I was just watching Titanic and spent 20 minutes looking up the effects of hypothermia and discovering that Jack may have been alive and in stage 3 hypothermia when Rose let go, and because he sank instead of floated, he was in fact alive. It was a fun little time sink. What rabbit holes have you done down recently?
It started with a pair of two-way walkies, talking with a friend in the backyard while sitting in my bed and then you're pointing to satellites and the ISS to download weather and old space images.
I love radio stuff, but I just haven't dove into Ham yet. That said there a local radio shack with their call signs posted on the window so I might just dig in.
Maybe find my excuse to actually use gnuradio for something.
