There is also a circuit originated by K1KP, and publicized by K6XX, 
which does not need a high voltage rail. It works directly from the 
relay's existing supply rail.

This whole thing is a race against time to avoid hot-switching, so it's 
vital not to waste valuable milliseconds using a relay-driven PTT output 
from the transceiver. It's got to be the fast solid-state output.

The version of the K1KP/K6XX on my website includes a low-voltage 
interface that will work with even the wimpiest solid-state output.
