[Milsurplus] Help with unknown Navy item

[Joseph Pinner]

I have a Navy Item which I need help identifying as well as locating  
documentation. It appears to be a receive only antenna switching  
panel. It can be controlled via a computer link or manually from the  
front panel. It is filled with those expensive small sealed coaxial  
relays. I also has a flexible band pass filtering scheme for VHF/UHF  
frequencies. Functions are read out by way of LED panels.

A picture can be found that the following link: http://

I believe that it was manufactured sometime in the 1980s. Could be  
later but I doubt it.

Its functions are as follows:

   HF Receiver - selection of four different antennas

   HF Receiver - selectable HF attenuator

   VHF Receiver - selection of two different antennas

   UHF Receiver - selection of four different antennas

   VHF / UHF - adjustable bandpass filtering

Any help out there ?????
