Yep, as the director of a small observatory, I’m adding an antenna and a display of sdrsharp to hopefully show off radio emissions from our popular targets for public outreach. I’m sure most visitors won’t care, but I hope to snag that 1 kid and feed his/her curiosity.
I would care! I find non-terrestrial radio emissions interesting and would instantly recognize a waterfall display and be eager to explain to my companions.
