As amateur radio operators, we often take for granted our ability to easily reach out to the far corners of the globe. A late evening QSO with Europe, while exhilarating, is by no means uncommon. We’ll regularly trade ‘fish stories’ about that crazy contact that we made on low power with a ramshackle antenna but rarely stop to think about just how strange a notion this would be to someone not familiar with our hobby. Double this effect for anyone not familiar with the principals of RF communication, and HF communication in particular.
Amateur Radio: The Ultimate STEM Activity
How time does fly. It seems like just last week I made a post about my Field Day adventures in and around the Atlanta area. I explored the concept of Field Day as Amateur Radio’s open house and spending time with several different groups to learn what makes Field Day special for them. In truth, of course, it’s been a full 12 months and yet another Field Day is in the log. This year, I took Field Day on the road and spent the weekend with a marvelous group of young men and women up in the Boston, Massachusetts area.
A Winning Combination
Ding. The sound rang through the house. I was up in the kitchen, my shift for the day having come and gone, but the small sound from downstairs could have been a gunshot for the immediate effect it had. All conversation stopped and every set of eyes in the room snapped over to the small computer monitor glowing in the corner. The screen showed the combined logs for the weekend and the top line showed highlighted text. The small ding, the source of our excitement, was from one of a set of call bells, like what you might find at the front desk of a hotel, placed at each of the six stations downstairs, poised to be struck each time a new multiplier entered the log.
IC-7300 – The Shack’s Newest Addition
I was recently enjoying an afternoon in the shack, and while the HF bands were a bit flat that day, I still had fun looking at pictures of fellow amateurs’ stations as shown on the various ham radio websites. It’s always fun to see how various shacks are configured.
I tend to study the ergonomics of each layout, down to the vintage and models shown. Before long, I came across a picture of a guy’s re-staged novice day station. The receiver shown was far better than my trusty Hallicrafters S38, but it was this fellow’s novice transmitter that caught my eye! It was the mighty Ameco AC-1. This small-framed two-tube powerhouse featured crystal controls (novices could not use VFOs back then), two tubes (6V6 and 6L6) and plug-in coils for 80 or 40 meters–my choice (it did not cover 15). I spent my hard earned $20 on this baby, which may as well have been $2000 to this young op. Within minutes of my delivery, I had my soldering iron hot to the touch, and began building what was my very first kit project. The next day I completed the transmitter, plugged it into the AC outlet, and watched my new (and only) HF transmitter go up in smoke… a lot of very black, acrid, foul smelling smoke! My bedroom was spared the embarrassment and cost of a full-blown, working fire. I cannot recall there being actual flames, but I learned what burning insulated wire smelled like. My youthful and distressingly intrepid ego went up in smoke in that moment as well! The AC1 never fully recovered and my ego took a lot longer to be restored, such as it was for a 15 year old east coast kid.
The Need for Two Way Communications
This past weekend I saw the Jurassic World movie for the first time. Just as in all Jurassic Park movies, what starts out as an exciting journey with the possibility of viewing real live dinosaurs soon turns into a disaster. In the movie, a couple of boys are sent to the park by their parents during the holidays. A dangerous new dinosaur escapes as they are riding one of the park’s exciting attractions and the characters are unaware of the danger around them. When their aunt tries to contact them using a cell phone, the signal is unreliable and the call ends up dropping. While it was a great dramatic effect for the movie, it brings to light the need for two way radio communications.
Dayton Hamvention® – Welcome to the Big Show!
In amateur radio it doesn’t get any bigger, or any busier, than the Dayton Hamvention®. I like to call it The Big Show – it easily compares with a three-ring circus. For me, however, it’s far more than three rings!
HAMVENTION®
The Hamvention® started in 1952 as the Southwest Ohio Ham-vention. There were seven exhibitors and 200 flea market spaces. Over 600 visitors turned up that first year. In 2014 the official attendance was nearly 25,000 with over 2,000 flea market spaces and hundreds of exhibitors. Operated by the Dayton Amateur Radio Association, it truly is the premier gathering in amateur radio. You can find anything to do with amateur radio under the big top of the Dayton Hamvention®
