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
How It’s Made – SDRplay
Inquiring minds wonder how it’s made. You can learn a lot on You Tube, including the story of SDRplay hardware and software. Take a look. Read more
Loop Array Pattern Calculations
Using an Excel spreadsheet, I have created an easy way to visualize my loop array pattern as I change frequency and phasing in the dual channel SDR. Read more
Antenna Fun with Array Delay
Beamforming, or signal phasing with multiple antennas, means understanding array delay through the complete system. Here’s how it works. 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
SDRplay RSPduo Noise Canceller
Create an RSPduo noise canceller with a simple connection to noise probe antennas. Your results will match those of the ANC-4 or MFJ-1026. Read more
Reduce ADC Overload from Active Loop on HF
Some front end filtering helps you use wideband loops with wideband SDR receivers on HF while holding overload from nearby broadcasters at bay. Read more
SDR Medium Wave Performance
Let’s check out SDR medium wave performance with a variety of front end designs which all work differently and well, most of the time. Read more
