John is right on the money here. -----
Tactical Call Sign SOP: A tactical call sign is entered in the 4 digit comment field after a station's legal call sign: MY: NAØG /EOC Such tactical calls can be readily pre-programmed in the MYCALL memory of most radios. With this procedure, your tactical call sign will appear on the screen of anyone receiving, conveying the information in an efficient manner, while not interfering in the D-Star routing protocol. Stations using anything other than their legal call sign in the call sign field should be informed they are are using BAD PRACTICE. ----- Just my 2 cents. The comment field is really wide open for transmitting all kinds of stuff. I might have the APRS code for my home: NAØG//- Others have suggested ARRL numbered radiograms: NAØG/RL16 (Property damage very severe in this area). And so on. The point is that with D-Star this comment field goes out with each press of the button, so why not use is for something useful? 73 de NAØG Gene > Here is my thought on this. > > Radios should be identified by their official callsign (and optional > designator character), tactical / special event callsigns can be put > into the 4 char comment, on voice, or in the message field for SMS. > Certainly, the local repeater could be allowed to pass tactical radio > callsigns, but across the network you are just asking for routing > errors if more than one station decides their callsign of the day is > "TAC1" or "BASE" or "EOC" (mitigated by registration, but then only > one station in the entire network can be "TAC1", in a dynamic > addressed network it would be anarchy). > > I know you know it, but the callsign is the routing address in D-STAR. > > The filter would have to be pretty "loose" but keep it to looking > something like a callsign and definitely could filter certain profane > words. > > > John Hays > Amateur Radio: K7VE > j...@... > > > > [Non-text portions of this message have been removed] >
