3. Signs Use of regular radio Call Signs is mandatory at the beginning and end of a radio conversation With the clear voice quality typical of radio systems today intermediate transmissions need not have the Call Signs used as this simply adds unnecessary radio traffic to the system 16 For ease of communication in emergency situations tactical call signs may be assigned on multi agency radio networks The tactical call signs will describe the radio operator s location or function Example The Incident Commander at a Dartmouth General Hospital incident might use the call sign Dartmouth General Incident Commander Calling Before transmitting the operator of every station shall listen for a period long enough to ensure that there will be no harmful interference to transmissions already in progress If such interference seems likely one must wait for the first break in transmission where he may intercede A station having distress urgency or safety communication to transmit is entitled to interrupt at any time when a transmission of lower priority is in progress Station Call When a station wishes to establish communication with another station it must transmit the following items in order Name of the station being called The words THIS IS Name of Station calling Invitation to reply OVER Replying When a station is ready to receive the communication it should reply in the following form Name of calli
