[Vintage-Audio]V40#15- BIG Wire

Sat Dec 15 10:22:14 EST 2007

Bob, you are truly a piece of work! I doubt that any other teenage male in 
America did what you did! A brilliant idea and a way cool plan too. Too bad 
you did not hide the radio in a resident park 'bush' or some other growing 
plant and convince the teenage females that you were a eighth cousin fifty 
times removed from Merlin the Magician, (he actually did exist, although the 
truth and his legend ...), and were making the shrub receive radio signals!

The best I managed to do was hardwire intercom speakers I got when I built 
an Allied Radio Knight Kit intercom one Christmas and position them in 
several locations outside under the roof overhang. Anyone within fifty feet 
of the house could hear my music, weather reports and who knows what else.
