[time-nuts] Cheap Rubidiums

[Bob Camp]

Hi

I agree that there indeed lab grade rubidium's out there that run well below
1x10^13. There are also a bunch of orbital rubidium's that do the same sort
of thing.

The idea is to see (short of buying several swimming pools) just how good a
cheap rubidium can be made to work with "basement level" engineering. 

Each "system" should have:

1) A Thunderbolt w / antenna for very long term ($100)
2) A cheap rubidium for medium term ($100)
3) A DOCXO for the short term ($50)
4) Some FPGA / micro controller stuff to stitch it together ($150)
5) Power supplies ($30)
6) Enclosures and misc ($50)

Hopefully the total cost per system will be below $500 at eplace prices.
Unless there's a magic place out there that I'm not aware of, I'm not going
to get a working 5065 or a working hydrogen maser at anywhere near that kind
of price. 

Bob

Bob,

While not considered cheap you may want to consider an HP 5065A.

See my post "Short term stabilities of some HP 5065A" in the Sept. 2008
Time-Nuts.

These were plotted in an uncontrolled environment.

As you can see quite a few were in the  <7X10-14th range at 1000 seconds.
