[Milsurplus] Cubic Corp DM-20 Manual wanted

[Jack Antonio]

A bit off topic, although the Navy bought some in the 60s, and I used 
them on a survey crew

when working at NAD Hawthorne, NV. So they can be considered 
milsurplus.  They are

a microwave distance measuring system.

Looking for a manual.I don't have one, but just trying to remember the 
details

of how it worked.

Operates at 10GHz, in the amateur allocation, and one of the other 
members of the

survey crew I was on had a ham license, so we had a legit ham QSO.
