[GPS_Standard] Is this list still working

[Chris Howard w0ep]

It took me about 3 years to finally finish my GPSDO.
I think I got the last major bug out of it last fall.
My HP oscillator was from a scrapped frequency counter
which never employed the control voltage feature.  Come
to find out the control voltage wasn't doing anything!
I did a bit of soldering touch-up on the circuit board
and that has come to life. (I suspect it failed Q/A
on the control voltage issue and they just labeled it
for the other usage and went on.)

My GPSDO uses the VE3ZAZ board, the Trimble Resolution-T GPS
and HP 10811 oscillator.

Recently I picked up a FTS-4060 cesium standard
pretty cheaply and I've been running a characterization
of the GPSDO for about the last week.  I also
was able to replicate the Windows software statistics
calculation on my linux box with Bert's help.  So I feel like I'm
getting a pretty good grip on what the thing will do.

I will post a link to the ADEV plot of my data run when it is
complete.

I have also decided that cesium is overkill for me,
so I'll be selling the FTS-4060 when I am done with
this data gathering, in case someone on here is interested.
