After cleaning this duplexer up and making a new cable harness for it, I wanted to tune it for repeater use on the 2 meter band. Since I had taken apart and re-assembled the duplexer, I started with a rough tuning of each cavity individually, then proceeded to a fine tuning and alignment with the cavities connected together with the new cable harness.
