ham radio news

WRC-19 Under Way; Early Progress Reported The 2019 World Radiocommunication Conference (WRC-19) was under way in Egypt as we went to press. This quadrennial conference of the International Telecommunication Union sets worldwide policies and frequency allocations within the radio spectrum. The International Amateur Radio Union (IARU), which is an observer at the conference, reported that the first week’s sessions resulted in “no change” decisions relating to amateur allocations at 47.0-47.2 GHz and 5.850-5.925 GHz. Both of these spectrum areas are of interest to commercial users. The delegates also voted to defer any decision on spectrum allocations for wireless power transmission (WPT) for electric vehicles. Still to come as this is written — decisions on greater amateur access to the 6-meter band in Europe and Africa, and what issues to include on the…

West Point Cadets Contact Astronaut Via Ham Radio The U.S. military may have some of the world’s most sophisticated communications networks, but when it came to cadets at the U.S. Military Academy talking with astronaut and West Point alumnus Col. Drew Morgan aboard the International Space Station, the preferred method was via ham radio. The October contact between the U.S. Military Academy Amateur Radio Club, W2KGY, and Morgan, KI5AAA (operating as NA1SS) was organized through the Amateur Radio on the International Space Station (ARISS) program. The ground end of the contact was overseen by Col. Stephen Hamilton, KJ5HY, a research scientist at the Army Cyber Institute at West Point and Officer-in-Charge of the ham radio club, which has held W2KGY since 1937. Morgan is a 1998 West Point graduate, according to the Defense…

zero bias: a cq editorial

An interesting Facebook exchange came to my attention recently, one which wrapped up in a few simple comments much of the way in which we hams sometimes relate with non-hams, how we should relate with non-hams, and how we should relate with each other. The original post was by 2017 Newsline Young Ham of the Year Marty Sullaway, NN1C, who had just read the results of the 2019 CQ WPX CW Contest in our November issue and learned that his team at KC1XX had placed first in North America in the multi-operator, two-transmitter (M/2) category. (Congrats to Matt, Marty, and the rest of the team!) “Woohoo!” Marty wrote. “Another nice contest North American win. CQ WPX CW. Proud to be a part of the KC1XX M/2 team. We just edged out the…

ai meets ar

“OK, Google. Find me the Squidly Island DXpedition on 20 meters … and let me know when you’ve made the contact.” Is this a snapshot from ham radio’s future? WB2REM and K5PA say the technology for it is on the horizon. And some elements of artificial intelligence can be used in our ham shacks today. Artificial intelligence (AI) has permeated all aspects of our lives. We use AI devices to control lights, provide answers to questions, and instantaneously calculate math. So, why not use AI to enhance the amateur radio operating experience? This article provides proof of concept examples of how Amazon Alexa, Google Home Mini, Ultra Hal 7, and their variants can be used to accomplish this goal. Lastly, the future of AI in amateur radio (Photo A?) will be…

resurrecting a hi-z four receive array

Winter + Solar minimum = Prime time for the low bands! OH2RA shares his recipe for mixing a well-used receive antenna with some issues, a few new components, and a dose of new computer technology for optimizing the array; stirring well and putting out in the sub-arctic cold to harden up … and giving him a great new set of ears on 80 and 160 meters. My contest and remote station has never had proper low-band receive arrays due to the most common reason: Lack of space when two towers with plenty of higher band aluminum and gardening with the family fills the 3-acre space. And even with a spot available, a full SO2R (single-operator two-radio) station can’t really fit receive arrays so close to transmitting antennas as the available real…
