The use of tactical callsigns helps clarify the function of individual stations. These tactical callsigns should be used in lieu of Amateur callsigns for all initial calls and for subsequent exchanges of traffic.  However, the station operator must still follow all FCC rules when operating the station.   Your Amateur callsign should be used at the end of an exchange or every ten minutes to satisfy FCC regulation 97.119. This is easily satisfied by terminating an exchange with your tactical callsign plus your FCC-assigned Amateur callsign.

If at all possible, tactical callsigns should be defined in advance of an event and distributed to participating stations for reference. Otherwise, Net Control should announce the tactical callsign assignments as a station assumes a particular function.   Using tacticals allows for smoother net operations as stations assigned to a specific station come and go there is no reason to know who is at the location, only what the tactical for that station is.

Weather Nets will have predeterminded tacticals as watch point locations already have designators. OMMRS hospitals also have pre-assigned designators.   Other nets may or may not be preassigned.  It is important that the operators use their callsign in accordance with FCC rules and regulatoins
