[Milsurplus] Module ID

[Glenn Little WB4UIV]

I have some modules that are from an estate.
I think that these may be for a military portable radio.
These are 2.25" long and 0.75" high.
These have gold pin connectors.
These connectors have a slit that allows these to mate with the same 
connector pin rotated 90 degrees.
These connectors mount to the board with two solder tabs and are 
3/16" long and 3/32" high.
The pin spacing is about 3/32" with the spacing maintained with not 
installed pins.
The board material is tan fiberglass about 1/32" thick.

Any ideas as to what these modules may be from?

Thanks
