The first message sent by Morse code\u2019s dots and dashes across a long distance traveled from Washington, D.C., to Baltimore, MD on Friday, May 24, 1844 \u2014 175 years ago. It signaled the first time in human history that complex thoughts could be communicated at long distances almost instantaneously. <\/span>Until then<\/a>, people had to have face-to-face conversations; send coded messages\u00a0<\/span>through drums<\/a>,<\/span>\u00a0smoke signals<\/a>\u00a0and\u00a0<\/span>semaphore systems<\/a>; or read printed words.\u00a0 Thanks to Samuel F.B. Morse, communication changed rapidly, and has been changing ever faster since. He invented the electric telegraph in 1832.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.9.2″ _module_preset=”default”][et_pb_row _builder_version=”4.9.2″ _module_preset=”default” min_height=”242px”][et_pb_column type=”4_4″ _builder_version=”4.9.2″ _module_preset=”default”][et_pb_image src=”https:\/\/mohawkarc.com\/wp-content\/uploads\/2021\/03\/image001.jpg” title_text=”image001″ align=”center” _builder_version=”4.9.2″ _module_preset=”default”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.9.2″ _module_preset=”default”][et_pb_column type=”4_4″ _builder_version=”4.9.2″ _module_preset=”default”][et_pb_text _builder_version=”4.9.2″ _module_preset=”default”]<\/p>\n It took six more years for him to standardize a code for communicating over telegraph wires.

Radiotelegraphy, the proper name, descends from landline (wired) telegraphy of the 19th century, and retains some of the old culture, including a rich set of abbreviations and procedures. Morse messages sent by spark gap transmitter were the first wireless communications mode. These \u201cdamped waves\u201d were very broad and inefficient for communication. They were soon replaced by \u201cCW” transmission, using vacuum tube oscillators that were capable of a very pure note.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.9.2″ _module_preset=”default”][et_pb_column type=”4_4″ _builder_version=”4.9.2″ _module_preset=”default”][et_pb_image src=”https:\/\/mohawkarc.com\/wp-content\/uploads\/2021\/03\/image004.jpg” title_text=”image004″ align=”center” _builder_version=”4.9.2″ _module_preset=”default”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.9.2″ _module_preset=”default”][et_pb_column type=”4_4″ _builder_version=”4.9.2″ _module_preset=”default”][et_pb_text _builder_version=”4.9.2″ _module_preset=”default”]<\/p>\n Before the invention of the telegraph, most messages that had to be sent over long distances were carried by messengers who memorized them or carried them in writing. These messages could be delivered no faster than the fastest horse. Messages could also be sent visually, using flags and later, mechanical systems called semaphore telegraphs, but these systems required the receiver to be close enough to see the sender, and could not be used at night.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.9.2″ _module_preset=”default”][et_pb_column type=”4_4″ _builder_version=”4.9.2″ _module_preset=”default”][et_pb_image src=”https:\/\/mohawkarc.com\/wp-content\/uploads\/2021\/03\/image007.jpg” title_text=”image007″ align=”center” _builder_version=”4.9.2″ _module_preset=”default”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.9.2″ _module_preset=”default”][et_pb_column type=”4_4″ _builder_version=”4.9.2″ _module_preset=”default”][et_pb_text _builder_version=”4.9.2″ _module_preset=”default”]<\/p>\n The telegraph allowed messages to be sent very fast over long distances using electricity. The first commercial telegraph was developed by William Forthergill Cooke and Charles Wheatstone in 1837.

Short signals are referred to as dits (represented as dots). Long signals are referred to as dahs (represented as dashes). The code was converted into electrical impulses and sent over telegraph wires. A telegraph receiver on the other end of the wire converted the impulses back into to dots and dashes, and decoded the messages In 1844, Morse demonstrated the telegraph to the United States \u00a0Congress using a now famous message \u201cWhat hath God wrought\u201d<\/strong>.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.9.2″ _module_preset=”default”][et_pb_column type=”4_4″ _builder_version=”4.9.2″ _module_preset=”default”][et_pb_image src=”https:\/\/mohawkarc.com\/wp-content\/uploads\/2021\/03\/image017.jpg” title_text=”image017″ align=”center” _builder_version=”4.9.2″ _module_preset=”default”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.9.2″ _module_preset=”default”][et_pb_column type=”4_4″ _builder_version=”4.9.2″ _module_preset=”default”][et_pb_text _builder_version=”4.9.2″ _module_preset=”default”]<\/p>\n Today, modern Amateur Radio transceivers use solid state components and microprocessors to support a variety of communication modes including CW, voice, image and many digital data modes.\u00a0 Straight Keys, are still used today for sending Morse code.\u00a0 More modern methods of sending \u201cCW\u201d include\u00a0 Straight Keys, \u201cBugs\u201d, and electronic devices called \u201cpaddles\u201d shown below.
