In addition to Motorola, at least two other companies make compatible base station decoders for MDC-1200. Motorola radios with MDC options have an option allowing the radio to filter out data bursts from the receive audio. Instead of hearing the AFSK data, the user hears a short chirp from the radio speaker each time a data burst occurs. (The ...
A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal . [ 1 ] It is commonly applied to sonar , radar , and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum ).
A PRC-117 radio and SATCOM antenna. The AN/PRC-117F/G radio is currently in use with the United States Navy Seabee and EOD teams in their MRAP and JERRV vehicles. [2] The radio is also in use by the United States Marine Corps, [6] United States Army, [7] USSOCOM, [8] United States Coast Guard, United States Air Force, [9] Royal Air Force, [10] Dutch Army, Spanish Air Force, British Army ...
Single Channel Ground and Airborne Radio System (SINCGARS) is a very high frequency combat network 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 (C2) assets.
Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. The following is a list of devices that support the technology from various UWB silicon providers.
In digital communications, chirp spread spectrum (CSS) is a spread spectrum technique that uses wideband linear frequency modulated chirp pulses to encode information. [1] A chirp is a sinusoidal signal whose frequency increases or decreases over time (often with a polynomial expression for the relationship between time and frequency).
Chirp (also known as Asio Limited) was a technology company based in the UK. [1] Chirp was originally a research project from UCL and was incorporated as a UK limited company in 2012. [ 2 ] Chirp specialised in data-over-sound software development kits , [ 3 ] which converted data into audio signals, which could be transmitted to other devices ...
Motorola radios with MDC options have an option allowing the radio to filter out data bursts from the receive audio. Instead of hearing the AFSK data, the user hears a short chirp from the radio speaker each time a data burst occurs. (The user must turn on this feature in the radio's option programing settings).
