Early Sea Snarks featured an unclad one-piece injection-molded EPS hull and the hull weighed approximately 30 lbs. Later versions, marketed s the Sunflower, Super Snark and Super Sea Snark featured a vacuum formed layer of ABS (later ASA) [7] bonded over the EPS hull for a hull weight of 43 lbs. Snark Products patented the cladding process, which eliminated the possibility of voids within the ...
The Northrop SM-62 Snark is an early-model intercontinental range ground-launched cruise missile that could carry a W39 thermonuclear warhead. Though the Snark was in training by the United States Air Force 's Strategic Air Command from 1958 through 1961, it was only deployed as an operational missile for less than a year during 1961.
A television tuner or TV tuner, also called a TV receiver, is a component or subsystem that converts analog television or digital television transmissions into audio and video signals which can be further processed to produce sound and a picture. [29] [30] [31] A TV tuner must filter out unwanted signals and have a high signal-to-noise ratio. [32]
EM34 tuning eye EM84 tuning indicator. A magic eye tube or tuning indicator, in technical literature called an electron-ray indicator tube, [1] 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.

English: The image gives six circuit diagrams (schematics) for balanced line antenna tuners of the tuned-transformer type, discussed in the Wikipedia article "Antenna Tuner" or "ATU". It is an edited version of the original by JNRSTANLEY uploaded 2014-10-15.
Up to 32 tuners can be allocated a different frequency in the IF range and for each, the SCR LNB downconverts the corresponding individually requested transponder. [ 9 ] Most SCR LNBs also include either a legacy mode of operation or a separate legacy output which provides the received spectrum block-downconverted to the whole IF range in the ...
A machine head (also referred to as a tuning machine, tuner, or gear head) is a geared apparatus for tuning stringed musical instruments by adjusting string tension. Machine heads are used on mandolins, guitars, double basses and others, and are usually located on the instrument's headstock .
The schematic diagram shows a typical TRF receiver. This particular example uses six triodes. It has two radio frequency amplifier stages, one grid-leak detector/amplifier and three class ‘A’ audio amplifier stages. There are 3 tuned circuits T1-C1, T2-C2, and T3-C3.
