K3 ain't your daddy's analog radio...
Incoming signals are handled as analog signals until they are
converted to a 15 kHz IF. At that point the analog is converted to
digital. All the rest is done in firmware as part of the number soup.
Calling firmware functions IF or AF is really a misnomer.

The best guess is that Kenwood did not want to invest in 1) the high
performance front end (bandpass) filters for the non-amateur bands,
They're probably trying to save money by eliminating a bunch of tight
band-pass filters for the ham bands. They're betting that no one needs
high dynamic range on any bands other than 1.8/3.5/7/14/21 MHz, nor on
any modes other than SSB/FSK/CW.
I beg to differ :)
