Cool, thanks!

Hi all,

One of the Youtube channels I subscribe to is Sixty Symbols. Yesterday, one of the video creators put a video on called "The Joy of Radio". It was great to see a university professor with the enthusiasm he had as a kid when he built his first crystal set. I know how this guy feels. I feel the same every time I make one and hear something even now in my late 60's.  

Thought I would share.................
