Draft process for getting URSP B210 Software-Defined Radio to work on Windows version of GNU Radio.
Admin
This is a draft document, and I cannot confirm it works – you also use it at your own risk! No indemnity provided. NB If it does not work for…
With the non-calibrated Spectrum Y scales of ezRA / GNU radio,, how can hardware performance be compared and changes evaluated ?
That is the plus for the SDR Sharp > IF Average Plug-in for SDR Sharp > H-Line 3D software sequence, because even if you don’t have an absolute power scale,…
Using USRP B210 SDR with GNU Radio Win10 revised 14/10/2025
Collated document I have put together, which I think might tell people how to do this……no promises! I got it working once, but twice might be too much to ask!!…
First output from SDRplay RSPduo GNU Radio based on modified DSPIRA GRC using small handheld Moxon aerial on aerial input 1 of 2 — 15/10/2025
This will not be Milky Way as inside and Doppler shift on the 1420 MHz line too big – about 190 km/s (calculated from the difference in frequency on plot…
Computer Monitors and 1420 MHz Radio Frequency Interference (RFI)
The short answer is: most computer monitors do not directly emit significant power at 1420 MHz, but they can produce harmonics, local oscillator leakage, or broadband RF noise that can…
How to install “.appimage” files in Linux Ubuntu
How to install “.appimage” files in Linux Ubuntu Yes, Linux; the Linux packages are distributed as an “.appimage” for 32-bit and 64-bit distributions, and should run across all major Linux…
Size of corner reflector and performance for hydrogen line observing
Good question, Andrew — short answer: yes, up to a point, a larger corner reflector will generally improve hydrogen line observing, but there are trade-offs. Here’s the breakdown: 1. Collecting…
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…
How to use 2 orthogonal monopoles with phasing cable on cantenna waveguide to improve signal reception
Two monopoles at 90 degrees in cantenna One connects to splitter immediately Two connects via coax either 1/4 wavelength or 5/4 wavelength (more practical length = 26.5cm x 66% (velocity…
High Z ant(enna) connector on SDRplay RSPduo.
From: A. C.Sent: 06 October 2025. Andrew, I was going to mention but I forgot, in the after RTOP meeting yesterday you asked what the High Z antenna connectors in…
