Many of you have doubtless thought of this,
but if one is looking for a way to "key" the TX
Prog Rocks so you don't have to leave them
running while you receive, tap-off the coil
voltage if you have a PTT relay and run it to
your progrocks.   They'll run only when you key.
If you don't have a PTT relay, there is still some
means of turning-on your PA and, with a little
tinkering, that switched voltage can be made
to key the ProgRocks.
