The particular person accountable for all features and correct operation of a radio station. The individual at a broadcasting station accountable for proper and authorized operation of a station and maintenance of all required records. A station that all the time operates from a constant, specified land location. The physical location from which a radio stations features (setting frequency, turning the station off and on, and so forth.) are controlled. When two or extra packet radio stations concurrently attempt to transmit on the same frequency. The quantity of frequency space occupied by a radio signal. A receiver circuit that modify the amount of amplification given to a acquired sign in order that the amount from the speaker stays relatively fixed. The constant output of a radio transmitter that may be periodically interrupted to send messages by Morse code. AMTOR: Acronym for "newbie teleprinting over radio," a mode that uses FSK to send messages containing error detection capabilities and the ability request retransmission of lacking or corrupted data.

ANARC: Acronym for "Association of North American Radio Clubs," an affiliation of radio listener clubs in the United States and Canada. ARRL: Acronym for "American Radio Relay League," the nationwide affiliation for ham radio operators in the United States. ASCII: Acronym for "American commonplace code for data interchange," a technique of representing upper and decrease letters in addition to numbers and particular symbols. How well a receiver responds to weak signals, measured in microvolts (mV); the decrease the variety of microvolts indicated, the more delicate the receiver. Just like exalted provider reception, but the replacement provider tuning and tracking is done mechanically by the receiver. A tuning methodology in transmitters and receivers which makes use of a few piezoelectric crystals to generate a wide range of frequencies. A frequency vary put aside for international ham radio stations to transmit in whereas ham stations within the United States and Canada do not; American and Canadian stations name foreign stations on frequencies outdoors the window. A method of proscribing access to a repeater station to stations that begin their transmission with a particular sequence of tones. Spoken at the end of a transmission to indicate to the opposite station that it's their flip to transmit.

The frequency on which a radio transmission takes place, or the input and output frequency pair utilized by a repeater station. The decrease the angle, the larger distance the radio signal will journey through ionospheric refraction. Placing a loading coil at the middle of an antenna with the intention to lower the antennas resonant frequency. A modulation methodology by which the timing, amplitude, medium voltage overhead cable and/or spacing of pulses of a transmitters carrier are diversified with a purpose to convey data. PM: Abbreviation for phase modulation. PLL: abbreviation for part locked loop. CW: Abbreviation for continuous wave. The frequency at or near the MUF at which the utmost sky wave propagation range is obtained. A circuit that tunes a receivers signal amplifying circuitry for maximum sensitivity on a desired frequency range. A system put in between a receiver or transmitter and the antenna to match the radio impedance to the antenna impedance for maximum energy switch.

A circuit that eliminates undesirable audio frequencies from the audio output of a receiver. A modulation technique that varies the ability output of a transmitter in accordance with the variations within the modulating audio signal. A modulation technique that varies the service frequency of a transmitter in accordance with the variations in the energy of the modulating audio signal. That is used after a frequency to indicate that it varies barely. A gaggle of stations that meet on a specified frequency at a certain time. A non-governmental group to customers in order to stop interference, especially for repeater stations. A bunch of letters and numbers used to establish a station and the nation authorizing its operation. 1) When a station ends its operations and shuts down; 2) When a frequency can not assist propagation to a desired station or location. QTH: Radiotelegraph abbreviation for a stations location.
