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. 73, ...
