WSPR Propagation Reports Worldwide
WSPR propagation reports are really useful in checking ionospheric activity. Get started by using WSPR on OpenWebRX internet connected monitoring stations. Read more
VA6OK Remote Wideband Loop – My Benchmark
If you want a sense of how well magnetic antennas can perform, check out the VA6OK remote wideband loop for yourself. It’s one click away.

Loop Transmission Line Shielding
Proper connection of my CAT7 provides loop transmission line shielding for lower noise reception at my location. My loop now performs properly on lower HF and below. Read more
Initial Wideband Loop Testing
My initial wideband loop testing shows reasonable MW and Lower HF performance, but I need to address shielding and impedance matching to prevent the CAT7 from acting as an antenna. Read more
Magnetic Loop Compendium – Summary of Work
For the past five years I have experimented with magnetic loop antennas. I thought it was time to publish a magnetic loop compendium of my work, complete with links to all articles. Read more
Painting PEX Pipe – Options and Approaches
Painting PEX pipe gives your orange plastic loop antenna an aluminum appearance. I experimented with Krylon Fusion as well as ordinary 100% acrylic latex. Read more
Simpler Lighter PEX Wideband Loop
This week I created a simpler lighter PEX wideband loop. It has half the weight and better stability than my first version. Looks better, too. Read more
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
