[Boatanchors] couple or three questions

[Peter Markavage]

If you're running coax out of the tuner using coax 1 or coax 2, the
shorting bar is a don't care. The shorting bar is necessary if you're
connecting the balanced feed directly to the back of the tuner. Doy Key
Relay works great for receiver/transmitter antenna switching. The simple
way to do break in is to use an electronic TR switch. Johnson and B&W
made them and it's simple enough to build your own.

Your last question: "is it enough to shut the antenna off or maybe ground
it while transmitting?"
Never good to shut the antenna off (??) or ground it when transmitting.
Makes the RF go to all the wrong places.
