New FCC RF Exposure Rules Take Effect May 3rd Back in 2019, the FCC adopted new rules relating to radio frequency (RF) exposure levels which ended amateur radio’s categorical exemption making station evaluations. (The exposure limits have not changed, just the methods used to make measurements and the elimination of categorical exemptions. –ed.). The rules were not implemented immediately in order to give hams and other licensees time to figure out how to meet the new requirements. Time’s up. The new rules take effect on May 3rd and affect all of us. Here are key points relating to amateur stations, according to the ARRL: • Existing stations have an additional two years in which to determine whether an evaluation is required (and if it is, to do it); • New stations or existing…

zero bias: a cq editorial

Flipping a Switch Propagation continues to fascinate me, even after several decades, as I now enter my sixth sunspot cycle (I became a ham at the peak of Cycle 20 and knew nothing of sunspot cycles at the time). I’ve learned a tremendous amount since then, especially over the last several months as I’ve worked closely with Carl Luetzelschwab, K9LA; Ted Cohen, N4XX; and Caryn Eve Murray, KD2GUT, on the 4th edition of the CQ Shortwave Propagation Handbook. I now understand much more of the science involved and the mechanics behind the path that a radio signal travels when it leaves my antenna, and the possibly different path that is followed by a returning signal. But understanding the mechanics doesn’t change the sense of wonder for me when I’m actually on…

Hams often complain about questions on our FCC license exams, suggesting they’re either too easy, out of date, or not reflective of current activities or the privileges granted by the license class in question. Well, here’s your chance to do more than complain. The Question Pool Committee (QPC) of the National Conference of Volunteer Examiner Coordinators (NCVEC) is asking for the ham community’s input on the Element 2 exam that will be used for Technician Class license exams given between July 2022 and June 2026. The QPC is interested in hearing comments and suggestions relating to existing questions as well as proposed new questions for the revised question pool. The NCVEC website <www.ncvec.org> offers the following guidelines: • When submitting actual questions for QPC review please provide the following in plain ASCII…

the ham radio hunger games

Ham Radio’s Contribution to Seeking COVID-19 Vaccines The Hunger Games franchise (2012-2015) is a dystopian adventure film series.1 It is based on the premise that winners, through combat with other districts, could elevate family status and thus provide food, security, and a better life for their families. In real-life society today, the COVID-19 pandemic has ravaged whole families, taking the lives of more than half a million people in the U.S. alone. Given the amateur radio community’s aging population, we have not been spared. In January 2021, the COVID-19 vaccine was first slated to be distributed to elderly people and medical workers. However, given the demand in such states as Florida, where I reside, it was extremely difficult to get an appointment. In my case, I tried to get appointments through the…

cw results of the 2020 cq world wide dx contest

A lthough the 72nd CQWW CW contest is in the rearview mirror, the memories from the weekend continue. While SSB conditions were an improvement over the previous year, CW turned out to be a significant step above that. In fact, your feedback tells the real story. Each year, we receive over 1,500 soapbox comments with your logs, mostly expressing enthusiasm and excitement over the conclusion of yet another successful CQWW contest. In a sample of this year’s group, you said: “My first HF-CW-Contest! Thanks for all contacts!” – DB5DY “Getting back on the air with indoor 10M dipole after 30+ years.” – KB2DSR “First CQWW CW contest, and for sure not the last! Real fun!” – SEØP “Great to see 10 meters alive!” – VK5GR The 2020 CQWW CW contest was unique in many ways. Of…
