HF Coastal Radar – Over the Horizon
You can easily receive HF coastal radar signals on your SDR, and sometimes even read the radar return signal under the right conditions. Read more
Configurable SDR Devices – Broadband Transceivers
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
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
AFE822x Diversity Receiver with PowerSDR
You can set up an AFE822x Diversity Receiver with PowerSDR for under US$400. Great value and performance to get started in SDR spatial filtering. Read more
AFE822x Single Channel SDR Software
SDR-Console is probably the best AFE822x single channel SDR software. It works well over a USB, Network Server or direct Ethernet connection. Read more
Afedri SDR-Net First Contact with HDSDR
My suggestion is to make your Afedri SDR-Net first contact with HDSDR. This popular software radio program is included in the box on your Afedri CD. Read more
