A: FROM MENTOR CAROL TOMAN
IN IL
Your "atomic clock" is not really atomic at all.
It listens for a
radio signal from the real atomic clock in Fort Collins, CO.
and it
uses that signal to synchronize itself with official US timekeeping.
The atomic clock in Fort Collins was not affected by the hurricane.
My best guess is that a lot of new radio interference has
been
introduced since the hurricane in your area. Radio interference
is
commonly created by poor electrical connections which is
understandable if repair crews are hurriedly splicing together
wires
to restore service. Let's hope that they go back and make
improvements or your clocks could be permanently useless in
your
area. If you have a chance to travel, try taking the clock
with you
to see if it works in a different area (even a few blocks
might make
a difference). I've attached a paragraph that I lifted from
an
advertisement for an atomic clock which contains some ideas
for
further research.
"The national institute of Standard and Technology (NIST)
in Fort
Collins, Colorado broadcasts the time signal (WWVB at 60KHz
AM radio
signal) with an accuracy of 1 second per every 3,000 years.
Our
innovative timepieces incorporate a miniature antenna and
receiver
with Atomic technology to intercept the time signal broadcast
from the
U.S. atomic clock operated by the National Institute of Standards
and
TechnologyNIST (www.nist.gov).
The signal is receptable over a
distance up to 2,000 miles from the source. Like a typical
AM radio,
your Atomic timepiece will have trouble receiving the WWVB
signal in
places surrounded by heavy concrete, metal panel, and electronic
interference. ` To get the best performance of the Atomic
clock,
please install the clock nearer to a window and change directions
if
one direction does not work. "
And, you're right, the atomic clock has nothing to do with
Hedy
Lamar's clever patent. You can read more about her invention
