Invar is a special material. It is special that is has very low tempreture expansion characteristics. When used for the tuning rod in a duplexer it will compensate the expansion in the copper center conductor so that the frequency of the cavity does not drift. I calculated a 6m cavity that uses st

Jeff, I suspect you may be headed for disappointment. CTCSS (PL) and CDCSS (DPL) are handled differently within the radio. While the former is audio, albeit sub-audible, the latter requires a DC connection to the modulator in order to create the DCS signal at a 134.4 Hz rate. In other words the

I could live with 3dB of loss which is about what I would expect per leg. I've ran the UHF notch duplexers "back wards" and they have ran ok, but the insertion loss does go up like 1-2dB. If you want to get picky you would have to modify each set so that the coupling loops and coaxes are the same,
