Bill,
QSK while ragchewing or contesting is pretty much of a waste. Semi-qsk
is fine for those.
But I used to use QSK all the time when I was traffic handling on cw.
You didn't need to send a whole string of characters for a fill when
the other end didn't copy. The other end could just break in
immediately after the missed character(s).
Been a ham for 54 years and did a lot of cw traffic back in the day. It
kind of died off about 20 years ago and I don't need it any more.
Semi-qsk with the modern radios seems to work fine for me.

We were thinking the same thing... shorting the opposite rail to
ground of the mode you are in. My circuit was a bit different using
a modified schmitt to the base of the transistors but it provides the
same result (that way one is not on while one is off at any time).
And i know i can design a diode switch that takes less current than
the relay coil so good there.
Im a CW op too for close to 50 years ... in major contests too but I
never got the QSK thing. Seemed like a telephone call in the middle
of another call to me but thats just me. It would probably work for
my wife who thinks much differently than me.
