So if I utilize these same compression and hpf adjustments and
equalization my 100W will sound like 1KW?? maybe on paper..

As the saying goes, "Five watts is five watts".
The saying is an oversimplification. The KX3 includes two important
tools to increase talk power on SSB -- TX equalization, which can be
set to emphasize speech intelligibility and minimize power wasted
below 400 Hz, and amplitude compression and peak limiting, which
brings quieter speech sounds closer to the level of louder ones. When
set for about 10 dB of compression on voice peaks, it makes 5 w the
equivalent of 50W, and the TXEQ settings add 3 dB, making 5W the
equivalent of 100W.
These tools, which are called "audio signal processing," have been
used in broadcasting since at least the '50s. They are also built into
the K3, K3S, and KX2.
