Attached is an article from WD8OYG that is very good.

How do you combine a 2 meter voice and 2 meter digipeater on the same antenna??
Here, we have a repeater on 147.06 and digi on 144.39. We're using an old Sinclair Q2B05D duplexer to "combine" the two.
The voice repeater has it's own duplexer. The antenna port of that duplexer feeds the high frequency port of the Sinclair duplexer. The Sinclair pass response is wide enough to pass both .66 and .06 with no problem. The digi radio feeds the low frequency port of the Sinclair.
In addition, we needed to add a pass cavity to the digi radio, and a pass
cavity to the repeater receiver. It all works great, with no desense to either
receiver from either transmitter.
Several months ago (May or June?) on this list, someone posted *their* method
and diagram for doing the same thing. Perhaps that person could re-post the
info. Or, search the list archives.
