1. A time division duplex (TDD) single sideband (SSB) transceiver, comprising:

  • a transmitter adapted to input an analog audio signal, sample the analog audio signal, and to output an SSB frequency shift keyed (FSK) signal corresponding to the analog audio signal, the SSB FSK signal including analog information;

    a receiver adapted to switch between receiving one of an upper sideband and a lower sideband of an external SSB signal and, link management device adapted to detect interference when said receiver is receiving one of the upper sideband and the lower sideband of the external SSB signal to provide a control signal to the receiver in response thereto, and to detect the interference when said transmitter is transmitting one of the upper sideband and the lower sideband of the analog audio signal to provide the control signal to the receiver in response thereto.
