Radio observation in hydrogen line (1420MHz)

Results of two day drift scan of Milky Way at 1420MHz (hydrogen line) using SDR, HNA and Phased Array.

Admin October 2, 2023 No Comments

On the plot below, the bright orange areas indicate when high signal has been detected, and green dots represent my signal detection. Aerial was aimed at Zenith. In the graphs…

Plotting hydrogen of Milky Way

Admin October 1, 2023 No Comments

At last! Pretty sure I have now managed to transfer my data to ezRA suite to produce some nifty plots! Waiting for Ted Cline from SARA to confirm – but…

Two lessons I have learnt about practical aspects of radio-astronomy

Admin September 25, 2023 No Comments

Two important lessons I have learnt over last week,.by making these errors:

Radio observation in hydrogen line (1420MHz)

Mounting the Ptarmigan Triffid Military Phased Array to allow altitude to be varied.

Admin September 22, 2023 No Comments

Photos below show my attempt today to mount the array so that I can aim at Zenith and vary altitude between horizon and Zenith. I have yet to try it…

Successful detection of galactic atomic hydrogen in Milky Way using Ptarmigan Triffid Military Phased Array 21-22/9/23 in Lichfield, UK

Admin September 22, 2023 No Comments

I successfully detected hydrogen for first time using SDR, hydrogen HNA, pre-amp, DC block, and SDR# (using version of SDR# software provided in SARA Scope in a Box software package).…

Ptarmigan Triffid Military Phased Array Sept 2023

Admin September 20, 2023 1 Comment

I have been given this incredible aerial/antenna this month – it a military phased array tuned to roughly the correct wavelength for hydrogen (1420MHz) with (I am told) a resolution…
