Hi Andrew I have attached two files (accessible via link at bottom of this post), which need to be copied onto the RPi. I have changed their names because a…
Sketch a practical 20 kHz tuning arrangement (variometer vs switched L/C vs active front-end) tailored to radio astronomy
At 20 kHz you’re really designing a resonant system, not just adding a tuner box. For your kind of radio astronomy / interferometry work, the most practical approach is a…
How to optimise focal position of Brian Colemans Hydrogen-Line feed on LRO-H2(Solar Cooker 150cm RT)–19/3/2026.
From Brian Coleman: Hello Andrew, Looking at your photo the feed looks much too close to the dish. You need to calculate the focus point of the dish. The phase…
Is central obstruction by feed important on hydrogen line dish?
Yes—central obstruction from your feed does matter for a hydrogen line (1420 MHz) dish, but how much it matters depends on your goals and geometry. What central obstruction does When…
Masers seem to be from small molecules eg H2O – can you get them from e.g. long chain hydrocarbon?
In principle yes, but in practice it’s very unlikely—and that’s why nearly all known astrophysical masers come from small, simple molecules. Why small molecules dominate masers Most astronomical masers involve…
What limit does Cosmic Watch muon detector use to include an event on the two coincidence detectors as being detected?
For CosmicWatch in hardware coincidence mode, the criterion is actually very simple and quite tight: Hardware coincidence (detector-to-detector cable) 👉 So the effective “limit” is: Two pulses must occur within…
