Ferrite Chokes, What are They, Anyway?
In other OnAllBand entries, we’ve covered what ferrites are, how their behavior varies with frequency, and some of their applications in the ham station. This time, we’ll focus on their […]

In the OnAllBands entry, “What is Ferrite, Anyway?” we discussed what ferrite is and what makes up a “mix.” We also explored how ferrite behaves at different frequencies. Ferrite has […]
Ferrites are made from oxides of iron, cobalt (Co), barium (Ba), and strontium (Sr). The type of ferrite most useful to hams are soft ferrites. (The hard ferrites are good […]
DX Engineering now offers Color-Coded Ferrite RF Noise Reduction Kits covering a wider range of uses. Kits contain toroids and snap-on beads for specific RF suppression applications (linear amplifiers, AM […]
No matter what kind of operating you do, sooner or later you’ll need a “gadget” that isn’t readily available commercially. Maybe you’ll need a special switch or an interface between […]
This is the first of a two-part article about RF when you are operating “in the field,” meaning away from a fixed station. For example, when you are operating a […]
So you’re building a small dual-band Yagi and the instructions tell you to split the coax at the feedpoint. Stop right there. DX Engineering’s Michael Murphy, KI8R, shows you a […]
When cool weather approaches, you may begin to ponder the most efficient way to upgrade your existing antennas or add to your current capabilities. And when it comes to amateur […]
Here comes Field Day and all of your careful equipment connections and filtering go out the window as the station is disassembled and hauled off to the operating site. Be […]
After months of preparation, countless volunteer hours, and anticipation by thousands of hams who have had the dates circled in red for months, the wait is almost over! The gates […]
