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; and
a receiver adapted to switch between receiving one of an upper sideband and a lower sideband of an external SSB signal.
