The schematics show two internal crystal filters:

one on the receive path (2 poles) K3 RF Board
It's marked BW 14 kHz.  8215.0 KHz.
This has no relay to bypass it.

one on the transmit path (4 poles) KREF3 REF/2ND TX IF
It's marked 8215.0 kHz, BW=4 kHz
This has a relay to move to bypass it.

These seem to be in addition to the 5 user accessible
crystal filters.

So there seems to be large quantities of belts and suspenders.
