Episode 2 of my video blog has been posted to YouTube. This is the second video in the Superloop antenna series, and shows the construction of a decade resistance box to use as the terminating resistance of the antenna. The box allows you to repeatably set the resistance to the value you want, as opposed to trying to make fiddly adjustments of a potentiometer. This part of the project went well, other than it having a 2 ohm offset due to resistance in the thumbwheel switches, wires, and banana plug connectors. Enjoy!
As noted in my recent upcoming projects post, I had three goals for this month. The video blog has debuted, and I’m still working on more material concerning this spring’s trans-Pacific AM broadcast band reception. But, a couple weeks ago I signed up for the local bi-monthly testing session to take the Technician exam, which is the first-level amateur radio licensing exam. The exam is relatively straightforward, and the question banks for all three exam levels are available online for studying. Even though you only need 26 out of 35 to pass, I got it in my head to try for a perfect score, which I accomplished this morning. Now I have to wait for my official application to get processed by the FCC before I get a call sign and can get on the air.
Finally! My first Arizona Signal Watcher video blog episode is now available on YouTube. This is the first of a several-part series on the “Superloop” receiving antenna. This design was developed by Bruce Conti and this is my take on the design and construction. The antenna is very useful and convenient when needing a signal null in one direction and good reception in other directions, and when portability is important. The first video is entitled “Superloop Antenna Part I: Introduction” and gives an overview of the antenna design and some theory behind it. Subsequent videos will detail the construction of the antenna and the electrical/electronic components needed to optimize the antenna performance. Comments here or on the YouTube page are very much welcomed. Enjoy!
