A nonode is a type of thermionic valve that has nine active electrodes. The term most commonly applies to a seven-grid vacuum tube, also sometimes called an enneode. An example was the EQ80/UQ80, which was used as an FM quadrature detector. It was developed during the introduction of TV and FM radio and delivered an output voltage large enough to directly drive an end pentode while still allowing for some negative feedback. As most of the grids were tied together, even an 8-pin Rimlock base was sufficient in the case of the EQ40.
In electronics, a vacuum tube, an electron tube, or valve or, colloquially, a tube, is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit. The word was coined by William Whewell at the request of the scientist Michael Faraday from two Greek words: elektron, meaning amber, and hodos, a way.
In telecommunications and signal processing, frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave.
Typically, prior to some process, such as transmission over cable, or recording to phonograph record or tape, the input frequency range most susceptible to noise is boosted. This is referred to as "pre-emphasis" – "pre-" the process the signal will undergo. Later, when the signal is received, or retrieved from recording, the reverse transformation is applied ("de-emphasis") so that the output accurately reproduces the original input. Any noise added by transmission or record/playback, to the frequency range previously boosted, is now attenuated in the de-emphasis stage.
The Ordnance Survey National Grid reference system is a system of geographic grid references used in Great Britain, distinct from latitude and longitude. It is often called British National Grid (BNG).
The pentagrid converter is a type of radio receiving valve with five grids used as the frequency mixer stage of a superheterodyne radio receiver.
The Nikon F80 is an SLR camera manufactured by the Japanese Company Nikon Corporation for prosumers, that is to say amateur photographers with advanced skills.
Classic hits is a radio format which generally includes songs from the top 40 music charts from the mid-1970s to the early 1990s, with music from the 1980s serving as the core of the format. Music that was popularized by MTV in the early 1980s and the nostalgia behind it is a major driver to the format. It is considered the successor to the oldies format, a collection of top 40 songs from the late 1950s through the late 1970s that was once extremely popular in the United States. The term is sometimes incorrectly used as a synonym for the adult hits format, which uses a slightly newer music library stretching from all decades to the present with a major focus on 1990s and 2000s rock and alternative songs. In addition, adult hits stations tend to have larger playlists, playing a given song only a few times per week, compared to the tighter libraries on classic hits stations. For example, KRTH, a classic hits station in Los Angeles, plays power songs up to 30 times a week, which is another differentiator compared to other formats that share songs with classic hits libraries.
Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power. Peak load power plants are dispatched in combination with base load power plants, which supply a dependable and consistent amount of electricity, to meet the minimum demand.

KLCA is a commercial radio station licensed to Tahoe City, California, broadcasting to the Reno, Nevada, and Lake Tahoe areas on 96.5. KLCA airs a Top 40 (CHR) music format branded as "Alice 96-5". The station, part of Tom Quinn's Reno Media Group, operates with a transmitter atop Slide Mountain overlooking Reno, Carson City and Lake Tahoe.
A magic eye tube or tuning indicator, in technical literature called an electron-ray indicator tube, is a vacuum tube which gives a visual indication of the amplitude of an electronic signal, such as an audio output, radio-frequency signal strength, or other functions. The magic eye is a specific type of such a tube with a circular display similar to the EM34 illustrated. Its first broad application was as a tuning indicator in radio receivers, to give an indication of the relative strength of the received radio signal, to show when a radio station was properly tuned in.
WJCS is a religious formatted, non-commercial radio station in Allentown, Pennsylvania, with translator W249CA Bangor. Its slogan is "Your station for inspiration". The station is owned by Beacon Broadcasting Corporation, a not-for-profit corporation. It is affiliated with Moody Broadcast Network, and approximately 85% of its programming originates with Moody.
KHKR is an American radio station simulcast with a format known as 97.7 FM ESPN. Licensed to Washington, Utah, United States, the station is owned by Cherry Creek Radio.
Measurement of life-cycle greenhouse gas emissions involves calculating the global-warming potential of electrical energy sources through life-cycle assessment of each energy source. The findings are presented in units of global warming potential per unit of electrical energy generated by that source. The scale uses the global warming potential unit, the carbon dioxide equivalent, and the unit of electrical energy, the kilowatt hour (kWh). The goal of such assessments is to cover the full life of the source, from material and fuel mining through construction to operation and waste management.
Equalization or equalisation is the process of adjusting the balance between frequency components within an electronic signal. The most well known use of equalization is in sound recording and reproduction but there are many other applications in electronics and telecommunications. The circuit or equipment used to achieve equalization is called an equalizer. These devices strengthen (boost) or weaken (cut) the energy of specific frequency bands or "frequency ranges".
K285EQ is a commercial FM translator radio station licensed to Reno, Nevada, rebroadcasting via the HD2 signal of KLCA/Tahoe City, California, which is licensed by the U.S. Federal Communications Commission (FCC) to broadcast in the HD (hybrid) format.
