Radio control (often abbreviated to RC) is the use of control signals transmitted by radio to remotely operate a device. Examples of simple radio control systems are garage door openers and keyless entry systems for vehicles, in which a small handheld radio transmitter unlocks or opens doors. Radio control is also used for control of model ...
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 communication and navigation facilities for aircraft.
A SINCGARS is being operated from within a HMMWV. Single Channel Ground and Airborne Radio System ( SINCGARS) is a very high frequency combat-net radio (CNR) used by U.S. and allied military forces. In the CNR network, the SINCGARS’ primary role is voice transmission between surface and airborne command and control assets.
AN/PRC-160. The AN/PRC-160 Wideband HF/VHF Manpack Radio is a tactical HF / VHF manpack radio manufactured by L3Harris. The PRC-160 is the manpack HF radio for the Harris Falcon III family of radios. It replaces the earlier AN/PRC-150, with a smaller form factor and lighter weight than its predecessor, and being capable of 4th Generation ...
Software-defined radio ( SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators / demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1] While the concept of SDR is not new, the ...
Distance measuring equipment. In aviation, distance measuring equipment ( DME) is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz). Line-of-visibility between the aircraft and ...
У = RF amplifier stages, Д = frequency discriminator stage. In radio equipment, Automatic Frequency Control ( AFC ), also called Automatic Fine Tuning ( AFT ), is a method or circuit to automatically keep a resonant circuit tuned to the frequency of an incoming radio signal. It is primarily used in radio receivers to keep the receiver tuned ...
A radio-controlled helicopter (also RC helicopter) is model aircraft which is distinct from a RC airplane because of the differences in construction, aerodynamics, and flight training. Several basic designs of RC helicopters exist, of which some (such as those with collective pitch control) are more maneuverable than others.
