Here’s what I found on the sampling / time resolution (“sample time”) and timing behaviour of the CosmicWatch muon detector: Key timing / sampling facts Summary & caveats So, in…
That’s a neat question — it sounds a bit counter-intuitive at first! https://www.astronomy.me.uk/wp-content/uploads/2025/10/1000036614-161025.png Here’s why a corner reflector antenna doesn’t just bounce the hydrogen-line radio waves back out into space,…
Yes — the dimensions of a horn antenna really matter for hydrogen line (1420 MHz, λ ≈ 21 cm) observing. The horn’s shape sets its gain, beamwidth, and impedance match,…
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…
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…
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,…
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!!…
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…
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 Yes, Linux; the Linux packages are distributed as an “.appimage” for 32-bit and 64-bit distributions, and should run across all major Linux…
