K3 - Multiple Concurrent Filters?

[Fred (FL)]

With the expected wide range of ROOFING, and GC
filters to be offered for the K3 - how many filter
spots are available, to physically install filters
into the K3?  Can we have a GC, ROOFING CW, ROOFING
FM, and ROOFING SSB - or GC/SSB/CW/FM filters
all concurrently installed somewhere inside the K3,
at the same time?   Or will it be an either/or?

If we buy 3 of them, can we use all 3 at the same
time?  (GC, CW, SSB)

In a IC-706MKIIG - one gets the supplied IF
Roofing Filter, and there are pcb spots for a CW
and a SSB filter - all at the same time.  Then,
Icom's firmware knows about all 3 of them.

Order in, waiting on the tarmack

Fred,

Each receiver has 5 crystal IF filter slots.  When
shipped, a 2.7 kHz filter is included, leaving 4 more
slots available.  This includes the main receiver and the
optional subreceiver as they are of the same design.

These IF crystal filters are not mode dependent...meaning
you can choose any filter for any mode.  The filters
installed on the main RX also share transmit duty as well.
 Filters on the optional subreceiver are ONLY for receive.

The KBPF3 bandpass filter for improved general coverage
receive does NOT take up one of the crystal IF slots and
is only inline when you tune outside the ham bands.  Once
you are back inside the ham bands it is switched out and
the ham specific BANDPASS filters are switched back in.
 Remember I'm talking bandpass filters and NOT the crystal
IF roofing filters here.  The roofing filters can be
chosen in any mode and on any frequency and work in
combination with the DSP IF and DSP AF filtering.

Hope this answers your questions and thanks for asking.
