CQ Highlights - May 2021

The effects of the Coronavirus pandemic continue to be reflected in the pages of CQ. We start our May issue with a look at a 40-meter net whose members are using ham radio to coordinate their efforts to make vaccine appointments for family members, friends and neighbors. That's followed by the results of last year's CW weekend of the CQ World Wide DX Contest which continues the 2020 streak of record participation – yet fewer countries activated – due to COVID-19 travel restrictions.

We've also got three antenna articles – one of which is a CQ Classic from exactly 75 years ago this month – as well as a multi-band off-center-fed dipole and a hammock Yagi. Among our columns, WA2NDM writes in "Math's Notes" about simple test equipment for experimenters; "Listening Post" editor Gerry Dexter remembers Bob "Big Signal" Brown, KW3F, who recently became a Silent Key; K0NEB writes in this month's Kit-Building column about the DX Engineering NOISELOOP QRM Shifter; "Ham Notebook" editor KH6WZ looks at Makers, Youth and Ham Radio, and "Digital Connection" editor plugs into a solar power system for his ham shack.

That's just a glimpse of what's ahead in the May issue of CQ, available in both print and digital editions. For information on becoming a CQ subscriberClick here to subscribe!.
