This was done by measuring the cable harness length s. Also Tx Rx sells the different harness's at a nominal cost if you want to move the frequency higher or lower in the uhf band. He told me the duplexer was tuned on 444.
Com/products/duplexes%20-%20 triplexes/duple. Tx Rx uhf base station 350 watt duplexer model # 28-66-02A I bought this duplexer from another ham as part of a larger package. As you can see the frame has some cosmetic discoloration but this does not affect the units high performance. Bird-electronic.
I have had repeaters since 1988 and in my opinion I always felt Tx/Rx were the best around. 325 everything else he sold me was accurately represented so I have no reason to doubt that this would be any different.
