[Premium-Rx] Cubic WB Output Module

[GandalfG8 at aol.com]

Hi All
 
The recent discussion on Cubic modules reminded me that I have a module  from 
an unknown item of Cubic equipment and would appeciate any assistance in  
identifying where it came from, a schematic would be a big bonus.
 
It's similar in layout to the 3030 modules but where the 3030 modules have  
space for 5 coax inserts in the D type combi connector this one has a connector 
 that could take up to 8 coax inserts, and where the 3030 modules have a 25 
pin D  type for power and control signals etc this one has a 9 pin D type.
 
The module is labelled...WB Output
Assembly No....2881-1102A
Internally there's a usual range of components, including six medium power  
transistors with heatsinks screwed to the outer case, and two crystal  filters.
 
One filter is marked as having a centre frequency of 70.5MHz and a  bandwidth 
of 100KHz, the other as having a centre frequency of 3.0MHz and a  bandwidth 
of 1.0MHz.
 
Any ideas?
 
regards
