<p dir="ltr">I can't tell you off hand what aprx does, but if you were to ask me, I'd say I'd want it to use the outgoing TX callsign, since I made the argument in my thesis that the last traced callsign may be used as part 97 identification. If I ever notice it doing something else, I would put it on my list to fix it in aprx. </p>

<div><div dir="ltr">I was just looking at the digipeat tracing code in my APRS program (YAAC), and started wondering which callsign should be used for tracing when doing a cross-band digipeat. For example, if the frame was received on the port with callsign AP0RT-1 and digipeated out both TNC's AP0RT-1 and AP0RT-2, which callsign should be used for the trace on the transmission out AP0RT-2? The receiving port (AP0RT-1)? The transmitting port (AP0RT-2)? Or both in receive-transmit order?<br>Just curious what the behavior should be for this.<br><br>Andrew, KA2DDO<br>author of YAAC<br> </div></div>
