No, the K3 CANNOT switch a negative voltage for keyout! It is a solid-state circuit which
is quite robust (+200v at 5A), but only for positive DC voltages.

The K3 DSP works just fine. In fact all the filtering, modulation,
demodulation as well as many other radio functions are implemented in
DSP firmware, not just the NR that has been recently discussed.
These folks have specifically been talking about the K3 Noise Reduction
algorithms.
Suggest you use one of those amp keyer interfaces for this amp. As an
option, also look at the universal keying adapter from HamGadgets.com.

Larry,
Sorry, but the KPA100 and KAT100 both depend on internal K2 signals for
control - T-R switching, band selection, etc.
That makes the KPA100 an amplifier dedicated to the K2, and the KAT100
autotuner is also dedicated to the K2.

Try setting mic gain to 0, then increasing it slowly to get to the 4 or

An interesting point I noticed modeling a 43 foot vertical was that, while
on 10 meters the main lobe is up around 50 degrees, the gain at low angles
is similar to a 1/4 wave ground plane antenna cut for 10 meters. That's
because the longer antenna has significant gain over a 1/4 wave antenna so
