Brad, I'm not familiar with that model number. Is it a can-type; or perhaps a smaller one to go inside a portable-type repeater?
I have a manual for the Phelps-Dodge can-type (pass/reject) duplexer; but it's discussion is pretty simplistic. There are several in this group that are better experts on duplexers than I am; but if you don't hear back, and if it is the can-type (pass/reject) duplexer, let me know and I'll post it in the Files area. <<< vern ([EMAIL PROTECTED]) >>> --- In [email protected], "n3nrn" <[EMAIL PROTECTED]> wrote: > > ...
