Thanks Tom and Bob, I have been thinking of contacting Agilent for some time.
I think they are a great company with some good products, but there are a few
real blind spots in some current products. I also have seen in the past a

Mike,
They are already giving you another way to calibrate the unit, different from
how you think they should have done it and you are pulling out the statist card
and accusing them of being greedy capitalists?
Come on, thats backseat driving. Be happy they invested millions of their own
That was a wink, Said, not a howl...

I hope I have not come off sounding like that Said, I simply would like to see
a great product better, I am hoping/committed to work with Agilent toward a
better product if they are interested. And in the past I have found they are
interested in our feedback. The 53132A was revolutionary in
Hi Bruce,
What are the tradeoffs with using different values for R1? I have no practical
experience at this, so all I can do is rely on the models. Does the fact that
R2 is in the PIC, and C1 is so tiny, make the value of R1 of less importance?
On my PIC, they list C1 as 5pf, R2 as
Hi:
In the video about the Full Moon Curse (that's about measuring the distance to each of the 5 retro-reflectors on the
moon to 1 mm) there's a plot showing the elevation change in the Apache Point Observatory of about 20 inches peak to
peak. It's exactly the type of change the effects

I wonder if NIST has one of the GWR gravitymeters on a pier and uses that to
discipline their fountain clocks for the elevation change of the pier or if
that's done for the GPS reference antennas?

Sorry early morning rant,
There are counters out there already that can do 14/15 digits: tsc5125A and the
Miles box for example. Very difficult to get a reference into that counter that
can match and provide that type of stability.
I am sure Agilent would love to hear our feedback probably as

It may be true that WWVB is sending out a new
format, but the receivers for it don't seem to
exist. The exclusive rights are held by this
company, which is clearly on hold while it

Can anyone recommend a atomic wall clock
that displays in digital 24 hour UTC? Looking for largest
possible digits and LED preferred over LCD, under $100.
Any brands to avoid?

They implement a new format which destroys much of the installed
infrastructure, then don't actually produce the 'better replacement'.
How very LORAN!

Most of the atomic WWVB clocks cannot be set to zero time zone offset.
After considerable looking, I found one that can be set to GMT with DST
disabled. Look for this one:

Model WS-8016U
It also has local and RF remote temperature.
I got mine at Fry's Electronics, several
LaCrosse 8055 is one of the few wall clocks I know that allows UTC time
zone to be selected.
BTW, I have a Casio Waveceptor watch (the cheap $30 one) and it works
excellently, always acquiring WWVB signal at midnight to 2 AM here on East
Coast.

Definitely avoid BRG clocks. They are reasonably priced and look really
nice on the outside but look like a high school science project inside.
Plus, with both versions I purchased (while at 2 different companies),
the IRIG-B option just didn't work reliably. It worked some of the
time,
I recently bought a La Crosse, See at ebay item 360752857574, that quickly
