WSPR (pronounced "whisper") is an acronym for Weak Signal Propagation Reporter. It is a protocol, implemented in a computer program, used for weak- signal radio communication between amateur radio operators. The protocol was designed, and a program written initially, by Joe Taylor, K1JT. The software code is now open source and is developed by ...
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 ...
LPD433 (low power device 433 MHz) is a UHF band in which license free communication devices are allowed to operate in some regions. The frequencies correspond with the ITU region 1 ISM band of 433.050 MHz to 434.790 MHz. The frequencies used are within the 70-centimeter band, which is currently otherwise reserved for government and amateur ...
D-STAR (Digital Smart Technologies for Amateur Radio) is a digital voice and data protocol specification for amateur radio. The system was developed in the late 1990s by the Japan Amateur Radio League and uses minimum-shift keying in its packet -based standard. There are other digital modes that have been adapted for use by amateurs, but D-STAR ...
A cognitive radio (CR) is a radio that can be programmed and configured dynamically to use the best channels in its vicinity to avoid user interference and congestion. Such a radio automatically detects available channels, then accordingly changes its transmission or reception parameters to allow more concurrent wireless communications in a given band at one location.
The Joint Tactical Radio System (JTRS) as a Program of Record evolved from a loosely associated group of radio replacement programs to an integrated effort to network multiple weapon system platforms and forward combat units where it matters most – at the last tactical mile. In 2005, JTRS was restructured under the leadership of a Joint ...
Smart Radio Group purchased 4SB from Macquarie Regional RadioWorks in 2008 when a sale was forced when the company merged with Southern Cross Broadcasting, becoming Macquarie Southern Cross Media. Macquarie Regional Radioworks itself was formed after the merger of RG Capital and DMG Regional Radio which occurred in 2004.
