Radio observation in hydrogen line (1420MHz)

Ideal thickness for copper feed for cantenna at 1420 Mhz

Admin May 24, 2025 No Comments

The ideal thickness (gauge) of copper wire for the feed in a cantenna (typically for Wi-Fi at 2.4 GHz) depends on both practical and theoretical factors, mainly skin depth, mechanical…

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…

LRO-H3 Radio Telescope (Alex Pettit H-Line Yagi) Radio observation in hydrogen line (1420MHz)

Calculating the decibel gain from my Alex Pettit Patch Yagi Antenna (1420MHz) (LRO-H3) using data collected with ezCol from Easy Radio Astronomy Software

Admin May 16, 2025 No Comments

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…

What is the easiest way to check disk space on my headless Raspberry PI 4B and automate checks and disc space management for radio astronomy?

I have installed baobab on my Raspberry PI 4B but not working.

I have used active@ disc imager to save image of my 64gb ad card from my Raspberry PI 4B. I then used the use in active@ disc imager to burn a new copy of the image on a space unused 128gb sd card I had. I was hoping to increase available capacity on sd card. The new card does not work.
