R-S-T system. S-Meter (ICOM IC-732 HF Transceiver) The R-S-T system is used by amateur radio operators, shortwave listeners, and other radio hobbyists to exchange information about the quality of a radio signal being received. The code is a three digit number, with one digit each for conveying an assessment of the signal's readability, strength ...
An amateur radio satellite is an artificial satellite built and used by amateur radio operators. It forms part of the Amateur-satellite service. [1] These satellites use amateur radio frequency allocations to facilitate communication between amateur radio stations. Many amateur satellites receive an OSCAR designation, which is an acronym for ...
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 ...
WSJT (amateur radio software) WSJT-X is a computer program used for weak- signal radio communication between amateur radio operators. The program was initially written by Joe Taylor, K1JT, but is now open source and is developed by a small team.
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 ...
PACTOR (Latin: The mediator) was developed by Special Communications Systems GmbH (SCS) and released to the public in 1991. [1] PACTOR was developed in order to improve the reception of digital data when the received signal was weak or noisy. [1] It combines the bandwidth efficiency of packet radio with the error-correction (CRC) and automatic ...
Amateur teleprinting over radio (AMTOR) D-STAR (Digital Data) a high speed (128 kbit/s), data-only mode. Hellschreiber, also referred to as either Feld-Hell, or Hell a facsimile-based teleprinter. Discrete multi-tone modulation modes such as Multi Tone 63 (MT63) Multiple frequency-shift keying (MFSK) modes such as. FSK441, JT6M, JT65, and FT8.
