Loop Construction Modular Approach
Since the start, I have taken a loop construction modular approach which makes it easy to experiment with different ideas. Read more
Mostly Plastic Wideband Receiving Loop
With aluminum core PEX, we have created a mostly plastic wideband receiving loop that should survive Calgary’s weather extremes. Only time will tell how well it holds up. Read more
DIY Wideband Loop Rotator Concept
Here is a DIY wideband loop rotator concept that should work with either stepper or DC geared motors and cost less than $30 to build. Let’s take a look. Read more
Loop Rotation Options Considered
You should check out wideband loop rotation options if you plan to use the antenna for low-angle DX reception at long, medium and lower HF frequencies. What are the options? Read more
LZ1AQ Amplifier PCB Build – Try Surface Mount
Read this description of my LZ1AQ amplifier PCB build. Add a one meter loop and some CAT cable and you have a complete wideband magnetic loop that works well. Read more
LZ1AQ Loop Amplifier Project Printed Circuit Board
So, great news. I have taken the original LZ1AQ loop amplifier project, fabricated a custom PCB and built it with surface mount parts. It works great. Read more
LZ1AQ Breadboard Performance – Basement Adventures
My early tests with LZ1AQ breadboard performance are very encouraging, even with the loop still located in my basement below ground. Read more
LZ1AQ Loop Amplifier – Breadboard Version
The LZ1AQ Loop Amplifier looks like a stable solution for my wideband magnetic loop project. Time to test a prototype on a breadboard. Read more
Head End Instability – LTSpice Limitations
LTSpice limitations can bite. The macro models used in simulation don’t sufficiently take into account parasitic and circuit layout effects that can haunt you down the road. Read more
