Thanks to Mike to his observations on the driver - using stock NTP would be

I followed fellow time-nut Gotz method of replacing the z3805 with the
z3811 in Ulrich's Z3811 program and it works very well. All of the stats
seem to be working on the Lucent 24361. I kind of wonder about doing the
same for the crystal oscillator as its a Z3812 if there is any usefulness

One way to somewhat decouple the channels cross-talk could be do delay
one of them with a coax cable.
This will make the cross-talk of the early channel die out pretty much
before the next edge come.
With two asynchronous sources you will sweep over the repeating pattern
of cross-talk and
Hello Friends,
I found this new inexpensive GPSDO on ebay listed from a seller from China:

It looks interesting and tempting BUT the seller doesn't give any spec's
Hi Dave,

We had that issue with the 5335A at work, and replacing the relay did
the trick.
5335A is still the counter which is easiest to use, even if it doesn't
have stellar performance, but usually that is not needed.
Where did you find the Service Note?
Cheers,
Magnus

Charles Steinmetz posted a link to Wenzel Squaring circuits in Li Ang's thread,
and I'm particularly interested in the line receiver method. On the wenzel.com
page the line receiver was an SN55182. In Bert Zauhar's GPS Standard, he used
an LTC-1485 for the OCXO input. Is there something in

Dave, these have been discussed in the past at some length on this
list. I would point out that they use a re-cycled Morion OCXO. I have

I did some test according to your suggestions. DUT is a symmetricom x72

My first vote would be for merging Z38xx into Lady Heather. This from the lazy
guy who is *not*offering to do all the work. I would be perfectly willing to
beta test the results on this option or any of the others.
My second vote would be for open sourcing the Z38xx program stand alone so

There 2 issues from the test:
1) As we can see from the data, the number is around 1.98x not 2.00x. So
there is about 2ns delay between tdc_start and tdc_stop1 for this simple

I have two queries. Both hopefully quick to answer
1) From what I gather, the HP GPS timing receivers can be
observed/controlled with HP SmartClock. But where I download it from? I
drew a blank with Google, as well as the Microsemi site

No better than any other system given similar environments.
Would it work any better than the Raspberry Pi cards I am
Hi
Quick summary if you don’t want to go back a month or two in the archives:
1) They appear to be a club project done by a ham club in China.
2) There are multiple versions in the pictures, some with more jumpers, some
with fewer jumpers.
3) The design appears to be pretty new. Dates are all
