Certificated Time Nut (Clive Green) certainly a wavemeter should count, so
should Lecher Lines, not sure about a calibrated candle or sun dial (maybe
if its very nice) but not hour glass / egg timer. Really well aged tuning
fork mmmm OK but not the bowl of water with a hole in it gismo. If GPS or Rb
are to be the lowest these very important steps certainly drop off the
bottom.

Hi John,
         Ok. Great idea.  We should make up a certificate that looks
like an NIST cert. that certifies that if we have a working
Cesium  or hydrogen maser standard or two or more standards that can
be traceable to NIST, you can become a Certified  Time Nut. It will
look nice hanging over a person's maser.
          Of course we could have levels as well. Master Nut (Own a
maser or 5071) and then levels like primary, secondary and tertiary.
The lowest could be  having just a GPS source or rubidium.  What do
you think? Maybe we could come up with something interesting. Anyone
want to make them up?
         Doug

You really need to get Borgmans permission to include the
Zits nanosecond strip on the certificate.

Well I have been to NIST in Boulder so maybe I am certifiable (probably).

Doug you might check
http://cp.literature.agilent.com/litweb/pdf/08642-90224.pdf for a copy of
the operating and calibration manual for the 8642A. There are probably some
other sources of free manuals on the internet. I have had problems with the
various Agilent servers of late, so be patient if you can?t get in to their
sites. Another source for a manual on your instrument is
www.yourmanualsource.com near Baltimore. They charge $25.00 per week but
have been a good source for me in the past. When I rent from them I scan the
whole manual. Good luck.

whats this lesser standard in the gps and rubidium stuff.  i have a hp 117a
tracking receiver that prints days with straight lines from my rubidium osc.
also three hp 59309a clocks that say i have the correct time for weeks
running from the standard.  hope that makes me at least in the middle of the
good guys.  maybe you could leave the space and i can fill it in myself with
little flowers and some funny faces..........

If your 117A, listening to WWVB, draws straight lines
then something is wrong with it. You should see a change
between day and night.

Ah, unless you live near Fort Collins, CO.

A flat line isn't always good news. There should
be a nice little phase bumps every hour. Do your
117A charts look sort of like the ones below?

Hi Mike --

I still haven't found any documentation, but I dissected the battery
pack and it uses 12 "F" cells (1.2 volt, 7000maH) in series.  I got
replacements from my local Batteries Plus and the new pack seems to work
fine.

looking at the trace it has the deflections from wwvb in 1 hour segments and
at dawn and dusk the shift appears as it should.  after days of charting the
average trend is close to a straight line and if turned off for weeks it
comes back up with the same drift rate .   the standard has been on for over
a year and seems to be stable.  using it as a reference to a sdr-1000
digital radio and on the 25cycle filter all wwv freqs come up on the peak as
it should.  i guess that means it is pretty close or close as i want it for
my use.   no it isnt a straight line continous , was using the average
reading with a ruler on the graph.  hope that cleans up my mistake.  think
that puts it in a better than low class........
