Isolate any jacks/controls from metal chassis? #ubitx

Rob French (KC4UPR)

Are there any controls or jacks that I should isolate from my metal chassis?  Specifically, I'm thinking of the PTT and C/W key inputs, since those are wired to the Raduino.  Since they are part of the digital circuitry to some extent, should they be isolated from the chassis ground assuming I've got, e.g. the antenna RF out ground there?
