Byron,

Not possible.
The K1-4 has only 2 low pass filters, one has a cutoff frequency above
the 30 meter band and works well for both 40 and 30 meters. The other
has a cutoff above the 15 meter band and works well for 20, 17, and/or
15 meters.

You could use the lower band for 160 meters (with a lot of re-design),
but it would become a 3 band board - the LPF filter would have to have a
cutoff frequency below 80 meters to suppress the 2nd harmonic. so 2
bands on that LPF would not be possible.

A better choice to add 160 meters is to use a 2 band board.  If you want
the details of the components to be added for 160 meters, ask and I can
send them to you - the component values have been posted before, and you
may be able to find them in the archives (3 or 4 years ago).
