I have the techbook, it's scribble drawing from a tech. It doesn't show how to connect the wires with the connectors used. Actually the SRD-4000 is still usable and can receive digital stations. I have been sent a list of what is available...very cool.
are you still in need of the manuals, I have SRD-4000 installation & operation manual, owner's manual for antenna positioner SRD-4000 and a 4 page brochure explaining the operation of the receiver and how to do a master clear if you don't know the code that has been entered.
