A battery-powered portable radio conserves battery power while the radio monitors messages transmitted over a radio channel, e.g., a radio control channel, Message processing circuitry processes a detected message and stores that message in memory. Before processing a subsequently detected message, the subsequent message is compared with the stored message. It they do not match, the subsequently detected message is subjected to further processing including voting, matching, validity, checking, etc. However, if they match, the subsequent message is ignored as a redundant message and a power savings mode is entered to conserve battery power. |
