To use GNU Radio for radio interferometry with an SDRplay RSPduo
Admin
April 2026: The following is my attempt to work out logic for achieving a successful interferometry experiment. I use this blog as my lab notes, so some of the entries…

To use RSPUno for interferometry
To use RSPUno for interferometry, you’ll need to understand both the hardware configuration and the software/data processing workflow. RSPUno is a system derived from the Radio-SkyPipe software but optimized for…
Why a C-band scalar ring cannot be used for 1420MHz Hydrogen line radio work
Using a conical C-band ring on a 1420 MHz (L-band) cantenna is generally not advisable because of the large frequency mismatch, but let’s break it down in detail: 📡 Key Concepts…

To utilize SDRplay’s RSPduo for interferometry
To utilize SDRplay’s RSPduo for interferometry, you’ll need to configure the SDRuno software to receive and process signals from two separate antennas, then use its diversity reception features to combine…
