Anybody else notice the 10 pin audio connector, U-79, mates with a U-77?
Lots of non US stuff has used our connectors, I dont know that we did not
get it from somebody else.  What is the earliest use of this connector?
AN/GRC-3-8?  Before 1951?  

Seems like he got the transponder from "APX" on the front panel.  

The only connecter seems to be the U-79,  and it might not be used for a
photo flash, however these type audio connectors have been used for power
applications, such as the 5 pin audio connector used on the Trimble GPS
AN/PSN-10.  

My guess would be an audio meter, or some type of modulation meter.  The
lighting bolt symbols would represent different test modes or test setups?
Does not have anykind of RF connector.  

If it is not German it might be Swiss.  Just my opionion, not very strong
on any of them.
