In my limited understanding of the K3 signal path, there is always a
DSP operation on the signal for filtering. While noise blanking, noise
reduction, and audio effects can all be switched off, I don't know if it
is possible to remove ALL digital signal processing from the signal
path; i.e., operate only with the crystal filters.
The product detector (or FM discriminator) is implemented in the DSP
firmware, so, if you could bypass the DSP, you would have a signal at
the final IF frequency (15kHz?), not a baseband one.
