Interoperability Communications Order Model Communications Order Model refers to the order of the radio identification or callsign of the sender and receiver is spoken. The prevailing model in the U.S. has a common order in how a message is initiated. Often, this model is referred to a “Hey you, It’s me.” The sender states the unit/person called, followed by the sender’s unit or name. Example: “Dispatch, this is Engine 21.” The response is the reverse: “Engine 21, this is Dispatch, go ahead.” Establishing this order model increases interoperability so that units are aware which identification/callsign comes first. This model is used by the amateur radio community, the Department of Defense, the US Coast Guard, the National Guard, many public safety agencies across the country, and is endorsed by APCO and SAFECOM. ==================== zerg90 says - might be nice to add this rule - whoever starts the conversation says "channel clear" at the end - or something like that -- You received this message because you are subscribed to the Google Groups "massfire" group.
