What is format used in data files produced by Radio Sky Pipe II Software?

Admin November 21, 2025 No Comments

Radio-SkyPipe II (R-SP) uses a binary proprietary file format for its data files. Here’s a breakdown of the format, based on the Radio-Sky documentation: File Format (Radio-SkyPipe II) Interpretation /…

USRP B210 Software-Defined Radio

I am using USRP B210. I have set bandwidth to 56MHz. Maximum available sample rate is 10MHz. If i use that then computer crashes due to data overload after a few samples. I have had to reduce sample rate to 2MHz to avoid crashing.

Admin November 21, 2025 No Comments

Thanks — that context makes the problem clear. Below I’ll explain why your computer crashes, show the data-rate math with ASCII equations, and give straight, actionable fixes you can try…

How does sample rate relate to frequency and bandwidth on SDR?

Admin November 21, 2025 No Comments

In an SDR, three related but distinct concepts often get mixed together: frequency, bandwidth, and sample rate. Here’s how they actually fit together: 1. Frequency (centre frequency) This is simply…

When ChatGPT writes out equations they look good but when I copy the chat they don’t copy well. How can this be resolved?

Admin November 20, 2025 No Comments

That happens because the chat interface renders equations nicely on-screen, but when copied, the raw Markdown or LaTeX comes through in a less readable form. Here are a few ways…

Radio observation in hydrogen line (1420MHz) Waveguides

Critical aspects of measurements when making a cantenna waveguide for radio astronomy. Extracts from SARA & BAA Radio Astronomy Group Mailing Lists 19/11/2025.

Admin November 19, 2025 No Comments

From Marcus D. Leech: Probe placement with regards to the distance from the back-short, probe length, and positioning of the waveguide at the proper dish<>feed spacing. That is, if you…

Radio observation in hydrogen line (1420MHz)

What is benefit of upgrading from 1m dish to 2.4m dish for hydrogen line?

Admin November 19, 2025 No Comments

This analysis is for a friend who has made this upgrade. The largest diameter dish we are currently using at LRO is 150cm dish made of 6 petals – soon…

How to change a normal Python‐level GNU Radio variable after the flowgraph has started

Admin November 18, 2025 No Comments

You can’t usually change a normal Python‐level GNU Radio variable after the flowgraph has started, but there are workarounds = you can make a variable externally adjustable while the script…
