Watching my new SDR's waterfall is so neat.
After I listen/watch, when I close my eyes I see waterfalls of AM transmissions. They're pretty well defined. And then in the morning before any radio, I've seen perfectly vertical lines a couple times when I close my eyes. I think I need to arrange the signals horizontally so I can give my eyes/brain a thorough work out.
So yesterday, I was outside and my eyes were drawn to a jet's contrail with the notion it was a signal on a waterfall!
I even used a new phrase the other day, "I'm going to go watch my radio."
Does this happen to anybody else?
