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 ...
The CW Operators' Club, commonly known as CWops, is an international organization, in membership and management, for amateur radio operators who enjoy communicating using Morse Code. Its mission is to foster the use of CW, whether for contesting, DXing, traffic handling, or engaging in conversations. [1] A CWops nominee must be capable of ...
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) .
Morse code is called the original digital mode. Radio telegraphy, designed for machine-to-machine communication is the direct on / off keying of a continuous wave carrier by Morse code symbols, often called amplitude-shift keying or ASK, may be considered to be an amplitude modulated mode of communications, and is rightfully considered the first digital data mode.
The original amateur radio operators used Morse code exclusively since voice-capable radio transmitters did not become commonly available until around 1920. Until 2003, the International Telecommunication Union mandated Morse code proficiency as part of the amateur radio licensing procedure worldwide.
Amateur radio propagation beacon. An amateur radio propagation beacon is a radio beacon, whose purpose is the investigation of the propagation of radio signals. Most radio propagation beacons use amateur radio frequencies. They can be found on LF, MF, HF, VHF, UHF, and microwave frequencies. Microwave beacons are also used as signal sources to ...
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. [1] The term "amateur" is used to specify "a duly authorized person interested in radioelectric ...
