Andrew, if you Really want to do this you need to be Meticulous in Matching and Verifying Each feed system. It takes time & effort. 1) You MUST use software…
The screenshot below shows data collection on ezCol from both LRO-H2 Monopole 1 and LRO-H2 Monopole 2 (2 orthogonal polarisations on same cantenna waveguide on same 150cm parabolic reflector used…
At last! Go this 2nd monopole installed on the cantenna at 90 degrees to first – so now I can collect vertically and horizontally polarised 1420 MHz data – given…
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…
Ted Cline who has written ezRA has now added a new feature which gives users the ability to limit data used in analyses to a narrow range +/- near galactic…
A ready-to-run GNU Radio Companion flowgraph + Python calibration script, tuned for 1420 MHz hydrogen line work.

A practical recipe for successfully improving signal detection using two orthogonal monopoles in a cantenna. Great — here’s a practical recipe you can use with your setup (2 orthogonal probes,…
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…
I tried adding second monopole onto 1420 MHz cantenna at 90 degrees to first monopole in attempt to improve signal, with 1.5 wavelength phasing cable on one monopole. I used…
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,…
