If so, is a diagram of that available? The manual shows the PTT connections for a panel mounted switch, maybe I am missing something obvious.
As Mike says, guidance is provided in Appendix D of the Rev. L GTR 200 Installation Manual to accomplish this, but if this is not clear, just email us and we will provide a marked up diagram.
We used to always show the PTT wiring being connected to the tip of the MIC jack in case someone wanted to use a hand MIC, but since so few do, we prefer to keep the PTT wiring totally separate from the MIC wiring as is presently shown in the manual.
