ABSTRACT:
An improved proximal cable-less communications system using at least two receivers is described. The system is significantly improved by eliminating the sidetone which can occur in full duplex systems. Components are placed in the receivers, between the mixer components and the components which detect the information encoded in the signal at the intermediate frequency, which function to cancel out the detrimental affect of those signals containing information derived from the modulation of the local oscillator of the receiver device.
