[Milsurplus] "Receiver Radiation, Oh No! "

[Tom Norris]

Back in the days when cars had points, sparkplug cables were copper and most folks didn't run
resistor plugs, I was always able to tell when the mailman was nearby. We could hear his ignition 
from DC to daylight - usually on MWBCB first, then when he was a couple houses away, could see 
the pulses on the TV thru about channel 5.  We were a good 60 miles away from all but one TV 
transmitter -- channels 2,4,5,8 were in Nashville, 13 was in Bowling Green KY - about 10 miles away.  
Never *did* see any sparklies on chan 13's video, though. (thank goodness) I'm sure it would have 
taken a heck of a spark to make it up that high.

Most of the largish heavy/useless/surplus stuff I ordered back then came via UPS (Fair Radio Sales,
Meshna, B&G and others) so there wasn't much of a warning since they ran diesel vans. Pieces parts 
usually came parcel post, so I was always waiting for bits and bobs in an attempt to put together the 
latest Popular Electronics project.  I never had to be sent to my room as punishment when I was a 
kid -- I had a radio bench, electronics bench, TV, books, comics, etc so I rarely LEFT my room back
in the 70's.
