I did a little research last night and all I could come up with was a REMIX NB. It called for LDI-4984. The LBI is nothing like the item shown. A little more research called for LBI-4778 (which I couldn't find) and called it a 138-174 MHz Oscillator Multiplex board.
Sorry I could not be of any help. Hey Steve, how is Ashland?
