fixed my fluke.l monitor.
This evening I got mail today from Bob Mokia:
The problem is too much volts on CPU (8051F330D).
Must have diodes 1n4148 etc at D1 and D2. Drop cpu volts to 3.6volts.

Hi Gents,
Just received a few hours ago my new Fluke monitor and just right now making
the mods... I used 2SMD diode and the voltage on the CPU is 3,6 Volt.
hopefully will work properly..
Will report later on any problem.
Rgds Ernie.

There have been hardware papers every few years showing this and that about
the clocks. They obviously have access to some sort of database that lets them
generate the data. I guess the database is off limits to civilians.

Hi,
The civilians are also used by the timing laboratories. Both antennas
and receivers float by on the eRiver from time to time at very reasonable
prices. These are more often than Oncores available with a built in
(tight) PLL letting you lock the local GPS recevier clock to your freq
standard.

Hi:
I've added a photo of the component side of the 8051 PCB at:

J1-2 is connected directly to pin 6 of the uC which is also connected to
the output of the 78D05 regulator.
Have Fun,

So a tree is a physical object, its workings can be understood by
botanical analysis, but just how do you quantify its beauty in numbers
or equations then? And before you try to wriggle out of this, the
beauty of a tree is a physical artefact because it imbues a reaction
in the viewer.

Hi All:
New user / first post. I just picked up a Datachron 3650-133 GPS
Synchronized Time Code Generator to use as a timebase for my amateur
astronomy observatory. I've looked all over for a PDF of the manual and
can't find anything. Does anyone have a copy (paper or PDF) that they could
Is that Daughter-Board soldered in or plugged in ?
It looks like it's plugged into the connector but I can't
get it to budge and I really don't want to apply too much
force and wind up breaking it.
Thanks, Dick, W1KSZ

I believe it's soldered. I was able to do my mod using through-hold

This out-of-control thread has been a total waste of bandwidth
for some time now. I feel that I should be embarrassed for some
of the posters here because they appear to have no sense of

Hi
What do you want to test?
What do you want to do with the results?
What are you going to compare them against?
What range of measurements are you interested in?
The DMTD will look at two atomic clocks on the same frequency and the reference
drops out in the processing. Is that important
Time-Nuts,
There has been much discussion on this list about methods
of measuring short-term stability. I wanted to make the
list aware of a new paper describing a small DMTD system.
The system was developed by William Riley, author of
STABLE32, and is described in detail with schematics
and test
I think I have found the source of the integration issue. I've spent
some considerable time ploughing through as many sources of
descriptions on ADEV, AVAR and the tight-PLL method. I've even tried
looking for the infamous finite time interval integrator which seems
