From the current crop of ebay OCXO's available, what have you actually used
that you would recommend for the following? Sine output, either 5V or 12V,
better than 0.2ppm stability after warmup. I plan on putting things in a

You can run at 400 KHz by dividing by 5/5 and 4/9.
True. Either will work.
You said 0.2ppm stability. What do you need for accuracy and/or how
are you going to calibrate your setup?
I will initially calibrate the OXCO against my HP GPSDO. Idealy, it will
only need checking against the GPSDO
If 0.2 ppm over a narrow range is the objective, that sounds like a TCXO
application.
Please point me to such a TCXO at 14.4 MHz that is affordable.

As asked by another, please post a PDF of the schematic. I don't have
any software installed
Any chance that someone could purchase a small quantity from Arrow
Germany so Stanley could include them with the boards we ordered?
Extra payment for the chips, of course.

Ok guys, it has been sitting on my floor far too long and I don't know
when I'll get around to working on it. When I last messed with it, I
went through quite a few of the performance tests and IIRC, most

Without naming names, I want to suggest that if anyone on this list is
going to ship IC chips in the future (DIP in particular), that they
either use the hard plastic tube the chips come in, or put the chips
inside a box. Antistatic foam inside a padded envelope results in very
flat pancakes. Just
This has to be the coolest POV clock ever:

This is not strictly Time Nuts, but it is about a crystal oscillator that
needs some temperature compensation, or something. Please ignore this
posting if you like. In fact, so as not to clutter up the list, it would be
best to email me directly about this.
I have an old AM transmitter that has
Can you show some pictures of the oscillator?
The wiring is point-to-point, so I don't think a picture is going to tell
you much.
Is there a tunable inductor in the oscillator circuit?
As I mentioned, nothing tunable there.
Who makes the unit?
It is an LPB RC-6A carrier current AM
Charles, you obviously are familiar with this transmitter. You don't happen
to know where I can get a schematic, do you?

Otherwise you might just as well lock it up instead.
Hmm, a 1970 vintage tube transmitter with a GPSDO frequency lock :-)
Thanks to everyone for the suggestions. I will spend more time with this
rig and see what works.

More goodies from QST. Attached is an article about the very first ARRL
Frequency Measuring Test.
At just over 2 MB, that attachment was too big for the list. Find it here
for a short while:

And while I'm at it, here
That PDF shows 2.4 MB on this end. I guess the MIME encoding really bloats
it.

Tom,
Thanks, but I already reposted with links to that PDF and a followup. Feel
free to post a permanent copy of both. I will delete
attachment was 3.4 MB (too large for the list) so I put a copy

Burt,
Thanks for the information. I thought that the tolerance was supposed to
100 Hz, as You said. As far as I know, this is the original crystal that
came with the rig when NMSU bought it. I will spend more time working with
the rig this weekend.
I am looking for a solid state LPB transmitter,
