Easy Radio Astronomy Software (ezRA) LRO-H2 Radio Telescope (150cm Solar Cooker Dish) SDRplay RSPduo Software-Defined Radio (SDR)

GNU Radio Companion GRC file used for test of alternative to ezCol with SDRplay RSPduo for data collection for later analysis by ezRA on LRO-H2 radio telescope 16/10/2025

Admin October 16, 2025 No Comments

I am just about to use the following file on the Solar Cooker Radio Telescope (LRO-H2) as part of a test of a system to collect data in ezCol .txt…

GNU Radio Windows

Draft process for getting URSP B210 Software-Defined Radio to work on Windows version of GNU Radio.

Admin October 15, 2025 No Comments

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…

Easy Radio Astronomy Software (ezRA) GNU Radio

With the non-calibrated Spectrum Y scales of ezRA / GNU radio,, how can hardware performance be compared and changes evaluated ?

Admin October 15, 2025 No Comments

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,…

USRP B210 Software-Defined Radio

Using USRP B210 SDR with GNU Radio Win10 revised 14/10/2025

Admin October 15, 2025 No Comments

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!!…

SDRplay RSPduo Software-Defined Radio (SDR)

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

Admin October 15, 2025 No Comments

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…

Radio observation in hydrogen line (1420MHz)

Computer Monitors and 1420 MHz Radio Frequency Interference (RFI)

Admin October 15, 2025 No Comments

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

Admin October 15, 2025 No Comments

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…

Radio observation in hydrogen line (1420MHz)

Size of corner reflector and performance for hydrogen line observing

Admin October 12, 2025 No Comments

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…

Radio Interferometry

Using RSPUno for interferometry

Admin October 12, 2025 No Comments

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…

If EQ6 mount is being controlled from Stellarium via ASCOM driver, then if I point the telescope at an object, then turn off the mount, and later turn the mount back on, will ASCOM be able to re-establish pointing position of mount?

IEXOS 100 mount – can you turn off tracking – ie use it to point but without powered tracking as tracking causing RFI?
