“Virgo” in radio astronomy most commonly refers to a software package for running and analysing small radio telescope data using SDRs (software-defined radios)—not a single instrument or observatory. It is…
Here are the actual chipsets inside both devices, stripped down to the essentials: 📡 RTL-SDR Blog V4 Uses: 👉 So the V4 is basically: R828D + RTL2832U This combination is…
It depends strongly on frequency (coax loss is frequency-dependent), but assuming you mean something in the VHF–UHF / radio astronomy range (e.g. ~1.4 GHz): To get ~6 dB over 25…
An FTP cable usually stands for Foiled Twisted Pair Ethernet cable. It is similar to ordinary Ethernet cable, but it has an additional foil shield wrapped around all four twisted…
My UKRAA PicoMuon detector stopped saving CSV data files on to the 64GB SD card plugged into it. I realised the SD needed to be re-formatted. The PicoMuon requires the…
In the Ubuntu file manager (usually Files (GNOME Files), also called Nautilus), Compress creates a single archive file containing the selected files and folders. It does not normally reduce the…
Solution and conclusions: After multiple tests, the conclusions are as follows: 1) In many Linux distributions (mine is Alamalinux 9), the default driver is rtl-sdr-v-0.6. With this driver, RTL-SDR-v3 works…
From the month data folder (sub-folder of “processed” on the Raspberry PI running the PicoMuon muon detector). https://www.astronomy.me.uk/wp-content/uploads/2026/07/month.zip
This issue has affected some files written to SD cards on two PicoMuon detectors: I attach some screenshots below from a short file as an example that shows the problem.…
Below is a single unified DuckDB instruction set combining both versions into one clean, consistent workflow for large radio astronomy event datasets. Assumes columns: Unified DuckDB Workflow for Large Radio…
