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
Radio Spectrum Watching Expectations
So, are you achieving your radio spectrum watching expectations? Let’s take a look at the details of display optimization.

SdrDx Spatial Filtering with Afedri Receiver
I finally got around to SdrDx spatial filtering. The phasing control in SdrDx software works really well with my Afedri AFE822x. Read more
Multiple Receiver Monitoring with SDR
Multiple receiver monitoring is the new normal with software defined radio. Here is how your SDR accomplishes this magic. Read more
Watching Signal Amplitude – Why DFT Uses Windowing
Watching signal amplitude is easy on software defined radios. But accurate DFT displays need to be cleaned up with windowing. Here’s why and how. Read more
