Ham Radio UHF Repeater Duplexer testing and repair

Noisy ham radio UHF BPBR WACOM duplexer, testing, diagnosing, rust removal, disassembling and repairing and reassembly. Testing performed with HP spectrum analyzer with tracking generator. Video made afterwards from photos taken during tear down, test and repairs. This information is applicable to other bands and types of duplexers. I did not plan to make a video of the process, but think that this would be of educational value to somebody getting up the gumption to tear into a troubled duplexer. 73 N3SDO
