An RF modem used with a host device for transmitting information to, and receiving information from, other host devices. Prior to a transmission, the information is Manchester encoded and transmitted by On/Off Keying. A superregenerative receiver circuit (which may also operate as the transmitter) operating at the transmitted frequency detects the transmitted information. The information is recovered in conjunction with a timing function which times the buildup of RF energy within the receiver circuit so that a transmitted binary 1 can be distinguished from a binary 0. For use in a system with a plurality of hosts, multiple channels of operation are provided. In order to conserve power, the apparatus is operated in a power saving, sleep or scanning mode, as well as a full power active mode.
