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…

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…
The key part of the error is: UnsupportedClassVersionError ...has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime…
Hi Andy, Good to see you got the program running, at least on one file. Interesting that, for the top and bottom detectors, the measured standard deviations are lower than…
For a portable picoMuon detector it may be helpful to reduce the amount of data recorded. By changing events_all=True to False only coincident events will be written to the sd…
In our discussion today regarding the use in N.A. of DTV station signals for meteor scatter illumination, in lieu of the lack of similar signals as the French GRAVES or…
