Odd propagation A couple of weeks ago, I turned on the rig, tuned up on 30 meters, and called CQ. The first station I worked was KB8FCG. According to QRZ.Com, KB8FCG is 28.8 miles away from me. The signal was S9 here in Ann Arbor. That seems a little too far for ground wave, but a little too close for sky wave. The second station I worked that even was S57V. QRZ.Com says that S57V is is 4,600 miles away. He gave me a 579 report. Is zero beating a lost art? Zero beating is the practice of matching your transmitting frequency to that of the station you’re calling or are in contact with. Because ..read more

One of the things on my ham radio bucket list was to learn how to use KiCAD and design a PC board. Being a newbie at PC board design (when I was an engineer, we had PC designers do the actual layout), I decided to do something simple. Since I teach ham radio classes, I decided to design a board based on the circuit in Figure T-1 of the Technician Class question pool. This diagram illustrates a couple of ideas: How schematic diagrams represent electronic circuits. How a transistor is used as a switch. Designing the board Since I already had the schematic, the first step in designing th ..read more

On Twitter, one of the accounts I follow is Michigan’sPast. His tweets are always interesting, and I’ve learned a lot. One of his recent tweets included this photo of the display of Michigan license plates at the R. E. Olds Museum in Lansing, Michigan: What jumped out at me was the W8AHV license plate in the third row. I didn’t know that Michigan offered ham radio license plates that far back. I re-tweeted this, and a fellow named Rory replied, “According to this article. 1939 may have been the first year in Michigan. http://www.pl8s.com/hams.htm” This article, written by Mike, W1DGJ, who is ..read more

From my reading list: The inner beauty of electronics

Safari, the web browser that I use most often, has a feature called the “reading list.” It’s like a bookmark, but much more temporary. The list is meant to be a parking lot for sites that you want to read, but not read over and over. Once you’ve read it, you’re supposed to delete the site from the list. Of course, a lot of sites get stuck on the list, so periodically I actually go through it and read some of the sites on the list. Here are three that I think hams will be as interested in as I am. The Inner Beauty of Basic Electronics Many components are not only marvels of electronics engineer ..read more

Operating Notes: Auroral flutter, big pileups for TN8K, more new ops?

I called CQ on 30 meters a couple of evenings ago and got a surprise call from R1DX in Saint Petersburg. What was notable about this contact was the auroral flutter on Vic’s signal. I wish I had recorded it. The sound is very distinctive, though, and Vic even commented on it. Here’s the great circle route between Ann Arbor, MI and St. Petersburg: It doesn’t seem like that route goes north enough to be affected by aurora, but I suppose that it could be. The signal may have also taken a more northern route and been affected by the aurora. If you’re a propagation guru, I’d like to hear what you ..read more
