Mark, If I remember correctly. And it has been a while.
The Motorola community repeater both the MSY (Motrac-Motran vintage) and the Micor The PL came in the receiver and the master decoder would match it to an active PL or DPL reed or codeplug. Then the station would repeat and the same Pl from the receiver would be Passed via the reed of codeplug to the master decoder and then on to the exciter via way of a filter board that was installed in the exciter where a "normal" radip would have the PL or DPL encode board. It sounds like you may be missing that filter board. Is it there ? if not I suspect that you could use a regular duplex DPL encoder board to buffer and pass the signal. As far as the master decoder the flow through the MSY and the Micors are very similar. I do not believe that the MSYs ever had DPL. So it makes sense that the path and the pass band for the MSY would be different from the Micor cutoff at DC vas 67 or so Hertz. The MSY board could be made to work I would guess if you had the schematic I had a book on a MSY CR somewhere I will look and see if I can find it. HOWEVER I just bought a warehouse (I buy and sell communications equipment) That has a box of Micor cards in it. I thought of you. Send me the part number that you need and I will get one to you.
