I'm building a duplexer similar to the Decibel DB4032 for 6m, so far one cavity has been built and measurements look promising.
Concerning the cable harness I know that some diagrams have been published with adjusted cable and stub lengths for ham use, but I would prefer to know how these are calculated as I need to have the duplexer on Swiss 6m repeater frequencies (51-52 MHz) and do not know how much difference this makes. Can anybody help? 73 de Martin HB9TZW
