We are using Wenzel with two filters see attached if it will pass. 20 Mhz
is down more than 60 db and 5 MHz 55. Distribution Amp takes care of the
rest.

Hi Paul,
I haven't used the Starloc II, so can't offer any direct help/advice, but
I did find manuals for the Starloc II and Starloc II plus when searching
for Starloc-Lite data a few years ago.
As always I hoarded what I found, which makes this your lucky day rather
than mine as I
I would like a copy of the article please.

Hi Ignacio
I'm sure removing the oscillator would make your faultfinding much more
straightforward.
When I removed mine I started out quite convinced I wouldn't be able to do
it, even with the solder mostly removed from around the pins they were
obviously quite a tight fit and all I had
Hi all,
I can suggest a different solution I have tested to have some important
improvement. First, the lower phase shift sensitivity with the use of a low
pass filter in conjunction with two notch filters instead the high Q band pass
filter, second the unity gain to avoid a 13/20 dB
Luciano,
This looks very nice. However, the inductors are
custom made. It would be nice to have a
off the shelf parts solution so it can be made
easily.
Any ideas ?

Hi Skip,
Seeing as how you have spent some time poking around inside FE-5680s
maybe you might be able to help with a problem I have with one. A while
back I purchased two 5380As that where reputed to be new they are marked
with 10MHZ OPTION 57 and would seem to match you description of the

On the older units that used a RB to control an Xtal. They created a mix of
5 Mhz +10 Mhz and that produced 15 out that hit an amplifier to drive a 12
way splitter.
I think I reverse engineered the circuit. Its on paper and filed. Oh that
ends this discussion.
Anyhow it was not hard to figure out.
Hi
How much is your unit moving?

Hello Nigel,
Finally I got enough courage and removed the OCXO, you know what kind of
task it is.. Fortunately I didn't spoiled the PCB so I'll install 2 smb
connectors in the provided places, I don't want to return there if I
need to change the oscillator.
Well, the oscillator is ok, this
Bob the actual pictures and files are large so here is the left screen and
right screen from the z3811 program. Pretty easy to guess whats in the
middle.
Lots of noise on the ti/pps and you can see EFC is rising all the time.
I will say in the past it had been a steady rise now there is a wave

A classical tv anyplace? 4th harmonic of the flyback was a common issue.
My best guess and highly doubtful.

Hi Perrier,
Thanks, I would like the documents.
I have a HP 3586B and its sensitivity is right on for the 20 Hz and 400 Hz
bands but is about 30 dB low for the 3100 Hz band.
I have manuals but have not found the fault. Do you have suggestions?

Hello to the group.
Running the Lucent GPSDO and its been on for 5 days now.
This is a capture from the z3811 program.
I did not think I could get this graph out to time nuts. The actual files
are quite large. However a .png makes it pretty compact.
My question Is this normal? I did not expect
Maybe it's leakage from another time-nut's experiment in the
neighborhood, or some commercial equipment. There's probably lots of
stuff going on in that area. It's not necessarily a broadcast
carrier, but just a frequency that happens to be generated somewhere
and getting out big enough -

According to the plot, the oscillator is still
7.6 Hz is very close to the Schumann resonance fundamental.

A solar system power inverter?
A generator control panel?

George,
you can replace the input transformer with the mini-circuits model
T2-613-1-KK81 or T662-KK81 for under 2 Dollars. The inductors L1 and L3 are
standards value you can find smd or standard on ebay. About L4 you can put in
place a standard 4.7uH value increasing the series capacitor for
21 matches
