[aprssig] Tactical call signs

How can someone authenticate identity of a stations packets unless the callsign is in the packet?  What is the issuse about the callsign being in the header of the message?

If the retransmission of a message occurs without proper id of the station of origin isn't that a violation?

Do you want the hassle of having to prove who sent the message that your digi repeats?  How will you do that if the packets don't have the station of origin's callsign somewhere?

I shortened the part you quoted.  I'm assuming that is the particular
piece you are referring to.

Saying that the station needs to be authenticated by the first
forwarding station doesn't mean that the callsign needs to appear in
the header.  This section doesn't specify that an amateur callsign
must appear in the "from" area of the AX.25 header.  Under this
section, I (as a digi operator) can digipeat tactical callsigns so
long as I know that they are originated by an amateur.  It doesn't say
that I can't digipeat tactical calls, only that I need to authenticate
them or take responsibility for their content.
