My dashboard for my Cosmic Watch Muon Detectors is now finished – and the choice of graphs available. Go to https://cosmicwatch.astronomy.me.uk This has been created using Miguel Ríos Martín’s instructions…
Several software packages and algorithms are used to convert radio interferometer readings into images, with the most common being the “CLEAN” family of algorithms and the Common Astronomy Software Applications…
(This is separate from my PicoMuon Detector). This new domain URL below provides access to data dashboard from the 2 older detectors (click on link): https://cosmicwatch.astronomy.me.uk Please feel free to…

The TinySA and NanoVNA are both compact, affordable test instruments used in radio frequency (RF) and electronics work, but they serve different primary purposes: 🔍 TinySA (Tiny Spectrum Analyzer) Purpose:A…
Evidence for dark matter comes from multiple, independent lines of observation across astrophysics and cosmology. Here are the main ones: 1. Galaxy Rotation Curves 2. Gravitational Lensing 3. Cosmic Microwave…
Reducing noise in a 1420 MHz radio telescope setup (i.e., for detecting the hydrogen line) involves addressing both internal and external sources of interference. Here are the most effective steps…
If I use a filter at 1420 MHz that causes 3 dB loss and in amplifier beforehand that gives 3dB gain, will that cancel it out? Not exactly — a…
A long Yagi antenna tuned for 1430 MHz can still work at 1420 MHz, but with reduced efficiency and some detuning effects. Here’s a breakdown of what you can expect:…
