#48 UHF homebrew duplexer cavity build and testing.*Heavily Caffeinated*
In this video I spent a week building and testing one cavity for our homebrew UHF duplexer project. I show where the
design originated from and how to build the second cavity. In the next video we build the other two cavities, check out
VSWR and do a full tune up of the duplexer. By this time I plan on having the UHF repeater running.
