Look at packets sent by some digi with UIDIGI ROM. One of them is WB9WOZ-15.
Checking http://www.findu.com/cgi-bin/find.cgi?call=WB9WOZ-15 there is no
any status. Because station does not send any packet with > as is stated in
APRSspec chapter 5, page 17: "every APRS packet contains an APRS Data Type
Identifier" and in the table below identifier for status is >
Checking packets of all kinds from WB9WOZ-15
http://www.findu.com/cgi-bin/raw.cgi?call=WB9WOZ-15&start=3&length=3&time=1
we see packets with position:
!4153.00NS08738.00W#PHG7560/NIAN.APRS.NET
The identifier is ! i.e. position without timestamp, no messaging. And in
addition we packets as:
UIDIGI 1.9 BETA 1
So, first character is U not > In such case APRS client can not read this
packet as station status. In the identifiers table U is marked as [do not
use]. According to APRSspec should be:
>UIDIGI 1.9 BETA 1

73!
