ham radio news

Milestones: N5FG, N3NL, ex-K1MAN Silent Keys Former CQ Worked All Zones Award Manager Floyd Gerald, N5FG, became a Silent Key in May. He had been in poor health after suffering a heart attack last year. Floyd was also co-founder of the Magnolia DX Association, the largest DX club in his native Mississippi. Low-power FM broadcast advocate Nickolaus “Nick” Leggett, N3NL, passed away in late April. An inventor with multiple patents to his credit, Leggett was bestknown as one of the leading proponents of establishing the Low Power FM broadcast service for local microstation broadcasting, according to RadioWorld. He also teamed up with Don Schellhardt, KI4PMG, to battle for reform of amateur radio antenna rules; and was a frequent commenter on a wide variety of amateur radiorelated petitions considered by the FCC.

“all the faces are ham faces”

Heading home from the Dayton Hamvention®, I thought about different titles for this month’s editorial, including “Back to Nature” (our booth was in a tent) and “A River Runs Through It” (did I mention that our booth was in a tent?). But the bottom line was that, despite the inevitable glitches that come along with moving a large event to new quarters on very short notice, the organizers pulled off a Herculean task, Dayton was still Dayton, and the Greene County Fairgrounds will be an excellent home for Hamvention in the long run. (We’re planning a photo tour of the show next month.) So it brings me back to finding a title, and the one you see at the top of this page was a comment I overheard as I…

our readers say...

April Issue the Best Ever Editor, CQ: I just wanted to congratulate all your authors of the various columns in the April issue. I think I spent more time reading that issue than I ever spent reading any issue of QST. Here’s a quick summary: Radio Foxhunting – great with lots of good info (however 73 had a devoted column decades ago that was really good too). Ham Radio Below 500 KHz – absolutely the best I’ve ever read on this subject! It was so interesting that I will probably get into at least listening. I didn’t realize such distances could be covered with such low power. Kit-Building – great too, I look at that column first before any other. Trends in 2017 – a bit scary but certainly thought-provoking — I had to re-read it…

oceanic wave height as a variable in predicting hf propagation

When it comes to propagation prediction, ham operators have a wide array of tools from which to choose. In addition to the routine reporting of Solar Flux Index, Sunspot Numbers, A/K indices, Bz values, solar wind speed, and other ionospheric condition measurements that are available from many websites, hams routinely utilize the Continental U.S. Band Conditions website <http://bit.ly/ 2qOEOmy> and the Voice of America Coverage Analysis Program website <www.voacap.com> to assist in making communication decisions. The Continental U.S. Band Conditions website operates in near real time and can be a valuable tool in alerting the ham operator to band openings that occur throughout the day. VOACAP provides a number of propagation probability tools and maps that project band conditions forward for up to 12 hours based on current space weather…

results of the 2017 cq wpx rtty contest

The 23rd running of the CQ WPX RTTY Contest had plenty of activity for all participants. There were 5,770 unique callsigns appearing at least five times across the 3,283 logs received. At the same time, the bulk of the activity shifted to the lower bands. One of the great things about the WPX contests is that low-band contacts earn twice the points as those on higher frequencies. So, even in between sunspot cycle peaks, even in the absence of 10- meter propagation, great scores were achieved. In fact, the proportion of QSOs on 10 and 15 meters hit an 8-year low this contest. Forty and 20 meters hosted the bulk of activity. The table below shows the percentage of QSOs on each band across all logs received for the last…
