He gives us his studied impressions. Your Radio: A Homeschooling Resource 13 By Georg Wiessala Now at over 100 years old, radio continues to prove its worth in modern education. From his own experiences in using his trusted shortwave radio to teach at school and university and the current global lockdown and widespread social distancing efforts, Georg proposes parents and teachers can benefit from using radio as an added resource to limited in-school education in a number of subjects. He offers six scenarios for educators and teach-at-home parents that may prove useful as schools try to “return to normal” activities this fall. 100 Years of Radio Series 18 Reginald Fessenden: Sadly, Little more than a Blip on the Wireless Timeline By Richard Fisher KI6SN In his time, Professor Reginald Fessenden was a towering figure in the radio industry. The industrious academic turned litigious entrepreneur racked up a fortune from his patents and storied lawsuits against his competitors. But it was his achieve- ment on Christmas Eve 1906 that became the stuff of legend—credited by many with the first broadcast of voice and music over the air. But, for whatever reason, there appears to be little documented evidence of the broadcast. Richard travels through the fog of his legacy in search of the truth. Living with a Hex Beam 22 By Robert Gulley K4PKM Many of us have coped with compromised antennas as we make do with the limited real estate at our command, none more so that Robert, whose 25 x 35-foot backyard presents some serious limitations. Because of additional difficulties in living in an historic neighborhood, he never dreamed an HF beam antenna would be in his future—until he met the Hex Beam. TSM Reviews: 27 Yaesu FTM-300DR Transceiver By Cory GB Sickles, WA3UVV When Yaesu introduced its C4FM digital transceiver concept at Hamvention 2012, there was little to show other than a diminutive FT1DR portable, sitting under a Lucite cover. Today, Yaesu’s C4FM-based FTM-300DR bears some resemblance to its previous relatives, the FTM-100DR and FTM-400DR, it is chock-full of new firmware and features, which are not readi- ly apparent until you start exploring and using the radio. Cory takes us on a tour of the versatile transceiver. 2 The Spectrum Monitor September 2020 Scanning America 32 The World of Shortwave Listening 67 By Dan Veeneman By Jeff White, Chairman, HFCC Scanning California Wildfires Virtual Frequency Coordination for Shortwave Stations?

You don’t suppose the lead-in might have some effect on its efficiency, do you? “However, the underground antenna consisting of a wire in a bamboo pipe buried 18 inches underground was indeed used successfully in emergency situations in Vietnam by Special Forces using the AN/GRC-109 in jungle encamp- ments according to my sources, but again we do not know the length of the lead in wire or its effect. https://people. ohio.edu/postr/bapix/GRC109.htm It’s definitely an inter- esting area for basic research with today’s more sophisticated measuring instruments.” – Rich Post KB8TAD July 1919 issue of Electrical Experimenter Science and Inven- tion magazine, a Hugo Gernsback publication, reports on the use Editor’s Note: In addition to being the columnist for of trees as antennas.
