Levent, The pictures do lend credence to the "special part" theory. Please advise what the two receive and two transmit frequencies are. Do you have any idea what company or agency owned this device? It's a long shot, but it is always (well, sometimes) possible to track down the previous owner, locate the radio shop that maintained it, and possibly identify the documents you need- if they won't just hand them over. Knowing the frequencies used is a giant first step in that process.

Sorry I forget the mention I put the picture under GE Lookup Repeater folder. There ais one more Number I find it is on the back of the unit and it is PL19D424600G4 this is on the back of the box. 73 Levent - WW2L --- In Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> , "Eric Lemmon" <wb6...@...> wrote: > > Levent, > > The component number 19C320943G1 is a "SPCL COMP BD". > > I think it's time to take some pictures of this device, since it seems to be > an oddball unit that was not a regular production item.
