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.
Digital Signal 1 (DS1, sometimes DS-1) is a T-carrier signaling scheme devised by Bell Labs. [1] DS1 is the primary digital telephone standard used in the United States , Canada and Japan and is able to transmit up to 24 multiplexed voice and data calls over telephone lines.
FSK441, introduced in 2001 as the first communications mode included with WSJT, [3] is designed to support meteor scatter communication using radio-reflecting meteor trails. [2] The bursts of signal created by such trails are commonly referred to as "pings", due to their characteristic sound.
A signal strength and readability report is a standardized format for reporting the strength of the radio signal and the readability (quality) of the radiotelephone (voice) or radiotelegraph (Morse code) signal transmitted by another station as received at the reporting station's location and by their radio station equipment. These report ...
GNU Radio is a free software development toolkit that provides signal processing blocks to implement software-defined radios and signal processing systems. It can be used with external radio frequency (RF) hardware to create software-defined radios, or without hardware in a simulation-like environment.
A digital cross-connect system (DCS or DXC) is a piece of circuit-switched network equipment, used in telecommunications networks, that allows lower-level TDM bit streams, such as DS0 bit streams, to be rearranged and interconnected among higher-level TDM signals, such as DS1 bit streams.
The interface is often a DS1, with sync-status messages supplied by the clock and placed into the DS1 overhead. Line-derived timing A network element can choose (or be configured) to derive its timing from the line-level, by monitoring the S1 sync-status bytes to ensure quality. Holdover
Digital Signal Designation is the classification of digital bit rates in the digital multiplex hierarchy used in transport of signals from one location to another in telecommunications.
