VHF transmitter T-23/ARC-5 and HF transmitter T-20/ARC-5 on rack MT-71/ARC-5. The AN/ARC-5 Command Radio Set is a series of radio receivers, transmitters, and accessories carried aboard U.S. Navy aircraft during World War II and for some years afterward. It is described as "a complete multi-channel radio transmitting and receiving set providing ...
A typical motor start capacitor. A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run ...
An instant start ballast does not preheat the electrodes, instead using a relatively high voltage (~600 V) to initiate the discharge arc. It is the most energy efficient type, but yields the fewest lamp-start cycles, as material is blasted from the surface of the cold electrodes each time the lamp is turned on.

About 1/8 wavelength long: (left) 200 MHz stub is 19 cm, (right) 300 MHz stub is 12.5 cm 10 kW FM broadcast transmitter from 1947 showing quarter-wave resonant stub plate tank circuit. In microwave and radio-frequency engineering, a stub or resonant stub is a length of transmission line or waveguide that is connected at one end only. The free ...
Fug 21: A 0.1 - 10 MHz receiver paired with a 2.5 - 7.5 MHz transmitter. Fug 24: A 0.1 - 7.1 MHz receiver paired with a 3 - 7.5 MHz transmitter. Fug 25: A 2.5 - 27.5 MHz receiver paired with a 3 - 16.6 MHz transmitter. FuSpr.a: A high-band HF transceiver. It operated in the 24.1 to 25 MHz (24100 to 25000 kHz) frequency range with a transmission ...
Automatic Link Establishment, commonly known as ALE, is the worldwide de facto standard for digitally initiating and sustaining HF radio communications. [1] ALE is a feature in an HF communications radio transceiver system that enables the radio station to make contact, or initiate a circuit, between itself and another HF radio station or network of stations.
