As a C.E.T., with what used to be a 1st phone ticket until the commission
threw us under the bus, with an 8th grade education who has been lassoing
electrons to make them do useful work for the last 65 years, I have been
nailed several times, but each time he indicated he was not ready for me.
Once was pretty bad, put me horizontal with the shingles for about a
month.
Quite used to the safety precautions associated with high voltage power
supplies of the sort that can supply 20 kilovolts at a few hundred amps
under near short circuit conditions where the normal load is in the 10 amp
range. Those can bump your lights from all the way across a town of
300,000. They have been my play toys for the 50 some years that I have in
as a broadcast engineer, with the last 18.75 years I worked, as the CE at
the tv station I use for an address.
I am in my element at a tv station where 3 or 4 papered & well paid EE's
are telling me it can't be done, until I push the button and it Just
Works(TM). I love the sound of jaws hitting the floor when they realize
their education has been sadly lacking in teaching them the physics
involved with this stuff. Being tested at 147 on the Iowa test 68+ years
ago hasn't hurt either. :) I was also blessed with a mother who was the
only girl in the Aviation Technology class at Des Moines Tech High in
1929. If she didn't know the answer, she did know where the library was,
so I was reading high school physics books at the same time I was bored
because I also had to do McGuffy's Readers in a little country school at
the same time.
Now? I'm just an old fart, trying to stay current. Many Thanks for the
flowers.
