Receiver (radio)
Types of radios

Amateur radio

Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications.

See Communications receiver and Amateur radio

Automatic gain control

Automatic gain control (AGC) is a closed-loop feedback regulating circuit in an amplifier or chain of amplifiers, the purpose of which is to maintain a suitable signal amplitude at its output, despite variation of the signal amplitude at the input.

See Communications receiver and Automatic gain control

Bandspread

In a radio receiver, a bandspread control is a secondary tuning control that allows accurate tuning of closely spaced frequencies of a radio band.

See Communications receiver and Bandspread

Bandwidth (signal processing)

Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies.

See Communications receiver and Bandwidth (signal processing)

Beat frequency oscillator

In a radio receiver, a beat frequency oscillator or BFO is a dedicated oscillator used to create an audio frequency signal from Morse code radiotelegraphy (CW) transmissions to make them audible.

See Communications receiver and Beat frequency oscillator

In amateur radio and computing, a boat anchor or boatanchor is something obsolete, useless, and cumbersome – so-called because metaphorically its only productive use is to be thrown into the water as a boat mooring.

See Communications receiver and Boat anchor (metaphor)

Electromagnetic shielding

In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials.

See Communications receiver and Electromagnetic shielding

In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier wave is shifted as an intermediate step in transmission or reception.

See Communications receiver and Intermediate frequency

Intermodulation

Intermodulation (IM) or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies, caused by nonlinearities or time variance in a system.

See Communications receiver and Intermodulation

List of communications receivers

This is a list of rack-mount or tabletop communications receivers that include short wave frequencies. Communications receiver and list of communications receivers are receiver (radio) and types of radios.

Marconi Company

The Marconi Company was a British telecommunications and engineering company that did business under that name from 1963 to 1987.

See Communications receiver and Marconi Company

Morse code

Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs.

See Communications receiver and Morse code

Plessey

The Plessey Company plc was a British electronics, defence and telecommunications company.

See Communications receiver and Plessey

Product detector

A product detector is a type of demodulator used for AM and SSB signals.

See Communications receiver and Product detector

Q multiplier

In electronics, a Q multiplier is a circuit added to a radio receiver to improve its selectivity and sensitivity.

See Communications receiver and Q multiplier

R-390A

The R-390A /URR is a general coverage HF radio communications receiver designed by Collins Radio Company for the United States Armed Forces.

See Communications receiver and R-390A

Racal

Racal Electronics plc was a British electronics company that was founded in 1950.

See Communications receiver and Racal

Radio broadcasting

Radio broadcasting is the broadcasting of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience.

See Communications receiver and Radio broadcasting

Radio frequency

Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around.

See Communications receiver and Radio frequency

Radio receiver

In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. Communications receiver and radio receiver are receiver (radio).

See Communications receiver and Radio receiver

Radio scanner

A scanner (also referred to as a radio scanner) is a radio receiver that can automatically tune, or scan, two or more discrete frequencies, stopping when it finds a signal on one of them and then continuing to scan other frequencies when the initial transmission ceases. Communications receiver and radio scanner are receiver (radio).

See Communications receiver and Radio scanner

RCA

The RCA Corporation was a major American electronics company, which was founded in 1919 as the Radio Corporation of America.

See Communications receiver and RCA

Rockwell Collins

Rockwell Collins, Inc. was a multinational corporation headquartered in Cedar Rapids, Iowa, providing avionics and information technology systems and services to government agencies and aircraft manufacturers.

Rohde & Schwarz

Rohde & Schwarz GmbH & Co KG is an international electronics group specializing in the fields of electronic test equipment, broadcast & media, cybersecurity, radiomonitoring and radiolocation, and radiocommunication.

S meter

An S meter (signal strength meter) is an indicator often provided on communications receivers, such as amateur radio or shortwave broadcast receivers. Communications receiver and s meter are receiver (radio).

See Communications receiver and S meter

Shortwave listening

Shortwave listening, or SWLing, is the hobby of listening to shortwave radio broadcasts located on frequencies between 1700 kHz and 30 MHz Listeners range from casual users seeking international news and entertainment programming, to hobbyists immersed in the technical aspects of long-distance radio reception and sending and collecting official confirmations (QSL cards) that document their reception of remote broadcasts (DXing).

See Communications receiver and Shortwave listening

Shortwave radio

Shortwave radio is radio transmission using radio frequencies in the shortwave bands (SW).

See Communications receiver and Shortwave radio

Shortwave radio receiver

A shortwave radio receiver is a radio receiver that can receive one or more shortwave bands, between 1.6 and 30 MHz. Communications receiver and shortwave radio receiver are receiver (radio) and types of radios.

See Communications receiver and Shortwave radio receiver

Single-sideband modulation

In radio communications, single-sideband modulation (SSB) or single-sideband suppressed-carrier modulation (SSB-SC) is a type of modulation used to transmit information, such as an audio signal, by radio waves.

See Communications receiver and Single-sideband modulation

Superheterodyne receiver

A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency. Communications receiver and superheterodyne receiver are receiver (radio).

See Communications receiver and Superheterodyne receiver

Traffic analysis

Traffic analysis is the process of intercepting and examining messages in order to deduce information from patterns in communication.

See Communications receiver and Traffic analysis

Transmitter

In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna with the purpose of signal transmission up to a radio receiver.

See Communications receiver and Transmitter

Two-way radio

A two-way radio is a radio transceiver (a radio that can both transmit and receive radio waves), which is used for bidirectional person-to-person voice communication with other users with similar radios, in contrast to a broadcast receiver, which only receives transmissions.

See Communications receiver and Two-way radio

Wadley loop

The "Wadley-drift-canceling-loop", also known as a "Wadley loop", is a system of two oscillators, a frequency synthesizer, and two frequency mixers in the radio-frequency signal path.
