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.
