Mike,
My explanation stands, but "not really usable" isn't a fair
assessment. I frequently use the KX3 in the BC band. I can clearly
copy all the same stations with the KX3 that I can hear using other AM-
capable radios at my QTH.
The KX3's receive sensitivity does fall off by design below a
A discussion of KX3 MF lack of sensitivity recently took place
on the KX3 list. The KX3 should not be considered really
usable below about 1500 kHz, as Wayne explsined:

Wayne,
A side benefit (bonus) of my new KX3 is use at 472-478 KHz (recently
authorized at WARC for ham radio use after 1Jan2013-pending FCC
action) and 495-510 KHz using my WD2XSH/45 experimental
license. Your comments on use of KXAT3 below 1500 KHz was
particularly noted and hope this means
Stephen,
The broadcast-band preselector components on the ATU option do in fact
optimize receive performance in the 0.5-1.5 MHz range. However, the
criteria being optimized by the preselector is rejection of harmonic
images (typical of a zero-I.F. receiver), not necessarily sensitivity.
