Loop Prototype Learnings during Summer
My loop prototype learnings this summer are mainly about waterproofing and reducing intermittent performance. It’s time to move on to the final build. Read more
Sound Card Radio – Our First ADC
Recently, Guy Atkins mentioned his first software defined radio receiver, the FlexRadio SDR-1000. In particular, he mused about trying to get this gear to work with different PC sound cards. Read more
Guy Atkins Perseus Recollections
Guy Atkins Perseus activities became well known to the DX community in 2008. Recently, I asked Guy to provide some recollections about this wonderful receiver. Read more
Perseus SDR Benchmark – 11 Years On
I have been using my Perseus SDR Benchmark for 11 years. It remains a great performer for reception below 30 MHz and my “go to” receiver. Read more
Apollo 11 Radio Communications Remembered
It’s been fifty years. Let’s recall Apollo 11 radio communications systems, including the wonderful Unified S Band and local VHF that really worked. Read more
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
