A KBPF3 can be mounted on either or both the main receiver and KRX3.  It
functions the same in each receiver and adds the band pass filters to cover
the frequencies outside the Ham bands.  The benefit is allowing reception
outside the Ham bands.  There is no performance impact in the Ham bands with
the KBPF3 installed.  It is out of the circuit and not used inside the Ham
bands.
