That might be where being able to flip a switch would come in handy. If I'm
reading the documentation right, the DEMI transverters prefer you don't use
full- or semi-break in with CW anyway, so you'd want it to just stay on
until you're done transmitting. That's a good point though, especially with
a portable setup.
