. Three types of multivibrator circuits are used in industry today: astable, monostable, and bistaple. Types of Multivibrators The three multivibrator types are: Astable Multivibrator – The circuit is not considered stable in either 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

    • LNB Tester

      LNB Tester

      Before you ask what an LNB tester is, you should know what an LNB is. An LNB is the receiving end of a satellite dish. LNB stands for low noise blocker; it is a device that essentially does what it says. It blocks low noise (frequencies) in order to receive higher frequencies in which satellite

    • 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

      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
