[BC] Part 15, er ... parts

[Mark Durenberger]

Guess I should be a jail guest of the Sheriff of the Airwaves then, Harold. 
In the 60's we installed an old RCA 250-watt transmitter at the University 
of Minnesota and split it by coax to various dorms.  Coax and line-couplers 
do leak.

Problem was: If you Google-Earth the U of MN, you see buildings scattered 
all over the city.  We were "off-campus" for 90% of the runs between 
buildings :-))
