The next meeting of the Arrow Communication Association will be on Wednesday, April 9, at 7:30 PM, Room BE-172 at Washtenaw Community College, 4800 E. Huron River Drive, Ann Arbor. We start gathering at 7 PM. At a brief business meeting, we will draw two winners of one Hamvention ticket each from all the people who have already purchased a Dayton Bus Trip ticket.
Next, Jerry Begel, W9NPI, will present his fourth “History of Telegraphy” lecture, called The Singing Arc–Unconventional Transmission Techniques.
He will again explore some “Things that we may have missed,” in a lively presentation that will cover:
the development of Needle and Sounder Telegraphy systems
Undersea Cable adventures
“What might have been:”
James Bowman Lindsey’s Underwater Wireless in the 1850s
Mahlon Loomis’ 1864 Aerial Communications Schemes (With his Redemption by cousin Mary Texanna Loomis)
Duddell’s Singing Arc experiments, with Poulsen’s refinements
Spinning Wheels: Yosami and Grimeton Stations in the 1920s, and why Mechanical Transmitters were essential throughout WW II.
I hope to see you there.
Mary Anne, W8VWY
