Radio observation in hydrogen line (1420MHz)

Software defined radio. 1420MHz filter. Ptarmigan Triffid military phased array antenna (86cm x 86cm) http://astronomy.me.uk/wp-content/uploads/2023/10/SDRSharpIFAvg_Data-051023.zip

Now got 5 days of data – day 3 not synchronised with rest – I think due to my changing

After my previous posts in which I have very excitedly described my recent successes observing Milky Way at 1420MHz, I

My drift scan has now reached 3 days – the repeated high signal of Milky Way can be seen in

On the plot below, the bright orange areas indicate when high signal has been detected, and green dots represent my

Plots from ezRA suite:

At last! Pretty sure I have now managed to transfer my data to ezRA suite to produce some nifty plots!

Photos below show my attempt today to mount the array so that I can aim at Zenith and vary altitude

I successfully detected hydrogen for first time using SDR, hydrogen HNA, pre-amp, DC block, and SDR# (using version of SDR#
