The following is an extract from the WVURAIL/gr-radio-astro Github repository giving installing instructions for this important pre-requisite needed to use DSPIRA GNU Radio GRC flow-graphs. I have also included instructions…
I am experiencing errors when I try to tun DSPIRA GRC (GNU Radio Companion) flow-graphs due to missing gr-radio_astro out-of-tree (OOT) module in my Windows GNU Radio installation. What is…
A stressed dish (or stressed-skin parabolic reflector) is a lightweight reflector design where the parabolic surface is formed by tension and stress in the materials, rather than machining a rigid…

Here’s a detailed comparison between the RTL‑SDR Blog V3 and RTL‑SDR Blog V4, along with practical implications (especially for your antenna-wire setup). If you like, I can summarise a “which…
In SDRconnect the controls for adjusting the dB scale / Y-axis (reference level, dB range) are under the “Primary SP display settings” section in the left panel. (SDRplay) Here’s exactly…
In SDRUno, the spectrum display’s Y-axis (dB range) can be adjusted so you can see more (or less) of the signal rather than just the top. Here’s how: 👉 In…
You actually have two completely separate RSPduo units, and you want to see both running in SDRuno simultaneously. 👍 Here’s how you can set that up: 🖥️ Running Two RSPduo…
After a nighttime of further investigation, I have got as far as managing to connect & select between two separate SDRplay RSPDuo devices in GNU Radio. The settings in GNU…
