[Dixielandjazz] Xtal set

[Larry Walton Entertainment - St. Louis]

50 miles on a good night and with a good antenna was about the maximum 
distance.  The signals would have been faint in any case and of course hope 
there was only one station or two.

FYI there is a Crystal Set association that  is on line.  I believe they 
publish a newsletter too.

When I was teaching Ham Radio classes I used a crystal set and the 
electronic principles behind their operation.  There is absolutely huge 
theory that can be taught using one since about every basic part of radio 
operation is there.

When I was a kid I built many of them.  I also built one for my daughter. 
She helped.  We still have it and it still works.  She still talks about it 
occasionally.

How many electronic devices or anything else for that matter can a kid make 
today that will work, cost almost nothing, won't pollute, doesn't need 
batteries AND let them hear jazz (maybe).
