The potential ground loop via the RF cable connecting the OCXO output to
the Fury board can be broken by using an RF transformer.

This leaves (when the Fury and the interface board use separate
supplies) the EFC cable ground as the only connection between the Fury
and the interface board grounds.
If the Fury board and the interface board share power supplies then a
diff amp can be used to sense and correct for any volatage difference
between the Fury EFC ground and the OCXO EFC ground pin.

I just looked. The author of that piece was Alexander Calandra who has 
been cited in other parts of this thread. In that story he says that he 
was the arbiter. Calandra does not mention the student by name.

George

On board regulators with "remote" sensing can easily accurately regulate
the voltage between the OCXO connector pins and a standard differential
amplifier can be used to eliminate/reduce the effect of any small low
frequency voltage differences between the Fury and the OCXO EFC grounds.
Thus using on board regulators to drop the 24V to a lower voltage for
the OCXO should be OK.

Indeed! I suppose all sorts of stories surround 
our heroes, many true, many not. Well I remember 
the legend of Feynman before I met him in 1973 - 
a totally differnet person to what I was led to believe.

You beat me to it Poul-Henning, the legend is first documented in 
1958, but did not involve Bohr. I heard it in 1971 in the UK and gain 
in 1973 in the US - by then it is attributed to Bohr.

Some sources say that Rutherford was the arbiter. Why would

I later again heard the same legend in California in 1976, but about

Said,

In this particular case, I would solder a "single header pin", to each  
hole in the OCXO footprint, and then use a "single wire header  
connector" to attach to it.

Then, have all 4 wires connect to the interface board via a 4 pin, connector.

This way, the Fury gets soldered only once and can be disconnected anytime.

I will add that to the schematic.

Bruce Griffiths, has been providing me with some excellent feedback on  
the EFC interface design. I am making a few changes based on his  
recommendations.

The more I think about it, the more I am worried about ground  
isolation between the HP OCXO and the rest of the system.

I have a few ways to approach this. One is to simply provide 3  
different voltages to the system, each isolated from each other. In  
other words, don't use
voltage regulators to get from +/-24V down to 12.

The proper solution would be for a separate board which provides 3  
different DC outputs, all isolated from each other, including ground.

1. +24V for the oven. HP OCXO's only.
2. +12V For the oven. This could be supplied by the Fury which also  
compensates for temp.
3. +/-12V for the EFC interface.

The interface board must not add noise to the Fury. Looks like there's  
more work to be done.

Lovely! Not seen this before, but what a nice start to my day.

Thanks Christopher.

MY WATCH
AN INSTRUCTIVE TALE

MY beautiful new watch had run eighteen months without losing or gaining,
and without breaking any part of its machinery or stopping. I had come to
believe it infallible in its judgments about the time of day, and to
consider its constitution and its anatomy imperishable. But at last, one
night, I let it run down. I grieved about it as if it were a recognized
messenger and forerunner of calamity. But by and by I cheered up, set the
watch by guess, and commanded my bodings and superstitions to depart. Next
day I stepped into the chief jeweler's to set it by the exact time, and the
head of the establishment took it out of my hand and proceeded to set it for
me. Then he said, "She is four minutes slow -- regulator wants pushing up."
I tried to stop him -- tried to make him understand that the watch kept
perfect time. But no; all this human cabbage could see was that the watch
was four minutes slow, and the regulator must be pushed up a little; and so,
while I danced around him in anguish, and implored him to let the watch
alone, he calmly and cruelly did the shameful deed. My watch began to gain.
It gained faster and faster day by day. Within the week it sickened to a
raging fever, and its pulse went up to a hundred and fifty in the shade. At
the end of two months it had left all the timepieces of the town far in the
rear, and was a fraction over thirteen days ahead of the almanac. It was
away into November enjoying the snow, while the October leaves were still
turning. It hurried up house rent, bills payable, and such things, in such a
ruinous way that I could not abide it. I took it to the watchmaker to be
regulated. He asked me if I had ever had it repaired. I said no, it had
never needed any repairing. He looked a look of vicious happiness and
eagerly pried the watch open, and then put a small dice box into his eye and
peered into its machinery. He said it wanted cleaning and oiling, besides
regulating -- come in a week. After being cleaned and oiled, and regulated,
my watch slowed down to that degree that it ticked like a tolling bell. I
began to be left by trains, I failed all appointments, I got to missing my
dinner; my watch strung out three days' grace to four and let me go to
protest; I gradually drifted back into yesterday, then day before, then into
last week, and by and by the comprehension came upon me that all solitary
and alone I was lingering along in week before last, and the world was out
of sight. I seemed to detect in myself a sort of sneaking fellow-feeling for
the mummy in the museum, and desire to swap news with him. I went to a watch
maker again. He took the watch all to pieces while I waited, and then said
the barrel was "swelled." He said he could reduce it in three days. After
this the watch averaged well, but nothing more. For half a day it would go
like the very mischief, and keep up such a barking and wheezing and whooping
and sneezing and snorting, that I could not hear myself think for the
disturbance; and as long as it held out there was not a watch in the land
that stood any chance against it. But the rest of the day it would keep on
slowing down and fooling along until all the clocks it had left behind
caught up again. So at last, at the end of twenty-four hours, it would trot
up to the judges' stand all right and just in time. It would show a fair and
square average, and no man could say it had done more or less than its duty.
But a correct average is only a mild virtue in a watch, and I took this
instrument to another watchmaker. He said the kingbolt was broken. I said I
was glad it was nothing more serious. To tell the plain truth, I had no idea
what the kingbolt was, but I did not choose to appear ignorant to a
stranger. He repaired the kingbolt, but what the watch gained in one way it
lost in another. It would run awhile and then stop awhile, and then run
awhile again, and so on, using its own discretion about the intervals. And
every time it went off it kicked back like a musket. I padded my breast for
a few days, but finally took the watch to another watchmaker. He picked it
all to pieces, and turned the ruin over and over under his glass; and then
he said there appeared to be something the matter with the hair-trigger. He
fixed it, and gave it a fresh start. It did well now, except that always at
ten minutes to ten the hands would shut together like a pair of scissors,
an
