Supplemental ideas that could work with the 2021 Winter Build Project! If you haven’t heard of the Arduino, where have you been?! For those that are wondering, the Arduino is an open-source microcontroller platform that is inexpensive, easy to learn, and very well documented. The Arduino microcontroller comes in many different packages, depending on the […]

Quick Multimeter Test Jig
Recently I had the need to test a handful of through hole resistors. I’ve had this need before when going through drawers of discarded components as well. Being colorblind, it’s not even helpful for me to memorize the color code, so I have to measure them. I’m all about simplification, so simplifying the setup, handling, […]
Kit Building Resources
Here are some resources to learn the basics of soldering, tool use, and building of electronic kits. This is a supplement to the 2021 Winter Build Project, but is a great resource for anyone trying out soldering for the first time!

Microcontroller Projects for Amateur Radio
Book Review “Microcontroller Projects for Amateur Radio” is a great book for folks with some background with microcontrollersand have a knack for improvising and troubleshooting. That may sound like a left-handed complement, but read on. It was submitted to ARRL for publication two years before it hit the ARRL Store. Every schematic was redrawn, which […]

Satellite Ops – Where to Start?
So far, I’ve yet to make a satellite contact using the FM repeaters available. Seems I’m either not fast enough, the repeater is down, or my equipment isn’t right. There’s always SOMETHING that works against me! EDIT: Finally made a contact on Oct 8, 2020 on SO-50! Sample audio in the article below! So, why […]
How Does the J-Pole Work?
J-Pole antennas are one of the true works of electrical engineering that gives us a smaller footprint vertical with no need for a ground plane. But how do these things work? Here is a great presentation from Dr. Ed Fong WB6IQN explaining. Other articles and information on J-Poles available here: The DBJ-1: A VHF-UHF Dual-Band […]
