No problem. The test was done using a script that I usually use for generating
APRS objects on a Linux box (actually running an IRLP node) and just needed
a bit of modification to send the objects and position reports with the lower
case nsew in the lat / long. It's really a plagiarized and modified copy of the
IRLP APRS script that I was using for the test. It makes it easy to test something
like this, other than a bit of trial and error and a peek at the APRS spec to get
the syntax correct.

If anyone wants to run a test but can't generate an object or position report
using lower case n & w (in this hemisphere) just let me know and I could
send one from here. You would have to either use a filter to get it from the
APRS-IS or arrange to gate it to RF so you could see it to see how your
client handled it. Note... it was UI-View32 2.03 that I was viewing the object
and position report in. I don't have any older versions or the 16 bit version
