Abstract
A method and apparatus for scanning amongst two-way radios is disclosed. The method includes applying a scan probability index (SPI) to each member of a scan list, the SPI indicating a likelihood of channel activity. The SPI is dynamically updated by a variety of processes. Members are loaded from the scan list, and the SPI of the loaded member is compared to a threshold. Members are skipped or checked for activity based on the SPI passing or failing the threshold. Members having a sufficient SPI will proceed to have detected channel activity decoded. The method and apparatus may utilize both normal scan members and vote scan member frequencies.
