Once and for all, let’s understand wideband versus narrowband mag loops. It’s a case of open and closed, circuits that is. Read more
Magnetic Loop Performance as Transducers
You will find a lot of confusion about magnetic loop performance, in particular about how they work differently from normal antennas. Let’s dig in. Read more
Electromagnetic Waves Work
While avoiding Maxwell’s Equations, we need a basic understanding of how electromagnetic waves work. We can’t live without them. Read more
Impedance Matching Test Jig 3D Printed
Another great ham radio use for a 3D printer is making an impedance matching test jig. Cheap and cheerful. Read more
Aluminum Core PEX Loop Antenna Material
You can make an aluminum core PEX loop antenna easily. This material is cheap, lightweight and easy to form a permanent loop shape. But hard to find! Read more
LTSpice Ham Radio Simulation – Great Learning Tool
LTSpice ham radio simulation is a great way to learn more electronics and design useful projects. Why have I waited so long to use it? Read more
Diversity Antennas Vision – Finding My North Star
I built my diversity antennas vision around two wideband loop antennas, at least 100 feet apart, all connected with shielded CAT 7 cable for signals and power. Read more
Think Learn Do – How My Mind Works
All of my projects embrace think learn do, a circular process of discovery. I think of an idea, do something, and learn along the way. Read more
Explore Delphi Community Edition
I thought it time to explore Delphi Community Edition, the free development platform released last summer. I did and it rocks. Read more
Magnetic Loop Magic Continues – Wideband Next
Looking back, I have had a lot of fun with magnetic loop magic. Next up, I will try my hand at wideband active loops for diversity reception. Read more
