Thanks to the engineering ingenuity of Jerry Ritchie (WA5OKO) and the resourcefulness of Jim Rogers (N5VGQ) to find the necessary parts, they have managed to co-locate both repeaters on the same East Mountain tower utilizing the one antenna complex. This gives both repeaters great range. There is still some tweaking that will need to occur over time.
Jerry took the time to explain how this was accomplished by publishing a document that goes into the details of multiplexing. Below is a link to his document. You will need Adobe Reader or Adobe Reader web browser plugin to view it.
Again… many thanks to Jerry and Jim!
