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.
CW Skimmer. CW Skimmer is a multi-channel Morse code ( CW) decoder and analyzer program for Microsoft Windows. It was created by Alex Shovkoplyas, VE3NEA, and is marketed by Afreet Software, Inc. CW Skimmer uses a sensitive CW decoding algorithm based on the methods of Bayesian statistics, which allows simultaneous decoding of all CW signals in ...
Morse code. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. [3] [4] Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy .
The FCC has finally dropped the requirement to learn the obscure language to become a ham radio operator; up until now there had been a five word per minute minimum Morse code speed requirement in ...
Add-on 455 kHz homemade BFO board. In a radio receiver, a beat frequency oscillator or BFO is a dedicated oscillator used to create an audio frequency signal from Morse code radiotelegraphy ( CW) transmissions to make them audible. The signal from the BFO is mixed with the received signal to create a heterodyne or beat frequency which is heard ...
In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression.The process of finding or using such a code is Huffman coding, an algorithm developed by David A. Huffman while he was a Sc.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes".
Modulated continuous wave (MCW) is Morse code telegraphy transmitted using an audio tone to modulate a carrier wave . Continuous wave (CW), by contrast, does not use a subcarrier, so there is no emission at all between Morse code symbols. MCW can be generated by any AM or FM radio transmitter with audio input from an audio oscillator or ...
The HamSphere software has two modulation types: Single-sideband suppressed-carrier transmission or SSB is the default mode of operation where the operator uses speech audio/phone. Continuous wave or CW where the operator utilizes a built-in Morse Code keyer.
