Electronic Communications’ Humble Beginnings:

eHam.net News – SCOTT AIR FORCE BASE, Ill. — When people think about the Air Force Network Integration Center, they immediately relate to their government email being migrated to the cloud or being the number one premier organization on cyber integration and standardization across the Air Force. The year 2018 marks the 75th anniversary of AFNIC. However, communications started much earlier. While communications dates back thousands of years, the effort towards electronic communications began in the mid-1800s. It was over 180 years ago that Samuel F. B. Morse received a patent for his electromagnetic telegraph. He devised a cipher code where words were assigned three or four-digit numbers and entered them into a codebook. Morse’s now famous message from the Bible, “What hath God wrought?” was sent May 24, 1824, 41 miles from Washington to Baltimore on an experimental line. Alfred Vail, Morse’s assistant in Baltimore, received and returned the same message that day. Vail advanced Morse’s original experiment and developed a more intricate numerical code using dots and dashes. Today, we are familiar with this as Morse code, which greatly increased the speed of deciphering messages and set the path for future electronic communications.

Amateur Radio Operators Invited to Summits on the Air:

eHam.net News – KINGSPORT — Amateur radio operators from throughout the Southeast will be coming to the Tri-Cities next month for a special event called Summits on the Air. Organizer Patrick Harris said the event will allow these radio operators — or “hams,” as they are sometimes called — to meet other hobbyists and engage in a bit of friendly competition. “Summits on the Air is an awards program (think trophies and certificates) where we hike to mountaintops, set up small portable radios and antennas and try to make radio contacts,” Harris said. “It is a bit like a scavenger hunt or, as I often tell people, it is like geocaching for ham radio.” ARRL, the national association for amateur radio, states that amateur radio is a hobby and service that “brings people, electronics and communication together.” “People use ham radio to talk across town, around the world, or even into space, all without the Internet or cell phones,” the ARRL website states. “It’s fun, social, educational, and can be a lifeline during times of need.”
