The only addition to your list is a receive preamp if you're running full

duplex.

Norm, I completely agree. I hang a ARR 432 pre-amp with it's own small 12v pack between the diplexor and the 432 side of the Arrow. I have an RF switched version just in case I do something stupid with the FT-530. I use a headset so there is no audio feedback/echo.

Makes all the difference on low passes (<5) and less than optimal locations.
