CW Skimmer is a multi-channel Morse code decoder and analyzer program for Microsoft Windows.It was created by Alex Shovkoplyas, VE3NEA, and is marketed by Afreet Software, Inc.
Chart of the Morse code 26 letters and 10 numerals [1]. This Morse key was originally used by Gotthard railway, later by a shortwave radio amateur [2]. 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.
Many skilled Morse code operators can receive Morse code by ear mentally without writing down the information at speeds up to 70 wpm. [30] To write down the Morse code information manually at speeds higher than 20 wpm it is usual for the operators to use a typewriter or computer keyboard to enable higher speed copying.
At the coding level, prosigns admit any form the Morse code can take, unlike abbreviations which have to be sent as a sequence of individual letters, like ordinary text. On the other hand, most prosigns codes are much longer than typical codes for letters and numbers. They are individual and indivisible code points within the broader Morse code ...
A telegraph key, clacker, tapper or morse key is a specialized electrical switch used by a trained operator to transmit text messages in Morse code in a telegraphy system. [1] Keys are used in all forms of electrical telegraph systems, including landline (also called wire) telegraphy and radio (also called wireless) telegraphy .
In the five character groups event, random letters and numbers are sent in Morse code, five characters at a time, at a high speed. Separate competitions are held for the reception of just the twenty-six letters of the Latin alphabet , just the ten Arabic numerals , or a mixed content of letters, numbers, and some punctuation symbols.
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 ]
QRSS: Very slow speed Morse code QRSS uses very slow speed CW (Morse code) to compensate for the decreased signal-to-noise ratio involved in QRP operation. [ 11 ] [ b ] QRSS enthusiasts may record a transmission for later analysis, sometimes decoding "by ear" while playing it back at much faster speeds, or decoding "by eye" on the waterfall ...
