Can anyone suggest a "starter" atomic clock project? By beginner's
something that is fairly easy to put together and isn't cost prohibited
(maybe a few hundred but not thousand).
Thanks!

Alex,
Perhaps you could clarify what

Do you mean "build the physics package", or are you just talking about
Hi
What are you really trying to do here?
If it’s a “from scratch” atomic standard, then you just aren’t going to get
there. Sorry about that ...
If it’s a wall clock sync’d to an external radio service then indeed you
might get there.
In-between those two lie tings like buying eBay telecom

Rick,
Thanks for this information. Actually the technology of C18 is not specified in
the manual.
Why should it necessarily be « foil » type and metallized?
Is « foil » type same as « film » type?
Of course the « mass » needs to be there (=> 3D
Hi Jan,
this is precisely the instrument that is lacking at a hobbyist price.
It would be excellent to have the possibility of measuring phase noise.
Can you anticipate the features of the Sampling DMTD?
Can it be used with Timelab?
We are waiting for your new ones.
I understand several of the modern MEMS OCXO's use microcontroller PID
control for the temperature, avoiding the need for any large capacitors for
compensation.
The microcontroller does a lot more than the heating job, judging by the
PhD thesis I see coming out of China. They seem to feed-forward
First off, thanks to everyone who replied.

Ok.
Hi
You are not going to get useful phase noise data out of a normal DMTD ….
The DMTD is targeted at ADEV and similar long term / high accuracy
measurements. If a DMTD “makes it” to a 10 Hz beat note that is about
as far as most people take it.
