You're trying to send xastir_udp_client only the APRS data, whereas you really
have to fake out the entire TNC2-style packet.

xastir_udp_client localhost 2023 KN4QD PASS "KN4QD>APX201::BLNC     :test test test test"

So you're missing the KN4QD> source address, the APX201 TOCALL (or whatever 
TOCALL you choose to use), and the double colon indicating the end of the
header *and* the "APRS Message" data type.

Sorry it took so long to respond.  It took me a little while to work out what
was expected as the "APRS packet goes here" argument for xastir_udp_client.
If you do the whole fake packet (including to and from addresses, and the 
extra colon), the bulletin/announcement *will* show up in Xastir.   Note that
Xastir will NOT adopt the message as if it were its own, and will not 
re-transmit it on the decaying interval that it would do for its own 
messages.
