Mostly Plastic Rotator Works – Passes Smoke Test
Well, my design for a cheap, mostly plastic rotator for small loop antennas works. It took me a while to get this built. Read more
Multi-turn Loop Calculator – Figure It Out
Design your next small transmitting loop with a free multi-turn magnetic loop calculator from DG0KW and others. Read more
Loop Remote Control Electronics Board
Here is my loop remote control electronics board. Not a PCB, but a 3D printed mount for all the electronics modules. Read more
L293D NodeMCU Motor Shield Works Fine
My low cost L293D Motor Shield will do the trick for remote controlling a new loop antenna. You can use a stepper to tune the antenna with rotation provided by a larger DC motor. Read more
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
