NanoVNA
Radio observation in hydrogen line (1420MHz)
Making a 2nd cantenna for the antenna testing range in the NanoVNA workshop at EUCARA 2025
In September 2025, EUCARA is being held at Harwell Campus in UK. I am giving a talk and also running an introductory workshop on using NanoVNAs to test antennae/aerials. As…
Linux Ubuntu for Radio Astronomy: Michiel Klaassen’s UKRAA CosmicWatch Muon Detector Data Analysis Python Script 16 May 2025
Michiel kindly wrote this script for me to help me analyse the data I have from my Muon Detectors – these are the Cosmic Watch Muon Detectors – I have…
Linux Ubuntu for Radio Astronomy: Plotting events from Muon_Data_110425@0116.txt data file from UKRAA Cosmic Watch Muon Detectors using Michiel Klaassen’s Python scripts 16/5/2025
I am surprised at just how many events there are in this file – which started 11/4/2025 : 01:16! Michiel has had difficulty converting the data into a format that…
Calculating the decibel gain from my Alex Pettit Patch Yagi Antenna (1420MHz) (LRO-H3) using data collected with ezCol from Easy Radio Astronomy Software
I used a screen recorder to record time-lapse of the ezCol screen over 24 hours then choose the frame with maximum gain demonstrated for hydrogen. Calculation of decibels involved: 20…

A simple way to test an antenna with a NanoVNA
A simple way to test an antenna with a NanoVNA involves connecting the antenna to the NanoVNA, calibrating the device using open, short, and load standards, and then measuring the…
UKRAA PicoMuon Muon Detector up and running
Thanks to Ted Cline who helped me get this up and running on Sunday evening. Now that it is going, it is a wonderful little machine – composed of 2…
First Light UKRAA PicoMuon Muon Detector
“Live” data from this detector at LRO can be viewed at www.astronomy.icu First light from 12/5/2025 @ 10:43, after the detector had been turned on for about 12 hours. Click…
