The K3 sensitivity falls off severely below 160 meters. But if you have the IF
option (KXV3)
which provides a receive antenna port it does not have the filtering, and there
is plenty
of sensitivity over the whole band (0.5-1.7 MHz). The KXV3 is very useful for
160 meter
use as it allows use of a Beverage.
You should be able to make your signal level/readability tests without a
seoarate AM
filter. I just checked on my K3 and sensitivity falls off very fast below 1.6
MHz.
