Did the tbolt happen to use one? I've got a dead TAPR tbolt from a 
lightning strike that I can rob from if needed.

The first HP10544 I held in my hand  was 10.23 MHz part of the GPS project.

Hi Tom,

   I ran across one the other day, actually, looking for something else.

   Surplus Sales of Nebraska has an HC-6 crystal as p/n (CRY) 005.115000

   

Probably not exactly what You were looking for, but a start!

Mark

IIRC someone has offered a 10.23 MHz variant of the 10811 some years ago 
on the list.

I have seen 10.23 parts somewhere but can't remember the application.

If you can't track one down there's still a couple of reasonably priced
options for custom crystals, you can have them ground by a czech company,

[time-nuts] 5.115 MHz / 10.23 MHz wanted

[Tom Van Baak via time-nuts]

For a DIY project I'd like a 5.115 MHz OCXO. That weird-looking number 
is half the basic 10.23 MHz GPS chip rate.


I realize it's trivial to create 5.115 MHz with a DDS chip, a function 
generator, synthesizer, or even an aggressive phase microstepper. But in 
this case, if possible, I'd prefer a simple single part; a plain old XO 
or OCXO solution. Do any of you know where to get a 5.115 MHz crystal or 
oscillator?


I'm pretty sure that I've seen one-off surplus 10.23 MHz or 5.115 MHz 
OCXO on eBay but I never thought to bid on them because the frequency 
was strange. If you saw one, and "bought before you thought", let me know.


Thanks,
