ABSTRACT:
Two pilot signals transmitted at the beginning of transmission from a transmitting station are demodulated in the receiving station and one of the demodulated pilot signals is phase compared with a reference signal generated by the transceiver. A phase comparator generates a control signal having a voltage corresponding to the difference between the compared signals. The control signal is input to a local oscillator of the transceiver which generates a signal to automatically tune the transceiver to the incoming signal frequency.
