Title of the Invention, SSB TRANSCEIVER Abstract of the Disclosure, Two pilot signals each transmitted with a predetermined but different frequency are demodulated in the receiving station and sent to a control circuit controlling a saw-tooth wave form voltage generator which is continually varying the frequency of an automatic tuner. The control circuit acts to stop the voltage generator when the demodulated pilot signals have a frequency equal to the predetermined frequency. The received signal can thus be automatically tuned to the transmitted signal.
