You must also bear in mind that this a world-wide list. personally I would
not be interested in sales of test equipment within the US, and I would not
look here for equipment I might like to own. (Others in the Europe might)
However, I would not object to a note that some gear is avilable and a
I plan on replacing the Xtal Osc. of my HP 5062C with a HP 10811 since I
have a few ones with AV less than 1E-12 from 1 to 100 sec. I would like to
use the +18 Volt in the unit for heater. Has any one experience with running
the 10811 below 20 Volt, any thing I should look out for?
Thanks
I think you should probably be fine at 18V. The oven will run down
to at least 15V and maybe 12V.

Thank you Rick, you obviously must know.

Hi:
I've been winding a number of loops for WWVB and have one that looks
good on test equipment.
You should do a test where you warm the rod+windings in your hand,
I found the center frequency would drift significantly with even
minor
Hi
Also consider that there is a maximum practical Q for a rod antenna. Past a
certain point the Q goes up because the flux is better contained. For an
antenna to work, the flux can't be fully contained. Simply put, a toroid or pot
core will make a very high Q inductor. Both make really lousy

But then again, avoid the issue and go for a black hole antenna amplifier.
I've been gathering information on Black Hole Antennas for a while on
my web site:

As I understand it, 60 KHz information is so slow that phase
information is critical. Why would anybody use a resonant
antenna in that situation? The phase shift from day to night
is more than enough to work around.
I used a non-resonant antenna proposed by John Ackermann
against Z3801 outputs
Bill what are you asking on the spectracom and model number please?

Tried resonating it, got unstable results.

Gents,
Time nut junkie that I am, I’d like to someday acquire a cesium standard.
Several questions: price for a reasonably working unit. Any specific model
that one should look for? What about the AS IS HP units that show up on epay?
And if you get one how can you know or test it that it’s

Brian,
As only one of the listed frequencies are usable in the US, you would do better
buying an ATOMIC clock at your local Walmart for around $20. That way you
also
get a nice display and it includes the same basic receiver inside.

Perrier,
You may have missed some bits. The plans are in the archives,
or ask John, your list manager. The coax is 1/4 in diameter
but doesn't have an RG designation on the cable. I used it
indoors near a window because 60 KHz isn't greatly affected
by wooden construction.
There is no resonating
Perrier,
I have a FTS (Datum) 4040A CS standard with large foamed shipping case
for $500.
Yes, it works. Does not have a computer interface, but does have a C
field adjustment
just behind the rack ears on the left side.
Paid $1200 for it in a local sale several years ago. Used it, but the
