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…

NanoVNA Radio observation in hydrogen line (1420MHz)

A simple way to test an antenna with a NanoVNA

Admin May 14, 2025 No Comments

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…

Comments on using Leo Bodnar LBE-1421 to produce 1 PPS output

Planned ALAN Radio Telescope Field of View at 1420 MHz at Walsall Astronomy Group, UK

I see some people give times as eg 1200Z what does the Z mean?

The Leo Bodnar LBE-1421 provides a 1 PPS output that can be used as a long-term GPS timing reference, while allowing the FE-5650A rubidium oscillator to provide the very stable short-term frequency, in a combined time source
