Proprietary. macOS. MacLoggerDX is a full-featured amateur radio contact logger for macOS with Transceiver control, Rotor control, Callbook lookup, QSL handling (Hardcopy / LoTW / eQSL / Club Log), DX Cluster and spotting, and basic contesting support. It also works with WSJT-X to control the transceiver while making digital contacts, etc.
Amateur radio users in the U.S. and Canada have used the R-S-T system since 1934. This system was developed by amateur radio operator Arthur W. Braaten, W2BSR. It reports the readability on a scale of 1 to 5, the signal strength on a scale of 1 to 9, and the tone of the Morse code continuous wave signal on a scale of 1 to 9.
R-S-T system. For other uses, see RST (disambiguation). 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 ...
WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions. Transmissions carry a station's callsign, Maidenhead grid locator, and transmitter power in dBm. The program can decode signals with a signal-to-noise ratio as low as −28 dB in a 2500 Hz bandwidth.

A broadcast translator is a low-powered (maximum of 250 watts) FM radio station that retransmits the programming of a parent station that operates on a different frequency. Translators are not allowed to originate programming, and were originally designed to extend the coverage area of a primary analog FM station.
Radioteletype ( RTTY) is a telecommunications system consisting originally of two or more electromechanical teleprinters in different locations connected by radio rather than a wired link. Radioteletype evolved from earlier landline teleprinter operations that began in the mid-1800s. [1] The US Navy Department successfully tested printing ...
D-STAR. ICOM IC-91AD handheld transceiver with the D-STAR UT-121 digital voice board installed. 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 ...
In amateur radio, QRP operation refers to transmitting at reduced power while attempting to maximize one's effective range. QRP operation is a specialized pursuit within the hobby that was first popularized in the early 1920s. QRP operators limit their transmitted RF output power to 5 W or less regardless of mode (Some call 10 W on Phone QRP) .
Fast Simple QSO (FSQ) is an amateur radio digital differential frequency modulation mode developed by Con Wassilieff ZL2AFP with Murray Greenman ZL1BPU in 2015. [1] FSQ is used primarily on HF on fixed frequency channels.
