Ku-Band Interferometry
Admin
From the Society of Amateur Radio Astronomy Mailing List 12/12/2025: We operated a Ku-band interferometer with two 1.2-m dishes placed on a 10-m baseline in east-west direction. It is dismantled…

Using 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…
SDRplay RSPDuo & radio interferometry
Short answer — yes you can do radio interferometry with the SDRPlay RSPDuo software defined radio, but with caveats. Downloads to go with this post mentioned in text below: https://www.astronomy.me.uk/wp-content/uploads/2025/09/sdrplay_windows_package.zip…
Is a shared clock required for interferometry with two software-defined radios, one per receiver?
Short answer: it depends on how you plan to combine the two channels: Practical options for your setup What to do based on your goal Why is a shared clock…
Open Source Tools / Libraries for interferometry
There are several open-source software tools and libraries for interferometry / correlator / radio astronomy work. Depending on how much of the pipeline you want (just correlation, calibration + imaging,…
Concrete examples of small-scale / home interferometry projects & designing system based on SDRPlay Duo software-defined radio.
Some concrete examples of small-scale / home interferometry projects that use open-source software, so you can see how people have actually tied the pieces together. Here are some examples you…
