Prototype Magloop Baseline Data
Before I start experimenting, it was time to collect some prototype magloop baseline data. My antenna analyzer come in handy. Read more
Prototype Magnetic Loop Assembly Made and Mounted
So, my journey begins, starting with a prototype magnetic loop assembly. A starting point for what’s to come, and maybe even part of my finished product. Read more
Wideband versus Narrowband Mag Loops
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
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
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
Geomagnetic Activity Effects HF Propagation
It seems like even small bumps in geomagnetic activity are ruining HF radio propagation for me this summer. Beware a K Index more than 2! Read more
Mysterious Radio Kuwait Fading
Digital broadcasting can provide excellent quality on shortwave. But recently I have discovered mysterious Radio Kuwait fading of some sort. Read more
