Yes, but we modified/replaced the loops in the cavities to get better performance. No changes were made to the harness as I recall. I don't recall the Pass/Rejectfigures at the moment (but they were comparable to other 4 cavity 2 mtr. duplexersor slightly better, but the duplexer has been operating on the K4SLB 2 mtr. rptr. in Kissimmee Fl for the last year and a half. You'll need access to a service monitor with a tracking generator at least to make the mod. It's a reasonably simple mod. and all that was required was some #14 Ga. bare copper wire, a soldering iron and your time and access to the SM. Other may have different ideas or suggestions.
