First-Ever Lunar Repeater QSO Reported Amateur radio science and technology blogger Daniel Estévez, EA4GPZ/MØHXM, is reporting that DK5LA in Germany contacted BY2HIT at the Harbin Institute of Technology in China on July 1 using the GMSK-to-JT4G repeater aboard the lunar-orbiting LO-94 (DSLWP-B) satellite. It is the first-ever amateur contact made through a lunar-orbiting satellite transponder. The Chinese LO-94 satellite took photos of the moon’s shadow as it crossed the Earth during the July 2 total solar eclipse (seen in the Southern Hemisphere). One image is posted on the CQ Newsroom at <http://cqnewsroom.blogspot.com>. First-Ever Transatlantic 2-Meter QSO Reported Speaking of first-evers, the Monteverde Contest Team in the Cape Verde Islands has achieved a long-sought goal of making a transatlantic contact on the 2-meter band. According to Newsline, D41CV used 500 watts and six stacked…

Widely Divergent Perspectives The following two letters are in response to the article, “Hamming and Hunting,” by Terry Joyner, W4YBV, in the June issue of CQ: Dear Terry, I’m officially jealous. I just received the June edition of CQ and read your article about combining two of your hobbies. I’m a deer hunter, too, in Nebraska but don’t own any land. I’m lucky if I get permission to hunt on private land. I’m one of those city hunters, I live in the Omaha metro area. What you’ve done is awesome; I know all about the hours of watching much of nothing in the woods. A friend of my mine described deer hunting perfectly; hours of boredom interrupted by brief moments of exhilaration followed by a lot of work that isn’t much fun. More power to you.…

zero bias: a cq editorial

Even Jules Verne couldn’t imagine this one1 … and it flew right past us last month, when we speculated on our cover about how soon we might see a lunar DXpedition. You might not be aware of this, but since last year, there has been a ham radio satellite orbiting the Moon, primarily sending back photos from the dark side in response to commands from hams on Earth. But if that wasn’t cool enough, LO-94 (Lunar OSCAR-94) also carries a 70-centimeter digital (GMSK-to-JT4G2) repeater and, on this past July 1, DK5LA in Germany used that repeater to contact BY2HIT at the Harbin Institute of Technology in China, where the satellite was built. It was the first time an amateur radio contact had been made through a satellite transponder in lunar…

Medical Imaging + Ionospheric Science = Physics Medal for MØIBG Dr. Cathryn Mitchell, MØIBG, is the latest recipient of the Edward Appleton Medal and Prize from England’s Institute of Physics. Mitchell, who is the Academic Director of the University of Bath Doctoral College, was recognized for developing “a completely new Earth observation technique by adapting medical tomography to image the Earth’s ionosphere, thus revealing the dynamics of the near-Earth space environment,” according to the Institute’s announcement, which continued, “Her use of Global Positioning System satellite signals as a source for space weather tomography, through a new time-dependent mathematical inversion algorithm, has given us the first global-scale view of the ionosphere in response to space weather storms.” “Mitchell’s research has fundamentally changed our understanding of the Earth’s ionosphere,” according to the announcement, and…
