The circuit of the P3 and the KX3 are massively different. If you had
bothered to read the P3 manual and study the block diagram/circuit
description you would not have made such a ridiculous statement.
The P3 does not create audio internally *at all* - to generate I/Q
would require essentially duplicating the P3's entire "IF" along
with a separate controller to maintain independent tracking frequency
control, an independent "wideband" I/Q audio output and digital to
analog converters.
