Hi all, I'm new here (been reading for a while, but this is my first reply) so
sorry if I'm not doing this reply thing right. There is a Spirent simulator
down the hall from me that I tested the output PPS on a few months ago using an
Agilent 53230A (OCXO option). While I don't remember the exac
Thank you to all of the respondents. There is a lot of great information in
the replies. Based on more interaction with our customer it's looking like we
may need to send the unit(s) out to a facility that specializes in this area.
Best regards,
John

Sorry if this is an FAQ...
Has anything else happened with the WWVB BPSK change since the test in March?
Also, I would love to correspond with anyone who has worked with the
C-MAX CME-8000 boards.
Thanks! I'm looking forward to participating.

Welcome to the list. There have been numbers of tests since March.
Ultimately a more detailed specification was released thats been helpful in
understanding the new modulation.
In various threads I have mentioned what I have been doing. At the moment

Hi!
At this point I'm mostly just trying to learn about the new signal. I
play around with microcontrollers and have always wanted to build a
WWVB clock. I spent a good amount of time with the CME-8000 board
before getting frustrated with it and putting it aside for awhile. I

Hi
Based on a quick look - the CME8000 isn't going to be much of a help with
the new modulation. It will do ok with the old AM format.

Right. I know that. I should have said that I'm going to abandon the
CME-8000 solution in favor of BPSK assuming they actually implement
it.

Bob exactly good for the am and sort of a front end but completely stops
being useful at that point. But still getting from 10 uv to a 1/2V thats
not all bad for a drop of glue.

I suspect they will so hunt wwvb for the new bpsk doc it will be helpful.
This ain't your old AM approach.

Fellow time-nuts,
Yesterday I picked up a Sulzer 5A + 5P without batteries. It is supposed
to have 21 D-cell NiCd batteries, but today those are not easy to come
by, so I wonder if I can either run the PSU safely without battery or if
I can swap in lead-batteries.

for the various types of batteries on the market. So many freq standards have
outdated battery technology. It would be nice to find an modern alternative
battery that does not require much modification to t

A rare occasion that I get to have an answer for you.
I have two sulzers also and the batteries 5 years ago were an issue.
I believe nimh batteries could be put in if you really need batteries. At
$35 I passed that option. Plus batteries are just a pain.
I think the issue you have is that wi
Nimh is indeed the answer to replacing nicads but they are not inexpensive.
The other thing is that the energy densities have gone up over the years so
you can use a smaller footprint. But you have to check the charge rates.
Typically .1c for slow.
I have old nicads from HP that indeed still work

I have used NiMH D cells as directly replacements for NiCd D cells in
devices that have slow, 0.1C rate or 14 hour, chargers without
problems. It takes longer to fully charge since the NiMH cells have
about twice the capacity but then they last about twice as long.
The price for the MiMH cells is
Hi Magnus,
that should be pretty much identical to my recently acquired Racal MA259

The batteries have already been replaced by a 'battery simulator'. I
haven't looked inside yet, but it consists very likely jus
Hi Magnus -- I was recently (within the last year) able to get the battery pack
in my 5P power supply rebuilt by the local Batteries Plus store. It took a few
weeks for them to order and obtain the cells, but they do seem to be available.

Hi Magnus;
I know I am stating the obvious but the batteries with no external power
provides by far the lowest noise. And if that is desired NiMh have a much
better discharge characteristic then NiCd. But there is something to be said
for maintaining the oscillator in factory original condition

I have a local shop that builds battery packs that turn out to be cheaper
than Batteries Plus since shipping is not involved. You should check your
local yellow pages to see if you have a 'Battery Warehouse' type store.

No idea. The fact that the gps rcvr is a fumoro most likely makes none of
the software we have usable. They typically use motorola rcvrs.
Its also $90 shipping.
So for $180 I would spend a bit more and get a Tbolt and have some useful
control software.
Good luck
