CQ Highlights – July 2019

The July issue of CQ takes you on the road to the Dayton Hamvention®, to a new computer museum and to the far reaches of the solar system! We start – on the front cover – with a tribute to the 50th anniversary of the first manned moon landing in July, 1969, as well as a look ahead to the possibility of lunar DXpeditions in the not-too-distant future. And NW7US's Propagation column takes us all on a trip through space on the solar wind! Back on Earth, K8HSY and WB5VQX offer tips on converting old computer power supplies to useful accessories in your ham shack; WB9YBM shows us how to design a customized active audio filter; and W2IY shares "An Odd HF Propagation Experience." We've also got the results of the 2019 CQWW RTTY WPX Contest; our latest inductees into the CQ Amateur Radio, Contest and DX Halls of Fame; and a photo tour of the 2019 Dayton Hamvention®.

Among our columns, "Math's Notes" looks at multicolor LEDs (light-emitting diodes), "Listening Post" editor Gerry Dexter shares news of upcoming (not-so-good) changes in U.S. government shortwave broadcasting; and Emergency Communications Editor W4ALT features an "Interview with a Dead Man.

We've got visits to the Ozarkcon QRP gathering, a local maker space, the Bay Area Maker Faire, and a brand new (not-yet-open) computer museum in suburban Atlanta. "Magic in the Sky" editor AA6JR takes us on a trip back in time as he reminisces about the first moon landing in 1969; "VHF Plus" editor K8ZR previews a couple of griDXpeditions planned for this summer, and MF/LF Editor KB5NJD shows us how to calculate EIRP – Effective Isotropic Radiated Power – which is essential to know if you're operating on 630 or 2200 meters and not as difficult as you may think.

All that and more is coming up in the July issue of CQ magazine. For information on becoming a CQ subscriber - to either our print or digital edition - click the "Click Here to Subscribe" button at the top of this page.

Apollo 11 landed the first men on the moon 50 years ago this month. NASA is now planning to return. Could there be a lunar DXpedition in our not-too-distant future? Or are these astronauts making Moon-Earth-Moon contacts with another lunar colony? W2VU discusses the possibilities in his Zero Bias editorial in this issue.
