Abstract
A method for determining when a radio leaves a radio talk group includes the step of notifying a radio(s), such as the initiator of the call (step 308), that one or more members of the talk group left the talk group. This information allows for the initiator of the call or another radio to re-transmit the call at a later date, or to attempt to get the missing radios back into the talk group prior to transmitting another call.
