What is dedispersion in radio astronomy signal processing?
Dedispersion is a signal-processing technique used in radio astronomy to correct for the effect of interstellar dispersion—the way radio waves get “smeared out” as they travel through space. 🌌 What…
What is next size up antenna rotator from Yaesu G-5500VDC?
Got it — you mean the next size up from the Yaesu G-5500DC antenna rotator. Short answer: there is no direct “next model up” that is the same type. Moving…
What is load capacity of Yaesu G-5500VDC antenna rotator?
The Yaesu G-5500DC doesn’t have a single simple “load capacity” like a crane or mount — Yaesu specifies it using several related limits. The key figures are: ✅ Primary load…
The satellite mount that is part of the TV1 Minimaster system, how much weight can it carry?
Short answer: there’s no clearly published “official” payload figure for the TV1 Minimaster mount itself—but you can still estimate it fairly reliably from comparable hardware and its intended use. What…
Is there any digital inclinometer with USB connection?
Yes — but there’s an important distinction that matters for your use case: 👉 Most cheap USB inclinometer devices are USB-rechargeable only (power),👉 Very few actually output angle data over…
Is there a self contained telescope pointing device that can fit on any telescope to point it to a star?
Yes — there are self-contained telescope pointing systems, but they come in a few different flavours depending on how “universal” and “self-contained” you want. The key term to look for…
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…
