RA0SMS X-Phase Arrives from Irkutsk
Time to try some more analog devices for noise reduction and antenna phasing, starting with the RA0SMS X-Phase QRM Eliminator kit. Read more
Year in Review 2020 Diversity Reception
I have been playing with dual channel SDR for a few years. But in 2020 diversity reception took a major leap forwards with RSPduo and phased array. Read more
Year in Review 2020 Active Loop Antennas
During 2020 active loop antennas were my primary focus. Everything turned out pretty well with great performing wideband results. Read more
Universal Radio Tribute – A Long Run
Here’s to Universal Radio for its exceptional service to ham and shortwave radio enthusiasts around the world for thirty-seven years. Read more
Endfire Loop Array Patterns on Medium Wave
My small changes to phasing creates remarkably different endfire loop array patterns. I can demonstrate these with empirical results and analytical modeling. Read more
Loop Array Pattern Calculations
Using an Excel spreadsheet, I have created an easy way to visualize my loop array pattern as I change frequency and phasing in the dual channel SDR. Read more
Antenna Fun with Array Delay
Beamforming, or signal phasing with multiple antennas, means understanding array delay through the complete system. Here’s how it works. Read more
Diversity Reception Investment
I thought I would take a step back today and review my diversity reception investment. Along the way, I will try to answer the question “is it worth it”? Read more
