Yes, the TX/TEST feature in the K3 works in all modes.  All it does is
prevent RF being transmitted.  The rest of the TX functions as normal.  You
can use it in SSB, for example, to set your MIC and CMP settings and listen
in the MONITOR and adjust its level, all without going to a dummy load or
transmitting RF to an antenna.  A very nice K2 feature, further enhanced in
the K3, and it is very handy.

Different issue entirely.  There are a number of operational scenarios
needing to gate CW transmission (on AND OFF) with PTT/footswitch.

Thanks Ed on both counts. I am glad test works, and indeed I was
confused about the PTT/QSK mode issue being discussed.
