Honda Recalls Several Generator Models Heads-up before you head out for Field Day … American Honda has recalled several models of its portable generators. The U.S. Consumer Product Safety Commission says the recall affects models EU2200i, EU2200i Companion, and EB2200i, colored red or camouflage. It says the generators can develop leaks from the fuel valve, posing fire and burn hazards, and advises purchasers to take them to an authorized Honda Power Equipment dealer for a free repair. Some 200,000 generators are involved in the recall. More information is available on the CPSC website at <>.

zero bias: a cq editorial

This is being written a week before this year’s Dayton Hamvention®, where Advertising Manager and Production Director Dottie Kehrwieder; Managing Editor Jason Feldman, KD2IWM; and I, along with several columnists, award mangers and contest directors, will staff the CQ booth, visit with manufacturers and dealers, and lead or take part in various forums and other events. Collectively, this group of staff members, contributing editors and award/contest managers are the “public face” of our magazine, representing us to the amateur radio community and industry. But there’s another group of people behind the scenes whose work is at least equally important to CQ’s success, but who are rarely recognized. This seems like a good time to do that, and to say “thank you.” Art Director Liz Ryan and Production Manager/Sales Coordinator Emily Leary…

W5LFL, First Ham in Space, SK Former astronaut Owen Garriott, W5LFL, the first person to operate an amateur radio station from space, has become a Silent Key at age 88. He died April 15th at his home in Huntsville, Alabama. Garriott held a Ph.D. in electrical engineering from Stanford University, where he also taught before joining NASA in 1965 as a scientist-astronaut. According to NASA, he authored or co-authored more than 40 scientific papers and one book on ionospheric physics. Garriott’s first trip to space was aboard Skylab 3 in 1973, where he and crewmates Alan Bean and Jack Lousma spent nearly two months, at that point the longest single-mission spaceflight on record. He returned to space in 1983 aboard the shuttle Columbia, a 10-day science mission known as STS-9/Spacelab-1. During this flight,…

finding my true north

The title of this article might sound like a way to align your beam antenna correctly when installing it on a tower. As appropriate as such an article would be in this publication, this one is more about finding myself, doing something outside of my comfort zone that would end up being one of the best experiences of my life, how I accomplished it and how you could, too. Rewind to May 1990. I had just graduated from Michigan Technological University in Houghton, Michigan with a degree in electrical engineering and was ready to start my career. A couple of my buddies who graduated with me took the time to visit nearby Isle Royale National Park (ISRO), located in Lake Superior, for several days after graduation. While I was invited to…
