You can easily combine configurable SDR devices with open source software to build and operate virtually any wireless protocol and modulation scheme. Let’s take a look. Read more
SDR FPGA – Moving Beyond the Blank Stare
Talking about SDR FPGA typically earns you a blank stare. Let’s move beyond that and consider the power unleashed by Field Programmable Gate Arrays. Read more
Modern SDR Architecture with Programmable Hardware
Put down your soldering iron. Build your next receiver using your keyboard. Modern SDR architecture makes this (almost) possible. Read more
SDR Programmable Hardware Paradigm
Ironically, SDR programmable hardware has really brought software defined radio to the next level. In this series, we’ll explore how this is done. And how you can do it yourself. Read more
Shack Noise Floor – Spring Cleaning
At least once a year, you should do a complete cleanup to make sure you have not introduced new sources of RFI in the radio shack. Here’s how to sweep the shack noise floor. Read more
AFE822x Coherent RFI Filtering Performance
My AFE822x coherent RFI filtering goal has been accomplished. Every SDR should be capable of spatial interference filtering techniques. Read more
Heading Home from Asia – Fog Delays
Foggy days and airline confusion made heading home from our Asian cruise challenging. Our biggest challenge was the Air Canada counter at Shanghai airport. Read more
