Arduino Returns to My Maker Workbench
After four years absence, Arduino returns to my top of mind. Time to do some more remote motor control projects. Read more
QST Inspires My Next Loop Project
Nearly every issue of QST inspires me to do something new or different. Now I am going to try another small transmitting loop. Read more
Cold Weather Loop Performance
Now that I have been through most of a Calgary winter, I thought a few comments were in order about cold weather loop performance. Read more
Wideband Loop Compendium Update
Feel free to click the links and enjoy the details presented in my wideband loop compendium update covering my experiments and learnings over the past two years. Read more
RFI Spectrum Hunter Loop
By combining TinySA with my direction finder, I may be able to create a lightweight RFI spectrum hunter loop. Just the ticket for tracking down noisy neighbors. 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
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
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
