[aprssig] What is wrong here?

[John]

Hi,

I recently setup a digi in the garage and checking it on APRS.fi I get this:
2016-04-15 15:39:52 EDT: *K4AG-2 
<http://aprs.fi/?c=raw&limit=&call=K4AG-2>*>APN383,K4AG-6 
<http://aprs.fi/?c=raw&limit=&call=K4AG-6>,WF2C-1 
<http://aprs.fi/?c=raw&limit=&call=WF2C-1>,WIDE2*,qAR,KK4ZMG-5 
<http://aprs.fi/?c=raw&limit=&call=KK4ZMG-5>:!2539.11NS08021.53W 
*[Unsupported packet format]
*My other digi K4AG-6 is OK*
*What am I doing wrong?
Thanks,
John
