[time-nuts] HP 10811-60105 OCXO

[Robert Crawford]

Jason,

I'm fairly certain the 10544 is a 10 MHz oscillator.  The 10811 is an 
improved version with way better performance and it can usually plug 
into the same connector.

There is a great article on the 10811 in the March 1981 issue of HP Journal:
