LF: 10MHz OCXOs

["James Moritz" <j.r.moritz@herts.ac.uk>]

Dear LF Group,

A while ago, I got a 10MHz OCXO reference - one of CARC's surplus goodies. 
It is a Piezo Systems model 2810007-1, and appears to be a clone of the 
HP10811 references. I have the pin-out for the HP unit, but I remember 
G3JKV mentioning that these units had a slightly different pin out from the 
HP original - does anybody know what the difference is?
Cheers, Jim Moritz
