Perhaps a location for an alternate receiver used in another model/version that shared the same PCB albeit populated with different OCXOs etc?.
Interesting that 2 ocxos appear to be in use.

 Isn't the GPS receiver the Furuno GT-8031F timing module in the upper 
right corner?

It seems can use a RS-232 cable and simple SCPI or serial command to control it, just like HP 58540 or other GPSDO  board that I had, and there is a blank place on PCB that seems can install a big OCXO or SUB-Board? I don't sure, so I would like to find more detail of this board, it has a reasonable price so I can get one. Any information will be appreciated.
