Abstract: Acknowledgement apparatus for use in a radio postal system of the type employing an orbiting relay satellite for transmission, including receiver reply circuits operating at a narrower bandwidth and with a lower signal-to-noise ratio than are associated with corresponding transmitter message circuits so as to enable use of reply circuits of substantially reduced power.
