Antenna Modeling Software
If you have a moderate understanding of antennas, you can use antenna modeling software to better understand how your antenna creations work. 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
Trans-Pacific DX on Medium Wave – Get Up Early
After many years, I can finally receive Trans-Pacific DX on Medium Wave here in landlocked Calgary, western Canada. But I need to get up early for this! Read more
Wideband Receiving Loop Array Up and Running
It’s taken a while, but I finally have my wideband receiving loop array up and running. And, it works great for medium and short wave listening. Read more
SDRplay RSPduo Noise Canceller
Create an RSPduo noise canceller with a simple connection to noise probe antennas. Your results will match those of the ANC-4 or MFJ-1026. Read more
Solar Cycle 25 Starts – It’s Official
Solar cycle 25 should be a repeat of our last eleven year cycle. For the next five years, though, high frequency radio propagation will definitely improve. Read more
