blazing new trails with eels

Explore, Experiment, Learn, Share. These concepts — which we’ll dub EELS — have been at the heart of amateur radio’s technical ethos since the earliest days of our hobby. They are also at the heart of what this magazine — in fact, any ham radio magazine — is all about. Even in today’s digital world, a magazine is the pre-eminent way for amateur radio explorers and experimenters to share what they’ve learned with the broader ham community. We are proud to continue that tradition with the introduction this month of a new column on medium frequency (MF) and low frequency (LF) operating, in anticipation of FCC action in the near future to open up two new ham bands at 630 and 2200 meters. These bands present both challenges and opportunities to…

The Mystery of the Musical Fruit In December’s article on maker faires, we posed a question about a display in which pieces of fruit (connected by electrodes to a computer) were supposed to play musical notes when you touched them with one hand while touching a ground return (alligator clip to an Altoids® tin) with the other. In our case, touching the fruit caused the note to play even if there was no contact with the ground line. We couldn’t figure out how that worked and asked for your thoughts. We got two replies: Avery Finn, KØHLA, wrote: I believe it to be just another version of a theremin* that was popular several years ago. It operated by body capacity. No need to touch anything. No big mystery. Us old guys remember them. (*…

hamvention’s new home: “x (as in xenia) marks the spot”

In January, I was privileged to be asked to be the program presenter at the monthly meeting of the Dayton Amateur Radio Association, which sponsors the annual Dayton Hamvention®, the world’s largest hamfest. I presented some of my photos and musical slide shows of past Hamventions, some of which go back to the 1970s. I first made the trek to Dayton in 1975, as a college student at the University of Nebraska. I have seen 36 Hamventions at Hara Arena (Photo A), and when the time came for Hara to close, I, like many other hams, was apprehensive about the new location at the Greene County Fairgrounds in Xenia, Ohio (Photo B). Would it have the same kind of facilities? Would it be better? Will we be able to make…
