Going for the Hydrogen Line

May 31st, 2020

I have been curious about everything about the hydrogen line for quite a while. So at least I mounted a feed for 1.4 GHz in my 3 m dish, installed a LNA at the feed, as well as a Pluto SDR and SDR# with the IF-Average plugin. First steps are very promising, as I saw something, when beaming to Cassiopeia and Swan.

Due to the doppler shifted signals the lines are smeared (red marks). The spikes seen, are just interferences.
