Some observers trying to measure the speed of light using two separating Cosmic Watch muon detectors have come up with results faster than speed of light. Are these results possible?

Admin April 20, 2026 No Comments

Short answer: no—those experiments are not actually measuring anything travelling faster than light. When Cosmic Watch–style muon setups give “superluminal” results, it’s almost always due to measurement/systematic effects rather than…

Radio observation in hydrogen line (1420MHz)

Is there any benefit to using any other type of feed other than cantenna or loop feed for a small amateur radio astronomy dish for hydrogen line work & is there any benefit to adding a sleeve balun on Loop Feed?

Admin April 20, 2026 No Comments

Does this mean in practice that there is no practical reason to need any other type of feed other than cantenna or loop feed for a small amateur radio astronomy…

On qorvo low-noise amplifier PCB, three inputs VPD, GND, and VDD – what are these?

Admin April 19, 2026 No Comments

On a Qorvo PCB/module, pins labeled VDD, GND, and VPD are standard power/control connections, but each has a specific role: 1. VDD (Supply Voltage) 2. GND (Ground) 3. VPD (Power-Down…

What is the easiest way to check disk space on my headless Raspberry PI 4B and automate checks and disc space management for radio astronomy?

Admin April 18, 2026 No Comments

On a headless Raspberry Pi, the simplest way is just via SSH and a couple of built-in Linux commands—no GUI needed. Quick & easiest (recommended) Run: You’ll get something like:…
