My friends have inspired me to build a radio astronomy telescope in the range of the resonate frequency of hydrogen, 1.42 GHz and have it designed it to actually listen to the frequencies in that range. There are several videos on RU-vid about amateur astronomers measuring the hydrogen clouds throughout the galaxy but I have not found one yet, that has audio of these frequencies. I am using a SDRPlay (software defined radio) along with its native software, SDRUno that is a common item in many amateur (ham) radio stations. I hope we find something. I am attempting to "hear" the moon, the sun, and the stars. If you have knowledge of this technology, please comment to bring forward advanced knowledge of the subject. The last thing I believe I may need to do is use a bandpass filter to lower the noise floor as I can find no information on the relative amplitude of resonate hydrogen in the universe from Earth perspective. At the present time my noise floor is -100 dBm but I am not sure that is sufficient. We also hope to communicate in a peaceful manner with ET. :-)
